# TAP Studio - Define Invoices Naming Convention This use case presents how to define a naming convention for your invoices. In this example, the robot will take 3 invoices that were exported from the invoice solution with file name "INV-" + Index (e.g. INV-000001) and rename them following the naming convention: \[Invoice Number]\_\[Customer Name]\_\[Invoice Year]\[Invoice Month]. In order to reduce the automation running time, we will take the invoice data from the excel file InvoiceReports, as we exported it already during the [previous use case](https://docs.tailent.com/hc/en-us/articles/360013972318).\ If you haven't had the chance to watch our [previous use case](https://docs.tailent.com/hc/en-us/articles/360013972318) about how to extract invoice data using OCR, we recommend you to do so.
