Choosing a development company is simultaneously a vendor, team, and architecture decision. An agency may sell the project with senior people and quietly hand delivery to a team you never met. Evaluate not only what the company built, but who built it, how decisions were made, and how responsibility works when plans change.
Meet the people doing the work
Ask to meet the technical lead and the engineers responsible for most of the code. Clarify outsourcing, concurrent project load, and incident ownership. A capable account manager helps communication, but should not become a wall between you and engineering.
Listen to the questions they ask
A strong discovery call covers users, the current workflow, success metrics, business constraints, and risk. If the conversation immediately becomes a list of frameworks and cloud services, the team may be selling technical capacity before understanding the outcome.
Demand working software every week
Ask to see an example weekly update: a live build, completed outcomes, blockers, and decisions required from you. A Jira screenshot is not a demo. Weekly working software exposes misunderstandings in week two instead of month five.
Protect ownership and portability
Your company should own the repository, cloud account, domain, analytics, app-store accounts, and intellectual property from day one. Full access and handover terms belong in the agreement. Otherwise, changing vendors becomes expensive and risky.
Understand scope changes
Change is normal. The process should be explicit: describe the change, show cost and schedule impact, obtain approval, then build. Without that loop, fixed-price work turns into conflict or surprise invoices.
Plan for production ownership
Ask about monitoring, backups, incident response, security patches, and knowledge transfer. A product without a clear owner after launch degrades quickly. Maintenance should be a defined operating model, not a vague promise to stay available.
Red flags
Watch for a quote with no exclusions, guaranteed dates before discovery, refusal to provide repository access, a portfolio the team cannot explain, or pricing dramatically below the rest of the market. Any one may have an explanation; several together are a reason to pause.
