On invoices and received invoices, users can leverage the "Collective Invoice" function. This feature facilitates the addition of a "Receipt" or "Delivery Note" button within the Products and Services widget, allowing users to seamlessly incorporate delivery notes or receipts. This tool serves as a comprehensive recording mechanism for all deliveries and receipts within your company, consolidating them into a unified document.

The functionality is supported by two modules: "Delivery Notes" and "Receipts," designed for the entry of each individual delivery note or receipt. To add a delivery note or receipt, navigate to one of these modules, click the "Add" button, and input the necessary data for accurate and efficient record-keeping.
