WhatsApp Messaging

Talk where your customers are

Send invoices, receipts, order updates and payment reminders on WhatsApp from your own business number, alongside Bigz SMS from your own gateway.

WhatsApp & SMS
WhatsApp & SMS — Invoices, receipts, payment reminders, low-stock alerts and the daily summary go out on WhatsApp or SMS.

Link your business's own WhatsApp number by scanning a QR code. Then choose which messages go out on their own — a sale, a receipt, a quotation, a web order update or an overdue reminder — and word each one your way.

Messages always come from your own number. Every message is logged, including why one wasn't sent, practice documents are never sent, and you can send any document by hand in one tap.

Questions

How do I start sending SMS, WhatsApp and email?

Connect your own accounts in settings: scan a QR code for your WhatsApp number, enter your SMS gateway details from any provider, and add your business email's SMTP details, then press Send test email. The setup checklist shows what's connected, and every message is logged, including why one wasn't sent.

How do I connect my WhatsApp number to biGz CRM?

Scan a QR code from your phone, then add your website, price sheet or FAQ to teach the AI and switch on the AI sales assistant flow.
