The Excel Invoicing System combines product inventory management, customer relationship management and sales invoicing with performance reporting in the Excel environment. The Excel invoice template serves to create customer invoices with options to save and load customer and product details into the system for later use. Product and customer lists with associated data can be imported and exported between the invoicing system and back end systems as a solution to synchronize sales orders with centralized systems. Inventory levels are updated automatically as sales are made and customers invoiced. The sales reporting analyzes profitability measures for both products or services and customers with breakdown results between any two specified dates. The Excel invoicing functions on both Windows and Mac versions of Excel suitable as a portable sales invoicing solution for multiple remote representatives within the same organization.
