Plumbing Estimating Software: Top Picks for 2026 MEP Industry # Plumbing Estimating Software: Top Picks for 2026 (Image: Pelles.ai) Pelles.ai|Jun 24, 2026|Updated Nov 10, 2026|15 min (Image: Plumbing Estimating Software: Top Picks for 2026) **Plumbing estimating software turns plan quantities into a priced bid: pipe footage and fittings, fixture counts, labor units, and supplier prices.** Which tool fits depends on the work you bid. Commercial and industrial plumbing subs need takeoff plus a pipe-and-fitting database with MCAA or PHCC labor units (Trimble AutoBid Mechanical, McCormick, FastPIPE, QuoteSoft). Service and residential plumbers need a flat-rate pricebook that quotes from a phone (ServiceTitan, Housecall Pro). An AI layer such as Pelles then checks the scope against the specs and addenda before the number goes out. | # | Tool | Best for | Work | Lowest published price | Runs on | | -- | ----------------------------------------------- | -------------------------------------------------------- | ---------- | -------------------------- | ------------------ | | 1 | [Pelles](https://www.pelles.ai/preconstruction) | Scope review and proposals on top of any estimating tool | Commercial | Quote only | Web, mobile, Excel | | 2 | Trimble AutoBid Mechanical | Mechanical and plumbing estimating teams | Commercial | Quote only | Windows | | 3 | Trimble Estimation MEP Pro | Smaller MEP shops that want a browser tool | Commercial | $1,950/user/year (US) | Web (Chrome) | | 4 | McCormick Systems | A deep plumbing item and assembly library | Commercial | Quote only | Windows, hosted | | 5 | FastPIPE | Piping-heavy bids on a fixed budget | Commercial | $4,995 once, or $250/month | Windows | | 6 | QuoteSoft Pipe | Industrial piping and BIM imports | Commercial | Quote only | Windows | | 7 | STACK | Cloud takeoff, priced in your own sheets | Both | Free plan; $299/user/month | Web, field app | | 8 | Bluebeam | PDF takeoff next to an estimating database | Both | $260/user/year | Windows, web, iOS | | 9 | ServiceTitan | Mid-size and large service companies | Service | Quote only | Web, iOS, Android | | 10 | Housecall Pro | Small residential plumbing businesses | Service | $59/month | Web, iOS, Android | Prices are the vendors' own published figures, checked in November 2026\. Annual billing unless noted. ## How we chose these tools We picked tools that plumbing contractors actually bid with, then checked each vendor's own product and pricing pages in November 2026 for plumbing content, labor units, pricing feeds, and published prices. Tools that turned out not to cover plumbing were dropped: Trimble Accubid Classic is now an electrical estimating product, ConEst serves electrical and low-voltage contractors, and AI takeoff tools such as Togal.AI and Kreo don't list plumbing among their trades. We make Pelles, so it's on the list, with what it doesn't do written next to what it does. Pelles doesn't price a bid. It works alongside the estimating tools below. ## Commercial plumbing estimating vs. service plumbing quoting **Searches for "plumbing estimating software" mix two different jobs, and the tools for each barely overlap.** - **Commercial and industrial estimating** prices new construction from a plan set: hundreds of fixtures, thousands of feet of pipe, every fitting, hanger, and valve, priced against a supplier feed and labor units, then submitted to a GC. The tools are desktop or browser applications built around a takeoff screen and an item database. - **Service and residential quoting** prices a water heater swap or a drain repair on site. The plumber picks from a flat-rate pricebook, offers good-better-best options, and takes a signature and payment on a phone. The tools are field service management (FSM) platforms with a pricebook built in. The words follow the same split. A quote is a fixed price for a defined job, given on site. An estimate is the priced build-up behind a number: takeoff quantities, material prices, labor hours, overhead, and markup. A bid is that estimate submitted to a GC against a plan set, with inclusions, exclusions, and alternates. A company that does both usually runs one of each. The commercial estimating tools come first below, and the service quoting apps follow them. ## What plumbing estimating software needs to do **A commercial plumbing estimating program has four jobs, and a weak spot in any one of them shows up in the bid.** A fast takeoff priced against a stale price book still produces a bad number, and accurate prices with the wrong labor units lose the job or the margin. - **Takeoff speed.** Trace pipe runs and count fixtures from a PDF or a model. The better tools add fittings and pipe lengths as you take off a run: AutoBid Mechanical generates fittings along a traced route, FastPIPE fills the pipe between two fittings you've placed, and QuoteSoft does both. - **Material pricing.** Prices should come from a feed you can refresh before bid day, not a book last updated months ago. Vendors name Trimble's MEP pricing services and Trade Service, Ferguson Live Pricing, Harrison (CINX), Allpriser in Canada, and direct supply-house updates. - **Labor units.** Look for MCAA or PHCC units out of the box, and the ability to adjust them to [your own crews' productivity](https://www.pelles.ai/university/articles/labor-hour-estimation-productivity). National averages rarely match a local market. - **Output.** The bid should come out in the format your GCs expect, broken down by system or CSI division, without an estimator reformatting it by hand every time. That reformatting is part of [the estimating grind](https://www.pelles.ai/blog/the-estimating-grind-what-trade-contractors-deal-with-every-day) that compounds across every bid cycle. Know which of these your current process is weakest on before you book a single demo. That gap is where the right software pays back fastest. ## Best commercial plumbing estimating software The eight tools below are what commercial plumbing and mechanical subs bid with. The differences come down to how deep the pipe-and-fitting logic goes, which labor units and price feeds come with it, and what it runs on. ### 1\. Pelles [Pelles](https://www.pelles.ai/preconstruction) is an AI platform for MEP and specialty trade contractors that reads every document in a bid: drawings, specifications, addenda, and the GC's instructions to bidders. **It answers questions with a citation to the sheet or spec paragraph, compares each addendum against the bid set, and checks your takeoff against the drawings.** It works next to your estimating tool rather than replacing it, and [connects](https://www.pelles.ai/integrations) to Procore, Autodesk, Trimble, SharePoint, and Excel. **Plumbing features:** - **DoubleCheck:** Ask what the specs require for your scope, such as every pressure-reducing valve station, backflow preventer, or pipe material by system, and get each answer cited to the page. - **Compare:** Match sheets across revisions and list every change between the bid set and each addendum, so a fixture added on a riser diagram doesn't slip through. - **Reports:** Draft pre-bid RFIs, scope letters, and proposals in your own templates, with each line checked against the source documents. - **Agents:** Background jobs such as splitting and renaming every sheet in a 250-drawing set, handed back for approval. **Pricing:** Quote only, by team or company, with unlimited usage. **Watch out for:** Pelles doesn't hold labor units or a supplier price feed, so it won't price the bid. You still need one of the estimating tools below. **Best for:** Plumbing and MEP contractors with high bid volume who want fewer scope misses without adding estimators. At [Kidwell](https://www.pelles.ai/kidwell-case-study), an electrical contractor, estimators spend 70–80% less time reviewing plans and specs. ### 2\. Trimble AutoBid Mechanical Trimble AutoBid Mechanical is desktop estimating software built for commercial mechanical, piping, and plumbing contractors. It's the Trimble product to look at for plumbing; Trimble Accubid is now positioned for electrical work. **Plumbing features:** - Takeoff driven by the project specification, with fittings generated as you touch points along a pipe run. - MCAA and PHCC labor units built in. - More than 100,000 items and pre-built assemblies. - A link to Trimble's MEP pricing services for current material prices. - Spec swaps for value engineering, such as changing a system from copper to PEX and repricing it. **Pricing:** Quote only. **Watch out for:** It's a Windows desktop install with no published price, so budget time for setup and training. **Best for:** Established mechanical and plumbing subs with dedicated estimators on large commercial and institutional work. ### 3\. Trimble Estimation MEP Pro Trimble Estimation MEP Pro is Trimble's browser-based estimating and takeoff tool. Trimble describes it as built primarily for small and mid-size electrical contractors and markets it to plumbing and mechanical shops too. You can buy it online and assign licenses yourself. **Plumbing features:** - AI-powered 2D takeoff that detects scales, symbols, and length measurements. - List prices from Trade Service and Luckins, plus supplier pricing through Supplier Xchange. - Thousands of assemblies and an assembly builder. - An industry-standard set of labor units with labor factoring. **Pricing:** $1,950 per user per year in the US. Canada, the UK, and Ireland price through sales. **Watch out for:** It's electrical-first and lighter than AutoBid: Trimble publishes no plumbing database or fitting logic for it, and doesn't say whether its labor units are MCAA or PHCC. It runs in Chrome only. **Best for:** Small MEP shops, especially ones that also bid electrical, that want a browser tool without a desktop install or an implementation project. ### 4\. McCormick Systems McCormick Systems makes estimating and takeoff software for electrical, plumbing, and mechanical contractors, and is owned by Foundation Software. **Plumbing features:** - More than 40,000 plumbing items and 20,000 prebuilt assemblies, including fixtures, ProPress, CPVC, and Uponor. - Copper, PEX, PVC, CPVC, cast iron, and fixtures, with industry-standard labor units and an option to add MCAA or PHCC units. - Price updates directly from supply houses. - Integrated on-screen takeoff. **Pricing:** Quote only. **Watch out for:** McCormick markets a cloud option, but its system requirements still call for Windows 10 or 11 Pro, including for cloud clients. AI takeoff is on its published roadmap, not shipped. **Best for:** Commercial plumbing subs that want a large plumbing-specific item library and supply-house pricing. ### 5\. FastPIPE FastPIPE, from FastEST Inc., is Windows estimating software for commercial and industrial plumbing and mechanical contractors, sold alongside FastDUCT for sheet metal. **Plumbing features:** - An item catalog of more than 150,000 products from manufacturers such as Tyler, Nibco, and Viega. - AutoConnect: take off two fittings and FastPIPE adds the length of pipe between them, plus automatic riser fitting takeoff. - Ferguson Live Pricing, with Harrison and Allpriser pricing services also supported. - Export to Procore. **Pricing:** $4,995 to buy the first application (first year of maintenance included), or a $250 monthly lease that converts to ownership after 36 payments. Maintenance after year one is $1,250 a year. MCAA, PHCC, and SMACNA labor rates cost extra. There's a 60-day money-back guarantee. **Watch out for:** It's Windows-only, and union labor rates are an add-on. **Best for:** Piping-heavy mechanical and plumbing contractors who want a published price and the option to own the license. ### 6\. QuoteSoft Pipe QuoteSoft Pipe, owned by ConstructConnect, is pipe and plumbing estimating software for commercial and industrial contractors. **Plumbing features:** - Fittings generated automatically, with pipe added between fittings. - Preloaded labor, with optional MCAA and PHCC tables. - Pricing through Harrison HPH (CINX) and Allpriser. - Imports from AutoCAD and Revit models. **Pricing:** Quote only. **Watch out for:** It runs on Windows 10 or 11 Pro only, with a 16 GB RAM minimum. **Best for:** Industrial and process piping contractors who estimate from models as often as from PDFs. ### 7\. STACK STACK is a cloud takeoff and estimating tool used by subs and GCs across trades. **Plumbing features:** - Linear measurement for pipe runs, fixture counts, and Autocount for repeated symbols. - Assemblies you build yourself, with a regional BNI cost library on the Pro plan. - A STACK Field app for iOS, Android, and Windows. **Pricing:** Free plan (one active project a month, 300 plan pages, 50 measurements per project). Premium is $299 and Pro $349 per user per month, billed annually. **Watch out for:** It has no plumbing labor units or pipe-and-fitting logic, and its AI takeoff detects walls, rooms, doors, and windows rather than pipe. **Best for:** Estimators who price in their own spreadsheets and want a fast, shareable cloud takeoff. ### 8\. Bluebeam Bluebeam is PDF markup and measurement software that many plumbing estimators use for takeoff alongside a separate estimating database. **Plumbing features:** - Length, area, and count measurements on PDFs, with saved tool sets for each pipe size and fixture type. - Quantity Link (Complete plan and up) pushes measurements into Excel. - Studio Sessions to review a set with the GC or engineer. **Pricing:** Basics $260, Core $330, Complete $440, and Max $590 (introductory) per user per year. Counts start on Core. 14-day free trial. **Watch out for:** It has no labor or cost data, and Revu has no Mac desktop app. **Best for:** Estimators who already price in a database or spreadsheet and want the industry's standard PDF tool for the measuring. ## Best plumbing quoting software for service and residential work **Quoting software for plumbers is a field service app with a flat-rate pricebook, not a takeoff tool.** The plumber picks the job from the pricebook, shows the customer two or three options, and takes a signature and payment on a phone. The table compares the apps service plumbers use most; the two platforms below it are where most companies start. | App | Best for | Plumbing pricebook | Lowest published price | | ----------------- | --------------------------------------------- | ---------------------------------------------------- | ---------------------- | | ServiceTitan | Companies with several crews | Included; Pricebook Pro add-on is maintained for you | Quote only | | Housecall Pro | Owner-operators and small teams | Profit Rhino add-on, $199/month | $59/month | | Jobber | Small home-service businesses | None; quote templates and optional line items | $29/month | | FieldEdge | Plumbing, HVAC, and electrical service shops | Flat-rate pricing on every plan | Quote only | | Profit Rhino | A pricebook and sales tool on its own | Included | $39/technician/month | | The New Flat Rate | Menu pricing with five options per job | Included | $99/technician/month | | Joist | Solo plumbers who need estimates and invoices | None | $12/month | ### 9\. ServiceTitan ServiceTitan is a field service management platform for mid-size and large plumbing, HVAC, and electrical service companies. **Plumbing features:** - A pricebook in every plan, with good-better-best proposals and financing offered from a phone. - Pricebook Pro add-on: maintained plumbing content with regular updates to costs, images, descriptions, and sold hours, plus regional pricing averages. - Atlas, an AI assistant in the mobile app that reads pricebook, inventory, and estimate data. **Pricing:** Quote only, priced per technician (Starter, Essentials, and The Works plans). **Watch out for:** There's no published price and no free trial, and per-technician pricing adds up as you grow. **Best for:** Service plumbing companies with several crews that want dispatch, pricebook, and payments in one system. ### 10\. Housecall Pro Housecall Pro is a field service management app for small residential service businesses. **Plumbing features:** - A price book on every plan, and flat-rate pricing from Essentials up. - Side-by-side proposal options on Max. - The Profit Rhino price book add-on covers plumbing and drain cleaning, updated quarterly. **Pricing:** Basic $59 a month (1 user), Essentials $149 (5 users), and Max $299 (8 users), billed annually. 14-day free trial of Max, no card required. **Watch out for:** The Profit Rhino plumbing price book costs $199 a month on top of the plan, and its prices are based on US national averages. **Best for:** Owner-operators and small residential plumbing teams that want quoting, scheduling, and payments in one app. ## Other tools worth a look - **TurboBid**: Windows estimating software for small plumbing contractors, sold online at $135 a month plus a one-time setup fee, or $1,395 to buy. It has a 14-day free trial and no refunds after it, and its TurboCloud subscription syncs item, assembly, and material price updates. - **Procore Estimating** (formerly Esticom): cloud takeoff and estimating inside Procore, with AI that auto-counts repeated symbols and editable labor units. Quote only, priced by annual construction volume. - **PlanSwift**: Windows on-screen takeoff from ConstructConnect, with assemblies for pipe and fixtures but no plumbing labor or price data. Quote only, free trial. - **Jobber**: field service software for small home-service businesses, from $29 a month billed annually. Quote templates and optional line items, but no plumbing pricebook. - **FieldEdge**: service software for plumbing, HVAC, and electrical with flat-rate pricing on every plan. Quote only, no free trial. - **Profit Rhino**: a flat-rate plumbing pricebook and mobile sales tool from $39 per technician per month, with coaching and implementation required at signup. - **The New Flat Rate**: menu pricing with five prebuilt options per job, from $99 per technician per month, and it works with ServiceTitan and Housecall Pro. - **Joist**: estimates and invoices for solo contractors, with plans from $12 a month and a 14-day trial. If you bid mechanical and plumbing together, the [MEP estimating software comparison](https://www.pelles.ai/blog/top-mep-estimating-software) covers the HVAC and sheet metal side. ## Where plumbing estimates go wrong **Most plumbing bid losses come from three places: stale prices, missed scope, and no record of the assumptions.** Better software narrows each one, but none of them closes by itself. **Stale prices.** Copper and PEX press-fitting prices move between bid and buyout. A price book refreshed 60 days ago passes the old number straight into the proposal, and nothing flags it. A live supplier feed refreshed on bid day fixes most of this. **Missed scope.** Picture a six-floor hospital bid with commercial water heaters on two levels. The estimator builds the bid on a full takeoff, and three weeks later the PM finds that the pressure-reducing valve stations for the upper floors were never priced: they were in a spec section, not on the plumbing plans. Estimators covering three bids at once miss the same items: floor drain rough-ins on restaurant kitchens, tempered water mixing stations, fixtures added to a riser diagram by an addendum without a revision cloud. That's the kind of miss that [costs margin once the job starts](https://www.pelles.ai/blog/why-good-estimates-fall-apart-once-the-job-starts), and it's what a [scope sheet built from the specs](https://www.pelles.ai/university/articles/build-scope-sheet-from-specs) is for. **No audit trail.** When a GC questions a line item six weeks after bid day, you need to show which drawings, addenda, and prices it was based on. In a spreadsheet workflow, that file has usually been overwritten twice. ## How AI changes plumbing estimating **AI now helps at two points in a plumbing bid: measuring the drawings and reading the documents around them.** Neither one prices the job for you. - **AI takeoff.** Trimble Estimation MEP Pro detects scales, symbols, and length measurements on 2D drawings, and Procore Estimating auto-counts repeated symbols. Plumbing takeoff is harder than walls and rooms, so expect to check every AI count, especially pipe routing; the [AI material takeoffs guide](https://www.pelles.ai/university/articles/ai-material-takeoffs) covers where it works and where it doesn't. - **Document review.** [AI agents](https://www.pelles.ai/blog/ai-agents-for-construction-contractors) read the specs, drawings, and addenda the takeoff doesn't cover: material requirements by system, testing and disinfection, allowances, alternates, and what each addendum changed. Each answer should cite the page so the estimator can check it in seconds. - **Service quoting.** ServiceTitan's Atlas reads the pricebook and estimate data from the technician's phone, and Housecall Pro and Jobber add AI for calls and messages. The result is a reviewable draft, not a finished bid. [The estimating grind](https://www.pelles.ai/blog/the-estimating-grind-what-trade-contractors-deal-with-every-day) shifts from assembling numbers to checking them, which is where a senior estimator's time belongs. ## Pricing and total cost of ownership **The license is the visible cost. Labor units, price feeds, and the hours someone spends keeping the database current are the costs that show up later.** - **Licenses.** Published commercial prices run from $1,950 per user per year (Trimble Estimation MEP Pro) to $299 per user per month (STACK Premium). FastPIPE costs $4,995 to buy or $250 a month to lease. AutoBid Mechanical, McCormick, and QuoteSoft quote per deal. - **Labor units and pricing.** FastPIPE charges extra for MCAA, PHCC, and SMACNA rates. On the service side, the Profit Rhino pricebook adds $199 a month to Housecall Pro, and Profit Rhino's own plans require coaching and implementation at signup. - **Database upkeep.** Without a live supplier feed, your estimator spends hours every month updating prices and assemblies instead of reviewing bids. Ask each vendor which feeds are included and how often they refresh. - **Integrations.** Check exports to your accounting system and to Procore or whichever platform your GCs use. A rough way to compare: a large commercial bid that takes 40 estimator hours at $85 an hour costs $3,400 to produce. Cut that time in half and you recover $1,700 per bid, before counting a single scope miss avoided. Ask vendors for cost per bid, not just seat price. ## How to choose plumbing estimating software **Choose by the problem your estimators hit on real bids, not by the longest feature list.** Shop size is a proxy; the bottleneck is the real decision. | Your situation | Best-fit approach | | ----------------------------------------------- | ---------------------------------------------------------------------------- | | Commercial bids, 3+ estimators, union labor | AutoBid Mechanical, McCormick, or QuoteSoft, with MCAA or PHCC units | | Small commercial shop, no IT support | Trimble Estimation MEP Pro in the browser, or FastPIPE on a lease | | You price in Excel and only need fast measuring | STACK or Bluebeam | | Scope-miss change orders on recent jobs | Add an AI document layer such as Pelles to whichever estimating tool you use | | Service and residential work, several crews | ServiceTitan or FieldEdge with a flat-rate pricebook | | Owner-operator doing repairs and replacements | Housecall Pro or Jobber | Then run a trial on a real bid you've already priced, and compare the total, the hours, and what each tool caught that you missed. If you're still deciding whether to leave spreadsheets at all, [estimating software vs. Excel](https://www.pelles.ai/blog/estimating-software-vs-excel) walks through that call. ## Pair your estimating tool with a scope check The estimating tools above price what's on the takeoff. The expensive misses are the items that never made it there: a requirement in a spec section, an addendum change without a cloud, an alternate nobody priced. Pelles reads the whole bid package and flags those before the proposal goes out, with every item cited to the page. **See how Pelles handles plumbing bids: [book a demo](https://www.pelles.ai/contact).** ## Frequently asked questions ### What is plumbing estimating software? Plumbing estimating software turns the quantities on a plan set into a priced bid. It measures pipe runs and counts fixtures and fittings (the takeoff), then applies material prices from a supplier feed or price book, labor units such as MCAA or PHCC, and your overhead and markup. Commercial tools build full bids for plumbing and piping subs; service tools such as ServiceTitan and Housecall Pro quote repairs and replacements from a flat-rate pricebook on a phone. ### What is the best plumbing estimating software? For commercial plumbing, the established choices are Trimble AutoBid Mechanical, McCormick Systems, FastPIPE, and QuoteSoft Pipe, which pair takeoff with pipe-and-fitting databases and MCAA or PHCC labor units. Trimble Estimation MEP Pro is the browser-based option for smaller shops. For service and residential plumbing, ServiceTitan suits larger companies and Housecall Pro suits small ones. AI tools such as Pelles sit on top of any of them and check the bid against the specs and addenda. ### How much does plumbing estimating software cost? Published prices for commercial tools: Trimble Estimation MEP Pro is $1,950 per user per year in the US, FastPIPE is $4,995 to buy or $250 a month to lease, STACK is $299 per user per month billed annually, and Bluebeam starts at $260 per user per year. AutoBid Mechanical, McCormick, and QuoteSoft sell on quotes. TurboBid is $135 a month plus a setup fee, or $1,395 to buy. Service apps start lower: Housecall Pro from $59 a month and Jobber from $29, billed annually. ### Is there free plumbing estimating software? There's no free commercial plumbing estimating database. STACK has a free takeoff plan (one active project a month, 300 plan pages, 50 measurements per project), and most others offer trials: 14 days for Bluebeam, Housecall Pro, Jobber, and Joist, and a 60-day money-back guarantee on FastPIPE. A spreadsheet works for occasional bids, but it has no supplier price feed or labor units, so the estimator keeps both current by hand. ### What's the difference between plumbing takeoff software and estimating software? Takeoff software measures quantities from the plans: pipe footage, fixture counts, fittings. Estimating software takes those quantities and applies material costs, labor units, overhead, and markup to produce a bid. STACK, PlanSwift, and Bluebeam are takeoff tools. AutoBid Mechanical, McCormick, FastPIPE, and QuoteSoft do both in one workflow, adding fittings and pipe lengths as you take off a run, which removes the export step where quantities get lost. ### Which labor units do plumbing estimating programs use? Most commercial tools use MCAA (Mechanical Contractors Association of America) or PHCC (Plumbing-Heating-Cooling Contractors) labor units, or the vendor's own library. AutoBid Mechanical includes MCAA and PHCC units, McCormick and QuoteSoft offer them as options, and FastPIPE ships its own rates and sells MCAA, PHCC, and SMACNA rates at extra cost. Whichever you start with, adjust the units to your crews' completed jobs, since national units rarely match a local market. ### What is the best quoting software for plumbers? For service and residential plumbers, quoting software is a field service app with a flat-rate pricebook. Housecall Pro (from $59 a month) and Jobber (from $29 a month) fit owner-operators and small teams, ServiceTitan and FieldEdge fit companies with several crews, and Joist (from $12 a month) covers a solo plumber who only needs estimates and invoices. Profit Rhino and The New Flat Rate add a maintained plumbing pricebook on top. Commercial plumbers quoting from plans need estimating software instead. ### What's the difference between a plumbing quote, an estimate, and a bid? A quote is a fixed price for a defined job, usually a repair or replacement, given on site from a flat-rate pricebook. An estimate is the priced build-up behind a number: quantities from a takeoff, material prices, labor hours, overhead, and markup. A bid is the estimate submitted to a general contractor or owner against a plan set, with inclusions, exclusions, and alternates. Service plumbers mostly quote; commercial plumbing subs estimate and bid. ### Is there a plumbing estimating app for phones? Yes, for service work. ServiceTitan, Housecall Pro, Jobber, FieldEdge, and Joist all run on iOS and Android, so a plumber can build a good-better-best quote at the customer's kitchen table and take payment on the spot. Commercial plumbing estimating stays on a desktop or browser because takeoff needs a large screen, though STACK has a field app and Pelles answers questions about the plan set by phone or text. ### Can AI improve plumbing estimates? Yes, in two places. AI takeoff now ships in Trimble Estimation MEP Pro, which detects scales, symbols, and length measurements, and in Procore Estimating, which auto-counts repeated symbols. AI document tools such as Pelles read the specs, drawings, and addenda to catch scope that never made the takeoff, such as a pressure-reducing valve station called for in a spec section, and compare each addendum against the bid set. The estimator still prices and signs the bid. See what Pelles finds in your own documents Trade contractors use Pelles to surface hidden scope, catch revision changes, and automate the reading work behind every bid.
