Last updated: June 2026

Free tools to help UK businesses work through an overdue B2B invoice. Calculate the statutory interest and compensation you may be able to claim, check whether you are ready to send a Letter Before Action, and run a checklist before any pre-action or court step. These tools are software aids for organising your own recovery evidence — they do not provide legal advice.

Late Payment Interest Calculator

Work out the statutory interest (8% plus the Bank of England base rate) and fixed compensation you may be entitled to claim on an overdue B2B invoice.

Letter Before Action Readiness Checker

Check whether you have the evidence and notice period in place before sending a Letter Before Action to a business or sole-trader debtor.

Court Readiness Checklist

Run through the records and steps to organise before any pre-action or court stage, so your overdue-invoice evidence is in order for internal or solicitor review.
