Begin with proven experience, not the number of logos on the website. Request a couple of engagements that sit close to your domain and nodejs web development company your stack, and then ask specifically who actually wrote that code. An honest provider is happy to connect you with the tech lead. Evasive answers at this stage usually mean you are talking to a reseller.

The paperwork needs more attention than the sales deck. A few clauses carry most of the weight: ownership of the code, confidentiality, rust erp and exit terms and vue js vs react handover. Every artifact must transfer to you on payment, together with designs, scripts and infrastructure configuration. Be careful with wording that leaves so-called reusable libraries in the vendor's hands, as it is usually exactly the piece that locks you in.

Ask where their numbers come from. An honest estimate comes with the assumptions behind it, a breakdown by feature or module and a range rather than a single number. A fixed-price contract is only reasonable when the requirements are stable and documented; in any other case the vendor prices the risk in and you pay for uncertainty either way. A time-and-materials model moves the risk back to the client, so it requires visible weekly reporting and a spending cap.

How the work is run matters as much as headcount. Find out how a new requirement enters the plan, who writes the acceptance criteria and what the QA setup looks like. A well-run team will be able to show you running software rather than status reports. Acceptance criteria in writing remain your only real protection against an argument at delivery time.

Last, think about the end of the engagement before it becomes urgent. Require that the code repository lives in your organisation from the first commit, and that the documentation is refreshed in every sprint. A partner who is comfortable with this will agree quickly; resistance at this point reveals quite a lot.
