What to do when a customer doesn't pay?
Assume they forgot — most late payers aren't dodging you.
Nudge on the due date. Short and friendly.
No reply in a few days? Follow up, a bit firmer.
Two weeks late → final notice is coming, say so.
A month late → send it, name the escalation date.
Before escalating, call. Emails get ignored, calls don't.
Business client? You may be owed statutory interest — mention it.
Still stuck → weigh small claims vs. writing it off.
