Fintech MVP Compliance Checklist: PCI-DSS, SOC 2, and Beyond

Fintech isn't just about moving money—it's about moving money securely, compliantly, and at scale. This guide covers the compliance foundations that must be baked into your MVP from day one.

The Fintech Compliance Stack

Depending on your product, you'll need some combination of:

• PCI-DSS Level 1: Required if you handle, process, or store credit card data directly
• SOC 2 Type II: Expected by enterprise customers and VCs for any B2B fintech
• SOX Compliance: Required for publicly traded companies or their financial software vendors
• AML/KYC: Anti-Money Laundering and Know Your Customer regulations for payment processors
• State Money Transmitter Licenses: Required in most US states for sending money

MVP-Stage Compliance Strategy

You don't need full SOC 2 certification before launching, but you do need the right foundations:

1. Use Compliant Vendors

Stripe, Plaid, and similar platforms handle the heaviest regulatory lift. Build on their rails and inherit their compliance certifications.

2. Encrypt Everything

TLS 1.3 for transit, AES-256 for rest. No exceptions. This is table stakes for any fintech.

3. Implement Audit Logging

Every financial transaction, every data access, every admin action—logged immutably. You'll thank yourself during your first audit.

4. Data Residency

Know where your data lives. Some jurisdictions require financial data to stay within national borders. Plan for this from the start.

"In fintech, security isn't a feature—it's the table stakes for playing the game."

Architecture Decisions That Simplify Compliance

Tokenization: Never store raw card numbers. Use Stripe's tokenization or similar to keep PCI scope minimal.

Row-Level Security: PostgreSQL RLS policies ensure data isolation at the database layer—a SOC 2 auditor's favorite.

Infrastructure as Code: Terraform/Pulumi makes your infrastructure auditable and reproducible. This simplifies SOC 2 evidence collection.
