@mightyd3 do you sell a SuiteApp or do you come in and build something custom? I have a client that's looking for a solution ready for Germany and Belgium outbound e-invoicing; and maybe taking inbound away from Zone & Co. Would love to hear more about what you do.

Both, but have nothing in that space.

Assuming you're OK with peppol gateway integrations, the rest is just serialising invoice records into whatever format is required in each country?
