The reality
The pain you actually have.
Generic accounting software is built for accountants. This is built for an electrician who finishes a job at 5pm covered in dust and just wants to get paid.
01
CIS deductions get taken at 20% off your commercial sub-work, but most sparkies have no clean total of what they're owed back at year-end.
02
Customers pay £400 callouts on the spot but ghost £4,000 rewires for six weeks. You don't have time to chase, and you don't want to be rude.
03
Domestic callouts get paid in cash on the doorstep — sometimes a card, sometimes a bank transfer — while commercial periodic-test work spans three visits over six weeks and gets invoiced in one go. Reconciling the two against the same year-end Self Assessment is where the December evening disappears.

What it does
Three things. Built for trades.
No bloat, no “multi-entity reporting”.
Voice-to-invoice that speaks electrician
Describe an EICR, a fuse-board upgrade, a fault-find, a Part P-notifiable circuit, in the words you actually use. The AI extracts the time, the parts, the customer name, and builds a UK-compliant invoice with sequential numbering, your business details, and your payment terms.
No typing on a tiny phone keyboard at 6pm. No remembering what you did Monday on Friday.
EICR and Minor Works certificate referencing on every line
Every invoice line can reference the certificate it belongs to — EICR report number, Minor Works Certificate (MWC) serial, the Building Control notification reference for Part P-notifiable work, the schedule of inspections appended. When the customer queries the bill, when a landlord forwards your invoice to their letting agent, when a domestic client sells the house and the buyer’s solicitor asks for the electrical paperwork — the invoice is the index. Commercial periodic-test pipelines that run across three visits stay grouped against the same EICR report, so labour and materials add up across the job, not against each van trip.
CIS labour-and-materials split, automatic
When you're sub-contracting on commercial sites under CIS, every invoice needs labour and materials shown separately — otherwise the contractor deducts CIS on the whole lot, including the £700 you spent at City Electrical Factors.
Sparkies have an unusual CIS shape — domestic EICRs and fault-finds are paid gross, but commercial periodic-test contracts routed through a maintenance contractor have CIS deducted at 20% or 30%. Year-end reclaim usually hangs on which of those two pots was bigger. Honest Invoices flags each invoice at creation and gives you a CIS-deducted total cleanly separated from your gross-paid domestic income.
MTD-ready records, built end-to-end against HMRC
Every job you record — EICR, Minor Works Certificate, Part P-notifiable rewire, fuse-board upgrade, fault-find — is a digital record HMRC’s MTD ITSA APIs recognise. Quarterly updates and BSAS are fully tested in HMRC’s sandbox environment (16/16), with production approval in progress — they go live the moment our production credentials land. Final Declaration support is planned for the following release.
Electricians often have heavy first-fix months followed by EICR-renewal-heavy months — your quarterly figures shift sharply depending on the calendar. Digital records from 6 April 2026 mean the 7 August submission isn’t a reconstruction exercise from receipts in a glovebox.
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 electricianswho don’t want to spend their evenings doing admin. £15/month. Locked. No price hikes, ever.
FAQ
FAQ for electricians.
Do you handle EICRs and other electrical certificates?
Honest Invoices is invoicing software — it doesn't generate or store the EICR / MWC / EIC certificate itself (you'll keep using your existing certification software for that). But every invoice line can reference the certificate number, the date, and the property address, so your invoice and your certificate trail line up at year-end.
Native certificate generation is on the roadmap once we've got the core invoicing flow rock-solid for our first cohort of electricians.
What about CIS deductions on commercial sub-work?
Most domestic electrical work isn’t CIS — EICRs, fault-finds, rewires direct to the homeowner are paid gross. What is CIS is commercial periodic-test work for a maintenance contractor, electrical sub-work on shopfits, or site work through a principal contractor. Honest Invoices flags the difference at the invoice stage and tracks the year’s CIS-deducted total separately from your gross domestic figure.

I'm a sole-trader sparky earning £55k. Am I in scope for MTD ITSA?
Yes — from 6 April 2026. A jobbing sparky on £55k from a mix of domestic callouts and commercial EICR work is in the first wave from day one. The first quarter covers 6 April to 5 July with a 7 August 2026 submission deadline. Three more quarters follow, plus an annual submission and a final declaration after year-end.
Honest Invoices keeps your digital records in the right shape now, and will submit directly through HMRC's APIs the moment our production credentials land. Full plain-English breakdown: 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.
We've watched accounting software prices triple over five years. We're not doing that to you.
I do mostly cash-in-hand domestic work. Is this still useful?
Yes — but with a caveat. If your turnover is below £20k a year, MTD ITSA doesn't apply to you yet (April 2028 threshold). Honest Invoices is still useful for chasing payment and keeping records clean, but the MTD-submission features won't be a draw. Once you're over £20k it becomes mandatory.
Can I keep using my own bank, accountant, and certification tools?
Yes. Honest Invoices is invoicing + MTD submission. You keep your existing bank account, your existing accountant (we export CSV for them), and your existing certification software. We don't try to be everything — we try to be the best at the bits we do.
