Hi ena64 - thanks for the question.
In the browser version, the invoice entry screen shows the customer’s billing address when you select them. The delivery address is entered separately as the customer’s Shipping address. Go to Contacts > Customers, open the customer, and add the address there.
To check that the shippping address is showing, open the invoice, select Share > Print PDF or Download PDF, choose the PDF template, and click Preview.
You can find more information in Adding customers and Creating customer invoices.
A separate delivery docket or packing slip isn’t currently available to print from the browser version. You’ll need to use the desktop version for that, or attach your own delivery document to the invoice.
I hope this helps!
Adrian
