How Much Does Custom Software Development Cost in 2026?

By Prominetix Team · · 6 min read

Almost every project starts with the same question: how much will this cost? The honest answer is "it depends", but that does not have to be vague. This guide explains what drives the price of custom software and how to plan a realistic budget.

What drives the cost of custom software

  • Scope and features: every screen, role and workflow adds design and engineering time.
  • Complexity: payments, real-time features, AI, and complex business rules cost more than standard forms and lists.
  • Integrations: connecting to CRMs, ERPs, payment gateways and legacy systems is often the hardest part.
  • Platforms: web only is cheaper than web plus iOS and Android.
  • Design quality: a polished, researched UX takes more time than a basic interface, and usually pays for itself.
  • Team and location: senior engineers cost more per hour but usually deliver faster and with fewer defects.

Typical cost ranges by project type

These are indicative market ranges, not a quote. Your actual cost depends on the factors above, and we are happy to give you an estimate for your specific project.

Project typeTypical rangeTypical timeline
Simple MVP or internal tool$10k – $40k6 – 12 weeks
Business web application$40k – $120k3 – 6 months
Mobile app (iOS and Android)$30k – $150k3 – 8 months
Complex platform or SaaS$120k+6 – 12+ months

Costs people forget

  • Hosting and infrastructure: cloud usage grows with your users.
  • Third-party services: email, SMS, maps, payments and AI APIs all charge per use.
  • Maintenance: plan roughly 15–20% of build cost per year for updates, security patches and bug fixes.
  • App store fees and compliance: developer accounts, audits and legal reviews.

How to reduce software development costs

  1. Build an MVP first. Launch the smallest useful version, learn, then expand. See our guide to building an MVP.
  2. Prioritise ruthlessly. Separate must-haves from nice-to-haves.
  3. Choose the right platform. Read web app vs mobile app before committing to two apps.
  4. Keep requirements stable inside each sprint. Late changes are expensive.
  5. Invest in discovery. A week of planning saves months of rework.

How to get an accurate estimate

Share your goals, users, must-have features and any systems you need to integrate with. A good development partner will run a short discovery phase and return a scoped estimate with a timeline, not just a number. That is how we work at Prominetix: see our software development services or request a free estimate.

Frequently asked questions

How much does custom software development cost?

It depends on scope, complexity, integrations and team. Simple apps can start in the low five figures, while complex platforms run well into six figures. A discovery phase gives you a reliable estimate.

Why is custom software more expensive than off-the-shelf?

You pay upfront for something built around your workflow, but you avoid per-seat licence fees and own a tool that fits your business exactly.

How can I reduce software development costs?

Start with an MVP, prioritise features ruthlessly, reuse proven components and keep requirements stable during each sprint.
