I need a mobile app developed for both Android and iOS platforms to streamline the onboarding process for our channel partners. The app must allow partners to complete their full KYC, which would require them to both upload necessary documents as files and fill out a detailed form. The app should also enable us to send push notifications directly to the partners. Additionally, the app should integrate with our current live inventory, which is maintained on Google Sheets, allowing partners to view inventory updates in real-time. They should also be able to make sales offers directly from the app, with all transactions and offers being properly recorded within the system. If you are interested, please include detailed project proposals in your application, outlining your approach to building the app and any relevant expertise you bring to the table.
