With reference to your question, I understand that you have products in Salesforce, those products contains colon in theproduct name. QuickBooks uses the colon punctuation to differentiate between the product hierarchy like parent product and child product. So we will not be able to sync products which contains colon in product name without hierarchy into QuickBooks. If your DBSync instance has been customized to implement this functionality then there will be no issues, else kindly get in touch with us and we will be able to help you with this.
