What custom software actually costs in 2026

Ask five agencies to quote the same project and you'll get numbers from $30,000 to $150,000. Nobody explains why, so most buyers assume someone is lying. Usually nobody is — the quotes describe five different projects hiding under one sentence of requirements. This article gives you the real ranges, the reasons they move, and the questions that make quotes comparable.

The honest ranges

For a senior US-based team in 2026, these are the bands we see across the industry when businesses pay for builds up front. Keep them in mind — they're the alternative you're comparing anything else against.

• Internal tool or focused MVP: $18k–$40k, 6–10 weeks
• Customer-facing web platform with integrations: $40k–$90k, 8–14 weeks
• Mobile app (iOS + Android): $25k–$80k, 8–16 weeks
• E-commerce replatform or ordering system: $20k–$80k, 6–12 weeks
• AI feature or automation on existing systems: $15k–$70k, 4–10 weeks
• Complex, regulated, or multi-system platforms: $100k–$400k+, 4–9 months

What actually moves the number

Five variables explain most of the spread between quotes. When you change one of these, you are not adjusting the same project — you are pricing a different one.

• Integrations: every external system (EHR, ERP, payment processor, legacy database) adds discovery, error handling, and testing. Two integrations versus six can double a build.
• Compliance: HIPAA, SOC 2, or PCI environments add roughly 20–35% for audit logging, encryption controls, and review cycles.
• Platforms: web only, or web plus native mobile? A second platform is rarely free even with shared code.
• Data migration: moving ten years of records out of a legacy system safely is often a project inside the project.
• Who you're hiring: a senior US engineer, an offshore team, and a freelancer aren't the same product. All three can be right — but their failure modes and rework costs differ enormously.

The cost nobody quotes: year two

Software is not a purchase; it's an operating asset. Budget 15–20% of the build cost per year for maintenance — dependency updates, OS releases, security patches, and the steady stream of small improvements that keep the product matching your business. A vendor who never mentions this is planning to disappear after launch, or planning to charge you emergency rates when something breaks.

The good news: maintained software compounds. The clients who spend that 15% see their cost-per-feature drop every year, because a healthy codebase gets cheaper to change, not more expensive.

How to make quotes comparable

Before comparing prices, force the quotes to describe the same project. Send every vendor the same one-page brief: the workflows in scope, the systems to integrate, the compliance context, and the platforms. Then ask each one three questions: What's excluded from this number? What happens if it runs over? What does month thirteen cost me?

The cheapest quote with vague answers to those questions is usually the most expensive project in the room.

How we broke the model

We stopped charging for builds altogether. At 714software, scoping is free, the build is free, and you don't pay anything until your finished product is delivered and running — then services start from $35 a month. The industry ranges above are what makes that trade worth understanding: instead of writing a five-figure check and carrying all the risk, you pay nothing until the thing works, and the risk sits with the people building it.
