Android GST Billing App Development

Job ID: 40274355

Budget: ₹1,500 – ₹12,500 INR

I need a cloud-connected Android application that lets me handle GST billing from end to end. The core workflow must cover invoice generation, accurate tax calculation and a simple client database, all stored securely in the cloud so data stays synced across devices.

Beyond those basics, I also rely on:
• Inventory management tied directly to sales and purchase entries
• A built-in payment gateway so customers can settle invoices instantly
• Clear reporting and analytics dashboards (sales, tax collected, stock levels, etc.)
• Ready-to-export GST filing formats to speed up my monthly returns

The interface should be clean and fast, working smoothly on current Android versions. I will need full source code, deployment to the Play Console, and a short hand-off session that walks me through adding new tax slabs or report templates later. If you have prior experience with similar finance or POS apps, please mention it when you respond—seeing real examples will help me move quickly on awarding the project.
