## The challenge

A growing e-commerce operator needed customers to pay via Telegram without leaving the chat. They required support for Bangladeshi mobile banking (bKash, Nagad) and international crypto, with admin verification and automatic order updates.

## Our solution

BDBOTS built a Telethon-based payment gateway bot that guides users through checkout, captures transaction IDs, and routes submissions to an admin review queue. Confirmed payments trigger invoice updates and customer notifications automatically.

## Key features

- Multi-method payments: bKash, Nagad, Binance USDT, BEP20

- Admin dashboard for approve/reject with audit trail

- Duplicate reference detection and fraud safeguards

- Customer receipts and order status in Telegram

## Results

Payment verification time dropped from hours to under 30 minutes on business days. The client processes 200+ transactions monthly through the bot with 99.9% uptime on BDBOTS hosting.
