I would like to request the ability to send invoices directly through WhatsApp, similar to the existing SMS and email delivery options.

Desired functionality:

Send invoices directly to a customer's WhatsApp number

Share PDF invoices and proposals through WhatsApp

Include invoice links, payment links, and attachments

Track delivery and message status

Use customizable WhatsApp message templates

Send reminders and payment follow-ups via WhatsApp

Support both individual and bulk invoice sending

Since WhatsApp is widely used for business communication, this feature would improve customer engagement, increase invoice visibility, and provide a convenient alternative to email and SMS.

Thank you for considering this enhancement.
