Begin with relevant experience, not the length of the client list. Ask to see three or four case studies that match your stack, and then ask specifically which engineers actually built it. An honest provider will introduce you to the engineers. Evasive answers at this stage almost always mean you are talking to a reseller.

The paperwork deserves more attention than the sales deck. Three clauses do most of the work: ownership of the code, confidentiality, and termination and handover. All the work product should transfer end to end project development you as it is paid for, together with documentation, pipelines and deployment scripts. Watch for language that leaves so-called reusable libraries outside the transfer, as that is often exactly the piece that locks you in.

Ask where their numbers come from. A serious estimate comes with a written set of assumptions, a breakdown per feature and a best case and hire laravel expert a worst case. A fixed-price contract works only when the specification is complete; when the scope is still moving the provider pads the number and you pay for uncertainty either way. Time and materials puts the risk on your side, so it needs visible weekly reporting and a spending cap.

How the work is run matters more than team size. Ask what happens when the scope changes, who writes the acceptance criteria and how testing is organised. A team will be able to demonstrate a working build every one or two weeks. Written acceptance criteria are the only reliable protection against endless rounds of rework.

Last, think about the handover before it becomes urgent. Require that the code repository sits on infrastructure you own from the beginning, and that the documentation is refreshed in every sprint. A provider confident in its own work says yes immediately; a long negotiation over it says a great deal.
