Animation: Hans explains one case of May 2026 in four steps. Read: invoice 506-2605-1192 from Google Ireland Ltd. for €320.00, reverse charge. Connect: the €320.00 direct debit of 18.05.2026 carries the invoice number. Propose: 4600 Marketing and ads €320.00 and 1577 Input VAT § 13b €60.80, against 1787 Output VAT § 13b €60.80 and 70004 Google Ireland Ltd. €320.00. Sort: no review reason, so the case goes to Confirm together.

Hans identifies the supplier, amount and tax treatment on the invoice.

Prepared for professional review

Hans prepares the books. Your firm reviews them.

Start with connected entries, payments and evidence, with unresolved questions made explicit. Your firm sets the standards, reviews the work and gives final approval.

Hans handles the preparation

  • Reads invoices, contracts and payout statements
  • Connects entries, payments and supporting evidence
  • Prepares account assignments and tax treatment
  • Flags questions and applies your review rules
  • Records processing steps and changes

Your firm keeps control

  • Sets review rules for the firm and each client
  • Reviews exceptions with the relevant evidence
  • Adjusts entries and confirms suitable cases together
  • Approves the books and closes the month
  • Retains tax advice and filing responsibility

Review by your standards

Direct attention to the cases that need it.

A large amount, a missing document or an unexplained difference: your rules determine what needs individual review. Set a firm standard and refine it by industry or client; required reviews remain protected.

Animation: three cases of May 2026 pass the five rule levels. SpreeFuel at €5,478.25 has the high-value reason; the firm standard reviews from €5,000.00, so it goes to Review individually. The charging session without a receipt has no input VAT; at €58.70 it stays below the firm standard's €250.00 and goes to Confirm together. The tyre quote is a document without a booking; the required level keeps it in Review individually.

Review individually

Most specific policy wins, then legal floors keep the result from weakening.

Animation: the activity of one case, a €267.92 payment to DispatchOps Inc. for a USD invoice. Hans matches the payment and notes a €0.66 difference. The client requests your review, so Hans places the case in Review individually. Your firm matches the payment; Hans books the exchange difference to 2150 and the case joins Confirm together. Your firm confirms the list and closes May 2026.

Questions about AI bookkeeping

What does AI bookkeeping add beyond OCR?

OCR extracts information from a document. DeinHans works across invoices, contracts, bank transactions and payout statements to prepare the monthly books. It connects entries with payments and evidence, identifies unresolved questions and organises the work for your firm’s review.

Can we inspect or change what Hans prepares?

Yes. You can open a case, inspect its documents, payment allocation and proposed entry, and make corrections. Your firm confirms or approves the work. Month close posts approved entries that remain unposted and locks the period; approval, posting and closing stay visible.

What needs individual review?

Your rules determine which review reasons and amounts require individual attention, for example a large transaction or missing VAT evidence. Rules can apply across the firm, to an industry or to one client. A requested professional review or a document without a booking always requires individual review. Other eligible proposals can be confirmed together.

Can we keep DATEV and our existing workflow?

Yes. Your firm can continue using DATEV for its established work, such as payroll. DeinHans prepares monthly bookkeeping and exports the reviewed books in DATEV format with SKR03 accounts, tax keys and document references. We align the setup with you; the export is not live two-way synchronisation.

What remains with the tax firm?

Your firm sets the review standards, resolves professional questions and gives final approval. Tax advice, filings and annual accounts remain with you. Clients can supply records and clarify business matters without being asked to make tax decisions.

How can we assess this on our own clients?

Start with a free 30-minute demo using sample records. If the workflow fits, we help you set up one suitable client for a free 30-day trial covering one bookkeeping month. You assess the records, review quality and effort with your team. No credit card or automatic paid subscription is required.
