I’m looking for a skilled team that can craft an integrated ERP ecosystem to make our poultry trading operation completely paperless and fully transparent, from farm gate to final payment. Scope in a nutshell • Sales & Collection Apps – Android, built for field staff with Tamil/English labels. Must work offline, sync when connectivity returns, let users scan QR codes on crates, and attach quick voice-note updates on each visit. Geo-tag every transaction so head office can trace routes. • Customer App – Android and responsive Web front end so retailers can place daily orders, review live ledger balances, and pay instantly through UPI deep links. • Web ERP – Browser-based admin portal that shows live sales, purchase, stock, and collection dashboards, plus basic CRM tracking. • Super-Admin (SaaS) Panel – One console to spin up new companies, manage roles, limit user access, and brand each tenant separately. Essential integrations – WhatsApp Cloud API to push invoices, payment reminders, and ledger summaries automatically. – Automated PDF / Excel ledger sharing. – GPS capture for each field entry. – UPI & QR code generation for one-tap payments. Deliverables 1. Source code (I’m flexible if the stack is robust and maintainable). 2. Structured database schema and migration scripts. 3. REST/GraphQL APIs with token-based security. 4. Deployment guides for Play Store, web server, and cloud database. 5. Two rounds of post-launch refinements and a brief hand-over training session. Success criteria • All critical flows—order capture, collection entry, ledger update—must complete in under three taps. • Sync conflicts handled gracefully; no data loss when switching networks. • Admin can see real-time P&L and outstanding amounts without exporting sheets. • Field staff can operate the app entirely in Tamil if preferred. If you’ve delivered end-to-end ERP or logistics apps before and can commit to a staged rollout (MVP in eight weeks, full release in sixteen), let’s discuss your approach, tech stack suggestion, and milestone plan. ALL INCLUSIVE COST MAXIMUM WOULD BE 2,00,000 + 10% project cost for maintenance (which includes, bug fixing, MINOR modifications asked, SAAS management like changing logos or report changes, API maintenance. )
