laeuft/Account/Bookkeeping & DATEV
Bookings prepared, handed over in DATEV format.
laeuft reads every invoice and every marketplace money flow, links it to its invoice number, books it to your accounts by rule and hands the month to DATEV. Balances, VAT returns and annual accounts stay with your accountant.

Marketplaces pay in bundles, but your books need single lines.
A payout mixes dozens of orders, refunds, commissions and ad fees. Without a link to the invoice number, someone splits it by hand every month, or the accountant does and bills you for it.
How it works
Six steps from source to batch, most of them automatic.

Linked to the invoice
A fee or payout finds its invoice through the order or channel order number. The invoice number becomes document no. 1, the anchor for open items in DATEV.

Booked by rule
A rule maps source and transaction type (optionally channel, tax case, country and rate) to account, contra account, tax key and cost centre. The most specific rule wins.

Gaps go to the inbox
A new transaction type raises “booking rule missing”, a booking without an invoice raises its own task. Both close themselves once a rule or link covers them.

The batch freezes the month’s bookings in DATEV format and is never sent twice. Anything that arrives later goes into a follow-up batch.
Details
What your accountant will ask.
- Accounts are your data
- Accounts and rules live in your settings, not in code. Set them up with your accountant, e.g. on SKR03.
- Rule sets in versions
- You change rules in a draft and release it. A released version never changes; bookings always use the latest released one.
- “Don’t book” is a rule too
- Types that don’t belong in the books are excluded explicitly, so nothing disappears silently.
- Debtor by payment method
- Each document books to the personal account of its payment method, e.g. one debtor per marketplace payment service.
- No double bank bookings
- Bank accounts DATEV books from its own bank feed are never booked by laeuft; payouts run through money in transit.
- Payment advices and discounts
- A transfer paying several invoices is split per invoice; a deducted discount becomes its own booking.
- OSS
- The VAT decision of each document (tax case, country, rate) selects the rule and fills the EU fields of the booking.
- DATEV format
- Bookings batch (EXTF, category 21, format version 13), imported by your accountant’s batch processing.
- Direct to DATEV
- The direct transfer to DATEV Unternehmen online (bookings and document images, each booking linked to its document) is built and goes live once DATEV has approved it. Until then the batch is a file.
- Document images
- Documents laeuft issued go along as the file the buyer received: ZUGFeRD PDF/A-3, or XRechnung for public-sector buyers.
- Corrections never overwrite
- After handover, bookings belong to DATEV. A correction is a new, explicit booking, never a silent change.
- What stays with your accountant
- Balances, closings, VAT returns, OSS returns and annual accounts. laeuft prepares, DATEV books.
Questions
Asked often.
Does laeuft replace my accountant?+
No. laeuft replaces the manual preparation: downloading reports, splitting payouts, assigning accounts. Your accountant receives finished bookings and keeps doing closings and returns.
What happens with a transaction type laeuft doesn’t know?+
It is not guessed. It shows up as “booking rule missing” in the inbox, and the month can’t be marked reviewed until a released rule covers it.
Which marketplaces deliver their numbers automatically?+
Marketplaces with a finance API are read directly. Where a platform only offers a report, you upload it and confirm its columns once; after that the same format is read without asking.
Can I change something after the handover?+
Handed-over bookings are not touched. New source bookings for that month reopen it for a follow-up batch; corrections are new bookings.
How does the data get to DATEV today?+
As a DATEV format file your accountant imports. The direct connection to DATEV Unternehmen online is built and switches on as soon as DATEV approves it.
