HVAC Invoicing Software for Small Contractors
Invoice, schedule, and collect payment on-site in 30 seconds — built for HVAC shops with 1–5 techs, not enterprise.
Free · No credit card · Live in 7 days
Every HVAC technician knows the moment: the job is done, the homeowner is satisfied, the unit is humming — and you're standing in the driveway writing a handwritten invoice hoping the check clears by Friday. Small HVAC contractors are stuck in 1999. ServiceTitan starts at $199 per technician per month with a mandatory annual contract and a week-long onboarding session. For a solo operator running three jobs a day, that's $200 per month of overhead just to send a PDF invoice. ServiceSnap is the invoicing and scheduling software built exclusively for HVAC contractors with one to five technicians. Open the app on your phone, tap the job, fill in the part numbers, and the invoice is done. Payment is collected via Stripe before you back out of the driveway. No year-long contracts, no enterprise sales call, no dedicated IT person required. The US has more than 130,000 licensed HVAC contractors. Roughly 70 percent employ fewer than five people — that's 91,000 small businesses chronically underserved by software priced for commercial fleets and national service chains. With the residential cooling market up 34 percent in Sun Belt states since 2022 and tens of thousands of new micro-contractors entering the industry each year, the timing has never been sharper.
Why now
ServiceTitan went public at a $9B valuation in late 2024, proving the field service software market is real — yet their pricing ($199+/tech/month) has never been more disconnected from the solo contractor. The post-COVID HVAC installation boom (cooling demand up 34% in Sun Belt states) created tens of thousands of new micro-contractors who can't afford enterprise software. Stripe's Instant Payouts API now makes same-day payment collection viable for any mobile service business. Search interest in 'hvac invoicing software' grew 1,100% in the past 12 months — the demand signal is unmistakable.
Market gap
ServiceTitan and FieldEdge dominate the high end of the market (5+ tech shops with $500K+ revenue). The $20–$100K ARR small contractor is almost entirely unserved. Workiz is the closest alternative at $69/mo, but its feature set was designed for plumbing and general home services, not HVAC-specific workflows. The gap: a mobile-first HVAC invoicing app that mirrors how contractors actually work — technician shows up, diagnoses, quotes on-site, invoices before leaving, collects payment via phone — all from the van, in under 30 seconds per step.
Proof signals
5 sourced proofs ↓r/HVAC: 'ServiceTitan is overkill for a 2-man shop'
We have 2 techs. ServiceTitan quoted us $400/month plus a 3-day onboarding fee. I'm still using paper invoices and QuickBooks manually. There has to be something in between.
reddit.com ↗ReviewG2 review on Workiz: 'Not built for HVAC workflows'
Workiz is designed for plumbing and general home services. The HVAC-specific flows — refrigerant tracking, equipment serial numbers, maintenance agreements — just aren't there.

Built this after watching my uncle's HVAC shop lose 15% of invoices to manual filing errors. MVP in 6 weeks, 40 paying users from a single r/HVAC post.

acca.com ↗Complaintr/smallbusiness: 'FieldEdge pricing is insane for solo techs'
FieldEdge wants $150/month per technician. I'm one guy with a van. I just need to invoice people and schedule service calls. Why is this so hard to find at under $50/month?

Pricing thesis · subscription
Monthly flat fee removes the per-technician pricing model that makes ServiceTitan unaffordable for small shops. Flat pricing aligns with how small contractors think about software costs.
Benchmarks. ServiceTitan: $199+/tech/mo (annual), FieldEdge: $99-149/tech/mo, Workiz: $69-225/mo flat, FieldPulse: $59/mo solo, Jobber: $69-249/mo
