How Much Does Custom Software Development Cost?
By Norman Dilthey, Founder, Koana Labs · Published · Updated · 5 min read
Custom software typically costs $40,000 to over $1,000,000 depending on scope, with simple tools at $40,000-$120,000 and advanced systems at $120,000-$300,000 ([daily.dev](https://daily.dev/posts/what-custom-software-costs-in-2026-the-11-factors-i-walk-every-client-through-80l2awjuw)). Budget 15-25% of build cost yearly for maintenance, and expect quotes to vary since real engineering costs fell 40-70% since 2022 ([workflowunity.io](https://workflowunity.io/how-much-does-custom-software-development-cost/)).

How much does software development cost
"Software development cost is the total investment required to design, build, test, deploy, and support a software product... not just the price on a development quote" (hiredeveloper.dev).
Many online guides publish very wide ranges, including $10,000 to $500,000 (hiredeveloper.dev) and $15,000 to $2 million (workflowunity.io). Those ranges can be technically correct and still useless for budgeting.
Most buyers price only the build phase. Quotes often exclude cloud, licenses and ongoing support, and that is where the budget gaps show up later (hiredeveloper.dev).

How much does it cost to develop custom software
Custom software usually ranges from $40,000 for simple tools to over $1,000,000 for complex enterprise systems (daily.dev).
Simple software with minimal features on one platform is often $40,000 to $120,000. Advanced software with several integrations and user roles is often $120,000 to $300,000 (daily.dev).
Build cost is only part of the total. Ongoing maintenance and support typically adds 15-25% of build cost per year (daily.dev).
How much does custom software development cost in 2026
In 2026 the published price bands are still broad, but delivery economics differ sharply between vendor models (workflowunity.io).
A WorkflowUnity analysis states that structural build cost dropped 40-70% between 2022 and 2026 while many vendors still quote on older assumptions (workflowunity.io). The same analysis says a project that cost $250,000 three years ago can be $90,000 today under current engineering economics (workflowunity.io).
That is one reason two quotes for the same scope can differ widely. Price alone tells you nothing about team structure, delivery method or efficiency.
What factors affect the cost of custom software development
Project scope, team setup and delivery method shape custom software cost together (daily.dev, andersenlab.com).
| Factor | What it covers | Cost impact |
|---|---|---|
| Scope and feature list | Functionality needed at launch | Sets the baseline band, often $40,000-$300,000 or higher (daily.dev) |
| Team location and seniority | Geography and skill mix | Can move the total substantially |
| Pricing and engagement model | Fixed price against time and materials | Shifts who carries risk and how flexible the budget is |
| Platform choice | Web, desktop, native, cross-platform | Native on several platforms usually costs more |
| Integrations and APIs | Links to third-party systems | Adds discovery, implementation and QA effort |
| Data migration | Moving and cleaning legacy data | Routinely underestimated at proposal stage |
| Compliance and audit needs | GDPR, HIPAA, PCI DSS, SOC 2 | More security, documentation and review work |
| Architecture complexity | Scalability, resilience, performance targets | Raises both initial build and long-term support effort |
| Post-launch support | Bug fixes and iterative updates | Typically adds 15-25% per year (daily.dev) |
These factors interact rather than stack cleanly. Compliance multiplies integration effort, because every integration then needs its own testing and controls evidence.
What is the 40/20/40 rule in software engineering
The 40/20/40 rule is a rough split: 40% planning and design, 20% coding, 40% testing and QA.
Teams use it as a sanity check, not a law. It reflects a common pattern where unclear requirements and weak testing create expensive rework later.
Phase-based cost models follow the same logic and include discovery, UX/UI, development, QA, project management and DevOps deployment (andersenlab.com). If a quote nearly ignores discovery or QA, ask why.
How is custom software development priced (fixed price vs hourly rate)
Custom software is commonly priced as fixed price, or as time and materials billed by hour or sprint (daily.dev).
| Model | How it works | Best for | Main risk |
|---|---|---|---|
| Fixed price | One agreed price for a defined scope | Stable, well-specified projects | Change requests add cost and delay |
| Time and materials | Billing for actual hours or sprints | Evolving scope and discovery-led work | Less certainty about the final total |
How much does it cost to hire a software development team vs agency
In-house and agency models can produce very different costs for the same scope, because staffing and utilization differ (workflowunity.io).
Workflow assumptions matter. Some firms still use 2022 staffing patterns, often three-to-five-person teams, which can inflate cost against newer approaches (workflowunity.io).
Before you compare options, ask each vendor how many people will work on the project daily, what seniority mix they use, and how they map scope to effort.
What are hidden costs in custom software development
Hidden costs usually appear after the build quote (andersenlab.com).
- Maintenance and support, commonly 15-25% of build cost per year (daily.dev)
- Cloud hosting and operations costs that grow with usage (andersenlab.com)
- Training, change management and license fees (andersenlab.com)
- Data migration work, usually underestimated early (andersenlab.com)
Ask for the build, run and support assumptions before anyone signs the contract.
How can businesses reduce custom software development costs
You cut cost by tightening launch scope, picking the right pricing model and refusing outdated staffing assumptions.
Run this checklist before you request final quotes:
- Separate must-have launch features from later enhancements.
- Pick fixed price only if requirements are stable.
- Ask how many engineers will work daily, and at what seniority.
- Confirm who owns support, hosting and updates after launch.
- Compare quotes by scope and staffing model, not by headline price.
WorkflowUnity also reports that scope once priced at $250,000 can be delivered at $90,000 under current engineering economics (workflowunity.io). If a quote sits far above that, ask for an explanation at the level of the delivery model.
How long does custom software development take and how does timeline affect cost
Timeline affects cost directly, and both long and rushed projects add effort.
Longer timelines usually increase total labor. Compressed timelines can also increase cost, because the team has to scale up quickly for the same scope.
Development pace is a known cost factor alongside architecture complexity and integration depth (andersenlab.com). Simple projects in the $40,000-$120,000 band often move faster than advanced projects in the $120,000-$300,000 band, because the integration and testing cycles are lighter (daily.dev).
Worked example: estimating your own project cost
You can build a first-pass budget from the published build bands plus the annual maintenance percentage.
- Classify scope as simple, advanced or complex enterprise.
- Use $40,000-$120,000 for simple builds (daily.dev).
- Use $120,000-$300,000 for advanced builds (daily.dev).
- Use above $1,000,000 for complex enterprise scope (daily.dev).
- Add 15-25% of build cost each year for maintenance (daily.dev).
- Example: at a build cost of $150,000, plan about $22,500-$37,500 a year for maintenance.

Frequently asked questions
Is a cheap custom software quote a red flag?
Not necessarily. Structural engineering costs fell 40-70% between 2022 and 2026, so a lower quote can simply reflect a modern, leaner staffing model rather than lower quality ([workflowunity.io](https://workflowunity.io/how-much-does-custom-software-development-cost/)). Ask how the team is staffed before judging a price on size alone.
How much should I budget for ongoing costs after launch?
Plan for 15-25% of your build cost every year in maintenance and support, on top of hosting and any license fees ([daily.dev](https://daily.dev/posts/what-custom-software-costs-in-2026-the-11-factors-i-walk-every-client-through-80l2awjuw)). For a $150,000 build, that is roughly $22,500-$37,500 annually.
Should I choose fixed price or time and materials?
Choose fixed price when requirements are stable and well documented, and time and materials when the project is likely to evolve. Locking scope too early on an unclear idea tends to produce expensive change orders later.
Why do custom software quotes vary so widely between vendors?
Many vendors still quote using 2022 engineering economics and staffing models, while others price with current methods, so the same scope can show up as $250,000 from one firm and $90,000 from another ([workflowunity.io](https://workflowunity.io/how-much-does-custom-software-development-cost/)).
What is the fastest way to get an accurate cost estimate?
Write down your core launch features, classify your project as simple, advanced, or complex enterprise using the published bands, then ask a vendor to quote against that scope with a clear staffing explanation rather than a generic range.
How much does custom software development cost for most business projects?
Most published guidance places custom software between $40,000 and $300,000 for simple to advanced scope, with complex enterprise projects above $1,000,000 (daily.dev). Map your project to a scope class first, then adjust for integrations, compliance and support.
What hidden costs should I ask about before signing?
Ask for line items on maintenance, cloud operations, training, change management, licenses and data migration (andersenlab.com). Maintenance alone is commonly 15-25% a year (daily.dev). A lifecycle budget is more reliable than a build-only quote.
Why can two vendors quote very different prices for the same scope?
The difference usually comes from staffing model and delivery economics rather than scope. WorkflowUnity reports that structural costs have dropped 40-70% since 2022, while some firms still estimate with older team assumptions (workflowunity.io). Ask each vendor to put team size, seniority and execution model in writing.
