Import, check, approve, export: this is how a month runs in AppKonto. The excerpts below show the interface with sample data of Beispiel GmbH.
Connect App Store Connect, Google Play and Stripe, or upload the reports as files. Every original file is archived unchanged with SHA-256.
AppKonto assigns every line to an Apple or Google entity or a tax case, converts to euro and collects everything that is still missing in one list.
Approval is per channel. Your tax advisor can review and approve too. The month takes the status of the channel that is furthest behind.
One download per month: separate DATEV batches for App Store, Google Play, Stripe revenue and Stripe payments, plus all documents.
AppKonto reads the reports each channel already provides and applies the German tax case to every line. Details are on the channel pages.
| Channel | What AppKonto reads | What it produces |
|---|---|---|
| App Store | Financial Reports (ZZ, Z1, Payments CSV) by upload or via the App Store Connect API | Invoice to Apple Distribution International (Kz 21, EC Sales List), self-billing documents for Apple entities outside the EU (Kz 45), bookings by the net method |
| Google Play | Earnings reports (ZIP and CSV) from the Cloud Storage bucket of your Play account, or by upload | Document to Google Commerce Ltd (Kz 21, EC Sales List), bookings per country, reconciliation with the payout |
| Stripe | Balance transactions, invoices, credit notes, refunds, disputes and payouts through a key that can only read | Tax case per sale (domestic, OSS, reverse charge, third country), two DATEV batches, archived invoice PDFs |
Apple and Google do not issue you a German invoice for your revenue. You supply the platform, not the other way round. So you issue Apple Distribution International and Google Commerce Ltd in Ireland an invoice without VAT that refers to the reverse charge.
Apple pays out even without your invoice. You still have to issue and keep it, as a rule by the 15th of the following month. AppKonto creates the document from the report, numbers it without gaps and locks it after approval. For Apple entities outside the EU it creates a self-billing document.

Sample data
Reverse charge, tax due from the recipient
You or your firm decide which account and cost centre a booking goes to. Before saving, the tester shows which bookings change.
RuleIf the Stripe metadata app reads wetterfrosch or the App Store SKU is wetterfrosch.pro, then cost centre 100.
Your firm imports DATEV files like any other booking batch. sevDesk and Lexware Office receive approved bookings directly.
There is no DATEV online interface yet.
AppKonto includes an MCP server. An agent with an access token reads months and explains bookings, a person has to approve.
Your clients with app revenue send you DATEV files you can import at first try. For every line you see the source, rule, tax rate and exchange rate. Disputed treatments are profile options with a default value that you approve once.

8336 is an automatic account, so BU stays empty. DATEV derives Kz 21 from the account.
You pay per company and month. The plan follows the monthly revenue: the App Store and Google Play payouts after their commission plus the Stripe net sales. Try for 14 days, a payment method is required. Cancel monthly in the customer portal.
You book as revenue the amount Apple or Google pays out to you, that is, after the commission. The commission is not a separate supply and is not booked as a purchase with reverse charge. AppKonto uses this method by default, with the automatic accounts 8336 (SKR03) and 4336 (SKR04). A gross presentation is an option for the firm.
Your service to Apple Distribution International in Ireland is a service to a business in the EU. German VAT law requires an invoice for it, as a rule by the 15th of the following month. Apple pays even without that invoice. It carries no VAT but refers to the reverse charge.
There you are the seller. AppKonto determines the tax case for every Stripe sale: domestic, EU consumer, OSS, reverse charge, third country, Managed Payments or small business. The threshold for EU sales to consumers is €10,000 per year. AppKonto tracks it and switches to the OSS scheme from then on.
Yes. The net method also suits small businesses, and Stripe sales get the small-business tax case. Whether § 19 UStG applies to you is for you and your tax advisor to decide and enter in the company profile.
For the App Store the monthly Financial Report (ZZ or Z1) and the Payments CSV, for Google Play the monthly earnings report, for Stripe a key with read access. Apple and Google can be connected by API or uploaded as files.
Yes. You invite your firm to the company as an advisor. It reviews, approves and exports the DATEV files without needing a new portal. Firms can also maintain booking rules.
Original reports are stored byte-identical with SHA-256. Approved documents and exports are immutable, corrections go through reversal, and an audit log records every change. AppKonto is designed around GoBD; there is no certificate for it.
The application runs in an EU region. This website itself sets no tracking cookies and loads no analytics.
