This guide takes you from zero to your first pay run. If you’re brand new to Flow Payroll, follow it top to bottom. Each step links to a deeper guide if you want more detail.
Flow Payroll uses UK payroll terms throughout — PAYE, NI, RTI, FPS, EPS, P45, P60. If any are unfamiliar, the key concepts guide explains them.

​
Before you begin

You’ll get set up faster if you have these to hand:
  • Your organisation’s PAYE reference and Accounts Office reference from HMRC.
  • Your HMRC Government Gateway credentials for RTI submissions.
  • Each employee’s personal and employment details (name, address, date of birth, NI number, start date, tax code, and pay).
  • Your pay schedule — how often you pay people (weekly, fortnightly, four-weekly, or monthly) and the pay day.

​
Set up in five steps

4

5

Submit to HMRC and share payslips

Send your Full Payment Submission (FPS) to HMRC, then send payslips to your team.HMRC & RTI → · Payslips →

​
What happens next

Once your first pay run is done, most months follow the same rhythm:
  1. Review who’s being paid and update anyone whose pay or details changed.
  2. Add any statutory payments, pension changes, or court-order deductions.
  3. Run the pay run and submit the FPS on or before pay day.
  4. Submit your EPS at month-end if you have anything to report.
Set a recurring reminder for your RTI deadlines. The FPS must reach HMRC on or before each pay day, and the EPS is due by the 19th of the following tax month (the 22nd if you pay HMRC electronically).
