Look first at relevant experience, not the number of logos on the website. Ask for three or four case studies that resemble your technology stack, difference between laravel and node js then ask whether those engineers are still with the software development company in dubai. A serious vendor will put you on a call with the people who would work on your project. Vague answers at this stage almost always mean you are talking to a reseller.

The paperwork deserves a slower read than the pitch. Three clauses do most of the work: assignment of intellectual property, the NDA, and exit terms and handover. Everything produced should transfer to you once invoices are settled, together with documentation, pipelines and deployment scripts. Look closely at wording that leaves reusable components with the vendor, since that is often the part you cannot replace later.

Find out how the estimate was built. A serious estimate arrives with a list of assumptions, a breakdown per feature and an explicit range. A fixed-bid deal only makes sense when the requirements are stable and documented; otherwise the provider prices the risk in and you fund the buffer regardless. A time-and-materials model shifts that risk to you, so it demands visible weekly reporting and a spending cap.

How the work is run matters more than the number of developers. Establish how change requests are handled, who writes the acceptance criteria and what the QA setup looks like. A well-run team can show you running moscow software development agency rather than status reports. Written acceptance criteria are the only reliable protection against an argument at delivery time.

Last, consider the handover while the relationship is still good. Ask that the source repository sits on infrastructure you own from the first commit, and that documentation is updated as part of the work. A vendor with nothing to hide accepts it without argument; hesitation here says most of what you need to know.
