UBL, which stands for Universal Business Language, is a standardised data format and a set of XML-based document schemas designed specifically for Electronic Data Interchange (EDI) and e-commerce transactions. UBL serves as a common language for the structured exchange of business documents such as invoices, purchase orders and shipping notifications between trading partners. It provides a framework that facilitates seamless communication in global supply chains and business-to-business (B2B) transactions through the use of predefined document structures, data elements, and code lists.

User Acceptance Testing (UAT) involves testing the functionality of an electronic data interchange (EDI) system to ensure it meets the requirements of end-users. Thorough testing will ensure a smooth go-live and minimise the number of errors post deployment.
