AccountOne performs an independent detailed VAT assessment for each Amazon order. This ensures that the revenue postings 100%ig arrive correctly in accounting. We transfer the revenues using the individual posting procedure. This means that each order also receives its own posting in accounting.

In addition, AccountOne reads the disbursement reports (settelments) from Amazon and also creates postings for accounting from them. With these, a payment movement is assigned to each individual revenue posting in accounting. Furthermore, the fees from Amazon are also posted in this course.

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

The Amazon disbursement reports are treated in accounting like a fictitious bank account. Only in this way can the tax advisor also be 100%ig sure that all movements have been posted without exception.

AccountOne provides a DATEV-compatible CSV record for the orders and payments from Amazon 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.

This means that no ASCII import has to be created manually in the law firm; instead, the DATEV board tools can be used to read in the data. This prevents errors during import and guarantees a smooth process.
