Your late fee policy line

Payments received after the due date incur a late fee of 1.5% of the unpaid invoice amount for each month, or part of a month, it remains unpaid.

How the fee is worked out

For a percentage fee, the math is the unpaid amount times the monthly rate times the months late. Each 30 days, or part of 30 days, past the grace period counts as a month. The fee is charged on the original amount only, never on earlier fees. A flat fee is charged once.

Example: a $2,400 invoice at 1.5% a month, paid 45 days late with no grace period, counts as two months. The fee is $72 and the new total is $2,472.

What rate is normal

Many small businesses charge 1% to 1.5% a month, or a flat fee like $25. That monthly rate works out to 12% to 18% a year. Limits depend on where you and your client are, so check the rules before you set a rate.

The rule that makes a late fee work

A late fee only holds up if the client agreed to it before the work started. Put the policy line from the calculator on your quote, your contract and every invoice. A fee that first appears on a past-due notice is hard to collect and reads as spite. The invoice late fee policy guide has a full policy to copy and the email to send when you add a fee.
