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

The Tax Adviser

Weighted verdict

Advises software and subscription businesses and sees what their billing tools get wrong at the year-end audit. Wants sequential numbering and credit notes instead of edited invoices, XRechnung and ZUGFeRD now that the B2B e-invoice is mandatory, VAT IDs checked before reverse charge is applied, and a merchant of record that says in writing which tax it owes.

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 Tax Adviser

The commercial model lives in the product: usage, seats, hybrid, minimums and credits with monthly burndown, rollover and overages, all with proration and amendments handled, quotes turned into contracts through the CPQ, and real-time metering priced against each contract. The branded customer portal shows invoice history, real-time usage and credit transactions, and can be embedded via the API. We found no public information on customers changing or cancelling their own subscription in the portal, on grandfathering of price changes, or on entitlements exposed to the selling application. 1 5 6 7 14

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 Tax Adviser

Credit-note discipline is the strongest part: notes are created against issued invoices or from scratch, line items adjust until finalisation, notes are voided rather than edited away, they carry the related invoice number, date and amount, and maintain an audit trail — exactly how corrections should work. Tax IDs and reverse-charge VAT numbers are placed on the invoice. We found no public information on sequential invoice numbering, a documented invoice archive, or structured e-invoices to EN 16931 such as XRechnung, ZUGFeRD/Factur-X or Peppol. 5 7 8 10

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 Tax Adviser

Tax is applied to each invoice line from the product's tax category, the customer's region and their tax status, with rate tables per country and per US state, and reverse-charge invoices carry the customer's VAT number and no tax rate — sound mechanics. What I want before signing off a reverse charge is validation of that VAT number, and we found no public information on VIES checks, OSS reporting data, or stored evidence of customer location; the rate tables are also maintained by the seller rather than the vendor. US sales tax is covered through named engines including Avalara and Anrok, with Numeral handling automated return filing. 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 Tax Adviser

Dunning is well built: reminder sequences on a workflows canvas timed relative to the due date, branching by customer and invoice amount, automatic stop when an invoice is paid, voided or written off, optional human approval in Watchtower, and a full audit trail of every reminder. Collection runs across various payment processors — Stripe and GoCardless are named — plus bank-transfer destinations spanning IBAN, UK transfer, US ACH, US wire and Swedish Bankgiro, and a migration service off Chargebee, Maxio, Zuora and Stripe exists. We found no public information on SEPA direct-debit mandates, automatic retries of failed payments, card updaters, recovery reported per dunning step, or a handover to a collection agency. 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 Tax Adviser

Recognition to ASC 606 and IFRS 15 runs in a dedicated sub-ledger, the journal report reconciles to the deferred revenue and waterfall reports, journals post straight to Xero with incremental repush, and export formats cover Xero, QuickBooks, NetSuite and a generic GL, with manual adjustments tracked as Standalone under a full audit trail. Native two-way connectors reach Salesforce and HubSpot plus the data warehouses Snowflake, BigQuery and Redshift, and a REST API with signed webhooks covers customers, invoices, billing schedules, credit notes and quotes. We found no public information on MRR or churn dashboards, or on a documented complete export of customers and subscriptions that a successor system could import. 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 Tax Adviser

The contracting entity is Sequence HQ Ltd, incorporated in England and Wales under English law, with a data processing agreement published, SOC 2 Type II stated, and a maintained subprocessor list. Processing is described as limited to the EU and US with standard contract clauses as the transfer mechanism, so the chain is not purely European, and the captured pages give different figures on ISO 27001 — listed on the homepage and pricing page, while the privacy policy says certification is expected shortly. An agreement to be acquired by Intuit has been signed, and we found no public information on named hosting infrastructure or the locations of individual subprocessors. 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 Tax Adviser

Growth is public at $799 per month for startups with <$1m in annual revenue, the quote builder and revenue recognition add-ons start at $499/month, and the terms state fees are exclusive of taxes, due within 30 days, with 1% per month late interest. But Core for companies with $1-10m in annual revenue and Scale for $10m+ are both 'Bespoke pricing', and the monthly platform fee is assessed on projected billed revenue and the features required, so a buyer beyond the entry tier cannot compute the annual cost from public pages alone. 2 4
