Stop retyping paperwork
Invoices read, line by line
Drop in a PDF or photo of an invoice or receipt. Muin reads what it says and holds it for your approval.
W-9s and certificates collected for you
Type a vendor's name and email and Muin sends a request link. The vendor uploads on their own page, with no Muin account.
Checked, not just read
A W-9 needs a valid taxpayer ID and a signature. A certificate is checked for each limit you require, additional insured, waiver of subrogation and its expiry date.
Problems stop at the door
A document that fails a check shows the reason and cannot be approved. A taxpayer ID only ever shows its last four digits.
Duplicates counted
The home screen counts invoices that may already be on file, so a second copy of the same bill is easy to catch.
Into your books or a spreadsheet
Export what every document says to a spreadsheet. With QuickBooks connected, approved invoices go there as bills.
