One wrong category. One HMRC penalty. One very expensive lesson.

Under the Construction Industry Scheme, materials and labour must be categorised separately — and correctly. If a subcontractor invoice that includes both materials and labour is recorded as all-labour, you've under-deducted CIS tax. HMRC will find it. The penalty is rarely small.

On a busy site month, your office manager or accounts admin is handling invoices from twenty subcontractors, four materials suppliers, two plant hire companies, and a scaffolding firm — all arriving at different times, in different formats, some handwritten, some PDF, some forwarded from a site manager's WhatsApp.

Every single one needs to be opened, read, correctly split between materials and labour where applicable, assigned to the right cost code, and recorded before it gets anywhere near your CIS return. At this volume, done manually, errors are not a risk. They are inevitable.

You know the stakes. The volume makes it impossible to get right every time.

Maybe your office manager does her best. She's careful, she's experienced, and she still gets the occasional subcontractor invoice wrong because the breakdown between materials and labour wasn't clear on the document and there was no time to chase it.

Maybe you've had your accountant set up a spreadsheet system. It works when everyone follows it. On a busy week, when invoices are piling up and the site manager is forwarding things via WhatsApp at 7pm, nobody follows the spreadsheet.

Maybe you've already had one HMRC compliance notice. You fixed it, paid the penalty, and told yourself it wouldn't happen again. But the underlying problem — too many invoices, not enough time, no system that catches the split automatically — is still there.

Maybe you're doing the invoices yourself. You know CIS inside out. But you're spending Friday afternoons going through a pile of documents that should have been handled by a system, not the person running the business.

We got a CIS compliance notice for three months of returns where the materials element of combined invoices hadn't been split out correctly. The penalty was £2,400. The fix took two weeks of our accountant's time on top of that.

The problem isn't knowledge. Everyone on your team knows CIS matters. The problem is volume — and the fact that no tool was built to handle construction invoices at this scale.

Built for construction businesses where CIS compliance is not optional.

If you're running a 15–80 person construction or specialist trades business — groundworks, electrical, plumbing, roofing, fit-out — you know that CIS compliance is not a finance problem. It's a business risk.

Your subcontractors depend on you getting the deductions right. HMRC has your monthly returns. One systematic error in how you categorise invoices can trigger a compliance review that costs more in time and fees than you'd spend on proper tooling for a decade.

This was built for that standard. Every subcontractor invoice read, every materials vs labour split identified, every cost code assigned — automatically, before it touches your CIS return.

This isn't for everyone.

Not for you if...

You operate entirely outside CIS — no subcontractors, no HMRC scheme obligations
You process fewer than 50 invoices a month — the time saving and compliance benefit aren't meaningful enough yet
You're on a full construction ERP with built-in CIS processing — you already have this covered

Yes if...

You handle 50–200 subcontractor and supplier invoices monthly under CIS obligations
You've had HMRC query a CIS return or received a compliance notice
Your office manager or accounts admin is spending more than two hours a week on invoice sorting
You use Xero or QuickBooks and need clean, CIS-compliant categorised data

Gmail or Outlook. One click, 60 seconds. We start monitoring every incoming subcontractor invoice, materials delivery, and plant hire charge immediately — including PDFs forwarded from site managers.

Configure your CIS categories and cost codes

Use our construction template — Materials, Labour, Plant & Equipment Hire, Subcontractor Services, Professional Fees, and 8 more — all pre-mapped for CIS compliance. Add your project cost codes so every invoice hits the right job.

Every invoice gets read and CIS-categorised

The moment an invoice arrives, we extract the vendor, amount, date, and VAT — identify whether it contains materials, labour, or both — and assign the correct CIS category. Combined invoices with a materials and labour split are flagged for your confirmation with the breakdown we've identified.

CIS-sensitive items get a short review

Any invoice where the materials vs labour split is ambiguous lands in the review queue with our suggested breakdown. You confirm or adjust in minutes. Nothing goes to your CIS return with a category you haven't approved.

Your CIS return is accurate before your accountant asks

Because every invoice has been correctly categorised throughout the month, your CIS data is clean and complete by return date. No scrambling. No errors from rushed categorisation. No penalties.

CIS return month. Clean data. No surprises.

It's the 18th of the month. Your CIS return is due. You open Xero. Every subcontractor invoice from the past month is already there — materials split from labour, plant hire in its own category, every cost code assigned. The return takes an hour.

There are eleven items in the review queue — combined invoices where we've identified a materials and labour split that needs your confirmation. You're through them in twelve minutes. Every split is confirmed. Nothing ambiguous goes to HMRC.

Your accountant gets clean, CIS-compliant data. The monthly return goes in on time, correctly. The subcontractors get the right deduction. HMRC has nothing to query. And your office manager spent her week on the business, not buried in a pile of subcontractor invoices.

“After our CIS penalty we looked at every option. This was the only tool that actually understood the materials vs labour split — not just as a concept but in how it read the actual invoices. We haven't had a compliance issue since.”

Steve M., Director, 45-person groundworks contractor, Leeds
