An experienced Excel specialist is required to develop customised budgeting templates for an upcoming project. The ideal candidate will possess expert-level proficiency in all of Excel's functionalities, specifically emphasising utilising pivot tables and formulas to extract meaningful insights from source data. The templates need to be efficiently designed for ongoing financial tracking and reporting purposes. They must accommodate flexible views of itemised expenses across multiple categories, projects and periods. The ability to communicate complex financial relationships in an intuitive Excel format is critical as the templates are aimed at non-technical users.
