I’d like Dext to read all purchases, identify any supplier with a foreign currency and apply a tax rate. I don’t want the supplier to be the determining factor. Let’s say that a client is on a work trip in France, there will be a number of purchases from various suppliers over the course of the trip, so we wouldn’t setup supplier rules because it’s unlikely that they’ll use the same restaurants again, especially if the trip is a one-off. But, all of the purchases will be reverse charge regardless of the supplier. Therefore, I’d like Dext to ignore the supplier condition and have a forex rule that says “if any purchases in forex” then apply reverse charge as a rule.
