The panel's verdict

BigCommerce is strongest on catalog and checkout and extensibility: the judges found a one-page checkout that can be forked on GitHub with full source access, digital wallets, one-click and buy-now-pay-later, customer-group pricing, account-specific catalogs and B2B invoicing, plus REST and GraphQL APIs across storefront, admin, account and B2B with downloadable OpenAPI specs. It is weakest on sovereignty and pricing transparency: the vendor is BigCommerce, Inc. with copyright held by BigCommerce Pty. Ltd., hosting appears as a Google Cloud Platform heading with no server region stated, the subprocessor list was not captured, and the captured pages show no plan price — the public cost facts are a free trial without a credit card and no payment fees through 20+ embedded providers. Tax and legal sits at 4, with hand-configured rates and no public information on VAT-ID validation, reverse charge or OSS. The judges split on operations: the B2B seller scored 7 for multi-channel order intake and 600+ integrations; the operations lead scored 4, finding no named vendor-maintained interface and returns only as third-party apps.

Report an error

Speaks for it

  • A one-page checkout that can be forked on GitHub with full source access, shipping digital wallets, one-click, and buy-now-pay-later.
  • Account-specific catalogs, customer-group pricing, purchase orders, and B2B invoicing at checkout.
  • REST and GraphQL APIs across storefront, admin, account, and B2B, with downloadable OpenAPI specs and headless starter solutions.
  • No payment fees for orders processed through 20+ embedded payment providers.
  • A migration app documented for up to 500,000 product, customer, and order records.

Report an error

Held against it

  • Tax rates configured by hand, with no public information on VAT-ID validation, reverse charge, OSS reporting, or e-invoicing.
  • Hosting on Google Cloud Platform with no server region stated and a subprocessor list whose contents were not captured.
  • No plan price on the captured pages, with PayPal card rates described only as pre-negotiated.
  • Migration documented inbound only, with no public information on export completeness or a data-return commitment.
  • Returns appearing only as a marketplace category of nine apps, with no public information on partial shipments or carrier label printing.

Report an error

Best for

  • You sell to business buyers and need account-specific catalogs, customer-group pricing, and purchase orders or invoice payments at checkout.
  • Your team wants to build and own the storefront, using a forkable checkout and REST and GraphQL APIs with downloadable OpenAPI specs.
  • You sell across channels — marketplaces such as Amazon, Walmart, and eBay, point of sale, and multiple storefronts.
  • You are moving in from Shopify, WooCommerce, or Adobe Commerce (Magento) and need a documented import of up to 500,000 records.

Report an error

Avoid if

  • You need vendor-handled German or EU tax correctness — the documented tax mechanism is manual rate configuration, with no public information on VAT-ID validation, reverse charge, or OSS reporting.
  • Your procurement requires an EU contracting entity or a stated server region — the vendor is BigCommerce, Inc., the copyright holder is BigCommerce Pty. Ltd., and hosting appears as Google Cloud Platform without a region.
  • You must budget from published prices — the captured pages show a free trial and the absence of payment fees, but no plan price, billing period, or order limits.
  • You need returns processed in the system rather than through marketplace apps — returns appear as a nine-app category.

The scores

Catalogue & checkout

Show reasoning
How this is scored

Products, variants, pricing rules and the path to payment — the part that either converts or does not.

0 — Flat product list with one price and no variants; checkout is a form and one payment method.

3 — Variants and categories with a standard checkout and two or three payment methods, but no bundles, no tiered pricing and no guest checkout worth the name.

5 — Full variant matrix, product bundles, tiered and customer-group pricing, guest checkout, and the payment methods a German shop needs including invoice and direct debit.

8 — Configurable products, per-channel pricing, promotions and vouchers with rules, a checkout that can be customised without a rebuild, and payment via the major providers plus buy-now-pay-later where offered.

10 — Merchandising and checkout are the product: rule-driven pricing and promotions, A/B-testable checkout, multi-currency and multi-language as standard, and conversion features (abandoned cart, one-page checkout) shipped rather than bolted on.

Report an error

The Merchant

This is the checkout I want to sell on: optimized one-page checkout, no-code controls in the control panel for branding and guest checkout behaviour, full source access and a GitHub fork of the checkout, plus digital wallets, one-click, buy-now-pay-later and B2B invoicing among 250+ payment methods, with abandoned-cart email recovery and checkout upsells shipped. I found no public information on product variants, bundles or tiered pricing, and direct debit is not named among the methods, which is what holds this back from the very top. 1 3 4

Report an error

The B2B Seller

This is a shop that has met a trade customer: account-specific catalogs and pricing, customer-group pricing, purchase orders and B2B invoicing at checkout, plus a one-page checkout with wallets, BNPL and shipped abandoned-cart recovery, multi-currency and multi-language. I stop just short of the top because we found no public information on a configurable-product variant matrix, voucher rules engines or A/B testing of the checkout. 1 3 4

Report an error

The Developer

One-page checkout with wallets, one-click and BNPL, abandoned-cart recovery shipped rather than bolted on, multi-currency and multi-language as standard, plus customer-group and account-specific pricing and promotions in checkout — and a checkout that can be forked on GitHub with full source access rather than reskinned in a closed editor. I found no public information on A/B-testing the checkout or on native bundles and tiered quantity pricing. 1 3 4

Report an error

The Operations Lead

One-page checkout, abandoned-cart recovery, digital wallets, one-click and buy-now-pay-later are shipped features on the product pages, and customisation goes as far as forking the checkout on GitHub with full source access; customer-group and account-specific pricing are documented alongside multi-currency with real-time exchange rates and multi-language. We found no public information on variant matrices, bundles, tiered pricing or A/B-testable checkout, which is what keeps this short of the very top. 1 3 4

Report an error

The Data Protection Officer

The captured checkout pages show a one-page checkout that can be forked on GitHub with full source access, BNPL, digital wallets and one-click, plus customer-group pricing, account-specific catalogs, promotions and upsells inside checkout, and abandoned-cart email recovery shipped alongside multi-currency and multi-language. We found no public information on an A/B-testable checkout or a rule-driven promotions engine, which is what keeps this off the top band. 1 3 4

Report an error

The Skeptic

One-page checkout, wallets, one-click and buy-now-pay-later are all public, and the checkout can be forked on GitHub with full source access and a SDK — that is customisation without a rebuild, which I rarely get to say. Pricing rules run to customer-group and account-specific pricing with promotions and upsells inside checkout; I found no public information on product bundles or A/B-testable checkout variants. 1 3 4

Extensibility & developer surface

Show reasoning
How this is scored

Themes, apps, APIs and headless — whether the shop can be shaped to the business, and at what cost in lock-in.

0 — Fixed templates, no app ecosystem, no API.

3 — Theme editing within limits and a small app store; a read-mostly API and no local development story.

5 — Custom themes with a template language, an app or plugin ecosystem, a documented REST API, and webhooks for the core order events.

8 — Full storefront API for headless builds, an extension framework with its own lifecycle, staging environments, version control for themes, and documented rate limits.

10 — A platform a team can own: headless-first APIs, open-source or source-available core, plugin architecture with a real dependency model, local development and CI supported, and upgrade paths that do not orphan customisations.

Report an error

The Merchant

The developer surface is broad and public: REST and GraphQL APIs across storefront, admin and B2B, downloadable OpenAPI specs, headless starter solutions, a documented session-sync rate limit, and full source access to the checkout — a shop a team can shape without a rebuild. I found no public information on staging environments as a platform feature, version control for themes or webhooks for order events, which keeps it one tier below the best-in-class surface. 7 8 3 4

Report an error

The B2B Seller

A full GraphQL storefront API alongside REST with downloadable OpenAPI specs, JWT session sync for headless logins, and a checkout whose source I can fork on GitHub is a surface a team can build a proper B2B portal on. We found no public information on staging environments, documented API rate limits or version control for themes, so I settle at the level below the top. 3 7 8

Report an error

The Developer

The strongest developer surface on these pages: GraphQL and REST storefront APIs with downloadable OpenAPI specs, headless starter solutions, MCP servers, and a checkout that can be forked on GitHub with full source access. Catalyst ships as versioned packages, which gives the storefront layer a real upgrade cadence, but I found no public information on version control for the theme system itself, a plugin dependency model, staging environments outside third-party app categories, or documented API rate limits. 2 3 7 8 12

Report an error

The Operations Lead

REST and GraphQL surfaces across storefront, admin, account and B2B with downloadable OpenAPI specs, headless starter solutions, a WordPress plugin, Catalyst packages at published versions, and a checkout you can fork — a development team can genuinely own the storefront. Staging appears only as an app-marketplace category, and rate limits are spelled out only for session sync rather than for the APIs generally. 2 3 7 8

Report an error

The Data Protection Officer

There is a genuine headless surface — REST and GraphQL APIs across storefront, admin, account and B2B, downloadable OpenAPI specs, starter apps, and a checkout a team can fork and rebuild — which sits well above a basic plugin shop. We found no public information on staging environments, on documented rate limits beyond the session-sync lockout, or on version control for themes, so this stops short of the top band. 3 7 8

Report an error

The Skeptic

GraphQL and REST surfaces across storefront, admin, account and B2B, downloadable OpenAPI specs, headless starter solutions, MCP tooling and a checkout you can fork — a developer surface a team can actually work with. I found no public information on staging environments, documented rate limits or a local development story beyond two staging apps in the marketplace. 3 7 8 12

Order operations & back office

panel disagrees Show reasoning
How this is scored

What happens after checkout: order management, stock, returns, shipping, and the link to ERP or accounting.

0 — An order list and an email; stock is a number nobody trusts, returns are manual.

3 — Order statuses and basic stock, one shipping integration, and returns handled by hand.

5 — Order workflow with partial shipments, multi-warehouse stock, named carrier integrations with label printing, and a returns process in the system.

8 — Multi-channel order intake, automated fulfilment routing, supplier and dropshipping flows, and maintained interfaces to named ERP and accounting systems.

10 — The shop is the front of an operation: real-time stock across channels and warehouses, returns and refunds fully worked including partials, ERP integration the vendor maintains, and operational reporting a merchant runs the business from.

Report an error

The Merchant

Native operations cover the shipping side well — real-time carrier quotes, flat-rate and value-based rates, multi-address shipping, POS stock sync and buy-online-pick-up-in-store — and reach into ERP, WMS and 3PL through 600+ integrations is real breadth. Returns processing and much of order management arrive as marketplace apps rather than in the system, and I found no public information on partial shipments, carrier label printing or dropshipping flows. 9 10 3 1

Report an error

The B2B Seller

Multi-channel order intake from marketplaces, point of sale and multiple storefronts with inventory, customers and orders synced everywhere you sell, plus 600+ ERP, CRM, PIM and WMS integrations and 3PL connections, is a real back office. Returns appear only as an app category rather than a process in the system, no ERP or accounting system is named, and we found no public information on partial shipments, supplier and dropshipping flows or carrier label printing. 1 3 9 10

Report an error

The Developer

Multi-channel intake is real — marketplaces, multi-storefront and 150+ sync channels — and the Shipping Manager does real-time carrier quotes, flat and weight-based rates, with 3PL, warehouse and fulfilment-centre connections plus integration categories for ERP, CRM, PIM and WMS. Returns appear only as third-party apps, and I found no public information on partial shipments, multi-warehouse stock, dropshipping or named ERP and accounting systems. 1 3 9 10

Report an error

The Operations Lead

What the pages show is shipping setup with real-time carrier quotes and named rate tools — ShipperHQ, Advanced Shipping Manager, GlobalE — a point-of-sale inventory sync claim, marketplace and multi-storefront selling, and an integration count of 600+ across ERP, CRM, PIM and WMS without a single named, vendor-maintained interface. We found no public information on partial shipments, partial refunds, label printing or multi-warehouse stock, and returns appear only as a category of nine third-party apps rather than a process in the system. 1 3 9 10

Report an error

The Data Protection Officer

Multi-channel intake is well evidenced — marketplace listings, point-of-sale sync, multi-storefront, 3PL and warehouse-system connections, and a Shipping Manager with real-time carrier quotes and location-based methods. Returns surface only as a nine-app marketplace category, and we found no public information on partial shipments or carrier label printing; from my seat, order data running through that many third-party apps also spreads customers' personal data across the chain. 1 3 9 10

Report an error

The Skeptic

The shipping story is broad — real-time carrier quotes, 3PL, OMS/WMS connections, BOPIS, cross-border duties and customs documentation — with 600-plus ERP, CRM, PIM and WMS integrations claimed at category level and multi-channel intake from marketplaces and point of sale. But returns sit in a nine-app marketplace category rather than an evidenced native process, and I found no public information on partial shipments, automated fulfilment routing or ERP interfaces the vendor maintains. 1 9 10

Data ownership & exit

Show reasoning
How this is scored

Whether the catalogue, customers and order history remain the merchant's: export completeness, hosting choice, and what leaving actually costs.

0 — Export is a partial CSV; order history and customer records cannot leave intact, and hosting is the vendor's alone.

3 — CSV export of products and customers, order history partial, no self-hosting, no documented migration path.

5 — Complete export of catalogue, customers and orders via API or dump, documented deletion, and a stated data-return commitment.

8 — Full-fidelity export including media and order documents, self-hosting or a choice of hosting partner, and no metering that prices a migration out of reach.

10 — Ownership is structural rather than promised: open-source or source-available platform the merchant can run anywhere, database-level access, documented migration in both directions, and contractual data return.

Report an error

The Merchant

Moving in is documented in detail — a migration app handling 500,000 product, customer and order records, post-import error reporting, and a data-erasure module in the security program. The way out is not: I found no public information on full export of catalogue, customers and order history, a stated data-return commitment, self-hosting or a documented exit path, so what leaving actually costs cannot be judged. 11 12 2

Report an error

The B2B Seller

The way in is well documented — a migration app and services transferring up to 500,000 product, customer and order records with post-import error reporting — and data erasure and backups are named modules. But the captured pages document entry, not exit: we found no public information on complete export of catalogue, customers and order history, a data-return commitment, or self-hosting. 2 8 11

Report an error

The Developer

Migration is documented in one direction only — into the platform from Shopify, WooCommerce and Magento with a 500,000-record transfer limit — while the security programme names data erasure and backups. I found no public information on export completeness, self-hosting or a documented path out, which is the number that tells me what a five-year commitment actually costs. 2 8 11

Report an error

The Operations Lead

Every migration fact points inward — a migration app, premium migration services, agencies, 500,000 product, customer and order records, post-import error reporting — while the public APIs and a named Data Erasure module in the trust centre are the only outward-facing pieces. We found no public information on export completeness, a documented way out, self-hosting, or a data-return commitment. 2 8 11 12

Report an error

The Data Protection Officer

Moving data in is documented — 500,000 product, customer and order records via a migration app — and Data Erasure is listed as a security module heading, but we found no public information on export completeness, on deletion executing against order history, or on a data-return commitment. Hosting is on the vendor's Google Cloud platform with no alternative offered, so the pages captured do not document what leaving actually costs. 2 11 12

Report an error

The Skeptic

Everything public about moving data is about arriving: a migration app, premium migration services and agencies for up to 500,000 product, customer and order records in, plus 28 migration-service apps and a Data Erasure module in the trust center. I found no public information on outbound export fidelity, self-hosting, or any commitment — let alone price — for leaving with your own catalogue and order history. 2 11 12

European sovereignty panel opinion

Show reasoning
How this is scored

Where customer and order data live, who the contracting entity is, and which subprocessors sit in the checkout path. Independently sourced by the sovereignty pipeline.

0 — Non-EU vendor and contracting entity, hosting unstated or non-EU, subprocessors unnamed.

3 — EU hosting offered as an option while the contracting entity is non-EU, or the subprocessor list is absent.

5 — EU hosting as standard and an EU contracting entity, but parts of the chain — CDN, analytics, payment routing, support tooling — are non-EU without an explained safeguard.

8 — EU hosting on named infrastructure, EU contracting entity, complete subprocessor list published, any non-EU processing named with its legal basis.

10 — Sovereign end to end and evidenced: vendor, entity, hosting and every subprocessor European, certification published, and a self-hosted option that puts the shop entirely under the merchant's control.

Report an error

The Merchant

No server region is stated — infrastructure is Google Cloud Platform with no location given — and although a trust center lists Subprocessors and a Data Processing Agreement as document categories, their contents were not captured, so no subprocessor names and no safeguard against US legal access are visible.

The B2B Seller

The vendor is BigCommerce, Inc. with the copyright held by BigCommerce Pty. Ltd., and we found no public information on an EU contracting entity, EU hosting or any server region — hosting appears only as a Google Cloud heading. The subprocessor list and data processing agreement exist as document categories whose contents were not captured, leaving an unexplained US CLOUD Act exposure in the checkout path, which for my EU trade customers puts this at the bottom. 2 11

The Developer

The pages name Google Cloud Platform as infrastructure with no server region stated, the copyright entity is BigCommerce Pty.

The Operations Lead

No server region is stated anywhere, the only hosting reference is a Google Cloud Platform heading in the trust centre, and the subprocessor list exists as a document category whose contents were not captured. The footer entity is BigCommerce Pty.

The Data Protection Officer

The vendor is BigCommerce, Inc. with copyright held by BigCommerce Pty. Ltd., hosting runs on Google Cloud Platform with no server region stated, and the subprocessor list exists only as an uncaptured document heading — so with 20+ embedded payment providers in the checkout we cannot see where a single one of them processes. Data-protection artefacts such as a DPO contact, a transfer impact summary and an international transfer whitepaper exist as headings, but we found no public information on EU hosting, an EU entity, or where CDN, analytics and payment routing sit, and the US cloud provider in the chain raises Cloud Act exposure. 1 2 4

Pricing transparency

Show reasoning
How this is scored

Whether a merchant can compute the real annual cost — licence, transaction fees, apps, hosting — from public pages alone. The category where the headline price is least often the invoice.

0 — No public prices at all; every tier is a sales conversation.

3 — A monthly headline exists, but transaction fees, mandatory apps or hosting costs are unstated — the invoice is unknowable from the page.

5 — Tier prices public with billing period stated and transaction fees given, but at least one commonly needed piece (a required app, hosting, payment gateway rate) is unpriced.

8 — Every tier priced publicly including transaction or revenue-share rates, order or GMV limits, and the cost of the extensions most shops need; VAT treatment and minimum term stated.

10 — Complete price computability: annual cost derivable for a given order volume and GMV including licence, transaction fees, hosting and typical extensions — and for open-source platforms, an honest statement that the licence is free and where the money actually goes.

Report an error

The Merchant

No plan price appears on the captured pages — no monthly figure, no billing period, no order or revenue limits, no VAT treatment — so the real annual licence cost is not computable from public information. The few cost facts run the other way: a free trial without a credit card and no payment fees through 20+ embedded providers, while PayPal card rates are described only as pre-negotiated and volume-linked, without figures. 1 4 12

The B2B Seller

No plan price appears on the captured pages, so a merchant cannot compute the licence cost of an annual deal from public information — every tier is a sales conversation.
