CISflow
Early access — building in the open

Stop typing CIS invoices. Forward them. Done.

Forward a subcontractor invoice and CISflow does the CIS data entry for you — UTR, labour/materials split, deduction rate, all read off and ready to post to Xero. You check the figures and approve. The monthly re-keying grind, gone.

The CIS300 return is due the 19th, every month. Miss it and HMRC penalties start at £100 — then £200 at two months, and climb.

Start free — no card. 14-day trial, cancel anytime.

Three steps.
Then the 19th
takes care of itself.

From inbox to Xero, with you in control of every figure along the way.

  1. Forward the invoice

    Email your subcontractor invoice to your CISflow address. PDF, scan, photo — whatever arrives in your inbox.

  2. Review the extraction

    CISflow pulls UTR, verification number, labour/materials split, deduction rate, and net pay. You check every figure before anything moves.

  3. Export to Xero / CSV

    Approve with one click. A clean CIS bill goes into Xero, or download as CSV for QuickBooks or your CIS300 return.

One messy invoice in.
One clean CIS bill out.

Every month, the 19th comes for you

Pull each subbie's PDF, type the UTR, check the labour/materials split, enter the deduction rate — for every contractor client, every month, racing a hard HMRC deadline where one slip carries a penalty. The CIS maths is easy once the data's in; it's the manual entry that eats your days and holds the risk.

  • Forward an invoice → CIS fields out, no typing.

    UTR, verification number, labour/materials split, deduction rate — extracted and structured, ready to review.

  • Review-and-approve before anything posts — you stay in control of every figure.

    CISflow never posts without your sign-off. Every number is yours to check. You remain responsible for what goes to HMRC.

  • Built for bookkeepers running CIS across multiple contractor clients.

    One login, all your clients. The more CIS work you carry, the more time this buys back before the 19th.

SECURITY & DATA

Your clients' data, handled properly

You're a fiduciary for your clients' records. Here's exactly how we treat their data — stated honestly, including what's still in progress.

  • UK-region storage, under UK GDPR

    Your account and extracted CIS records are stored in our UK-region (London) database, under UK GDPR.

  • 256-bit encryption, in transit and at rest

    Documents are encrypted on the wire and on disk.

  • Raw files aren't kept; you can delete your data

    Uploaded files aren't kept as an archive — only the extracted CIS fields stay in your account. Delete your account and that data is removed.

  • AI extraction runs via a US provider

    Invoice content is read by OpenRouter, a US-based AI provider, for the extraction step. We disclose this on our privacy page.

  • ISO 27001 & Cyber Essentials — in progress

    Both are in progress and targeted before launch — not yet held.

  • You approve every figure before anything posts

    Nothing is written to your books without your sign-off.

  • You stay responsible for what's filed

    We're a data-entry tool, not your accountant — accountability stays with you.

Items marked “in progress” are not yet certified — we'll only claim a standard once it's formally held.

FROM THE TEAM

We're building this in the open

We kept watching bookkeepers lose evenings before the 19th — splitting labour from materials, looking up rates, and re-keying every subcontractor invoice by hand. The CIS maths was never the problem; the typing was. So we built the thing that kills it.

CISflow is new and live in early access. We won't dress it up with fake reviews or logos — instead, the product is right here to try. Forward a real invoice, or open the demo, and judge it yourself. You review and own every figure; we just kill the typing.

The maths above takes about 20 secondsin the demo. By hand it's open the PDF, key the UTR, split labour from materials, look up the rate and work the deduction — every subbie, every month, racing the 19th.

FAQ

Your questions, answered.

What types of invoice does it handle?
PDF invoices, email attachments, and scanned documents. If you can forward it as an email attachment, CISflow can read it — even messy hand-typed layouts.
Who is responsible if a figure is wrong?
You are — and that is by design. CISflow is a data-entry tool, not an accountancy service. You review every extracted field and approve before anything posts. We assist; you are accountable.
Does it work with QuickBooks as well as Xero?
The first version exports clean CSV that imports into any accounting package. Native Xero write-back ships first; QuickBooks follows.
How is my client data protected?
Your account and the extracted CIS records are stored in our UK-region (London) database under UK GDPR, isolated to your account. Raw uploaded files aren't kept as an archive. To read the figures, invoice content is sent to OpenRouter, a US-based AI provider, for the extraction step — we disclose this and the full picture, including sub-processors and your rights, on our privacy page. ICO registration and a written data-processing agreement are on our to-do list, not yet completed, and we say so plainly.
Is CISflow available now?
Yes. CISflow is live in early access — create an account, start a 14-day free trial with no card, and forward your first invoice today. We're building in the open, so early members lock in the founding price and help shape what ships next.
What does it cost?
Two plans: Solo at £39/mo for a single bookkeeper or contractor, and Practice at £99/mo for running CIS across multiple contractor clients. Both start with a 14-day free trial and need no card to begin — see the pricing page for the full breakdown.
