Frequently asked questions
How can I tell a good software developer?
They can show live projects with links, give a clear quote, and regularly show you a working version during development.
How do you pay a software developer?
Usually in milestones: kickoff, interim deliveries and go-live. Each payment is tied to a delivery.
Should I sign a contract with a developer?
Yes; scope, delivery dates, payment plan, source code ownership and support period should all be in writing.
Freelance developer or agency?
With a freelance developer you work directly with the person writing the code; an agency has a project manager and a team. Either can be the right choice depending on your needs and budget; what matters is references and a transparent process.
