Key Takeaways
- Clutch's verified client reviews put the average software project at about $132,480 and 13 months. Almost every other public price range comes from a firm selling the work.
- In construction and manufacturing, integrations, field or shop-floor conditions, and compliance move the price more than the hourly rate does.
- Development firms commonly put yearly upkeep at 10 to 25% of the build cost. No independent study backs one number, so get yours in writing.
- Compare a license and a build over the same three to five years, including seat growth, renewals, and implementation.
- A fair quote names the integrations, the year-two owner, and what's out of scope.
If someone quoted you six figures for custom software, you heard the number that matters least.
The quote covers the build. But what you end up paying will likely depend on the systems it has to connect to as well as the conditions it has to work in.
And don’t forget that there are also costs for running the solution in year two and beyond.
So what should you know about build vs buy in the age of AI? Here's how we'd read a quote in construction or manufacturing based on the current data – as well as what our team of experts say on the subject.
How much does custom software cost in 2026?
The answer is about as vague as the term “custom software”. There was a time when that meant something concrete, but AI has now made custom software available to nearly anyone with a Claude or Cowork subscription.
In our case, we’re talking about custom software that’s designed to help mid-level to enterprise teams enhance their operations and connect the dots between data-heavy systems.
Clutch's verified client reviews put the average software project at about $132,480 over roughly 13 months, as of its September 2026 update. The same page lists $10,000 to $49,000 as the typical range, which tells you how wide the spread is.
Rates vary by region. Clutch shows $50 to $99 an hour for US firms, and $24 to $49 as the most common band overall.
Keyhole Software, a US development firm, builds its bands from its own 200-plus projects. A simple build runs $40,000 to $120,000 over two to four months. A medium one runs $120,000 to $300,000 over four to eight months. A complex system starts around $300,000 and can pass $1 million, with timelines of 18 months or more.
Hiring is the other route. The Bureau of Labor Statistics puts median pay for US software developers at $135,980 (May 2025). That's salary alone, before benefits, tools, or the management time a developer needs.
One caution on all of it. Apart from Clutch and the BLS, these numbers come from firms that sell the work. Read them as the market describing itself.
What drives the cost of custom software in construction and manufacturing?
We’ve found that there are five things that move the number more than the hourly rate:
| Driver | Why it moves the price | What to ask |
|---|---|---|
| Integrations with job cost, accounting, ERP, or MES | Each system has its own data rules, and a code in one rarely matches a code in another | Which systems connect, and who owns each connection? |
| Offline use and field devices | Crews lose signal, so the app has to work without it and sync later | Does it work offline, and what syncs when the signal returns? |
| Shop-floor data and traceability | Equipment, scanners, and lot or serial tracking all have to feed the record | Which devices connect, and which records must be traceable? |
| Compliance and audit trails | Safety and quality records need review, logging, and sign-off | Who signs off, and what gets logged? |
| Sites, roles, and users | More sites and permission levels mean more to build and test | How many roles and sites at launch, and who administers them? |
Start with integrations
Bolder Apps, a development firm that works with Procore, prices a Procore-to-ERP financial sync at $25,000 to $40,000 over six to eight weeks. A custom field app that uses Procore data runs $50,000 to $80,000 over eight to twelve weeks.
The reason is mapping. As the firm puts it, cost codes in Procore don't automatically match job cost categories in Sage, and someone has to decide how they line up.
Then there's the field
Bolder Apps says offline-first architecture adds 30 to 40% to a mobile build. In its words, "a foreman standing in a concrete pour does not have time to troubleshoot a loading spinner."
On the manufacturing side, we found no usable US price range for a custom build, and we won't invent one. The drivers are the same kind. Equipment and scanners have to connect to your ERP or MES. Lots and serial numbers have to be traceable, with an audit trail your customers expect.
AI coding tools have shortened the first build. They haven't shortened the mapping, the field testing, or the audit trail. That work still takes people.
What does custom software cost after launch?
Development firms commonly put annual maintenance and support at 10 to 25% of the build cost. Keyhole says 15 to 25%. Modall, a Canadian firm that builds construction software, says 10 to 20%.
Neither cites an independent study for it, so treat the range as a rule of thumb. On a $150,000 build, 10 to 25% is $15,000 to $37,500 a year.
Keyhole adds hosting, security, and compliance on top. It puts security and compliance work alone at $5,000 to $50,000 a year or more. It also warns that organizations often skip the maintenance budget and pile up technical debt.
The line most quotes leave out is a name. Someone has to own the app in year two, fix what breaks, and change it when your process changes. We cover that in more depth in our guide to the build vs. buy decision.
Process matters here too. An app built on an undefined process costs more to maintain, because every fix turns into a debate about how the work should go. That's why we start with Structure Before AI.
And a build that stalls costs money without producing anything. We wrote about that in The Hidden Cost of a Half-Built Quickbase App.
What does buying cost by comparison?
Less visible than you'd expect, because many vendors don't publish prices.
Procore quotes by company type and annual construction volume. Its pricing page describes fixed annual contracts with unlimited users and renewal rate protection, and lists no prices. Third-party estimates vary widely, which tells you how much depends on your volume.
Mendix publishes list prices. As of September 30, 2026, its Standard plan starts at $1,090 a month for one app and $2,725 a month for unlimited apps. Cloud hosting costs extra, and Premium is by quote.
Manufacturing software prices by whatever the product counts. Harmoni's August 2026 roundup lists Tulip at $100 to $250 per interface per month with a 10-interface minimum, or $12,000 to $30,000 a year. It lists Microsoft Dynamics 365 Supply Chain Management at $210 to $300 per user per month, which it puts at $630,000 to $900,000 a year for 250 users, license only.
Harmoni sells manufacturing software itself, so weigh its next claim accordingly. It says implementation at that tier often costs about as much as the license.
Buying can overrun too. Panorama Consulting's 2026 ERP survey of 170 organizations found more than a quarter went over budget. Among those, the most common reason was an unexpected need for additional technology.
Buying fails in other ways, too. We've written about why construction's software graveyard keeps filling up and why Procore alone doesn't solve operations.
When does a custom build cost less than a license?
When you'd keep paying for the same gap year after year. The method is simple, and you can run it in a spreadsheet.
Add up the license over three to five years: the subscription, the seats or volume you'll add, implementation, and the workarounds your team keeps building around it. Then add the build and its upkeep over the same years.
If the build comes out lower, or close, and fits your process better, you have your answer.
Geisinger Health System ran that math. It was paying $100,000 each for two compliance systems, replaced them with one custom application, and now saves more than $200,000 a year.
That's a healthcare case, and the arithmetic carries over to construction and manufacturing.
Skinder Construction kept its system of record and added an AI layer that reads incoming bid emails and turns them into standardized Quickbase records. It saves hundreds of hours a month. Nobody retypes an inbox.
What should a fair custom software quote include?
A fair quote leaves you nothing to discover later. Look for six things:
- The integrations, listed, with an owner for each. Which systems connect, and who fixes a connection when one of them upgrades.
- Field and device scope. Whether it works offline, on which devices, and what syncs when the signal returns.
- A named year-two owner and a number. Who maintains it, and what that costs per year, in writing.
- Hosting and security as their own lines. They shouldn't hide inside the build price.
- What's out of scope. Data migration and training are often priced separately, so ask.
- How changes get priced. Scope shifts mid-project, and Keyhole reports unplanned additions stretch timelines by 15 to 30%. Agree on the rule before it happens.
When every line is on the page, nothing surprises anyone. That's the standard we hold ourselves to: clients should feel heard and never be surprised.
It's also where we partner, we don't vanish. Our Ongoing Development Plan gives the stretch after launch a known number on the budget line.

Frequently Asked Questions
How much does custom software cost in 2026?
Clutch's verified client reviews put the average software project at about $132,480 over roughly 13 months, with $10,000 to $49,000 listed as the typical range. Integrations, field requirements, and compliance move the price more than the hourly rate. Ranges from development firms vary by scope.
What drives the cost of custom software for construction and manufacturing?
Integrations with job cost, accounting, ERP, and MES systems, plus field and shop-floor conditions such as offline use and device connections. One US development firm reports offline-first architecture adds 30 to 40% to a mobile build.
How much does custom software cost to maintain each year?
Development firms commonly estimate 10 to 25% of the build cost per year, plus hosting and security. No independent study backs a single figure, so ask for the number in writing, along with the name of whoever owns the app after launch.
Is custom software cheaper than buying?
It depends on the years you compare. Add the license, seat or volume growth, implementation, and renewals over three to five years, then compare that with the build plus upkeep over the same period. Geisinger replaced two $100,000 systems with one custom app and saves more than $200,000 a year.
How do you compare custom software quotes?
Check that each quote lists its integrations with owners, field and device scope, a named year-two owner with a yearly cost, hosting and security as separate lines, what's out of scope, and how changes get priced. A quote missing any of these will surface the gap later.
