Best flat-rate pricing software for small HVAC shops

Most flat-rate pricing roundups are written for the 10-truck shop with a dedicated ops person. If you’re running one or two trucks, that changes the math. A $150/mo subscription isn’t a rounding error to you, it’s a real line item, and you don’t have time to spend a weekend rebuilding a task library from scratch.

This guide compares the main flat-rate pricing options available to HVAC (and plumbing/electrical) shops on Housecall Pro, with an honest read on who each one actually fits. For a broader look at every category of pricing tool, see our full price book software comparison.

What to look for as a small shop

Before the comparison, three things matter more for a small shop than a big one:

Setup time.You don’t have staff to spend weeks customizing a task library. Either it needs to come pre-built to your margins, or someone needs to build it for you.
Cost per truck. A $150/mo tool costs a 10-truck shop $15/truck/month. It costs a 1-truck shop $150/truck/month. Same tool, very different math.
Lock-in. If you stop paying, do you still have a usable price book? Some tools leave you with nothing once the subscription lapses. Others hand you files you keep regardless.

The options

Profit Rhino

Profit Rhino, from the team behind Nexstar Network, pairs a large flat-rate task library with dispatch integrations and, for shops that want it, access to Nexstar’s broader coaching ecosystem.

Pricing: typically ~$99–179/mo, check current pricing
Best for: multi-truck shops already using or interested in Nexstar training
Watch for: the price makes more sense once you’re spreading it across a bigger team, and the default task library still needs customization to hit your specific margins

Coolfront

Coolfront is one of the longest-standing names in flat-rate pricing for trades, with a mobile app built for techs in the field and a task database covering HVAC, plumbing, and electrical. If you’re weighing these first two head to head, we compare them directly in Profit Rhino vs Coolfront.

Pricing: typically ~$99–179/mo, check current pricing
Best for: established shops that want a familiar, proven tool and don’t need a coaching layer bundled in
Watch for: some users find the interface feels older next to newer entrants, and you’re still on the hook for customizing pricing to your actual costs

The New Flat Rate (TNFR)

The New Flat Rate focuses heavily on flat-rate pricing methodology and technician-facing pricing books, with a reputation for being detail-oriented about how tasks are priced and bundled.

Pricing: typically ~$99–179/mo depending on plan and modules, check current pricing
Best for: shops that want a pricing philosophy baked into the tool, not just a task list
Watch for: the learning curve can be steeper than a simpler app, and it’s another recurring cost layered on top of your HCP subscription

Housecall Pro’s native price book add-on

HCP offers its own built-in price book functionality, which has the obvious advantage of living inside the software you already use daily. We break it down fully in our honest review of the HCP price book add-on.

Pricing: varies by HCP plan, check current pricing
Best for: shops that want the absolute simplest setup with zero third-party integration to manage
Watch for: it’s a general-purpose price book, not a flat-rate pricing engine built specifically for HVAC, so the task depth and margin logic are thinner than a dedicated tool

PriceTuneup

PriceTuneup is a different shape of product: not a subscription app, but a one-time, done-for-you rebuild of your existing HCP price book at your target margins.

Pricing: $249 one-time (the Margin-Right Rebuild)
Best for: one- and two-truck HVAC, plumbing, and electrical shops on Housecall Pro who want the pricing done correctly once, without an ongoing bill
Watch for: it’s not a full software platform with a live dashboard — it’s a rebuild plus the files and templates you need to maintain pricing yourself, with optional continuity support if you want ongoing help

Tool	Pricing	Setup	HCP Integration	Best For
Profit Rhino	~$99–179/mo	Self-service, needs customization	Direct	Multi-truck shops using Nexstar training
Coolfront	~$99–179/mo	Self-service, needs customization	Direct	Established shops wanting a known name
The New Flat Rate	~$99–179/mo	Self-service, methodology-heavy	Varies	Shops wanting a full pricing philosophy
HCP native add-on	Varies by HCP plan	Built-in, simple	Native	Shops wanting zero third-party tools
PriceTuneup	$249 one-time	Done-for-you, ~15 min import	CSV, works on every HCP plan	Small shops wanting it done once, correctly

Who each option is actually best for

If you’re a growing shop with four or more trucks and appetite for a business coaching ecosystem, Profit Rhino earns its keep. If you want a proven, established platform without extra bells on, Coolfront is a safe pick. If pricing methodology and technician-facing presentation matter most to you, The New Flat Rateis worth a look. If you just want something simple inside HCP and don’t mind a thinner task library, the native add-on removes a vendor relationship entirely.

If you’re a small shop — one or two trucks, no dedicated ops person, tired of paying $100+ a month for a tool you set up once and barely touch — PriceTuneup is built for exactly that situation. You get a rebuild at your target margins, an HVAC starter library, good/better/best presets on your top services, and clean CSVs that work on every HCP plan, for a single $249 payment instead of a recurring bill.

Frequently asked questions

What’s the real cost difference between a subscription tool and PriceTuneup?

A subscription tool at ~$99–179/mo runs $1,188–$2,148 in year one alone. The Margin-Right Rebuild is $249, one time, with optional continuity support at $299/year only if you want ongoing help after that.

Do I need an API connection to Housecall Pro for these to work?

Profit Rhino and Coolfront offer direct integrations with HCP. PriceTuneup works through CSV import/export instead, which means it works on every HCP plan with no API dependency and no risk of losing access if an integration changes.

Can I switch from Profit Rhino or Coolfront to PriceTuneup?

Yes. The rebuild works from your current HCP price book and your target margins regardless of what tool you were using before. You’re not locked into keeping a subscription running just to have a usable price book.

Is a one-time rebuild enough, or do I need ongoing software?

For most small shops, a correct one-time rebuild plus an annual price-review checklist covers the need. If you want more frequent check-ins, optional continuity is available, but it’s not required to keep using what you paid for.

How fast can I actually get a new price book live?

The import-verified CSV load into Housecall Pro is designed to take about 15 minutes once your rebuild is ready. PriceTuneup accepts 10 rebuild slots per month, so timing can depend on availability.
