How does this skill help me recover unpaid business invoices?

This skill automates the calculation of statutory interest and recovery fees allowed under the UK's Late Payment of Commercial Debts Act 1998, while generating professionally staged reminder emails to help you get paid faster.

Can I use the Late Payment Chaser for consumer debts or international clients?

No, this skill is specifically designed for UK business-to-business (B2B) transactions and should not be used for chasing debts from individual consumers or non-UK entities.

Does the skill calculate the exact interest and debt recovery fees for me?

The skill calculates the 8% statutory interest plus the fixed recovery sums (£40, £70, or £100) based on your specific invoice amount, providing official sources to show your client exactly why they owe the extra fees.

The facts come from a published UK judgment: a contractor was owed £3,256.58 excluding VAT, due on 28 August 2022, and the adjudicator later awarded interest from 29 August 2022 plus £70 compensation. The case was a construction payment application; the skill applies only the general late-payment rules, which give the same start date and fixed sum here.

Before: "A client owes my firm £3,256.58. We sent them the payment application on 31 July 2022 and the final date for payment was 28 August 2022. Today is 30 September 2022 and they still haven't paid. What can I charge them for paying late?"

After (skill output, unedited extract):

Position on 30 September 2022: The last day to pay on time was 28 August 2022; interest runs from 29 August 2022 (33 days). Assumes the customer is a business.

Item	Amount	Basis
Unpaid invoice	£3,256.58	your figure
Interest to 30 Sep 2022 (33 days at 9.25%)	£27.23	8% + Bank Rate of 1.25% on 30 June 2022 (Rate of Interest (No. 3) Order 2002, art. 4)
Fixed sum	£70.00	Late Payment of Commercial Debts (Interest) Act 1998, s.5A
Total today	£3,353.81	interest adds £0.83 a day

The start date and the £70 match what the adjudicator awarded in the real case. The three emails follow in the same answer.

About this skill

Chases one late business invoice for UK freelancers, consultants and small suppliers. Works out the statutory interest (8% over the Bank of England base rate) and the fixed £40 / £70 / £100 recovery sum under the Late Payment of Commercial Debts (Interest) Act 1998 with a script, shows the working with official sources, and writes staged reminder emails ready to send. Use when the user says "my client hasn't paid my invoice", "invoice is overdue", "chase a late payment", "how much late payment interest can I charge", "write a payment reminder", "statutory interest on an unpaid invoice", or gives an invoice amount and date and asks what to do about non-payment. UK business-to-business invoices only; not for consumer debts and not legal advice.
