Invoicing & accounting

lexoffice + KudTax

Export booking-ready e-commerce data directly into lexoffice – seamlessly transfer journal entries, tax keys, contra accounts and digital document attachments.

For many smaller sellers lexoffice is the leading accounting system, and it reaches its limits precisely when document volume from marketplaces and payment providers climbs. Hundreds of individual transactions a month can no longer sensibly be entered one at a time. KudTax condenses them into checkable entries first and hands over incoming and outgoing invoices with their VAT rates.

What to watch for with lexoffice

Document volume outgrows individual entry

Past a few hundred transactions a month, entering each one becomes a full-time job. Summary entries are the right answer — but only while the individual transactions behind them stay intact and checkable. A total with no detail is not a document.

Payment provider fees often go missing entirely

Capture only the incoming payment and the fee withheld is missing as expense while revenue is understated. The error is small per transaction and material over a year.
