Fully automated data retrieval

Our API interface retrieves the data from Plentymarkets several times a day and makes it available as accounting data on a monthly basis.

Reconciliation with Payments

The revenue transactions are automatically assigned to the payments (provided the payment system is also connected to AccountOne). The fee items and payouts are also posted fully automatically.

100% DATEV compatible export

Our exports are fully batch processable. This means that no import profiles have to be created in the accounting department, but can be imported directly using the DATEV board tools.

Minimally invasive integration

AccountOne integrates into the existing API and tech stack without interfering with other systems.

The data can be retrieved fully automatically via API. We have provided detailed instructions for this in the helpdesk.

Each order is independently evaluated in detail for VAT purposes. In this way, we ensure that the revenue postings 100%ig arrive correctly in accounting. The transfer of the revenues takes place with us in the individual posting procedure. This means that each order also receives its own posting in accounting.

AccountOne also reads payments and fees from various payment service providers and uses them to create postings for accounting. In addition, a payment transaction is assigned to each individual revenue posting in accounting.

Shopify 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 Plentymarkets 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.

In some cases, it can be advantageous for accounting if the data from marketplaces is obtained directly via the marketplace APIs. This is always the case if the marketplace or store has an integral payment system. This is the case with Shopify or Amazon, for example. In these cases, individual order origins can be excluded from Plenty.
