Requirements

To send you an accurate scope and timeline, I need to know: 1. CORE FEATURES. What does the app do? Three to five sentences describing the main user flows is enough at this stage. 2. USER ROLES. Who logs in? (customer, vendor, admin, dispatcher, etc.) If multi-tenant, how is data isolated between tenants? 3. PAYMENTS. Subscriptions, one-time charges, marketplace splits with Stripe Connect, or no payments yet? 4. INTEGRATIONS. Any third-party services already decided? (Resend, Twilio, Mapbox, OpenAI, custom REST APIs, etc.) 5. PLATFORM PRIORITY. iOS first, Android first, both simultaneously, or do you need a web build alongside? 6. APP STORE STATUS. Do you already have Apple Developer + Google Play Developer accounts ready, or is that on your to-do list? 7. TIMELINE. Hard launch date (investor demo, conference, marketing campaign) or "as soon as it is good"? 8. BUDGET CHECK. This service is fixed at $4,800 for 8 weeks. If your scope is smaller (single feature, MVP slice, audit) or larger (full team retainer), I will recommend a better-fitting service or quote a custom scope instead of forcing this one. Within 24 hours of receiving your answers, I send back: - A written scope document - Weekly milestone breakdown - Fixed-price quote you can accept or negotiate
