Compare providers on support, ownership, security and delivery process—not just the initial quote.
Ask a potential vendor to explain how they turn your requirements into milestones, who will do the work and how you will review progress. Request examples of similar projects and speak to a customer if possible. A good proposal should make assumptions, exclusions and ongoing costs easy to understand.
Key considerations
Clarify who owns the source code, design files and business data, and how you can receive them if the relationship ends. Ask how backups, access control, updates and incident communication are handled. Find out what support is included after launch and how additional requests are estimated.
Putting it into practice
Finally, notice how the vendor listens. A dependable technology partner asks questions about your operations and explains trade-offs in plain language rather than promising that every feature is easy.
