Subbie is a phone-first CIS invoice for UK subcontractors. Labour and materials on separate lines. CIS comes off labour only. You get a clean A4 PDF from Safari. No account, no monthly fee, no signal needed on site.

£19 once. Yours to keep.

Who it’s for: a CIS subcontractor who invoices a contractor. You know your UTR. You fill invoices on a phone, in the van or on the kitchen table.

What you get: open index.html in Safari or Chrome, add it to the home screen. Name, UTR, CIS status, and bank remembered on the device. Line items flagged labour or materials, CIS at 0% / 20% / 30% (rates editable). VAT optional. Print / Save PDF. No fake HMRC logo.

Not official HMRC software. You still check GOV.UK.

Refund: if you cannot produce a usable invoice within seven days, email me and I’ll refund it.
