Late fee invoice: how to bill overdue charges honestly

Late fees only stick when the original invoice had a due date, the client agreed to the fee in writing, and the follow-up invoice is calm and specific.

How to structure the PDF

FieldExample
New invoice numberINV-0042 (do not reuse the overdue invoice's number)
LineLate fee on INV-0038 (due 1 Sep, still unpaid as of 3 Oct) — 2% as per MSA §7
NotesOriginal principal remains due. Pay INV-0038 + this fee. Fee stops accruing when principal is paid.
AttachmentOptional: copy of the original PDF
Late fee invoice example

Fairness beats aggression

A small, documented fee plus a phone call usually recovers more than a hostile PDF. If the client is waiting on your revision, fix that first — then fee.

Tracking overdue in Kitebill

In the app, invoices marked Sent that pass their due date become Overdue automatically. That is a status for you; it does not email the client or invent a fee. See overdue invoice tracker.

What we do not do

No automatic late-fee engine, no collections agency, no legal threats. You type the fee you are allowed to charge. Not legal advice.

Questions

Can I add the late fee onto the original invoice?

Better as a new invoice referencing the old number — cleaner for AP and for your records.

Does Kitebill auto-charge late fees?

No. Status becomes overdue; fees are manual.

What % is normal?

Whatever your signed terms say. Do not invent a rate after the fact.
