The difference

Lot, batch and serial traceability that lives in the same ledger as the stock and the sale — FEFO by real expiry, serials tracked unit by unit, under the house that runs your distribution.

Picked by expiry, not by shelf.

Live · lot & batch

Every receipt lands as a lot or batch with a real expiry, and picking is FEFO — first-expired, first-out — so the stock that must move first is the stock the picker is sent to. An expired lot is held, not shipped.

Live · serial tracking

Serialised items are tracked unit by unit — received, stored, shipped, returned — so a single serial's whole life is on the record, and a warranty or a recall resolves to the exact units, not a guess at the batch.

Signature · A recall is a query

A single serialised unit — SN-000482, from LOT-A21 — carries its whole genealogy: traced back to the supplier and the goods receipt it landed on, and forward through issue, shipping and the customer it went to. Lot, batch and serial traceability run in production across the warehouse, so a recall is a query — this lot, these serials, these customers — not a panic.

RECEIPT · ONE HOUSE, ONE LEDGERThe same house that posts 1.66M+ distribution invoices in production runs these operations — one ledger discipline, one approval engine, one team across pay, people and distribution. — derived: c-004 (SAMWEST sql-count) + c-011 (REEDS billing ledger), verified 2026-07 · reconciliation

The lots and serials live in the same ledger the house posts 1.66M+ distribution invoices on, in production — so what shipped, to whom, from which lot, is one query, not a reconstruction across systems.

Lot/batch, FEFO and serial tracking are in production. On Leysco Akili, an immutable INSERT-only ledger makes every movement permanently traceable, in early access. We chip each as it is.

Built for operations that…
  • pick first-expired-first-out by real expiry, not by shelf position
  • hold an expired lot before it ships, automatically
  • resolve a warranty or recall to the exact serials
  • explore an immutable, replayable stock ledger on Leysco Akili early access
The old way → this way

A recall that means calling every customer who might have it → one query — this lot, these serials, these customers
