Milestone stages
Hours per milestone
Stage sign-offs
What this means
Milestone invoicing bills specific portions of a project budget when defined deliverables or stages are completed, supported by logs of the actual work.
Software developers, builders, architects, and agencies running long-term projects billed in fixed-fee stages.
Delays in milestone sign-off block billing and cash flow
If milestone completion is vague, clients delay approvals, stalling your billing. Without a clear log of the hours and work done for that milestone, you cannot prove completion, leading to project delays and unpaid invoices.
Signs this is happening on your team
- Milestone completion is based on opinions instead of metrics
- Clients demand detailed work logs before signing off on stages
- Finance does not know when a milestone is ready to bill
- Hours logged for one milestone get mixed with the next stage
- Invoices are sent late because work verification takes days
What this costs you
Vague milestone billing slows down invoicing, ties up cash flow in unfinished stages, and creates project scope disputes with clients.
Structured milestone tracking and invoicing
TimeTracker connects project tasks and milestones in one workflow. Team members track hours against specific milestone tags. When a milestone is completed, managers verify the logs and trigger the invoice immediately.
