WiFi Voucher Sales App with Google Sheets Integration

Description:
We are a hotspot business looking to develop a simple custom app that enables our sales agents to issue WiFi vouchers and log each sale. The app should connect directly to a Google Sheets backend where all voucher codes are stored and managed.

Key Features Required:

App interface for agents to:

Select voucher type (1 Day / 15 Days / 30 Days)

Enter customer name or contact

Automatically assign the first unused voucher code from Google Sheets

Voucher should be marked as “Used” with:

Timestamp

Assigned customer info

Agent info

Each issued voucher should be logged in a second Google Sheet

Agent login via PIN or simple ID

Admin dashboard or view to:

Upload new voucher codes

Monitor issued codes

Track sales activity

Preferred Tools (but open to alternatives):

Glide

AppSheet

Adalo

Custom solution if it cleanly integrates with Google Sheets

Deliverables:

Fully functional mobile-friendly app

Google Sheets integration (we provide initial templates)

Basic documentation or walkthrough for agents and admin

Support for setup and post-launch (7 days)

Optional: Add QR code for each issued voucher

Timeline:
Completion within 7–10 days from project start
