If you have gone looking for a flat rate price book, you have run into two completely different kinds of product and very little honest writing about which one you should buy.
On one side is subscription software. Profit Rhino, powered by Callahan Roach, is the best known. You pay per technician per month, you get a maintained digital price book with a mobile app, quarterly parts updates, and integration with your field service platform.
On the other side is a one-time file. You buy a spreadsheet, you own it, you edit it yourself. That is what we sell, so read the rest of this knowing that.
What follows is the actual math and an honest account of when each one is the right answer. There are real situations where the subscription is clearly correct and I will name them.
What the subscription costs
Profit Rhino publishes tiered per-user pricing. As listed on Capterra in August 2026, the Starter plan is $39 per user per month, Plus is $49, and Pro is $59. Starter includes the prebuilt price book, OEM parts search, and quarterly parts updates. Plus adds QuickBooks export. Pro adds custom option templates, invoicing, payments, and work orders.
There is also a bundled route: Housecall Pro offers Profit Rhino price books inside its own platform at $199 a month.
Software pricing changes. Check their site before you decide anything, and treat every figure in this article as accurate on the date it was written rather than permanently.
The three-year math
Per-user-per-month pricing is easy to underestimate because you evaluate it as a monthly number and pay it as a multi-year one. Here is the same decision at three sizes.
One truck, one tech
- Profit Rhino Starter: $39 per month, $468 a year, $1,404 over three years
- Tradesman Office, one trade: $99 once
Two techs
- Profit Rhino Starter: $78 per month, $936 a year, $2,808 over three years
- Tradesman Office, one trade: $99 once, the file is not licensed per seat
Three techs, multi-trade shop, on the Pro tier
- Profit Rhino Pro: $177 per month, $2,124 a year, $6,372 over three years
- Tradesman Office, all four trade books: $198 once
The gap is large enough that it is not really a price comparison. A one-truck electrician pays more for eleven weeks of the subscription than for owning our entire four-trade bundle permanently.
That does not settle the question. It reframes it. The right question is not which is cheaper, it is whether what the subscription does for you is worth several thousand dollars over three years. Sometimes it plainly is.
What the subscription genuinely buys you
Four things, and they are real.
Quarterly parts updates. Somebody else tracks OEM pricing and pushes it. If you run high-volume HVAC service where equipment parts move constantly, that is labor you are not doing. Our book expects you to update material inputs yourself a few times a year, which takes minutes but is minutes you have to actually spend.
A real mobile app. Purpose-built, designed for a technician to swipe through options in front of a homeowner on a tablet. A spreadsheet in Google Sheets on a phone works, but it is not the same experience and pretending otherwise would be dishonest.
Integration. Profit Rhino connects to Housecall Pro, FieldEdge, ServiceTitan, Service Fusion, Simpro and others. If your dispatch and invoicing already live in one of those, price book data flowing in automatically is worth money. Our books carry a service code column so you can import, but you are doing the import.
Support and onboarding. Live training, guided setup, someone to call. For a shop putting five technicians onto flat rate at once, that is a genuine implementation service and it has value.
When the subscription is the right call
Buy the subscription if most of these are true:
- You have four or more technicians in the field
- You already run a field service platform and want the price book inside it
- You need a tablet presentation experience rather than a spreadsheet
- You have office staff who will actually administer it
- Parts pricing volatility genuinely hurts you, which mostly means high-volume HVAC equipment work
At that size the per-user cost stops being the dominant factor. The cost of five technicians quoting inconsistently is larger than the subscription, and the integration saves real hours every week.
When the one-time file is the right call
Buy the file if most of these are true:
- You are one truck, or two
- You are not on field service software, or you are but you invoice out of QuickBooks and that is the whole stack
- You want to own the thing rather than rent it
- You are comfortable in Excel or Google Sheets, which for this purpose means comfortable typing a number into a cell
- Cash matters right now, which for most one-truck operations it does
The honest case here is not that our book is better software. It is not software. The case is that a one-truck electrician does not need software, needs consistent prices, and can have consistent prices for ninety-nine dollars instead of four hundred and sixty-eight a year forever.
The thing neither product will tell you
Both of these fail identically if you skip one step, and it is the step almost everybody skips.
A price book prices work against your loaded hourly rate. If you do not know your loaded hourly rate, the book will confidently generate two hundred and fifty precise, professional, internally consistent, wrong numbers. Subscription or spreadsheet makes no difference at all to this.
Your loaded rate is not your wage. It is wage plus payroll tax plus insurance plus workers comp plus vehicle plus tools plus the office plus every hour you spend driving, quoting, and chasing payment, divided across the hours you actually bill. For a lot of one-truck contractors that number turns out to be forty percent higher than what they assumed.
Work it out before you buy anything from anybody. Our Break-Even Labor Rate Calculator does it, and so does an afternoon with a legal pad and last year's tax return. The tool matters less than the fact that you did it. If you want the long version, how to calculate your true hourly rate walks through it.
The third option nobody prices
Most contractors reading this are not currently choosing between two products. They are choosing between a product and building their own, which feels free and is not.
Building a usable book from scratch runs a few weeks of evenings for a single trade. Most people quit somewhere around service number forty, when the novelty is gone and the remaining two hundred entries all need labor hours estimated honestly. The ones who finish almost always discover they left out a couple of dozen services they perform regularly, because it is genuinely hard to inventory your own work from memory.
Put an hourly value on those evenings and the do-it-yourself option is the most expensive one on the page. It is only free if your time is worth nothing, and if your time were worth nothing you would not need a price book.
What a fair comparison looks like
Set out plainly, without the marketing on either side:
- Ownership. Subscription, you rent. Stop paying and you lose access. One-time, the file is yours and stays yours.
- Per-seat cost. Subscription scales with headcount. A file does not.
- Updates. Subscription pushes them. A file needs you to do it.
- Field experience. Subscription gives you an app. A file gives you a spreadsheet.
- Integration. Subscription connects natively. A file exports and imports.
- Support. Subscription includes training and a phone number. A file includes a setup guide.
- Customization. Both are editable. A spreadsheet is more editable, because there is nothing between you and the formula.
Read that list honestly and the pattern is obvious. Everything the subscription wins on is an operational service for a business with employees. Everything the file wins on is cost and ownership. Which column matters more is a fact about your business rather than a fact about the products.
The bottom line
Four or more technicians, existing field service software, office staff to run it: the subscription earns its money, and $2,000 or more a year is a reasonable price for what it does.
One or two trucks, no platform, quoting off a phone: you are paying enterprise pricing for a problem you can solve with a spreadsheet and an hour of setup. A one-truck operator spending $468 a year on a price book is spending more annually than the whole four-trade bundle costs once.
What matters far more than either choice is that you stop quoting from memory. A contractor with any written, consistent, cost-based pricing system beats a contractor with none, by a distance that dwarfs the difference between these two products.
