Late Fee Policy for a Small Service Business: An Example
A common late fee policy charges a flat fee (often $25–$50) or a percentage (1–1.5% per month) starting a set number of days after the due date, stated on the invoice and agreed to before the job starts. Check your state's rules on late fees and interest before setting a specific rate, since limits vary — but the bigger factor in whether a late fee actually gets paid is stating the policy up front, not the exact number you land on.
A sample policy
“Invoices are due within [14] days of completion. A late fee of [$25 flat / 1.5% per month] applies to any balance unpaid after [10] days past the due date.”
Adjust the numbers to your market, but keep the structure: a clear due date, a clear grace period, and a clear fee.
Flat fee vs. percentage
- Flat fee ($25–$50): simple, predictable, easy to explain regardless of invoice size.
- Percentage (1–1.5% per month): scales with the job — a small fee on a small invoice, a larger one on a bigger job.
Either is standard practice; pick whichever is easier for you to communicate consistently.
Check your state’s rules before setting a rate
Late fee and interest limits vary by state, and some rules distinguish between a flat administrative fee and an interest-style percentage charge. This isn’t a substitute for checking your local requirements — confirm what’s allowed before finalizing your specific number.
The policy matters more than the number
A stated late fee policy changes how a due date reads — from a soft suggestion to a real deadline with a consequence attached. Most of the value comes from the policy existing and being communicated up front, not from how large the fee itself is.
State it on every invoice, not just when it applies
Print the policy on every invoice, even ones you expect to be paid on time. A late fee that only appears after someone’s already late feels like a punishment invented after the fact — stating it consistently removes that impression entirely.
Frequently asked questions
Flat fee or percentage?
A flat fee is simpler to communicate and apply consistently across invoices of different sizes. A percentage scales with the invoice amount, which can feel fairer on very large or very small jobs — either is common practice.
How many days late before the fee applies?
5–15 days past the due date is typical, giving a reasonable grace period before the fee kicks in. State it clearly on the invoice so there's no ambiguity about when the clock starts.
Does stating the policy actually get customers to pay faster?
It helps, mainly because a stated policy signals the due date is a real deadline, not a soft suggestion. The fee itself is less important than the fact that everyone agreed to terms before the job started.
