What to say when you're running late to a job

You are forty minutes behind. The shutoff valve on the last job sheared off in your hand, and what was supposed to be a twenty minute swap turned into a trip to the supply house. Your next customer is expecting you at two.

The temptation is to say nothing and drive faster. Almost every bad review about lateness is really a review about silence. The customer sat there not knowing, and that is the part they remember.

Tell them before they start wondering

There is a moment, usually five or ten minutes past the time you promised, when a customer stops assuming you are on your way and starts assuming you forgot. Everything you send before that moment reads as professional. Everything after it reads as an excuse.

So the timing rule is simple. The second you know you are going to be late, send the message. Not when you finish the current job. Not when you get back in the van. The moment you know.

Three messages you can copy

Change the names and the times. The structure is what matters: who you are, how late, what happens next.

Why "on my way" is the worst thing you can send

It sounds helpful. It is the message customers hate most, because it contains no information. On my way from where? Arriving when? A customer who gets "on my way" at 2:00 and is still waiting at 2:45 now believes you lied to them, even though you were genuinely driving the whole time.

Give a number or give a next checkpoint. "About 25 minutes out" is a number. "I'll know more by 3:00" is a checkpoint. Both let the customer put the phone down and get on with something else, which is the entire goal.

When you genuinely have no idea

Sometimes you are under a house with a flashlight in your teeth and you honestly cannot say whether you will be out in twenty minutes or two hours. Guessing high and being early is better than guessing low and being late again, because a second broken promise costs far more than the first one.

If you cannot even guess, promise the update instead of the arrival. Customers will accept "I will call you at 3:00 and tell you where I stand". What they will not accept is nothing.

What to say when you get there

Keep it short and do not grovel. A long apology makes the delay feel bigger than it was and invites the customer to relitigate it. One sentence, then get to work.

One more thing worth doing at the end of a day that ran long: check whether tomorrow is realistic. Late days have a habit of compounding into late weeks, and the customer you are about to disappoint is the one you booked three weeks ago and have not thought about since.

The habit underneath all of this

Every message above does the same job. It moves the customer from wondering to knowing. Most of the reputation damage from a late arrival happens in the gap between those two states, and that gap is the only part of this you fully control.
