BigCommerce has spent years positioning itself as the more B2B-native option among the big general-purpose ecommerce platforms — it ships more wholesale functionality out of the box than most competitors, and its B2B Edition product is a genuine, purpose-built attempt at the problem. That makes it a fair comparison for a platform like Haize, which is wholesale-first by design rather than by add-on. Here's how they actually differ.
Native B2B features
BigCommerce's B2B Edition includes real wholesale primitives: customer groups with different price lists, quote requests, purchase-order-style workflows, and multi-buyer company accounts (one company login, multiple authorized purchasers). This is a genuine strength — it's more B2B functionality natively than Shopify or WooCommerce ship without third-party apps, and if your wholesale logic maps cleanly onto "company account with a price list," it's a well-trodden path with real documentation behind it.
Haize's RFQ and quoting flow covers the same core need — a buyer requesting a quote rather than checking out instantly — built into the platform rather than a separately-licensed edition. The two aren't identical in scope: BigCommerce B2B Edition's multi-buyer company-account model is more elaborate than what a single-storefront RFQ flow needs to be for most wholesale brands. If your buyers are genuinely large organizations with multiple authorized purchasers under one account, that's a place BigCommerce's model has more built-in structure today.
Who builds and maintains the store
BigCommerce, like Shopify, is a platform you (or a hired developer/agency) build on: pick a theme, configure B2B Edition's settings, integrate the apps you need from its marketplace. It's a smaller app ecosystem than Shopify's but still meaningfully sized, and BigCommerce's API-first architecture is often cited as a strength for teams that want a headless or custom front end.
Haize's model removes the build step entirely — you submit a brief and get a hosted, wholesale-ready storefront on your own domain, without configuring theme settings or B2B Edition modules yourself. That's a real trade of control for speed: BigCommerce's flexibility (headless options, deep API access, granular B2B Edition configuration) is worth more the more custom your requirements are; Haize is worth more the more you'd rather not be the one configuring it.
Running multiple brands
BigCommerce's multi-storefront capability (available on its higher plan tiers) lets you run several storefronts from shared catalog data, which is architecturally similar in spirit to Haize's multi-brand-from-one-backend model. The practical difference is mostly about what's included at what price point: BigCommerce's multi-storefront tooling generally sits on higher-tier plans, where Haize's multi-brand support is part of the same platform you're already using for one brand. If you're only running a single storefront, this isn't a differentiator either way.
Shipping
BigCommerce supports multiple shipping carriers and rules, generally configured per store rather than deeply differentiated per brand within a multi-storefront setup — the granularity depends on plan tier and app support. Haize's per-site carrier configuration is a platform-level feature meant specifically for the multi-brand case: each storefront's shipping rules are its own, without needing a higher plan tier to unlock it.
Cost and complexity
BigCommerce's pricing is usage-based (revenue thresholds move you between tiers) plus B2B Edition access at the relevant tier, plus whatever apps you add. It's transparent in the sense that BigCommerce publishes its tiers, but the total cost of a fully-configured B2B storefront is still the sum of plan tier, B2B Edition, and app subscriptions. Haize bundles wholesale quoting, hosting, and multi-brand support into the base offering rather than tier-gating them, which simplifies the cost picture at the expense of the configurability those higher tiers unlock.
Where BigCommerce is the better call
If you want native, elaborate B2B account structures (multi-buyer companies, detailed price lists per customer group), headless/API-first flexibility, or you're planning custom development on top of the platform — BigCommerce's B2B Edition is a serious, purpose-built product, not an afterthought, and its API-first design is a genuine advantage for teams with development resources who want that level of control.
Where Haize is the better call
If you want a wholesale storefront live without configuring B2B Edition modules yourself, you're running multiple brands and want shared backend operations without separately licensing multi-storefront tooling, or you'd rather have quoting and shipping work out of the box than assemble them from platform settings and apps — that's Haize's lane. Both platforms take B2B seriously; the difference is mostly build-it-yourself with more configuration surface versus done-for-you with less.
