# How do I create recurring Invoices for a Fixed cost project?

When a project is created in Zoho Projects and synced to Zoho Books with the **Fixed Cost** billing method, the option to create **Recurring Invoices** for those project timesheets will not be available. This is because fixed cost projects have a predetermined, fixed fee that is not based on variable factors such as staff hours or task hours.

As a workaround you can associate the project at the time of creation of the recurring profile. To do so:

*   Go to _Sales_ and click **Recurring Invoices**.
*   Click the **\+ New** button in the top right corner of the page.
*   Choose the customer and associate other details.
*   Click the **Bulk Actions** option located on the line item table.
*   Click **Show Additional Information.**
*   You will be able to associate the **Project** from there.

If you have choose the billing method **Based on staff hours** or **Based on task hours** for a project and it has been synced with Zoho Books, you can create a recurring invoice for that project. The timesheets recorded for the project will be automatically added in the next child invoice.
