# Bill is within installment window, and cannot change its installments. Please delete the bill in NetSuite and try to export again.

## Error message

```plaintext
Bill is within installment window, and cannot change its installments. Please delete the bill in NetSuite and try to export again.
```

## Affected ERP integlrations

- Oracle NetSuite

## Cause

This error occurs when a bill uses Oracle NetSuite's installment feature, which is typically associated with the payment terms of the vendor. When a bill has installments configured, the ERP locks certain fields during the installment window to maintain payment schedule integrity.

If an expense with installments is returned for review in Payhawk and changes are made, Payhawk cannot update the bill in Oracle NetSuite due to these restrictions.

## Solution

To resolve this issue:

1. Log in to Oracle NetSuite.
2. Locate the bill referenced in the error using the expense details or NetSuite ID.
3. Delete the bill from the ERP.
4. Return to Payhawk and re-export the expense.

> [!TIP]
> Deleting and re-exporting is necessary because Oracle NetSuite does not allow modifications to bills within the installment window.

For more details on how installments work in Oracle NetSuite, see the [Oracle NetSuite article on vendor payment installments](https://docs.oracle.com/en/cloud/saas/netsuite/ns-online-help/section_1550603013.html).
