Fewer CIS clean-up jobs at month end

What lands in your inbox

• Every payment, split

  Labour, materials, VAT and the CIS deducted, per payment.

• A month that adds up

  A spreadsheet of every payment in the month. Its CIS column equals the month's figure.

• Filed months locked

  Nothing moves after filing. Reopening needs a reason, and it is logged.

• Right to work evidence

  Checks with dates and photos, and an audit pack per worker.

Check our maths

We have written down our assumptions and worked examples: CIS on labour only, VAT left out, round down, reverse charge. We want a qualified accountant to check them before any firm relies on them. 15 minutes of your time is all we ask to start.

What works today, and what does not

Live: CIS calculation, pay runs, CSV payment list (a bank-format file is built but not yet tested with a real bank), month figures, right to work, worker app in six languages.

Not live yet: filing the CIS300 from the app (you or your client file as now), the real HMRC check, and bank-format file tests with a real bank. We say so in the app. Coming: Xero and QuickBooks bill files.

For you

• Free use for your clients during the trial.
• If you want, a referral share on any firm you bring, agreed in writing first.

Software only

Subbo never holds client money, and the firm remains responsible for its tax. Nothing here replaces your judgement.
