Evidence and audit trail
Evidence created by the process - not reconstructed after the event.
Fortis links the data behind each worker’s pay to the calculation, the two payment routes and the reconciliation outcome. Every relevant record remains available for internal review, audit or an HMRC enquiry.
The chain
The worker-level evidence chain
Each link is written as the pay run progresses. Nothing in the chain is assembled retrospectively from separate systems.
- Assignment and agreed payment data received
- Gross-to-net payroll calculation completed
- PAYE and NIC liability identified
- RTI position recorded and reconciled
- Umbrella allocation and HMRC instruction generated
- Payment reference and authorisation recorded
- Final reconciliation completed or exception retained
