Your HRIS integrates with payroll. Who checks that payroll is right?

Start with the field that causes the mistake

“Employee data” is too broad to be a scope. Name the fields that matter: worker ID, employing entity, pay rate, effective date, cost centre, working pattern and payroll status. Your list will differ. A connection can support one field well and require a spreadsheet for the next.

For each field, identify the authoritative system, permitted editor, receiving system and timing. Then decide what happens when the systems disagree. If neither vendor owns that answer, your payroll team will inherit it.

For each listed payroll connection, confirm the fields your purchased edition sends, what the receiving system accepts and who repairs a failed transfer.

Native, partner and file-based connections can all be sensible

File-based does not automatically mean bad. For a small workforce with predictable changes, a controlled monthly process may be proportionate. Conversely, calling a connection “real time” does not make it safe if nobody can explain whether an effective-dated change should update payroll now or later.

The right buying question is how much risk and repeat work remains in your actual process, and whether the team can manage it.

Use one field map and one named incident owner

Build a map with five entries for each critical field: where it originates, who approves it, how it travels, how receipt is checked, and who repairs a mismatch. Keep vendor responsibility distinct from your employer-side responsibility.

For a pay-rate change, that might mean HR approves the effective-dated record, the connection sends it, payroll validates the received value before its cut-off, and the internal payroll owner coordinates any incident. The supplier's contracted support responsibilities sit alongside that process. This is an illustrative allocation, not a universal division of duties.

Ask the finalist to explain one incident from detection to closure, including a third-party connection if present. Identify which supplier investigates a failed transfer and who keeps payroll informed.

Reconcile the changes, not just the employee count

A matching count can conceal a wrong value. If ten changes were sent and ten records exist in payroll, you still do not know whether the ten intended changes were applied correctly.

Define the evidence for the actual transaction: identifier, field, prior value where available, intended new value, effective date, sent status, received result and correction history. Use the minimum necessary data and your agreed access controls. Some systems will expose this differently; the requirement is that your operator can establish the outcome.

Test a valid change, an invalid code, a future-dated change, a duplicate submission and an interrupted attempt. Ask how a retry avoids creating a second change when the first attempt was accepted but its acknowledgement was lost. You do not need to demand a particular architecture to demand an understandable result.

A connector can cost less and still create more work

Assume a fictional connector saves eight hours each month against the current process. At an assumed loaded cost of $50 per hour, the annual capacity value is 8 × 12 × $50 = $4,800. If its incremental recurring cash fee is $6,000 a year, those labour assumptions alone do not justify the purchase.

That does not prove it is a bad purchase. Better controls, less re-entry or a requirement for faster updates may still justify it. Demonstrate those improvements separately from the hours-saved calculation.

Now include setup, monitoring, ongoing mapping changes and the retiring process. Avoid counting the same eight hours as both a payroll saving and an HR saving. Compare the integrated workflow with the real alternative, including any controlled manual steps that remain.

Use the complete HRIS quote model to keep software fees, one-time work and internal capacity separate.

A global HR record does not establish local payroll coverage

A product may hold an employee record for a country without calculating or filing that country's payroll. It may also connect to a local processor through a separate service. Buyers need the exact country, product and delivery model, not a broad global claim.

BambooHR's pricing page identifies its payroll add-on as being for US employees. ADP describes Workforce Now across the US and Canada, with a connection to global services for international scope. These are different product boundaries, not a verdict on which company can serve every requirement.

For a German, Japanese, Australian or New Zealand payroll purchase, obtain country-specific evidence for processing, reporting, support and handoffs. Do not infer suitability from an English-language page or a country flag in a sales deck.

Use a small acceptance packet, not a promise to test later

The complete five-case packet is below. Use fictional records in a vendor-controlled test environment, with currency and pay-period rules set by your process owner. These cases test the handoff; they do not calculate gross-to-net pay or prescribe a particular integration architecture.

For an offline worksheet, download a CSV copy of the same five cases. It is a buyer worksheet, not a file to import into payroll.

Have the process owner approve expected outcomes before the demonstration. Keep the observed result and any workaround alongside each case. Retest any workaround using the same record and compare the result with the agreed expectation.

Put the acceptance result in the project scope

1. Field coverage: the agreed mandatory fields and transformations are documented.
2. Timing: update schedules, effective dates and cut-offs match your payroll process.
3. Errors: rejected or missing changes are visible to an accountable operator.
4. Recovery: correcting and retrying the test cases produces the intended result.
5. Reconciliation: the team can establish which required changes arrived correctly.
6. Service: maintenance, incident handling, fees and escalation are agreed.
7. Change: the plan covers what happens when fields, editions or the payroll provider change.

Use representative test records and independent expected results before production. Keep any temporary manual workaround explicit, with an owner and an end condition. A supplier can reasonably need implementation to prove the final setup; your contract and project plan should reflect that dependency.
