A number produced without questions counts as a warning, not a service level. A competent team returns clarifying questions before any number: about integrations. A provider that prices with no clarification is probably pricing a guess, and a guess will be corrected later — at your expense.
Look out for a mismatch between the team in the pitch and the people who will code. Request specific people rather than roles in the contract, with wording that requires notice before anyone is swapped. A provider that will only describe abstract roles and refuses to name individuals is keeping the right to assign anyone it likes.
Require commit-level visibility from day one. A team that hands over code only at milestones is inviting you to trust a black box. Visible commits show you who is really on the project far better than a weekly report. This extends to the CI pipeline: if nothing runs automatically, quality claims remain nothing more than words.
Ambiguous phrasing around intellectual property is rarely an oversight. The contract should state in plain terms that all outputs produced under it transfer to your business on payment.

Finally, look at how they communicate. Confirm how much working-time overlap you will share with your timezone, technical consulting services which named person handles your questions and within what time. A few hours of overlap is usually enough; zero overlap turns a five-minute question into a lost day. Careless writing in the early emails does not improve once the work starts.
