# Validate customer balances (AR509900)

Last modified February 19, 2026

> In this window, you can validate customer balances, starting with the selected financial period.


This topic provides information about the elements in this window in Visma Net, such as fields, field values, buttons, and check boxes.

Validation entails recalculating the balances based on the history records (released customer ledger documents) and matching them to the customer balances stored in the database.

The system also uses the open sales orders to validate whether the customer balances exceed the credit limits specified for these customers.

> [!NOTE]
> We recommend that you validate the customer balances after you change the credit validation rules.

> [!NOTE]
> Also, you may run this process if there is any discrepancy between the customer balance and the total amount of all the released customer documents. Use the [Customer details (AR402000)](https://docs.vismasoftware.no/visma-net-erp/help/customer-ledger/customer-ledger-windows/customer-details-ar402000/index.md) window to view if there is any discrepancy; use the [Customer history (AR652000)](https://docs.vismasoftware.no/visma-net-erp/help/customer-ledger/customer-ledger-reports/customer-history-ar652000/index.md) report for details on the customer account history.

In the top part, you select a financial period (and, optionally, a customer class), and
you can view the list of customers in the table.
To validate the balances of all
customers in the list, click **Process all**.
To validate the
balances of only particular customers, select the check boxes next to those
customers and click **Process**.
