Read this page as one judge. Each weighs the same scores by what they care about.

The Operations Lead

Weighted verdict

Ships the orders and handles the returns. Wants stock that is true across channels, partial shipments, carrier integrations with labels, and an ERP link the vendor maintains. A shop that cannot do a partial refund is a shop that has never had December.

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

Scored by The Operations Lead

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 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

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 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

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 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

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 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

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 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. Ltd., a corporate form outside the EU, and the single point is for published privacy materials such as a Data Protection Officer and an international transfer whitepaper. 2 4

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 Operations Lead

The only cost facts on the captured pages are a free trial with no credit card and no payment fees for orders processed through the 20+ embedded payment providers, with PayPal rates described only as pre-negotiated and decreasing as you grow. We found no public information on plan prices, billing periods, order or revenue limits, minimum terms or VAT treatment, so a merchant cannot compute the annual invoice from public pages. 1 4
