Currently using SumUp to take card payments in-person when I need to.

I've spent the past three weeks trying to get any sort of response out of support, to change the business type to the Ltd Co (something I need to do before the first MTD deadline). No dice.

So it looks like I'm closing the SumUp account before the deadline.

Any personal recommends for a (non-useless, low-volume) UK card payment system please with PoS card machine? Extra points if it'll handle invoice payment too.
