Buyer notes
Start with the work, not the sales deck. Ask each company to show a project that faced similar technical, budget, or delivery constraints.
Meet the people who will do the work. Confirm how scope changes are handled, what the reporting rhythm looks like, and which deliverables you own at the end.
Common questions
Compare work that matches your project, the people assigned to the account, ownership of deliverables, communication routines, pricing terms, and what happens after launch.
No. Many companies use distributed teams. Ask where your delivery team is located, who leads the work, and which time zones are covered.
Use it as a starting point for a shortlist. It reflects visible proof, service fit, company history, and relevance to US buyers. It is not a customer rating or a guarantee.
Ask for relevant case studies, working product links when available, references, delivery plans, team details, and a written estimate that explains assumptions.
Fixed pricing can suit a clearly defined scope. A dedicated or time-based team is often more practical when requirements will change during discovery and delivery.
Three to five is usually enough. A smaller shortlist gives buyers time to compare the actual team, process, commercial terms, and quality of the proposed plan.
