Turning WhatsApp Into a Mobile ERP for Field Logistics (Apps Script + Google Sheets)

The MageSheet team built a mobile ERP for field logistics by integrating WhatsApp with Google Sheets via Apps Script. Drivers text status updates, which are parsed by an LLM and recorded in real time, achieving 90%+ adoption. The system handles multilingual input and runs on free Google Workspace infrastructure.

Field-service software has an adoption problem: drivers won't use it. Heavy app, another login, crashes in low-signal areas. So the "real-time" data still shows up as end-of-shift phone calls. The fix that actually sticks: stop building an app and use the one drivers already live in — WhatsApp. With Apps Script and Google Sheets behind it, WhatsApp becomes a frictionless mobile ERP. Here's the build. A driver texts Status ABC-1234 Delivered . An Apps Script doPost webhook receives it, parses it, and updates the Sheet in real time. Latency goes from hours to milliseconds — and there's nothing to install, so adoption hits 90%+ in a week vs. 50–70% for custom apps . Real drivers type "done," not clean commands. So: Below-threshold messages surface to a dispatcher. The LLM normalizes correctly 95%+ of the time ~5% manual , and it handles multilingual input with zero extra code. Driver msg → Apps Script doPost → regex pass → fail LLM fallback w/ confidence score → Sheet update timestamp + raw-message log → optional outbound route change, POD photo request It runs on free Google Workspace infrastructure with minimal API cost. The same integration pushes messages back to drivers: route changes, delivery instructions, shift reminders, exception alerts, proof-of-delivery photo requests — all in the same thread. The full guide details the five that matter: unofficial WhatsApp libraries ban risk , missing opt-in workflow, no multilingual support, no raw-message audit log, and no offline/out-of-order resilience.
