Neutral mentions of BigCommerce

For an agency building lots of client sites under your own brand, I’d put Duda at the top of the shortlist.

My recommendation

1. Duda — my default choice

Duda is specifically designed around the agency → client relationship rather than individual businesses building their own sites.

Its white-label functionality can cover the client login, editor, dashboard, previews, emails, branding, and domain, so your clients can interact with your agency's branded platform rather than obviously seeing Duda. Duda Duda

It also has built-in ecommerce, APIs, reusable templates, permissions, hosting, SSL, and client-management functionality. Duda Duda

The particularly interesting part for an agency is the ability to create reusable components/templates and manage many sites centrally. Duda also supports API-based automation on its higher-level plans. Duda Duda

I'd choose Duda if: your business model is "we build and manage websites for SMBs" and you want to productize that service.

2. Wix Studio — strong alternative

Wix Studio is particularly compelling if design flexibility and ecommerce capabilities matter more than having the deepest possible white-label experience.

It has multi-site management, team collaboration, reusable assets, client permissions, custom code/API capabilities, and native ecommerce. Its ecommerce stack supports things like customizable checkout, inventory, multiple currencies, international shipping, 80+ payment providers, marketplaces, and POS. wix.com wix.com

Wix also offers agency custom branding for client-facing experiences. Wix Support

wix.com

I'd choose Wix Studio if: you're selling more premium/custom-designed sites and ecommerce is a substantial part of your business.

3. BigCommerce — when ecommerce is the product

If you're building stores where ecommerce complexity is the primary concern—large catalogs, B2B, multiple storefronts, sophisticated integrations, etc.—I'd look at BigCommerce rather than forcing an SMB-oriented site builder to do everything.

BigCommerce explicitly has an agency partner program and supports customizable checkout, multi-storefront, B2B functionality, headless implementations, APIs and integrations. BigCommerce BigCommerce

bigcommerce.com

The tradeoff is that it's not really the same kind of turnkey white-label website-builder experience as Duda.

What I'd do for your agency

If you're trying to standardize your stack, I'd seriously consider:

Duda → default platform for 70–90% of clients
BigCommerce → larger/complex ecommerce clients
Custom development → exceptional projects that don't fit either

That gives you a repeatable production system instead of having every client become a bespoke development project.

One important question changes my recommendation substantially: are you looking for a platform where clients can log in and edit their own sites under your agency's brand, or do you mainly want an agency platform where your team builds/manages the sites?

If analytics + conversion optimization are core requirements, I’d narrow it to Shopify, Wix, and BigCommerce rather than general-purpose site builders.

How I’d compare them

Shopify is particularly compelling if conversion is the priority: its checkout is built specifically around ecommerce, and its ecosystem has thousands of apps for experimentation, personalization, reviews, upsells, email/SMS, and other CRO functions. Shopify also added additional analytics/insight capabilities in 2026. Shopify Shopify

Wix has unusually good analytics directly inside the builder. Its ecommerce analytics includes conversion funnels, abandoned-cart funnels, product conversion, AOV, returning customers, traffic sources, custom reports, and Google Analytics integration. Wix Help Center Wix Help Center wix.com

BigCommerce is worth considering if you care more about deep ecommerce reporting than visual simplicity. Its built-in reporting covers storefront conversion rates, AOV, cart abandonment, customer/product trends, sales channels, and detailed exports. BigCommerce BigCommerce

Webflow is the outlier: excellent if the site experience and landing pages are the differentiator. Its native analytics now includes traffic, conversions, clickmaps, and scrollmaps, while ecommerce tracking can connect to Google Analytics and other optimization tools. Webflow Webflow Help Center

My practical shortlist

• You want a serious ecommerce growth machine: Shopify
• You want analytics baked deeply into an easy website builder: Wix
• You have complex catalogs/operations and want extensive ecommerce reporting: BigCommerce
• You’re a design-first brand where the website experience matters most: Webflow

If you tell me your approximate monthly revenue, number of products, and whether you sell physical products, digital products, or subscriptions, I can compare the 2–3 most relevant options specifically around analytics, A/B testing, funnels, abandoned carts, upsells, personalization, and checkout conversion.

My practical shortlist

If your priority is analytics + conversion optimization built into the ecommerce experience, I’d narrow the field to a few platforms rather than general website builders.

My shortlist

Shopify Shopify## My recommendation by scenario

Pick Shopify if:

• Your website’s main purpose is selling products
• You care about improving:

• conversion rate
• checkout completion
• abandoned carts
• customer lifetime value
• email/SMS remarketing
• upsells and bundles
• You expect your catalog or revenue to grow

Shopify has a large ecosystem of ecommerce-focused apps and built-in selling tools, including analytics and checkout features designed around commerce. Shopify Shopify

Pick BigCommerce if:

• You have:

• many SKUs
• complex product options
• wholesale/B2B needs
• multiple storefronts or regions

It tends to fit businesses where the store operations are more complicated than the website itself. Shopify

Pick Wix if:

• You’re a service business, creator, local brand, or small shop
• The website experience matters as much as the store
• You want easier visual editing

Wix combines drag-and-drop building with ecommerce, marketing, and analytics tools, making it approachable for smaller teams. Tech.co

Pick Squarespace if:

• Brand presentation is a major driver of sales
• You sell:

• premium products
• creative goods
• memberships
• editorial/lifestyle products

It offers strong design and commerce reporting, though it generally has fewer advanced ecommerce extensions than Shopify. Forbes

Features I’d insist on before choosing

Regardless of platform, look for:

• Funnel reporting (product view → cart → checkout → purchase)
• Cohort/customer reporting
• A/B testing support or integrations
• Email/SMS automation
• Abandoned cart recovery
• Upsells/cross-sells
• Customer segmentation
• Google Analytics 4 + ad pixel support
• Fast checkout on mobile
• Product search analytics

Bottom line

For a serious ecommerce operation, I’d start with Shopify.
For a beautiful brand site that also sells, look at Wix or Squarespace.
For complex inventory and scaling operations, consider BigCommerce.

If you tell me your business type (physical products vs digital, monthly sales volume, number of products, and whether you run ads), I can narrow it to one choice.

For a boutique where everything is made to order and production can take weeks or months, I’d look primarily at Shopify + a strong preorder/backorder app rather than relying on a platform’s basic “out of stock” functionality.

How the main options compare

Shopify stands out for your particular model. Its App Store currently has a large selection specifically tagged for made-to-order products, including apps handling preorders, backorders, waitlists, ship dates, and deposits. Shopify App Store Shopify App Store

A few relevant Shopify approaches:

• Preorder + backorder app: Lets a product continue accepting orders after inventory hits zero, while displaying that it's a preorder/backorder.
• Deposit/partial-payment setup: Particularly useful if your items are expensive and customers shouldn't have to pay the full amount months before delivery. Apps such as Dibs and Downpay specifically support deposits or partial payments. Shopify App Store
• Production/ship-date messaging: Important for your business because “ships in 8–12 weeks” needs to be prominent at the product and checkout stages.
• Waitlist/restock notifications: Useful when you temporarily stop accepting orders or have limited production capacity.

WooCommerce is worth considering

WooCommerce's official Pre-Orders extension supports availability dates, launch messaging, and different charging approaches. WooCommerce also distinguishes pre-release preorders from ordinary backorders, and can allow preorders when a product goes out of stock. WooCommerce

The tradeoff is that WooCommerce gives you considerably more control, but you'll generally have more technical configuration and maintenance than Shopify.

For a made-to-order boutique, I'd prioritize these features

1. Unlimited/controlled backorders — don't let inventory reaching zero automatically stop sales.
2. A visible production window — e.g. “Made to order — ships in 10–12 weeks.”
3. Automatic customer communication — order confirmation, production updates, delay notices, shipping notification.
4. Deposits or delayed payment — particularly if your products are high-ticket.
5. Order tagging by production batch — so you can see which customers belong to each production run.
6. Ability to cap orders — crucial if you can only produce 30 pieces per month.
7. Easy handling of delays — changing an estimated ship date without manually contacting every customer.
8. Separate preorder inventory from ready-to-ship inventory if you eventually sell both.

If you tell me roughly what you're selling (fashion, furniture, jewelry, art, etc.), your typical production time, and whether customers pay 100% upfront or a deposit, I can narrow this down to 2–3 specific platforms/setups that fit the workflow.

For a boutique selling made-to-order products with long production times, I’d focus less on generic “backorder” support and more on preorders, deposits/partial payments, promised ship dates, and clear order-status communication.

How the main options compare

Shopify is probably the most straightforward choice for a boutique. Shopify supports preorders, including full or partial payment options, and has a large ecosystem of preorder apps specifically supporting made-to-order products. Shopify Help Center Shopify App Store

For example, its app marketplace currently has apps supporting combinations of preorders, backorders, deposits, waitlists, and restock notifications. Shopify App Store Shopify App Store

One important caveat: Shopify's native preorder functionality requires a preorder app, and there are restrictions around accelerated checkout/payment methods. Shopify also expects merchants to have a reasonable basis for their promised shipping timeframe. Shopify Help Center

BigCommerce is particularly interesting if your definition of “backorder” is literally sell it now even though inventory isn't available. Its September 2026 update added shopper-facing backorder messaging across product pages, cart, checkout, and order confirmation, including quantity and shipping-expectation messaging. BigCommerce

WooCommerce gives you the most flexibility if your workflow is unusual. Its official Pre-Orders extension supports availability dates, launch messaging, flexible charging, and preorders for products that go out of stock. WooCommerce

For your particular business

If, for example, your workflow is:

Customer orders → you collect a deposit → item takes 6–10 weeks to manufacture → you notify customer → collect balance → ship

I'd lean toward Shopify + a preorder/deposit app. It gives you a polished customer experience without having to build the entire workflow yourself.

If instead it's:

Product is technically “out of stock” → keep accepting orders → maintain a controlled queue/backorder quantity → show expected fulfillment date

I'd take a close look at BigCommerce, because its current backorder functionality is unusually relevant to that model. BigCommerce

If you tell me your typical production time (e.g. 4 weeks vs. 4 months), whether you want full payment or deposits, and whether customers can order multiple items with different lead times, I can narrow this down to the best platform/workflow for your boutique.
