Nearly everyone chases the original figure and leaves the recovery fee and the interest on the table.
UK late invoice workspace
Add £40–£100 to that overdue invoice. Legally.
When a business pays you late, the law is on your side: a fixed recovery fee set by the size of the invoice, plus interest at 8% over the Bank of England base rate. ChaseKit works out your number and writes the email that asks for it.
You don't have to charge it. Naming the number is usually enough.

Figures follow GOV.UK guidance
Why it exists
Most freelancers ask for too little.
Firm without rude is hard to write when you are annoyed. ChaseKit writes it, and you decide how hard it lands.
Daily interest, fee bands, due dates. Wrong figures undermine the ask at the exact moment it needs to land.

3. Send the right follow-upCopy the free email, or unlock the editable recovery workspace when you need the full record.

Private by design
Your invoice details stay local.
ChaseKit is a static, local-first tool. It keeps draft cases and profiles in your browser storage. It does not upload invoice files to a ChaseKit server. If you open Gmail, Outlook, or your mail app, the draft text is passed to that provider so you can review and send it there.
