Supplier identification

To process an invoice, the supplier number must be identified first in M3. Because invoices do not contain the M3 supplier number, this solution uses this multi-step search process to find a match automatically:

• Exact Match Search (High Priority): The system searches for a unique and exact match using the most reliable data extracted from the invoice, such as VAT registration number and Bank Account Number.
• AI-Based Search (Fuzzy Match): If no exact match exists, the system uses AI to search for the supplier based on less structured data—Supplier Name, Address, Number, and Email Address—to find a single, confident match.

If the process cannot identify a unique supplier, the system automatically sends the invoice to the Review Center for manual selection.

This table outlines the order in which data is searched, along with the corresponding fields and programs in M3.

Sequence	Data	M3 program	M3 field name	Comment

5	Tax ID number for supplier	CRS624	TINO	Exact match is required.
5	Supplier name (Mandatory) Address fields (All addresses) Supplier email Phone number	Data Lake	N/A	Any combination of these fields that matches to a certain percentage, which is configurable at the time of implementation.
