There's a persistent myth that asking for money is "bad for business." The data says the opposite: businesses that follow up early and consistently get paid faster and lose fewer clients than those that wait or give up.

Why Day 7 is Critical

Our internal data (across thousands of DueKeep users) shows that invoices followed up on within 7 days of the due date are 3x more likely to be paid within 30 days than those where the first follow-up happens at day 14+. The longer you wait, the less likely payment becomes.

The Psychology of "Friendly but Firm"

The worst thing you can do is send an apologetic email: "Sorry to bother you, but I just wanted to check in, no pressure..." That signals that you're not serious about getting paid. Instead:

  • State the facts: invoice number, amount, due date.
  • Ask a direct question: "Is there anything preventing payment?"
  • Offer help: "Happy to resend the invoice if needed."
  • Never apologize for asking.

What About "Net 30"?

If your payment terms say "Net 30," you might think you have to wait 30 days to follow up. You don't. "Net 30" means payment is due in 30 days — not that you can't ask questions before then. Following up on day 3 is entirely within your rights and is standard B2B practice.

Automate This

DueKeep sends the right email at the right time automatically. Set it up once and never chase payment manually again.
