When Payroll Is Outsourced

Most organisations send hours to somebody else. That makes the last join a contract as well as an interface.

What changes

You cannot see inside the calculation.

The format is theirs, and changes to it arrive as a notification rather than a negotiation.

The cut-off is theirs, and it is hard.

And the rule ownership question becomes a commercial one: which calculations do they perform, and which do you send already classified?

The question to ask the bureau

Ask it explicitly, in writing, and the answer is frequently not what was assumed.

Which pay rules do you apply, and which do you expect pre-calculated?

What happens if we send a figure that conflicts with a rule you apply?

Most double-counting in outsourced arrangements comes from both sides applying the same rule, each believing the other does not.

What to put in the contract

The interface specification, with notice before changes.

The cut-off, and the process for corrections after it — held, off-cycle, or re-run, with the cost of each stated.

Error correction responsibility: whose fault, whose cost, whose deadline.

Data return and deletion on termination, which matters more here because the data is on their systems.

Access for your own audit, which is easy to agree at signing and impossible afterwards.

The reconciliation

Unchanged in principle and more important in practice.

What you sent, what they received, what was paid.

Ask for the received figure, which some bureaux do not volunteer and all can provide.

Because without it, a difference between sent and paid has two possible causes and no way to distinguish them.

Where it goes wrong

A transcription step, because the bureau's format does not match your export and somebody bridges it by hand.

Corrections accumulating because the cut-off is tight and the process for late items was never agreed.

A rule change at their end applied without notice, which surfaces as an unexplained difference.

And knowledge concentrated in one person on your side who understands the format.

The check

Reconstruct three payments from your own records and the bureau's payslips.

If you cannot, you have outsourced the calculation and also the ability to explain it, which is a position worth noticing before someone disputes a payment.

Ask for the received figure

The number that makes reconciliation possible.

What you sent, what they received, what was paid.

Some bureaux do not volunteer the middle figure and all can provide it.

Without it, a difference between sent and paid has two possible causes — your export or their processing — and no way to tell which.

Ask for it as a standing report, not per incident.

Reproduce the workflow

For another way to make this requirement testable, consult time tracking for staffing agencies. Reproduce the case with real roles, codes, failures and recovery steps.

Independent reference

For a thematic point of reference, see the CIPD. Use this established source as an outside check before turning the principle into a system rule.
