# Payment Disputes and Adjustments In some cases, a payment may not match the amount due on an invoice, either because of errors or disputes over the product or service. ERP systems streamline the process of managing these situations by allowing adjustments to invoices and payment records. **Managing Payment Discrepancies:** * **Disputes Over Products:** Flag invoices where the customer has raised an issue, and put payments on hold until the dispute is resolved. * **Adjusting Invoices:** Update invoices to reflect agreed changes, such as price reductions or discounts for late deliveries. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
