The B2B Seller

Weighted verdict

Sells to businesses across the EU: net prices, VAT-ID validation, reverse charge, customer-specific price lists and payment on account. Reads a shop that shows gross prices to a trade customer as one that has not met a trade customer.

Same scores as the panel view — this lens weights them the way this judge cares.

Scored by The B2B Seller

Catalogue & checkout

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 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

Tax & German legal correctness

How this is scored

VAT determination, OSS, B2B reverse charge, and the checkout requirements German law actually imposes — judged on what the platform does, not on a plugin someone could buy.

0 — A single VAT rate applied everywhere; no B2B handling, no country logic, no legal-text handling in checkout.

3 — Per-country VAT rates configurable by hand, net prices for B2B possible with effort, and legal texts as free-form pages.

5 — Automatic VAT by destination and customer type, VAT-ID validation with reverse charge, gross and net display per customer group, and the mandatory checkout elements (order button wording, withdrawal policy, price indications) handled.

8 — OSS thresholds tracked and reported, correct invoicing per case including reverse-charge notes, small-business and third-country handling, and e-invoicing (XRechnung/ZUGFeRD) for B2B orders.

10 — Tax and legal correctness are maintained by the vendor rather than the merchant: rates and thresholds updated as the law moves, OSS reporting produced, every invoice case correct out of the box, and documented conformity a lawyer could review.

Report an error

The B2B Seller

Zones by country, subdivision and postal code, with inclusive or exclusive price display per customer group, get a shop to net prices for trade buyers — but the rates themselves are configured by hand via the tax API. We found no public information on VAT-ID validation with reverse charge, OSS thresholds and reporting, e-invoicing formats, or the German checkout requirements such as order-button wording and withdrawal policy, which is the core of my test. 5 6

Extensibility & developer surface

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 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

Order operations & back office

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 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

Data ownership & exit

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 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

European sovereignty

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 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

Pricing transparency

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 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. Credit where due: the free trial with no credit card and the stated absence of payment fees for 20+ embedded providers are public, but we found no public information on tier prices, billing period, order limits or the actual PayPal card processing rates. 1 4 11

European sovereignty — proven facts

1 of 4 dimensions proven

Built only from facts shown on the vendor's own pages. A dimension we could not prove is left open, not scored as zero.

Where this could be wrong

Evidence ages. The oldest capture behind this page is from 29 Sep 2026. Vendors change pricing and policies without notice; every fact reflects its source as of the capture date shown in the registry.
Weak sourcing — Subprocessors. Google Cloud Platform appears only as a trust-center section heading under Infrastructure rather than in the subprocessor list or DPA (both exist as document categories but their contents were not captured), and no server region is stated
AI can misread a source. Extraction and judgement are automated; a citation guarantees traceability, not infallibility. If something here is wrong, say so — no account needed, every report is decided within 5 business days, and accepted corrections are published.
