Designing Liquidity Controls and Treasury Dual Authorization Protocols
Dual authorization protocols enforce non-negotiable two-person payment approvals directly on bank clearing rails to secure corporate liquidity.
Vendor Master File Protection
Meaning
Administrative security measures preventing unauthorized changes to supplier payment data. Strong vendor master file protection ensures that the bank accounts used for payments are legitimate and verified. It involves strict controls over who can edit the database containing supplier information.
Database Integrity
Maintaining an accurate list of suppliers is a primary defense against invoice fraud. Every change to a vendor bank account requires a phone call to a known contact at the supplier firm. This manual step confirms that the request to change payment details came from the vendor and not a hacker.
Change Control
Software settings can restrict editing rights to a small group of employees who do not have payment authority. When a change is made, a second person must review the supporting documentation and approve the update. This segregation of duties prevents a single employee from creating a fake vendor and sending money to themselves.
It also ensures that the data in the system matches the physical contracts signed by the procurement team.
Fraud Prevention
The cost of a single fraudulent payment often exceeds the annual budget for a treasury department. Protecting the master file is cheaper than trying to recover money once it has left the country. A clean database allows for faster processing because the treasury team trusts the information they are using.
