This guide shows you how to switch on the Invoice Email extension so your invoices are emailed to customers automatically. For what the extension does and why you'd use it, see Invoice Email extension: what it does.
Invoice Email sends through your company's outbound email, so make sure email is set up in NexerIQ first (Settings → Email). If you can already send email from NexerIQ, you're ready.
There's nothing to configure — Invoice Email works out of the box using your existing outbound email and the customer's email address on record.
Once enabled, it works on its own. Each time you post an invoice, NexerIQ generates the PDF and emails it to the customer automatically. To make sure delivery succeeds:
To pause automatic emails, open the card and click Disable — your settings and history are kept, and you can re-enable any time. To remove it entirely, click Uninstall and confirm.
Tip: enable Invoice Email after you've confirmed a test email sends correctly from NexerIQ. That way the very first real invoice goes out cleanly.
