Money code gets audited. Ours passes.
Financial software fails in ways that are quiet, expensive, and very hard to explain afterwards. Most of those failures are in code an AI wrote confidently.
What usually breaks.
Money stored as floats
The classic. Everything reconciles in testing and drifts by rupees a month in production. Money belongs in integers or decimals, never in a float.
No idempotency keys
The customer taps pay twice, or the network retries, and they get charged twice. AI-written payment code almost never handles this.
Audit trails that are not
Rows get updated in place with no history. When someone asks what this balance was on the 3rd, there is no honest answer.
What we'd do about it.
Bug Fixing & Code Rescue
We move money into safe types, make every write idempotent, and rebuild reconciliation so the numbers agree and stay agreeing.
Security Hardening
PCI-DSS-aware review, card data kept out of your logs and database, and access controls that survive an auditor reading them.
QA & Testing
Tests for the cases that hurt: partial refunds, currency rounding, failed webhooks, double submits, and reconciliation across a month boundary.
Fair things to ask.
Do you handle card data?
We'd rather you didn't either. Where we can, we move you to a tokenising provider so card numbers never touch your servers.
Is your work PCI-DSS compliant?
We build to it and give you the technical evidence. Certification is between you and your assessor. We won't imply we can grant it.
Our reconciliation drifts by small amounts.
Almost always floating-point money. It belongs in integers or decimals, and fixing it is usually a contained change.
How do you stop double charges?
Idempotency keys on every write that moves money. AI-written payment code almost never has them.
Can you work with our existing payment provider?
Yes. Switching providers is a business decision, not something we'd push you into.
We need a real audit trail.
Append-only history instead of updating rows in place, so "what was this balance on the 3rd" has an answer.
Will you touch our production ledger?
No. We work against a copy, and you run the migration when you're ready.
Can you help with regulatory reporting?
We can build the extracts. What you're required to file is a question for your compliance advisers, not us.
