Securing billing in a breach-heavy world
Protecting invoicing data is more than passwords: segregation of duties, vendor inventory, and provable trails for payment and tax changes keep you out of the worst headlines.
Treat vendor bank detail changes like wire-fraud choke points. Require two eyes, preferably out-of-band confirmation, before any payout destination switches—your AR team should assume every urgent email is suspect.
Authenticate finance power users properly (SSO plus MFA where available) and treat integration keys like production secrets: scoped, rotated, and never pasted into shared docs.
Maintain a register of subprocessors touching payment-related data for privacy and DPIA work, encrypt in transit everywhere, and log who changed tax codes, numbering series, or document templates—the same granularity you’d want in an external audit.
