A quote that comes back within a day counts as a bad sign. A competent team returns questions first: about users and volumes. A vendor that quotes before understanding the scope is simply working from a template, and that guess resurfaces as a change order — on your budget.
Look out for any distance between the team in the pitch and the people who will code. Request specific people rather than roles in the agreement, with a clause that requires notice before anyone is swapped. A team that only offers roles and never names specific engineers is keeping the right to assign anyone it likes.
Require the source repository from the start. A provider that shows nothing between demos expects you to trust a black box. Daily commits reveal the actual pace far better than any status report.
