Quick answer
To choose a software development company, assess how well they understand your business problem, their relevant experience with verifiable references, who will work on your project, their process for requirements, design, testing and communication, how they estimate and handle change, code and IP ownership terms, security practices and post-launch support. Compare proposals against the same scope rather than by total price alone.
Key takeaways
- Judge understanding of your problem, not just technical claims.
- Ask who will actually work on your project and talk to them.
- Ensure contracts give you ownership of code, accounts and data.
- Compare proposals on scope, assumptions and support, not only price.
Who this guide is for
Founders, business owners and managers selecting an agency or development partner for custom software, apps or integrations.
Start with your problem, not their portfolio
Before meeting vendors, write a short brief: business problem, users, main workflows, systems to integrate, constraints and what success looks like. In early conversations, notice whether the company asks thoughtful questions about your business and challenges your assumptions, or immediately quotes technology and timelines. Good partners clarify the problem before proposing a solution, and they will tell you when a simpler or cheaper option is enough.
Check relevant, verifiable experience
Ask for examples of similar projects in complexity, domain or integration type, and request references you can speak to. Treat logos and claims cautiously unless you can verify them; some agencies display client names from minor engagements. Ask what went wrong in a past project and how they handled it; honest answers reveal more than polished case studies. Relevant experience reduces risk, but a strong process can compensate for a new domain.
Meet the people who will do the work
Sales teams and senior architects often lead the pitch, but different people may build your software. Ask who will be the project manager, lead developer and tester, how much of their time is allocated, and whether any work is subcontracted. Speak to the lead developer about your requirements. Ask how they handle team changes during the project, since staff turnover is a common cause of delays.
Understand their delivery process
Ask how they gather requirements, design user experience, plan sprints or milestones, test, demonstrate progress and deploy. Look for regular demos of working software, written acceptance criteria, automated testing for critical flows and code reviews. Ask what tools they use for project tracking and whether you will have access. A transparent process lets you see problems early rather than at the end.
Examine estimates and change handling
Good estimates list assumptions, exclusions and risks. Ask how they handle requirements that change, which they always do: fixed-price contracts need a change process, and time-and-materials contracts need budget controls and reporting. Be wary of quotes that are much lower than others without a clear reason; they often exclude testing, integrations, content, deployment or support, which reappear as extra charges.
Clarify ownership, security and handover
The contract should state that you own the source code, designs and data upon payment, and that repositories, hosting, domains and third-party accounts are in your organization’s name. Ask about security practices: secure coding, dependency updates, access control and handling of secrets. Require documentation and a handover process so another team could maintain the software if needed.
Plan post-launch support
Software needs maintenance, bug fixes and improvements. Ask about warranty periods, maintenance plans, response targets and costs for changes after launch. Consider starting with a small paid discovery or first phase to test the working relationship before committing to a large contract. The right partner is one you can work with over years, not just one project.
Scope checklist
- Did they ask good questions about your business problem?
- Can you verify similar past projects and speak to references?
- Who exactly will work on your project?
- Does the estimate list assumptions and exclusions?
- Will you own the code, accounts and data?
Frequently asked questions
What questions should I ask a software development company?
Ask about similar projects and references, who will do the work, their delivery and testing process, estimation assumptions, change handling, ownership of code and accounts, security practices and post-launch support.
Is it better to choose a fixed-price or hourly software contract?
Fixed price suits well-defined scope; time and materials suits evolving requirements. Either needs clear assumptions, reporting and change control.
How do I check if a software company is reliable?
Speak to references, review real work, meet the delivery team, examine their process and contracts and start with a small paid phase if possible.
