1.How do we switch to another payment processor in QB POS?

2. QB info article states store exchange will no longer be supported but can be done "in the following 4 ways" but then never lists the ways...How can store exchange be done?

Shopify POS is not what we were told, assemblies cannot be transferred from QB POS...Most of our items are assemblies (almost 2,000) so if this info can't be moved to shopify POS and we have to rebuild from scratch then there's no reason for us to convert to shopify, its not the greatest and the only reason we would use it is that we were told the transition would be seamless, its not.

So now our search for a POS/inv system starts over and we want to continue using QB POS until we find a suitable replacement.

QB reported that customers can continue using QB POS with another payment processor but how is that done?

I was on the phone w/ square yesterday and they said there should be an option in preferences --> sales receipt to check a box to use square reader but its not there.
