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

The Billing Engineer

Weighted verdict

Wires billing into the product and gets paged when a webhook goes missing. Wants a documented API for usage events, idempotent webhooks, entitlements the app can read, a sandbox that behaves like production, and a migration path that moves subscriptions and payment tokens out again if the company outgrows the tool.

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

Plans, pricing models & subscription lifecycle

How this is scored

How the product models what is sold and to whom: plans, add-ons and price points, trials, upgrades and downgrades with proration, usage-based and seat-based pricing, contract terms and renewals, quotes, and a self-service portal where the customer changes or cancels their own subscription.

0 — No subscription model; recurring charges are set up by hand per customer or per invoice.

3 — A recurring invoice or a fixed plan that repeats on a schedule, but no proration, no trials, no add-ons and no usage component.

5 — Plans with add-ons and trials, upgrades and downgrades with proration, renewals and cancellations handled by the system, and a customer portal for viewing and changing the subscription.

8 — Usage-based, tiered, volume and seat-based pricing with metering through an API, contracts with minimum terms, ramps and notice periods, quotes that convert into subscriptions, multiple currencies and price books, and the subscription history kept per customer.

10 — The commercial model lives in the product: hybrid pricing (commitments, prepaid credits, overage) without custom code, price changes rolled out to existing customers with grandfathering, entitlements exposed to the selling application, and every change to a subscription versioned and attributed.

Report an error

The Billing Engineer

The documented model covers usage, seats, hybrid, minimums and credits with proration and amendments, real-time metering turned into billable metrics, a rich set of usage shapes (linear, graduated, volume, packaged, percentage-based), and CPQ that turns deal terms into a quote and contract, with credit grants, burndowns, rollover and overage available via API or dashboard. That clears the usage/tier/volume/seat bar with metering and quotes-to-contracts. We found no public information on grandfathering for price changes or entitlements exposed to the selling application, and the customer portal is for invoices, usage and credits rather than self-serve plan changes, so I stop short of the top. 1 5 6 12

Invoices & e-invoicing compliance

How this is scored

Whether the invoices the product issues are legally valid where the customer is: mandatory invoice content, sequential numbering, credit notes and cancellations instead of edits, retention and archiving to GoBD, and structured e-invoices (XRechnung, ZUGFeRD/Factur-X, Peppol) for business customers and public bodies.

0 — No invoices; the product charges cards or sends payment requests and the seller writes invoices elsewhere.

3 — PDF invoices from a template, but numbering, mandatory content, corrections and retention are not described.

5 — Invoices with sequential numbering and the mandatory content stated, credit notes and cancellations instead of edits, invoices in several languages and currencies, and a documented archive.

8 — Structured e-invoices to EN 16931 issued as XRechnung or ZUGFeRD/Factur-X and sent through Peppol, GoBD-compliant numbering and unalterable archiving stated, invoice data exportable for a tax audit, and the e-invoicing mandates in named EU countries addressed.

10 — Invoicing that stands up in any audit it may face: e-invoicing to public bodies and businesses in several EU countries with the channels named, clearance and reporting models (France, Italy, Poland) supported where they apply, a Verfahrensdokumentation or equivalent offered, and every invoice traceable to the subscription event that produced it.

Report an error

The Billing Engineer

Credit-note handling is properly engineered: create from an issued invoice or from scratch, edit line items until finalized, void, apply against invoices with a ledger balance, and an audit trail — corrections instead of edits. But we found no public information on sequential numbering, mandatory invoice content, archiving and retention for invoices, or structured e-invoices such as XRechnung, ZUGFeRD and Peppol, so it sits between templated PDFs and legally complete invoicing. 1 7 8 9

Cross-border VAT & tax handling

How this is scored

How the product gets tax right when the seller sells across borders: VAT rates per country and product type, reverse charge for business customers with VAT ID validation (VIES), the EU One-Stop-Shop, US sales tax — or, for a merchant of record, which tax liability it takes on in its contract and which it leaves with the seller.

0 — No tax handling; the seller types the rate on every invoice.

3 — One configurable VAT rate or a manual rate table, with no customer-location logic and no VAT ID check.

5 — Tax rates applied by customer country and status, reverse charge for business customers with a VAT ID field, and tax shown correctly on invoices and in reports.

8 — Automatic VAT per country and product type, VIES validation of VAT IDs, OSS reporting data, evidence of customer location kept, US sales tax through a named engine — or a merchant-of-record contract that states the tax liability it assumes and in which countries.

10 — Tax is discharged and evidenced: filings or filing data for OSS and the countries sold into, rate changes maintained by the vendor with a stated process, tax decisions per invoice explainable, and the division of liability between seller and vendor written into the terms.

Report an error

The Billing Engineer

Tax is applied per invoice line from the product's tax category, the customer's region and their tax status, with rates configurable per country and per individual US state, reverse-charge invoices marked as such with the customer's VAT number and no tax rates, and four named tax engines (Avalara, Anrok, Numeral, Sphere) for finer calculation and automated filing. We found no public information on VIES validation of VAT IDs or One-Stop-Shop reporting data, which is what holds this below the top. 9 10

Payment collection, dunning & portability

How this is scored

How invoices turn into money: which payment providers and methods the product works with, SEPA direct-debit mandates, automatic retries and dunning sequences, payment reconciliation, collections handover — and whether the seller can move subscriptions and stored payment details to another provider.

0 — No collection; invoices are sent and payment is chased by hand.

3 — One built-in payment provider with card payments, and failed payments reported but not retried or chased.

5 — Several payment providers or methods including SEPA direct debit with mandates, automatic retries of failed payments, dunning emails with configurable steps, and payments matched to invoices.

8 — Gateway-agnostic collection across named providers, smart retries and card updaters, dunning with escalation and service suspension rules, bank-transfer reconciliation, a handover to a collection agency, and recovery reported.

10 — Collection is portable and measurable: subscriptions and payment tokens importable and exportable with a documented migration path, routing across providers per country or method, recovered revenue reported per dunning step, and no lock-in to the vendor's own payment service stated in the terms.

Report an error

The Billing Engineer

Dunning is the strong part: reminder workflows with timing relative to the due date, branching on customer or invoice total, approval checkpoints, auto-stop when an invoice is paid, voided or written off, and a full audit trail — plus bank-transfer destinations (IBAN, UK transfer, ACH, wire, Swedish Bankgiro), Stripe and GoCardless connectors, portal payments via Stripe, and migration in from Chargebee, Maxio, Zuora and Stripe documented. We found no public information on SEPA direct-debit mandates, automatic retries of failed payments, or a documented path to move subscriptions and payment tokens out again, so it cannot reach the higher level. 1 5 8 11 12

Revenue reporting & accounting handoff

How this is scored

What finance gets out of billing: MRR, ARR, churn and cohort reporting, revenue recognition and deferred revenue, the export or sync to the accounting system and to DATEV, CRM and data-warehouse integrations, an API and webhooks, and a complete export of customer and subscription data.

0 — No reporting and no export beyond downloading individual invoices.

3 — A revenue overview and a CSV export of invoices, with no subscription metrics and no accounting integration.

5 — Subscription metrics (MRR, churn) on a dashboard, an export or sync to at least one named accounting tool, and a documented API with webhooks.

8 — Revenue recognition with deferred revenue schedules, a DATEV export or booking-ready journal for the ledger, native CRM and accounting integrations named, MRR movements explainable per customer, and a full data export documented.

10 — Billing is the system of record for revenue: recognition to IFRS 15 / ASC 606 stated, month-end close supported with reconciled reports, data-warehouse sync, audit trail of every financial event, and a complete export of customers, subscriptions and invoices that a successor system can import.

Report an error

The Billing Engineer

Recognition to ASC 606 and IFRS 15 in a dedicated sub-ledger, deferred-revenue and waterfall reports that reconcile to a journal report exportable for direct import into Xero, QuickBooks, NetSuite or a generic GL, direct posting to Xero, and named CRM, accounting and data-warehouse connectors. The API is versioned with a sandbox, and the webhooks come with HMAC signatures, 24-hour retries and explicit idempotency guidance — exactly what I want to wire against. We found no public information on MRR and churn dashboards or a complete, successor-importable export of customers and subscriptions. 1 8 13 14

European sovereignty

How this is scored

Who the contracting entity and the parent company are, where customer, invoice and payment data are hosted, and who the subprocessors are (hosting, payment providers, tax engines, email delivery). Independently sourced by the sovereignty pipeline; billing data is personal and financial at once, so the whole chain counts, not only the database.

0 — Non-EU vendor and contracting entity, hosting unstated, subprocessors unnamed, and no data processing agreement offered.

3 — A privacy policy and a data processing agreement exist, but hosting location is unstated or non-EU and the subprocessors are not listed.

5 — EU hosting available and an EU contracting entity or EU representative, but parts of the chain (tax engine, email, analytics, support) run through non-EU providers without a stated safeguard.

8 — EU hosting on named infrastructure, EU contracting entity, subprocessors listed with their locations, a data processing agreement published, and security certifications (ISO 27001, SOC 2) stated.

10 — Sovereign end to end and evidenced: European ownership, entity, hosting and every subprocessor, data export and deletion documented, and certifications published with their scope rather than implied.

Report an error

The Billing Engineer

The contracting entity is Sequence HQ Ltd, incorporated in England and Wales, with a data processing agreement, a subprocessor list said to be maintained and published, SCC-based transfers and SOC 2 stated; the captured pages give different figures for ISO 27001 (listed as included on the homepage and pricing pages, described as shortly to be certified in the privacy policy). Processing is described only as jurisdictions limited to the EU and US, with no named hosting infrastructure and no subprocessor locations shown. An agreement to be acquired by Intuit is signed but not stated as completed, which clouds the ownership picture. 1 2 3 4

Pricing transparency

How this is scored

Whether a buyer can compute the real annual cost from public pages alone: platform fee, percentage of billed revenue or per-invoice fees, which modules (revenue recognition, e-invoicing, tax, extra gateways) cost extra, overage above a revenue band, setup and minimum term, and the merchant-of-record fee where it applies.

0 — No public prices at all; every customer is a sales call.

3 — A starting price or a free tier exists, but how cost scales with billed revenue, invoices or modules is unclear.

5 — Tiers are public with their main inclusions and revenue bands, but at least one commonly needed piece (e-invoicing, revenue recognition, extra gateways, overage) is unpriced or "on request".

8 — Every tier priced publicly with its scaling rule (revenue percentage, per invoice, per subscriber), overage and add-ons listed, minimum term and VAT treatment stated.

10 — Complete price computability: annual cost derivable for a given billed revenue, invoice volume and module set, with every add-on, setup, support and payment or merchant-of-record fee and the cancellation and data-return terms published.

Report an error

The Billing Engineer

The Growth tier is public at $799 per month for startups with less than $1m in annual revenue, add-ons start at $499/month, and the terms state 30-day payment, nonrefundable fees, fees exclusive of all taxes and a 1% per month late charge. But both tiers above $1m in annual revenue are bespoke, assessed as a monthly platform fee from projected billed revenue, so a buyer above that line cannot compute cost from public pages. We found no public information on minimum term or payment-processing fees. 2 4
