Ten platforms ranked for the workflow that actually defines window work: in-home measure, custom unit order, 3–8 week manufacturer lead time, delivery, install, warranty registration.
Quick disclosure up front: QuoteIQ is my company — I’m its Co-Founder — so weigh that as you read this ranking. My openly-biased pick is QuoteIQ ($29.99–$699/mo, flat tiers, no per-user fees), followed by Leap ($79/mo Essential, $298/mo Team, $99 per extra user), MarketSharp ($99/$199/$299 per month flat, reported), JobNimbus ($225–$550/mo base plus $20–$75 per seat plus $49–$249 texting, reported), improveit 360 (quote-only; third-party listings report entry pricing from about $125 per feature per month), Jobber ($39–$599/mo, $29 per extra user), Housecall Pro ($79/$189/$329 per month, $35 per extra user on MAX), Contractor Foreman ($49–$332/mo on prepaid yearly terms), Buildertrend (quote-only since 2026; reported $339–$1,099/mo), and ServiceTitan (quote-only; reported $245–$398 per technician per month plus $5,000–$50,000 implementation). Window installation is a custom-order, long-cycle, in-home-sales business, not a same-day service-call business, and the ranking below is ordered by how well each platform survives that specific shape of work at a small-to-mid contractor’s budget.
The honest editorial truth: most window installers sitting through a ServiceTitan or Buildertrend demo are being sold capability priced for a 20-technician HVAC company or a custom home builder, and they will pay $2,450 to $3,980 a month at ten technicians for dispatch logic that a five-truck window crew never touches.
The window install workflow has a long, quiet middle. You measure on a Tuesday, order Thursday, and nothing happens for six weeks. Then units land at the warehouse, get inspected for freight damage, get scheduled, get installed, and get registered for warranty. Software that assumes the job closes the same day it is booked will fight you at every one of those steps.
Flat pricing matters more here than in most trades because window companies carry an unusual staff ratio: canvassers, appointment setters, in-home closers, an office coordinator, a warehouse person, and install crews. Per-seat pricing taxes the exact structure the business requires. That is the structural case for my pick, and it is also the case for MarketSharp, Contractor Foreman, and Buildertrend, all of which price flat in their own way.

Start here: QuoteIQ is my company. I co-founded it in 2022 with Justin Rogers, so the number-one spot below is my openly-disclosed pick, not the output of a blind score or a neutral evaluation. Nobody handed me a scoring rubric. I put my own product first, I tell you that in the title block, the byline, this section, and the schema on this page, and then I make the case structurally so you can check my work.
The structural criteria are the same for every platform here. First, what is bundled versus sold as a paid add-on, because add-on stacking is where advertised prices stop being true. Second, pricing structure, specifically whether the platform charges per seat, because window companies carry more non-installer seats than almost any other trade. Third, fit for the actual window workflow: line-item quoting by opening, a pipeline that survives a three-to-eight-week manufacturer lead time, photo documentation of hidden conditions, and warranty registration.
Fourth, the real dollar math at five, ten, and twenty users.
Data sources: each vendor’s own published pricing page where one exists; G2, Capterra, GetApp, Software Advice, ITQlick and Tekpon for quote-only vendors, always labeled “reported”; IBISWorld for market data; EPA, ENERGY STAR, NFRC and BLS for regulatory and labor context. I do not claim to have personally run a window installation company — my 25 years are in exterior services, and on this trade I am writing from the software and operator side. All pricing verified as of July 2026, standard month-to-month rates only.
My pick, and my company — flat tiers, no per-user fees, and the quoting stack a window company actually touches every day.
I co-founded QuoteIQ in 2022 with Justin Rogers, so treat this placement as my disclosed recommendation rather than a neutral verdict. The structural argument is the pricing table: Essentials is $29.99/mo for one user, Beginner $74.99 for two, Pro $149.99 for four, Elite $299 for ten, and Max $699 for unlimited — and no tier charges per seat. For a window company running two canvassers, an appointment setter, three in-home closers, an office coordinator and two install crews, that structure is the whole argument.
On the window workflow specifically: line-item quoting handles the per-opening breakdown (frame material, window style, glass package, grids, labor) that a homeowner comparing three bids expects to see. Pipelines & Deals is the piece that matters most in this trade, because a $14,000 quote sitting in a three-to-eight-week manufacturer lead-time window is exactly the deal that falls through a service-call CRM.
MapMeasure Pro pre-scopes the home from satellite before the in-home appointment, which tells your closer whether they are walking into a 10-window or a 25-window opportunity and whether there is a siding or trim combo sale on the table. QuoteIQ Cam timestamps hidden conditions the moment the old unit comes out — rotted sills, failed flashing, sheathing damage — which is the documentation that settles change-order disputes and supports manufacturer warranty claims.
The rest of the stack is bundled rather than metered: Review Multiplier for automated Google review requests after each paid invoice, ClientHub for the customer-facing order-status thread during the lead-time gap, inventory management for tracking delivered units across warehouse and trucks, scheduling, invoicing, EmployeeHub, and business analytics. Virtual Call Team answers inbound calls around the clock on Elite and Max.
Best for: Window and door installers doing roughly $300K to $6M a year who want quoting, pipeline, install scheduling and reviews in one flat-priced system. If you run 20+ in-home closers and live and die by the one-call close presentation, Leap beats us. If you are a $15M multi-location operation, improveit 360 or ServiceTitan will fit your reporting demands better than we do.

The best in-home selling experience in home improvement — and the one platform here built around the kitchen-table close.
Leap is the platform I would put first if window installation were only about the sales appointment. Leap CRM runs the operational side — lead capture, job tracking, workflow automation, job costing, a homeowner portal, direct materials ordering from ABC Supply, SRS Distribution and QXO — and SalesPro runs the in-home presentation, with proposal building, GreenSky financing at the table, digital signature and payment capture, all fully offline. That offline capability matters in rural territories where a rep loses signal in a basement.
Pricing is where window owners need to do the math. Leap’s published pricing puts CRM Essential at $79/mo and CRM Team at $298/mo, with additional users at $99 each per month and a one-year commitment on both. SalesPro is a separate product starting around $750/mo for six users. A seven-person window shop that wants both products lands near $1,048/mo, per G2’s pricing listing and Capterra’s.
Best for: Window companies at $2M+ running a real in-home sales team where the presentation and financing close is the whole business. Leap genuinely beats QuoteIQ here — if your reps present at the kitchen table five nights a week, buy Leap.
The veteran replacement-contractor CRM — marketing attribution down to the campaign, at transparent flat rates.
MarketSharp has been the default CRM for replacement-window and remodeling companies for a long time, and its strength is the part of the business most window owners underinvest in: lead source attribution. If you spend on direct mail, canvassing, home shows and trade events, MarketSharp tracks cost per lead and cost per sale by campaign, which is the number that decides whether next season’s marketing budget is profitable.
Pricing is reported through Capterra’s listing at three flat-rate tiers: Standard $99/mo with core CRM, quoting and reporting; Pro $199/mo adding job costing and production management; Ultimate $299/mo adding advanced CRM, email automation and API access. Note the disagreement in the market — some third-party analyses describe a per-user structure in the $50 to $70 range, which at ten users would land well above the flat figures. Confirm which model you are being quoted before signing.
Best for: Established replacement-window companies spending real money on marketing who need to know which campaign produced which sale. MarketSharp beats QuoteIQ on marketing attribution depth, plainly.
Roofing-first visual pipeline boards that translate cleanly to window and siding sales crews.
JobNimbus earned its reputation in roofing, but the board-style Kanban pipeline is genuinely well suited to exterior home improvement generally, and plenty of window and door contractors run on it. It connects to CompanyCam, EagleView and HOVER, and its 2026 AI push added call answering and a voice assistant that helps shops losing leads to missed calls.
The pricing is a three-layer structure and you need all three numbers before you compare it to anything. ITQlick reports a Growing base at $225/mo and Established at $550/mo, per-user fees of $20 to $75 depending on role, and Engage texting packages from $49 to $249/mo. A solo operator lands near $349/mo; a five-person team lands near $619/mo; a ten-person team runs past $1,200/mo. Check JobNimbus pricing and the Capterra listing before you commit.
Best for: Exterior contractors already running roofing alongside windows and siding who want one visual pipeline across all three. JobNimbus beats QuoteIQ if storm-restoration and insurance-claim workflows are part of your book.
Salesforce-based enterprise CRM for large window, bath and remodeling operations with call centers.
improveit 360 is built on Salesforce and aimed squarely at large home improvement companies — the ones running 20+ in-home reps, multiple locations and a real appointment-setting call center. Coverage runs lead management, block scheduling, in-home sales presentation, contract management, financing, production scheduling and post-install service tracking, with role-based dashboards and deep custom reporting.
Pricing is quote-only. GetApp lists entry pricing from about $125 per feature per month; ITQlick reports realistic setups starting near $500/mo before implementation. Treat both as reported figures and get a written quote. Reviewers on Capterra and Software Advice also flag $125/hour billing for customization work that was previously bundled.
Best for: Multi-location window and bath remodelers running dedicated call centers and 20+ in-home reps. At that scale improveit 360 does things QuoteIQ does not attempt.
The cleanest mobile experience in field service — built for service calls, not custom-order installs.
Jobber is the best-executed small-business field service platform on this list, and I say that as a competitor. The mobile app is polished, onboarding takes an afternoon, and the quoting-to-invoice flow is genuinely frictionless. For a two-truck window repair and glass replacement outfit doing quick-turn work, it is a completely reasonable choice.
Standard month-to-month rates from Jobber’s pricing page: Core $39, Connect $119, Grow $199 for individuals; Connect Team $169 for five users, Grow Team $349 for ten, Plus $599 for fifteen. Every user beyond the plan cap is $29/mo. Add-ons are separate: AI Receptionist $99/mo, Marketing Suite $79/mo. Capterra and Tekpon both confirm the same monthly figures.
Best for: Small window repair, glass replacement and screen shops doing quick-turn work with 1–5 users. Jobber beats QuoteIQ on pure mobile polish, and I will say that every time.
Broad home-service feature coverage, with the features window companies need sold as add-ons.
Housecall Pro is a capable, mature home-service platform with strong dispatching, a solid consumer-facing booking experience and good payment tooling. The gap for window installers is the same one it has in construction generally: it was designed to send a technician to fix something today, not to manage a custom order that arrives in six weeks.
Standard month-to-month rates on Housecall Pro’s pricing page run $79 for Basic (one user), $189 for Essentials (up to five users), and $329 for MAX, with additional MAX users at $35/mo. G2’s pricing data confirms the tier structure. Add-ons stack fast: Sales Proposals around $40/mo, Vehicle GPS around $20 per vehicle per month, and the flat-rate Price Book around $149/mo.
Best for: Window and glass companies whose revenue skews toward service calls and repairs rather than full-home replacement projects.
35+ construction modules at the lowest company-wide price on this list — if you can absorb the setup.
Contractor Foreman is a construction management platform rather than a field-service tool, and for window installers doing new-construction or remodel subcontract work that distinction is in its favor. Change orders, purchase orders, submittals, AIA-format invoicing, cost codes, equipment logs and a client portal are all in the box. If your window install is one phase inside a larger project, this is the tool on the list that thinks the way you do.
Pricing per Capterra and G2: Basic $49, Standard $105, Plus $166, Pro $221, Unlimited $332 — company-wide, not per seat, with internal user caps rising by tier. Important caveat for this guide’s monthly-only rule: those figures are quoted on prepaid yearly terms and there is no true month-to-month option, so confirm the current terms before you sign. Every tier carries a 30-day free trial.
Best for: Window and door installers working as subcontractors on new construction and multi-phase remodels who need change orders and AIA invoicing. It beats QuoteIQ outright on construction project controls.
Full-remodel project management with unlimited users — now behind a volume-based quote wall.
Buildertrend is the deepest project-management platform here, with client selections, warranty management, scheduling, daily logs, estimating, takeoff, change orders and a genuinely good homeowner portal — all with unlimited users on every tier. For a window company doing full-frame replacements alongside trim, siding and interior finish work, the selections and warranty modules map neatly onto glass packages, grid patterns and manufacturer registrations.
The 2026 change matters: Buildertrend removed published pricing and moved to volume-based custom quotes tied to your annual construction volume. Reported figures from third-party analyses put Essential near $339–$499/mo, Advanced near $499–$799/mo and Complete near $829–$1,099/mo — see Costbench, this independent pricing guide, and Downtobid’s breakdown. Confirm on Buildertrend’s quote form.
Best for: Window and door companies operating as full-service remodelers on longer, multi-trade projects with heavy client-selection workflows.
The enterprise benchmark — and the wrong shape and price for almost every window installer.
ServiceTitan is a legitimately excellent platform — for a 25-technician HVAC or plumbing company with a dispatcher, a call center and a five-figure monthly ad budget. Marketing attribution, capacity planning, AI dispatching and enterprise reporting are all best-in-class. None of that is the shape of a window installation business, where the sale happens in a living room and the “dispatch” is one install crew per day against a delivery schedule.
ServiceTitan does not publish pricing. Reported figures compiled from G2, Capterra, BBB filings and contractor forums put it at $245–$398 per technician per month across Starter, Essentials and The Works, plus one-time implementation of $5,000 to $50,000 and a 12-month minimum contract — see ITQlick’s breakdown and G2’s pricing page. A ten-technician company commonly lands at $48,000–$63,000 in year-one subscription alone. Request current figures via ServiceTitan’s pricing page.
Best for: Very large multi-location exterior operations with 20+ field technicians and a dedicated admin team. Below that, the money is better spent elsewhere.

Pricing verified July 2026 from each vendor’s published pricing page where one exists, and from G2, Capterra, GetApp, Software Advice and ITQlick where a vendor quotes privately. All figures are standard month-to-month rates unless a vendor sells no month-to-month option, in which case it is stated in that platform’s card.
Run the ten-person window company through every platform here and the spread is not subtle. A shop with two canvassers, one setter, three closers, one coordinator and three installers needs ten seats. QuoteIQ Elite covers all ten at $299/mo flat, or $3,588 a year.
Housecall Pro MAX at $329 plus nine additional seats at $35 each is $644/mo before add-ons; add the Price Book at roughly $149 and Sales Proposals at roughly $40 and you are at $833/mo, or $9,996 a year. That is a $6,408 annual gap on subscription alone, and it is money that does not buy you anything a window company touches.
Jobber Grow Team at $349 for ten users plus AI Receptionist at $99 and Marketing Suite at $79 reaches $527/mo, or $6,324 a year. Leap CRM Team at $298 plus three extra seats at $99 each is $595/mo, and adding SalesPro at roughly $750 puts the full stack near $1,345/mo, or $16,140 a year. ServiceTitan at ten technicians, using the reported midpoint, runs $2,450 to $3,980 a month before implementation.
The seat math is the whole structural argument, and it is sharper in this trade than in any other I write about, because window companies carry more non-installing staff per installer than roofers, plumbers or lawn crews do. Every platform that prices per seat is charging you for the org chart the business requires.
Those are three of 4,103 reviews averaging 4.7 stars across the App Store and Google Play. I am quoting reviews of my own product, which is exactly why I am also telling you, in the card above, the six things QuoteIQ does not do well.
Write down every person who will log in: canvassers, appointment setters, in-home closers, the office coordinator, the warehouse person, crew leads and installers. Window companies routinely find they need eleven seats to support four installers. Multiply that number by each platform’s per-user fee before you look at any feature list, because that single calculation eliminates half the market. A $29 or $35 or $99 per-user charge across eleven seats is $319 to $1,089 a month that never appears on the pricing page.
During the free trial, build a fake job the way a real one runs: measure appointment Tuesday, signed contract Thursday, custom order submitted Friday, delivery expected in six weeks, install scheduled after inspection. Then ask the obvious questions. Where does the job live for those six weeks? Can the customer see order status without calling you? Does anything remind you to schedule the install when units arrive? Platforms built for same-day service calls fail this test in about four minutes.
Build an actual quote for a real house: 14 openings, mixed double-hung and casement, vinyl frames, Low-E argon glass, three with colonial grids, full-frame on four and pocket on ten, plus interior trim and haul-away. If the software forces you into a single lump-sum line item, your closer loses the ability to walk a homeowner through good-better-best at the table, and your close rate drops. Line-item quoting by opening is not a nice-to-have in this trade — it is the sales presentation.
Full-frame replacement exposes conditions nobody priced: rotted sills, failed flashing, damaged sheathing. You need timestamped photos of every one of them attached to the job file before your crew touches it, or the change-order conversation becomes your word against the homeowner’s. On pre-1978 homes, the EPA Lead RRP rule also requires documented containment and cleaning verification. Make sure the platform stores all of it in one place you can retrieve years later.
Take the base price, add per-user fees at your real seat count, add every add-on you identified in steps two through four, add payment processing at your average ticket, and add implementation if there is any. Then check the contract term and the cancellation notice period. A platform quoting $225 that arrives at $774 with seats and texting is not a $225 platform. Do this arithmetic for your three finalists on one sheet of paper, and the decision usually makes itself.
My pick is QuoteIQ, and I am its Co-Founder, so read that with the bias attached. The structural case: flat tiers from $29.99 to $699 a month with no per-user fees on any plan, line-item quoting by opening, a pipeline built to hold a deal through a three-to-eight-week manufacturer lead time, satellite pre-scoping before the in-home appointment, and photo documentation and review automation bundled rather than metered.
The honest alternatives are Leap if your business runs on in-home sales presentations, MarketSharp if marketing attribution is your bottleneck, and Contractor Foreman if you subcontract on new construction and need change orders and AIA invoicing.
Between $29.99 and roughly $4,000 a month depending on platform and headcount. Published month-to-month rates: QuoteIQ $29.99–$699 with no per-user fees; Jobber $39–$599 plus $29 per extra user; Housecall Pro $79–$329 plus $35 per extra MAX user; Leap $79–$298 plus $99 per extra user; Contractor Foreman $49–$332 company-wide on prepaid yearly terms. Reported figures for quote-only vendors: MarketSharp $99–$299 flat, JobNimbus $225–$550 base plus seats and texting, Buildertrend $339–$1,099, improveit 360 from about $125 per feature, ServiceTitan $245–$398 per technician plus $5,000–$50,000 implementation.
No, and ServiceTitan largely agrees — the company has stated its platform is not optimized for operations with three or fewer technicians. The pricing model is the disqualifier: reported rates of $245–$398 per technician per month, plus $5,000 to $50,000 in one-time implementation and a 12-month minimum contract. A window installer with four crews and five office staff pays for capability built around dispatching 25 technicians to same-day service calls.
If you are running 20+ field technicians across multiple locations with a dedicated admin team, ServiceTitan’s marketing attribution alone can justify it. Below that scale, the money buys more elsewhere. See ITQlick’s cost breakdown.
The most commonly evaluated platforms in this trade are JobNimbus, MarketSharp, Leap, improveit 360, Buildertrend, Jobber and Housecall Pro, with QuoteIQ growing quickly among small-to-mid shops. Usage splits by business model rather than by size. Companies that grew out of roofing tend to be on JobNimbus. Companies built around in-home sales teams tend to be on Leap or improveit 360. Marketing-driven replacement companies tend to be on MarketSharp. Installers who subcontract on new construction tend to be on Contractor Foreman or Buildertrend.
There is no single dominant platform in this category the way AccuLynx dominates roofing.
No platform on this list has deep order-submission integration with Andersen, Pella, Marvin or JELD-WEN, and you should be skeptical of any vendor claiming otherwise. Manufacturer-side APIs for dealer order entry are generally not public. What every platform here actually provides is a purchase-order workflow that produces a clean document you then submit through the manufacturer’s own contractor portal. The ordering step stays separate regardless of which software you buy.
What varies is how well the platform tracks the order after submission — expected delivery date, delivery confirmation, freight-damage inspection, and the trigger to schedule the install.
Export first, migrate second, run parallel third. Pull your full client list, quote history, invoice history and job notes out of Jobber as CSV before you cancel anything, because access ends when billing ends. Import clients and open quotes into the new platform, rebuild your product catalog by window type, frame material and glass package, and rebuild your quote templates. Run both systems in parallel for two to three weeks: new jobs go into the new platform, existing jobs finish in the old one.
Cancel only after the last legacy job invoices and clears. Budget two weekends of setup for a real product catalog.
QuoteIQ Essentials at $29.99 a month is the lowest entry price with no per-user fee, though Essentials covers one user — a genuine crew needs Beginner at $74.99 for two, Pro at $149.99 for four, or Elite at $299 for ten. For a larger headcount, Contractor Foreman Unlimited at $332 covers unlimited internal users on prepaid yearly terms, and Buildertrend includes unlimited users on every tier though its entry price is reported near $339.
Every platform charging per seat — Jobber at $29, Housecall Pro at $35, Leap at $99, JobNimbus at $20–$75, ServiceTitan per technician — gets more expensive exactly as you hire.

On this trade specifically, I want to be precise about what I do and do not know. I have run exterior service crews for 25 years — pressure washing, soft washing, exterior cleaning. I have not personally run a window installation company. What I bring here is the software and operator lens: I build the tools these contractors use, I read their support tickets, and I have sat with enough window and door owners to know where the seat math and the lead-time gap break a system.
Every price above is the vendor’s published standard month-to-month rate where one exists, verified between July 18 and July 25, 2026. Where a vendor quotes privately, the figure is labeled “reported” and sourced to G2, Capterra, GetApp, Software Advice or ITQlick. Industry data comes from IBISWorld, and regulatory context from the EPA, ENERGY STAR, NFRC and the Bureau of Labor Statistics. Full background, credentials and disclosures are on my About page.

Window installation punishes generic software in a specific way. The workflow is custom-order, long-cycle and sold in a living room, and the org chart carries more non-installing seats per installer than almost any other trade. Those two facts together mean the platform that wins is usually the one that prices flat and holds a deal through the lead-time gap.
My pick is QuoteIQ, and I own it — $29.99 to $699 a month, no per-user fees, quoting and pipeline and documentation and reviews in the box. If your business is the in-home sales presentation, buy Leap. If marketing attribution is your bottleneck, buy MarketSharp. If you subcontract on new construction, buy Contractor Foreman. If you are a $15M multi-location operation with a call center, look at improveit 360.
All four of those are better answers than mine for those specific shapes of business, and I would rather you buy the right tool than the one I built.
Whatever you choose, do the step-one arithmetic first. Count every seat, multiply by the per-user fee, and add the add-ons. That single number eliminates most of this list before you sit through a demo.
