Anyone here ever paid the same invoice twice? How'd you catch it, or not?
A bookkeeper I was talking to told me about the time her company paid the same invoice twice. The vendor had sent it once by email and once by mail, both got entered, both got paid, and nobody noticed until the vendor flagged the overpayment weeks later. A few thousand dollars out the door, then the awkward clawback.
What stuck with me is there was no real safety net. QBO doesn't wave a flag that says "hey, you might've already paid this one." It just relies on a human catching it, and when invoices come in from five different places, humans miss it.
Has this happened to anyone here? How do you catch duplicates before they go out some system, a second set of eyes, or do you mostly find out after the money's already gone?
