How to use different VAT in payments

I was delivering a guest harbour payment system (based on Blippa) when I realised that the Swedish VAT for guest moorings (=parking places for boats) differs from the VAT for recreational vehicles (RVs)…

So, we had to figure out how to separate this in the payments and the reports…

But, as always, there is a Blippa solution for everything!

I could then use the custom field in the VAT calculation by enabling Custom Data in the Form and adding a custom field to each payment item.

Blippa Rules!

Note: The VAT calculation uses . instead of ,
