Everything you need for CIS, in one app

No more separate spreadsheets, no more manual statement formatting, no more month-end reconciliation panic.

Auto CIS Calculations

Apply the correct 20%, 30%, or 0% (gross) rate on every invoice. Material costs are excluded automatically so the deduction sits only on the labour element.

Payment & Deduction Statements

Generate compliant CIS statements for every subcontractor payment. Issue them in one click from the invoice — no spreadsheets, no formatting work.

Monthly Return-Ready Records

Every CIS-tagged transaction rolls up into a monthly summary your accountant or HMRC return software can ingest. Export as CSV or PDF.

Subcontractor Register

Store UTRs, verification numbers, and current deduction rates per subcontractor. Updates apply automatically to new invoices and quotes.

Invoicing That Knows CIS

Raise invoices showing gross, materials, labour, CIS deducted, and net payable. The customer-facing PDF matches what HMRC expects to see.

Audit Trail

Every CIS calculation is timestamped and tied to the originating invoice, so reconciliations and HMRC enquiries are straightforward.

CIS FAQ

Does Traddie handle both contractor and subcontractor CIS workflows?+
Yes. Contractors can record payments to subcontractors with the correct deduction rate, issue statements, and run monthly summaries. Subcontractors invoice gross/labour/CIS deducted in the format HMRC expects.
What CIS deduction rates does Traddie support?+
The standard 20% rate, the higher 30% rate for unverified subcontractors, and 0% (gross payment status). Rates are stored per subcontractor and applied automatically on new invoices.
Are material costs handled correctly?+
Yes. Material costs are excluded from the CIS deduction calculation per HMRC rules — only the labour element is deducted from.
Can I export CIS records for my accountant or HMRC return software?+
Yes. Export monthly CIS summaries and payment & deduction statements as CSV or PDF. Records are structured for direct ingestion by accountants and most HMRC-compatible return software.
Does Traddie submit CIS returns to HMRC for me?+
Not directly — Traddie produces the source records and statements you (or your accountant) submit through HMRC online services or your CIS-return software. The clean monthly export removes the manual reconciliation work.
Is there a free trial?+
Yes — 14 days free on any paid plan, no credit card required. CIS features are available on all plans.
