Fintech
When your transaction data is wrong, everything downstream is wrong.
Fintech teams build products on top of financial data — payments, lending, insurance, trading. The tolerance for error is lower than most industries, but the data pipelines are just as fragile. The BayesIQ Audit Kit scores your transaction pipelines, validates revenue metrics against raw data, and surfaces the schema drift, null spikes, and duplication issues that make financial reporting quietly, confidently wrong.
Why financial data pipelines fail
Fintech data pipelines break in ways that are hard to detect and expensive to discover late. These are the failure patterns the Audit Kit catches.
Revenue metrics that don't match finance
Your product analytics show one revenue number. Finance shows another. The Audit Kit's metric validation recomputes KPIs from raw transaction data — so you can see exactly where currency conversion logic, refund handling, or phantom events introduce the gap.
Payment event telemetry with gaps
Transaction events fire from multiple clients and payment processors. Required fields like currency, payment_method, or transaction_id are null more often than anyone realizes — 5%, 12%, sometimes 20% of rows. The Audit Kit's schema profiling catches null spikes before they reach downstream aggregations.
Compliance reporting on unaudited pipelines
Regulatory figures — SAR filing counts, transaction monitoring volumes, KYC completion rates — are built from the same pipelines as product dashboards. The Audit Kit produces a scored audit (0–100) with severity-ranked findings, so you know exactly which pipeline issues affect compliance numbers.
A/B tests on corrupted baselines
Duplicate checkout events, identity stitching gaps across web and mobile, and inconsistent funnel definitions mean experiment results are measured on baselines that don't represent reality. The Audit Kit's quality checks catch near-duplicates and event inflation before they corrupt your experiments.
Risk scoring pipelines with unvalidated inputs
Credit, fraud, and underwriting models consume features derived from transactional data. If the pipeline feeding those features has null-rate drift or schema changes, model performance degrades silently. The Audit Kit runs 12+ automated checks that flag data quality issues before they reach your models.
What the Audit Kit delivers for fintech
The Audit Kit is a structured product, not an open-ended engagement. Every fintech team gets the same four deliverables — tuned for payment event schemas, multi-currency pipelines, and compliance reporting requirements.
Scored audit of transaction data pipelines
Every pipeline gets a 0–100 quality score based on schema completeness, null rates, duplication, and freshness. Findings are severity-ranked so your team fixes P0 issues first — not the ones that happen to be loudest.
dbt project with staging models
Auto-generated dbt models handle the fintech-specific transformations most teams hand-roll: deduplication of retry events, currency normalization across payment processors, and settlement timing alignment between authorization and capture.
Streamlit dashboard for revenue metric exploration
An interactive dashboard your team can use immediately — explore revenue, refund rates, and transaction volumes with filters for currency, payment method, and time period. Built on the validated staging models, not raw event data.
Metric validation: reported vs. actual KPIs
Side-by-side comparison of the KPIs your dashboards currently report against values recomputed from raw data. Surfaces the exact transformation step where numbers diverge — whether it's a JOIN fanout, a timezone mismatch, or a filter that silently drops records.

Reliability score improvement
A mid-market payments processor found a $340K annual revenue discrepancy and 1,200 silently dropped transaction records. The Audit Kit identified the root causes, and the delivered dbt project with 56 schema tests now catches regressions automatically.

Transaction-aware audit framework
The Audit Kit understands payment event schemas, multi-currency pipelines, and the specific ways financial data drifts. Checks account for idempotency, settlement timing, and the gap between authorization and capture.
Read-only, no PII or PAN required
Schema profiling and null-rate analysis don't require access to cardholder data or PII. The Audit Kit evaluates the structure and completeness of events, not the content. We work behind your VPN or with anonymized and tokenized exports.
Fast turnaround — P0 issues in 48 hours
Severity-ranked findings are delivered within 1–2 weeks. P0 issues — metrics that are materially wrong right now — are typically surfaced within 48 hours so you can act before the next reporting cycle or board presentation.
