If you don't want to create your projects in QuickBooks first, you can instead create projects in BigTime and export them to your organization's QuickBooks file. To do so, first follow this article to create a new project, or navigate to your project list and click on the name of your chosen project. Then, go to the Details tab in your project’s dashboard.
If the project in question hasn’t yet been added to QuickBooks, you’ll see a dialog box on the right side of your window asking whether you want to add the project to QuickBooks. Click Yes to start the export process.
A smaller window will pop up prompting you to click the Export button to add the project to your QuickBooks customer list. If the customer for the project you’re exporting already exists in your QuickBooks file, the project will be added as a Project under that customer in QuickBooks Desktop, and a Sub-Customer in QuickBooks Online.
Once the Export button has been clicked and a sync between BigTime and the QuickBooks file has completed, your BigTime project will appear in QuickBooks. If you receive an error when exporting a project to QuickBooks and the customer already exists in QuickBooks, check the QuickBooks Customer Link at the bottom of the project's Client tab in BigTime to ensure the correct customer is selected.
