You don't have an on-call rotation but do have people dedicated to vendor relationships, and that guy works on the weekend? I'm not sure how you completely avoid getting alerts on the weekend for third-party payment processor issues, which can happen anytime, if you actually want to transact business on the weekend.
I said vendor here but it’s more like banks we work with. So there’s someone responsible for the technical side of banking relationships.
But yeah it’s kinda a zone where most weekends there’s no problems so it’s not a huge priority… until it is

I'm an account manager. My clients will phone at almost any time, weekends included, if they feel there issue wasn't yet looked at by the on call dev.
