Start with the evidence
Read the agreed milestone description and gather the relevant completion or acceptance record. Do not substitute an internal calendar date for a required external confirmation.
Work through the example
A design draft was sent on Monday, but the agreement refers to customer acceptance. The sending event and acceptance event are distinct evidence, even when they occur close together.
Make the next step clear
Ask the project owner to confirm the relevant status and retain the source. Keep any billing decision with its approval rather than treating a progress label as sufficient on its own.
Keep the source context
These guides are practical organizational examples for service and project teams. They do not promise a particular time-tracking, approval or project-management feature in Eftheia. Use the tools and controls actually available to your team.
