Featured builds

Current Finance Systems Lab builds

These are the newest proof assets. They sit at the front because they map directly to the work finance teams recognise: closing, reconciling, cleaning ERP data, preparing VAT evidence, and documenting system requirements.

Shows: close control design, exception tracking, review discipline, and evidence pack thinking.

Stack: Python · Streamlit · pandas · Excel · tests · GitHub Actions

Earlier foundations

Additional proof of work

The earlier projects stay in the lab because they show the data, diagnostics, reporting, and AI workflow foundation behind the newer builds.

Finance ETL Pipeline

Raw ERP CSV extracts become validated close data, curated outputs, BI-ready tables, data-quality exceptions, and dashboard-ready reporting information.

FinSight Lite

Accounting exports are transformed into governed finance marts, anomaly detection, KPI dashboards, and CFO-style commentary.

Finance Operations MCP Server

A structured tool layer showing how finance workflows, ERP data, reconciliations, reporting controls, and AI-assisted analysis can connect safely.

Odoo 19 MCP Server

An Odoo-focused bridge showing how finance systems can interact with AI tooling and external workflows through a controlled server approach.

Finance AI Pack Use Cases

Business-facing use cases for VAT/EFD monitoring, intercompany reconciliation, audit evidence, bank reconciliation, and month-end gating.

Sample Finance Diagnostic

A fictional multi-entity SME diagnostic showing maturity scoring, risk findings, control gaps, and a 30/60/90-day improvement plan.

What the lab proves

Finance judgment first. Automation where it earns its place.

The lab is not here to show random apps. It shows the ability to translate real finance operations into reviewable tools: close controls, reconciliations, ERP checks, tax evidence, reporting packs, and implementation documentation.

Operator experience

Built from real month-end, ERP, audit, VAT, inventory, reconciliation, and multi-entity reporting problems.

Technical delivery

Working tools, structured outputs, documentation, tests, and release discipline.

Business relevance

Each build links back to a finance pain a CFO, controller, finance manager, or ERP owner can recognise.

Start with the finance pain, then automate what is worth automating.

Chez Solutions helps finance teams identify the bottlenecks that matter, then turns them into cleaner workflows, stronger controls, better reports, and practical automation.
