Audit-Grade Expense Tracking — Forensics-Ready, Day One.
Every action recorded immutably. Every permission server-enforced. Every transaction traceable to actor and timestamp. Built by a cybersecurity company — not as a feature, as a baseline.
Built for: Finance heads, compliance officers, and CFOs who need expense data that holds up under audit, due-diligence, or legal scrutiny.
The status quo is broken
What you're probably dealing with today.
Spreadsheets are editable — no proof of who changed what when
Email approval chains are forgeable and unsearchable
Auditors demand provenance you can't produce
One bad actor with admin access can rewrite history
How PayMint solves it
The features that directly fix this.
Append-only audit log
Every create, edit, approve, reject, pay action is recorded with actor UID and server timestamp. No one — including super admins — can erase their own history. Server rules block tampering.
Server-enforced permissions
All access control lives in Firestore Security Rules — not the client. A compromised browser cannot read another branch's data even if its JavaScript is rewritten.
Atomic, idempotent operations
Voucher numbers, counters, payment status — all issued inside transactions. Concurrent operations never collide; replay attacks never produce duplicates.
Soft-delete with full recovery
Records are tombstoned, not destroyed. Recover from accidental deletes, bad-actor edits, or ransomware-grade incidents with a single click and full audit trail intact.
“Auditors completed our review in half the time because every transaction had clean provenance.”
Frequently asked
Questions buyers actually ask.
How does PayMint prevent insider tampering?
Three layers: (1) Firestore Security Rules deny edits to historical audit entries even with admin credentials. (2) Voucher numbers are immutable post-creation. (3) Every privileged action is itself logged in the audit trail. The system records the audit of the audit.
Do you support data residency in India?
Yes. We can deploy on Firebase regions in Asia (Mumbai). Customer data never leaves the chosen region. We can also deploy on private GCP / AWS environments for enterprise customers.
Is PayMint SOC 2 / ISO 27001 ready?
Built to those standards. We can provide compliance documentation packages on request. Continuous security review by AEGIBIT's cybersecurity team.
How long is audit data retained?
Indefinitely by default. Audit logs are append-only and never expire. Customer-configurable retention policies available for jurisdictions with specific requirements.
Can our external auditor get read-only access?
Yes. We provision a 'auditor' role with read-only access scoped to a date range you specify. They can query, export, and verify without any write capability.
