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

The Data Protection Officer

Weighted verdict

The shop holds customers, addresses and buying histories, and the checkout is full of third parties. Wants the subprocessor list, consent handling that survives a complaint, deletion that executes against order history, and an answer on where the CDN and analytics sit.

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

Scored by The Data Protection Officer

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 Data Protection Officer

Payment is the strong part: invoice, direct debit and prepayment are documented, methods arrive as plugins from the marketplace, can be permitted or discounted per customer class, and plugin sets let each webshop run its own payment line-up. We found no public information on guest checkout, bundles, tiered product pricing or promotion rules, so it sits below the fully featured level. 5 6 10 2

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 Data Protection Officer

The developer surface is real: a documented REST API with rights granted separately per module, bulk routes and tutorials, free plugin uploads to the marketplace, and plugin sets that can be tested before going live even on a single channel. We found no public information on a headless storefront API, webhooks for order events or documented rate limits, which keeps it out of the upper group. 9 10

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 Data Protection Officer

Order handling shows search, configurable columns, group functions and an unpaid-amount total, backed by multi-warehouse stock up to ten warehouses with a mobile app, automated workflows, a returns-reason dimension in reporting and a POS offering. We found no public information on named carrier integrations, partial shipments, dropshipping or maintained ERP interfaces, which is where the bar sits higher. 11 1 2 8 6

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 Data Protection Officer

Export is genuinely documented: CSV of product, warehouse and order data that can be revised and re-imported, custom data formats via a designer plugin, and REST access to all contacts and orders in bulk, with documentation on cleansing and backups. But we found no public information on a documented deletion procedure, a stated data-return commitment or self-hosting, and the platform is cloud-native on the vendor's own stack, so an exit rests on export alone. 13 14 9

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 Data Protection Officer

The contracting entity is plainly European — a German company in Kassel with a German-language privacy contact and a downloadable data protection statement — and the pages claim audit-ready and EU-compliant without a published certificate behind it. We found no public information on where the shops are hosted, and no subprocessor list at all, which matters when payments, shipping and customer communication all arrive as third-party plugins into the checkout. 3 4 5 1

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 Data Protection Officer

Four tiers are priced publicly with monthly billing, net-of-VAT treatment stated, per-tier caps on SKUs, users, warehouses, syncs and monthly revenue, and the model disclosed as plan plus average monthly GMV with 10,000 Euro per month included at the start. For full computability the gap is that the pricing beyond the included GMV sits behind a details page we could not see, the top tier is on request, and we found no public information on transaction fees or the cost of the payment and export plugins. 2 1
