Why are the projects still available in Zoho Books even after disabling the integration?

If data was synced through the integration and then the integration was disabled, the synced data will be considered as native projects and their time logs within Zoho Books will be retained.

You can either:

• Delete the projects from Zoho Projects while the integration is active. This will ensure that the changes are reflected in Zoho Books.

or

• After disabling the integration, manually delete the projects from Zoho Books post deleting the associated transactions. This will remove the projects from your Zoho Books organization.
