Customer Type refers to controlled value describing the nature of the customer, such as borrower, co-borrower, guarantor, supplier, dealer, individual, non-individual, existing customer, or new-to-bank customer. In MSME credit workflows, it supports borrower identification, constitution checks, ownership validation, eligibility assessment and regulatory compliance before money is disbursed. For example, name, constitution, ownership and registration details are matched with official documents before the bank proceeds with underwriting or disbursement. It matters because a clean legal and KYC base prevents duplicate records, wrong-party exposure, documentation defects and downstream audit issues. The common mistake is to accept names or numbers without cross-checking them against current official documents, board records, registrations or policy requirements.
