Configuring Pay Elements Around How You Actually Pay People

Basic pay, overtime, bonuses, shift allowances and deductions all need configuring correctly before a single payslip is right. pHRism builds your pay structure around how your business actually pays people, not a generic default template.

Use Cases

  • Pay elements, allowances and deductions configured to match your pay structure
  • Overtime, bonus and shift pay rules built in from the start
  • Approval chains and payroll sign-off workflows configured

Getting The Statutory Calculations Right From Day One

Tax, National Insurance and pension auto-enrolment are not optional configuration items, they are where payroll errors become compliance problems. pHRism configures statutory calculations, including SSP, SMP and student loan deductions, correctly before your system ever runs a live payroll.

Use Cases

  • Tax, National Insurance and pension auto-enrolment rules configured correctly
  • Statutory payments including SSP, SMP and SPP built in
  • Student loan deductions and attachments of earnings configured where needed

Proving It With A Parallel Run, Not Just A Test Script

A standard test script does not catch every payroll calculation error, but running your old and new systems side by side does. pHRism runs a full parallel run, comparing actual pay outcomes between systems and investigating every discrepancy before go-live.

Use Cases

  • Full parallel run comparing old and new system pay calculations
  • Every discrepancy investigated and resolved before go-live
  • Your payroll team involved in testing, not just IT

Training Your Payroll Team And Supporting Your First Live Run

A correctly configured system still fails if your payroll team is not confident using it. pHRism trains payroll administrators before go-live, then stays hands-on through your first live pay run so questions get answered on payday, not after.

Use Cases

  • Structured training for payroll administrators before go-live
  • Hands-on support through your first live pay run
  • Clear escalation path if anything looks wrong on payday

Frequently Asked Questions

About payroll system implementation with pHRism

Most pHRism implementation projects run 6-14 weeks from initial scoping to go-live, depending on pay structure complexity, the number of pay groups and how many integrations are required.
A parallel run processes pay through your old and new systems side by side for one or more cycles, comparing the results directly. It catches calculation errors that a standard test script would miss, before they affect a real payslip.
No. Implementation work runs alongside your existing payroll process until the parallel run confirms the new system is accurate, so current pay runs continue unaffected until go-live.
Yes. Statutory Sick Pay, Statutory Maternity Pay, Statutory Paternity Pay and other statutory payments are configured as a standard part of implementation.
This depends on the system and your team’s experience. We scope training needs during discovery and deliver structured sessions covering both routine processing and exception handling ahead of go-live.
pHRism provides hands-on support on the day of your first live pay run, and dedicated support continues through the first few pay cycles before handover to ongoing support.
