I have over 14000 credit card transaction every month to manually import, and they are imported on a daily basis. Will there be a limit to the number of single transaction that are allowed to be imported each month?
You'll be happy to know that the import function in QuickBooks Online doesn't have a limit.
However, please know that the amount of information you bring in to QuickBooks Online may affect the loading speed of the system.
