The 5 Best Inventory Management Software Options for Plumbing Businesses in 2026
If your techs are constantly running back to the shop for a part that’s supposed to be on the truck, or your office finds out you’re out of stock the same moment a customer needs a repair, that’s an inventory problem software can actually fix. The best inventory management software for plumbing businesses tracks what’s on every truck and in the warehouse, flags low stock before it becomes a missed job, and ties material costs back to the job they were used on. This guide covers five tools worth considering in 2026, what each one costs, and which type of plumbing business each one fits.
Plumbing inventory is trickier than it looks on paper. You’re not just tracking one warehouse — you’re tracking parts scattered across however many trucks you run, plus whatever’s sitting on shelves back at the shop. The tools below handle that differently: some treat inventory as a core, built-in feature, others treat it as an add-on bolted onto a broader field service platform, and pricing reflects that difference significantly.
One thing worth flagging up front: a few tools on this list gate inventory management behind their higher-priced tiers, so the “starting price” you see advertised often isn’t the price you’ll actually pay to get real inventory tracking. We’ve called that out for each tool below so you’re comparing apples to apples.
Quick Comparison: Inventory Management Software for Plumbing Businesses
| Tool | Starting Price for Inventory | Best For |
|---|---|---|
| ServiceTitan | $245–$398/tech/month, plus $5,000–$50,000 implementation | Large plumbing operations that need multi-warehouse, serial-number-level tracking |
| FieldEdge | ~$100–$125/user/month, plus $39/month inventory add-on | QuickBooks-heavy plumbing shops that want inventory tied to their existing books |
| Service Fusion | $324/month (Plus plan) | Growing plumbing companies that want inventory bundled with job costing at a flat rate |
| Workiz | Custom quote (Ultimate plan only) | Plumbing shops that need van-level inventory and purchase orders inside a full FSM platform |
| QuoteIQ | $249.99/month (Elite plan, 7 users) | Small to mid-size plumbing businesses that want inventory bundled with AI tools at a flat, all-inclusive price |
The 5 Best Inventory Management Tools for Plumbing Businesses
1. ServiceTitan
ServiceTitan has the deepest inventory system of any tool on this list, and it’s built for plumbing companies running enough trucks and warehouses that manual tracking has genuinely broken down. You can add purchased items to your pricebook with vendor details, cost, and part numbers, then turn on tracking for whichever materials matter enough to monitor closely.
Pricing is quote-based, with reported figures running $245 to $398 per technician per month plus a $5,000 to $50,000 implementation fee depending on company size and setup complexity. There’s no published self-serve pricing — you go through a sales call for a custom quote, and onboarding is a multi-week process, not a same-day signup.
On the inventory side specifically, ServiceTitan manages stock across multiple warehouses and vehicles with min/max replenishment settings, so the system flags when a truck or warehouse dips below the quantity you’ve set as a safe minimum. Usage tracking via serial number and barcode scanning creates real accountability for expensive parts, and you can track material usage down to the specific job or project for accurate job costing. The Procure-to-Pay upgrade takes this further with automated, real-time updates to cost and availability, and can send purchase orders straight to suppliers without manual entry.
ServiceTitan’s inventory system also connects to a centralized purchasing workflow, so purchase orders, returns, and vendor bills across multiple warehouse locations run through one system instead of separate spreadsheets or paper trails. For a plumbing company juggling several suppliers and a warehouse plus multiple trucks, having purchasing and inventory in the same place cuts down on the double-entry that usually happens when those functions live in different tools.

ServiceTitan is best for plumbing companies with multiple trucks and at least one warehouse location that need real accountability over who’s using what parts and where. If you’re a smaller operation, the implementation fee alone will likely exceed what you’d pay for a full year with any other tool on this list.
2. FieldEdge
FieldEdge is built for HVAC, plumbing, and electrical specifically, and its inventory management sits as an add-on to the core platform rather than a separate module you’d have to bolt on from a third party. If your business already runs on QuickBooks for accounting, FieldEdge’s integration is one of its strongest selling points.
Base pricing isn’t published, but user-reported figures put it around $100 per office user per month and $125 per technician per month, with setup costs of $500 to $2,000 and roughly five weeks of onboarding. Inventory management itself runs an additional $39/month on top of the base subscription, and advanced reporting is another $49/month if you want deeper visibility into stock trends. Get a written quote before signing, since the advertised numbers rarely match the final bill once add-ons are factored in.
The inventory add-on tracks parts and materials against your pricebook, letting you tie stock levels to the same flat-rate pricing (Coolfront) that FieldEdge is known for. That means a technician quoting a job on the spot can see, in theory, whether the parts needed are actually in stock — useful for reducing the number of “we’ll have to come back next week” conversations with customers.
Because FieldEdge is built specifically for trades like plumbing, HVAC, and electrical, its inventory setup already understands concepts like flat-rate pricebooks and service agreements out of the box, rather than requiring you to build that structure yourself the way a general-purpose field service tool might. That’s a real time savings during setup if you’re already running flat-rate pricing.
Our full FieldEdge review covers Coolfront and service-agreement features in more depth.
FieldEdge is best for established plumbing companies that already lean on QuickBooks and want inventory tracking that plugs into their existing accounting workflow, rather than a standalone system they’d have to reconcile separately.
3. Service Fusion
Service Fusion bundles inventory management into its Plus plan at a flat $324/month, with unlimited users included at every tier — a real difference from tools that charge per technician or per office seat. For a plumbing company adding staff, that pricing model can end up meaningfully cheaper than per-user competitors once inventory tracking is part of the equation.
The entry-level Starter plan, at $208/month, does not include inventory management — it covers unlimited users, dispatching, invoicing, and QuickBooks integration, but you’ll need to step up to Plus for inventory. Plus, at $324/month, adds job costing, inventory management, job photos, and voice reminders. Pro, at $533/month, layers on integrated voice calling, a customer web portal, and eSign documents, but doesn’t add anything further on the inventory side.
Inventory tracking in Service Fusion ties directly into job costing, so material usage gets attributed to specific jobs automatically rather than requiring manual reconciliation at the end of the month. Combined with unlimited users, that makes Plus a reasonable landing spot for a plumbing company that wants real inventory tracking without paying per technician as the crew grows. GPS fleet tracking is a separate add-on across all tiers, running roughly $25 to $40 per vehicle per month plus hardware, worth factoring in if you want your inventory tracking paired with van location data.

Service Fusion is best for plumbing businesses planning to grow their office and field staff without wanting per-user costs to climb every time they hire, and that want inventory tracking tied directly to job costing.
4. Workiz
Workiz offers genuine van-level inventory tracking with barcode scanning, letting technicians scan parts in and out of their trucks to keep stock counts accurate without manual entry at the end of the day. That’s a real strength for plumbing crews carrying dozens of small parts across multiple vehicles.
Here’s the catch: as of Workiz’s current pricing page, inventory management is only included on the top-tier Ultimate plan, not on Standard or Pro. None of the three tiers publish a dollar figure anymore — all of them require you to request a custom quote through Workiz’s sales team. Third-party sources have previously reported figures in the $200–$350/month range for small teams, but treat those as rough estimates rather than current official pricing, since Workiz has moved to a request-a-quote model across the board.
Beyond inventory, the Ultimate plan bundles in equipment tracking, purchase orders, service plans, flat-rate pricing tools, and franchise management — features aimed at mid-size to larger plumbing operations running multiple crews or locations, not a one- or two-truck shop. All plans include core scheduling, invoicing, estimates, and online payments, with automations and reporting scaling up as you move from Standard to Pro to Ultimate.
Workiz is best for plumbing companies that have already outgrown a smaller FSM tool and specifically need van-level inventory with barcode scanning and purchase order automation. Because pricing is quote-only, get exact numbers from Workiz sales before assuming it fits your budget — there’s no way to self-serve a price estimate on their site anymore.
5. QuoteIQ
QuoteIQ takes a different approach from the rest of this list: instead of treating inventory as a paid add-on, it’s bundled directly into the Elite plan at a flat $249.99/month for 7 users, with no per-item charges or third-party integrations required. As of QuoteIQ’s February 2026 pricing update, that Elite tier also includes AI-powered tools like automated estimate generation and a virtual call team at no extra cost.
QuoteIQ runs five tiers: Essentials at $29.99/month (1 user, no inventory), Beginner at $74.99/month (2 users, no inventory), Pro at $149.99/month (4 users, no inventory), Elite at $249.99/month (7 users, inventory included), and Max at $399.99/month (unlimited users, everything included). Inventory Tracking specifically unlocks at Elite and above — if you’re on a lower tier, you won’t have access to it regardless of how many users you add.
The inventory system tracks Products, Locations, Suppliers, Orders, and Transactions as five separate modules, with real-time stock status shown as green, orange, or red indicators and reorder point alerts when something’s running low. For a plumbing business managing parts across a shop and a handful of trucks, that visual status system is a fast way to see what needs restocking without digging through a report.
QuoteIQ is best for smaller to mid-size plumbing businesses that want inventory tracking bundled with quoting, invoicing, and AI tools at one flat monthly price, without needing to budget separately for add-ons. Every plan includes a 14-day free trial, so it’s worth testing the Elite tier against a real week of parts usage before committing to annual billing.
How We Chose These Tools
We focused on inventory management features that plumbing businesses can actually access today, prioritizing tools with published pricing or reliable, current information about which plan tier unlocks inventory tracking. Several tools on this list gate inventory behind a higher-priced plan, so we specifically verified which tier includes it rather than relying on a headline “starting price” that doesn’t actually get you inventory tracking. We looked at whether inventory ties into job costing (so material costs get attributed automatically), whether tracking works across multiple trucks and warehouses, and whether the tool integrates with QuickBooks, since that’s the accounting system most plumbing businesses already run. We did not include tools without verifiable, current pricing or feature information.
Final Recommendation
For most plumbing businesses with a handful of trucks and a shop location, QuoteIQ’s Elite plan offers the best value — real inventory tracking with reorder alerts, bundled with quoting and invoicing, at a flat price with no per-technician costs. If you’re already committed to Service Fusion or want inventory tied directly to job costing without per-user fees, the Plus plan is a solid step up from Starter. Plumbing companies that already run QuickBooks heavily should look at FieldEdge, even with the inventory add-on cost, since the accounting integration will likely save more time than the extra $39/month costs. Workiz makes sense if you specifically need van-level barcode scanning and purchase orders, but get a firm quote first since pricing is no longer published. ServiceTitan only makes sense once you’re running enough trucks and warehouse locations that the implementation cost and per-tech pricing pay for themselves in reduced stockouts and better accountability — for most plumbing businesses, that’s further down the road than day one. Whichever tool you pick, test it against a real week of parts usage during the free trial before committing to annual billing.
FAQ: Inventory Management Software for Plumbing Businesses
Do I really need dedicated inventory software, or can I just use a spreadsheet?
A spreadsheet can work for a solo plumber with a small, stable set of parts, but it breaks down fast once you add a second truck or a part gets used on a job without anyone updating the sheet. Dedicated inventory software solves the update problem by tying stock counts to actual job activity — when a tech uses a part on a work order, the count updates automatically instead of relying on someone remembering to log it later.
What’s the difference between inventory management and material tracking?
Material tracking usually just logs what materials were used on a job for cost and billing purposes. Full inventory management goes further — it tracks actual stock levels across locations, flags when something needs to be reordered, and often manages purchase orders and supplier information. If a tool only offers material tracking, you can still see what got used, but you won’t get proactive alerts when you’re running low.
How much should a small plumbing business expect to pay for inventory tracking?
A small plumbing operation with 2–5 trucks can get real inventory tracking for $250 to $325/month with QuoteIQ’s Elite plan or Service Fusion’s Plus plan. Larger operations that need multi-warehouse tracking and serial-number-level accountability should expect ServiceTitan’s per-technician pricing, which is significantly higher but includes far deeper automation.
Can inventory software help me avoid running out of stock on job-critical parts?
Yes, that’s the main point of the reorder point features most of these tools include. You set a minimum quantity for a given part, and the system flags it (or in some cases automatically generates a purchase order) once stock drops below that threshold. The catch is that the system is only as good as the reorder points you set — if you set them too low, you’ll still get caught short.
Will switching to inventory software require me to count and enter my entire current stock first?
Generally, yes — you’ll need to do an initial stock count and enter it into whichever system you choose before the software can track changes accurately going forward. This is usually the most time-consuming part of getting started, especially if your current stock records are out of date. Some tools, like ServiceTitan, offer onboarding support to help with this; others expect you to handle the initial count and data entry yourself.
Should inventory tracking live in the same software as scheduling and invoicing, or as a separate tool?
For most plumbing businesses, keeping inventory in the same platform as scheduling and invoicing is worth the tradeoff, even if a dedicated standalone inventory tool has deeper features. When material usage automatically ties back to the job it was used on, job costing and billing stay accurate without manual reconciliation. A separate best-in-class inventory tool might track stock more precisely, but you’ll spend time keeping two systems in sync, which tends to be more work than it’s worth for a small or mid-size plumbing operation.
