The tools you already pay for should talk to the system you run on. Connections now live on one page with a clear status on each.
WhatsApp Business
Connect your WhatsApp Business account and see its status, so you know whether messages will actually send before you rely on them.
Stripe for Payments
Your Stripe account connects from the same page, which is what puts card and local payment methods on your website and at your counter.
Xero for Accounting
Xero appears alongside them, laying the groundwork for sending invoices and payments to your accounts rather than re-keying them.
