A quote that comes back within a day is a red flag rather than good service. Any serious team will come back with a list of questions: about users and volumes. A vendor that quotes before understanding the scope is working from a template, and that guess resurfaces as a change order — and you will pay for it.
Watch for any distance between the people you meet and those who eventually appear in the repository. Insist on named engineers hire developers in moscow the statement of work, with a provision about substitutions. A vendor that will only describe roles and never names people is keeping the option to staff you with whoever is free.
Require commit-level visibility from the start. A provider that shows a build only at the end of each phase is asking you to take delivery on faith. Regular commits and pull requests reveal the actual pace far better than any status report. This extends to the CI pipeline: if it does not exist, promises about quality remain nothing more than words.
Loose phrasing around IP is not an accident. The document must state explicitly that all deliverables become the property of your online store development company on payment. Also check the governing law and php development services the payment schedule: a request for most of the money up front with no milestone tied to it eliminates the only leverage you have.
Last, look at communication. Ask how many hours the .net dedicated teams will share with your timezone, who is expected to answer questions and on what response times. Four hours of overlap is usually enough; none at all converts a five-minute question into a twenty-four hour round trip. Sloppy written English in the sales phase will not improve later.
