Our experience is quite the opposite. With B2B you have less customers, and especially enterprises have a designate email address where they want the invoice to go. They don’t care about any of that in-app. And for us with just under a 100 customers it’s easy enough to generate them through our accounting software and send with mailmerge or something like that (don’t know what our financial guy uses :). We talked about building invoicing to make things less time consuming, turned out that a better overview of the plans and usage was enough for now!
