BigCommerce vs Shopify: how to choose for a growing catalog

BigCommerce and Shopify are the two hosted platforms most often compared for stores that have outgrown a basic website builder. They overlap more than they differ: both host your store, take payments, handle checkout and support a large catalog. The choice usually comes down to how your products are structured, how much you want built in versus bolted on, and who you will hire to help.

Plan names, prices and fee terms move. Everything here was checked against official sources at the time of writing; confirm current pricing and limits before you commit.

BigCommerce vs Shopify at a glance

Here is the quick view. Details follow.

If a row reads vaguely, that is deliberate: BigCommerce restructured its plans in 2026 and the live pricing page is the only source worth trusting for current numbers.

Who each platform suits

BigCommerce is a good fit if:

• Your products have a lot of option dimensions, with four, five or six independent options.
• You want features such as advanced product options, multi-storefront or B2B tooling available from the platform itself, with fewer apps.
• You have a developer or agency comfortable with its APIs and its theme system.
• You prefer to pay for a platform that does more by default.

Shopify is a good fit if:

• You want the widest choice of themes and apps and the easiest time hiring people who know the platform.
• Your variants are large grids on three options or fewer, such as size, colour and material.
• You sell through several channels and want those integrations to be well supported.
• You value simplicity in the admin for non-technical staff.

For many stores either works. The deciding factor is often who will operate it day to day.

Catalog size, options and variants

BigCommerce documents up to 600 SKUs per product and 250 values per option. An older community thread mentioned 250 variants per product; a BigCommerce representative in that thread described 600 as the limit for stores not using Multi-Storefront, so confirm your own setup if you use it. For products that need more than 600 combinations, BigCommerce recommends modifier options, which have no limit on count but do not get their own SKUs or separate inventory tracking, or splitting the parent product.

Shopify supports up to 2,048 variants per product, announced in its developer changelog in October 2025, with a maximum of three options. A few older apps and themes assume the former 100-variant ceiling, so test anything you rely on.

The trade-off is plain. If your product needs four or more independent options and fewer than 600 combinations, BigCommerce fits the structure natively. If you need a huge matrix on three options, Shopify gives you more room. On Shopify, a fourth dimension means combining options, splitting products or using an app.

Neither limit is likely to matter for a typical fashion, home or beauty catalog. Check your single most complex product.

Built-in features vs apps

This is the real philosophical difference. BigCommerce has historically put more into the core platform, such as product options, customer groups with group pricing and some B2B functions. Shopify keeps the core lean and expects you to extend it, which is why its app store is so large.

Each approach has costs. Built-in features mean fewer subscriptions and fewer integration points. Apps mean choice and speed of innovation, but monthly fees add up and each one is another thing that can conflict or slow the storefront. If your requirements are specific, list them first and check, for each platform, whether it is native, an app or custom work. That exercise is more useful than any feature-count comparison.

Both platforms offer headless and API-led options if you want a custom front end. That is a larger project on either, and it changes the cost equation.

Plans, payments and fees

BigCommerce's plans have historically been tiered by annual online sales rather than only by features, and the vendor revised plan names and terms in 2026. Search results for its current pricing describe a move to new plan names, trailing twelve-month sales thresholds and a fee for some stores that use non-embedded payment providers. Because that was a recent change and the pages are in flux, I will not quote numbers here. Open the live pricing page and read the terms for your expected sales volume, particularly what happens when you pass a threshold.

Shopify's plans are tiered by features and staff seats. At the time of writing its pricing page lists Basic, Grow and Advanced, plus Plus for larger merchants. If you use a third-party payment provider rather than Shopify Payments, Shopify adds a fee on each order: 2% on Basic, 1% on Grow, 0.6% on Advanced and 0.2% on Plus. Staff accounts increase with plan level.

To compare honestly, model one year at your expected revenue. Include the plan, the payment fee on your chosen provider, the apps or add-ons you would need and any developer time. A store that sits near a BigCommerce sales threshold should model both the current and next tiers.

SEO basics

Both platforms provide editable titles and meta descriptions, customisable URLs, sitemaps, redirect tools, structured data support through themes and SSL. Neither will rank your store by itself. Product titles, descriptions, internal linking and site speed matter more than the platform.

One real difference is the URL structure. Shopify uses fixed prefixes such as /products/ and /collections/. BigCommerce has more flexible URL patterns. That matters when you migrate, because each old URL has to point to a new one, and fixed prefixes mean almost every URL changes.

Migrating between them

Moving from BigCommerce to Shopify is a well-trodden route. Products, variants, images, customers and collections can be exported and mapped to Shopify's product CSV format or moved with third-party migration apps that list BigCommerce as a source. Shopify's own Store Migration app lists a limited set of sources, so check whether BigCommerce is supported in your admin before relying on it.

Things to plan for:

1. Option structure. If any product uses more than three options, decide how to restructure it before import.
2. Variant limits and modifiers. BigCommerce modifier options have no SKU. They need to become variants, line item properties or an app on Shopify.
3. Redirects. Map every old URL with traffic or backlinks to its new one and load the 301s before launch.
4. Orders and customers. These usually need a separate tool and a decision on how much history to carry.
5. Custom features. Group pricing, custom fields and checkout logic may need an app or rebuild.

If it helps, we cover the product data side with our BigCommerce to Shopify migration service, and if you are staying on BigCommerce and need a large range loaded, there is the BigCommerce product upload service. Our Shopify bulk product upload guide covers the Shopify CSV format in detail.

When to do it yourself and when to hand it off

Choosing a platform is yours to do, and a trial of each takes an afternoon. Load a handful of your hardest products and see which option model fits.

For a migration, a small catalog with simple variants is a fair DIY job. Hand it off when volume, restructured options, supplier data in poor shape or a launch date make mistakes expensive. We use an AI engine for the volume and a person reviews every output, and you approve before anything goes live. Turnaround starts from 48 hours for eligible projects; turnaround depends on scope, catalog complexity and the quality of the data and access we receive. We never ask for store passwords and work through a staff account you can remove. See pricing, or ask for a free 10-product sample and we will tell you plainly whether it is a fit.

A short decision path

1. Do your products need four to six independent options? BigCommerce fits that natively.
2. Do you want the biggest app, theme and agency pool? Shopify.
3. Do you have strong B2B requirements? Compare the current feature sets against your list, on both.
4. Is your team non-technical and handling the store daily? Shopify's admin is generally the easier hire-and-train option.
5. Unsure? Trial both with your worst product and your simplest, and compare how each feels.
