Thank you for the reply. I understand that POS v19 is being discontinued and fully comprehend that. 

The question's that I cannot find an answer to is 

" Will the financial exchange between POS v19 and QuickBooks Pro Desktop 2021 still work after October 3rd 2023?" 

Will the Financial exchange be taken out of the future versions QuickBooks being they are discontinuing POS v19?

As some people may choose to stick with the POS v19 program for a while whether by choice or necessity as there is no viable alternative or frankly not enough time seeing as how we were given relatively short notice.
