Product ordering system Bot

Introduction

Managing product orders through WhatsApp can quickly become chaotic for businesses. Important messages get buried, order formats are inconsistent, and verifying quantities or outlet details becomes time-consuming. To tackle this issue, I built a WhatsApp Ordering Bot that introduces structure, clarity, and control into the ordering process, making it efficient for both clients and administrators.

Use Case

Imagine a store manager wants to place an order. They simply send !order in their WhatsApp chat or group. The bot responds with a structured template that looks like this:

!order
Outlet Name:
Product1 x
Product2 x
Product3 x

The manager fills in the quantities and outlet name, sends it back, and the bot logs this order under their name or group. Later, the admin sends !print to get a summary of all orders for that day. This prevents mistakes, missed messages, or repetitive confirmation texts.

Workflow Overview

Client: Sends !order → Receives order template → Fills & sends
Bot: Stores order under outlet/client/group
Admin: Uses commands like !print, !cancel, !clear to manage orders

The bot distinguishes between admin and client commands, ensuring only authorized users can access sensitive functions like modifying or printing all orders.

Technology Stack

This WhatsApp Ordering Bot was developed using Node.js and is hosted on a local server. Data is stored and managed through local files, allowing the bot to quickly access and modify order data. This architecture was chosen for fast prototyping and flexibility, especially for testing in controlled environments before cloud deployment.

Client Commands

!order: Start an order. The bot sends a template to fill in product quantities and outlet name.
!update: Overwrite the current order for the same outlet with new quantities.
!check: View details of your submitted outlet order.
!cancel: Cancel your current outlet order.
