WhatsApp Receipt Scanner Bot for Small Businesses

Published Mar 10, 2026

🔴 Problem Identified

Small businesses with field workers struggle with manual expense tracking. Workers submit paper receipts that need to be manually entered into spreadsheets by accountants or business owners, creating a time-consuming bottleneck. This is especially painful for contracting, construction, and service businesses where workers make frequent on-site purchases.

💡 Proposed Solution

A WhatsApp bot that automatically extracts vendor, amount, and date information from receipt photos using OCR technology, then logs the data directly into Google Sheets. Workers can also query the bot for balance checks and recent receipt history, streamlining the entire expense tracking workflow.
