Send to Whatsapp Feature Request.
Many of the accounting software platforms now have this option. For me it would be useful as many of my customers are using this method to communicate. Some of them seem less inclined to check their email accounts regularly which can result in them missing my invoices. If I could send to whatsapp and/or email maybe this would save me chasing payments. Perhaps this feature could be added to individual contact details and pop up in the send invoice section?
