Hi Richard,
You can download the pdf’s by going into the invoice and clicking client view there you’ll see download invoice.
Your clients can alway access the invoices as they wish, html or pdf we never interfere there.
The new updates we did on the invoicing showed that being able to access PDF invoices from everywhere was the number one request so we made it a premium feature.
Another reason is we’re trying to push people away from PDF’s. There are some new features coming out in our premium app that require the html version of the invoice. PDF’s are like sending sheets of paper in a digital world, you can’t bring any biz benefits to customers with them.
Cheers
Pete
