# Accounting Integration API

**The objective of** accounting integration is to *automate the creation and flow of transactions between the Dataloy VMS and an accounting system*. The advantage is, for example, reduced risk of errors as several transactions handled by the Dataloy VMS system generates transactions to be entered in a client accounting system. An integration also allows for synchronizing the basic data entities (or [*Master Data*](/api-release-8.25/dataloy-rest-api/master-data-objects.md)*, i.e. several of the same being stored and maintained in both systems*) between systems. Some Master Data, for example, Business Partners, must be synchronized for the integration to work.

## **Accounting Integration Transactions**

#### **Transactions from Dataloy VMS to Accounting:**

* Sales and purchase invoices are transferred whenever an invoice/invoices is/are posted in the VMS.
* Bunker transactions are transferred whenever a bunker transaction is posted in the VMS.
* Vessel/Voyage information is sometimes required by Accounting before invoices and/or bunker transactions are transferred. A scheduled task for transferring this type of information to Accounting can be set up (contact Dataloy for more information).
* Accruals will be transferred by users when performing period-end-closing (*more information:* [*Accruals*](https://docs.dataloy.com/voyage-management-system/step-by-step-guides/finance/accruals) *page and the* [*Period-End-Closing*](https://docs.dataloy.com/voyage-management-system/step-by-step-guides/finance/accruals/period-end-closing) *process*).

#### **Transactions from Accounting to Dataloy VMS:**

* Receipts and payments being transferred from Accounting to Dataloy VMS. The transaction to collect and payments and send to the VMS is either triggered by Accounting or by a scheduled task (set up by Dataloy Systems).
* Exchange rates will be transferred from Accounting to Dataloy VMS. This transaction is either triggered by Accounting or by a scheduled task (set up by Dataloy Systems) to collect and retrieve the rates.
* Actuals is part of the [Period-End-Closing process](https://docs.dataloy.com/voyage-management-system/step-by-step-guides/finance/accruals/period-end-closing) and is usually transferred from Accounting to Dataloy VMS.
