Best Inventory Management Software for Plumbing & HVAC Companies in 2026
For plumbing and HVAC contractors, inventory lives in two places: the warehouse and the service van. Getting the van stock right is as important as the warehouse — a tech who shows up to an emergency without the right part loses the call, the customer's trust, and a same-day job. Software that tracks van inventory, triggers warehouse replenishment, and links parts usage to work orders closes the loop between what was used in the field and what needs to be restocked. Here are the platforms that handle field service inventory correctly.

ServiceTitan
Enterprise field service management platform with comprehensive inventory management for warehouse and truck stock.
Why it fits this industry
ServiceTitan's inventory module tracks both warehouse stock and individual technician van inventory. When a tech closes a job and uses parts, inventory is automatically decremented. Low-stock alerts trigger purchase orders, and the system tracks inventory value for accounting. For companies over $3M in revenue, it's the gold standard.
Pros
- ✓Truck-level inventory tracking per technician
- ✓Automatic inventory depletion from completed jobs
- ✓Purchase order management with vendor integrations
- ✓Inventory value tied to financial reporting
Cons
- ✕Expensive — significant implementation and monthly cost
- ✕Feature depth creates a steep learning curve
- ✕Smaller companies may not need this level of complexity
Pricing: Contact for pricing (typically $400-$600+/month)
Best for established plumbing and HVAC companies scaling past $3M revenue that need enterprise-grade inventory tied to dispatch, job costing, and financials.
Housecall Pro
Field service management platform for small to mid-size trades businesses with parts and materials tracking.
Why it fits this industry
Housecall Pro lets technicians add materials to jobs from the field, tracks parts usage per work order, and provides a price book for consistent materials pricing. It's more accessible than ServiceTitan for smaller shops that need real parts tracking without the enterprise investment.
Pros
- ✓Technician can add parts to jobs from mobile in the field
- ✓Price book with materials and labor pricing
- ✓Simple interface with fast tech adoption
- ✓Affordable for small and growing companies
Cons
- ✕Warehouse inventory management is limited compared to ServiceTitan
- ✕No truck-stock tracking per vehicle
- ✕Advanced inventory reporting requires manual work
Pricing: Starts at $79/month
Best for small to mid-size plumbing and HVAC shops that need clean field materials tracking without a full warehouse inventory system.
simPRO
Trade business management platform built for plumbing, HVAC, and electrical contractors with multi-location inventory.
Why it fits this industry
simPRO was built specifically for trade contractors and includes one of the most complete inventory systems in the category — warehouse management, job site inventory, purchase orders, supplier catalog integration, and stock transfers between locations. It handles both service and project-based work.
Pros
- ✓Trade-specific inventory with warehouse and job site tracking
- ✓Purchase orders integrated with supplier catalogs
- ✓Handles both service work and large project inventory
- ✓Multi-warehouse and stock transfer support
Cons
- ✕Complex to implement — requires dedicated setup time

Best for plumbing and HVAC contractors who need full-featured trade-specific inventory management across warehouses, vehicles, and job sites.
FieldEdge
HVAC and plumbing-specific service management software with inventory and QuickBooks integration.
Why it fits this industry
FieldEdge is purpose-built for HVAC and plumbing contractors and integrates directly with QuickBooks for accounting. Its inventory module tracks parts in the warehouse and on service trucks, with job costing that flows into QuickBooks without duplicate entry.
Pros
- ✓Built specifically for HVAC and plumbing workflows

- ✓Flat-rate price book and parts pricing built in

Best for HVAC and plumbing service companies that use QuickBooks and want a trade-specific platform that eliminates duplicate data entry.
Jobber
Field service management software for small trade businesses with quoting, scheduling, and materials tracking.
Why it fits this industry
Jobber's simplicity makes it the go-to for plumbing and HVAC startups and small operators. Technicians can add line items for parts to jobs, and the quote-to-invoice workflow is straightforward. It won't replace a warehouse management system, but for shops under 10 technicians, it handles daily parts tracking reliably.
Pros
- ✓Very easy to set up and use — field crews adopt it quickly
- ✓Clean mobile experience for technicians
- ✓Affordable pricing for small companies
- ✓Strong quoting and invoicing flow
Cons
- ✕No dedicated warehouse or van-level inventory tracking
- ✕Parts are added as line items rather than tracked as stock
- ✕Outgrown quickly as companies scale past 10 techs
Pricing: Starts at $49/month
Best for plumbing and HVAC startups and companies under 10 technicians that need clean job management with basic materials tracking.
Buyer's Guide
Plumbing and HVAC inventory management has a unique challenge: inventory is mobile. Unlike a retail store, your stock is spread across a warehouse, multiple service vans, and sometimes active job sites. Software must account for all three. The most important question to answer before buying is whether you need true warehouse inventory with perpetual counts and purchase order automation, or whether you primarily need to track parts added to work orders. Small shops (under 10 techs) often start with Jobber or Housecall Pro for work-order-level tracking; companies with warehouses and fleets of 10+ techs need simPRO, ServiceTitan, or FieldEdge. Also consider your accounting software — if you're on QuickBooks, FieldEdge's deep integration saves significant time.
