Buyer decision guide

Should you DIY, run the free checker, buy The CIS Monthly Reconciler, or hire help?

UK construction contractors and bookkeepers turn a month of CIS payment data into reviewable deduction calculations, payment-and-deduction statements using HMRC-listed fields, a CIS300 review summary, and a sign-off checklist without uploading subcontractor data.

Decision matrix

Choose the route that matches the risk.

01

DIY from public guidance

Use this when the issue is low-risk and you have time to read primary sources, build your own checklist, and keep evidence yourself.

02

Run the free diagnostic first

Best first move when you need a fast private screening result before buying anything.

03

Use the paid kit

Best fit when the problem is recurring, evidence-heavy, and specific enough that a buy-once workflow is cheaper than rebuilding from scratch.

04

Hire qualified help

Use this for legal, tax, medical, employment, accessibility, compliance, regulated, disputed or high-value cases where judgement matters.
