Do not promise a minute you cannot keep. Give a window, the reason for it, and a call before arrival.

What to Say When a Customer Wants an Exact Arrival Time

Give a window instead of a time, say why it is a window, and promise the one thing you can keep: a call when the tech is on the way. A customer pushing for an exact time is not being difficult; they are trying to plan a day around you, and a vague answer sounds like you are about to waste it. A specific time you then miss is worse than a window you hit, because the first late minute becomes the complaint. What settles the call is a window short enough to plan around and a heads-up they can count on.

The moment they ask for an exact time

Say

I can give you a window of eight to ten, and the tech will call you when they are on the way, so you are not waiting by the door.

Not

Sometime in the morning.

Say

The job before yours can run long, and I would rather give you a window I will keep than a time I might miss.

Not

They will be there at nine on the dot.

Say

Tell me what you have going on that day and I will see whether the first slot suits you better.

Not

We do not give exact times.

What to tell them every time

When they say a window does not work for them

Say

Would the first appointment of the day help? Nothing runs ahead of it, so it starts on time.

Not

That is just how scheduling works.

Say

If you need to step out, go. The tech will call when they are about twenty minutes away.

Not

Someone has to be home for the whole window.

Say

I will note that you need the earliest arrival in the window, and if that changes I will tell you straight away.

Not

I will try my best.

The three ways this goes wrong

Nobody minds a window they were told about and a call they can count on. What they mind is waiting on a promise nobody kept.

B

I answer the phones for contractors, and this is how I book arrival windows so the customer knows exactly what to expect. callbobai.com
