The Line Item Sub Data Model is designed to standardise and simplify the representation of individual line items across various accounting documents and platforms.

As a sub data model, it is always referenced by another data model, such as bills or invoices. This structure allows for efficient organisation and retrieval of address information, ensuring a streamlined approach to handling address-related data.

Unified line item representation: The model standardises data across different accounting platforms, simplifying access and management of line item information.
Multiple data model support: The Line Item data model can be linked from a range of data models, such as bills, invoices, credit notes, expenses, purchase orders, and sales orders, providing a unified structure for diverse use cases.
Calculated values: Pre-tax subtotals, tax amounts, and total amounts are included in the data model, streamlining financial calculations and document summaries.
