Begin with proven experience, not the number of logos on the website. Request two or igaming platform sdk three engagements that resemble your stack, and then ask whether those engineers are still with the nextjs development company. A solid partner is happy to connect you with the engineers. Answers that name nobody at this stage generally mean the demo work came from somewhere else.
The contract warrants more attention than the sales deck. Three clauses do most of the work: government software development company assignment of intellectual property, the NDA, and termination and handover. All the work product has to transfer to you on payment, together with documentation, pipelines and deployment scripts. Be careful with language that leaves reusable components with the vendor, as it is usually the part you cannot replace later.
Ask how they estimate. A serious estimate is accompanied by a list of assumptions, a task-level breakdown and a best case and a worst case. A fixed-bid deal only makes sense when the scope is genuinely frozen; in any other case the vendor prices the risk in and you pay for uncertainty either way. A time-and-materials model puts the risk on your side, so it demands a cap, regular demos and transparent reporting.
Process matters more than the number of developers. Establish what happens when the scope changes, who writes the acceptance criteria and how quality assurance works. A mature team can walk you through a working build every one or two weeks. Acceptance criteria in writing remain your only real protection against the it-was-never-in-scope conversation.
Before signing, vue js development services consider the day you no longer need this vendor while the relationship is still good. Ask that the repository lives in your organisation from the first commit, and that documentation is updated as part of the work. A partner who is comfortable with this accepts it without argument; resistance at this point reveals quite a lot.
