Looks good for Q2. One statement missing from Harwood Build, I've chased it.
CIS first
Built for CIS, not adapted to it
Generic bookkeeping apps treat CIS as a checkbox. Graft starts there, because that is where your money actually goes. Deductions done right at 20%, 30% and gross, and most subbies are owed a chunk of it back.
Every deduction tracked against the contractor who made it. You can see exactly who has taken what, all year.
When a deduction statement does not turn up, Graft flags it. You chase it in the month it went missing, not the week the return is due.
Most subbies are owed money at year end. Your reclaim builds on screen through the year, so you watch the number instead of guessing it.
Invoices that show the deduction the way contractors expect, so they get paid without a phone call about the maths.
Admin, handled
The boring stuff does itself
The books fall behind because doing them means sitting down after a ten-hour day. So Graft does them while you work.
Drive to site, drive to the merchant, drive home. Trips log themselves at 55p a mile (25p past the threshold). Mark them business or personal with a swipe.
Point the camera at a receipt and it is read for you. You confirm with a tap. Nothing goes in the books without your say so.
Connect your bank through Open Banking, via TrueLayer, a licensed provider. Income lands, gets matched to the right contractor, done.
Not going it alone
Your accountant is in the app
Graft is not trying to replace your accountant. It gives them a live window into your year, so January stops being a scramble for both of you.
The portal shows your accountant who is up to date and who is drifting, months before the deadline. If something is missing, you both know.
Ask a question from the van. Send a photo of the letter that just landed. No email chains, no waiting for office hours to ring.
MTD quarterly updates go to HMRC from the app, with your accountant across the numbers before anything is sent.
The portal is free for practices, and stays free. Most traders arrive because their accountant invites them. If yours has not heard of Graft, send them this page.
Making Tax Digital
MTD is here for sole traders
MTD for Income Tax replaces the single January return with quarterly updates to HMRC. Mandation is live, and it widens in stages by income. Graft is ready now.
From April 2026
Already live. Sole traders over £50k are in now, and the first quarterly deadline is 7 August 2026.
From April 2027
Sole traders over £30k join next year. That is most full-time subbies.
From April 2028
Over £20k and you are in by 2028. Nearly every trade ends up here.
Four updates a year is miserable from a spreadsheet. From Graft, the quarter is already logged by the time it is due, and your accountant signs it off in the app.
What you get
The whole year, in your pocket
Tax owed, live
What you owe so far, what CIS has already taken, and where your reclaim stands. One screen, all year, not a surprise in January.
A tax pot you keep yourself
Graft suggests a figure to set aside as a soft target. The money stays in your own account. Graft never holds a penny of it.
Payments on account, explained
The July payment that catches everyone out. Graft shows it coming months ahead and folds it into the pot suggestion.
VAT and reverse charge warnings
A warning as turnover heads for the VAT threshold, and a flag on jobs where the domestic reverse charge applies, before you invoice them wrong.
Sole trader vs Ltd, compared
A straight comparison on your actual numbers, ready to take to your accountant. A starting point for that conversation, not a verdict.
Works offline
Log trips, receipts and income with no signal at all. It syncs when you are back in coverage. Built for sites, not offices.
Pricing
One price, and the portal is free
£9.99 plus VAT a month after a free week. The accountant portal costs practices nothing. It is on the App Store and Google Play, there is more at graft.capstonesoftware.co.uk, and if you would rather have it on paper, the two-page explainer (PDF) says it all.

Questions
Straight answers
Is Graft on iPhone and Android?
Both. Graft is live on the App Store and on Google Play, and there is a web app in any browser if you would rather not install anything. Same account, same numbers, whichever you use.
Does Graft hold my money?
No. Graft never holds, moves or collects your money. The tax pot is a suggested figure to set aside in your own account, a soft target you control. Everything in the app is tax admin guidance, not financial advice.
What does my accountant see?
Through their free portal: your income, expenses, CIS deductions and tax position, plus flags for anything missing. They also get the two-way chat. They see your books; they never touch your money, and neither does Graft.
Does it work offline?
Yes. Graft is built offline-first. No signal in the basement or halfway up a scaffold, log it anyway. Everything syncs when you are back in coverage.
How does the free trial work?
Signing up is two fields: email and password, or one tap with Google. No card needed, cancel any time. The full app is free for 7 days, then £9.99 plus VAT a month. The accountant portal costs practices nothing either way.
Twenty seconds of it
Watch a day keep its own books
The refund builds, a trip logs itself, a receipt gets confirmed, your accountant chimes in. Straight books, no shoebox.
A week on the house
Two fields and you're in: email, password, done. No card needed, cancel any time. If Graft does not beat the spreadsheet, walk away and pay nothing.
