Dumb Mistakes We All Make When Managing Jobs

None of these are exotic. That is exactly why they keep costing money — they are small enough to let slide on any given day.

1. Doing variations before pricing them

"We'll sort it out later" is where margin goes to die. Later, the client remembers a different number, and you are arguing about work already built.

2. Accepting selections verbally

A tile colour agreed in a driveway conversation is not a record. Confirm it in writing the same day, even if it is one line in an email.

3. Letting progress claims run late

Claims raised a fortnight after the stage completes fund the build out of your own cash. Tie the claim to the inspection, not to when you next sit down.

4. Booking trades without confirming the predecessor

The sparky arriving before the frame is signed off is not the sparky's mistake. Confirm the stage before you confirm the trade.

5. Keeping plans in three places

If the current revision lives in your email, the site supervisor's phone and a folder in the ute, somebody is building from the wrong one. One location, revision-numbered.

6. Quoting from memory

Prices for materials move. A price list you last touched a year ago is a slow leak in every quote you send.

7. Not logging defects as you see them

A defect noticed at lock-up and remembered at handover has usually been built over. Photograph and assign it while you are standing in front of it.

8. Measuring the job only at the end

If the first time you compare actual cost to the priced budget is at final claim, you are learning things you can no longer act on. Check at each major stage instead.

The pattern

Every one of these is a record that did not get made at the moment it was cheap to make. Systems help, but the habit is what does the work: write it down where the job lives, not where you happen to be standing.
