The data is uploaded to AccountOne on a monthly basis via Smart Import. We have provided detailed instructions for this in the helpdesk.

Once the data from OTTO Market has been imported into AccountOne for accounting with DATEV, the system begins to assign the individual payment transactions to the corresponding invoices from the online store or the invoice (for SaaS). The assignment is made using special transaction identifiers that are already contained in the order data from the online store or the data from the invoice.

This assignment also makes it possible to address the correct debtor. It is therefore not necessary to intervene manually in DATEV.

OTTO Market orders are posted individually - each order receives at least one posting line. If there are different tax situations, the posting may be split to show mixed tax rates.

AccountOne provides a DATEV-compatible CSV record for the orders from OTTO every month. This is regularly checked with the DATEV checking tools and guarantees a smooth import to DATEV. In addition, our export to DATEV is batch processable.

You therefore do not have to create an ASCII import, but can use the DATEV board tools to read in the data. This prevents errors during import.
