What drives the cost

• Number of user roles and permissions (admin, staff, customer, partner)
• Number and complexity of workflows, screens and business rules
• Integrations with payments, accounting, ERP or other third-party APIs
• Migrating data from spreadsheets or an existing system
• Reporting, dashboards and analytics
• Security, hosting and compliance requirements
• Design effort and how polished the interface must be
• Timeline: very short deadlines usually cost more

Fixed price or hourly?

Fixed price suits a clearly defined scope. Hourly or weekly billing suits projects where requirements will evolve as you learn from users. A good middle path is a small, clearly scoped first version at a fixed price, then weekly increments as the product grows.

How to keep the budget under control

• Start with the smallest version that solves your most expensive problem (an MVP)
• Separate must-haves from nice-to-haves and build the must-haves first
• Review working software every week so wrong turns are caught early
• Agree changes to scope explicitly and re-estimate before building them
• Choose a widely used stack so future maintenance stays affordable
• Plan for hosting, maintenance and support, not only the first build
