These tools are designed to help businesses automatically send WhatsApp messages to their customers for key events such as order confirmations, logins, invoice reminders, and support updates — without writing a single line of code.
Our WhatsApp plugins are easy to install, beginner-friendly, and built with flexibility in mind. Whether you’re running an online store with WooCommerce, managing a hosting business with WHMCS, or simply want to connect with your customers more effectively, we’ve got a solution for you.

💬 WhatsApp Team Inbox & Online Support System
Manage all customer conversations in one place — together with your team.
With WhatsiPlus, you get a shared Team Inbox for your WhatsApp number, allowing multiple support agents to reply to customers simultaneously. You can assign chats, leave internal notes, track conversation history, and deliver real-time customer support — just like a modern helpdesk, but inside WhatsApp.
👉 No more WhatsApp Web chaos — just organized, collaborative messaging.
🔐 WhatsApp Login (Reverse OTP) – Receive & Recognize Incoming WhatsApp Messages
With Whatsiplus, you can receive and process incoming WhatsApp messages, not just send them. One of the most powerful use cases is our Reverse OTP login method — a completely secure and innovative way for users to log in without needing email or passwords.
Instead of sending OTP codes to users, your website generates a unique code and asks the user to send it to your WhatsApp number. This user-initiated message protects your number from being flagged or banned and boosts your WhatsApp credibility through real engagement.
- ✅ Passwordless, email-free login experience
- 🔁 Reverse OTP: customer sends the code via WhatsApp
- 💬 Custom automated response after verification
- 📊 Login status tracking and analytics
- 🔗 QR Code and direct link support
- 🔐 Fully integrated with WordPress and WHMCS
- 🎁 Free plugins and modules ready to download
