Shopify integrates just fine with QuickBooks Online charge/debit cards. HOWEVER, cash/check sales do not integrate into QuickBooks on-line. We have to manually enter all cash/check Shopify transactions into QBO. This has been going on for9 months and no one seems to know why. Obviously, a box needs to be checked (or unchecked) to make this work. What a pain.
Thanks for your help.
