Now, your Zoho Books organization has been connected with your portal in Zoho Books.


  • When you set up this integration, your organization’s name and email address will be shared with Zoho Projects. 
  • If the General Timesheets are not imported from Zoho Projects, go to Settings > Integrations > Zoho Apps > Zoho Projects > Show Details and enable General Timesheets.

Checking the Status of Your Synced Data

It may take a while for the modules to get synced. You can view the status of your integration by clicking Refresh, which will display a Sync in Progress badge if some modules are still getting synced.

Invoice for Zoho Projects

Invoice for Zoho Projects

If you wish to send the invoice to a customer created in your Zoho Books account, leave the customer field blank and create invoice. You can select the customer when the invoice form shows up for editing.

This will include expenses created in Zoho Projects for the above selected project and customer only.

In the same manner, an invoice created in Zoho Projects will also be reflected in Zoho Books. You can view and edit the invoice in your Zoho Books account.

Expenses recorded in Zoho Projects will also be reflected in your Zoho Books account.

Note: Once a task is completed and invoiced in Zoho Projects / Zoho Books, it cannot be invoiced again in Zoho Books / Zoho Projects.

This integration is very helpful when you run a company where you have multiple projects running and if you need to generate reports on the invoices and expenses.
All the invoices that are created in Zoho Projects will be reflecting in your Zoho Books account too, this way you can generate reports from the Reports module in Zoho Books. Plus, it gives access to dual mode communication from Zoho Books and Zoho Projects in regards with invoices.
