Local service work
Write a clear service completion summary
A completion summary lists the work performed, what you observed while doing it, any open items with an owner, and who contacts the customer next. Keep observations apart from conclusions about causes, and avoid wording that reads as a guarantee.
Customer or job label: [ ] Visit date: [ ] Performed by: [ ] Work completed: 1. [ ] 2. [ ] Observed during the visit (what I saw or measured): - [ ] - [ ] Possible causes, labeled as unconfirmed: [ ] Pending item: [ ] Owner of pending item: [ ] Next contact, date and method: [ ] Wording I removed because it sounded like a guarantee: [ ]
Facts versus conclusions
Read each sentence and ask whether you saw it or inferred it. "The fitting was loose" is an observation. "The leak came from the fitting" is a diagnosis unless you confirmed it. Check that the completed list matches your notes and excludes work that was only discussed. Look for soft guarantees such as "should be fine now" or "won't happen again." Confirm every open item has a named owner and a next contact.
Mark every sentence in this summary as observed, inferred or promised. Flag any inferred cause written as fact and any wording that guarantees an outcome. Check that each pending item has an owner and a next contact. Suggest plainer replacements for the flagged sentences.
Finalize and file the summary
Compare the draft with your job notes and any photos you took, and correct anything beyond what you saw. Send it yourself and save a copy with the job record. For an open item, put the follow-up date where you will see it. Ask the customer to tell you if anything in the summary looks wrong.
