Job Completion Checklist for Service Businesses

The last hour of a job is where many problems start. The work is mostly done, everyone is tired, and small things get skipped: a final look around, a photo, a signature, the invoice. A job completion checklist makes the ending as reliable as the middle. It also gives you a record that helps if a question comes up later. Here is what to include.

Why bother

A good ending does four things. It confirms the work is done to the agreed scope. It shows the customer what you did. It creates a record you can refer back to. And it sets up the next steps: payment, a review and perhaps a repeat booking. None of that is complicated, but all of it is easy to forget on a busy day.

Step 1: Compare the job to the scope

Take out the quote or work order and check each line against what you did. If something was changed, there should be a written change in the file; see how to write a change order. If anything agreed has not been done, finish it now or note clearly why it is outstanding and when you will return.

Step 2: Do a final walk-through

Walk the job as the customer would. Look at the work from normal viewing height and in normal light. Test what can be tested: switches, taps, doors, latches. Look for marks, dust, offcuts and anything you moved and have not put back. Use a short list so you do not rely on memory.

Step 3: Clean up and remove waste

Leave the area as you would want to find it. Remove packaging, offcuts and tools. Take away or arrange removal of waste in line with your local rules. A tidy finish is what the customer remembers.

Step 4: Take photos

Photograph the finished work from sensible angles. If you took before photos, take matching afters from the same spots. Photos help the customer see what changed and help you if a question arises later. Ask permission before taking photos inside someone's home, and do not include people or private items.

Step 5: Walk the customer through it

Show the customer the result and explain anything they need to know: how to use or care for what you installed, what to expect over the next few days, and who to call if something seems wrong. Ask if they are happy and whether anything needs attention. Listening here prevents small issues becoming complaints.

Step 6: Get a sign-off

Ask the customer to confirm the work is complete. A signature on a one-page report works well; a written "all good, thanks" by message is better than nothing. If they list items to fix, write them down with a date for when you will do them.

Step 7: Invoice and follow-up

Send the invoice the same day, with the due date and payment details; see invoice template basics. A day or so later, send a short thank-you and, if they were happy, ask for a review. Put these two steps on the same checklist so they happen without thinking.

Step 8: File the record

Save the completion report, photos, quote and any change orders in one place under the customer's name and date. If you ever need to answer a question about what was agreed or done, you can find it in a minute. Keep records as long as your local rules or your own habits suggest, and check your local rules for any required retention.

Common mistakes

• Leaving without a walk-through because you are running late.
• Taking no photos, then having nothing to show.
• Skipping the sign-off, so "was it finished?" stays a matter of opinion.
• Waiting days to send the invoice.
• Treating a customer's list of small fixes as an insult rather than a plan.
