How much does custom business software cost in 2026?

The honest short answer: custom business software is mostly people's time, so it costs what a team costs for as long as the work takes. Below is what teams and projects cost in 2026, with a source for every figure, so you can set a budget before you talk to anyone.

What you are paying for

Almost all of the cost of custom software is engineering time: the people who define it, design it, build it, test it and keep it running. Hosting and licences are usually small next to that. So the two questions that set the price are how big a team the work needs, and for how long.

What makes a project bigger is easy to list: more kinds of user (staff, customers, managers), more systems to connect to, mobile apps as well as a web app, data that has to move over from an old system, and rules your industry imposes. What makes it smaller is a clear first problem and one person on your side who can decide.

What teams cost in 2026

Rates depend mostly on where the team is and how senior it is. Published figures for senior developers, by hour:

• North America: USD 125 to 250 or more, and Western Europe USD 150 to 165, according to Keyhole Software's data from its own projects (January 2026). For scale, the median US software developer salary is USD 135,980 a year (US Bureau of Labor Statistics, May 2025); agency rates sit well above salaries because they include overhead, management and idle time.
• Nearshore and offshore: Latin America USD 60 to 75, Central and Eastern Europe USD 64 to 76, and Asia USD 31 to 41, from Accelerance's 2026 rate survey of 60 outsourcing partners. It reports rates edging down into 2026.
• English-speaking studios in Japan: USD 100 to 199 an hour, with minimum projects of USD 5,000 to 10,000, on their Clutch listings (for example Skydea, Studio Five and Tacchi Studios, checked October 2026). At about 160 hours a month, one full-time person comes to roughly USD 16,000 to 32,000 a month.
• Japanese domestic firms: the JUAS 2025 software metrics survey puts the average outsourcing price for new builds from scratch at JPY 960,000 per person-month. Levtech's rate guide puts engineers with 3 to 5 years' experience at JPY 800,000 to 1,000,000 a month, 5 to 10 years at JPY 1,000,000 to 1,200,000, and over 10 years at JPY 1,200,000 to 2,000,000.
• Singapore agencies: SGD 80 to 200 an hour, with senior developers at about SGD 130 to 200, according to Naveck and Best of Singapore (accessed October 2026).
• Do-it-yourself tools such as Glide or AppSheet, for simple needs. Cheap to start, and fine until the process outgrows them.

Averages across the whole market look lower because they include many small firms. Clutch's pricing guide (September 2026), built from verified client reviews, finds most firms charge USD 25 to 49 an hour and puts the average project at about USD 132,000 over about 13 months.

What a project costs

Ranges by size from Keyhole Software, a US firm, based on more than 200 of its projects:

• A simple app or first version: USD 40,000 to 120,000, over 2 to 4 months.
• A mid-sized system: USD 120,000 to 300,000, over 4 to 8 months.
• A complex platform: USD 300,000 to 1,000,000 or more, over 8 to 18 months or longer.

These are one firm's figures at North American rates, and Keyhole notes that the variables above can move a budget by 30 to 50%. A team in a lower-cost market, or a smaller first release, brings the number down. Starting with the one process that costs you most is the most reliable way to keep the first budget small.

After launch

Software needs looking after once it is live: OS updates, security patches, fixes and small changes. A common rule of thumb is 15 to 25% of the build cost each year (Keyhole Software). A 2026 benchmark of 24 SaaS products by Wavect found medians of 24% in the first year, 21% in the second and 26% in the third, and suggests 10 to 16% for a quiet internal tool. If you would rather not own the software at all, a managed app is a monthly fee instead; how much a managed app costs explains that route.

How AI changes the cost

Nearly every developer now uses AI tools. In the Stack Overflow 2025 survey, 84% use them or plan to, but 46% distrust their accuracy, and 66% say the most common problem is answers that are almost right, but not quite. Google's DORA 2025 report found AI use linked to faster delivery, but still to less stable software.

Whether AI makes projects cheaper is less clear than vendors claim. A controlled study by METR found experienced developers took 19% longer with early-2025 tools. Its February 2026 update estimates small speed-ups with newer tools, and calls that evidence weak. Routine code is faster to write; deciding what to build, and checking that the result is correct and secure, still takes senior people's time. Treat a quote that assumes AI makes the work nearly free with caution.

Is it worth it?

Compare the cost with what the current process already costs you in staff hours, mistakes and missed work. If a process takes several people a few hours every week, it is already costing you a meaningful share of a salary, every year.
