Unite + KudTax

Connect Unite with KudTax and automate your e-commerce accounting – no manual Excel work, GoBD-compliant and ready for DATEV.

Unite, formerly Mercateo, is a B2B procurement network: buyers in large organisations order from many suppliers through one access point. For the selling merchant that means different terms from consumer business — payment terms rather than immediate payment, cash discount rather than markdown, and an invoice recipient who is not always the party receiving the goods.

What to watch for with Unite

Cash discount reduces the taxable base

When a customer takes the cash discount, the consideration drops after the fact — and with it the VAT owed. Set only the receipt against the invoice and book the difference as an expense, and the tax goes uncorrected, paid on an amount that was never collected.

Payment terms create real open items

Thirty or sixty day terms mean a substantial part of the year's turnover is still outstanding at the reporting date. Those receivables belong on the balance sheet and in the cash-flow plan — in consumer business they simply do not exist at this scale.
