CIS invoice app for UK contractors & subcontractors

For subcontractors

Turn on CIS in Settings and every invoice you raise shows the deduction on labour (20% registered, 30% unregistered) and the amount payable — so contractors pay you the right amount first time. Text CIS REPORT any time for your tax-year deductions-suffered total, ready to offset against your bill.

For contractors paying subbies

Text "CIS invoice John's Electrical, labour £800, materials £300" and GraftG generates an HMRC-style payment & deduction statement PDF: labour, materials, the deduction on labour only, and the net amount to pay. GraftG remembers each subbie's rate for next time.

Deduction on labour only — always right

CIS is charged on the labour element, never materials. GraftG splits them for you and does the maths, including the 30% rate for unverified subcontractors and gross-status (0%) subbies.

Included in the Pro plan

CIS tools are part of GraftG Pro (£24/month) alongside pay-online invoices, branding and automatic payment chasing. First month of Solo free to try the basics.
