A number produced without questions is a bad sign. An experienced provider returns questions first: about integrations. A provider that commits to a figure before understanding the scope is probably pricing a guess, ai automation services and that guess resurfaces as a change order — and you will pay for it.
Be wary of a gap difference between livewire and react the engineers on the sales call and the developers actually assigned. Ask for specific people rather than roles in the contract, with a provision covering replacement. A vendor that only offers a pool of resources and will not commit to individuals is preserving its own flexibility at your cost.
Ask for access to the repository from the first week. A partner that shows code only at milestones is inviting you to take delivery on faith. Daily commits tell you who is really on the project far better than a weekly report. The same holds for the automated test suite: if it does not exist, promises about quality remain just talk.
Ambiguous contract language around IP is not an accident. The document should state plainly that all outputs produced under it become the property of your business on payment. Check also which country’s law applies and the payment schedule: heavy prepayment with no deliverable attached eliminates any leverage you would otherwise keep.
Last, pay attention to how they communicate. Establish how much working-time overlap you will share each day, which named person answers day-to-day questions and how quickly. Some genuine overlap generally works; zero overlap stretches every clarification into a twenty-four hour round trip. Sloppy written English in the proposal does not improve later.
