How to Select a Software Development Partner: What to Check Before You Sign > 선물셋트

Start with proven experience, not the number of logos on the website. Ask react developer for hire two or three projects that match your domain and your stack, and then find out who actually wrote that code. A solid partner will introduce you to the tech lead. Vague answers at this stage usually mean the demo work came from somewhere else.

The contract deserves a slower read than the pitch. A few clauses carry most of the weight: assignment of intellectual property, non-disclosure, and termination and handover. Every artifact should transfer to you as it is paid for, including documentation, pipelines and deployment scripts. Look closely at any clause that keeps reusable components with the vendor, as this is frequently exactly the piece that locks you in.

Ask how they estimate. A credible estimate arrives with a written set of assumptions, a task-level breakdown and a range rather than a single number. A fixed-price contract only makes sense when the requirements are stable and documented; when the scope is still moving the supplier adds a risk premium and you fund the buffer regardless. Time and materials puts the risk on your side, so it requires a sprint cadence, demos and a budget cap.

How the work is run matters as much as headcount. Find out what happens when the scope changes, who signs off on a feature and difference between rest and graphql how testing is organised. A mature team should be able to show you a live build at the end of each sprint. Clear, written acceptance criteria are the practical protection against endless rounds of rework.

Last, think about the day you no longer need this vendor while the relationship is still good. Require that the source repository stays under your account from the beginning, and that documentation is written as you go rather than left to the end. A provider confident in its own work says yes immediately; resistance at this point tells you a great deal.
