I am entering my credit cards under credit cards:).

Go to file--> Set up Interview --> Payment tab and select no to taking credit cards.  I know this seems counterintuitive, but you can then select credit when making a sale.  The POS then pops up choices of Visa, MC, Discover and Amex to choose from.  Doing the check thing is a great work around tho.  Mine have been batching/ reconciling easily in QB using the credit feature.

Would love to hear everyone's input on options beyond QB POS. Shopify did not seem like a good fit. I am on option 2 and hate it likely more than option 1.  Are we just all spoiled from the easy syncing of POS to QB?  I am trying very hard to make this second POS work, but it is so slow and doesn't batch out checks from the cash and soooo many other things.  I am not trusting POS 19.0 with a third party processor to be able to run my business just due to the lack of backup if something goes south.
