The short answer: your price book already exists, written across the last twenty jobs you did, so building it is extraction rather than invention and it fits in two or three evenings. Mine the recurring lines, attach honest numbers where the same task was charged three different amounts, then convert point prices into units and fold the sequences you always do together into assemblies. Speed is the advertised benefit and the third best one, because consistency and compounding matter more: a lesson banked in the book is one every future quote inherits instead of relearning it annually.
It is 9:40 on a Tuesday night and you are pricing a deck. Not your first deck. Something like your fortieth. And yet here you are at the kitchen table doing what you did for the other thirty-nine: rebuilding the number from nothing. What do joists run now? What did you charge for footings last time, and was it per footing or rolled into the frame? You scroll your sent messages looking for the quote from the Hendersons' deck last June, find it, and discover past-you priced the railing in a way present-you cannot decode.
Forty decks, and every one priced like the first one. The knowledge from the other thirty-nine is scattered across old quotes, supplier receipts, and your memory of which jobs felt bad at the end. Tonight's number will take ninety minutes, and it will still be partly a guess.
The fix has been sitting in plain sight in every established trade for decades: a price book. One list of the things you sell (items, tasks, assemblies), each with a unit and a price you have already thought hard about, once, in daylight. After that, estimating stops being invention and becomes selection. The quote that took ninety minutes takes fifteen, and the number is better.
What is a price book, exactly?
Strip the mystique: a price book is a list with three columns.
- The thing, described the way you'd say it to a client. "Supply and install interior door, hollow core, prehung." "Pressure-treated deck framing." "Toilet rebuild, tank internals."
- The unit: each, per square foot, per linear foot, per opening, per hour. Choosing the unit is half the intelligence: it is what lets one price stretch across many job sizes.
- The price. What you charge for one unit, with your labor, material, and margin already inside it, decided calmly rather than at 9:40 p.m.
Three kinds of entries fill it out. Material items (the faucet, the sheet of drywall) with your cost and your sell price. Labor tasks (demo per square foot, install per opening). And the highest-value kind, assemblies: bundles that price a whole unit of finished work as one line. "Deck framing, per square foot" contains the joists, the hangers, the screws, and the labor in one number. Assemblies are where price books stop being lists and start doing real work, because most jobs are just assemblies in different quantities.
The markup vs margin calculator converts one into the other and shows the price and profit behind both.
Build it from your last 20 jobs, not from a blank page
The paralyzing version of this project is sitting down to write "everything I sell" from scratch. Skip it. Your price book already exists. It is written across the last twenty jobs you did. The build is extraction, not invention, and it fits in two or three evenings.
Evening one: mine the quotes. Pull your last twenty quotes and invoices. List every line item that appears, and tally how often. The pattern will surprise you: the same fifteen to twenty-five items make up the bulk of everything you sell. That recurring core is your price book, version one. The exotic one-offs can stay one-offs.
Evening two: attach honest numbers. For each recurring item, look at what you actually charged across those jobs and, where you know it, what the job felt like at the end. Charged $450, $520, and $610 for the same task across three jobs? That spread is your unpriced inconsistency, and this is the moment it stops. Pick the number that reflects today's material costs and the rate you have derived from your real overhead, not the sentimental number from the job that went smoothly. Where a job lost money, the item that killed it gets priced at what it should have been, which is the whole point: the book is where lessons get banked instead of re-learned.
Evening three: unitize and bundle. Convert point prices into unit prices where the work scales (per square foot, per opening, per fixture), and fold the sequences you always do together into assemblies. Write each item's description in client-readable language while you are at it. The description will flow straight onto quotes, and "R&R subfloor sect. as req'd" is not a sentence a homeowner should meet.
Twenty-ish items, honest prices, sensible units. Resist gold-plating it: a price book at eighty percent coverage that exists beats a comprehensive one that never ships. Everything it doesn't cover, you price the old way and then add to the book, which is how it grows to fit your actual trade instead of a theoretical one.
What changes once you have one?
The speed is the advertised benefit, and it is real: the deck quote assembles from lines you already trust (framing at per-square-foot, footings each, railing per linear foot, stairs per riser) in the time it used to take to find the Hendersons' quote. Same-evening quoting, and speed wins jobs by itself.
But speed is the third-best thing the book does.
Consistency is worth more. The same work now gets the same price whether you quote it on a good Tuesday or an exhausted Friday, for a stranger or for a friend's neighbor who was hoping the friendship carried a discount you never agreed to. Clients talk to each other; your numbers now survive the comparison. And your own mood stops being a pricing input, which it has been.
The book compounds, which is worth most of all. Every job that goes sideways teaches a correction, and the correction lands in the book, where every future quote inherits it automatically. Underpriced tile demo hurts you exactly once. Without a book, that same lesson is re-learned annually, because it lives nowhere. This is the real difference between a contractor with fifteen years of experience and a contractor with one year of experience fifteen times: one of them wrote it down.
There is a quieter fourth benefit: anyone can quote. The day you add a team member, or the day you want a Tuesday off during quoting season, the book is the difference between "pricing lives in my head" and "pricing lives in the business."
The quarterly review: thirty minutes that keeps it alive
A price book is not a monument; it is a tool with a maintenance schedule. Left alone, it rots quietly: material costs drift up, your book doesn't, and suddenly every quote ships with last year's prices and this year's costs. A stale book is more dangerous than no book, because it is wrong confidently.
The discipline that prevents it is one recurring half hour, four times a year:
- Reprice the movers. You know your volatile items: lumber, copper, fuel-heavy services. Check them against current supplier pricing and bump the book, not the individual quote.
- Audit the painful jobs. Which jobs since last quarter finished worse than they were priced? Find the item or assembly that was wrong and correct it at the source.
- Promote the repeats. Anything you priced from scratch twice this quarter earns a permanent entry.
- Retire the noise. Items you haven't sold in a year get archived. A lean book gets used; a cluttered one gets bypassed.
Put it on the calendar: first Saturday of the quarter, coffee, thirty minutes. The contractors whose price books die all skipped this step; the book didn't fail, the habit did.
Where the book lives decides whether it gets used
A price book in a binder at home is out of reach at the exact moments it earns its keep: the doorstep "while you're here, what would a new vanity run?", the site visit where you could quote on the spot. A spreadsheet is better, but it still lives a copy-paste away from the actual quote, and copy-paste is where consistency leaks back out.
The working version puts the book inside the quoting tool, and this is precisely how Zeus is built: the Price Book is the center of the money side of the app. Every item carries the price you sell it at, and a supplier listing under it carries what the package costs you, so the margin is visible where the number is set. Building a quote is picking items and quantities, so the doorstep number takes two minutes and matches what everyone else was charged, and those lines carry through when the quote becomes an invoice. That same catalog is your inventory: on-hand is a ledger of what you received, used and adjusted against those same rows, so quoting and stock read from one list rather than three. At quarterly review time, you update an item once and every quote written afterward inherits the new number. It works offline in the field and syncs later, which matters on the doorsteps where signal goes to die.
Whatever you build it in, build it. The fortieth deck should not be priced like the first one. It should be priced like the fortieth, with thirty-nine jobs of banked knowledge doing the heavy lifting while you get your Tuesday evening back.
Where Zeus fits
A book in a binder at home is out of reach at 9:40 at night and out of reach on a doorstep, so the list and the quoting tool have to be the same object.
Each item you extract from the last twenty jobs goes in with its description in client language, its unit and the price you sell at, and an assembly is simply an item whose price already carries the joists, the hangers, the screws and the labor. Building a quote is picking items and setting quantities. At the quarterly half hour you reprice one row and every quote written after it inherits the number, while the ones you already sent stay exactly as the client agreed them. When somebody else quotes for you, they get their own seat and their own login and you choose what they can see, so the second person sells from the same list at the same prices. It holds on a doorstep with no signal and syncs later. That is the machinery under win the work.
The book is one part of it, and the rest of what the app does carries the job, the photos and the invoice off those same lines. Quoting and invoicing cost nothing to start; each size is listed on the pricing page. Get it on your phone and put tonight's twenty items in while they are still in front of you.
It is 9:40 and you are rebuilding the fortieth deck from nothing, scrolling for the Hendersons' quote from last June and finding a railing price that past-you left undecodable. The other thirty-nine decks already know what this one costs. They just need somewhere to say so.
Frequently asked questions
How many items should a starting price book have?
Fifteen to twenty-five, drawn from what actually recurs in your last twenty jobs. That modest core typically covers the large majority of what you quote. Under ten and you'll bypass the book too often for it to become habit; over fifty at the start and you've built a research project instead of a tool. Grow it organically. Every from-scratch price you write twice is the book telling you it wants that entry.
Should prices in the book include my markup, or do I add margin at quote time?
Bake the margin in. Book prices should be sell prices (cost plus your derived markup), so that quoting is pure selection with no arithmetic left to fumble under pressure, and so a helper quoting from the book can't accidentally sell at cost. Keep your cost recorded per item as well; the cost-to-price gap is what you'll sanity-check at the quarterly review when supplier prices move.
My jobs are all custom. Can a price book even work for me?
The jobs are custom; the components mostly aren't. A custom kitchen is still cabinet installation per box, counter templating, plumbing rough-in per fixture and electrical per opening. Those are assemblies you have done dozens of times, combined in a new arrangement. Price the recurring components in the book, price the genuinely novel remainder by hand, and notice over time how small the remainder actually is. If literally nothing recurs across your jobs, that itself is worth examining: it usually means the estimating unit is drawn too large.
Should I show clients the price book, or per-item pricing on quotes?
The book is internal: it is your pricing machinery, not a client document. On quotes, show as much line-item detail as serves the sale: larger jobs usually warrant visible sections (demo, framing, finish) so the client sees where money goes, while small jobs do better with a single clear scope price. Either way the numbers come from the book; what varies is only how much of the assembly you unfold on paper.
