Custom software for a window and door installer runs $50,000 to $350,000, and the decision that moves the number most is whether the system has to pull live order status out of your manufacturers. Accepting that someone types the Pella or Andersen confirmation date into the system keeps you at the bottom of the range and still gets you most of the scheduling benefit. Wiring an actual integration so a slipped frame reschedules the crew before the truck is loaded is where real weeks go, because manufacturer systems differ from each other and none of them were designed for your convenience.
The bands a window and door build falls into
Two tiers, and which one you need depends on whether you are plugging specific leaks or replacing how the company runs.
A focused first release runs $50,000 to $120,000 and ships in 10 to 16 weeks. For most window companies that means one or two of the revenue leaks done properly and wired into what you already use: the after hours phone agent that turns a 9pm call into a booked measure, automated follow up on open estimates, and a per opening quote that an estimator can build at the kitchen table instead of in a spreadsheet tab that evening.
A full operations platform runs $150,000 to $350,000 phased across 6 to 12 months. That covers quoting through to supplier orders, dispatch that understands install durations, review automation and mining a decade of quote and win loss history.
You can spend less than $50,000, but only on one narrow thing. What you cannot buy at that price is a platform, and a quote that promises quoting, dispatch, supplier tracking and a phone agent for the price of a single crew truck is a scheduler with your logo on it. You already own a scheduler.
What drives a window and door build up
Supplier integration first. Getting order and delivery status out of a manufacturer system, or exchanging documents electronically with one, is genuine engineering, and each manufacturer is its own piece of work. It is also where the value sits, because a delayed frame nobody caught is a wasted crew day and an unhappy homeowner waiting at home.
Quote configuration second. A window quote is not one price. It is frame material, glass package, grid pattern, exterior and interior colour, and install type, per opening, across nine or fourteen openings, with egress and structural constraints that change the answer. Encoding that so an estimator or an automated assistant can build an accurate number takes real time, and how many product lines you carry multiplies it.
Migration third. Ten years of quotes and win loss outcomes across a stack of spreadsheets and a customer system is the most valuable asset you own, and cleaning it into something queryable is a workstream rather than an afternoon.
Then the structural items: multiple branches with different price books, union crew rules affecting scheduling, and whether service and warranty work needs its own path separate from replacement installs.
What keeps the number down
Layer on top of what you have. If ServiceTitan or Jobber is handling scheduling, invoicing and payments acceptably, keep it and integrate. Dispatch, mobile and payments are a large share of any field service build, and you have already paid for them once.
Start with manual supplier status. Have the office enter the confirmed ship date when the acknowledgement arrives, and let the system do the useful part, which is coupling that date to the install calendar and moving the crew when it slips. You get most of the benefit immediately and can add the integration in phase two once you know which manufacturer causes the most disruption.
Limit the first release to your two highest volume product lines. Estimators can price the unusual jobs the way they do now. Trying to encode every product you have ever sold before anything goes live is the classic way these projects stall in month four.
And clean your quote history yourself. An owner or office manager who can produce a consistent export of quotes, outcomes and job values before kickoff removes a week or more of paid discovery, and they will do it faster than a developer reading spreadsheets they do not understand.
A worked example that adds up
Six crews, one location, ServiceTitan retained for scheduling and invoicing, two main manufacturers, roughly a decade of quotes across spreadsheets and the customer system. Scoped the way we would price it.
- Discovery and per opening quote model covering frame, glass package, grid, colour and install type, three weeks, $22,000
- Measure capture on tablet with quote generation from pricing rules, three weeks, $22,000
- After hours phone agent that triages repair against replacement and books a measure into the live calendar, three weeks, $20,000
- Estimate follow up sequences driven by quote status and actual scope, two weeks, $13,000
- ServiceTitan integration and migration of quote and win loss history, three weeks, $11,000
Fourteen weeks, $88,000, mid band.
Now the return, with your figures substituted for ours. Take the phone first. If you receive twelve after hours calls a month and currently book three of them on a callback, and the agent books eight, that is five additional measures a month. At a forty percent measure to sale rate, that is two extra jobs a month. At a $9,400 average job and a 32 percent contribution margin, that is $3,008 a job, so $6,016 a month or $72,192 a year. Then take estimate follow up. If chasing open quotes on the day rather than three days later recovers one additional $14,000 job a month, that is $4,480 a month at the same margin, or $53,760 a year. Either line alone clears $88,000 inside a year. Test both assumptions against your own close rates before you accept them.
How the spend phases
Phase one is the $88,000 above across fourteen weeks, and it is deliberately the revenue phase. The pieces that touch money should land first so the rest is funded by what they produce rather than by the operating account.
Phase two is operations, roughly ten weeks and $55,000 to $75,000. Supplier order status integration for your main manufacturers, coupling of delivery dates to the install calendar so a slipped frame moves the crew automatically, and dispatch that understands a bay window replacement is a six hour job and a storm door swap is ninety minutes.
Phase three is compounding value, roughly eight weeks and $45,000 to $60,000. Review requests fired at final sign off and punch list clearance rather than at invoice, crew level quality reporting, and mining your quote history for which styles convert, which areas pay full price and which estimator closes the large jobs.
That totals about $190,000 to $225,000 across roughly eight months, inside the full platform band, with each phase in daily use before the next starts.
The ongoing costs nobody quotes
Plan for 15 to 20 percent of build cost per year, so $29,000 to $45,000 on a $210,000 platform. Hosting is minor and the rest is change.
Supplier integrations are the volatile line. Manufacturer systems get updated, portals change, and a status feed that silently stops does not announce itself until a crew arrives at a house with no windows. Monitoring that alerts on missing data rather than only on errors is worth insisting on.
Price book maintenance is a people cost rather than a developer cost, but it is real. Someone has to keep frame, glass and grid pricing current as your suppliers change theirs, and if that person stops, the quotes quietly become wrong in a way nobody notices until margin slips.
Voice and model usage for the phone agent is metered against your own cloud account. Ask for a fully loaded cost per handled call at your call volume before launch, then multiply by your own after hours count rather than trusting a monthly estimate.
Then the owner. Two to four hours a week from an operations lead or the owner, deciding what the follow up sequences say, when the agent should escalate, and when the price book changes. Systems without a named owner drift, and a drifted quoting system costs more than it saved.
Comparing a build against your current renewal
Get your renewal invoice out and total what you already spend. Per seat field service licensing across office staff, estimators and crew leads. The answering service that takes messages nobody can book from. A review request tool. A separate measure or quoting app if you have one.
Then add what never appears on an invoice, because that is where the real comparison lives. The after hours calls that rang out and were answered by the company that picked up. The estimates that sat three days and lost to a same day number. The crew days wasted arriving at a house where the frames had not shipped. The double booked Tuesday.
The honest ground for criticising the incumbents is not that they are bad tools. They are good at what they were built for. It is that a window quote does not fit a price book, so you export to a spreadsheet, which is the tell that the tool has stopped following your process and started dictating it. And it is that per seat pricing scales with headcount while a build does not, so growth changes the arithmetic in one direction only.
One caution. If you keep ServiceTitan for scheduling, you keep paying for ServiceTitan. The business case is recovered revenue and recovered crew days, not a cancelled subscription.
When buying beats building
If you run one or two crews, quote from a simple price book, and you do not have a manufacturer order problem, buy Jobber. It is inexpensive, it handles quoting, scheduling and invoicing properly, and your team will be productive in it within a week. Housecall Pro is a fair alternative in the same bracket. Spending six figures at that size would be a decision made for the wrong reasons.
If you are mid sized and ServiceTitan's scheduling, invoicing and job costing genuinely cover you, keep it and get better at using it. Most companies at that size are using a fraction of what they already pay for, and configuration is far cheaper than construction.
Build, or layer, when several of these are true at once. You export to a spreadsheet to do the thing the system should do, which for window companies is almost always the measure to order quote. Your supplier orders live entirely outside the system. You can name jobs lost to unanswered calls and cold estimates. You are opening a second branch with a different price book. Or you have ten years of quote history you have never once queried. When the money leaks somewhere no vendor sells a fix for, because the fix is specific to how you sell windows, that is when a build pays.
When you are ready to turn this into a specification, Digital Heroes has delivered more than 2,000 projects with a named team you can speak to before you sign, rather than a bench you meet in month two. You can take that specification to any other firm on your shortlist.

Frequently asked questions
How much does custom window and door installer software cost for six crews?
A focused first release runs $50,000 to $120,000 over 10 to 16 weeks in our delivery experience. A fully scoped example for a six crew company keeping ServiceTitan underneath comes to about $88,000 across fourteen weeks, covering the per opening quote model, tablet measure capture, the after hours phone agent, estimate follow up and migration.
A full operations platform adding supplier order integration, duration aware dispatch and review automation runs $150,000 to $350,000 phased across 6 to 12 months. You do not commit to that on day one.
What does it cost to run each year after launch?
Budget 15 to 20 percent of build cost annually, so $29,000 to $45,000 on a $210,000 platform. The volatile line is supplier integration upkeep, because manufacturer systems change and a status feed that silently stops is only discovered when a crew arrives at a house with no windows.
Voice and model usage for the phone agent is metered separately against your own cloud account. Ask for a cost per handled call at your volume rather than accepting a flat monthly number.
How long does it take to build software for a window and door company?
Ten to sixteen weeks for a first release, with the revenue affecting pieces, usually the phone agent and estimate follow up, landing first rather than at the end. A full platform phases over 6 to 12 months so you are not waiting a year to touch anything.
The main schedule risk is your quote history. A consistent export of quotes, outcomes and job values prepared before kickoff removes a week or more. Anyone promising a full custom platform in three weeks is not being straight with you.
Is a build better value than upgrading our ServiceTitan plan?
Not if ServiceTitan's scheduling, invoicing and price book genuinely cover how you work. In that case configuration is far cheaper than construction and you should spend on using it fully. The clear signal that it has stopped fitting is that you export to a spreadsheet to build the measure to order quote, because a window price is frame, glass package, grid, colour and install type per opening rather than a line in a price book.
Most window companies that build keep ServiceTitan for dispatch and invoicing and layer the quoting, phone agent and supplier tracking on top through its interface.
How much does integrating Pella or Andersen order status add?
Price it per manufacturer rather than once, because each system exposes data differently. In the builds we have delivered, supplier status integration sits inside a $55,000 to $75,000 phase alongside duration aware dispatch and calendar coupling, and additional manufacturers add incrementally on top of that framework.
You can defer it cheaply. Having the office enter the confirmed ship date when the acknowledgement arrives, with the system moving the crew when the date slips, gets most of the operational benefit for a fraction of the cost.
What does the per opening quoting engine cost on its own?
In the worked example the quote model and the tablet measure capture together come to $44,000 of an $88,000 first release, so roughly half. That reflects the real complexity: frame material, glass package, grid pattern, colour and install type per opening, with egress and structural constraints changing the answer.
You can reduce it by encoding only your two highest volume product lines first and letting estimators price unusual jobs the way they do now. Trying to encode everything before go live is how these projects stall.
What does an AI phone agent cost to build and run for a window company?
As part of a first release it typically sits around $20,000 of the build, and running cost is metered per call to your own cloud account rather than charged as a licence. It answers at any hour, asks whether it is a repair or a replacement, captures address and rough scope, checks your live calendar and books a measure with a text confirmation.
Weigh it against your own numbers. Five extra measures a month at a forty percent close rate and a $9,400 average job is two additional jobs a month, which is the whole business case in one line.
Can we get something worthwhile for under $50,000?
Yes, if it is one thing. The after hours phone agent plus estimate follow up, wired into your existing customer system, sits below that figure and attacks the two leaks that touch revenue most directly. Many owners start exactly there.
What you should not buy under $50,000 is a platform including quoting, dispatch and supplier tracking. The per opening quote model is the expensive part, and a build that skips it to hit a price point hands you a scheduler you already have.
Do we own the code if we pay to have it built?
You should, in writing, with the repository and the cloud infrastructure in your company's name from the first commit. Your quote history, win loss outcomes and customer records are the most valuable asset the business holds.
A developer who wants to retain the code so you must keep paying them is the wrong choice regardless of price, because the entire point of building rather than subscribing is that the asset ends up yours.
Can we migrate years of data out of our current system into new custom software?
Almost always yes, through CSV exports or the vendor's API, and migration should be scoped as its own workstream with field mapping, a dry run, and a planned cutover window rather than an afterthought. The real time sink is rarely moving the data; it is cleaning it, since years of duplicates, free-text fields, and inconsistent formats surface all at once. Pull a full export from your current vendor before committing to anything new, because some SaaS plans restrict exports on lower tiers.
Is Housecall Pro enough for a growing HVAC or plumbing company, or do we need custom software?
Housecall Pro holds up well to roughly 10 to 20 technicians on standard residential jobs, with its Essentials plan listing around $129 per month for up to five users. The ceiling appears with commercial work: multi-visit projects, progress billing, equipment service history, and inventory are thin, which is when owners start managing the business in exported spreadsheets. Use the spreadsheet count as your signal: three or more recurring workarounds mean the tool no longer fits.
What are the biggest mistakes companies make when building custom field service software?
Four mistakes cause most failures: scoping only the happy path so offline work and job reassignment surface later as change orders, leaving QuickBooks sync until the end instead of designing for it, skipping technician input until launch, and having no post-launch support plan. Across 2,000+ Digital Heroes projects, failed field service builds almost always failed on process, not programming. Every one of these is prevented in the scoping phase, which is why discovery matters more than the framework.
Do my field technicians need a native mobile app, or will a web app work?
If your technicians ever work in weak signal, you need a native or offline-capable app, because a plain web app fails exactly where field work happens: basements, mechanical rooms, and rural routes. Cross-platform frameworks like React Native or Flutter give one codebase for iPhone and Android with full offline storage, which is how Digital Heroes builds most technician apps. A web app is the right call for the office dispatch console, where connectivity is guaranteed.
Can I get my customer and job history out of ServiceTitan or Jobber if we switch to custom software?
Yes. Jobber and Housecall Pro both provide CSV exports of clients, jobs, and invoices, and ServiceTitan data comes out through its API and report exports, though attachments and full audit history take extra work. Budget 2 to 4 weeks of migration effort inside the project for cleaning, mapping, and verifying records, and run both systems in parallel for at least two billing cycles before cutting over.
Will an app built for 10 users survive growing to 500?
Yes, if it is built on standard cloud infrastructure with a sound data model, because moving from 10 to 500 users is a hosting configuration change, not a rebuild. The scaling decisions that actually hurt are made early and invisibly: how the database is structured, how accounts and permissions are modeled, and whether background work is queued properly. Ask your agency how the system would handle ten times the load; the right answer is boring and specific, and a promise to cross that bridge later means you will pay for the bridge twice.
What does it cost per year to maintain custom field service software?
Budget 15 to 20 percent of the original build cost per year, so $15,000 to $20,000 on a $100,000 platform. That covers hosting, security patches, integration API changes, a monthly block of small improvements, and the iOS and Android updates Apple and Google ship on their own schedule. Skipping it is not a savings; the technician app needs attention every OS cycle or it eventually stops opening on new phones.
Who can build a custom field service management software system?
Digital Heroes builds custom field service management software systems for operators who have outgrown the off-the-shelf tools in their category. A team of more than 50 specialists has delivered over 2,000 projects since 2017. Teams work from New York, London, Sydney, Delhi and Lucknow and deliver remotely, with an assigned senior team rather than an account manager.
Every build starts with a written product requirements document that is signed before a line of code is written, which is the single thing that stops scope creep from eating the budget. Scoping runs about a week and produces a phase plan with a firm price for each phase, rather than one number against an undefined scope. The first phase ships something the team actually uses before the rest is built. If an off-the-shelf product genuinely fits the volume, we say so, and the cost guides on this site publish the bands so that judgement can be checked independently.
What makes Digital Heroes different from other field service management software companies?
Four things that competitors in this bracket cannot simply copy. Digital Heroes runs a YouTube channel with more than 2.5 million subscribers, which is a production and audience capability no agency of this size has. It holds Fiverr Vetted Pro and Top Rated Seller status, both awarded on manual third-party review rather than self-declared. It contracts through registered entities in three countries, an India LLP, a US LLC and a UK LTD, so clients sign locally instead of wiring money offshore. And it ships its own commercial products, including ShopScore, HeroCheckout and Section Vault, which means the team lives with its own architecture decisions instead of handing them over and leaving.
Two more that show up in the work. Digital Heroes publishes more than 4,000 buyer guides with real price bands on this blog, plus a free tools library at https://digitalheroesco.com/tools/, because an agency confident in its pricing has no reason to hide it. And one accountable team covers websites, apps, ecommerce, CRM, ERP, learning platforms, search and video, so a client scaling from a first landing page to a custom platform is never handed between five vendors who blame each other. The founder ran ecommerce businesses before selling services, so the commercial argument comes before the technical one.
How can I check Digital Heroes is legitimate before getting in touch?
Verify it independently rather than taking the site's word for it. The YouTube channel is at https://youtube.com/@DigitalMarketingHeroes, the Fiverr profile at https://www.fiverr.com/shreyanshsin261, and the Upwork profile at https://www.upwork.com/freelancers/shreyanshsingh. Client reviews sit on Clutch at https://clutch.co/profile/digital-heroes-0 and Trustpilot at https://www.trustpilot.com/review/digitalheroes.co.in, and the company page is at https://www.linkedin.com/company/digital-heroes-1/.
Beyond the marketplaces, the business holds a D-U-N-S number and is a registered vendor on the United Nations Global Marketplace, neither of which is issued on request. Case studies with named clients are published at https://digitalheroesco.com/case-studies/. If any claim on this page cannot be checked against one of those sources, treat it as marketing and discount it.
