What does finalising a pay run mean?

What changes when you finalise

Once a pay run is Finalised:

• The per-employee breakdown becomes read-only. No re-calculation, no edits.
• Year-to-date totals lock — these are what subsequent runs use as the starting point for cumulative tax calculation.
• Payslip PDFs become downloadable (admin from the run detail page; employees from their My payslips page).
• CSV export to Xero, Sage or BrightPay becomes available.
• HMRC RTI submission (coming) will only operate on finalised runs.

Why this matters

If you spot an error after finalising — wrong tax code, missing bonus, forgotten salary sacrifice — the safe path is to adjust in the next pay run rather than re-opening the finalised one. This matches how HMRC expects corrections through cumulative year-to-date adjustments.

If a finalised run was completely wrong and absolutely needs to be discarded, contact support — we can void and replace it, but it's a manual operation.

What can still happen after finalise

• Download payslip PDFs
• Export to your accounting software
• Void (only via support — has knock-on effects on year-to-date)

What can NOT happen

• Edit any employee's figures on a finalised run
• Re-calculate to pick up data changes — those will apply from the NEXT run
