Contractor Payroll Finance UK FAQ

What is contractor payroll finance?

Specialist UK working capital finance for recruitment agencies running contractor desks. Funds weekly contractor payroll outflow against monthly client invoice inflow, with built-in IR35, umbrella, AWR and CIS handling.

How does IR35 affect contractor payroll finance?

Inside IR35: contractor must be paid via PAYE (no personal service company allowed for off-payroll engagements). Outside IR35: contractor invoices through their own limited company (PSC) with no PAYE deduction. Sonovate handles both modes with a Status Determination Statement (SDS) tool for each contract. The finance provider doesn't carry IR35 liability (that sits with the agency or end-client) but their tech makes status determination easier.

Umbrella vs PSC vs PAYE payroll routing?

Three routes: (1) PAYE direct: contractor employed by agency, agency runs PAYE, simplest but agency carries employment liability. (2) Umbrella: contractor employed by umbrella company (NoPalaver, Parasol, Brookson), agency pays umbrella, umbrella runs PAYE. Reduces agency liability. (3) PSC: contractor's limited company invoices agency, agency pays gross, contractor handles tax. Only for outside-IR35 engagements. Sonovate supports all three routes.

Best contractor payroll finance UK?

Sonovate dominant for IT, tech and engineering contractor desks. Bibby Financial Services for established agencies (£2m+) with separate payroll bureau. IGF Invoice Finance for sub-£500k startups. Specialist umbrellas (NoPalaver, Parasol) sometimes provide funding-light models for smaller agencies.

Cost of contractor payroll finance UK?

Sonovate (all-in bundle): 1.5-3% of contractor invoice value. Bibby (factoring + separate payroll bureau): 0.5-2% factoring + £15-25/contractor/week. IGF (selective factoring): 1-2%. For a typical 15-contractor IT agency at £700/day each, all-in cost is 10-20% of agency margin per contractor.

Healthcare locum agency finance?

Locum recruitment (NHS doctors, nurses, AHP) uses the same underlying contractor payroll finance, with two specifics: NHS Standard Contract terms (typically 30-day payment), framework agreement compliance (Health Trust Europe, NHS SBS), and IR35 inside-determination across most NHS engagements. Sonovate and Bibby both serve healthcare locum agencies actively.
