A Simple Customer List For A Solo Plumber

You know your regulars by heart. The Hendersons with the dog. The landlord with six units who pays late more often than not. The woman on Birch Lane whose water heater you replaced a few years back.

Now picture six months from now, twice as busy. Can you still remember all of it?

A simple customer list doesn't have to be fancy. It has to exist.

What To Write Down

Keep it to what you'd want if the customer called tomorrow:

• Name and phone number
• Address, and any access notes like a gate code or a dog
• What you did, and the date
• What you quoted and what they paid
• Anything you told them to watch for
• When to check back

That's it. Six lines. If you add more, you'll stop keeping it up.

Where To Keep It

Anywhere you'll open every day. A spreadsheet works. So does a notes app, or a notebook if you're careful. The tool matters less than two rules:

• It's all in one place
• You can search it by name, address, or phone number

If you can find any customer in ten seconds, it's working.

Write Notes Future-You Can Read

"Fixed leak" tells you nothing a year later. This does:

"Replaced kitchen faucet cartridge, flushed lines, no leaks on test. Customer asked about the bathroom sink, quote sent."

The second note gives you a reason to follow up and a record if there's a question. It takes thirty extra seconds.

Add Customers The Same Day

Don't plan to catch up on Friday. You won't. Add the customer in the truck, before you drive off. It takes a minute and saves an hour of reconstructing later.

Where It Pays Off: The Slow Week

Every shop has slow weeks. The list is how you fill them.

Scan it for:

• People you quoted who never answered
• Customers you did good work for a few months ago
• Anyone you told to check back in the fall

A short, honest message goes a long way: "Hi Maria, it's Dan from Riverside Plumbing. It's been a few months since we replaced your faucet. Anything else around the house I can take a look at?" Send it only to people who'd expect to hear from you, and make it easy to say no.

Missed Calls Belong In The List

A missed call is a lead. Write down the number and the time, and what happened next. That turns a lost call into a callback and tells you how often it happens. See What To Do In The First 10 Minutes After A Missed Call.

What A Good Entry Looks Like

Here's one, written in the truck:

Maria Lopez, 14 Birch Lane. 555-0142. Gate code 4471, dog in back yard, text before arriving. Replaced 40-gallon water heater on June 3, $1,850, paid by card. Said the upstairs bath drains slowly. Quote sent June 5, no answer. Check back in September.

Count what's in there. A way to reach her, how to get in, what you did, what it cost, what she said she needed next, and when you'll follow up. You can find her in ten seconds by name or street.

In September, you open the list, see "check back," and send: "Hi Maria, it's Dan from Riverside Plumbing. I still have your quote for the upstairs bath drain. Want me to put you on the schedule?" It's a short message from someone she knows, about something she mentioned. That's how a list turns into work.

Compare that with trying to remember all this from a pile of texts and a notebook. It's why people with good lists look more organized than they are.

Keep It Private

Your list has addresses, phone numbers, and access codes. Keep it somewhere private with a password. Don't post customer details or photos of their homes without asking.

Make It Part Of Getting Paid

When you send an invoice, update the list. When it's paid, note the date. Invoicing That Gets Paid On Time covers the rest.

Start Small

Don't try to move every customer you've ever had. Start with the ones you're working for now, add the next call, and add older customers as they come back. A small, current list beats a big stale one.
