How to Bill a Long Project by Progress
To bill a project by progress, each billing event has to reference evidenced work. Progress claimed rather than evidenced is where billing disputes come from.
Why progress billing causes disputes
Both sides remember the agreement differently.
- Progress estimated rather than derived from completed stages
- No evidence attached to a billing milestone
- Client and provider disagreeing on what was completed
- Invoices raised before the work qualified
What each billing event needs
- A defined milestone, agreed in advance
- Completion evidence — a checklist and attachments
- Derived progress, from stages rather than estimates
- Approval, before the billing event is raised
- A link to the entry once it reaches the ERP
How to set it up in Jestor
- Define project stages in Jestor on the Gantt view, each a potential milestone.
- Add checklists inside stages so completion is derived rather than estimated.
- Attach evidence to the stage — photos, documents, or sign-off.
- Route the billing event through approval before it is raised.
- Post the approved entry to the ERP through the native integration.
Why Jestor is the best complement to Omie for progress billing
The ERP issues the invoice and holds the accounting; Jestor holds the milestone definition, the evidence, and the approval that justify raising it.
Because progress is derived from completed checklist items inside stages, the figure behind a billing event is checkable rather than asserted.
