Full functionality — scale with your volume

All four plans include the same legally compliant core: creation, receipt, validation, VAT automation, DATEV export and the 8-year GoBD archive. What scales with your plan is volume, users, contacts and API access. Cancel monthly, no annual commitment.

Add-on options

Beyond the plans, individual capabilities can be added separately — you only pay for what you need. Add-ons are billed monthly together with your plan.

How documents are counted

A "document" is an invoice issued or received within the calendar month. Drafts, failed validations and archive retrievals don't count. Counting restarts on the first of each month; unused allowances don't carry over (no banking allowances — but your data never expires: the archive always stays complete).

Need ERP integration instead of self-service?

If your invoices come from an ERP (SAP, EDIFACT, DATEV or CSV export), we connect your system via a machine API — with its own tenant, sandbox and field mapping. This is a separate offer based on document volume and integration effort.

Which plan do I need?

Core functionality is the same everywhere — the choice depends on volume, team and integration: occasional invoicing starts free forever (Free); regular invoicing takes Basic; more contacts, more users, the invoice mailbox or the REST API call for Pro; for the highest volume, unlimited users and multiple locations there's Business. Switch anytime, with no data migration.

Archiving costs — fair, based on volume

Your documents are retained in a GoBD-compliant, audit-proof manner. Archiving costs depend on the total number of documents stored in your account and are billed monthly — free up to 100 documents. This way a Kleinunternehmer pays a fair, small amount, while larger archives scale predictably. Pure retention is thus decoupled from the plan and identical across all plans.

Honest about the paid-plan launch

The free plan includes the full legally compliant core (creation, receipt, validation, VAT automation, DATEV export, archive) and is permanent. Activation of paid plans via Stripe happens at market launch; until then you use Free with no payment method required. The prices shown are indicative — the final, binding price list will be published before activation. We disclose this openly rather than simulating a payment flow.

Frequently asked questions

Do I need a credit card for Free?

No — Free runs permanently without a payment method.

What happens if I exceed my allowance?

Issuance stops honestly with a notice (without consuming an invoice number); overage is only billed on a paid plan.

Do inbound documents count?

Yes — documents = invoices issued + received within the month.

Can I switch plans anytime?

Upgrade/downgrade monthly; you can downgrade to Free at any time.

Are there fixed-term contracts?

No, cancel monthly.

Is there a discount for annual payment?

Not currently needed: our monthly prices already match the annual-discount level of typical providers — without a 12-month commitment.

Are contacts or partners limited?

The number of stored contacts/customers depends on the plan: Free 3, Basic 20, unlimited from Pro. Items are unlimited on every plan.

How many users are included?

Free 1, Basic 2, Pro 5, Business unlimited. Additional users can be added as an add-on.

From which plan is the REST API available?

The self-service REST API and webhooks are included from Pro (Pro 10, Business 60 calls/minute). For bulk ERP integration, a separate tenant/machine API is available on request.

Where is my data stored?

Frankfurt am Main, GDPR-compliant, DPA included — and the archive remains intact until the end of the retention period even after cancellation.

How do I pay?

Paid plans via Stripe (card/SEPA) — activated at the market launch of paid plans.

Are there discounts for tax-advisory clients?

Get in touch — for tax advisors with multiple clients, we'll find a solution together.
