The problem
You started a spreadsheet in April. By June it's three versions behind and you can't remember which contractor is on 20% and which is on 30%.
Your contractor wants a Payment & Deduction Statement. You know you need to send one. You just don't know where to start — so it doesn't happen.
January rolls around and your accountant is asking for your CIS figures. You're digging through bank statements and trying to remember jobs from eight months ago.
CIS sits on top of labour only — not materials. Miss that distinction and your deductions are wrong, your statement is wrong, and your tax return is wrong.
You've got invoices out, some paid, some not. You couldn't tell anyone right now what the total outstanding balance is across all your contractors.
Every year you swear you'll keep better records. Every year April arrives and you're handing your accountant a folder of guesswork.
What CISDesk does
Add a job in under a minute. Gross amount, materials split, contractor, date. CISDesk calculates the CIS deduction and net payment instantly.
Deductions calculated correctly every time — 0%, 20%, or 30% on labour only. No more manual maths, no more mistakes.
Mark jobs as awaiting, paid, or overdue. See your running totals by contractor at a glance — including what's still outstanding.
Your gross, materials, labour, CIS deducted, and net received — all totalled by tax year (6 April to 5 April) automatically.
Generate proper HMRC-format PDFs to send to your contractors or keep for your records. One tap, done.
A complete PDF and CSV bundle of all your jobs, deductions, and year-end totals — ready to hand straight to your accountant.
CISDesk is in beta testing and we're looking for working subcontractors to try it out and tell us what works — and what doesn't. All feedback welcome.
In return, everyone who tests during beta gets free lifetime Pro access when the app goes live on the App Store.
