Accounting for Plumbers
You're mid-job and you've just fixed the boiler. The customer's asking "Can you invoice me now?" Your current move is scribbling on a scrap of paper and promising to email it next Tuesday. There's a faster way.
Why Accounting Matters for Plumbers
If you're juggling invoices in a spreadsheet or email drafts, you already know the problem — it works until it doesn't. Duplicate invoices, missing VAT on a see pricingk refit, tax deadlines that sneak up. UK plumbers working as sole traders or limited companies need HMRC-compliant invoices, quarterly tax-ready P&L, and a view of cash flow so you know whether you can afford the new van or a second apprentice. Relentify Accounting gives you that without the accountant's bill or the spreadsheet headaches.

Mobile invoicing — Send an invoice the moment you finish the job, no back-office visit required. Add a photo of the receipt right there.
Expense tracking — Snap receipts as you go (materials, fuel, tools). Relentify sorts them automatically; no more carrier bags of crumpled paper at year-end.
Tax-ready reports — Quarterly profit & loss statements, VAT calculations (if registered), and a clean export for your accountant or self-assessment. HMRC-compliant.
Recurring invoices — Set up a standing invoice for regular customers (maintenance contracts, boiler checks). Send it every month with one click.
Cash-flow dashboard — See what's paid, what's outstanding, and what's coming in. No more chasing a see pricinginvoice from six weeks ago.

Frequently Asked Questions
Q: Can I import invoices from my current system?
A: Yes. If you're using QuickBooks, Xero, or Freshbooks, we can pull your customer list and recent transactions directly. If you've been using spreadsheets or email, upload a CSV or just start fresh — most plumbers say a fresh start is cleaner than backfilling three years of chaos.
Q: Do I still need an accountant?
A: That's your call. Relentify gives you tax-ready numbers every quarter. If your accountant charges based on prep-work hours, you'll save there. Some plumbers do their own self-assessment with our exports; others still use an accountant for peace of mind. Either way, you're not paying someone to manually reformat a shoebox of receipts.
Q: Is it HMRC-compliant?
A: Yes. Invoices meet the VAT invoice standard (if you're registered). P&L exports align with self-assessment requirements. We don't give tax advice, but the numbers you send to HMRC are clean.
Q: Can I invoice while I'm on the job?
A: That's the whole point. Mobile app, no login delays, works on spotty WiFi. Photograph a receipt right there and attach it to the expense record — proof at tax time, no more loose papers.
Q: How long does onboarding take?
A: 20 minutes end-to-end if you're starting fresh. If you're importing three years of invoices, plan 45 minutes and a cup of tea, but it's a one-time thing.
