Why these, and what's next
Each tool answers a question trades ask us every week: how much CIS will come off this payment, what day rate actually pays the bills, is this price a good margin or just a good markup, and what can I add to an invoice that's two months late. They use the same rules our guides explain, with the sources linked on each page.
More are on the way. If there's a sum you do by hand every month, tell us on WhatsApp and it may be the next one. For the bigger picture, start with our guides for UK trades and builders.
Where Nexley fits
Nexley prices your tenders and runs your office, all on WhatsApp. These tools do one sum at a time. Nexley does the work around them: it measures take-offs and prices tenders on your own rates, turns a voice note into a quote, drafts invoices, chases late payers, and prepares CIS and VAT, with you signing off before anything goes. See what Nexley is, or how it handles the back office.

Does what it says really. Compared to what I'd have to pay someone to do everything they're looking after, it's worth it.”
