FREE TRADE TOOLS
Free tools for UK trades.
Quick calculators built for a phone in the van. No sign-up, no email, no catch — use them as often as you like.
Late payment calculator
Work out the statutory interest and compensation you can legally charge on an overdue invoice, and copy a ready-made notice.
Open toolCIS deduction calculator
Split labour from materials and see the CIS deducted at 20% or 30%, plus what actually lands in your account.
Open toolChaser message generator
A polite nudge, a firm reminder or a final notice — written for you and ready to send by text or WhatsApp.
Open toolBuilt around the money side of the job
Every one of these came out of the same three questions UK trades ask: what can I charge when someone pays late, what should this job actually be priced at, and how do I say something about an unpaid invoice without falling out with the customer.
They work on a phone, they don't ask for your email, and nothing you type is stored. Plumbers, electricians, carpenters, builders, roofers and groundworkers — all of it is set up for UK rules, from CIS deductions to statutory interest.
Stop chasing. Get paid on the job.
Paid30 gives your customer a small discount for paying within 30 minutes, by card, Apple Pay or Google Pay. Most settle before you've packed the van.
