How to build a flat-rate price book

A flat-rate price book is a list of every job your shop does, each with one fixed price. The tech looks up the job, sees the price, and quotes it. No math in the truck, no calling the office, no guessing in front of the customer. This guide walks through building one in eight steps.

What a flat-rate price book is

A price book is not a catalog and it is not a spreadsheet of part costs. It is a quoting tool. Each entry is a job a customer can buy: a furnace tune-up, a drain clearing, a panel upgrade. The entry has a name, a flat price, and a short note on what is included. When a tech searches for the job, the book gives the price, and the tech builds a quote from it.

Flat-rate pricing means the customer pays for the job, not the time. A capacitor replacement costs the same whether it takes twenty minutes or forty. The price is set in advance, from real costs, and it does not change on site.

Step 1: List every job you actually do

Start by writing down the jobs your shop really does, not the jobs you wish it did. Look at the last three months of invoices and write down every distinct job. A small shop will usually find 40 to 80 jobs, and about 10 of them will account for most of the work. Do not worry about the rare jobs yet. The first version of the book only needs the jobs you do every week.

Write the job names the way your techs say them. If the crew calls it a capacitor swap, write capacitor swap. The book is used on site, under pressure, and a name that only makes sense in the office will not get found.

Step 2: Group jobs into categories

Once you have the list, sort it into a handful of categories your techs already think in. For an HVAC shop, that is usually diagnostics, repairs, maintenance, and installs. For plumbing, it is drains, fixtures, leaks, and water heaters. For electrical, it is service calls, outlets and switches, lighting, and panels. Four to six categories is enough. More than that and the tech has to think about where to look, which defeats the point.

Categories also show you where the book is thin. If repairs has thirty jobs and installs has three, the missing install jobs are being priced from memory right now. Note the gaps and fill them in step 3.

Step 3: Cost each job honestly

This is the step most shops skip, and the step that decides whether the book makes money. Every job has four costs. First, the part, at the price you actually pay, not the list price. Second, the labor, at your shop rate for the time the job usually takes, including the drive there and back. Third, overhead, the share of rent, insurance, trucks, fuel, and office costs that every job has to carry. Fourth, margin, the profit that keeps the shop open and growing.

To find your overhead share, add up a month of overhead costs and divide by the number of jobs in that month. If overhead is $6,000 a month and you do 100 jobs, every job carries $60 of overhead. That number belongs in every price.

Be honest about time. Use the time the job usually takes, not the time your fastest tech takes on a good day. If a blower motor swap usually takes ninety minutes including the drive, price ninety minutes. Pricing for the best case means every normal day loses money.

Step 4: Set the flat price

Add the four numbers together and round the result to a clean number. A price of $247 looks like a calculation. A price of $245 looks like a price. Customers trust round numbers, and techs remember them. Keep the rounding small, a few dollars either way, so the math stays honest.

Write the price down and stop adjusting it on site. If the price is wrong, change the book. The price is decided before the truck leaves, when nobody is under pressure, not in a customer's kitchen.

For jobs that genuinely vary, set the price for the standard case and write the exceptions into the entry. A water heater install has one price for a standard replacement, and the entry notes what costs extra, like a new vent or a code upgrade. The tech quotes the standard price and adds the exception only when it applies, in plain sight, instead of rebuilding the price from scratch.

Step 5: Write the entry your tech will read

Each entry needs three things: a name, a price, and a short note on what is included. The note is what stops arguments: a furnace tune-up means nothing if one tech includes a filter change and another does not. Write what the price covers in one or two plain sentences.

Keep the note short. Two sentences is enough. If the note needs a paragraph, the job is probably two jobs, and it should be two entries.

Step 6: Test it with your best tech

Before you roll the book out, hand it to your best tech for a week and ask for every problem they find: missing jobs, names that do not match what the crew calls the job, and prices that are wrong for the work. Fix what they find, and ask again.

Your best tech knows the work and the customers, and will tell you the truth about whether the book helps or gets in the way. If they will not use it, nobody will.

Step 7: Train the team and roll it out

Roll the book out in a short meeting, not a memo. Show the team how to search a job, how to build a quote, and what to do when a job is not in the book. The rule for a missing job is simple: quote your best estimate, write the job down, and tell the office the same day so it gets priced and added. A book that grows from what the techs actually run gets used. A book handed down finished gets ignored.

Give the rollout a month before you judge it. The first week will feel slower, because quoting from a book is new. Watch for the tech who keeps quoting from memory, and ask why. Usually the answer is a missing job or a wrong price, and both are fixable in the book.

Step 8: Review and update every quarter

Put a quarterly review on the calendar and keep it. Part costs move, your labor rate moves, and some jobs turn out to take longer than the book assumed. Go through the book, update the prices that have moved, and tell the team what changed. A book that is current is a tool. A book that is out of date is a reason to go back to guessing.

The review is also where you find the jobs that are losing money. If a job keeps taking longer than the book allows, raise the price, split the job into two entries, or stop doing it. A price book that never changes is one nobody is watching.

What a good entry looks like

Here is one entry, finished, the way it should read in the book.

That is the whole entry. Name, price, what is included, what is not, and when to recommend it. A tech can read it in five seconds and quote it with confidence. For more finished entries, see flat-rate pricing examples.

Mistakes that sink a price book

The first mistake is pricing from the part alone and forgetting overhead, labor, and margin. The second is letting techs adjust prices on site, which turns the book into a suggestion. The third is building the whole book before anyone uses it, instead of starting with 10 jobs and adding the rest from real work. The fourth is never updating it, so the prices drift and the team stops trusting it. The fifth is writing entries only the owner understands, with part numbers instead of job names.

Every one of these is fixable, and every one of them is cheaper to fix now than after a year of quoting from memory. Start with 10 jobs, price them honestly, test with your best tech, and grow from there.

If you would rather not build the book in a spreadsheet, PriceBook, flat-rate price book software for trade shops, keeps the book searchable on a phone or tablet, so a tech can look up a price and build a quote on site. It is free for 1 price book with up to 10 items, and Pro is $49 a month for unlimited items and quote generation.
