Payroll migration that proves accuracy before go live.
Payroll migration and payroll data migration move pay data, rules, and processes into a new platform with control. Strong payroll system and data migration reduces errors, protects compliance, and shortens time to a clean first run. It aligns pay elements mapping, proration, HMRC checks, and a clear cutover plan. With parallel payroll we compare outputs by variance, not opinions. The result is confidence for HR and Finance and calmer month end cycles.
Discovery & Inventory
We start payroll migration with a precise inventory of sources, pay groups, calendars, and control points. We catalogue base pay, allowances, deductions, benefits, pensions, and year to date balances. Owners and data quality are confirmed early. This baseline keeps payroll data migration decisions grounded and gives leaders a clear view of risks, timelines, and what will change as part of payroll system and data migration.
Pay Elements Mapping
Bad mapping creates endless fixes. We design pay elements mapping with rules for codes, tax treatment, proration, and rounding. We standardise names and set default handling for edge cases like mid period joiners and leavers. Documentation shows every transformation so payroll teams trust outcomes. This gives payroll data migration a stable backbone and reduces reconciliation noise later.
Validation & HMRC Checks
Evidence beats assumptions. We run layered validation across counts, totals, tax and NI calculations, and pensions. HMRC checks cover RTI readiness, PAYE, NI categories, and student loans. Reconciliations track before and after balances. Issues are logged with root causes and retested to zero. This discipline makes payroll migration audit ready and predictable.
Parallel Payroll & Variance
Parallel payroll is how we prove results. We run side by side cycles and compare outputs at employee and total levels. Variances are explained and resolved, including proration, retro, and rounding. Reports, journals, and RTI files are verified. By proving accuracy in parallel, leaders sign off payroll system and data migration with confidence and no last minute surprises.
Cutover & Hypercare
Go live needs choreography. We script a cutover plan with timings, signers, and rollback steps. Banking approvals, submission windows, and contingency plans are set. Hypercare covers the first cycles with daily checks, variance dashboards, and fast fixes. We hand over a tuned runbook so payroll migration value compounds.

Discovery and Design
We align goals, risks, and timelines, then design payroll migration across data, rules, and controls. We document payroll data migration standards, pay elements mapping, proration, HMRC checks, and a first pass parallel payroll plan. This keeps payroll system and data migration traceable with clear acceptance criteria for sign off.
What We Offer: - Source inventory and data profiling
- Pay groups, calendars, and control design
- Pay elements mapping and proration rules
- Validation standards and reconciliation checks
- Parallel payroll and cutover milestones

Build, Validate, and Cutover
We run repeatable loads, automate checks, and resolve defects to zero. We complete HMRC checks, prove RTI readiness, and run parallel payroll with variance dashboards. The cutover plan is rehearsed and executed, then supported by hypercare so the first cycles are stable and clean as part of payroll data migration.
What We Offer: - Repeatable load pipelines and logs
- Automated and manual validation packs
- HMRC checks and RTI readiness proof
- Parallel payroll variance analysis
- Cutover rehearsal and hypercare

Frequently asked questions
About Our Payroll System and Payroll Data Migration Services
What is payroll migration and why does it matter?
Payroll migration is the structured move of pay data and rules into a new platform. Done well, payroll data migration reduces errors, protects compliance, and improves reporting. It sets up clean first runs and calmer month ends.
How do you approach pay elements mapping?
We map every element with codes, tax treatment, proration, and rounding rules. We standardise names and defaults, then prove outcomes during parallel payroll so there are no surprises.
What HMRC checks are included?
We review PAYE, NI categories, pensions, and RTI readiness. We test submissions in lower environments and confirm error handling so payroll migration is audit ready.
Why is parallel payroll important?
It compares new outputs with legacy results at employee and total levels. Variances are explained and fixed before cutover, which makes sign off objective and low risk.
How long does a UK payroll system and data migration take?
Typical programmes take 8 to 14 weeks, depending on entities, data quality, and integrations. Early validation and clear acceptance criteria keep timelines realistic.
What data is migrated?
Core details, assignments, rates, allowances, deductions, pensions, and year to date balances. We confirm history needs and migrate what is required for compliance and reporting.
How do you manage proration scenarios?
We define rules for mid period joiners, leavers, and absences. We test proration during payroll data migration and prove results with variance checks in parallel payroll.
Can you coordinate with our bank and vendor?
Yes. We align submission windows, approvals, and file formats. We plan cutover timings with all parties so the switch is smooth and secure.
How are defects handled during testing?
We triage by impact and fix fast. Every fix is retested and tracked to zero. Burn down trends are reviewed with HR and Finance to keep risk visible.
What happens after go live?
Hypercare with daily reconciliations, variance dashboards, and quick fixes. We hand over a tuned runbook and a backlog of small improvements to keep gains compounding.
Do you support multi entity payroll migration?
Yes. We use a template approach with local variations. Loads and validation scale by entity while controls stay consistent.
How do you ensure data privacy?
Access is restricted by role, sensitive fields are masked in lower environments, and every action is logged. GDPR and audit needs are baked into the plan.
