The invoice number trick that stopped a 60 day delay
Back in March I had a client in Austin sit on a $2,400 invoice for two full months. Turns out their accounts payable system auto-flagged anything without a PO number, and my invoice just sat in limbo. I started adding a fake PO field with "N/A" and the job number after that, and payments started hitting in under 2 weeks. Also learned to send the invoice as a PDF named with the invoice number, not "Invoice Final v3" or whatever. Has anyone else had success with formatting tricks just to get past an automated filter?
Love that we've all basically become hackers just to get paid on time. Your fake PO number move is solid though, I've been doing the same thing for years except I put the actual job number in the PO field and write "see PO" in the notes, which seems to fool most systems into thinking there's a real reference. The PDF naming thing matters more than people realize too, I had one client's system reject anything with spaces in the filename, so now everything is INV-2024-047.pdf, no spaces, no version numbers, no nonsense. Wild that we have to outsmart software just to collect money we already earned.
