  Hi there, error code 6140 from QBO usually means that an invoice is rejected because we're trying to specify an invoice number that is already in use. Depending on the context, there are a couple of ways we can try to fix this:
  
  1. We could look to introduce an invoice numbering prefix to the eCommerce data to differentiate it from pre-existing invoices in your QuickBooks. For example. if you are selling on Shopify we can add a prefix "SH", so that order number "1234" would appear as invoice number "SH1234" in QuickBooks.
  
  OR
  
  2. Assuming that you have set up your QuickBooks to automatically generate new invoice numbers, we can enable the Automatic Invoice Number setting in your integration configuration. This would disregard the order number coming from your eCommerce, and allow your QuickBooks to choose the next available invoice number.
