Comparing payroll-provider quotations on the same basis
Compare payroll quotes using a common service brief, exception scenarios and a clear allocation of responsibilities, rather than headline fees alone.

Reviewed 17 September 2026. Recheck linked official guidance and assignment-specific requirements before relying on it.
Two payroll quotations can use the same fee label while covering different work. One may include worker queries and correction handling; another may assume that the agency prepares a complete, approved file and resolves every exception itself. Compare the service boundary before comparing the price.
The aim is a decision sheet that another colleague can follow. Keep assumptions alongside figures and ask providers to confirm gaps in writing. Do not translate an uncertain answer into an included service simply to complete the spreadsheet.
Send each provider the same brief#
Describe the proposed payroll arrangement, approximate population, pay frequencies, expected starters and leavers, locations and current systems. Explain the common exceptions in your book: late timesheets, multiple assignments, rate changes or corrections. Use redacted examples at quotation stage rather than distributing workers' personal records.
Ask for a quote tied to that brief and a stated validity period. Record which assumptions would trigger a revised quote. If the provider proposes a different arrangement, keep that as a distinct option with its responsibilities explained.
Build a comparison sheet#
| Area | Question to settle |
|---|---|
| Scope | Which entity employs, calculates, approves, pays and reports? |
| Charging unit | Is the charge per worker, payment, run, month or another unit? |
| Exceptions | How are corrections, additional runs and late inputs charged? |
| Implementation | What setup, migration and staff guidance work is included? |
| Support | Who answers agency and worker queries, and during which hours? |
| Reporting | Which reconciliation files and audit records are supplied? |
| Exit | What notice, data export and transition support apply? |
Keep VAT treatment and any minimum commitments visible as quoted. Ask the provider to explain ambiguous terms; do not assume that two totals use the same tax basis or charging unit.
Compare a normal period and an awkward one#
For an illustrative comparison, give each provider a scenario of 30 workers, one weekly run, two starters and one correction. Then ask for a second scenario with an additional run and several late adjustments. These are test inputs, not a prediction of your costs or a benchmark for the sector.
Request an itemised total for each scenario, including the agency tasks left outside the price. If one provider will not calculate a scenario, document what remains unknown and why. A lower quoted total may still require more internal preparation; describe that workload without inventing a monetary saving.
Check the operational evidence#
Ask to see a sample output, an escalation process and the proposed implementation timetable. Run through a practical question: an approved rate change is missed and a worker calls on payday. Who investigates, who authorises a correction and who keeps the worker informed?
For an employer using a payroll provider, HMRC's payroll guidance is a useful reference when defining what the process needs to cover. A service contract should make task allocation clear without implying that it removes responsibilities imposed by law.
Record the decision and its conditions#
Finish with the selected option, the reasons, unanswered questions and the conditions that must be met before implementation. Keep the quotation, assumptions and final agreement together so later invoices can be checked against what was agreed.
