Subprocessors
The complete list of third-party infrastructure and service providers that process platform data.
Security Architecture
Our security invariants: AES-256-GCM encryption, SAQ-D scope isolation, and tamper-proof audit trails.
Contractual commitments backed by code
Unlike platforms that rely solely on policy documents, BillingMart enforces its legal and privacy commitments at the compiler, database rules, and architecture level.
Zero Card Storage
PAN and CVV numbers exist solely as volatile memory variables in the charging function. We store only the card type and last 4 digits under PCI SAQ-D scope isolation.
Server Arithmetic
Totals cannot be tampered with on client devices. Invoices and charges re-derive all sums server-side in integer minor units from verified line items.
Verified Contacts Only
Invoices and payment links resolve only through cryptographically verified customer email or phone contacts, preventing unauthenticated access or misdelivery.
Human-in-the-Loop AI
Autonomous AI agents (via MCP) can read, draft, and propose, but cannot send invoices or move money without explicit authenticated human approval.
