HVAC Inventory & Parts Management

What to look for

• Separate the jobs: parts-on-invoice (billing) vs real stock by location (warehouse + each van) vs purchasing/replenishment—many FSMs do the first well and only some do the rest
• If you already run an FSM with a real inventory module (truck templates, transfers, POs tied to jobs), prefer that path so usage, cost, and invoice share one record
• Truck stock and van replenishment: preferred stock lists or min/max per truck, materials-used → replenishment workflows, and office visibility of what each tech is carrying
• Warehouse and multi-location transfers: receive to main stock, transfer to trucks or branch warehouses, and adjustments for shrinkage or returns
• Purchase orders and vendor part numbers linked to your pricebook/costs—confirm whether PO and inventory are base modules or paid add-ons
• Job costing of parts: auto-deduct from the correct location when a tech consumes stock, with cost hitting the job and sell price hitting the invoice
• Barcode or scan workflows for receive, pick, and truck audits (phone camera or hardware)—plus offline behavior if techs work in low-signal areas
• Serial or lot tracking for high-value equipment and warranty callbacks when that is part of your book; refrigerant usage logging is related but often a separate compliance workflow
• Standalone inventory apps (bin photos, simple counts, light barcode) when you only need a parts closet tracker and your FSM will not grow a full module—plan how (or whether) it syncs to jobs
• When FSM modules make sense: multi-truck fleets, a real warehouse, frequent stockouts, or job-cost leakage; when they may not: tiny shops that buy-from-supply-house per job and bill straight through
• Accounting sync depth varies (expense only vs true inventory asset / COGS)—verify QuickBooks or other books behavior in a live demo
• Never trust directory copy for list prices or which inventory features are included—confirm packaging, seat counts, and warehouse prerequisites with each vendor
