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

The Skeptic

Weighted verdict

Knows the headline price is never the invoice here. Reads for the transaction fee, the apps that turn out to be mandatory, the hosting nobody mentioned, and what the platform charges to let a merchant leave with their own order history.

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

Scored by The Skeptic

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 Skeptic

Variant counts are priced into the plans and the payment breadth is real — invoice, direct debit, cash on delivery and prepayment alongside a dozen marketplace payment types — but every provider is installed as a plugin from the marketplace, and we found no public information on what those plugins cost or on guest checkout, bundles, tiered pricing or voucher rules. 2 5 6

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 Skeptic

The German accounting scaffolding is evidenced — GOBD-compliant invoices, a procedural-documentation and GDPR section, SEPA mandate and EBICS setup — but the only VAT mechanics shown are an analytics figure computed as gross minus net per order line. We found no public information on VAT-ID validation, reverse charge, OSS tracking or the mandatory checkout elements German law imposes. 1 6 7 8

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 Skeptic

A documented REST API with rights granted per module and sub-module, tutorials and bulk routes, plus a plugin marketplace open to third-party uploads free of charge and plugin sets that can be tested before going live — that is a working developer surface. We found no public information on a headless storefront API, webhooks or documented rate limits. 9 10

Report an error

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 Skeptic

The back office is broad: order search, group functions and custom views, stock across up to ten warehouses with a mobile app, POS, automated order processing and 150+ marketplace channels, with returns visible as return-reason analytics and credit notes deducted from VAT totals. We found no public information on partial shipments, dropshipping or maintained interfaces to named ERP and accounting systems. 1 2 8 11

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 Skeptic

Export comes in two shapes — a free CSV plugin covering product, warehouse and order data, and REST retrieval of contacts and orders — but hosting is the vendor's cloud and we found no public information on self-hosting, a documented migration path, deletion or a data-return commitment. Data syncs are metered per plan at 5,000 to 50,000 per day, the same quota a full migration export would draw on. 1 2 9 13 14

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 Skeptic

The imprint pins the contracting entity in Kassel, Germany, but the platform is sold as cloud-native and we found no public information on where that cloud runs, who owns the vendor, or which subprocessors sit in a checkout whose payment methods route through marketplace plugins. A downloadable privacy statement and a data-protection contact address are the extent of what the captured pages show. 1 3 5

Report an error

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 Skeptic

Unusual openness on limits: four monthly tiers from 'Ab 59€ / Monat' to 'Ab 229€ / Monat', stated net plus VAT, with SKU, user, warehouse and monthly revenue caps all public and a trial requiring no credit card. But the invoice is still not computable — the model bills on average monthly GMV with only 10.000 Euro included and the pricing page references calculation details without giving the rate, Ultimate is 'Auf Anfrage', and we found no public information on transaction fees, payment-plugin prices or the cost of the plentyBI editions. 2 5 8

Where this could be wrong

Evidence ages. The oldest capture behind this page is from 16 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. Not confirmed on the vendor’s own pages as captured.
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.
