Yes, but you don’t pre-build these rules. Instead, the system creates a link between the category with the merchant when saving the claim, both for receipts and bank transactions with your Expenses category. See [AI in Expenses](/payroll/docs/ai-in-expenses). #### Why is a category not available when a user creates an expense claim? If a category is not available, ensure the **tag** fields on the category record are empty. See [Creating and editing categories](/payroll/docs/creating-and-editing-expense-categories). ![](https://cdn.document360.io/fc2cda72-4645-4b36-96bf-60439ec11f11/Images/Documentation/image(534).png) ![](https://cdn.document360.io/fc2cda72-4645-4b36-96bf-60439ec11f11/Images/Documentation/image-LVCRRC7D.png)
