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.
Your number and a friendly reminder are free. If they ignore it, escalate with a formal statutory statement for £7.

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.
How it works
From unpaid invoice to ready-to-send chase in three steps.
1. Enter three detailsWho owes you, how much, and when it was due. Or auto-fill from your invoice file.
2. See your numberThe original amount, statutory interest, the fixed recovery fee and the total you can claim.
3. Send, then escalate if neededSend the free friendly reminder. If it is ignored, the £7 pack gives you the formal statement and the firm and final notices.
Free vs paid
Emails get ignored. Formal statutory notices get forwarded to accounts.
Your calculation and a friendly reminder are free, with no account. When the friendly reminder is ignored, the £7 escalation pack gives you a statutory late payment statement and a notice of claim to attach, both citing the Late Payment of Commercial Debts (Interest) Act 1998, plus the firm reminder and final notice. Everything is filled in for that invoice and sent in your name, not ours.

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.
