Send invoices, receipts, payment reminders, order confirmations, and reservation reminders via WhatsApp. Customers respond on the channel they already use daily.
Settings → Integrations → WhatsApp Business. Click Connect. Scan QR with the phone running your WhatsApp Business account.
Send a test message from the integration page to your own number. Confirm it arrives.
Per surface — Invoices / Receipts / Payment reminders / Order confirmations / Reservation reminders — pick WhatsApp (instead of or alongside Email/SMS).
Edit the message template for each event type. Use placeholders like {customer_name}, {invoice_link}, {amount}.
Replies land in Settings → Conversations so any team member can respond. Avoids the "WhatsApp message stuck on one person's phone" problem.
