- 8336 is an automatic account, so BU stays empty. DATEV derives Kz 21 from the account.
- Apple entities outside the EU: account 8338, not taxable, Kz 45.
- Kz 81 comes from domestic Stripe sales. The Stripe batch books them to 8449.
What app clients cost today
Apple and Google pay out without supplying booking entries. The assignment stays with you or your client.
| Problem in practice | Result with AppKonto |
|---|---|
| Apple and Google pay out net, the tax has to be reconstructed | Net method as default, return fields Kz 21, Kz 45 and Kz 81 per channel, plus the OSS return |
| Revenue from over 100 countries with different treatment | Assignment per Apple or Google entity and per tax case, country breakdown in the document |
| Commissions, taxes and payouts sit in separate reports | One month across App Store, Google Play and Stripe, reconciled against the bank payment |
| Monthly settlement ties up bookkeeping work | DATEV batches that do not get rejected on import |
Every number leads back to its source
For every booking AppKonto shows the chain from report line through settlement and booking to the document and export line. You see accounts with names, the rule applied with its version, the source file with SHA-256, plus rate and rate source.
- Original reports stay stored byte-identical
- Approved documents and exports are immutable, corrections go through reversal
- Every change is in the audit log with person and time
- Disputed treatment is a profile option with a default, not hard-wired
How your firm works with AppKonto
Client invites you
The client gives your firm access as an advisor. No new portal is needed.
Approve the profile once
You confirm the default treatments, for example net method, rate source and EC Sales List scope, and enter adviser and client numbers.
Review and approve the month
The checklist names open items per channel. You spot-check down to the source line and approve.
Import into DATEV
You import the EXTF 700 files by batch processing. A document package and debtor master data can be added on request.
Maintain rules the same way for all clients
Firms can maintain booking rules: account, cost centre, booking text or hold, by app, channel, product or Stripe metadata. The rule tester shows before saving which bookings change. No rule changes tax treatment, only the profile does.
AppKonto provides booking proposals, not tax advice. Responsibility for the treatment stays with you.

Questions from firms
Which DATEV format does AppKonto produce?
Booking batches in DATEV format EXTF, version 700, format version 13, with 125 columns. Debtor and creditor master data come with it, and on request a document package with PDFs. Before export the file is validated against DATEV rules, such as the length of Belegfeld 1 and the account length.
Is there a DATEV online connection?
Not yet. Your firm imports the file. A direct interface requires DATEV onboarding and is not part of the current offer.
How are firms billed?
Per client, that is per company, by monthly revenue. Details are on the pricing page.
How does AppKonto handle the EC Sales List scope?
By default all revenue via Apple Distribution International and Google Commerce Ltd belongs in the EC Sales List. You can change this in the client's profile.
