Why can't I put in more than 71 invoices?

Hello Barieplumber33

There is no limit in QuickBooks Online with regards to the amount of invoices  you can have in the product. Are you getting an error message when adding a manual invoice in the sales/customer section after having already entered invoices or are you importing invoices from a CSV?

If you can let us know the error message you are receiving we would be grateful
