Looks good! Thanks for sharing.
Shameless plug, but here in the UK we built Penny, which is an invoice factoring tool (U.K. only), i.e. You sell us your £1000 invoice that’s due in thirty days and we’ll buy it off you at a discount and pay it the next day.
We don’t have invoice templating but it’s a nice to have.
I’m still trying to crack the easiest way to reduce friction in entering enough but minimal data for us to be able to generate a usable invoice. Tough cookie to crack
