Build a Zero-Loss Financial Ledger or Commission Engine
Commission errors cost clients real money. Bank reconciliations that do not balance are a compliance risk. I build transaction pipelines protected by proved two-writer SQL concurrency — your numbers balance at peak load, every time. Same-store audit means every mutation has a permanent, verifiable record in the same transaction. On one multi-store ledger: £127.4M audited with zero reconciliation discrepancies.

What you get
Who it is for
Businesses handling financial or commission transactions across multiple stores, tenants, or departments. Suitable for retail groups, financial services, insurance platforms, and any organisation where a ledger discrepancy is unacceptable.
How it works
Every financial write — debit, credit, commission allocation, settlement — executes inside a single SQL transaction. The same transaction writes the business mutation and its audit record. No out-of-band logging, no eventual consistency, no dual-write risk. Concurrency control uses row-version predicates: two writers cannot modify the same ledger row simultaneously. The second writer receives a version-conflict error and retries against fresh data.
