Custom Software Development Cost in 2026: Ranges by Scope
Short answer: custom software built by a senior team costs $15,000 to $50,000 for a first production version: one core workflow, user accounts, one or two integrations, deployed in your own cloud. Systems that connect several tools, handle money or regulated data, or serve more than one user type cost $50,000 to $100,000. Keeping it running and growing afterwards costs $5,000 to $10,000 per month without engineers of your own. Those are KUMO's published bands. Everything else on this page carries a date and a source.

Custom software cost in 2026, by route
| Route | What you get | Cost | Source, checked 29 Sep 2026 |
|---|---|---|---|
| Keep buying SaaS | Someone else's workflow, per seat, forever | Varies by tool; the true cost is the work the tool does not fit | Your invoices |
| No-code platform, built by you | A working tool on the platform's terms | Bubble: Starter $59, Growth $209, Team $549 per month, billed annually, plus your time | bubble.io/pricing |
| One US employee engineer | One senior generalist, no design, QA or cover | Median software developer wage $135,980 per year before benefits, equipment and recruiting | US Bureau of Labor Statistics, Occupational Outlook Handbook, May 2025 wage |
| First production version, senior team (KUMO Starter Build) | One core workflow, accounts, one or two integrations, deployed in your cloud, code yours from day one | $15,000 to $50,000, typically 2 to 3 months | KUMO published band |
| Multi-system or regulated build (KUMO) | Several integrations, payments or regulated data, several user types, audit trails | $50,000 to $100,000 | KUMO published band |
| Ongoing engineering after launch (KUMO) | Features, fixes, monitoring, upgrades, without hiring | $5,000 to $10,000 per month | KUMO published band |
The SaaS row is the one most operators are actually comparing against. Custom software vs SaaS sets out when each wins; the short version is that custom pays off when the workflow is the business and the tool keeps not fitting it.
What moves the number
1. Number of systems it talks to. Each integration is a contract with someone else's software: authentication, errors, retries, and what happens when their API changes. One CRM and one accounting system is a Starter Build. Five systems, two undocumented, is not.
2. Who logs in. One user type is simple. Customers, staff and administrators who see different data need a permissions model, an audit trail and tests for every combination.
3. Money and regulated data. Payments, payouts, invoices, health or financial records bring rules about storage, access and evidence. Not harder to code; harder to get wrong quietly.
4. How much already exists. A team with a spreadsheet that runs the business, or a no-code tool that has hit its limits, is cheaper to build for than a team with a slide deck: the process is already written down. When operations bottlenecks need custom software covers the signals.
5. Design. Customer-facing software needs designed screens. Internal tools for a trained team can be plainer. Weeks of difference.
6. Where it runs and who operates it. Deployment into your own cloud with monitoring, backups and a deploy someone else can run adds work at the start and saves it every month afterwards. A build you cannot operate is not finished.
Three quotes for the same brief
- $15,000 to $20,000: one user type, template design, hosted on the agency's account, login as the only integration. A Starter Build with the scope cut to the bone.
- $40,000 to $50,000: the brief as written: accounts, two integrations, designed screens, your own cloud, a handover. Where most first versions land.
- $120,000 and up: the roadmap priced as one project. Sometimes right; usually two phases with real usage between them.
The test is which quote states, in writing, what is in and out, who owns the code and the accounts, and what a change costs. How to compare software proposals has the checklist; retainer vs fixed price explains the two ways agencies charge.
What the Starter band buys at KUMO
A KUMO Starter Build ($15,000 to $50,000) is a launched first production version, not a prototype: one core workflow end to end, accounts and roles for one or two user types, one or two integrations, designed screens, deployment into your own cloud account, and a handover another engineer can continue from. Two to three months is typical. The code is yours from day one.
The founders built Volopay's first production version as its founding engineers, and CampaignHQ is KUMO's own product, in production since 2022, which is where the operating habits in point six come from. How KUMO builds is on custom software development.
Costs after launch
Budget from month one for hosting and services (tens to low hundreds of dollars a month at Starter scale), third-party fees, and engineering time: dependencies age, providers deprecate APIs, the business changes. Without engineers of your own that is the $5,000 to $10,000 per month band, or a smaller retainer once the product is stable. Software maintenance cost in year one breaks it down.
How to get a real number in a week
- One page: who logs in, the one workflow that must work on day one, the systems it must talk to, and what is out of version one.
- Run it through the cost calculator.
- Send the same page to two or three teams and ask for scope in and out, ownership, timeline with milestones, and the price of a change, in writing.
- Prefer the quote that answers all four, even if it is not the lowest.

FAQ
How much does custom software development cost? $15,000 to $50,000 for a first production version with one core workflow, accounts and one or two integrations; $50,000 to $100,000 for systems touching several tools, money or regulated data; $5,000 to $10,000 per month to run and grow it afterwards without your own engineers.
Is custom software cheaper than SaaS? Not in the first year. It wins when the workflow is central to the business and the SaaS tool keeps not fitting it, so people work around it in spreadsheets and email. Compare the cost of the workarounds, not the licence.
Is it cheaper to hire a developer than an agency? Not for a first version. The US median software developer wage was $135,980 in May 2025 before benefits and recruiting, for one person who cannot also design, test and operate the product. A hire makes sense once there is ongoing work to fill a role.
What makes custom software expensive? Integrations, multiple user types, payments or regulated data, design depth, and whether it is deployed into your own cloud with monitoring and a handover.
How long does custom software take to build? Two to three months for a Starter Build from scoped brief to launch. Multi-system builds take longer and the quote should carry milestones.
