# Combined projects

You can use combined projects to combine projects for the same customer in one overview. This makes managing several projects for the same customer easier because it provides an aggregated summary of key performance indicators. It also provides a function to combine the billable lines of the combined projects in one invoice. When the invoice is posted, the ProjectLedger entries are created in the individual projects.

Besides the **Summary** and **Billable** pages, the following pages can be opened to show the respective lines for the linked projects:

- **Planning**
- **Delivery**
- **ProjectWIP Cockpit**

## Steps - Create a combined project

Combined projects and projects are two separate entities. To combine a number of projects, the projects must first exist for the same customer. Then create and release a combined project header. Next, link the projects to the combined project by selecting them from a list. The relation between a combined project and a project is 1:1.

1. Make sure several projects for the same customer exist in the **Project List**.
2. Open the **Combined Projects List** and select the **New** action to create a new combined project. Make sure to specify the same **Bill-to Customer** as in the projects.
3. Release the combined projects header.
4. Select the **Link Projects** action in the ribbon. This lists the projects for the **Bill-to Customer**.
5. Highlight the projects you want to link (hold down the Shift or Ctrl key to select several projects). When done, click **OK** to link the projects.

> The **Summary** action shows an aggregated ProjectSummary for all combined projects.

## Steps - Create a combined invoice

You can create project invoices from the combined project through the **Get Contract Lines** action. This action lists all contract lines for the **Bill-to Customer**. The filter options in the header allow you to quickly make the required selection.

1. Make sure the selected projects have several contract lines.
2. Select the **Billable** action in the header to open the **Billable** page.
3. The **Billable** page shows all billable lines for the combined project.
4. Highlight the contract lines to invoice and click **OK**.
5. Select the **Create Invoice** or **Create Credit Memo** action from the ribbon to create the document.

When selected and confirmed, the invoice is created.
