Why when the invoices Sync to Quickbooks it keeps making new 'product' codes with random ID numbers after every invoices is received?  I am not using different products in Thryv when i create my invoice... If this is a QB problem, please let me know. 

Thanks for your post! It is required to use the date picker to select a date for invoices and payments, in order to ensure that formatting is consistent. We can absolutely add the request for typable date in our Feedback Center where other users can vote for it

For your question about QuickBooks, can you clarify whether you are referring to QuickBooks Online or Desktop?

Can you provide a screenshot in QuickBooks of the number you are talking about so we can see what is happening?
