Invoicing software that works with Belgian banks and is modern?

I've been trying out a few different invoicing softwares, Freshbooks looks good, works fast but it's from the US so it doesn't work together with Belgian banks or bookkeeping systems, Bill-it works with Belgian banks but it doesn't look very good, the invoices look old and it's a hassle to change the layout.

What invoicing, expenses software do you use?
