For a small boutique with seasonal inventory and only occasional selling, I’d pick Big Cartel first.

Best fits

Big Cartel's free Gold plan allows 5 product listings, online payments, a mobile-friendly storefront, and no Big Cartel transaction fee; its Platinum plan is $15/month for up to 50 products. www.bigcartel.com

That makes it particularly well suited to a boutique that might have, say, 20–40 seasonal pieces, then go quiet between seasons. You aren't paying a substantial subscription during months when you're barely selling.

Square Online is the stronger choice if you already sell at pop-ups, markets, or a physical shop using Square. Its Free plan has no monthly subscription, and you pay processing fees when transactions occur. squareup.com

Square Online pricing

My recommendation

• Mostly online + small seasonal catalog: Big Cartel
• Online + craft fairs/pop-ups/physical checkout: Square Online
• You expect to turn it into a serious year-round ecommerce business: Shopify

For your particular description, I'd start with Big Cartel rather than paying Shopify every month for features you won't use.

For a small boutique with seasonal inventory that only sells occasionally, the best choice depends on how you define "low cost":

My recommendation

For an occasional seasonal boutique, I'd generally rank them:

1. Square Online — Best overall if you want the lowest ongoing cost and don't need advanced features.
2. Big Cartel — Excellent if your inventory stays small and you want a clean, boutique-style storefront.
3. Ecwid — Best if you already have an existing website or blog.
4. Shopify — Worth paying for only if you expect significant growth or need more sophisticated ecommerce features.

What matters most for seasonal sellers

Look beyond the monthly subscription and compare:

• Whether you can keep your store online during the off-season without paying much.
• Product limits (some inexpensive plans cap how many items you can list).
• Payment processing fees.
• Inventory management for adding and removing seasonal collections.
• Ease of restarting each season without rebuilding your catalog. www.shopify.comfitsmallbusiness.comfindhomegrown.com

If you can share approximately:

• How many products you typically sell (10, 50, 200?),
• Whether you sell only online or also at pop-up markets/events, and
• Your approximate monthly sales during peak season,

I can narrow it down to the best platform for your specific boutique.

For a small boutique with seasonal/occasional inventory, I’d lean toward Big Cartel—especially if you only have a few dozen products and don’t need a sophisticated ecommerce operation.

Best fits

Big Cartel is my pick. Its free Gold plan supports up to 5 products, online payments, variants such as sizes/colors, and basic reporting. Its $15/month Platinum plan expands that to 50 products and adds inventory tracking, discounts, shipping labels, and more customization. Big Cartel Big Cartel

That makes it particularly well suited to a boutique that might, for example, launch a spring collection of 15–30 items, sell through it, then essentially go dormant until fall. You aren't paying Shopify-level monthly costs during slow periods.

Choose Square Online instead if you already use Square for pop-ups, markets, or a physical shop. Its Free plan has no monthly fee and supports shipping, pickup, local delivery, and syncing with Square POS. Online card processing is currently 3.3% + 30¢ on the Free plan. Square Square

Choose Shopify if you expect the boutique to become a substantial online business—lots of SKUs, frequent promotions, abandoned-cart recovery, extensive integrations, etc. It's more powerful, but that power is probably unnecessary for an occasional seasonal seller. Shopify

Bottom line:

• Very small seasonal catalog: Big Cartel
• Seasonal + in-person/pop-up sales: Square Online
• Planning to scale seriously: Shopify

If you tell me roughly how many products/SKUs you carry during a season and whether you sell at physical markets, I can narrow it down to the cheapest option for your exact situation.

Bottom line:

Why Square fits your situation

If you might sell heavily for, say, fall and holiday seasons but have little or no activity the rest of the year, Square's $0/month Free plan is particularly attractive. It includes an online store, and Square says there are no monthly subscription costs—you pay processing fees when you take payments. squareup.com

For U.S. online payments, Square currently lists 3.3% + $0.30 per transaction on its Free plan. squareup.comsquareup.com

It also makes sense if you sell in person at pop-ups, markets, trunk shows, or seasonal events, because the same Square ecosystem can handle online and in-person sales.

My ranking for you:

1. 🥇 Square Online — best for low overhead and seasonal selling
2. 🥈 Ecwid — best if you already have a website you love
3. 🥉 Shopify — best if the boutique is likely to become a year-round business

If you tell me roughly how many products/SKUs you carry and whether you sell in person as well as online, I can narrow this down to the cheapest setup for your boutique.

For a small boutique with seasonal inventory and only occasional selling, I’d pick Big Cartel.

• Best overall: Big Cartel — Its free Gold plan supports up to 5 products, with no monthly fee, making it unusually well suited to seasonal/limited collections. If you need more inventory, Platinum is $15/month and supports up to 50 products. www.bigcartel.com
• Best if you also sell in person: Square Online — Square Free has $0/month software cost and combines online selling with Square's in-person payments/POS. You pay processing fees when you make sales. squareup.com
• Best if you expect to grow substantially: Shopify — More powerful, but probably more platform than an occasional seasonal seller needs. Shopify's Starter plan is $5/month but is geared toward simple/social selling rather than a full boutique storefront. www.shopify.com

My recommendation: Start with Big Cartel Gold if 5 products is enough for each seasonal drop. If your collections regularly exceed 5 items, Big Cartel Platinum at $15/month is still a very inexpensive way to have a proper storefront without committing to a larger ecommerce system. www.bigcartel.com

If you tell me roughly how many products you carry per season and whether you sell at pop-ups/in person, I can narrow it down to the cheapest option for your exact setup.

For a small boutique with seasonal inventory and occasional selling, I’d usually avoid paying for a full ecommerce subscription year-round. The best fit depends on whether you already have customers or need the platform to bring shoppers to you.

Best low-cost options

My recommendation for your situation

• Seasonal boutique + occasional sales + local customers: Square Online is probably the strongest choice. You can open the store only when inventory arrives, run seasonal drops, and keep inventory tied to in-person sales. squareup.com
• Small handmade/curated inventory and you need discovery from shoppers: Etsy is often cheaper because there’s little or no monthly commitment, though fees per sale are higher. zapier.com
• You already have a loyal customer base from Instagram/Facebook: Square Online or Shopify Starter may be enough.

I’d skip a full Shopify subscription unless you expect steady monthly sales, because the recurring fee can be hard to justify during your off-season. fitsmallbusiness.com

A good seasonal setup is often:

1. Keep a simple landing page year-round.
2. Activate your store before each collection launch.
3. Use email/SMS or social media to drive repeat buyers.
4. Archive sold-out seasonal items instead of maintaining a huge catalog.

If you tell me roughly how many items you carry (10 vs 500), whether you sell at markets/in person, and your average order price, I can narrow it down.

For a small boutique with seasonal inventory and occasional sales, I’d usually avoid a full-featured ecommerce subscription unless you expect steady growth. The best low-cost choices are:

My pick by situation:

• You sell a few collections a year + do craft fairs/pop-ups: → Square Online
  • You can keep the store dormant between seasons and avoid a monthly bill. squareup.com
• Your products are handmade, vintage, or discovery-driven: → Etsy
  • Good if you want built-in shopper traffic instead of bringing everyone yourself. help.etsy.com
• You want a branded boutique website but only a small catalog: → Big Cartel
• You expect weekly orders within a year: → Shopify becomes more attractive. www.shopify.com

For a seasonal boutique, I’d probably start with Square Online + Instagram/TikTok + email list, then move to Shopify only when the sales volume justifies the monthly cost.

A couple questions would change the recommendation:

1. Are your items handmade/vintage, clothing/accessories, or something else?
2. Do you already sell at markets/pop-ups/in a physical shop, or only online?

For a small boutique with seasonal inventory and only occasional selling, I’d prioritize low/no monthly cost, easy inventory changes, and the ability to pause between seasons.

My picks

Big Cartel is probably the sweet spot. Its free Gold plan supports up to 5 physical products with no Big Cartel transaction fee; the $15/month Platinum plan raises that to 50 products and adds inventory tracking, discounts, shipping labels, and more. www.bigcartel.com

Square Online is particularly attractive if your boutique occasionally sells at markets or pop-ups. Its Free plan has no monthly fee, and your online store can sync with Square's POS. Online card payments on the current Free plan are 3.3% + 30¢ per transaction. squareup.com

Shopify Starter is only $5/month, but it's deliberately lightweight—more useful for selling through social media, messages, and links than for running a traditional boutique storefront. www.shopify.com

What I'd choose

• 5 or fewer products at a time: Big Cartel Gold
• 5–50 seasonal products: Big Cartel Platinum
• You sell both online and at occasional markets: Square Online
• You mostly sell through Instagram/Facebook and don't need a full store: Shopify Starter

For your particular description, I'd start with Big Cartel, especially if the inventory changes substantially each season and you don't want to pay $30–$40+ every month for a store that's mostly dormant. www.bigcartel.com

For a small boutique with seasonal inventory and only occasional selling, I’d lean toward Big Cartel if you have a small catalog, or Square Online if you need a larger/unlimited catalog.

My pick: Big Cartel if your seasonal drops are only a handful of products. Its Gold plan is genuinely free, supports up to five products with variants, and is designed around simple selling. Its paid plan is $15/month if you need up to 50 products. www.bigcartel.com Big Cartel

Choose Square Online instead if a seasonal collection might have 10–100+ SKUs. Its Free plan has no monthly subscription, and Square says you only pay processing fees when you take a payment; its online processing rate is currently 3.3% + 30¢ on the Free plan. squareup.com Square Online

For your use case, I wouldn't pay for Shopify or Squarespace year-round unless you need their additional marketing/design capabilities. The key advantage of a $0/month platform is that your store can sit there between seasonal launches without eating into your margins. www.shopify.com

Bottom line:

• ≤5 products per seasonal drop: Big Cartel
• More than 5 products: Square Online
• Expecting to become a substantial year-round operation: Shopify

For a small boutique with seasonal inventory and only occasional selling, I’d pick Big Cartel.

• Best overall: Big Cartel — Its Gold plan is $0/month and supports up to 5 products, with online selling, payment acceptance, variants, and basic stats. That makes it particularly good if you open the shop only during seasonal drops. www.bigcartel.com
• Best if you need more than 5 products: Big Cartel Platinum — $15/month, up to 50 products. You can upgrade when your seasonal collection gets larger. www.bigcartel.com
• Best if you also sell in person: Square Online — Square has a $0/month Free plan, and it integrates online selling with Square's in-person POS. That's attractive for pop-ups, markets, or a physical boutique. squareup.com
• Shopify Starter is only $5/month, but it's more oriented toward selling through social links/messages than running a full standalone boutique storefront. www.shopify.com

My rule of thumb:
If you're selling a few seasonal collections and want to minimize costs while the store is quiet → Big Cartel.
If you're doing pop-ups + online sales and want inventory/POS synchronization → Square.

For your specific model, Big Cartel Gold → Platinum only during bigger seasons is probably the lowest-cost approach.

For a small boutique with seasonal inventory and only occasional selling, I’d lean toward Big Cartel.

Why Big Cartel stands out

Its Gold plan costs $0/month and supports up to 5 products, including variants such as sizes and colors. There are no platform selling fees; you still pay normal payment-processing fees. www.bigcartel.com

If your seasonal collection is larger, Platinum is $15/month and allows up to 50 products, with features such as inventory tracking and discounts. www.bigcartel.com

That makes it particularly attractive if you might open the shop for a few months around a season and then stop selling, rather than paying a larger monthly subscription all year.

Square is the better alternative if you also sell at craft fairs, pop-ups, or a physical boutique. Its Free plan has no monthly subscription and combines online selling with Square's POS system; U.S. online card payments on Square Free are currently 3.3% + $0.30. squareup.com

Bottom line:

• Mostly online + small seasonal assortment → Big Cartel
• Online + lots of pop-ups/in-person sales → Square
• Expecting substantial year-round growth → Shopify

If you tell me roughly how many products/SKUs you carry and how many months per year you sell, I can calculate which one would actually cost you the least.

For a small boutique with seasonal inventory and only occasional selling, I’d lean toward Big Cartel.

Big Cartel's free Gold plan currently supports 5 products, online selling, card/PayPal payments, variants, and sales-tax automation. Its Platinum plan is $15/month for up to 50 products. www.bigcartel.com

My pick: Big Cartel

It's particularly well suited if you:

• open the shop for a few months around each season,
• have a relatively small, curated catalog,
• don't want a subscription sitting there year-round,
• want a proper storefront rather than just payment links.

Big Cartel also advertises 0% platform selling fees, so you're primarily paying the normal payment-processing cost rather than a separate marketplace commission. www.bigcartel.com

Choose Square instead if the boutique also does pop-ups, markets, or a physical shop and you want your online and in-person inventory/POS ecosystem together. Square's Free plan has no monthly subscription, although online payments currently cost 3.3% + 30¢. squareup.com

I wouldn't choose Shopify for this particular use case unless you expect the boutique to become a more substantial year-round operation. Its $5 Starter plan is inexpensive, but it's designed primarily around social/multichannel selling rather than a full-featured independent storefront. www.shopify.com

Bottom line: Big Cartel for occasional seasonal selling; Square if you also sell frequently in person; Shopify if you're planning to grow substantially.

For a small boutique with seasonal inventory and only occasional selling, I’d pick Big Cartel first.

Best fits

Big Cartel is particularly well suited to your situation: its free Gold plan allows 5 physical products, has no Big Cartel transaction fee, and includes a mobile-friendly storefront and basic sales reporting. Its $15/month Platinum plan raises the limit to 50 products and adds inventory tracking, discounts, shipping labels, and more. www.bigcartel.com

Shopify Starter costs $5/month and is designed primarily for selling through social media and messaging rather than maintaining a traditional full-featured online store. help.shopify.com

My recommendation:

• 5 or fewer seasonal products: Big Cartel Gold
• Up to ~50 products: Big Cartel Platinum at $15/month
• Lots of pop-up/in-person selling: Square Online
• Mostly Instagram/Facebook/text links: Shopify Starter

For a boutique that might be closed or nearly dormant for several months between seasons, Big Cartel has the strongest economics because you can keep the storefront at $0/month rather than paying for an ecommerce subscription while you're not selling. www.bigcartel.com

Best low-cost options

www.shopify.com

My pick by scenario

• You sell a few seasonal collections (holiday, spring, pop-up events):

→ Square Online Free is probably the best value. You can keep the store available without paying during slow months, and only pay transaction fees when something sells. squareup.com

• You mainly sell handmade/curated items and need shoppers to discover you:

→ Etsy can work well because it provides marketplace traffic, though fees can add up. fitsmallbusiness.com

• You want a beautiful branded boutique site but only have 10–50 products at a time:

→ Big Cartel is worth considering.

• You expect to become a full-time boutique:

→ Start simple, then move to Shopify when inventory, marketing, and sales volume justify the monthly cost. www.shopify.com

For most occasional boutique sellers, I’d start with Square Online + Instagram/Facebook selling, or Etsy if your products fit its audience. A monthly Shopify plan is often unnecessary until you have steady sales. squareup.com

A couple of details would change the recommendation:

1. Do you sell mostly clothing/accessories, handmade goods, vintage, or gifts?
2. Do you already sell at in-person events or a physical storefront?
