Why Quotes Vary So Much

Ask five agencies to price the same idea and you can get five very different numbers. That is rarely about greed. Each one is guessing at a scope that has not been written down yet, and each guess fills the gaps differently.

The way to a reliable number is a clear scope, not a cheaper vendor.

What Drives the Price

Scope and Number of Screens

Every screen, form and user role adds design, build and testing time. A customer app with a separate admin panel is effectively two products.

Integrations

Payments, maps, SMS, accounting software and existing company systems each need setup, error handling and testing. Older systems with poor documentation add the most uncertainty.

Platforms

A responsive web app runs everywhere from one codebase. Native iOS and Android apps add app store work and device testing. Cross-platform tools such as React Native close much of that gap.

Quality Requirements

Security reviews, accessibility, high availability and audit logs all take real effort. They are worth it, but they should be decided up front, not discovered late.

Where the Budget Goes

A typical project splits roughly like this:

  • Discovery and planning, around 10%
  • UI and UX design, around 15%
  • Development, around 50%
  • Testing and quality assurance, around 15%
  • Launch, handover and early fixes, around 10%

Skipping discovery or testing rarely saves money. It moves the cost to after launch, where changes are slower and more expensive.

Fixed Price or Time and Materials?

A fixed price suits a small, well-defined first version. Time and materials suits products that will change as you learn from users. Many teams combine the two: a fixed-price discovery phase, then monthly sprints.

How to Keep Costs Under Control

  1. Write down the problem and the users before listing features
  2. Cut the first release to what proves the idea
  3. Use proven services for payments, email and login instead of building them
  4. Ask for a demo every one or two weeks
  5. Budget for hosting, support and updates after launch

Conclusion

Custom software is an investment, and like any investment it pays back best with a clear plan. A short discovery phase is the cheapest way to get a quote you can trust.
