You can import service and expense line items from a budget template. You can also import custom fields from the template and its line items or create a unique project budget from scratch. When you import from budget templates to projects, the template details get copied to the budget of those projects.
In case of 'budget templates' in BQE CORE, you can add all the budget details that your team uses most of the time and add line items for all the common activities and expenses involved. In the future, you can create budget templates using the Create From Existing Template option, choose this template budget to copy from. Check CORE Help Center for details.
