For a boutique selling made-to-order products with long production times, I’d lean toward Shopify + a dedicated pre-order/backorder app.

My ranking

1. Shopify — best overall

• Shopify has a large ecosystem specifically for pre-orders, backorders, and made-to-order workflows. Its App Store currently has 100+ apps categorized for made-to-order pre-orders. Shopify App Store Shopify App Store
• Apps can handle things like “Pre-Order” buttons, expected ship dates, deposits/partial payments, backorders, waitlists, and customer notifications.
• This is particularly attractive for a boutique because you can make the long lead time very visible at the product level rather than treating the order like a normal “in-stock” purchase.
• For example, Dibs supports deposits, partial payments and split payments, while Preorder, Back in Stock Duck supports both pre-orders and backorders. Shopify App Store
• apps.shopify.com
• WooCommerce — best if you want maximum control

• WooCommerce's official Pre-Orders extension lets you charge upfront or when the item becomes available, assign availability dates, and manage pre-orders separately from ordinary orders. WooCommerce WooCommerce
• WooCommerce also has native backorder functionality, which is useful if you have products that are normally available but occasionally need to be ordered from the maker/supplier. WooCommerce
• The tradeoff is that you're responsible for WordPress hosting, maintenance, plugins, and more of the technical stack.

What I'd choose for your specific business

If your model is something like:

Customer orders → you make the item → 4–8 week production period → ship

I'd choose Shopify and configure the products as made-to-order/pre-order rather than simply “allowing backorders.”

The important features I'd insist on are:

• Expected production/ship date displayed before checkout
• “Made to order — ships in approximately 6–8 weeks” messaging
• Ability to take payment upfront
• Optional deposit/partial payment if the products are expensive
• Pre-order-specific order status
• Automatic customer emails when production/shipping status changes
• Ability to stop accepting orders after you reach your production capacity
• Separate handling for genuinely out-of-stock/backordered products
• Good support for product variants (size, color, customization)

Bottom line: Shopify is probably the easiest and most polished choice for this business model. WooCommerce is stronger if your production workflow is unusually customized and you want to build the system around your own processes.

If you tell me what you sell, typical lead time (e.g. 4–12 weeks), whether you take full payment or deposits, and roughly how many orders/month, I can narrow this down to the 2–3 best platforms/apps for your exact workflow and compare their costs.

For a boutique selling made-to-order products with long production times, I’d lean strongly toward Shopify.

Why it fits especially well:

• Pre-orders are a mature workflow. Shopify supports taking full, partial, or no payment upfront, depending on the setup. Shopify Help Center
• Backorders/pre-orders can be clearly distinguished from in-stock products, with the product page and order admin showing the pre-order status. Shopify Help Center
• There’s a large ecosystem of dedicated apps. For example, Shopify's current App Store has apps specifically for pre-orders + backorders + deposits + waitlists, including Dibs, Early Bird, Downpay, and others. Shopify App Store
• It works nicely for a boutique model where something might say “Made to order — ships in 6–8 weeks” rather than pretending you have inventory sitting on a shelf.
• Shopify is hosted/managed, so you don't have to maintain the underlying ecommerce infrastructure. Shopify

My shortlist

Shopify would be my default choice. The important caveat is that Shopify's native pre-order functionality still requires a pre-order app, rather than being completely native. Shopify Help Center

For your particular business model, I'd look at Shopify + a pre-order/deposit app rather than simply treating everything as an inventory backorder. Apps such as Dibs are particularly interesting if you want to collect a deposit or partial payment, while apps such as Early Bird explicitly support pre-orders, backorders, deposits and alerts. Shopify App Store

One thing I'd pay very close attention to is how the platform handles orders that contain both made-to-order and ready-to-ship items, because that's where boutique workflows can get messy.

If you tell me roughly how your production works (e.g. 4–8 week lead time, customer pays 50% upfront, limited monthly production slots, custom sizing/options), I can recommend the best Shopify/WooCommerce setup for that exact workflow.

For a boutique selling made-to-order products with long production times, I’d lean strongly toward Shopify.

The important distinction is that you want more than basic “out of stock” handling—you want pre-orders, backorders, deposits, production lead times, and clear customer communication.

My ranking

\*Usually depends heavily on plugins/extensions.

Why I'd choose Shopify

Shopify has a particularly strong ecosystem for this use case. Its App Store currently has 100+ pre-order apps with made-to-order functionality, including apps specifically supporting backorders, deposits, partial payments, waitlists, and restock notifications. apps.shopify.comapps.shopify.com

For example, you can structure a product as:

Made to Order — Ships in 6–8 weeks
Order now to reserve your piece. Your item will enter production after checkout.

And have the system accept the order even though you have zero physical inventory.

For a boutique, I'd particularly look at:

• PreProduct — good if you want sophisticated pre-order workflows and deposits.
• Downpay — particularly interesting for custom/made-to-order products and deposits.
• Dibs — supports pre-orders, backorders, deposits, partial payments and split payments.
• Preorder Now / Timesact — more straightforward if you primarily need pre-order buttons and back-in-stock functionality. apps.shopify.com

The feature I'd prioritize

If your production times are genuinely long—say 4–12+ weeks—I'd prioritize deposit/partial-payment functionality and order management over a simple “pre-order” button.

Ideally your workflow is:

Customer orders → deposit/payment collected → order marked as made-to-order → production queue → customer receives production update → fulfillment → remaining payment collected (if applicable).

That's a better fit than treating everything as ordinary inventory.

When I'd choose something else

BigCommerce makes more sense if you have a large/complex catalog, lots of variants, B2B requirements, or more complicated inventory rules. It's a solid platform, but for a small boutique I'd generally prefer Shopify's ecosystem and ease of implementation. www.shopify.com

WooCommerce is worth considering if you're already heavily invested in WordPress or need unusual customization. Its flexibility is excellent, but you're taking on considerably more technical/maintenance responsibility.

Bottom line: For a boutique where “we make it after you order it” is central to the business model, Shopify + a good pre-order/deposit app would be my first choice.

If you tell me roughly what you're selling, typical production time (e.g. 6 weeks), whether you want full payment or deposits, and your approximate monthly order volume, I can narrow it down to the best 2–3 setups and their current costs.

For a boutique selling made-to-order products with long production times, I’d put Shopify at the top of the list.

My ranking

Why Shopify: It has a particularly strong ecosystem for this exact situation. Shopify explicitly supports pre-orders, including taking payment upfront, deposits, or payment later. www.shopify.com

More importantly, its App Store currently has 100+ pre-order apps with made-to-order functionality, including apps that handle backorders, deposits, waitlists, restock notifications, and scheduled pre-orders. apps.shopify.comapps.shopify.com

For example, you can structure a product as:

Made to order — ships in 6–8 weeks
Order now to reserve your piece. Your card is charged today.
[Pre-order]

And the system can keep accepting orders even when physical inventory is zero.

The important distinction

For your business, I'd actually look for "made-to-order + pre-order", rather than conventional "backorder."

A traditional backorder means:

"We're temporarily out of stock, but more are coming."

Made-to-order means:

"We don't keep this in inventory; your order starts the production process."

That's a much better customer experience for a boutique because you can communicate the production lead time directly on the product page and checkout.

Shopify setup I'd consider

Shopify + a dedicated pre-order app is probably the sweet spot.

There are currently apps specifically supporting combinations like:

• pre-orders
• backorders
• deposits/partial payments
• pay-later pre-orders
• customer waitlists
• back-in-stock notifications
• production/shipping dates

For example, Dibs supports deposits, partial payments and split payments, while Downpay is aimed at deposits and custom/pre-order sales. apps.shopify.comapps.shopify.com

If your products are $300–$2,000+ and take 4–12 weeks to produce, I'd especially consider a deposit model rather than charging 100% immediately. Shopify's pre-order ecosystem supports that approach. www.shopify.com

Bottom line:
Shopify is my recommendation for most boutiques. WooCommerce becomes more attractive if your production workflow is unusually customized and you have technical help. BigCommerce is worth considering if you're building a substantially larger/complex catalog.

If you tell me (1) typical product price, (2) production time, (3) whether you want full payment or a deposit, and (4) roughly how many products/SKUs, I can narrow this down to the best 2–3 platforms and the specific pre-order setup I'd use for each.

For a boutique selling made-to-order products with long production times, I’d lean strongly toward Shopify.

Shopify has a particularly strong ecosystem for pre-orders/backorders: its App Store currently has 100+ pre-order apps, including apps specifically supporting made-to-order, backorders, deposits, partial payments, ship dates, waitlists, and restock notifications. apps.shopify.com

My ranking

Why Shopify stands out: you can make the customer's experience very explicit—e.g. "Made to order — ships in 6–8 weeks", take payment or a deposit, accept orders even when inventory is zero, and manage those orders separately from ready-to-ship inventory. There are also apps that combine pre-orders with back-in-stock notifications and waitlists. apps.shopify.com

For example, Shopify's current ecosystem includes Dibs for deposits/partial or split payments, Downpay for custom/pre-order deposits, and Preorder Wolf for pre-orders/backorders. apps.shopify.com

One important distinction

If your products are always made after someone orders, I wouldn't actually structure the store primarily as "backorders."

I'd use a made-to-order workflow:

Available to order → Production time: 6–10 weeks → Order placed → Production → Customer notified → Ships

That's cleaner for customers than making a deliberately unstocked product look like it's "out of stock."

If you tell me roughly how long your production times are (e.g. 2–4 weeks vs. 3–6 months), whether you want full payment or deposits, and whether each item has customizable options, I can recommend the best Shopify vs. WooCommerce setup and the specific pre-order app I'd use.

For a boutique selling made-to-order products with long production times, I’d lean toward Shopify as the best overall platform.

My ranking

Why Shopify stands out: its ecosystem has a large selection of pre-order apps specifically supporting made-to-order, backorders, deposits, partial payments, waitlists, and estimated ship dates. apps.shopify.comapps.shopify.com

For example, Shopify's current app marketplace includes options such as Dibs, which supports deposits/partial payments, Downpay, designed for custom and pre-order sales, and Preorder Wolf, which handles pre-orders and backorders. apps.shopify.comapps.shopify.com

The important distinction for your business

If your products take, say, 6–12 weeks to produce, I wouldn't treat them simply as "out of stock."

You ideally want the customer to see:

Made to Order — Ships in approximately 8–10 weeks

and be able to:

• place the order even though you have zero inventory
• collect full payment or a deposit
• show an estimated production/shipping date
• prevent accidental overselling if you have production capacity limits
• send order/status updates
• distinguish pre-orders from ordinary in-stock orders
• handle cancellations/refunds cleanly
• optionally close orders once you reach your production capacity

Shopify is particularly good at building this workflow with an appropriate pre-order/custom-order app. Its marketplace currently has 100+ apps categorized around pre-orders, including ones explicitly supporting made-to-order products. apps.shopify.comapps.shopify.com

When I'd choose WooCommerce instead

I'd choose WooCommerce if your made-to-order process is unusually customized and you're comfortable managing WordPress.

Its official Pre-Orders extension supports an availability date, upfront payment or payment upon release, and can transition a product from pre-order to normal ordering. WooCommerce also distinguishes pre-orders from traditional backorders. woocommerce.com

That makes it powerful, but generally more hands-on than Shopify.

My recommendation

For a boutique, I'd probably build it as:

Shopify + a good pre-order/custom-order app + Shopify Payments

rather than trying to make the native inventory system do everything.

If you tell me (1) typical production time, (2) whether you want full payment or deposits, (3) whether customers can order unlimited quantities, and (4) roughly how many products/orders you expect, I can recommend the specific Shopify vs. WooCommerce setup and apps I'd use.

For a boutique where almost everything is made to order and production can take weeks, I’d shortlist Shopify and WooCommerce, with Shopify probably the easiest overall.

My ranking

1. Shopify — my first choice.
Shopify has a large ecosystem specifically for pre-orders, backorders and made-to-order selling. Its App Store currently has 100+ pre-order apps with made-to-order features, including apps supporting deposits, partial payments, backorders, ship dates and restock notifications. apps.shopify.com

This is particularly useful if your workflow is something like:

Customer orders → you start production → estimated production time is 4–8 weeks → customer gets updates → you ship when finished.

You can make the product page very explicit: “Made to order — ships in approximately 6 weeks”, rather than pretending the item is immediately available.

2. WooCommerce — potentially better if your workflow is complicated.
WooCommerce's official Pre-Orders extension is unusually capable: you can charge upfront or upon release, set availability dates, change release dates, email everyone who pre-ordered, and manage pre-orders separately from normal orders. woocommerce.com

It also distinguishes properly between pre-orders (product isn't available yet) and backorders (existing product temporarily unavailable). woocommerce.com

I'd choose WooCommerce if you need things like highly customized production workflows, bespoke product configurations, unusual payment arrangements, or integration with other WordPress systems.

3. Square — good for a simpler operation.
Square Online supports pre-orders with specific availability/fulfillment dates, although it's more oriented toward straightforward scheduled fulfillment than sophisticated long-production workflows. squareup.com

4. Squarespace — beautiful, but I'd avoid it for this particular requirement.
Squarespace can accommodate selling products before they're in stock, but it explicitly doesn't have a built-in mechanism for pre-ordering out-of-stock products; its recommended solution for sold-out items is a waitlist. support.squarespace.com

What I'd choose for your boutique

If you're not technically minded, I'd go:

Shopify + a good pre-order app

The important thing isn't simply having a “pre-order” button. I'd look for a system that gives you:

• Made-to-order status
• Estimated production/ship date displayed at checkout
• Ability to take full payment or a deposit
• Backorders when you exceed your normal production capacity
• Customer emails when production/fulfillment status changes
• Separate visibility of pre-orders in your admin
• Ability to cap the number of orders you can accept
• Variant-level handling (e.g. different sizes/colors have different lead times)
• Clear messaging that the item won't ship immediately
• Ability to combine or separate made-to-order and ready-to-ship products in the same order

That last point is particularly important for a boutique: you don't want a customer buying a ready-to-ship item and a 6-week made-to-order item and then wondering why their entire order hasn't arrived.

If you tell me roughly how your production works (e.g. “customer orders, I make it in 4–6 weeks, then ship” vs. “I collect orders for 2 weeks and manufacture them as a batch”), I can tell you which platform/workflow I'd use and which Shopify/WooCommerce setup fits it best.

For a boutique selling made-to-order products with long production times, I’d put Shopify at the top of the list.

My ranking

1. Shopify — best fit

Shopify is particularly good because its ecosystem has a large number of dedicated pre-order/made-to-order apps. The Shopify App Store currently lists 100+ pre-order apps with made-to-order functionality, including options for backorders, deposits, partial payments, waitlists, and production-related messaging. apps.shopify.com

Shopify's own pre-order functionality can support full, partial, or no payment at checkout, depending on the setup, and lets you manage the resulting orders through Shopify admin. help.shopify.com

For a boutique, I'd look especially at:

• Downpay — good if customers pay a deposit and the balance later.
• Dibs — specifically handles preorders/backorders and partial or split payments.
• PreProduct — strong for more sophisticated preorder workflows.
• Timesact / STOQ — good if you mainly need straightforward preorder + back-in-stock functionality.

The important distinction for your business is that you probably don't just want a "preorder" button. You want something like:

Made to order — ships in approximately 8–12 weeks

Customer places order → production queue → you make item → fulfill when finished.

Shopify's app ecosystem is unusually well suited to building that workflow. apps.shopify.com

2. WooCommerce — excellent if your workflow is more complicated

WooCommerce is probably my second choice, and potentially first if you have unusual production rules.

Its official Pre-Orders extension allows you to set availability dates, charge customers immediately or when the order becomes available, change release dates, and manage pre-orders separately from ordinary orders. It can also enable pre-orders when a product goes out of stock. woocommerce.com

WooCommerce also distinguishes between pre-orders and backorders, and its core backorder functionality can handle variation-level situations that the official Pre-Orders extension can't. woocommerce.com

That's attractive if, for example:

• each size/color has a different production time
• some products are made-to-order while others are stocked
• you need complicated fulfillment rules
• you want your own custom production-management logic

The tradeoff is that you're taking on more technical/admin overhead than with Shopify.

3. BigCommerce

I'd consider BigCommerce if you're expecting a larger operation—lots of SKUs, more sophisticated catalog management, B2B, multiple sales channels, etc.

For a small luxury/boutique brand whose main unusual requirement is "customers buy things that won't be ready for 8–16 weeks," though, I don't think I'd choose it over Shopify.

4. Squarespace — probably not

Squarespace is attractive for a design-led boutique, but its current pre-order functionality is much less compelling. Squarespace explicitly says there is no built-in way to accept pre-orders for products that are out of stock; its native solution is primarily product waitlists. It does provide guidance for manually selling products before they're in stock, but that's a less sophisticated workflow. support.squarespace.com

So I'd choose Squarespace for "beautiful website + relatively simple commerce," not for "production happens after every order."

What I'd choose for your specific business

Shopify + a good preorder/deposit app would be my recommendation.

In particular, if your products are expensive and take months to make, I'd seriously consider a deposit model rather than charging 100% immediately:

Order placed → 30–50% deposit → production → notification → remaining balance → shipment

That gives you cash flow for production while making the long lead time feel more natural to the customer.

If you tell me (1) typical production time, (2) average order value, (3) whether you want full payment or deposits, and (4) whether customers can mix made-to-order and ready-to-ship items in one cart, I can narrow this down to the best platform + specific app/workflow for your boutique.

For a boutique selling made-to-order products with long production times, I’d lean toward Shopify—especially if your main concern is making pre-orders/backorders feel polished to customers without building a lot of custom functionality.

My ranking

Why Shopify stands out: Shopify has a large ecosystem of dedicated pre-order apps, including apps specifically supporting made-to-order, backorders, deposits, partial payments, ship dates, and waitlists. Its App Store currently lists more than 100 pre-order apps. apps.shopify.com

For example, Dibs supports pre-orders/backorders with deposits and split payments, while Downpay is aimed at deposits and partial payments for custom and pre-order sales. apps.shopify.com

For your particular business

If a customer orders something that takes, say, 6–10 weeks to make, I'd set it up so the product page clearly says:

Made to Order — Ships in 8–10 Weeks

Then the platform should let you:

• accept the order even when there isn't inventory
• clearly identify the order as a pre-order/made-to-order
• communicate the expected production/shipping date
• take full payment or a deposit
• prevent accidental overselling if you have production capacity limits
• send customers updates while their item is being made
• handle cancellations/refunds cleanly
• distinguish made-to-order orders from normal in-stock orders

Shopify + a good pre-order/deposit app is probably the sweet spot. Shopify's own pre-order ecosystem explicitly supports made-to-order products, and several apps have substantial merchant adoption. apps.shopify.com

When I'd choose WooCommerce instead

I'd choose WooCommerce if your made-to-order process is unusually complicated—for example, lots of custom fields, complex pricing formulas, production workflows, or deep integration with an existing WordPress site. WooCommerce has an official Pre-Orders extension with availability dates, launch messaging, flexible charging, and the ability to open pre-orders when a compatible product goes out of stock. woocommerce.com

Bottom line:
Shopify if you want the easiest, polished boutique experience.
WooCommerce if your production/customization workflow needs extensive customization.

If you tell me roughly how your made-to-order process works (e.g. “customer pays 50% upfront, we make it in 6–8 weeks, then collect the balance”), I can narrow this down to the best platform + specific app combination.

For a boutique selling made-to-order products with long production times, I’d put Shopify first, with WooCommerce as the strongest alternative.

My ranking

1. Shopify — my pick

Shopify is particularly good if your model is:

Customer orders → you manufacture it → customer waits → you ship it.

Its pre-order system can collect full, partial, or no payment upfront, and you can manage pre-orders through the Shopify admin. Shopify itself requires a pre-order app rather than making the functionality entirely native. help.shopify.com

The big advantage is the ecosystem. There are currently numerous highly rated apps specifically handling pre-orders, backorders, deposits, waitlists, and back-in-stock notifications. apps.shopify.com

For a boutique, I'd particularly look at apps supporting deposits/partial payments if your production costs are substantial. Shopify's app ecosystem includes options specifically designed for custom and pre-order sales. apps.shopify.com

Why I'd choose it: You can make the customer experience very clear:

"Made to order — ships in 6–8 weeks"
→ Add to cart
→ Pay deposit or full amount
→ Order sits in production
→ Fulfill when finished
→ Automated customer communications.

2. WooCommerce — best if your workflow is unusual

WooCommerce is arguably more powerful for a genuinely custom production business.

Its official Pre-Orders extension supports paying upfront or upon release, setting availability dates, automatically charging customers when the item is ready, changing release dates, emailing everyone who pre-ordered, and managing pre-orders separately from normal orders. woocommerce.com

WooCommerce also has native backorder functionality, and its ecosystem can handle more elaborate production rules. woocommerce.com

I'd choose it if you need things like:

• Different lead times for different products/variants
• Complex customization
• Deposits and staged payments
• Custom production statuses
• Integrations with manufacturing/ERP systems
• Very unusual fulfillment logic

The tradeoff is that you'll have more setup and maintenance than with Shopify.

3. BigCommerce

BigCommerce is worth considering if you're expecting a relatively large catalog or more complicated commerce operation. It's generally positioned more toward larger/complex catalogs and multi-storefront businesses. technologyadvice.com

For a small or mid-sized artisan boutique, though, I wouldn't choose it specifically for its pre-order capabilities.

What I'd actually do for your business

If you're making things like furniture, jewelry, clothing, ceramics, leather goods, art objects, or other bespoke products, I'd probably build it as:

Shopify + a good pre-order/deposit app

rather than trying to force "backorder" functionality to do the job.

There's an important distinction:

• Pre-order: "This product isn't ready yet; order now and we'll make it for you."
• Backorder: "This normally-stocked product is temporarily unavailable; order now and we'll ship it when replenished."
• Made-to-order: "We don't keep inventory; your order starts the production process."

For your model, made-to-order + pre-order semantics are usually the cleanest customer experience.

If you tell me what you're selling, typical production time (e.g. 4–8 weeks), whether you want a deposit or full payment, and roughly how many products/variants you have, I can narrow this down to the best platform + specific app combination.

For a boutique selling made-to-order products with long production times, I’d put Shopify at the top of the list.

Best fit: Shopify

Shopify is particularly strong here because its ecosystem has mature support for pre-orders, backorders, deposits, made-to-order products, and customer notifications. Shopify’s current pre-order system can support full, partial, or no payment upfront, depending on the setup. help.shopify.com

The big advantage is the app ecosystem. There are currently 100+ Shopify pre-order apps with made-to-order functionality, including tools for:

• Taking pre-orders even when inventory is zero
• Showing estimated production/ship dates
• Taking deposits or partial payments
• Managing backorders
• Separating pre-order and regular products
• Sending "back in stock" / restock notifications
• Limiting how many units can be pre-ordered
• Handling different lead times by product or variant apps.shopify.com

For example, Dibs supports deposits, partial payments, and split payments, while Preorder, Back in Stock Duck specifically supports presales, backorders, and waitlists. apps.shopify.com

How I'd rank the main options

Shopify is also currently regarded as one of the strongest ecommerce platforms for scaling brands, while BigCommerce tends to be better suited to complex catalogs and multi-storefront setups. technologyadvice.com

One important distinction

For your business, I'd actually structure products as "made to order" rather than "out of stock/backordered" whenever possible.

For example:

Made to Order — Ships in 6–8 weeks

rather than:

Out of Stock — Pre-order

That communicates that the customer is intentionally commissioning an item, rather than waiting for inventory to come back.

My recommendation: Shopify + a dedicated pre-order/made-to-order app. If you tell me roughly how many products you have, whether customers pay 100% upfront or a deposit, and your typical production time (e.g. 4–6 weeks vs. 3–6 months), I can narrow it down to the best 2–3 Shopify setups for your boutique.

For a boutique selling made-to-order products with long production times, I’d lean strongly toward Shopify.

My ranking

Why Shopify is my first choice: its current pre-order system supports products that aren't ready for fulfillment, and you can use apps to handle full, partial, or delayed payment. Pre-orders are managed within the Shopify admin alongside normal orders. help.shopify.com

More importantly for your situation, Shopify has a large ecosystem specifically around made-to-order, pre-order, and backorder workflows. Its App Store currently lists 100+ pre-order apps with made-to-order functionality, including apps supporting deposits, partial payments, backorders, waitlists, and restock notifications. apps.shopify.com

The workflow I'd use

For a boutique where an item might take 4–12+ weeks to produce, I'd set it up something like:

Product page → "Made to Order — Ships in 6–8 Weeks" → customer orders → order is tagged/held as pre-order → production → fulfillment → customer receives shipping notification.

You can also offer:

• Full payment upfront — simplest operationally.
• Deposit + balance later — particularly attractive for expensive custom pieces.
• Pay later — useful if production times are uncertain.
• Backorder — when you temporarily exceed your available production capacity.
• Waitlist — when you've stopped accepting orders but want to capture demand.

Shopify explicitly supports different pre-order payment approaches, including full, partial, or no payment at the time of order, depending on the app/setup. help.shopify.com

One important distinction

If these are true made-to-order products—e.g. "Order today, we'll manufacture yours and ship in 8 weeks"—I'd actually design the store around made-to-order purchasing, rather than treating everything as a conventional "pre-order."

That's because customers need very clear expectations around the production window. Shopify's current guidance also requires merchants to have a reasonable basis for their promised shipping timeframe and to communicate revised dates if they can't meet it. help.shopify.com

BigCommerce is the runner-up. It's particularly interesting if you expect a larger catalog or more sophisticated inventory rules; its current storefront tooling explicitly supports backorderable products, including unlimited backorders and customer-facing backorder quantity messaging. docs.bigcommerce.com

Bottom line: for a boutique, I'd choose Shopify + a good pre-order/deposit app rather than choosing a platform solely on its native backorder functionality.

If you tell me roughly (1) average production time, (2) average order value, (3) whether you want a deposit or full payment, and (4) how much customization each order has, I can narrow it down to the best Shopify setup—or tell you if BigCommerce/WooCommerce would actually be better.

For a boutique selling made-to-order products with long production times, I’d lean strongly toward Shopify.

Why it fits especially well:

• Pre-orders and backorders are mature: Shopify has a large ecosystem of dedicated apps for pre-orders, backorders, waitlists, deposits, and “coming soon” products. apps.shopify.com
• Made-to-order is explicitly supported: The Shopify App Store currently has 100+ pre-order apps/features covering made-to-order workflows. apps.shopify.comapps.shopify.com
• You can communicate production times: You can make the product page say something like “Made to order — ships in 6–8 weeks” rather than treating the item as simply “out of stock.”
• Deposits/partial payments: Some apps support taking a deposit at checkout and collecting the balance later, which can be useful for higher-priced bespoke pieces. apps.shopify.comapps.shopify.com
• Customer notifications: Pre-order apps can handle restock/production notifications and waitlists, reducing the amount of manual emailing you have to do. apps.shopify.com
• Room to grow: Shopify is also currently regarded as one of the stronger platforms for scaling ecommerce businesses. technologyadvice.com

My ranking for your use case

The important distinction is that you don't necessarily want a conventional “backorder” system. For a made-to-order boutique, I'd build the experience around pre-orders + production lead time, so the customer knows before paying that their item is being produced specifically for them.

For example:

Made to order
This piece is crafted especially for you. Please allow 6–8 weeks for production before shipping.

Then the order automatically enters your production queue.

If you're choosing Shopify, I'd look specifically at the pre-order apps that support made-to-order and/or deposits rather than relying on Shopify's basic inventory behavior. The current Shopify App Store has several well-reviewed options, including Dibs, PreProduct, Timesact, and REZ. apps.shopify.comapps.shopify.com

If you tell me roughly how your boutique works (e.g. “customer orders → I make it in 4–8 weeks → ship,” whether you take full payment or deposits, and whether customers can customize items), I can recommend the best Shopify vs. WooCommerce setup and the specific pre-order app/workflow I'd use.

For a boutique selling made-to-order products with long production times, I’d put Shopify at the top of the list.

For your particular business model, I'd structure it like:

Product: “Made to order — ships in 6–8 weeks”
Button: “Pre-order” / “Order now”
Checkout: Customer pays in full or a deposit
Order: Automatically flagged as a pre-order
Customer: Gets confirmation with expected production/shipping window
You: See all outstanding orders and fulfill them as production batches are completed

There are also Shopify apps specifically geared toward deposits and partial payments for custom/pre-order sales, which can be useful if your items are expensive. apps.shopify.comapps.shopify.com

One important distinction

If you're always producing an item after someone orders it, I wouldn't necessarily call it a "backorder." I'd configure it as made-to-order with a clearly stated production lead time.

If you're collecting orders before you start a production run, that's more naturally a pre-order.

If you're selling something that is temporarily unavailable but will be replenished, that's a backorder.

Shopify can accommodate all three, which is why I'd favor it for a boutique.

If you tell me roughly how your production works (e.g. “customer orders → I make it in 6 weeks” vs. “I open orders for 2 weeks → manufacture a batch”), I can recommend the best Shopify setup/apps and the cheapest way to implement it.
