financial-controls

Fifty runnable Python systems for finance & tax — month-end close, cash & debt reconciliation, partnership 1065/§704(c), tax workpaper build & carry-down, cross-border surplus & ACB, read-only validation, Triangulate multi-agent AI review, and a knowledge brain. Human-gated, fictional data, 495,064 tests, CI-backed, MIT.

Governance-first AI agent platform for SOX-regulated crypto finance. Deterministic policy spine, MCP read surface, audit trail.

Check financial AI outputs with an open protocol, 40 control requirements and 24 synthetic conformance cases. Local demo, no API key.

Groundwork for clustering financial controls by function: consolidates control libraries into one schema and strips firm fingerprints. Prototype; clustering not built.

Enterprise case study of a payment-risk early-warning and deposit-control system built with SQL Server, Power BI, and a custom internal application.

Automated AR month-end close engine: subledger-to-GL reconciliation, bad-debt reserve, SOX-style controls, and an independent reviewer that catches preparer errors. Python.

Open-source Go reference implementation for financial reconciliation, post-trade controls, double-entry ledger, corrections, reprocessing and operational reporting.

Automated AP close: 3-way match, duplicate-payment detection, GRNI accrual, GL tie, vendor recon, intercompany stress test. Python, 35 tests in CI.

Financial controls evolving from ACL and Oracle SQL to Python, Jupyter and Pandas, with synthetic reproducible examples

ASSAY — a bounded AI finance controller that reconciles evidence, abstains under ambiguity, and verifies ledger outcomes.

Runs deterministic month-end close checks on Xero trial-balance exports and produces exception packs for human sign-off.
