Best Inventory Management Software for HVAC Businesses (2026)

For most HVAC contractors, QuoteIQ is the best choice because its Inventory Management feature links parts to the jobs that consume them inside a full HVAC platform, available on Elite at $299/month. ServiceTitan has deeper enterprise inventory but is quote-only and aimed at $1M+ shops. Housecall Pro includes inventory on Essentials (~$149–$189/mo) and is the easiest mid-market pick. The right answer depends on size: small shops may prefer simpler tools, while QuoteIQ’s bundle of AI estimating, scheduling, and invoicing wins on total value.

In a platform like QuoteIQ, you build a parts list with reorder thresholds, then attach parts to an estimate when you quote a job. As techs mark parts used from the mobile app, stock draws down against the live job, and used parts roll into the invoice automatically. Low-stock alerts flag items before they run out so trucks get restocked. This is fundamentally different from a standalone tracker like Sortly, which counts parts but never connects them to a job, customer, or invoice. For refrigerant, tying usage to jobs also helps with the recordkeeping the EPA’s Section 608 rules expect. See the full Inventory Management feature for details.

It depends on your size. ServiceTitan has the deeper inventory engine — serial numbers, purchase orders, warehouse-to-truck transfers — and is the better pick for HVAC companies above $1M in revenue that can staff it. But its quote-only pricing realistically runs $400–$700+/month plus implementation, per FieldCamp. QuoteIQ is better for the large majority of small and mid-size HVAC shops: inventory on Elite at $299/month, no implementation project, and a bundle that includes call answering, scheduling, and review automation.

Costs vary widely. QuoteIQ includes Inventory Management on its Elite plan at $299/month (and Max at $699/month) with no add-on fees. Housecall Pro puts inventory on Essentials at roughly $149–$189/month. FieldEdge uses quote-based per-user pricing (~$100 office + $125/tech) and often charges extra for inventory. ServiceTitan is quote-only at $400–$700+/month. Sortly offers a free tier with paid plans from $49–$149/month but isn’t an FSM. Compare full QuoteIQ pricing against your current stack — the bundled tools often offset the subscription. All figures verified May 2026.

Yes. With QuoteIQ, techs mark parts used directly from the mobile app, which draws down stock against the live job in real time — no end-of-day paperwork. That used-parts data flows into the invoice and updates the customer record automatically. Most modern platforms including Housecall Pro and ServiceTitan offer mobile inventory too, though depth varies. The advantage of a bundled tool is that the same app handles scheduling, estimating, and payments, so a tech isn’t juggling multiple logins on a roof. QuoteIQ’s Inventory Management is built for exactly this field workflow.

They’re related but distinct. Inventory Management tracks the physical parts you have in stock and on trucks — counts, thresholds, and reorder alerts. Job Costing measures profitability by comparing what a job earned against what it cost in labor and materials. They work together: inventory tells you a capacitor left the shelf, job costing tells you whether the job that used it made money. QuoteIQ includes inventory on Elite ($299) and job costing starting on Pro, so an HVAC owner can see both stock levels and margins in one system. Pair them with the AI Estimator to price jobs accurately from the start.

Most second trips happen because the right part wasn’t on the truck. When inventory is tied to scheduled jobs and estimates, a dispatcher can confirm stock before sending a tech, and low-stock alerts keep vans replenished. Eliminating even six return trips a week at roughly $70 each recovers around $21,840 a year — and that’s before counting the jobs you close on the first visit. Faster confirmation also helps capture leads: research compiled by Invoca shows a 5-minute response can be up to 100x more likely to qualify. Combined with the Virtual Call Team, QuoteIQ helps HVAC shops book and complete jobs in fewer touches.

Yes. QuoteIQ’s Inventory Management handles parts for both residential service calls and larger commercial work, and it scales with the rest of the HVAC platform — scheduling, invoicing, and reviews. Commercial HVAC tends to involve bigger equipment lists and tighter recordkeeping, which is where tying parts to jobs pays off, including for Section 608 refrigerant documentation. Very large multi-location commercial operations with serialized warranty tracking may still prefer ServiceTitan; the ACCA offers guidance on standardizing processes as you scale either way.
