A number produced without questions should be treated as a warning, not a service level. A competent team returns questions first: about users and volumes. A vendor software development rates that prices before understanding the scope is simply working from a template, and the gap resurfaces as a change order — and you will pay for it.

Look out for a gap between the people you meet and those who eventually appear in the repository. Insist on specific people rather than roles in the statement of work, with wording that requires notice before anyone is swapped. A provider that talks only about roles and never names specific engineers is preserving the option to staff you with whoever is free.

Ask for the source repository from the start. A provider that delivers code only at milestones is inviting you to take delivery on faith. Daily commits tell you the actual pace far better than a slide deck. The same applies to the build and javascript seo agency deployment setup: if nothing runs automatically, promises about quality are nothing more than words.

Loose contract language around intellectual property is not an accident. The document should state in plain terms that all outputs produced under it belong to your company on payment. Check also which country's law applies and how payments are structured: heavy prepayment with no deliverable attached eliminates any leverage you would otherwise keep.

Last, pay attention to communication. Ask what overlap there will be with your timezone, which person answers your questions and within what time. Four hours of overlap is usually enough; zero overlap converts every clarification into a day of delay. Unclear written communication in the proposal rarely improves later.
