Capture it when it happens
Add site photos, notes and decisions while the context is clear. A short record made on site is more useful than a long reconstruction at the end of the week.
Keep customer and commercial decisions visible
When scope changes, record what changed, why, the supporting evidence and the customer decision. This helps the business follow up before cash or trust is at risk.
Close the loop
At completion, bring together the evidence, customer update, report and sign-off status. The completed job is then ready for review follow-up and future-work proof.
Questions people ask
Do site teams need to type long notes?
No. The aim is quick, useful capture. Photos and short contextual notes are often enough.
Can this be done on a live job?
Yes. Start with one active job rather than trying to clean up every historic job at once.
