I want an Android app (APK) for internal business use (not Play Store), to help manage all operations within my company Adore Pharma. The app should include the following core features: 1. Login System Admin login and Employee login. Admin unlocks all features; Employees can only view cameras and limited panels. 2. Parties & Clients Module Add, edit, and search Parties (Buyers/Suppliers). Show all details: firm name, owner, address, mobile, GST, delivery partners, rates, invoices, payments. Add new order and mark payments as partially/fully cleared. Show overdue invoices and notify accountant. 3. Expenses Add daily expenses with photo and note. Filter by date, person, or category. Export monthly expense reports. 4. Labour Management Add and manage labour names, departments, salaries, attendance, payment history. 5. Quotes & Invoices Create custom quotes for any party (editable price fields). Convert quote → invoice with single click. Auto WhatsApp or email invoices. 6. Cameras (XMeye / RTSP) Show live cameras inside app (local Wi-Fi instant view + remote view via VPS relay). Option to switch stream quality (HD/SD). Option to name cameras by zones. 7. PA System (Future Integration) Interface to trigger Raspberry-Pi-based PA zones (not urgent for first version). 8. Mail Integration Connect Hostinger mail (IMAP/SMTP) so admin can view/send mails directly inside the app. 9. Group Chat Internal chat between admin and employees. Option to attach images or documents. 10. Document Vault Upload, tag, and view PDFs, images, or Word files. Option to mark as private or shared. 11. Dashboard Show summary: pending invoices, total expenses, labour status, upcoming payments, active orders. --- Technical & Delivery Requirements Must deliver within 15 days.
