Best payment platform (UK) to integrate with Quickbooks

Hi,

We are taking over a sole trading equestrian business and will need to take payments on a card machine as well as having the option to receive payments over the phone.

I have looked at different options;

XLN - good transaction costs, no integration

Stripe/Square/Zettle/SumUp - higher transaction costs but an option to integrate with accounting software through an intermediary app (additional per month costs).

As we understand it the business isn't profitable and income is seasonal, but it supports another business that we will also have (accommodation). I want to keep the costs down and make sure it all runs smoothly.

Can anyone suggest a simple, cost effective system that can integrate well with Quickbooks?

Thanks for your help :)
