Building a Plumbing Price Book Step-by-Step: What to Actually Do Tomorrow Morning

Part 6 of an 8-part series. If you missed the earlier parts: the two functions (Part 1), the mechanical hours guide (Part 2), the margin math (Part 3), value stacking (Part 4), and bundles & SKUs (Part 5).

"How do you build your price book? Like literally, how do you do it? Not what should I do, not why should I do it, but how do you do it?"

That's how Chris Fresh opens the sixth video in the price-book series. After five videos of foundational concepts — the math, the menu, the margins, the value stacking, the bundles — this is the one that puts a hammer in your hand.

Most owners reading the price-book series so far have been nodding along and then closing the tab to figure out where to actually start tomorrow morning. This is the answer.

What a SKU Actually Is

Before you build the price book, you have to know what you're listing. Chris's definition:

"A SKU is basically an identifier, unique identifier to a service or product."

Not a category. Not a service line. A single, specific, ordered-up-by-the-customer line item. Chris's examples from the video:

• A water heater install — that's a SKU.
• A 50-gallon gas water heater installed where you supply the unit — that's a SKU.
• A 50-gallon gas water heater that you install but a different brand — that's a different SKU.
• An owner-supplied 50-gallon gas water heater installation — that's another SKU.
• An expansion tank — SKU.
• A shutoff — SKU.

If you're running a typical residential service plumbing company, you have a couple hundred SKUs. Maybe more. The natural reaction to that list is to try to perfect every single one before launching the price book. Don't.

Rule One: You Can't Do It Overnight

This is the rule that gets most owners unstuck. Chris's exact line:

"The first rule is we need to understand is we can't do it overnight."

Most price-book overhauls die in the same place: an owner sits down on a Saturday morning, opens a spreadsheet with 247 SKUs, gets two hours in, and quits. The next Saturday they don't open the spreadsheet at all. By month three the project is dead and the techs are still pricing off vibes.

The fix isn't more discipline. The fix is to stop trying to do it all at once.

Chris walks through the literal step-by-step build in this video — what to do tomorrow morning, in order:

The Step: Find the One SKU That Transacts the Most

Chris's framing: if you had 100 customers come through your business this month, how many of them bought the SAME thing?

His example from the video: maybe 20 of them were mainline drain calls. Maybe 15 were toilet fill-valve replacements. Maybe 10 were water heater installs. One of your SKUs sells more often than the rest.

That's the SKU to fix first.

Chris's exact words on the mechanics:

"I'm going to fill the jar with the biggest item first. I'm going to go find that one SKU. I'm going to build out my description. I'm going to build out my code or task code depending on which software I use and I'm going to get that thing perfect."

That's the unit of work. ONE SKU. Description. Task code. Mechanical hours (covered in Part 2). Margin-correct price (covered in Part 3). Done. Then stop and move on with your week.

The Shortcut Most Owners Don't Know About

Here's the side tip Chris drops that saves owners hours per SKU on the description side. Most owners think they have to write the SKU description from scratch.

They don't.

From Chris on the video:

"If you're doing a product like a water heater — Bradford White, Rheem, whatever it is — or you're doing a toilet, a TOTO Entrada, or TOTO Drake, you can go right to their website, steal their photo, and copy their product description. They've spent millions of dollars learning what to say to the community and to the public. Might as well just take what they have. Add your warranty to the bottom. Presto, majesto, your price book is already in motion of being built."

Bradford White, Rheem, Rinnai, A.O. Smith for water heaters. TOTO, American Standard, Kohler for toilets. Delta, Moen, Pfister for faucets. Every major manufacturer has spent millions on copy that converts homeowners. Their photos are studio-quality. Their feature lists are tested. You're allowed to use them.

So the literal Saturday-morning build looks like this:

1. Pull last 100 invoices. Find the SKU that transacts the most.
2. Open the manufacturer's product page for that item.
3. Copy the photo. Copy the product description. Paste both into your software.
4. Add your warranty language at the bottom (the part the manufacturer can't write for you).
5. Set the mechanical hours (from Part 2) and the margin-correct price (from Part 3).
6. Stop.

One SKU. Maybe 20 minutes of actual work once you stop overthinking it.

Why One SKU Fixes 20% of Your Business

This is the math that makes the "start with one" rule worth running.

Chris's framing in the video:

"If that item gets sold 20 out of a 100 times, you just fixed 20% of your invoices, 20% of your estimates, 20% of your customer experience description."

Read that again. Twenty percent of your customer experience — fixed in one Saturday-morning SKU build. Every customer who calls about that service from this week forward gets the same description, the same price, the same conversation. Your techs stop inventing the description on the truck. Your CSR stops freelancing the quote on the phone. The variability collapses.

Chris's framing for the bigger principle:

"This is how you scale quality control. Don't get lost in the details. The devil's in the details. You get lost in the bigger items. Fill the jar with the biggest items first. We can finish filling it with the small items second."

This is also why building real operational systems is what actually scales a plumbing business — not buying more trucks or hiring more techs. One SKU, perfected, fixes one fifth of your business. Three SKUs perfected fixes more than half.

Three Habits to Start Tomorrow

1. Pull your top 5 SKUs by transaction count. Open last quarter's invoices, sort by SKU, find the top five. That list is your priority queue. Most owners don't actually know what their top five are off the top of their head — and that's the first problem to solve.

2. Pick the #1 and ONLY the #1 this week. Description, task code, mechanical hours, margin-correct price. Use the manufacturer shortcut for the description if the SKU is a product. Skip everything else this week. The other SKUs will get their turn.

3. Add one new SKU per week — minimum. Don't try to do five. One. Sustainable beats heroic. By month three you've covered 60-70% of your transactions. By month six, 90%. That's how price books actually get built — slow and on purpose, not in one frantic weekend that ends in burnout.

Key Takeaways

A SKU is one specific transactable item. Water heater + brand + supply path + size = one SKU. Be specific.

You can't do it overnight. Stop trying. Owners who try to perfect everything quit. Owners who fix one SKU per week have a working price book in two months.

Find your top-transacting SKU first. Fill the jar with the biggest item. The math compounds — 20% of transactions fixed by ONE entry.

Steal the manufacturer's photo and description. Bradford White, Rheem, TOTO have spent millions on copy that converts. Use it. Add your warranty.

This is how you scale quality control. Standardized description + price + experience on the high-volume SKUs is what stops the variability your techs and CSRs are currently inventing.
