QuickBooks allows 3rd party applications to integrate with QuickBooks through SDK programming. Integration with QuickBooks will help save time, reduce data entry, and increase accuracy so you can focus on more important activities, like growing your business.

Data transfer is much more secure than manual importing and exporting, and QuickBooks validates the shared data. Some applications may be able to run even when no one is working in QuickBooks.

Below are some suggestions that will help initialize the integration between your 3rd party application and QuickBooks.

• Log into QuickBooks as the administrator (admin) user
  
• Log into your 3rd party application as an admin user (If you have the option)
• Stop hosting multi-user access, if hosting
• Switch to Single-User Mode, if in Multi-User Mode

After you get your 3rd party software to integrate with QuickBooks restart hosting, if it was stopped and return to Multi-User Mode, if user mode was changed.
