Flat rate software: what it does, what it costs, and who actually needs it
Flat rate software promises one thing: your techs quote a fixed, profitable price before the work starts, in any trade — HVAC, plumbing, electrical, appliance repair. The subscriptions that sell this run $129+/month to $179+/monthat published list prices, and for some shops they’re worth every dollar. For a lot of small shops, though, the expensive part of flat-rate pricing was never the software — it’s knowing whether the prices in your book actually clear your margin.
This page covers what the software really does, the published prices as of July 2026, and the cheaper routes when you don’t need the whole engine. If you’re new to the pricing model itself, start with what flat rate pricing is and come back.
What flat rate software actually sells you
Every flat-rate engine bundles three things, and it helps to price them separately in your head:
A task catalog.Thousands of pre-built repair tasks with hours and suggested prices, maintained by the vendor as parts costs move. This is the piece you’re mostly renting.
The pricing math.Your labor rate, parts markup, and target margin applied across the catalog. The math isn’t secret — it’s the same formula a free calculator runs — but the software applies it book-wide.
A presentation app. The tablet screen showing the customer good/better/best options at a fixed price. This is the piece multi-truck shops genuinely lean on daily.
The catch every vendor shares: the catalog still has to be customized to your labor rate and margins before it prices jobs correctly, and the subscription keeps billing long after that setup work is done.
The main options and their published prices

Shops with a book whose prices need fixing, not renting
The vendors market hardest to HVAC, but the flat-rate model is identical in every trade — only the task list changes. If you’re starting from zero in your trade, a free starter book beats a subscription trial: we publish import-ready flat-rate templates for HVAC, plumbing, and electrical, plus appliance repair, garage door, and handyman — all linked from the flat rate price book template page. Each ships as a CSV with structured, priced tasks you adjust to your own rates.
For the trade-specific pricing math — labor rates, parts markup tiers, what a defensible price looks like — the guides on plumbing flat rate pricing and HVAC flat rate pricing walk through it number by number.
When you don’t need the subscription
Here’s the case the vendors won’t make: if you already have a service list in Housecall Pro or another platform, you don’t have a catalog problem. You have a pricing problem — prices set years ago, costs that drifted, nobody checking margins. A rented catalog doesn’t fix that; it replaces your book with the vendor’s and hands you the same customization work plus a monthly bill.
That audit is what an unwatched book looks like from the inside — services priced below cost with nobody noticing. The Margin-Right Rebuild fixes exactly that: your existing price book, every price recalculated at your target margin, delivered as import-verified CSVs for $249 one time. You keep the files. Optional continuity software is $299/yr ($199/yr founding) only if you want ongoing help.
The 60-Day Ticket-Lift Guarantee
If your average ticket doesn't go up within 60 days of importing your new price book, we refund the full price — and you keep every file.
Frequently asked questions
What is flat rate software?
Flat rate software packages the three pieces of flat-rate pricing into one product: a task catalog with preset prices, the math that keeps those prices at your labor rate and margins, and a mobile app for presenting fixed prices to the customer before work starts. Vendors like Profit Rhino, Coolfront, and The New Flat Rate sell it as a subscription; the alternative is building or rebuilding your own price book and running it inside the field service platform you already pay for.
How much does flat rate software cost?
Published list prices as of July 2026: Profit Rhino runs $179+/month, Coolfront $129+/month, The New Flat Rate $99/tech/month, and Housecall Pro's price book add-on $149/month. Most vendors finalize the number on a sales call based on plan and tech count, so treat these as floors. The main non-subscription route is a one-time price book rebuild at $249.
What is the best flat rate software for a small shop?
For a one- to three-truck shop, the honest answer is often none of the subscriptions — the catalog gets customized once and the bill keeps arriving. If your techs present good/better/best options in the field daily, The New Flat Rate ($99/tech/month) or Profit Rhino ($179+/month) earn their keep. If the real problem is that your existing prices don't clear margin, a $249 one-time rebuild of your own book fixes that without rent.
Is there free flat rate software?
There's no free full flat-rate engine, but the pieces exist free: per-trade starter price book templates with priced tasks, a flat-rate price calculator for the per-job math, and a margin leak finder that checks an existing book against your target margin. For a small shop, those pieces plus the price book inside your field service platform cover most of what the subscriptions do.
Does flat rate software work for plumbing and electrical, or just HVAC?
Flat-rate pricing is trade-agnostic and the major vendors all sell plumbing and electrical catalogs alongside HVAC. The math is identical in every trade — loaded labor cost times task hours, plus marked-up parts, priced to your target margin. What changes by trade is the task list itself, which is why starter templates and pricing guides are built per trade.
Check your book before you rent anyone’s catalog
Run your price book export through the free Margin Leak Finder — it works entirely in your browser and shows which services are priced below your target margin. If the leaks are real, the Margin-Right Rebuild fixes the whole book for $249, one time, backed by the 60-Day Ticket-Lift Guarantee. We open 10 rebuild slots a month.
