Simple Android POS App Build

I am creating SARAZ EASY POS, a lightweight point-of-sale application for Android that must run smoothly offline. The scope is focused and the budget is intentionally lean, so clean, uncomplicated code is essential.

Core functions
• Single-user login for the admin.
• Product catalogue management—add, edit, delete.
• Cash-only billing that instantly records each sale.
• Automatic daily sales report saved locally for later export.
• PIN-based authentication for quick entry while keeping data secure.
• A strictly minimalist UI in English so any staff member can learn it in minutes.

Timeline & workflow
I would like the first working APK in about a week, refinement in the second week, and final hand-off by day twenty. Payments will be released by milestone: initial build, feature-complete beta, and Play Store–ready bundle.

Deliverables
– Signed Android App Bundle (.AAB) ready for production
– Complete, well-commented source code
– Step-by-step guidance to upload and run internal testing on Google Play

If you value straightforward communication, honest estimates, and writing simple code that just works, this project should fit you perfectly.
