A new foundation for ERP design

Trade Control is a unique business system, re-writing the book on how ERP applications are designed and implemented. Trade Control introduces a unified model that replaces centuries‑old DEBC ledgers and ERP orders by treating both money and goods as flows with polarity.

This site is the home of:

• Theory and Strategy: production and financial systems, new horizons
• Guides and Documentation: user, technical, and “getting around”
• Proofs and Examples: reconciles the maths with statutory requirements

Current Status — December 2025

Trade Control is in active re-development as a free software AI‑native ERP system.
The prototype worked but was not commercially delivered; we have archived those repos as prototypes for AI development. What remains is the Seed Code and the Production Theory, now aligned with a deployment framework.

Progress so far:

• Schema design brought into explicit alignment with Production Theory
• Framework for deployment established
• Deprecated prototype‑targeted instructions from the website
• ASP.NET app undergoing AI‑ification — the Category Tree is the first sapling in the levelled garden of creation

Although Trade Control is not yet ready for deployment, the first milestones are clear:

• Phase 1 Accounts Mode release, replacing DEBC ledgers with polarity‑based flows of money.
• Phase 2 MIS Mode release, replacing ERP Orders with polarity-based flows of goods and service.

By Phase 1, this homepage will feature a Deploy button to activate Accounts Mode.

Next Steps

• Numerical proofs (capital, VAT, transaction‑grained control)
• Operational proofs (node polarity, supply chain scheduling)
• Technical artefacts (spreadsheets, guides, Codex entries)
• User Guides (cashbook, accounts, HMRC Digital filing)

Stay tuned as we move toward the first milestone release.
