What you say
“Mike Harris's loft conversion, day three. Eight hours on site — first-fixed the new bathroom, framed the dormer cheeks. £40 for fixings, £180 for the OSB and timber. Stick it on the running invoice.”

The reality
The pain you actually have.
Generic accounting software is built for accountants. This is built for a builder who finishes a job at 5pm covered in dust and just wants to get paid.
01
Big jobs run over weeks, with materials runs every other day, and at the end of the project the invoice is a guess at best. Receipts get lost between van and wallet.
02
CIS deductions get taken at 20% off your commercial sub-work, but the maths at year-end is a shoebox of payment statements and an angry accountant.
03
MTD ITSA starts at £50k from April 2026, then drops to £30k in 2027 and £20k in 2028 — most self-employed builders are in scope by 2027.
What it does
Three things. Built for trades.
No bloat, no “multi-entity reporting”.
Voice-to-invoice for jobs that run over weeks
Big jobs need running invoices, not a panic at the end. Speak each day’s time and materials into Honest Invoices and they stack up against the job. When the job’s done, you press send.
No spreadsheet. No reconstructing six weeks of work from memory. No 20% margin lost to forgotten materials.
CIS labour-and-materials split, automatic
When you’re sub-contracting under CIS, every invoice needs labour and materials shown separately — otherwise the main contractor deducts CIS on the whole lot, including the £3,000 you spent at Travis Perkins.
Honest Invoices splits labour and materials on every line, calculates your CIS deduction at 20% or 30%, and keeps a running total of deductions across the tax year so your year-end reclaim is a one-line figure, not a shoebox of statements.
MTD-ready records, built end-to-end against HMRC
Every invoice you record is a digital record in the format HMRC’s MTD ITSA APIs want. Quarterly updates, BSAS, and the final declaration are all built and tested 16/16 in HMRC’s sandbox — they go live to users the moment our production credentials come through.
The first quarterly deadline is 7 August 2026. If you earned over £50k last tax year, you’re in scope now — starting digital records today is the prep work that matters.
From the founder
Built end-to-end against HMRC’s APIs.
Honest Invoices is built and run by Vix Hawley. The MTD ITSA integration was built by hand — OAuth, fraud-prevention headers, the full Self-Employment Business and BSAS APIs. It took months. The full HMRC sandbox journey passes 16 out of 16 steps with proof on file.
Most accounting platforms are built for accountants. This one is built for builderswho don’t want to spend their evenings doing admin. £15/month. Locked. No price hikes, ever.
FAQ
FAQ for builders.
Do you handle progress invoices and stage payments?
Yes. You can add to a job over weeks of work and send a running invoice at any stage — for a deposit, for the half-way mark, for the snag-list. Each line keeps its date so the customer can see what was done when.
What about CIS deductions on sub-contracted work?
Every invoice tagged as CIS work splits labour and materials, calculates the 20% (or 30%) deduction at source, and contributes to a year-end running total. Your CIS reclaim figure is ready when you sit down to do your Self Assessment — no PDS hunt, no spreadsheet.

I'm a sole-trader builder earning £70k. Am I in scope for MTD ITSA?
Yes — from 6 April 2026. The first quarter ran from 6 April to 5 July 2026, with a submission deadline of 7 August 2026. You’ve got three more quarters to file through HMRC-approved software, plus an annual submission and a final declaration.
Honest Invoices keeps your records in the right shape today and will submit directly through HMRC’s APIs the moment our production credentials land. You have until 7 August.
Will my price go up in two years?
No. £15/month is the price the day you sign up, and the price you’ll be paying in three years. If we launch a higher tier in future, you stay on £15 — locked, in the terms, not just a promise.
Can my accountant still use my data?
Yes. Every invoice and expense exports to CSV, ready for your accountant’s software. We don’t lock you in.
