AccountOne carries out an independent, detailed VAT assessment for each Shopware order. In this way, we ensure that the revenue postings arrive correctly in the accounting department. We transfer the revenue using the individual booking procedure. In other words, each order receives its own booking in the accounting department.

The order data also includes the payment type and other payment information. This information is used to assign the payment to the invoice, provided the payment system is also connected to AccountOne.

Shopware orders are posted using the individual posting method - each order receives at least one posting line. If there are different tax situations, the posting may be split in order to display mixed tax rates.

AccountOne provides a DATEV-compatible CSV record for the orders from Shopware 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.

So you don't have to create an ASCII import, but you can use the board means of DATEV to import the data. This prevents errors during the import.
