For 47 days, you have been your client's bank - a $4,800 interest-free loan they never asked you to approve.
That is $1,335 a year in interest you are owed - and $57,600 of your money spending its time in other people's accounts.
Heads up: late fees are only enforceable if they are written into your contract, and some states cap the rate - check yours. This is math, not legal advice.
The best late fee is the one you never charge. MotionOps sends the invoice the day the job closes, chases it automatically, and takes card payment on the spot - so this page stays theoretical.

Turn the rate in your contract into a yearly rate (1.5% a month × 12 = 18% a year) and charge it by the day: invoice × yearly rate ÷ 365 × days overdue. Example: $4,800 × 18% ÷ 365 × 47 days = $111. Check that your contract and your state’s rules allow the fee you charge.
