How do I add a document to an expense

I need to add the original receipt to a payment made as it is for a grant and they need all original receipts to be attached to payments made.

If your grantor requires original receipts, you have no choice but to print out the invoice, attach the copies, and mail or hand deliver.

If the grantor will accept copies or scans, print or save the invoice as a PDF file. How you do that depends on your operating system. You might need to download a free PDF generator, or the capability might be built in. You can then add scanned pages to the PDF document with appropriate PDF software. The resulting file can be emailed or printed and mailed.

Manager does not yet allow direct storage and manipulation of auxiliary documents such as receipts, but eventually will.

Many thanks for that I will just PDF them and send with reports.

Many thanks again
