Pricing and billing

Rechnungskit charges for the documents you actually create, with a small base fee and falling tiered prices. There is no permanent free plan, because Rechnungskit is a compliance product.

This page answers what you pay each month, what counts as a document, how the direct debit works and what happens to your data when you cancel.

The pricing model

You pay for two things: a base fee of €9.00 per month and a price per document. There are no add-on modules; every account includes all features. All prices are net, plus statutory VAT.

The price per document falls with volume. These are marginal prices per document in the month: each document costs the price of the tier it falls into.

An example with 250 documents in a month: the first 100 cost €0.15 each, €15.00 in total. The other 150 cost €0.11 each, €16.50 in total. With the base fee that comes to €40.50 net. Under /pricing you see your current month and a calculator.

Access for your tax advisor costs the tax advisor nothing.

No free quota, free testing

There is no free quota anymore: billing starts with the first real document after going live. Free testing runs in sandbox mode (real connections, test data only) and costs nothing. Test documents from test mode never cost anything and don't count.

Founder offer and partner code

The founder offer "6 months without base fee" was a limited offer ONLY for users who were on the waitlist during the closed beta (July to early September 2026). These accounts keep the benefit they were promised.

Since open registration (September 3, 2026) the offer no longer exists: for new accounts, the price list applies from the first billed month. If someone asks about the "6 months free", explain exactly that and don't promise the founder offer to anyone who signs up now.

For new accounts, six billed months without base fee are only available with the partner code of a Rechnungskit partner (agency, service provider, tax advisor, publisher or creator). You enter the code at sign-up, in onboarding or under /pricing, until the first billing period is closed. Documents cost the normal price during that time. There is no public discount or voucher code. Details in Partner program and partner code.

What counts as a document

A document is every created, GoBD-archived document with its own invoice number (GoBD are the German tax authority's rules for electronic bookkeeping). Each of these documents counts separately:

This matters for upsells: if a follow-up invoice is created after the first invoice, that is two documents (the original invoice and the follow-up invoice), and Rechnungskit charges you for each of them. That holds even though it is one order and the buyer paid twice.

Always included

Every account includes all features: ZUGFeRD/EN 16931, GoBD archive for 8 years, DATEV export (SKR03/SKR04), tax advisor and auditor access with self-service download, payout reconciliation for Stripe, Mollie, PayPal, Shopify Payments and Unzer, and test mode.

Payment

Platform fees are collected by SEPA direct debit. You set up the SEPA mandate yourself under /plan (enter your IBAN, confirm consent). The mandate reference is shown right away and appears on every invoice.

• Monthly invoice: at the start of each month you get the invoice for the previous month by email, with a ZUGFeRD PDF. This email is also the pre-notification of the direct debit: it states the amount and the earliest collection date.
• Collection: the direct debit goes to the payment service provider the same day, and your account is debited on the next bank business day at the earliest.
• Itemization: the base fee as its own line (with a visible 100 % discount while a promised founder benefit or a partner benefit from a partner code is running) and the documents per price tier as separate lines with quantity and tier price.
• Without a SEPA mandate: the invoice is a normal invoice paid by bank transfer, due within 14 days.
• Bounced debit: if a direct debit bounces, the terms and conditions provide for a flat fee of €10.00, and the collection is retried after 7 days. For the flat fee you get a debit note as a PDF (it is damages, so it carries no VAT and is separate from the monthly invoice).
• Shopify App Store: if your account came to Rechnungskit through the Shopify App Store, payment runs entirely through Shopify billing instead (app subscription plus usage-based fees on your Shopify bill). Rechnungskit then sends you no invoice of its own and collects no direct debit.

Cancellation and data export

You can cancel monthly. After cancellation you have 90 days for the free, complete GoBD export of your archive; after that, the data is deleted.

The export contains the original ZUGFeRD XML files plus all DATEV exports. For an e-invoice, the structured XML part is the authoritative part, and keeping it is enough as long as the PDF holds no additional tax-relevant information (GoBD of July 14, 2025, para. 76 and 131).

If you like, you can add PDF copies of every invoice; they are only a reading aid and can make the export take much longer. The export runs in the background, and you get an email with the download link as soon as it is ready.

The legal retention period of eight years (§ 14b UStG, § 147 AO) stays with you, which is why the export is complete and machine-readable.
