The provider states real-time validation against German tax rules and internal policies. This is a provider capability claim, not independent assurance of tax compliance. Its page also announces that Circula is part of Personio.
No count stated by provider. DATEV Premium Partner and DATEV marketplace API partner; “official successor solution for DATEV Reisekosten classic”. No SAP, NetSuite, Xero or Lexware named
Limitations
“Continuous compliance audits” labelled “coming soon”; exported expenses, mileages and per diems cannot be recalled or edited afterwards (corrections outside Circula); DATEV format cannot carry receipts into ReWe; AI “Built for German legislation”
Only accuracy figure is provider-stated evidence verbatim: “92% less manual input” (measurement not described)
Fit and decision conditions
Prerequisites
Minimum 10 licenses; GoBD-compliant 10-year archiving requires a certified DMS (e.g. DATEV Unternehmen online) or Circula's optional archiving service; DATEV data services ordered for clients
“Prices stated per month, billed annually.” “Circula always contains a minimum of 10 licenses.” Add-ons (DMS, CustomerCare Plus, DailyTrips, CO₂ Reporting, Multi-Entity Setup) unpriced
Published price
From 15€ per license/month (Employee & Travel Expenses); from 99€/month (Credit Cards platform); from 149€/month (Accounts Payable, incl. 100 invoices); from 1€ per license (Benefits)
The provider’s own sources say different things here. Starting prices. The pricing page labels Accounts Payable “coming soon” while a product page describes it; confirm availability and invoice overage charges.
AI page says “hosted in Europe” plus badge “Hergestellt und gehostet in Deutschland”; consistent with Germany. Privacy policy names US recipients for analytics/error tracking (see subprocessors and models)
Certificates and audit reports
ISO/IEC 27001:2022 “for Circula GmbH in Berlin for cloud operations and security management”; GoBD software audit “according to IDW PS 880” by Eger, Färber & Kollegen Wirtschaftsprüfungs und Beratungs GmbH (attestation)
Provider-stated ISO 27001; confirm issuer and dates. IDW PS 880 is an auditor attestation. GoBD and GDPR are rules; DATEV Premium Partner is partner status.
Additional data conditions
Subprocessors and underlying models
Privacy policy (app): unnamed Frankfurt/Main data-centre provider, Omni Analytics Inc., Metabase Inc., Stripe Payments Europe, Chargebee Inc., Functional Software Inc. (Sentry), Intercom, HubSpot, Pliant GmbH/Pliant Oy, PostHog Inc.; hosting AWS Germany. No LLM provider named
Privacy policy concerns Circula as controller. An OpenAI name in an example receipt does not establish model integration.
Retention and deletion
Account data “stored as long as your account exists” (legal retention may apply); error tracking deleted after 90 days; session recordings 3 months; DMS article: “archiving must take place digitally for 10 years” (via certified DMS)
Expense-data deletion at contract end needs separate confirmation.
Export
CSV, PDF (per employee/trip), ZIP of receipts, DATEV format, DATEV XML (UO), SEPA XML, direct transfer to DATEV Unternehmen online; payroll exports for DATEV LODAS / Lohn und Gehalt
Partial – AI “routes low-risk claims automatically”; “Higher-risk or non-standard expenses are flagged for review.” Help: supervisor approves, accountant controls; “A trip can only be prepared for export once it has been approved as a whole.”
The provider’s own sources say different things here. The AI page describes automatic routing of low-risk claims; help documentation describes manual approval before export. Confirm which workflow applies.
GoBD: “certified as compliant software by Eger, Färber & Kollegen … according to IDW PS 880”; e-invoices: “XRechnung” and “ZUGFeRD” “können im Zusammenhang mit Ausgaben in Circula verarbeitet werden”; real-time checks “against the UStG, UStDV”
Provider-stated support; IDW PS 880 is an attestation. No Peppol or SAF-T mentioned
Questions for the provider
Ask the provider whether your data is used to train models and which consent controls apply.
Ask the provider for the price, billing unit and required commitment for your scope.
Ask the provider which retention and deletion terms apply, including when the contract ends.
Cost per accepted outcome
Editable hypothetical example · not provider pricing or measured performance. Use this monthly worksheet to test your own quote and quality assumptions.
/ accepted outcome
accepted outcomes / month
5,000 tasks × 80% = 4,000 accepted outcomes per month. Higher entered costs raise unit cost; more accepted outcomes spread the same cost over more results.
Formula: entered monthly costs ÷ (monthly tasks × acceptance % ÷ 100). The numerator includes only the costs you enter. Add applicable licence, usage, integration, human review and rework costs yourself; this is not automatically a fully loaded estimate or a vendor billing model. Capacity released is not realized financial value.
Inputs stay in this browser tab’s session, including reload and language changes. They are not added to the page URL. Continuing prepares an unsent enquiry draft.
