Claim vs certification
Keep the submitted claim and certified result as distinct, attributable facts.
RA control design
Design an RA bill trail from claim to net payable
The current release records bills, deductions, approvals and payment evidence. Measurement books and an attributable claim-versus-certification workflow remain planned; the controls below are design requirements.
Where control breaks
Recognise the warning signs
- Claims are overwritten during certification
- Cumulative values are hand-entered
- Deductions lack a clear basis
The CostGrid control path
Server totals
Calculate previous and cumulative certified values from posted records, not browser inputs.
Explicit net payable
Show retention, advance recovery, withholding, deductions and approved additions separately.
Operational outcome
Use this checklist to evaluate the future certification workflow; do not treat it as a current feature claim.
Control one live project before expanding
Start with one live project, keep the control trail intact, and expand only after the workflow proves useful.
