If you want your manual invoices to not show the service rates and hours, you can do that by customizing the Manual Invoice template. To do so, follow these steps:
- Open the Global Settings > Invoice Templates screen.
- In the list view of templates, under Show, select Manual Invoice and then click Detail for the template you want to customize, say Manual Invoice. Check Core Help Center for details on customizing invoice templates.
- In the detail view under Layout > Time tab, uncheck Rate and Hours for the Show field.
- Save the changes. Core prompts you to save it as a new template.
- Now apply the new template to your invoices to see the changes. Check Core Help Center for details on that.
