When you export a pay request, you can include an item's certificate documents so the certification package travels with the invoice. The certificate documents are added to the end of the invoice document.

You set this in the pay request's export settings when you export it.

The certificate documents are added to the end of the invoice document.

Note: Only PDF certificates are added to the pay request document. Spreadsheet files (XLS, XLSX, ODS, and CSV) are stored with the certification but are not added to the invoice document.

For a large set of documents, Oversite prepares the export in the background and emails you a link to download the finished document when it is ready.
