Begin with domain experience, not the size of the portfolio. Ask for a couple of projects that resemble your domain and your stack, ai coding tools for development teams and then ask specifically which engineers actually built it. A serious vendor will put you on a call with the tech lead. Evasive answers at this stage almost always mean you are talking to a reseller.
The contract needs more attention than the sales deck. Three sections matter more than the rest: assignment of intellectual property, confidentiality, and exit terms and handover. Every artifact should transfer to you as it is paid for, together with designs, scripts and infrastructure configuration. Be careful with language that leaves framework code in the vendor's hands, since that is often the part you cannot replace later.
Ask where their numbers come from. A credible estimate is accompanied by a list of assumptions, a breakdown per feature and an explicit range. A fixed-price contract works only when the scope is genuinely frozen; otherwise the supplier adds a risk premium and next js vs laravel performance you pay for uncertainty either way. Hourly billing puts the risk on your side, so it needs a sprint cadence, demos and custom mobile app development services a budget cap.
The delivery process beats team size. Find out what happens when the scope changes, who signs off on a feature and what the QA setup looks like. A team can show you a working build every one or two weeks. Written acceptance criteria remain your only real protection against endless rounds of rework.
Last, plan for the end of the engagement before it becomes urgent. Require that the code repository sits on infrastructure you own from the first commit, and that a readme and architecture notes are kept current as the code changes. A provider confident in its own work accepts it without argument; hesitation here tells you most of what you need to know.
