What i4 Pay Partners does

i4 Pay Partners (legal entity: i4 Services Limited, Company No. 07027098) is a UK-based umbrella payroll company founded in 2005, headquartered in London. The company acts as an employment intermediary between recruitment agencies and end-clients on one side, and individual contractors, freelancers, locums, and agency workers on the other, processing multiple daily pay runs to deliver same-day payment when funds are received via Faster Payments. Its core offering is umbrella employment services under which contractors become PAYE employees of i4, gaining statutory rights (holiday pay, sick pay, workplace pension, RTI reporting) while i4 handles invoicing, tax, National Insurance, and IR35/AWR/CIS compliance. A specialised i4 CIS product serves self-employed construction subcontractors under HMRC's Construction Industry Scheme.

The technology stack consists of a proprietary CRM system tracking contractor registrations, agency referrals, and payment processing, integrated with an online contractor portal (Myi4) and a mobile app enabling payslip access, timesheet submission, statutory document retrieval (P60s, P45s, P87s), and a real-time Payments Tracker with SMS confirmations. i4 holds FCSA accredited membership, is GDPR-compliant, and publishes Modern Slavery Act statements. The company is founder-operated, with no disclosed external funding or parent entity.

i4 monetises through per-payroll fees deducted from contractor wages, plus margin retained between invoiced agency/end-client rates and net contractor pay; services are free for recruitment agencies. The company is accessed via direct phone registration, an online self-service portal, and referral partnerships with recruitment agencies, with additional revenue potential from an Employee Benefits Platform (discounts, GP, wellbeing) and referral partnerships with Contractor Financial. Scale signals include over 39,000 cumulative contractors served and 11,500 business partnerships across IT, healthcare, social-care, veterinary, hospitality, commercial, and education sectors.

Revenue model

1. Contractor Payroll Processing Fees: i4 Pay Partners generates revenue by charging contractors a fee for payroll processing services. Contractors are employed by i4 and paid through the umbrella structure. The fee is deducted as part of the employment arrangement, with contractors receiving their pay net of fees. The service is free for recruitment agencies to use.
2. Umbrella Employment Services: Revenue is generated through the margin between what i4 invoices to agencies/end-clients for contractor services and what is paid out to contractors as wages, with statutory deductions and fees retained.
