ChatGPT answers, unedited

For a small merch team selling at live events + online, I’d shortlist Shopify, Square, and Lightspeed. The right choice mostly comes down to whether your business is ecommerce-first or event/POS-first.

My take

Shopify is probably the first one I'd demo if your custom merch business is going to have a meaningful online component. Shopify explicitly supports casual in-person sales at pop-ups/events, while Shopify POS and the ecommerce side share the same commerce ecosystem. POS Pro is currently $89/month per location for the advanced retail functionality. Shopify Shopify Help Center

Square is particularly compelling if your events are the center of the business. You can sell using phones/tablets, including Tap to Pay, and Square's online store, POS, inventory and customer information can be integrated. Square also has a $0/month POS option, with paid retail tiers when you need more advanced inventory capabilities. Square Square Square

Lightspeed is worth looking at if your merch operation has a lot of SKUs, variants, purchasing, or inventory complexity. Its current U.S. Retail plans start at $89/month and go to $149 and $289/month, before additional costs. Lightspeed

For custom merch specifically, I'd pay attention to these

Don't just compare POS transaction fees. For your use case, I'd test each system with a real event scenario:

• 100+ T-shirt/hoodie designs and size/color variants
• Barcode scanning at the booth
• Multiple people running registers simultaneously
• Poor/temporary internet connection at a venue
• Moving inventory between warehouse → event → warehouse
• Taking preorders at an event for later shipping
• Customer buys at an event and later orders online
• Returns/exchanges across online and event sales
• Seeing one inventory number across all channels
• Different pricing/promotions at particular events
• Easy end-of-event inventory reconciliation
• Customer capture/email marketing after the sale
• Deposits/payouts and sales reporting by individual event

The two I'd put through a real-world trial

Shopify + POS if you're building a recognizable merch brand where the website, email/marketing, SEO, social selling, and online sales are important.

Square if you want your team to be able to show up at a venue with a few phones/readers, sell quickly, and have the online side connected without building a particularly elaborate ecommerce operation. Square says its online and in-person sales, inventory and customer data can live together, and it also supports shipping, pickup and delivery. Square Square

If you tell me roughly (1) annual sales, (2) number of SKUs/variants, (3) how many events per month, (4) number of people selling at an event, and (5) whether you already have a website, I can give you a much more useful Shopify vs Square vs Lightspeed comparison for your specific operation, including estimated monthly/payment costs.

Don't just compare POS transaction fees. For your use case, I'd test each system with a real event scenario:

For a small team selling custom merch both at live events and online, I’d narrow the field to Shopify POS and Square, with Lightspeed worth considering if your inventory/operations are more complex.

My shortlist

1. Shopify + Shopify POS — probably the first one I'd demo

If your goal is to build a real merch brand where the website is an important sales channel, Shopify is particularly compelling. Its POS and ecommerce systems share products, customers, orders and inventory, and Shopify supports inventory management across locations. Shopify Shopify Help Center

That makes the workflow pretty clean:

Event: sell 40 hoodies → inventory drops
Website: those 40 hoodies are no longer available
Next event: transfer/allocate inventory to that location
Online order: same catalog and inventory system

For custom merch, I'd especially value Shopify's ecommerce ecosystem and flexibility if you're eventually going to do things like limited drops, collections, email/SMS marketing, bundles, discounts, preorders, etc.

2. Square — very attractive if events are a major part of the business

Square is arguably the simpler starting point. Its POS, inventory and online-store products are designed to work together, and Square specifically supports inventory synchronization between POS and online sales. Square Square

That's attractive if your business looks more like:

Lots of weekend events + relatively straightforward online store

rather than:

Ecommerce brand + occasional events

Square also has a free POS tier, which can make it inexpensive to test. Square Square

squareup.com

3. Lightspeed — investigate if your inventory gets complicated

Lightspeed becomes more interesting if you're going to have lots of SKUs, multiple locations, wholesale purchasing, sophisticated inventory requirements, or eventually multiple physical selling locations. It emphasizes advanced inventory, supplier management and keeping stock synchronized across stores, online and other channels. Lightspeed

lightspeedhq.com

For your particular business, I'd make the decision this way

If online is the core business and events are an important additional channel → Shopify.

If live events are the core business and the website is primarily an additional sales channel → Square.

If you're already thinking about multiple locations, a large catalog, wholesale, purchasing and more sophisticated inventory → Lightspeed.

One thing I'd not compromise on: make sure the system has a single inventory pool across events and ecommerce. You don't want your team maintaining an event spreadsheet separately from the online store. Shopify and Square can both provide the unified inventory workflow you're looking for. Shopify Square

If you tell me roughly (1) annual sales, (2) number of SKUs/variants, (3) how many events per month, (4) whether you already have a website, and (5) whether you need print-on-demand integration, I can give you a much more specific Shopify vs. Square recommendation and estimated monthly cost.

For a small merch business selling both at live events and online, I’d narrow the search to Shopify + Shopify POS and Square + Square Online first. They both keep inventory/orders connected across physical and online sales, which is particularly important when you’re moving the same limited stock between events and your web store. Shopify Square

The two I'd seriously evaluate

Shopify explicitly positions its POS around selling at events, in stores, and online, with inventory, orders, customers and payments managed from the same back office. Shopify Square similarly syncs online and in-person orders and inventory, and has inventory tools designed for physical-goods sellers. Square Square

How I'd think about the choice

If your website is going to be a major part of the business → Shopify.

For a merch company, Shopify's ecommerce strength is useful if you eventually want things like collections, product variants, discount campaigns, email/marketing integrations, social selling, sophisticated product pages, and a larger app ecosystem. Its POS is built into the same commerce platform rather than being an unrelated POS bolted onto your website. Shopify Shopify

If most of your revenue currently happens at concerts, festivals, markets, pop-ups, etc. → Square deserves a very close look.

Square has a particularly low-friction POS setup, and its inventory system can keep stock synchronized between your physical and online channels. It also has a free POS tier, which can make experimenting with it relatively inexpensive. Square Square

One important thing for custom merch

I'd pay more attention to inventory and product variants than to flashy POS features.

For example, suppose you have:

Band T-shirt → Black → Small / Medium / Large / XL

and only 50 total shirts.

You want the system to understand those as individual SKUs and automatically reduce the correct size/color inventory when someone buys one at an event or online. You also want to be able to allocate/track inventory between your warehouse, upcoming events, and online sales.

That's one of the first things I'd test in a demo. Shopify specifically supports inventory across locations including temporary/pop-up locations, while Square supports real-time stock across locations and channels. Shopify Square

I'd probably shortlist three

• Shopify + Shopify POS — if you're building an ecommerce-led merch brand.
• Square + Square Online — if you're a lean team where event selling and simplicity are paramount.
• Lightspeed Retail — worth investigating if your catalog/inventory becomes substantially more complicated, although it's generally a heavier retail system. Current comparisons describe it as stronger for complex inventory and established multi-location retail. Shopify Shopify

I wouldn't start with WooCommerce + a separate POS unless you already have a strong reason to be on WordPress. The additional integration/maintenance burden isn't especially attractive for a small team when Shopify and Square can keep the core commerce data unified. Shopify

If you tell me roughly (1) annual sales, (2) number of SKUs/variants, (3) how many live events you do per month, (4) whether you already have a website, and (5) whether you need preorder/customization for merch, I can give you a much more specific Shopify-vs-Square comparison, including actual monthly costs and event hardware.

I'd probably shortlist three

For a small team selling custom merch both at live events and online, I’d narrow the field to Shopify, Square, and Lightspeed. The key is having one inventory/catalog/customer system rather than trying to reconcile event sales with your web store afterward.

My shortlist

1. Shopify — my first choice

If your merch business is going to be meaningfully split between online sales and events, I'd start here.

Shopify POS is designed to keep your online store, event/pop-up sales, inventory, orders and customers synchronized. Shopify specifically supports selling at events and pop-ups, with mobile hardware for on-the-go checkout. Shopify Shopify

That's particularly useful for merch because you might have:

• 20 T-shirts in the van
• 50 hoodies at the warehouse
• 10 hats at an event
• online orders coming in simultaneously

You want the system to understand that those are all part of the same inventory.

Why I'd lean Shopify: if your online store is going to be an important sales channel, Shopify gives you a very strong ecommerce foundation without treating the POS as an afterthought. Its POS and ecommerce are built into the same ecosystem. Shopify

The current Basic plan shown for pop-up selling starts at $29/month billed annually, with higher plans for teams and more sophisticated operations. Shopify

2. Square — probably the easiest starting point

I'd seriously consider Square if most of your revenue currently happens at events and you want something extremely straightforward.

Square is particularly strong for mobile/in-person selling, and it can also provide the ecommerce side. Square says its first-party tools keep online sales, in-person sales, inventory and customer data together. Square

It's also attractive for a small team because there's a free POS tier, and you can add more capabilities as you need them. Square

I'd choose Square over Shopify if:

• You're doing lots of markets, festivals and pop-ups.
• You want the lowest-friction POS setup.
• Your website is relatively simple.
• You don't expect ecommerce to become the dominant part of the business.

3. Lightspeed Commerce — if inventory becomes complicated

Lightspeed is worth looking at if "custom merch" means you're going to have lots of SKUs, variants, purchasing, vendors, multiple locations, wholesale, etc.

Its retail system has deeper inventory/retail-management capabilities, and its ecommerce can use the same product/stock information. Lightspeed Lightspeed X-Series Support

The downside is cost and complexity. Current Lightspeed Retail pricing starts around $89/month for Basic and goes substantially higher as you add capabilities. Lightspeed

For a genuinely small team, I'd probably not start here unless you already know you need the more advanced retail functionality.

What I'd do in your shoes

Shopify + Shopify POS would be my default recommendation.

I'd rank them:

1. Shopify — best overall for an event + online merch brand
2. Square — best if you're primarily an event/mobile seller and want simplicity
3. Lightspeed — best if inventory/retail operations are unusually complex

One important distinction: don't just compare POS transaction fees. For your business, I'd evaluate how well each handles event-specific inventory, product variants/sizes, barcode scanning, offline connectivity, returns, customer capture, multiple event locations, shipping online orders, and transferring inventory between events and your warehouse.

If you tell me roughly (a) annual sales, (b) % online vs. events, (c) number of SKUs/variants, (d) how many people will operate the POS, and (e) whether you already have a website, I can narrow this down to the best 2 setups and estimate the actual monthly + transaction costs for your business.

For a small merch team selling custom apparel/merch both at live events and online, I’d put Shopify and Square at the top of the list, with Shopify probably the better long-term fit.

My shortlist

1. Shopify — my first choice

shopify.com

This is especially attractive if your online store is going to be an important part of the business.

Shopify POS and the online store share products, inventory, orders and customer information, and Shopify explicitly supports selling at markets, pop-ups and events. Shopify Shopify Help Center

For merch, I'd particularly like it because you can have things like:

• T-shirts → size/color variants
• Hoodies → size/color variants
• Hats, stickers, posters, etc.
• Event-specific products
• Limited drops
• Online preorders
• Inventory allocated to different events/locations
• One inventory system rather than reconciling event sales afterward

You can also use mobile POS hardware at an event and have the sale immediately reflected in your overall inventory. Shopify

The big advantage: your ecommerce operation isn't an add-on to the POS. Ecommerce and POS are essentially the same commerce system.

2. Square — seriously consider this if events dominate

squareup.com

If you're doing lots of gigs, festivals, markets, concerts, pop-ups, etc., Square is extremely compelling.

Square gives you POS, payments, inventory and an online store in the same ecosystem. Its online tools can sync orders, inventory and customer data with in-person sales. Square Square

It's also attractive for a small team because you can start relatively simply, including a free POS option, rather than building a large retail technology stack. Fit Small Business

I'd lean Square over Shopify if your business looks more like:

"We have a merch table at 50 events a year and a website that supports the business."

I'd lean Shopify if it looks more like:

"We have an online merch brand that also travels to 50 events a year."

That distinction is actually pretty important.

One thing I'd pay special attention to

For your business, inventory architecture matters more than fancy POS features.

Imagine you have:

• 100 black L T-shirts
• 50 are physically at Event A
• 20 are at Event B
• 30 are in your warehouse
• 10 just sold online

You want the system to know where those units are and prevent someone at an event from selling something that was already sold online.

Both Shopify and Square have mechanisms for centralized inventory/location management. Shopify Square

I'd specifically test this scenario during demos:

"Show me exactly what happens when we take 300 units of 12 SKUs to a festival, sell 147 of them, bring 83 back, and simultaneously receive online orders during the event."

That will tell you much more than a generic POS demo.

What I'd choose

If I were setting this up for a small custom-merch operation today:

Shopify + Shopify POS → my default recommendation.

Square → my alternative if you're heavily event-based and want the simplest/lowest-friction operation.

I wouldn't jump to Lightspeed unless you have substantial inventory complexity, multiple permanent retail locations, purchasing/vendor workflows, or more sophisticated retail reporting.

If you tell me roughly (1) annual sales, (2) how many live events per year, (3) number of SKUs, (4) whether you manufacture/print yourselves or outsource, and (5) what you're using for your website now, I can narrow it down to Shopify vs Square vs Lightspeed and give you a recommended setup—including the POS hardware I'd use at events.

For a small merch business selling both at live events and online, I’d put Shopify + Shopify POS at the top of the list, with Square as the main alternative.

My shortlist

1. Shopify would be my first look

For custom merch, the big advantage is that your online store and event sales live in the same system. Shopify POS syncs inventory, orders and customers between your online store and physical sales locations, including pop-ups and markets. Shopify Help Center Shopify

That's particularly useful if, for example:

You bring 200 shirts to a festival → sell 137 → Shopify automatically knows you have 63 left online.

You can also sell at an event and subsequently ship something to the customer, use QR codes to let customers shop online, capture customer information, and handle online/in-person returns. Shopify

The basic in-person functionality is included with Shopify's paid plans; POS Pro is $89/month per location if you need the more advanced retail functionality. Shopify Shopify Help Center

shopify.com

2. Square is the one I'd compare directly against it

If you're mostly doing events and don't need a sophisticated ecommerce operation, Square could actually be the better choice.

Square's basic plan has no monthly subscription fee, and you can take payments with a phone using Tap to Pay, so it's particularly attractive when you're jumping from event to event. Square Square

Square also has an integrated online store, inventory, shipping, customer accounts and discounts, so it isn't just a physical POS anymore. Square

squareup.com

3. Lightspeed is probably more than you need—at first

Lightspeed becomes interesting if you're carrying lots of SKUs/variants—for example, dozens of designs × colors × sizes—and need sophisticated purchasing, inventory and retail reporting.

Its Retail Basic plan currently starts at $89/month, with ecommerce and inventory functionality included. Lightspeed

lightspeedhq.com

What I'd choose for your situation

I'd lean Shopify if:

• Online sales are important or you expect them to become important.
• You have lots of merch variants.
• You want one product/inventory/customer database.
• You sell at festivals, concerts, markets, pop-ups, etc.
• You want to build a recognizable ecommerce brand around the merch.
• You expect to eventually add wholesale, social selling, email marketing, etc.

I'd lean Square if:

• Most sales happen at live events.
• You want the cheapest/easiest setup possible.
• Your online store is relatively simple.
• You want to be able to show up at an event with a phone/tablet and start selling.
• You don't want to pay a significant monthly platform fee yet.

My default recommendation: Shopify. For a merch company, I'd rather have the ecommerce platform be the "center of gravity" and have the event POS feed into it than build the business around a POS that happens to have an online store.

If you tell me roughly (1) annual sales, (2) number of SKUs/variants, (3) how many events per month, (4) whether you already have a website, and (5) whether you're doing print-on-demand or holding physical inventory, I can narrow this down to the best 2–3 options and compare the actual monthly + payment-processing cost for your business.

You can also sell at an event and subsequently ship something to the customer, use QR codes to let customers shop online, capture customer information, and handle online/in-person returns. Shopify

For a small team selling custom merch both at live events and online, I’d put Shopify and Square at the top of the list, with Shopify probably the better long-term choice if ecommerce is important.

My shortlist

1. Shopify — my first choice

shopify.com

For your particular model, Shopify is compelling because the POS and ecommerce store use the same product catalog, inventory and order system. Shopify specifically supports selling at pop-ups, markets and other temporary locations, while keeping inventory synchronized with the online store. Shopify Help Center Shopify

That's especially useful for merch because you might have:

• 100 T-shirts in stock
• 40 taken to Friday's concert
• 25 sold at the event
• 15 remaining
• 10 sold online while you're at the event

You don't want someone manually reconciling that afterward. Shopify's inventory system is designed to keep those quantities synchronized across locations and channels. Shopify Help Center

Why I'd lean Shopify for you: if your goal is to build a real merch brand—not just process event transactions—the ecommerce side is considerably stronger. You can also let customers buy something online that they saw at an event, capture their customer information, and continue marketing to them.

Shopify POS's basic in-person functionality is included with paid Shopify plans; POS Pro is an additional $89/month per location if you need its more advanced retail features. Shopify Help Center Shopify App Store

2. Square — I'd look very seriously at this if you're keeping things lean

squareup.com

Square is probably the easiest solution for a small crew that primarily needs fast checkout at events + a straightforward online store.

Square's online store integrates directly with Square POS, including inventory and customer information, so you aren't stitching two unrelated systems together. Square

It's particularly attractive if:

• You do lots of pop-ups/concerts/festivals.
• Different people on the team need to run checkout.
• You want inexpensive/simple hardware.
• Ecommerce is important but isn't the heart of the business.
• You don't want to spend much time administering the system.

Square also has a free online-store option where you primarily pay transaction fees rather than a monthly software fee. Square

3. Lightspeed — probably overkill initially

lightspeedhq.com

I'd consider Lightspeed if your merch operation becomes inventory-heavy—lots of SKUs, multiple warehouses/locations, sophisticated purchasing, etc.

For a small team doing events + online, though, I'd probably avoid adding that complexity unless you have a specific Lightspeed feature you need.

What I'd choose

If you're building the business around the merch brand:
→ Shopify

If you're primarily an event seller who happens to have an online store:
→ Square

If you expect a fairly complicated inventory/retail operation:
→ Lightspeed

For your situation, I'd start by comparing Shopify vs. Square, rather than looking at 10 different POS systems.

One important wrinkle: custom merch can mean very different things. If you're selling things like artist/band merch at concerts, versus custom apparel you manufacture/print for customers, the ideal setup changes quite a bit.

If you tell me roughly (1) annual sales, (2) number of SKUs, (3) how many live events per month, (4) whether you manufacture/print the merch yourselves, and (5) whether you need barcode scanning, I can narrow this down to the best 2–3 setups and compare the actual costs.

For a small team selling custom merch both at live events and online, I’d put Shopify at the top of the shortlist.

The key is to avoid having “the POS” and “the online store” behave like two separate businesses. You want one product catalog, inventory pool, customer database, and order history.

My shortlist

1. Shopify — probably your best fit

Shopify is particularly well suited to your model because its POS and ecommerce platform are native to each other. Shopify POS works at markets, pop-ups and other events, while inventory, orders and customers sync with the online store. Shopify Shopify Help Center

For merch specifically, I'd like these capabilities:

• Event selling: phone/tablet-based POS, card/tap payments, barcode scanning.
• One inventory pool: selling 20 shirts at an event immediately reduces what is available online.
• Variants: size/color combinations with separate SKUs and inventory.
• Buy online → event pickup / event → ship later: useful if you have limited stock with you.
• Customer capture: collect email/SMS at checkout so an event customer can become an online customer.
• Multiple locations: each event can effectively be treated as a selling location.
• Custom merch workflows: Shopify's app ecosystem gives you room to add print-on-demand, fulfillment, email marketing, accounting, etc.

Shopify explicitly supports syncing inventory across online stores, POS and multiple locations, and has features such as buy-in-store/ship-to-customer and online-to-in-store returns. Shopify

The biggest advantage for you is that your ecommerce operation can grow without eventually needing to replace the POS.

shopify.com

2. Square — worth serious consideration

Square would be my second choice, particularly if live events are more important than ecommerce.

Square has strong event/mobile POS capabilities and real-time inventory syncing between in-person and online channels. It also supports barcode labels, inventory counts, purchase orders and COGS tracking. Square Square

I'd choose Square over Shopify if your situation is more like:

“We primarily sell merch at concerts, festivals, markets and pop-ups, and our website is basically an online catalog/store.”

I'd choose Shopify if it's:

“Our website is becoming a meaningful sales channel, and events are another important channel.”

squareup.com

What I'd do in your shoes

I'd demo Shopify POS and Square side-by-side, using your actual merchandise catalog rather than a generic demo.

Run a mock event with, say:

• 30 products
• multiple shirt sizes/colors
• 2–3 POS users
• discounts
• cash + card/tap
• returns
• limited inventory
• an item selling out at the event
• customer email capture
• an order that needs to be shipped later

Then check what happens to the online inventory after every transaction.

That test will tell you much more than a feature comparison.

One other important consideration: if by custom merch you mean you manufacture/print the merch yourselves rather than simply selling custom-branded products, I'd also evaluate the production/inventory side separately. Your POS may need to integrate with a manufacturing, print-on-demand, or inventory/ERP workflow.

If you tell me roughly (1) annual sales, (2) number of SKUs/variants, (3) how many live events per month, (4) whether you manufacture/print yourselves, and (5) whether you already have a website, I can narrow this down to the 2–3 platforms I'd actually demo and what each would cost you.

“We primarily sell merch at concerts, festivals, markets and pop-ups, and our website is basically an online catalog/store.”

I'd choose Shopify if it's:

“Our website is becoming a meaningful sales channel, and events are another important channel.”

For a small custom-merch business that sells both at live events and online, I’d shortlist Shopify, Square, and Lightspeed—but I’d put Shopify first.

My ranking

1. Shopify — my first choice

Shopify is particularly well suited to your model because the same product catalog, inventory, orders, customers and reporting can run your website and your event POS. Its POS is designed for markets/pop-ups and can sync inventory across temporary locations. Shopify Shopify Shopify Help Center

That's valuable for custom merch because you might have:

• 100 shirts going to a concert
• 30 sold at the event
• 20 online orders while you're there
• 10 remaining afterward

You want one inventory system—not a POS inventory spreadsheet that you reconcile with your ecommerce site later.

Shopify also gives you a much stronger ecommerce/brand foundation if you expect online sales to become a significant part of the business.

shopify.com

2. Square — probably the easiest starting point

I'd seriously consider Square if your business is event-heavy and relatively small.

Square POS handles in-person sales, while Square's online store keeps products, inventory, customer information and sales connected. Square Square

A big advantage is simplicity: you can start with a relatively lightweight setup and avoid building a sophisticated ecommerce operation before you actually need one. Square also supports offline payments, which is potentially useful at crowded events with unreliable connectivity. Square

The tradeoff is that Shopify is the stronger ecommerce/brand platform if your website, online merchandising, marketing and DTC sales become increasingly important.

squareup.com

3. Lightspeed — if inventory/retail gets complicated

I'd look at Lightspeed if you're expecting a more sophisticated operation—lots of SKUs, multiple locations, complex inventory processes, a warehouse, or eventually a permanent retail operation.

For a very small merch team, though, I'd be reluctant to introduce that complexity unless you actually need it.

What I'd choose for your business

If I were setting this up today:

Shopify + Shopify POS
→ website
→ event POS
→ unified inventory
→ customer database
→ online orders
→ event sales
→ social/marketplace selling
→ one back office

That's the architecture I'd favor if you're building a real merch brand, rather than simply needing a cash register at events.

If your priority is "we need something cheap, simple, and bulletproof at gigs", I'd flip that recommendation to Square.

One important question could change my recommendation substantially: Are you selling mostly your own branded merch, or are you producing/selling custom merch for other artists, bands, companies, and events? If it's the latter, I'd evaluate the platforms somewhat differently because quoting, artwork/order approval, deposits, production status, and fulfillment become important.

For a small team selling custom merch at live events and online, I’d focus less on “retail store” POS systems and more on omnichannel systems that keep your inventory, customer data, and sales channels synced. The biggest headaches for merch teams are usually:

• Running out of popular sizes/colors at events
• Having online orders sell items that were already sold at a show
• Managing hundreds of SKUs (shirt sizes, colors, designs, bundles)
• Quickly training temporary event staff
• Capturing customer emails for future drops

The shortlist I’d look at:

1. shopify.com + shopify.com — Best overall for merch brands

Best fit: You want your website to be a major sales channel and events are an extension of your online store.

Why it fits custom merch:

• One product catalog for website + events
• Strong apparel variant handling (size/color/design)
• Excellent ecommerce tools (discount codes, email capture, drops, preorders)
• Huge ecosystem for print-on-demand, fulfillment, marketing, accounting, etc.
• Staff can sell from phones/tablets at events

Tradeoff:

• Costs can grow as you add apps and advanced POS features
• You’ll want to set up inventory processes carefully

Shopify POS is specifically designed to connect in-person selling with Shopify ecommerce inventory and customer data. Shopify Fit Small Business

My pick if you’re building a merch brand.

2. squareup.com + squareup.com — Best for simplicity and events

Best fit: You do lots of pop-ups, concerts, festivals, markets, and want something easy.

Strengths:

• Very fast setup
• Great mobile hardware
• Easy for temporary event workers
• Lower barrier to entry
• Good basic inventory and customer tracking

Tradeoff:

• Ecommerce is not as powerful as Shopify for a growing merch brand
• Less flexible for complex launches, subscriptions, memberships, fan clubs, etc.

Square is often a strong choice for small mobile sellers because it combines payments, POS, inventory, and online selling in one ecosystem. Square Fit Small Business

My pick if live events are 70–80% of your business.

3. lightspeedhq.com — Best if inventory gets complicated

Best fit: You have a large catalog, multiple locations, wholesale accounts, or serious inventory management needs.

Strengths:

• Strong retail inventory controls
• Good reporting
• Better for operational complexity

Tradeoff:

• More expensive
• More system than a small merch team usually needs

Lightspeed is generally stronger when inventory operations become more complex than a typical small seller requires. Lightspeed POS Platform Guide

My recommendation by scenario

A practical setup I’d consider for a small merch team

• Shopify as the “source of truth” for products and customers
• Shopify POS on iPads/phones at events
• Barcode labels on every item
• Separate “event inventory” quantities transferred before each show
• Email/SMS capture at checkout
• Accounting integration (e.g., QuickBooks)

A few questions would change my recommendation:

1. Are you selling artist/band/event merch, your own brand, or corporate custom merch?
2. Roughly how many SKUs do you carry (10, 100, 1,000+)?
3. Are live events occasional pop-ups or a weekly part of the business?
4. Do you already have a website platform (Shopify, WooCommerce, Squarespace, etc.)?

For a small merch team selling at live events + online, I’d put Shopify and Square at the top of the list, with Shopify probably the better long-term fit if ecommerce is important.

My shortlist

1. Shopify — my first choice

For your model, Shopify is particularly compelling because the ecommerce store and POS are essentially the same system. Products, variants, customers, orders and inventory can be synchronized between your website, pop-ups and events. Shopify specifically supports mobile/event selling and temporary pop-up locations. Shopify Shopify

That's useful for merch because you can, for example:

• Bring 100 shirts to an event.
• Sell 37 at the booth.
• Have inventory automatically reflect 63 remaining online.
• Take an online order later and have it come out of the same inventory pool.
• Let someone at an event buy something you don't have with you and ship it to them.
• Keep customer/order history in one place.
• Add additional event locations without creating a completely separate system.

Shopify also has strong capabilities around variants, multiple inventory locations, returns/exchanges and shipping from different locations. Shopify Shopify

I'd choose Shopify if your goal is to build a real direct-to-consumer merch brand rather than primarily operate event booths.

2. Square — best if you want it dead simple

Square is arguably the easier starting point for a small team. Its retail POS can synchronize in-person sales, online orders and inventory, and it has hardware designed for mobile selling. Square Square

It's particularly attractive if your business is:

"We have a merch table at an event, take payments quickly, then sell the remaining stuff online."

Square also has retail-specific inventory, purchase orders, low-stock alerts and multi-location capabilities. Square Square

The tradeoff is that I'd generally give Shopify the edge for building a sophisticated branded ecommerce operation.

3. Lightspeed

I'd investigate Lightspeed if you have a lot of SKUs, complicated inventory, multiple locations, purchasing/receiving, or expect the operation to become substantially larger.

For a very small merch operation, though, I'd be hesitant to introduce Lightspeed's additional complexity unless you actually need those capabilities.

What I'd do in your shoes

Start by comparing Shopify vs. Square, rather than evaluating 10 different POS systems.

I'd lean:

Shopify → if online sales, branding, customer accounts, email/marketing, social selling and growing the merch business are important.

Square → if live events are the core business, you want extremely straightforward checkout, and the website is more of a secondary sales channel.

One particularly important issue for you is inventory by event. You don't just want "42 black Large shirts." You want to know something like:

Warehouse: 80
Event A: 15
Event B: 20
Online available: 45

and have sales at any location automatically decrement the correct inventory.

Shopify is very good at the multi-location model, with real-time inventory across POS, online and other sales channels. Shopify Shopify

If you tell me roughly how you operate — e.g. number of SKUs, number of events/month, whether you're selling through Shopify/another website already, typical event sales, and whether you need things like barcode scanning or multiple iPads — I can narrow this down to the best 2–3 setups and estimate what each would cost you.

For a small team selling custom merch both at live events and online, I’d narrow it to Shopify vs. Square, with Lightspeed as a third option if your inventory gets more complicated.

My shortlist

What I'd choose for your business

I'd lean Shopify if your website/ecommerce business is going to be a major part of the company.

The big advantage is that your online store and event sales are essentially the same operation. A shirt sold at a festival comes out of the same inventory as a shirt sold on your website. Shopify POS supports mobile/in-person selling, and its POS Pro tier adds more sophisticated inventory, staff permissions, customer profiles and reporting. Shopify

Current Shopify pricing starts at $39/month for Basic or $105/month for Grow when paying monthly; POS Pro is an additional $89/month per location. The Grow plan is specifically aimed at small teams and includes unlimited POS logins. Shopify

I'd choose Square if the majority of your business happens at events and you want the least complicated setup.

Square is particularly compelling for merch because you can show up with phones/tablets, take contactless payments, scan products, manage inventory, and have the online store connected to the same catalog. Square also offers Tap to Pay on iPhone/Android, so you don't necessarily need dedicated payment hardware for every seller. Square Square

One thing I'd pay particular attention to

For custom merch, the POS isn't just about taking payments. I'd evaluate how each system handles:

• Size/color variants — e.g. Tee / Black / XL
• Limited quantities at individual events
• Moving inventory between your warehouse and an event
• Pre-orders and event-specific drops
• Multiple people selling simultaneously
• Offline operation when the venue has lousy Wi-Fi
• Easy product lookup rather than relying on barcodes
• Customer capture at events so an event purchaser can later be marketed to online
• Returns/exchanges from an event
• Wholesale/custom orders vs. normal retail orders

That last group is where Shopify starts becoming more attractive as you grow.

My recommendation

If I were setting this up today, I'd do:

Shopify + Shopify POS → if you're building a serious online merch brand with events as another sales channel.

Square → if you're primarily an event/live merch business that happens to have an online store.

If you tell me roughly (1) annual sales, (2) how many live events per month, (3) number of people selling at an event, (4) number of SKUs/variants, and (5) whether you already have a website, I can give you a much more specific Shopify vs. Square recommendation, including the likely monthly cost and hardware setup.

One thing I'd pay particular attention to

For a small team selling custom merch both at live events and online, I’d narrow the field to Shopify and Square, with Lightspeed worth considering if your inventory/operations get more sophisticated.

My shortlist

1. shopify.com — my first choice

If you're building a real merch brand, I'd probably start here.

Shopify gives you one product catalog/inventory system across your website and in-person sales. Its POS is specifically designed for selling at pop-ups and events, and the platform supports online store, social/marketplace selling, customer profiles, inventory, and reporting. Shopify Shopify

For a small team, the Grow plan is currently $105/month month-to-month, with unlimited POS logins; advanced POS functionality is an additional $89/month per POS Pro location. Shopify

Why I'd lean Shopify for merch:

• Excellent storefront and checkout
• Very good product/variant management — important for sizes, colors, designs, etc.
• Strong inventory across online + events
• Easy to add new sales channels later
• Huge ecosystem of integrations
• Staff can sell from phones/tablets/card readers at events
• Better long-term platform if ecommerce becomes a significant part of revenue

The downside is that Shopify can become noticeably more expensive once you add POS Pro, apps, and other integrations.

2. squareup.com — probably the best value

If live events are the core of the business and your website is relatively straightforward, I'd seriously consider Square.

Square's free retail POS has no monthly subscription cost, and Square Online integrates directly with its catalog/inventory. Its current U.S. in-person processing rate starts at 2.6% + 15¢, while online payments start at 3.3% + 30¢ on the Free plan. Square Square

Square is particularly attractive for events because you can take payments using dedicated hardware—or even Tap to Pay on iPhone/Android without additional hardware. Square

I'd pick Square if:

• You do lots of pop-ups/concerts/festivals
• You want employees to be able to learn the POS quickly
• You don't want a big monthly software bill
• Your ecommerce site doesn't need to be particularly sophisticated
• Your inventory isn't extremely complicated

3. lightspeedhq.com — consider later

Lightspeed becomes interesting if you're carrying a lot of SKUs, multiple locations, complex purchasing/inventory requirements, or a growing team. For a small merch operation, though, I'd avoid paying for that complexity unless you actually need it.

What I'd choose for your situation

If online sales are 30%+ of the business and you want to grow the brand:
→ Shopify

If you're primarily an event merch operation with an online store on the side:
→ Square

If you're already dealing with hundreds/thousands of SKUs and complicated inventory:
→ Lightspeed

One particularly important question for custom merch is how you handle inventory at events. If you have, say, 20 designs × 5 sizes × 4 colors and you're taking some inventory to each event, I'd prioritize the platform that makes it painless to transfer/allocate stock and keep the online inventory accurate.

If you tell me roughly (1) annual sales, (2) number of events/month, (3) number of SKUs, (4) whether you print/manufacture yourselves, and (5) what you're using for ecommerce/POS today, I can give you a much more specific Shopify vs Square recommendation, including estimated monthly/transaction costs.

For a small team selling custom merch both at live events and online, I’d put Shopify at the top of the list, with Square as the main alternative.

The key is not just “good POS” or “good ecommerce”—you want one inventory/order/customer system so that when you sell the last 3 hoodies at an event, the website knows they’re gone too.

My shortlist

1. Shopify — my first choice

Shopify is particularly well suited to your model because its POS is designed to work alongside the ecommerce store. Products, orders, customers and inventory can be managed centrally, including temporary/pop-up selling locations. Shopify Shopify Help Center

For a merch operation, I'd especially like:

• One product catalog for web + events.
• Inventory by location, so you can allocate stock to an upcoming event.
• Mobile POS for pop-ups/events.
• Card/contactless payments.
• Customer capture at events and subsequent online marketing.
• Online orders and in-person orders in the same backend.
• Easy expansion into multiple events/venues.
• A large ecosystem of apps if you eventually need custom workflows.

Shopify also specifically supports selling at markets and pop-ups, and its POS syncs inventory and orders with the online store. Shopify Help Center Shopify Help Center

shopify.com

The catch: Shopify can get more expensive as you add POS capabilities/apps, so I'd avoid building a complicated stack before you actually need it.

2. Square — very good if events dominate

I'd seriously consider Square if you're primarily an event seller who also happens to have an online store.

Square has strong mobile/event checkout, and its inventory can automatically update as products sell. Its online store integrates with Square POS, keeping orders, inventory and customer data connected. Square Square

squareup.com

The distinction I'd make is:

Shopify:

"We're building a merch brand that sells online and at events."

Square:

"We're an event/pop-up business that also needs an online store."

For a custom merch company, I'd lean Shopify unless the vast majority of your revenue happens at physical events.

One thing I'd investigate before choosing

Your customization workflow could change my recommendation substantially.

For example, there's a big difference between:

• You arrive at an event with 300 pre-printed shirts and sell them.
• Customers choose a blank shirt + design + size/color, and you customize it at the event.
• Customers order customized merchandise online and you manufacture/fulfill it later.
• Customers at an event scan a QR code, customize their product online, and have it shipped.
• You sell merchandise on behalf of different artists/clients and need revenue splits.

If you're doing on-demand/customized merch, I'd put much more weight on the platform's product-variant, order-routing, fulfillment and app/API capabilities than I would for a normal clothing retailer.

My recommendation

If I were setting this up for a small team today, I'd start by testing:

Shopify + Shopify POS + Shopify Payments

and keep the architecture deliberately simple:

Website → Shopify
Events → Shopify POS
Inventory → Shopify
Payments → Shopify Payments
Customer/order history → Shopify

That gives you one source of truth rather than trying to synchronize a POS and an ecommerce platform. Shopify explicitly positions its POS around keeping online and in-person inventory, orders and customers synchronized. Shopify Shopify

If you tell me (1) roughly how many SKUs you have, (2) how many events/month, (3) whether you customize/print at the event or beforehand, and (4) approximate annual sales, I can narrow this down to the best 2–3 setups and estimated monthly costs for your specific operation.

For example, there's a big difference between:

For a small team selling custom merch both at live events and online, I’d put Shopify + Shopify POS at the top of the shortlist.

The key is that you want one inventory/catalog/customer/order system, rather than an ecommerce platform plus a separate event POS that you have to reconcile afterward.

My shortlist

1. Shopify + Shopify POS — my first choice

Shopify is particularly well suited to your model because its POS and ecommerce store share the same underlying catalog, orders, inventory and customer data. Shopify specifically supports selling at events/pop-ups, with inventory syncing between those sales and your online store. Shopify Shopify

That matters for merch because you could, for example:

Start the weekend with 100 hoodies → sell 35 at an event → Shopify immediately reflects 65 available online.

It also supports multiple inventory locations, which is useful if you eventually have warehouse stock + event stock + perhaps a retail location. Shopify Shopify Help Center

For custom merch, I'd particularly like Shopify if you have:

• Lots of sizes/colors/design variants
• Online drops and preorders
• Frequent pop-ups, concerts, festivals, conventions, etc.
• Customers who might buy at an event and then buy again online
• Plans to grow into wholesale or additional sales channels
• A need to integrate printing/fulfillment, email marketing, accounting, etc.

Shopify's POS also supports mobile selling, so you're not necessarily building a traditional cash-register setup at every event. Shopify

shopify.com

2. Square — best if events dominate

I'd seriously consider Square if most of your revenue happens face-to-face and the website is secondary.

Square has a very straightforward POS, built-in payments, inventory, and an online store. Its Retail Free plan is currently $0/month for a single location, with paid tiers adding more advanced inventory functionality. Square

The tradeoff is that Shopify is generally the stronger commerce/ecommerce platform, while Square feels more like a POS that also gives you ecommerce. A current comparison makes essentially the same distinction: Shopify is stronger for connected ecommerce + POS, while Square is particularly attractive for smaller businesses starting with in-person sales. Shopify

squareup.com

3. Lightspeed — probably overkill initially

Lightspeed becomes interesting if your operation gets more complicated: multiple locations, purchasing, vendors, detailed inventory management, etc.

But for a small merch operation, I'd hesitate to introduce that complexity unless you actually need it. Current pricing starts around $89/month, and its ecommerce/POS relationship isn't quite as natively unified as Shopify's. Shopify

What I'd choose

If I were setting up your business today:

Shopify → Shopify POS → Shopify Payments → Shopify online store

I'd start relatively lean and add POS hardware as the event volume requires it.

The bigger question isn't really "Which POS?" It's how complicated your merch operation is going to become. If you tell me roughly:

• annual/expected online sales
• annual/expected live-event sales
• number of SKUs/variants
• how many events you do per month
• whether you manufacture/print yourselves or use a fulfillment/print partner
• whether you need barcode scanning
• whether multiple people will be selling simultaneously

…I can give you a Shopify vs Square vs Lightspeed recommendation specifically for your operation, including likely monthly costs and the event setup I'd use.

…I can give you a Shopify vs Square vs Lightspeed recommendation specifically for your operation, including likely monthly costs and the event setup I'd use.

Yes. For a small merch brand that sells both online and at live events/pop-ups, I’d focus on platforms where the same product catalog, inventory, customer data, and orders work across the website and the event POS.

My shortlist would be:

1. Shopify — probably where I'd start

Shopify is particularly attractive if ecommerce is an important part of the business and events are another sales channel. Its POS is designed to unify online and in-person selling, and basic POS is included with the paid Shopify plans. Shopify specifically supports in-person selling at pop-ups and events. Shopify Shopify

For a small team, the current Grow plan is $105/month and includes unlimited POS logins; POS Pro is an additional $89/month per location if you need advanced staff, inventory, customer and omnichannel features. Shopify

Why I like it for custom merch:

• One product/SKU inventory across web + events
• Excellent ecommerce storefront
• Easy to take an iPad/phone to a pop-up
• Good barcode/SKU workflows
• Customer/order history follows the customer
• Huge ecosystem if you eventually need custom functionality
• Good foundation if your online business becomes much larger than your event business

The important caveat: you probably don't need POS Pro initially if you're primarily doing temporary events rather than operating a permanent retail store.

2. Square — best if you want simplicity

Square is compelling if your priority is "we need to show up at an event, plug in a reader, sell stuff, and go home."

Square's retail system has inventory, SKUs, barcode support, customer profiles, online selling, shipping, discounts, gift cards, etc. Its free tier has $0/month software cost, with paid Retail plans adding more sophisticated inventory functionality. Square Square

Square also explicitly supports syncing its catalog/inventory with Shopify through its Thrive integration, although I'd generally rather choose one ecosystem as your source of truth than build a hybrid unnecessarily. Square

I'd choose Square if:

• Events are a major portion of your revenue
• Your website is relatively simple
• You want the lowest upfront software cost
• You don't want to spend much time administering the system

3. Lightspeed — worth considering if inventory gets complicated

Lightspeed is much more retail/inventory-oriented. Its retail offering includes things like purchase orders, inventory management, integrated payments and ecommerce. Its current Basic plan starts at $89/month. Lightspeed

I'd consider it if you're going to have lots of SKUs, variants, inventory purchasing, multiple locations, wholesale, or more sophisticated retail reporting.

For a small merch team doing markets and concerts, though, I suspect Shopify or Square would give you a better simplicity-to-capability ratio.

What I'd actually do in your shoes

Start by comparing Shopify vs. Square.

I'd lean Shopify if your vision is:

"We're building a merch brand that happens to sell at events."

I'd lean Square if it's:

"We're an event-based merch operation that also needs a web store."

That's the key distinction.

Also, don't just compare monthly POS prices. For your business, I'd test these five workflows before committing:

1. Create a new shirt with 5 sizes + 3 colors
2. Sell 20 units at an event and see whether online inventory immediately reflects it
3. Process a return from an event purchase
4. Look up a customer's previous online purchase at the event
5. Run an event-specific sales report showing units, revenue, discounts, taxes and payment fees

If a system makes those five things painless, it's probably the right system.

My initial ranking for you: Shopify 9/10, Square 8.5/10, Lightspeed 7/10.

If you tell me roughly annual sales, number of events per month, number of SKUs, whether you already have a website, and whether you sell made-to-order/customized items, I can narrow this down considerably and give you a recommended setup—including the POS hardware I'd use.

My shortlist

🥇 I'd start with Shopify

The big advantage for custom merch is that your event sales and website can share one product catalog, inventory, customer database, and order history. Shopify specifically supports selling at pop-ups/events, while its POS keeps in-person and online inventory connected. Shopify Shopify

That becomes particularly useful if you're doing things like:

• 20–100+ merch SKUs with sizes/colors
• Different inventory allocations for different events
• Limited-edition drops
• Preorders at an event that you fulfill later
• Customers buying at an event and then ordering again online
• QR codes at events that send people to your online store
• Multiple people working the merch table
• Eventually selling through Instagram, marketplaces, or other channels

Shopify's current Grow plan is $105/month and includes unlimited POS logins; the more advanced POS Pro functionality is an additional $89/month per location. Shopify

shopify.com

🥈 Square is the one I'd seriously test against it

If your business is primarily live events and the website is secondary, Square may actually be the better choice.

Square is particularly attractive for a small team because you can start cheaply, use phones for Tap to Pay, and have in-person and online sales/inventory connected. Its retail system also supports bulk inventory, purchase orders, transfers, COGS, and real-time inventory across channels. Square Square

Square's online store also supports shipping, pickup, discounts, bundles, subscriptions, abandoned-cart emails, and other ecommerce functionality. Square

squareup.com

The deciding question

I'd use this rule:

Choose Shopify if:

"We are building a merch brand that happens to sell at events."

Choose Square if:

"We are an event merch operation that happens to have an online store."

For most custom merch brands, I'd lean Shopify because ecommerce, marketing, product drops, customer retention, and integrations tend to become more important as you grow.

One important wrinkle: if by "custom merch" you mean customers place highly customized orders at the event (e.g., choose garment + artwork + personalization and you produce/fulfill it afterward), I'd evaluate the platforms differently because the customization/order workflow becomes a major consideration.

If you tell me roughly (1) annual sales, (2) number of SKUs, (3) how many live events/month, (4) whether you manufacture yourselves or use a printer/fulfillment partner, and (5) whether you already have a website, I can give you a much more specific Shopify vs Square vs Lightspeed recommendation, including the likely monthly cost.

For a small team selling custom merch at live events and online, I’d focus less on a traditional retail POS and more on omnichannel commerce: one inventory system, one customer database, one product catalog, and fast mobile checkout at events.

My shortlist would be:

My likely recommendation for your situation

Start with Shopify + Shopify POS if:

• your website is a major sales channel
• you sell limited drops, collections, or artist/team/event merch
• you need inventory to stay accurate between online and a booth
• you want to grow into email marketing, customer tracking, wholesale, etc.

Start with Square if:

• most revenue happens at live events
• you need something a couple people can learn in an hour
• you do lots of one-day setups (festivals, concerts, markets)
• your online store is secondary

fitsmallbusiness.com

Features I’d make sure the platform handles well

For custom merch, these matter more than generic POS features:

• Variant inventory: “Black hoodie / XL” vs “Black hoodie / Medium”
• Barcode scanning: pre-label products before events
• Mobile checkout: phone/tablet-based selling in a booth
• Offline mode: events often have poor Wi-Fi
• Multiple sales channels: website + Instagram/TikTok + events
• Customer capture: collect emails at shows
• Bundles: shirts + posters + signed items
• Preorders: sell at an event, ship later
• Tax handling by location: especially if you travel

A setup I see working well for merch teams

• Shopify online store
• Shopify POS with 1–3 mobile readers/tablets
• Barcode labels on every item
• Inventory counted before and after each event
• Email/SMS capture at checkout
• Event-specific discount codes or collections

A few questions would change the recommendation:

1. Are you selling artist/band/team merch, your own brand, or custom orders for clients?
2. Roughly how many SKUs do you carry (20, 200, 2,000+)?
3. Are live events your main revenue source, or is online bigger?

For a small team selling custom merch both at live events and online, I’d put Shopify + Shopify POS at the top of the shortlist.

The key is that you want one product catalog, one inventory count, one customer database, and one reporting system across your website and every event—not a POS bolted onto an ecommerce store.

My shortlist

1. Shopify + Shopify POS — my first choice

Shopify is particularly well suited if your online store is going to be an important part of the business.

Shopify POS syncs products, inventory, orders and customer information between your online store and physical sales. Its POS is explicitly designed for pop-ups, markets and other mobile selling situations, and you can use Tap to Pay or dedicated hardware at events. Shopify Shopify Help Center

That's a nice fit for merch because you might have:

• 20 T-shirts with different sizes/colors
• hoodies
• hats
• limited-edition event items
• bundles
• custom/personalized products
• inventory split between your warehouse, van and event

A sale at Friday night's show can immediately reduce the inventory available on your website.

The big advantage: Shopify is fundamentally an ecommerce platform that also has a very capable POS, rather than a POS company that happens to offer an online store. That's the direction I'd lean for a merch business. Shopify

2. Square — very compelling alternative

Square is what I'd investigate if you're more event/POS-heavy and want to keep costs and complexity down.

Square has a free POS tier, integrated payments, mobile hardware, inventory, and Square Online for ecommerce. Its retail system can also handle things like barcode scanning, exchanges and inventory management. Square

So, for example, if your business is:

"We go to 30 concerts/festivals a year, sell merch from a booth, and have a relatively simple online shop."

I'd seriously consider Square.

If it's:

"Our website is the core business, and events are an important additional sales channel."

I'd choose Shopify.

3. Lightspeed

Lightspeed becomes more interesting if you expect a much larger SKU count, multiple permanent locations, complicated inventory, purchasing, or sophisticated retail reporting.

For a small merch team, though, I suspect you'd be paying for capabilities you don't need yet. Current comparisons also tend to position Lightspeed toward more complex/established retail operations. Shopify Stash

What I'd actually do

I'd narrow it to:

🥇 Shopify + Shopify POS
🥈 Square + Square Online

And I'd make the decision based on where you expect the business to go.

Choose Shopify if:

• Online sales are important or expected to grow substantially
• You want a strong branded ecommerce site
• You sell through social/other online channels
• You have lots of product variants
• You want customers to be able to buy online after discovering you at an event
• You may eventually have multiple event teams/locations

Choose Square if:

• Most revenue currently happens at events
• You want the simplest possible setup
• You want to minimize monthly software costs
• Your online store is relatively straightforward
• You don't need Shopify's broader ecommerce ecosystem

One particularly useful Shopify feature for merch is "buy in store, ship to customer"—someone can see that you've sold out of a particular size at an event, pay you there, and have the item shipped later. Shopify also supports online-to-in-person returns/exchanges and real-time inventory across locations. Shopify

If you tell me roughly (1) annual online sales, (2) number of live events/month, (3) number of SKUs/variants, (4) how many people will operate the POS, and (5) whether you already have a website, I can give you a much more specific Shopify vs Square recommendation, including the likely monthly cost and hardware setup.

I'd seriously consider Square.

If it's:

"Our website is the core business, and events are an important additional sales channel."

My shortlist

Why I'd lean Shopify

Your business has a particularly good use case for one inventory system serving both ecommerce and temporary event locations.

With Shopify POS, you can have your website and each event treated as selling locations, with inventory updating as merchandise sells. Shopify specifically supports pop-ups, markets and events, and its POS can sync orders and inventory with the online store. Shopify Shopify Help Center

That gives you a workflow like:

Website → Shopify inventory ← Event POS

So if you have 100 hoodies and sell 30 online before a show, your event team sees the remaining inventory. Conversely, if you sell 25 at the event, the online quantity updates. Shopify also supports multiple locations, customer profiles, returns, buy-online/pickup, and other omnichannel workflows. Shopify Shopify

For merch specifically, I'd also value the ecommerce side more than I would with a typical local retailer. Your website is likely to be an important sales channel, and Shopify gives you a mature ecommerce platform rather than treating the website as an add-on to the POS.

When I'd choose Square instead

I'd seriously consider Square if your priority is:

• Getting started cheaply
• Very easy event/pop-up checkout
• A small catalog
• A relatively simple online store
• Keeping the technology/operations extremely straightforward

Square's online store and POS share inventory, orders and customer information, and Square offers a free POS plan with no monthly software fee. Square Square

The tradeoff is that Shopify is generally the stronger ecommerce/omnichannel platform, while Square is particularly attractive if your business is primarily in-person and ecommerce is secondary. A 2026 comparison from Shopify similarly characterizes Shopify as stronger for integrated omnichannel selling and Square as particularly suitable for very small retailers and pop-ups. Shopify

One important question for your business

The choice gets much easier if I know how your merch operation actually works.

For example, there's a big difference between:

15–30 SKUs, mostly T-shirts/hoodies, 5–10 events a year

and

200+ SKUs, multiple artists/brands, different merch allocations per event, preorder/drop fulfillment, several people selling simultaneously.

If you tell me roughly (1) number of SKUs, (2) online sales vs. event sales %, (3) how many events/month, (4) whether you do preorders/custom orders, and (5) approximate annual revenue, I can give you a Shopify vs Square vs Lightspeed comparison specifically for your operation, including likely costs and the POS hardware I'd use at events.

For a small merch business selling at live events + online, I’d narrow the field to Shopify, Square, and Lightspeed. My default recommendation would be Shopify, unless your event selling is much more important than ecommerce.

My shortlist

1. Shopify — my first choice

Shopify is particularly compelling because POS and ecommerce are the same underlying system, rather than two systems that have to be connected. Inventory, orders, customer information and products can be managed from the same back office. Shopify explicitly supports mobile selling at pop-ups/events and real-time inventory across online and physical locations. Shopify Shopify

For custom merch, I'd especially like it if you have:

• Lots of T-shirt/hoodie sizes and colors
• Limited-edition drops
• Customers who see something at an event and later buy online
• QR codes at events that send people directly to your online store
• Multiple events happening close together
• A desire to build a real ecommerce brand rather than just have an online catalog

The big advantage is that you don't end up reconciling "event inventory" against "website inventory" manually.

shopify.com

2. Square — best if events are the center of the business

I'd seriously consider Square if you're primarily traveling to events and selling merch there, with ecommerce being secondary.

Square has strong event-friendly features, including mobile payments and offline payment capability, while Square Online can share products, orders and inventory with the physical POS. Its retail system also supports variants, barcode scanning, stock counts, purchase orders and real-time inventory syncing. Square Square

That's attractive for a small team because you can start relatively simply without building a sophisticated ecommerce operation.

squareup.com

3. Lightspeed — consider it if your inventory gets complicated

Lightspeed is the one I'd investigate if you're going to have a lot of SKUs, variants, vendors, locations, purchasing and inventory management.

Its POS and ecommerce products synchronize inventory and orders, and its retail system is particularly strong around inventory management. Lightspeed X-Series Support Lightspeed

But for a small merch operation, I'd probably not start here unless you already know you have complex inventory requirements. It can be more system than you need.

lightspeedhq.com

What I'd choose for your situation

If you're building a merch brand:
→ Shopify

If you're essentially an event vendor that also happens to sell online:
→ Square

If you're becoming a substantial retailer with complicated inventory:
→ Lightspeed

One important thing I'd evaluate before choosing is how your live events actually work. For example, if you have 2–4 people selling simultaneously, unreliable Wi-Fi, 100+ SKUs, cash + cards, multiple booths, event-specific pricing, and merchandise that is also available online, the POS requirements get much more specific.

If you tell me roughly (1) annual sales, (2) number of SKUs/variants, (3) number of events per month, (4) whether you need offline payments, and (5) whether your existing website is Shopify/WooCommerce/etc., I can give you a much more specific Shopify vs Square recommendation, including likely monthly costs and hardware.

For a small team selling custom merch at live events + online, I’d focus less on “retail POS” and more on omnichannel inventory: one catalog, one inventory count, easy mobile checkout, customer capture, and a website that can grow with you.

The platforms I’d put at the top of your shortlist:

Shopify Stash## My likely recommendation for your use case

If you are building a merch brand:

Shopify + Shopify POS

This is usually the strongest fit for:

• Band/artist merch
• Creator brands
• Apparel drops
• Limited editions
• Pre-orders
• Online + touring/event sales

Your workflow becomes:

Website order → inventory decreases → event sales use same inventory → customer data stays together

That unified inventory/customer view is the big advantage. Shopify

If you mostly sell at events right now:

Square + Square Online

I’d choose this if:

• You do lots of one-off events
• Your catalog is small (for example 20–100 SKUs)
• You need to be set up quickly
• Multiple people need to run checkout without much training

Square is widely used by small mobile sellers because it is simple and has low startup friction. Fit Small Business

Merch-specific features I would require

Whatever you choose, make sure it handles:

• Product variants (shirt → size → color)
• Barcode labels/scanners
• Offline checkout (events often have bad Wi-Fi)
• Inventory transfers (“move 50 hoodies to the festival box”)
• Bundles (“album + shirt package”)
• Discount codes
• Customer email/SMS capture
• Returns/exchanges across channels
• Multiple tax locations if you travel
• Staff permissions

A simple decision rule

• 70%+ online sales: Shopify POS
• 70%+ live events/pop-ups: Square
• Growing into a warehouse + multiple sellers/locations: Lightspeed or Shopify with stronger inventory apps
• Touring merch operation: Shopify POS + good inventory workflow is probably where I’d start

A few questions would change the recommendation:

1. Are you selling your own branded merch (artists/creators/company) or custom merch for clients?
2. Roughly how many SKUs do you carry (20, 200, 2,000+)?
3. Do you need to print/fulfill orders yourselves, or just sell finished inventory?

For a small team selling custom merch both at live events and online, I’d put Shopify at the top of the shortlist.

The key is to avoid having “an ecommerce system” and “a separate event POS” that you have to reconcile later. You want one product catalog, one inventory count, one customer/order database, and one reporting system.

My shortlist

1. shopify.com — my first choice

This is particularly well suited to your model because Shopify POS is designed for pop-ups, markets, trade shows and mobile selling, while the ecommerce side lives in the same system. Sales made at an event can update your online inventory automatically. Shopify Shopify

For custom merch, I'd especially like it for:

• Variants — shirt style × size × color, etc.
• Real-time inventory between your website and events.
• Mobile checkout at events.
• Customer capture at the event so an in-person buyer can become an online customer.
• Buy online / ship later if you run out of a particular item at an event.
• QR codes that can send someone from a physical product to its online product page.
• Centralized reporting across online and event sales. Shopify

Shopify also supports mobile POS hardware and payment methods suitable for selling away from a permanent store. Shopify

The big advantage: I'd rather have Shopify be the system of record for your catalog and inventory than bolt a POS onto your ecommerce site.

2. squareup.com — worth a serious look

Square is probably the one I'd compare directly against Shopify.

It's particularly attractive if live events are a huge percentage of your business and you want the easiest possible POS experience. Square Online integrates with Square POS, with inventory and customer information shared across channels. Square

I'd lean Square if:

• You're a very small team.
• Events are more important than sophisticated ecommerce.
• You want a relatively straightforward POS setup.
• You don't need a highly customized online storefront.
• You want to keep initial software costs/complexity down.

Square's retail system also supports real-time inventory across locations and sales channels. Square

3. lightspeedhq.com

I'd investigate Lightspeed if your merch operation starts becoming inventory-heavy—lots of SKUs, purchasing, multiple locations, more complicated stock management, etc.

For a small merch team just getting the online + event operation working, though, I think Shopify or Square is likely to be less cumbersome.

What I'd choose for your situation

Shopify + Shopify POS if your goal is to build a real merch business where the website eventually becomes an important sales channel.

Square + Square Online if your priority is “we need to show up at an event, plug in the reader, sell stuff, and get out of there.”

One thing I'd pay particular attention to before choosing: how you handle custom/pre-order merchandise. If you sometimes sell designs at an event and then manufacture/fulfill them afterward, that can change which platform/workflow makes the most sense.

If you tell me roughly (1) annual sales, (2) how many events per year, (3) number of SKUs/variants, (4) whether you manufacture yourselves or use a print/fulfillment company, and (5) whether you already have a website, I can narrow this down to a specific recommendation and the likely monthly cost.

For a small team selling custom merch both at live events and online, I’d put Shopify at the top of the shortlist, with Square as the main alternative.

The key is to choose a system where the online store, event POS, inventory, customer data, and orders all share one catalog. That avoids the nightmare of selling 20 shirts at an event and then discovering your website still thinks you have those 20 shirts in stock.

My shortlist

1. Shopify — my first choice

Shopify is particularly compelling for merch because ecommerce is its core strength, while Shopify POS is designed to work at pop-ups, markets, trade shows and other mobile selling situations. Inventory, customer profiles and orders can stay synchronized between online and physical sales. www.shopify.com

For your model, I'd specifically like:

• One product catalog for the website and events
• Real-time inventory across event locations and online
• Mobile POS for events
• Customer capture at checkout
• Online ordering after someone sees your merch at an event
• Buy-online/pickup and shipping capabilities
• Good integrations for email marketing, fulfillment, accounting, etc.
• Room to grow if the merch operation gets substantially bigger

Shopify also supports centralized inventory across warehouses, retail locations and temporary pop-ups. www.shopify.com

Shopify POS

2. Square — worth serious consideration

Square is probably the one I'd demo alongside Shopify. Square is very good if your priority is getting a small team selling at events quickly without a lot of operational complexity.

Square for Retail can synchronize inventory across physical and online channels, and Square Online provides the ecommerce side. squareup.com

I'd lean Square if:

• Most of your revenue currently happens at events
• Your online store is relatively straightforward
• You want very simple POS hardware
• You don't need Shopify's enormous ecommerce/app ecosystem
• Keeping software costs down is important

Square for Retail

Where I'd land

If you told me "We're a 2–10 person team, we make/sell custom shirts, hats, hoodies, etc., do concerts/festivals/pop-ups, and also have an online store", I'd start with:

🥇 Shopify + Shopify POS
🥈 Square for Retail + Square Online
🥉 Lightspeed

The deciding factor is where you expect the business to go. If ecommerce, social selling, email marketing, drops, preorders and a growing online customer base are important, I'd choose Shopify. If you're primarily an event seller that happens to have an online shop, I'd look harder at Square.

One important wrinkle for custom merch: I'd also evaluate how each handles variants (size/color), bundles, custom products, preorder inventory, event-specific stock allocations, barcode scanning, returns, and potentially print-on-demand/fulfillment integrations. Those details can matter more than the headline POS features.

If you tell me roughly (1) number of events/month, (2) online sales vs event sales, (3) number of SKUs/variants, (4) whether you manufacture yourselves or use a printer/fulfiller, and (5) your approximate monthly revenue, I can narrow this down to the best 2–3 setups and what I'd actually buy for the team.

For a small merch team selling custom products both at live events and online, I’d narrow it to Shopify vs. Square, with Shopify probably the better long-term fit.

My pick: Shopify

Shopify

For your particular model, I'd lean Shopify + Shopify POS. The big advantage is that the ecommerce store and POS are actually one commerce system: products, variants, customers, orders and inventory are synchronized between your website and physical sales. Shopify specifically supports selling through pop-ups and other temporary locations. www.shopify.com

That's particularly useful for merch because you might have:

• 20 T-shirt designs × 5 sizes × 4 colors
• limited-edition event merch
• different inventory allocated to different events
• online preorders
• products that are available online but not at an event
• event-specific pricing or bundles
• inventory that needs to decrement immediately when someone buys at a booth

Shopify lets you manage inventory by location, and sales at one location update that location's stock. help.shopify.com

It also gives you considerably more room to build out the online side as the merch business grows.

The dark horse: Square

Square

If most of your revenue is currently coming from events and the website is relatively simple, I'd seriously consider Square.

Square's POS is particularly attractive for a small team because you can get started cheaply, and Square Online integrates directly with the POS, including inventory and customer information. squareup.com

Square's free online plan currently has no monthly fee, with online processing listed at 2.9% + 30¢ per transaction. squareup.com

So I'd frame the decision this way:

Choose Shopify if:

• Online sales are strategically important
• You want a really good branded merch store
• You expect lots of SKUs/variants
• You want email marketing, apps, subscriptions, drops, etc.
• You expect the business to grow substantially
• You want one system to become the backbone of the business

Choose Square if:

• Events/pop-ups are the core business
• You want the simplest possible POS
• You want to minimize monthly software costs
• Your online store is more of a supporting channel
• You don't need sophisticated ecommerce functionality yet

One thing I'd not do

I wouldn't start with WooCommerce + a separate POS unless you have a strong reason to own/control the website technically. You can make it work, but for a small team the integration and maintenance burden isn't worth it when Shopify and Square already solve the online + physical problem natively. Current comparisons also put Shopify and Square among the strongest small-business options, with Shopify particularly strong for integrated ecommerce/POS and Square for inexpensive omnichannel retail. fitsmallbusiness.com

If you tell me roughly (1) annual sales, (2) how many SKUs/variants you have, (3) how many live events per month, and (4) whether you're already using Shopify/Square/another website, I can give you a much more specific recommendation—including what I'd use for the actual event setup and the likely monthly/payment costs.

For a small team selling custom merch at live events + online, I would focus less on “the best POS” and more on one source of truth for inventory, variants, customers, and orders. Merch businesses usually get hurt by selling the last hoodie at a show while the website still thinks it is available.

My shortlist would be:

Shopify Square Lightspeed### My recommendation by business stage

If you are building a merch brand:

Choose Shopify + Shopify POS.

It is usually the strongest fit if you:

• Sell collections online
• Run preorders/drops
• Have lots of SKUs (shirt sizes, colors, designs)
• Want customer accounts, email marketing, abandoned-cart recovery, etc.
• Expect online sales to become a major channel

Shopify POS is designed to keep in-person and online sales connected, including pop-ups and events. Shopify Shopify

If you mostly sell at shows, festivals, and markets:

Choose Square.

It is attractive when your workflow is:

• Load a van
• Set up a booth
• Take hundreds of quick transactions
• Go home and reconcile sales

Square is popular with small mobile sellers because it is quick to deploy and its POS and online tools are tightly integrated. Square

If you have thousands of units and operational complexity:

Look at Lightspeed.

It becomes more compelling when you need:

• Better inventory purchasing
• Multiple warehouses/locations
• More advanced retail reporting
• Larger staff workflows

Lightspeed## For a custom merch team, I would also prioritize:

• Barcode scanning (especially for events)
• Offline selling if venues have poor Wi-Fi
• Variant management (size/color/design)
• Easy inventory counts after events
• Customer capture at checkout (email/SMS)
• Returns/exchanges across channels
• Ability to create bundles (shirt + hat + sticker pack)

A practical setup many small merch companies use:

• Shopify as the “brain”
• Shopify POS on iPads/phones at events
• Barcode labels on every item
• Card readers + a backup hotspot
• A simple inventory routine after each event

If you tell me:

1. roughly how many events you do per year,
2. monthly online sales volume,
3. number of SKUs (designs × sizes × colors), and
4. whether you print/fulfill yourselves or use a fulfillment partner,

I can narrow this to a specific recommendation.

For a small team selling custom merch both at live events and online, I’d put Shopify and Square at the top of the shortlist, with the choice depending mainly on whether your business is ecommerce-first or event/POS-first.

My shortlist

1. Shopify — my first choice

shopify.com

I'd lean Shopify if your website and online sales are an important part of the business.

The big advantage is that your online store and event POS are essentially the same commerce system. Inventory, products, variants, customers and orders stay synchronized across your website and physical selling locations. Shopify specifically supports mobile/event selling and temporary pop-up locations. Shopify Shopify

That's particularly attractive for custom merch because you might have:

• T-shirts in multiple sizes/colors
• Hoodies, hats, posters, etc.
• Limited-edition event merchandise
• Different pricing/promotions at events
• Inventory split between your warehouse, online store and event stock

Shopify can track those variants and locations centrally, and its POS can run on mobile hardware at events. Shopify Shopify

I'd choose Shopify if: you're trying to build a real merch brand rather than simply process transactions.

2. Square — potentially the better starting point

squareup.com

Square is worth serious consideration if live events are the heart of the business and you want something that a small team can get running quickly.

Square's POS and online store share inventory, orders and customer information, and Square supports selling online, pickup, shipping and delivery. Square Square

It's also designed around the kind of quick retail transaction you'd encounter at a concert, festival, market, pop-up, etc.

The tradeoff is that I generally prefer Shopify's ecommerce ecosystem and storefront capabilities if the online side is going to become substantial.

3. Lightspeed — keep it in the second round

lightspeedhq.com

I'd look at Lightspeed if you're going to have a large SKU count, complicated inventory, multiple locations, purchasing/warehouse requirements, or eventually a more sophisticated retail operation.

For a small merch team, though, I wouldn't start there unless you already know you need its deeper retail functionality.

What I'd do in your situation

I'd narrow it to:

Shopify POS vs. Square Retail.

And I'd make the decision based on this question:

Is the website going to be the center of the business, or are live events going to be the center?

• Website + social + online orders + events → Shopify
• Events/pop-ups + occasional online orders → Square
• Complex inventory/multiple locations → consider Lightspeed

One other thing I'd pay particular attention to: how each handles inventory allocated to an event. For example, if you take 150 shirts to a festival, sell 87, and bring 63 home, you want that process to be painless and have the remaining 63 immediately available to your online store again. Shopify's multi-location inventory is particularly well suited to this model. Shopify Shopify

If you tell me roughly (1) annual sales, (2) number of live events per year, (3) number of SKUs/variants, (4) whether you already have a website, and (5) how many people will run the POS, I can narrow this down to the best 2–3 setups and compare the actual monthly + payment costs and event hardware.

Square's POS and online store share inventory, orders and customer information, and Square supports selling online, pickup, shipping and delivery. Square Square

It's also designed around the kind of quick retail transaction you'd encounter at a concert, festival, market, pop-up, etc.

The tradeoff is that I generally prefer Shopify's ecommerce ecosystem and storefront capabilities if the online side is going to become substantial.

3. Lightspeed — keep it in the second round

I'd look at Lightspeed if you're going to have a large SKU count, complicated inventory, multiple locations, purchasing/warehouse requirements, or eventually a more sophisticated retail operation.

Shopify's multi-location inventory is particularly well suited to this model.

Yes. For a small merch business selling both at live events and online, I’d narrow it to Shopify vs. Square, with Lightspeed as the “we’re getting more sophisticated” option.

My shortlist

Shopify is particularly compelling because its POS and ecommerce are designed as one system, with inventory and customer data synchronized between channels. Current comparisons also rate it especially highly for omnichannel/ecommerce businesses. www.shopify.comwww.shopify.com

Why I'd lean Shopify for custom merch

Your business has an unusual combination of requirements:

Online

• Product variants: size/color/design
• Limited-edition drops
• Discount codes
• Shipping
• Customer accounts
• Email/marketing integrations

At events

• Fast checkout
• Tap/chip payments
• Phone/tablet-based selling
• Potentially multiple sellers simultaneously
• Spotty Wi-Fi/offline capability
• Inventory needs to come out of the same pool as online inventory

That last point is the big one. You don't want someone buying the last 2XL at an event while your website still says it's available.

Shopify is very good at making the website and POS two doors into the same inventory/order system. POS Lite is included with Shopify plans, while POS Pro adds more advanced retail capabilities and is currently $89/month/location. www.shopify.comwww.shopify.com

When I'd choose Square instead

I'd seriously consider Square if most of your revenue is at events and the website is relatively simple.

Square has a free POS tier, inexpensive hardware, mobile selling, inventory and an online store. It also has good offline capabilities, which can matter at festivals, venues and pop-ups where connectivity isn't dependable. fitsmallbusiness.com

So:

70%+ events / simple online store → Square

50/50 or growing ecommerce → Shopify

Complex inventory / multiple locations / lots of SKUs → Lightspeed

One thing I'd pay particular attention to

For live events, don't just demo the software sitting in an office. Actually simulate an event.

I'd want to see:

1. Two people selling simultaneously from phones/tablets.
2. A customer buys the last item at the event.
3. Someone immediately tries to buy that item online.
4. Wi-Fi goes down.
5. Customer wants to exchange something bought online at an event.
6. You create a new merch design and its size/color variants.
7. You need to count remaining inventory after the event.
8. You need to know “How much did we actually make at Event X?”

Those workflows will tell you far more than a generic POS demo.

My starting recommendation: I'd demo Shopify POS first and Square second. For a small custom-merch operation, I suspect Shopify will give you the best long-term combination of ecommerce, event selling and inventory without requiring you to stitch several systems together. www.shopify.com

If you tell me roughly (a) annual sales, (b) number of events/month, (c) number of SKUs, (d) whether you sell mostly apparel, and (e) whether you need QuickBooks, I can narrow this down to the best 2–3 setups and estimate the monthly + per-transaction cost for each.

Yes. For a small merch business selling at live events + online, I’d narrow the field pretty quickly to Shopify, Square, and Lightspeed.

My shortlist

1. Shopify — probably where I'd start

For your particular model, Shopify is my first choice.

Shopify POS is designed to keep your physical and online sales in one system, with inventory syncing across locations and sales channels in real time. It also supports mobile POS hardware, customer profiles, returns/exchanges, QR codes that can send an event customer to an online purchase, and ship-from-store workflows. www.shopify.comwww.lightspeedhq.com

That's particularly useful for merch at events:

Example: You bring 200 shirts to a festival. You sell 130 through the POS. Shopify automatically knows you have 70 left for your website. Someone at the event wants a size/color you didn't bring—you can potentially send them to your online store instead of losing the sale.

The bigger advantage is that Shopify is extremely strong on the ecommerce side. If online sales eventually become a major part of the business, you won't outgrow the storefront nearly as quickly.

I'd choose Shopify if:

• Online sales are important or expected to grow
• You have lots of apparel variations (size/color)
• You want a polished branded website
• You sell at lots of temporary events/pop-ups
• You want customers' online and in-person purchases tied together
• You may eventually add wholesale, marketplaces, email marketing, etc.

2. Square — the one I'd test first for simplicity

Square is particularly attractive if your priority is "we need to show up at an event, take payments, and not have this become a technology project."

Square's catalog is shared between its POS and website, and inventory can update from POS and online sales. It also supports mobile selling and offline payments, which is a big deal at live events where Wi-Fi can be questionable. squareup.com

Square also has online-store functionality, shipping, pickup, customer accounts, discounts, and inventory tools. squareup.com

I'd choose Square if:

• You're a very small team
• Most revenue initially comes from events
• You want minimal setup/administration
• Your ecommerce needs are relatively straightforward
• Keeping software costs down matters
• You don't need a highly sophisticated ecommerce operation

One interesting possibility is starting with Square and moving to Shopify later, but I'd avoid designing a complicated two-system setup unless there's a specific reason.

3. Lightspeed — powerful, but probably more than you need initially

Lightspeed is worth considering if your merchandise operation gets inventory-heavy. It has strong support for variants, composite/bundled products, purchase orders, stock transfers, receiving, barcode labels, multiple inventory locations and an ecommerce storefront. www.lightspeedhq.com

I'd lean toward it if you're going to have a lot of SKUs, significant inventory, multiple locations, or more sophisticated purchasing/retail workflows.

For a small team doing pop-ups and online sales, though, I'd probably rather spend the operational complexity budget on the business itself.

What I'd actually do in your shoes

Start by demoing Shopify POS and Square side-by-side.

The decision isn't really about which has the most features. It's about where you want your "system of record" to live:

Shopify:
Online store ←→ Shopify ←→ Event POS

Square:
Online store ←→ Square ←→ Event POS

Both can give you the important thing: one product catalog + one inventory picture + one customer/order history.

And for custom merch, I'd specifically test these five workflows before signing up:

1. Sell a shirt at an event → inventory immediately decreases.
2. Sell that same shirt online → event inventory reflects the online sale.
3. Customer wants an item you don't have at the event → can you easily place/send them an online order?
4. Customer returns an online purchase at an event → how painless is the return?
5. You have 30 shirts × 5 sizes × 4 colors → how easy is it to manage the variants?

If ecommerce is going to be a serious growth channel, I'd pick Shopify.

If live events are the core business and online is mainly a complementary storefront, I'd give Square a very serious look.

If you tell me roughly (a) annual sales, (b) number of events/month, (c) number of merch SKUs/variants, (d) whether you manufacture the merch yourselves or use a decorator/fulfillment company, and (e) whether you already have a website, I can narrow this down to the best 1–2 setups and estimated monthly costs for your situation.

For a small merch team selling at live events + online, I’d put Shopify at the top of the shortlist, with Square as the main alternative.

The key is that you want one product catalog, one inventory pool, one customer/order database, and one reporting system—not a POS bolted onto a separate ecommerce site.

My shortlist

1. Shopify — my first choice

For your particular model, Shopify's biggest advantage is that the ecommerce store and POS are actually part of the same commerce system. A sale at a concert/festival/pop-up can reduce the same inventory that is available on your website. Shopify explicitly supports pop-ups, markets and other temporary selling locations, and its POS syncs orders and inventory with the online store. www.shopify.comsquareup.com

That becomes particularly valuable with merch because you'll likely have things like:

• T-shirts by size/color
• Hoodies
• Hats/accessories
• Limited-edition event merch
• Bundles
• Different pricing/promotions
• Products that sell both online and at events

Shopify can handle those variants while keeping inventory synchronized. You can also use mobile POS hardware—or even an iPhone for certain event setups—rather than building a traditional countertop register. www.shopify.com

I'd choose Shopify if: the online side of the business is important and you expect the merch operation to grow.

2. Square — very compelling alternative

Square is worth serious consideration if you're a small team and want to get operational quickly without spending much on software.

Square combines POS, inventory, online selling, payments and customer management, and its inventory can update across in-person and online channels. api.squareup.com

It's particularly attractive if your business is event-first:

Set up table → turn on Square → sell merch → inventory updates → go home.

Square also offers an online store, so you don't necessarily need to maintain a separate ecommerce platform. squareup.com

I'd choose Square if: the majority of your sales happen at events and your website is primarily a straightforward online storefront.

Shopify vs. Square for your use case

I'd frame the decision this way:

Choose Shopify if you think:

"We're building a merch/ecommerce brand that happens to sell at events."

Choose Square if you think:

"We're an event-selling business that also sells merchandise online."

That's the biggest distinction.

Shopify's ecommerce ecosystem is considerably stronger, while Square is exceptionally attractive for straightforward in-person selling and small-business operations. A current 2026 small-business POS comparison likewise puts Square at the top for overall value while identifying Shopify as particularly strong for ecommerce/multichannel selling. fitsmallbusiness.com

One thing I'd pay a lot of attention to

For live events, don't just compare monthly software prices. Test the actual checkout workflow.

You want to know:

1. Can two or three staff members sell simultaneously?
2. Can you use phones/tablets rather than a bulky register?
3. What happens if the venue's Wi-Fi is bad?
4. How quickly can someone check out a customer?
5. Can you easily count/adjust inventory before and after an event?
6. Can you see event-by-event profitability/sales?
7. Can an event-specific location be created so inventory doesn't get confused with your warehouse?
8. Can customers buy something at the event and later shop online using the same customer record?
9. How easy is it to handle returns/exchanges?
10. What are the actual card processing fees for your expected volume?

For a merch operation, those details can matter more than whether the ecommerce site has 50 more features.

If you give me roughly your expected annual sales, number of live events/month, number of SKUs, average transaction size, and whether you're selling merch for yourselves or for artists/brands, I can narrow this down to the 2–3 platforms I'd actually demo and tell you what I'd pick.

For a small team selling custom merch both at live events and online, I’d put Shopify at the top of your shortlist, with Square as the main alternative.

My ranking

1. Shopify — probably where I'd start

Shopify is particularly well suited to the "we have a website, but also show up at a festival/concert/trade show and sell out of the back of a van" model.

Shopify POS is designed for selling at pop-ups and events, while keeping the same products, inventory, customers and orders connected to your online store. www.shopify.com

For merch specifically, the useful pieces are:

• One product catalog for online and events
• Size/color variants with individual SKUs and inventory
• Inventory deducted when you sell something at an event
• Online inventory reflects event sales
• Mobile POS for selling away from a permanent store
• Barcode scanning
• Customer profiles and purchase history
• Discounts, gift cards and promotions
• Online ordering and shipping
• Ability to sell through social channels/marketplaces
• More sophisticated apps if you eventually need custom merch workflows

Shopify specifically supports inventory across locations, which is useful if you think of "Event A," "Event B," "home/warehouse," and "online" as different inventory locations. www.shopify.com

Shopify POS

The downside: Shopify can become more expensive and complicated as you add POS features, apps, payment processing, etc. If you're doing relatively simple transactions, you may be paying for capabilities you don't need.

2. Square — I'd seriously consider this if events are the bigger channel

Square is arguably the easier choice if your business is fundamentally "we sell stuff in person and also have an online store."

Square's catalog and inventory can sync between its POS and online store, and its retail system supports real-time inventory across locations and online. squareup.comsquareup.comwww.shopify.com

It's particularly attractive for live events because Square is very good at the physical transaction itself:

• Fast checkout
• Phone/tablet POS
• Card/contactless payments
• Barcode scanning
• Inventory tracking
• Offline payment capability
• Easy refunds/exchanges
• Customer capture
• Simple hardware

That offline payments capability is worth paying attention to for live events. Square says it can accept payments without Wi-Fi and store transactions until connectivity returns. squareup.comsquareup.comwww.shopify.com

Square for Retail

Square also has ecommerce, so you don't necessarily have to bolt another platform onto it. squareup.com

The downside: I'd choose Shopify if the online side is going to become a major growth engine. Shopify is the more ecommerce-centric ecosystem.

3. Lightspeed — powerful, but probably overkill initially

Lightspeed is worth looking at if you expect lots of SKUs, multiple locations, purchasing, inventory complexity, and a more traditional retail operation.

Its Retail POS and eCom can synchronize inventory and orders. x-series-support.lightspeedhq.com

But for a small merch operation, I'd want a specific reason to choose Lightspeed over Shopify/Square. You're potentially buying into a more sophisticated retail system when what you really need may be "scan shirt → take payment → decrement inventory → make the sale appear online."

Lightspeed Retail

The bigger question for your business

I'd actually choose based on how your events work.

If you're doing something like:

10–50 events/year → bring 100–500 pieces of merch → sell shirts/hats/etc. → go home → replenish → continue selling online

I'd lean Shopify.

If it's more:

Lots of small events → minimal ecommerce → we need a dead-simple card reader/POS → don't want to spend much time administering software

I'd lean Square.

And if you're doing:

Multiple teams/locations → hundreds/thousands of SKUs → serious inventory purchasing → warehouses → complex retail operations

I'd investigate Lightspeed.

One thing I'd prioritize above almost everything else

For your business, inventory synchronization is critical.

You don't want:

Online: 7 black XL shirts
Event POS: 7 black XL shirts
Actual physical inventory: 7 black XL shirts

…and then sell 5 at the event while the website still thinks there are 7.

Both Shopify and Square can keep inventory synchronized across online/in-person channels, which is why I'd start with those two. squareup.comsquareup.comwww.shopify.com

My default recommendation: Shopify + Shopify POS, unless keeping costs and operational simplicity extremely low is the priority—in which case Square deserves a very serious look.

If you tell me roughly (1) annual online sales, (2) number of live events, (3) number of SKUs/variants, (4) whether you need custom-order/take-home-later functionality, and (5) whether you already have a website, I can narrow this down to the best 2–3 setups and compare their likely costs.

For a small merch team selling at live events + online, I’d put Shopify at the top of the shortlist, with Square as the main alternative.

1. Shopify — my first choice

This is particularly well suited to your model because Shopify POS and the online store share the same product catalog, orders, customers, and inventory. Shopify specifically supports selling at pop-ups/events and syncing those sales with your online inventory. www.shopify.com

For custom merch, I'd especially value:

• Variants for size/color/design combinations and individual SKUs.
• Real-time inventory across your online store, event setup, and storage locations.
• Barcode scanning for fast event checkout and stock counts.
• Customer capture at events so an event buyer can become an online customer.
• Buy online / ship later if you run out of a size at an event.
• A large app ecosystem if you eventually need custom-order workflows, print-on-demand, email/SMS marketing, shipping, accounting, etc. www.shopify.com

The big advantage is that you can treat an event booth almost like another store location, rather than having "event sales" and "online sales" as two separate businesses.

2. Square — definitely worth comparing

I'd choose Square if your priority is "we need to show up at an event, plug in the hardware, and sell stuff without a lot of operational complexity."

Square's retail system handles inventory, payments and online selling, with inventory automatically adjusted when items sell. It also supports clothing/apparel particularly well. squareup.com

Square may make more sense if the majority of your revenue is currently at events and ecommerce is secondary.

The decision I'd make

If you're building a merch brand: → Shopify

If you're primarily an event seller that happens to have a web store: → Square

If you have complex wholesale, purchasing, multiple warehouses/locations, or sophisticated retail requirements: → investigate Lightspeed too.

For a small team, I would not start with a complicated POS/ERP stack. The killer feature you want is:

Sell 3 XL black hoodies at an event → inventory immediately becomes 17 → your website shows 17 → someone orders one online → event inventory/back-office inventory reflects the new 16.

That's the core workflow I'd test before choosing anything.

If you tell me roughly (1) number of SKUs, (2) how many events/month, (3) whether you do custom orders at the event, and (4) your approximate annual sales, I can narrow this down to the best 2–3 setups and the likely monthly cost for your team.

For a small merch business selling custom products both at live events and online, I’d put Shopify + Shopify POS at the top of the shortlist.

The key is that you want one product catalog, one inventory count, one customer/order database, and one reporting system rather than bolting a POS onto an ecommerce store.

My shortlist

1. Shopify — probably my pick for you

Shopify is particularly attractive because the ecommerce site and POS are native parts of the same system. Inventory, orders, customers and products can sync between your online store and temporary event/pop-up locations. Shopify explicitly supports mobile selling at pop-ups, markets and other events. www.shopify.com

For merch, I'd particularly value:

• Event POS: take payments from a phone/tablet at festivals, concerts, markets, etc.
• Real-time inventory: sell 10 shirts at an event and your online inventory drops accordingly.
• Variants: size/color combinations are handled as individual inventory items.
• Ship-to-customer: if you're out of a size at an event, you can potentially sell it and ship it later.
• Customer capture: collect email/customer information at checkout.
• Online + social selling: the same catalog can power your website and other sales channels.
• Scalability: you don't have to migrate platforms if the merch operation becomes substantially larger. www.shopify.com

For a merch company, I'd also test the actual event checkout workflow before committing: cellular connectivity, offline behavior, speed of scanning/selecting variants, receipts, tips, refunds, and how quickly a new employee can learn it.

2. Square — worth serious consideration

If your business is more event-heavy than ecommerce-heavy, I'd look closely at Square.

Square's online store and POS can share inventory, orders and customer data, and Square supports both its own ecommerce tools and connections to other ecommerce platforms. squareup.com

The appeal is simplicity and cost. Square is a particularly good choice if you want to say:

"We need to show up at an event with a couple of phones/tablets, take payments, and not have a complicated retail system."

The tradeoff is that Shopify is the stronger ecommerce/commerce platform overall, in my view. If your website is going to become a significant sales channel, I'd lean Shopify.

3. Lightspeed

I'd consider Lightspeed if you expect the business to become a more inventory-intensive retail operation—multiple locations, lots of SKUs, purchasing, sophisticated inventory controls, etc.

For a small team primarily doing custom merch + events + online, though, I suspect it could be more system than you need.

What I'd choose

I'd narrow it to:

Shopify if:

Online sales are important and you want the business to grow around ecommerce.

Square if:

Live events are the core business and the website is relatively simple.

Lightspeed if:

Inventory/retail operations are going to become unusually complex.

For your particular description, I'd start with Shopify. It gives you the cleanest "one business, one inventory, two channels" setup. Shopify's current POS supports event/pop-up selling and keeps POS and ecommerce inventory synchronized. www.shopify.com

One important question would change my recommendation quite a bit: are you selling your own branded merch directly to consumers, or are you producing custom merch for clients/events (e.g. a band, company, festival, or sports team)? The latter has some very different workflow requirements.

Yes. For a small merch team selling at live events + online, I’d narrow the field to Shopify, Square, and possibly Lightspeed—but I’d start by comparing Shopify vs. Square.

My quick take

1. Shopify — my first choice

I'd lean Shopify if your online business is important and you expect it to grow.

Shopify POS is designed specifically to keep online, pop-up/event, and other sales channels synchronized. Inventory, orders, customers, products, and payments live in one back office. It also supports mobile selling at events, product variants, barcode scanning, customer profiles, and multi-location inventory. www.shopify.comsquareup.com

For custom merch, that's particularly attractive because you might have:

• T-shirts → size × color
• Hoodies → size × color
• Hats, posters, stickers, etc.
• Limited-edition event merchandise
• Different inventory physically traveling to different events
• Online inventory that needs to remain accurate while you're selling at a show

Shopify can keep those inventory quantities synchronized across the online store and physical/event sales. www.shopify.com

Big advantage: If someone at an event wants something you don't have with you, you can potentially turn that interaction into an online sale rather than losing it.

2. Square — seriously consider this

I'd choose Square if your business is event-heavy and you want the simplest possible setup.

Square has a very good small-business proposition: POS, payments, online store, inventory, customer information, etc. can all operate together. Its online store syncs orders, inventory, and customer data with the physical POS. squareup.com

It's particularly compelling if your typical scenario is:

Load merch into the van → go to event → set up table → sell from phones/tablets → come home → inventory is automatically updated.

A recent 2026 small-business POS comparison also ranked Square as its overall pick, particularly emphasizing its free POS option, built-in payments, inexpensive hardware, and suitability for selling on the go. fitsmallbusiness.com

The tradeoff: I'd give Shopify the edge if your ecommerce operation, marketing, online merchandising, and long-term digital sales are going to become a major part of the business.

3. Lightspeed

I'd put Lightspeed on the shortlist if you anticipate becoming a more sophisticated retail operation—lots of SKUs, purchasing, inventory complexity, multiple locations, etc.

For a small team primarily doing custom merch + events + ecommerce, though, I think it may be more system than you need initially.

What I'd do in your shoes

I'd run a head-to-head test of:

Shopify POS vs. Square

And I'd test them using your actual event workflow rather than comparing feature lists.

For example, take 20–30 of your real products and test:

1. Create products with size/color variants.
2. Load inventory.
3. Make 20 simulated event sales.
4. Do a return.
5. Sell something online.
6. Check whether inventory updates correctly.
7. Give another team member access to POS.
8. Test selling with a phone/tablet and unreliable event Wi-Fi.
9. See how quickly you can find a customer's previous order.
10. Look at the end-of-event sales/inventory report.

The biggest thing I'd pay attention to is inventory. For merch businesses, the nightmare isn't really taking the payment—it's discovering that you sold the last 2 XL black hoodies at an event, but the website still thinks you have 2 available.

Shopify is particularly strong here: its POS supports real-time inventory across locations and sales channels, including temporary/event inventory, and can handle transfers and purchase orders as you grow. www.shopify.com

My recommendation

If online is 40%+ of your business or you want it to become that: Shopify.

If events are the core business and online is primarily a complementary storefront: Square.

If you're already dealing with substantial inventory/retail complexity: investigate Lightspeed too.

If you tell me roughly (1) how many SKUs you carry, (2) how many events/month, (3) current online sales volume, (4) whether you need Shopify/WooCommerce/etc. compatibility, and (5) how many people will operate the POS, I can narrow this down to the best 1–2 choices and compare the actual monthly cost + card fees + hardware for your setup.

For a small merch team selling at live events + online, I’d narrow the field to Shopify, Square, and Lightspeed—with Shopify probably the best fit if ecommerce is an important part of the business.

My shortlist

1. Shopify — my first choice

For your particular model, Shopify's big advantage is that the online store and POS are actually the same inventory/order system. Shopify specifically supports selling through POS at markets and pop-ups, with orders and inventory synced between events and your online store. help.shopify.comwww.shopify.com

That matters a lot for merch. For example:

You take 30 black L hoodies to Saturday's event → sell 18 → Shopify automatically knows you have 12 left online.

You can also have multiple event sellers using the system, customer profiles, discounts, barcode scanning, shipping, online fulfillment, etc.

Current U.S. pricing starts around $39/month for Basic, with basic in-person selling included; POS Pro is an additional $89/location/month if you need the more advanced retail functionality. help.shopify.comwww.shopify.com

I'd choose Shopify if:

• Your online store is important or expected to grow
• You have lots of SKUs/sizes/colors
• You want one inventory database
• You do frequent events/pop-ups
• You may eventually sell through Instagram, marketplaces, wholesale, etc.
• You want a large ecosystem of merch, fulfillment, email, accounting, and marketing integrations

2. Square — seriously worth considering

Square is the one I'd demo alongside Shopify.

It's particularly attractive if your business is event-heavy and you want something that your team can pick up quickly. Square's POS has a free tier, and its online store can also be started with no monthly fee. squareup.com

Square also syncs online orders, in-person sales and inventory, and supports mobile payments, barcode scanning, exchanges, shipping, pickup, etc. squareup.com

I'd choose Square if:

• Live events are the primary sales channel
• Your ecommerce operation is relatively straightforward
• Keeping monthly costs low matters
• You want the simplest possible POS
• You don't need Shopify's enormous ecommerce ecosystem

The tradeoff is that Shopify is generally the stronger ecommerce platform, particularly as the online side gets sophisticated. Even Square's own comparison material positions Shopify as stronger for unified omnichannel/ecommerce capabilities. help.shopify.comwww.shopify.com

3. Lightspeed

I'd put Lightspeed third for you.

It's excellent when the hard problem is complex retail inventory—lots of products, locations, purchase orders, vendors, detailed reporting, etc. help.shopify.comwww.shopify.com

But if you're a small team doing merch at concerts, festivals, conventions, sporting events, etc., I suspect you'll appreciate Shopify/Square's simplicity more.

What I'd actually do

I'd run a Shopify vs. Square trial using a real event scenario, rather than comparing feature checkboxes.

Test these six things:

1. Create a 100-SKU merch catalog with sizes/colors.
2. Take the POS to an event using only a phone/tablet + card reader.
3. Process a bunch of rapid-fire sales while the line is moving.
4. See what happens when internet connectivity is poor.
5. At the end of the event, reconcile cash/card sales and inventory.
6. Place an online order afterward and make sure the inventory reflects the event sales correctly.

For a merch operation, #3–5 are more important than how pretty the ecommerce website is.

My recommendation

Start with Shopify unless your business is predominantly live-event sales.

I'd go:

Shopify → best long-term platform
Square → best simple/lean alternative
Lightspeed → only if your inventory/retail operations are unusually complex

One other thing I'd investigate is how you manufacture/fulfill the custom merch. If you're using a printer/fulfillment company for some products, that can change the recommendation considerably because Shopify has a very broad ecosystem of integrations.

If you tell me roughly (a) number of SKUs, (b) number of people selling at events, (c) number of events/month, (d) whether you make the merch yourselves or outsource it, and (e) approximate annual sales, I can narrow this down to a specific platform + POS hardware setup and estimated monthly cost.

For a small team selling custom merch both at live events and online, I’d put Shopify + Shopify POS at the top of the shortlist.

The key is that you want one product catalog, inventory, customer database, orders, and reporting system rather than a POS that merely connects to your ecommerce site.

My shortlist

1. Shopify POS — my first choice

Shopify is particularly well suited to your model because its POS and ecommerce operation share the same back office. Inventory can be synchronized across your online store, events/pop-ups, warehouses and other locations. Shopify also specifically supports mobile selling at pop-ups and events. www.shopify.com

For example, you could have:

• 100 black hoodies in inventory
• Sell 20 at a concert → inventory immediately becomes 80
• Sell 5 online → becomes 75
• Move 30 to your next event → transfer inventory
• Customer at the event wants a different size → look it up/order it
• Customer wants something you don't have at the event → sell it through the online catalog and ship it
• Customer later buys online → their customer/order history remains connected

That last couple of capabilities are particularly useful for merch: Shopify supports things like buy in person/ship to customer, buy online/return in person, pickup, and selling from wherever you have inventory. www.shopify.com

The other big advantage is the ecosystem. If your "custom merch" involves personalization, print-on-demand, embroidery, custom artwork, subscriptions, email marketing, etc., Shopify's app ecosystem gives you considerably more room to build around the core store.

2. Square Retail — definitely worth comparing

I'd look seriously at Square if your operation is event-heavy and relatively straightforward.

Square has a strong retail POS, inventory management, customer profiles, and online selling, with sales and inventory synchronized across channels. squareup.com

It's attractive if your priority is:

"We need to show up at an event with a couple of phones/readers, sell stuff, and have the inventory automatically update."

Square also now offers several ecommerce paths, including its own online store and integrations with platforms such as Shopify and WooCommerce. squareup.com

So there's a potentially interesting architecture of Square POS + Shopify ecommerce, although I'd generally prefer Shopify POS + Shopify ecommerce if ecommerce is going to be a major part of the business—you avoid introducing another synchronization layer.

3. Lightspeed

I'd put Lightspeed on the list if you're anticipating a larger inventory operation: lots of SKUs, multiple locations, purchasing, vendors, more complex retail processes, etc.

But for a small team doing merch at events, I'd want to see a compelling reason to accept the additional complexity rather than starting with Shopify.

What I'd choose for your particular business

I'd probably rank them:

1. Shopify + Shopify POS
2. Square + Square Online
3. Shopify + POS + custom-merch/personalization apps
4. Lightspeed

The important caveat is how you actually produce the custom merch.

If you're doing something like:

Customer chooses a shirt → chooses color/size → uploads artwork/name → you produce it → ship it

that's a different platform requirement from:

You manufacture 50 designs in advance → take boxes of them to concerts/festivals → sell them online and at events.

If you tell me (1) roughly how many SKUs/products you have, (2) whether the customization happens before or after the customer orders, (3) what you use to manufacture/fulfill the merch, and (4) roughly how many live events you do per month, I can narrow this down to the 2–3 systems I'd actually demo, including approximate costs and the event-day workflow.

For a small team selling custom merch both at live events and online, I’d narrow the field to Shopify, Square, and Lightspeed—with Shopify as my default recommendation.

My ranking

1. Shopify + Shopify POS — my first choice

For your model, Shopify has a particularly nice advantage: the event POS and online store are the same commerce system. Inventory, orders, customers and products can be managed from one back office, and Shopify explicitly supports mobile selling at pop-ups and events. www.shopify.comwww.shopify.com

That's valuable for merch because you might start an event with:

• 30 black L shirts
• 20 black M
• 15 hats
• 10 hoodies

…and sell 12 shirts at the event while someone simultaneously orders 3 online. The inventory should simply decrement rather than having you reconcile two systems later. Shopify says inventory is synced across POS, online and other sales channels in real time. www.shopify.com

It also handles product variants well—size, color, etc.—which is important for apparel. www.shopify.com

Current pricing: Shopify's Basic plan starts at $39/month monthly ($29/month billed annually), with in-person event selling included. The more advanced POS Pro functionality is an additional $89/month per location, but I'd probably start without POS Pro for a small event team. www.shopify.comwww.shopify.com

Shopify POS

2. Square — best if events are the center of the business

I'd look seriously at Square if you're saying:

"We're primarily an event/pop-up merch operation and our website is secondary."

Square is very good at the physical transaction side, and its ecommerce tools keep online sales, in-person sales, inventory and customer information together. squareup.com

The tradeoff is that I think Shopify gives you a stronger long-term ecommerce/merchandising platform if the online side becomes a significant part of the business.

Square

3. Lightspeed — worth considering if inventory gets complicated

Lightspeed becomes interesting if you expect a fairly large SKU catalog, multiple event locations, sophisticated purchasing, margins, pricing rules, etc.

It has strong inventory functionality and supports temporary pop-up locations, including transferring inventory into and out of those locations. retail-support.lightspeedhq.com

But for a small custom-merch operation, I'd be concerned about paying for capabilities you don't need yet. Current Retail pricing starts around $89/month and goes up from there. www.lightspeedhq.com

Lightspeed Retail

What I'd actually do in your shoes

Start with Shopify Basic + Shopify POS hardware.

Then structure the business around:

Shopify
→ master product catalog
→ online store
→ inventory
→ customer database
→ orders

Shopify POS
→ events
→ pop-ups
→ mobile checkout
→ card/tap payments
→ event-specific inventory

That gives you one source of truth rather than an online system + separate event POS + spreadsheets.

One particularly useful feature for merch is that Shopify supports things like buy in person/ship to customer, QR codes that let someone browse or buy online, and online/in-store order history. www.shopify.com

One important caveat

If by "custom merch" you mean you're taking custom orders at events—e.g. "put this name/logo on a hoodie, choose garment + color + size, we'll produce and ship it later"—I'd evaluate the platforms somewhat differently.

In that case, the important question isn't just POS + ecommerce. It's POS + product customization + quoting/order capture + production workflow.

If that's your model, tell me roughly what you're selling, how many SKUs/variants you have, and what happens when someone orders custom merch at an event, and I can give you a much more specific 2–3 platform recommendation.

For a small team selling custom merch at live events + online, I’d focus less on a traditional POS and more on a unified commerce platform that keeps inventory, customers, orders, and reporting together. Your biggest pain points will likely be:

• preventing overselling when the same hoodie sells at a show and online
• fast checkout with a small crew
• handling pop-ups/festivals/tours
• capturing customer emails/SMS at events
• managing variants (sizes, colors, designs)
• easy reorders and fulfillment

My shortlist:

www.shopify.com

My likely recommendation by scenario

1. You’re building a brand (artists, creators, bands, lifestyle merch):
→ Shopify + Shopify POS

This is usually the strongest long-term choice. You can run your website, event sales, email marketing, customer data, and inventory from one ecosystem. Shopify POS is designed to connect in-person sales with online inventory and customer data. www.shopify.com

Typical setup:

• Shopify online store
• Shopify POS Go or iPad POS for events
• barcode labels on merch
• Shopify Payments
• email/SMS capture at checkout
• shipping integration

2. You mainly sell at shows, markets, festivals, and occasional online:
→ Square

Square is excellent when the priority is “arrive, plug in, sell.” It has affordable hardware, mobile checkout, and an integrated online store option. squareup.com

Typical setup:

• Square Reader or Terminal
• Square Online store
• inventory by SKU
• simple customer database
• QR code signage for online orders

3. You have hundreds/thousands of SKUs or multiple sales teams:
→ Lightspeed

Worth considering if you’re managing:

• many designs
• multiple warehouses
• tour inventory
• wholesale accounts
• detailed purchasing/reordering

www.lightspeedhq.com

For a small merch operation, I’d probably avoid:

• WooCommerce + separate POS plugins unless you already have technical resources
• separate ecommerce and POS systems (Shopify website + unrelated POS) because inventory reconciliation becomes painful
• enterprise retail systems that require too much setup

A practical starter stack

For most small custom merch teams:

Shopify Basic + Shopify POS + barcode scanner + label printer + iPad
or
Square POS + Square Online if events are 80%+ of your sales.

A few questions would change the recommendation:

1. Are you selling your own branded merch (artist/creator/company) or making custom merch for clients?
2. Roughly how many SKUs do you carry (10, 100, 1,000+)?
3. Are live events occasional pop-ups, or are you touring every week?
4. Do you need print-on-demand integration, or do you hold inventory?
