Begin with domain experience, mvp development company not the size of the portfolio. Ask for two or three engagements that match your domain and your stack, and then ask who actually wrote that code. A solid partner will introduce you to the tech lead. Evasive answers at this stage usually mean the delivery team is not the team you were shown.

The contract warrants a slower read than the pitch. Three sections matter more than the rest: ownership of the code, confidentiality, and termination and handover. Every artifact must transfer to you on payment, including documentation, pipelines and deployment scripts. Look closely at language that keeps so-called reusable libraries with the vendor, as it is usually the dependency that makes switching painful.

Ask how they estimate. A serious estimate comes with a list of assumptions, a task-level breakdown and a range rather than a single number. A fixed-bid deal only makes sense when the specification is complete; otherwise the vendor prices the risk in and you pay for azure software development company it anyway. A time-and-materials model puts the risk on your side, so it needs a sprint cadence, demos and a budget cap.

The delivery process beats headcount. Find out what happens when the scope changes, who defines done and how quality assurance works. A well-run team will be able to demonstrate running software rather than status reports. Acceptance criteria in writing are your only real protection against the it-was-never-in-scope conversation.

Finally, think about the handover while the relationship is still good. Require that the code repository stays in your organisation from the beginning, and that a readme and architecture notes are kept current as the code changes. A partner who is comfortable with this says yes immediately; a long negotiation over it tells you a great deal.
