When the Y.E.S.!™ Accounting Interface is started, the screen shown below will appear.
Manual Updates
In normal use (once configured) all that you need to do in order to update your QuickBooks® accounting is to click on the "Manual Start" button.

Automatic Update Configuration
You can have the Y.E.S.!™ Accounting Interface automatically update QuickBooks® every day at a given time, by checking "Enable Auto Start" and selecting a Start Time on the main screen as shown above.
NOTE: For this option to work, you MUST leave the Y.E.S.! ™ Accounting Interface running on your computer. You can minimize it while it is running so that it does not interfere with other activities.
