Move payroll with proof before go-live
Keep the incumbent spreadsheet or system running while the new calculation is tested employee by employee. Resolve differences across multiple cutoffs before changing the payroll of record.
A three-cutoff implementation path
The exact programme can change with payroll complexity, but every launch should make data, rules, exceptions and final acceptance visible.
Map and baseline
Import employee, compensation, DTR and incumbent payroll data. Confirm mappings and current policy assumptions.
Run and explain
Calculate independently, compare employee-level amounts and resolve differences without overwriting evidence.
Validate and graduate
Complete clean parallel cutoffs, approval, bank and agency checks, security evidence and a controlled go-live decision.
Go-live is a checklist, not a date on a slide
The implementation workspace tracks responsible owners, client requests, mapping status, parallel results, bank and agency validation, MFA, backup and support readiness.
| Gate | Evidence | Owner |
|---|---|---|
| Payroll accuracy | Clean parallel cutoffs and explained exceptions | Payroll practitioner + client |
| Payment | Accepted bank test for the selected entity and format | Finance + bank |
| Statutory close | Validated BIR and agency preparation outputs | Employer + adviser |
| Security | MFA, access review, backup restore and deployment checks | Operations + security |
Prove the next cutoff before replacing the current one
Start with historical or anonymised data and compare the result against your existing process.
