Built for plumbers, not for accountants.

Boiler swap quote in 60 seconds

Pre-loaded plumbing library: combi boiler, system, unvented cylinder, copper 15 / 22 / 28, push-fit, gate valves, expansion vessels. Drop the lines, add labour, VAT auto-applied per line. The client signs with a finger on the screen and the PDF goes by WhatsApp before the toolbox is back in the van.

One job, three languages, one VAT number

Quote the Polish-passport homeowner in PL, deliver the invoice in DE to the German office paying the bill, send the English copy to the UK procurement chain. MarginTap is the only invoicing app for tradesmen that handles three documents on one job with the same VAT number — no translator, no re-typing.

Offline in the boiler room

Cellar, basement, lift shaft, rural call-out — MarginTap keeps writing. When reception comes back, the quote sends itself. No more "I'll write it up at the office tonight" and never doing it.

Plumbers — your questions

Can I quote a Polish-speaking homeowner in PL and invoice the German office in DE on the same boiler swap?
Yes — that's the moat. Build the quote once, switch language with one tap, the PDF re-renders in Polish for the homeowner and in German for the office that pays. Both documents reference the same job number and the same VAT number. No translator, no re-typing, no other invoicing app for tradesmen does this.
Burst pipe at 10 pm. Can I quote from the van right there?
Yes. Pick from the library (copper 22, push-fit, isolation valve, drain-down, callout), the customer signs with a finger on the screen, the PDF goes by WhatsApp to the insurer before midnight. No signal in the basement? MarginTap stores locally and syncs the second the 4G comes back.
I'm a Polish plumber based in the UK working German rentals — does VAT actually stay correct?
Yes. Per-line VAT supports standard, reduced, zero-rated, reverse-charge and exempt. Set the default per client (your UK customers on UK VAT, your DE customers on DE reverse-charge for B2B), override per line when a reduced rate applies. The export to your accountant lands clean — one VAT number, line-by-line breakdown, no manual reconciliation.
Does it work without internet — I lose signal in basement boiler rooms every job.
Offline-first by default. Every quote and invoice writes to local storage on the phone. Lift shafts, cellars, half-built sites, ferries between IE and UK — MarginTap keeps working. The send queue flushes the moment reception returns and the PDF lands in WhatsApp without you touching it twice.
How do I show the boiler manufacturer's commissioning certificate or warranty terms on the quote?
Add the certificate reference in the line description or the quote footer ("Worcester Bosch Greenstar 8000 — 10-year manufacturer warranty, conditional on annual service"). MarginTap preserves the text verbatim when you convert quote to invoice, so the warranty trail survives the signature.
Why €9.99/month when Tradify, Powered Now and Jobber charge per user?
Because plumbers aren't agencies. MarginTap is flat €9.99/month, one trader, unlimited quotes and invoices, no per-seat tax. €79/year saves 34%. 14-day Pro trial, no card to start, cancel from the app. CSV export to your accountant is included on every tier.
