CBD seems to be everywhere lately, appearing as an ingredient in everything from dog treatments to fast food burgers. However, at least one payment processing service hadn’t caught up to the trend — until now.

The financial services company Square has started a pilot program to accept payments for select CBD products, according to Forbes. A Square spokesperson called it an “invite-only beta” in a statement to Mashable, but didn’t provide specifics beyond that.

Square’s support website specifically calls out marijuana and “related products” as things it won’t sell because they are not legal at the federal level, which should explain its previous hesitance to process CBD sales.
