Payroll that works the way you do

Payroll is one of those jobs where boring is good. Pay slips on time, taxes calculated right, HMRC submissions filed without drama. That’s what we deliver — for sole-director companies, growing teams and established SMEs.

We handle the lot: weekly or monthly cycles, statutory sick and maternity pay, auto-enrolment, P11Ds for benefits, year-end P60s, and the awkward stuff like leavers, joiners and back-pay. Your team get clear payslips through a secure portal. You get a single number to call if anything’s odd.

We will register you for PAYE at HMRC, set up auto-enrolment with NEST or your chosen pension provider, and run the first payroll within a week.
Do I have to offer a pension?
Yes, auto-enrolment is mandatory for UK employers with eligible employees. We handle the setup and ongoing contributions.
Can I payroll benefits-in-kind?

What about CIS for construction?
Covered, we handle subcontractor verification, monthly CIS300 returns and CIS deduction certificates.
