The full answer
Creuto does not give ballpark prices from a one-line description, because two apps with the same name can differ in cost many times over. The fastest path to a real number is to give the team enough to scope: who uses the product, what they must be able to do in the first release, and what it connects to.
Useful inputs include a list of user roles, the main journeys, any designs or wireframes, examples of comparable products, systems to integrate such as a payment gateway, ERP or CRM, the platforms you need (web, iOS, Android) and regulations that apply, such as GDPR, HIPAA, PDPL or DPDP. A rough budget range and target date help the team propose a scope that fits.
The discovery session is where priorities get set. Creuto will suggest what belongs in the first release and what can wait, which usually lowers the initial quote without weakening the product. Everything is written down so the proposal reflects a scope both sides understand.
The proposal itself is specific: what is built, in which milestones, by when and for how much, with payments tied to milestones. If you need the quote for a board or investor deadline, say so on the call and the team will work to it. An NDA can be signed before discovery on request.
