Own software foundation — not a client deploymentWarehouse management platform

WMS Core — Warehouse Management & Fulfilment Platform

A custody-first warehouse management platform for multi-seller fulfilment, with an SLA-driven order queue and a seller portal.

This foundation has not yet been deployed at a customer warehouse. It is a configurable software foundation, not a turnkey SaaS product.

Business challenge

The problem it solves

A multi-seller warehouse must prove who owns and who holds every unit, process orders against deadlines and bill sellers accurately, without the ambiguity that spreadsheets create.

Solution

What LATYNEX Digital built

A ledger-based platform where stock, custody, audit and billing derive from the same recorded events, with role-based office tools, a seller portal and device clients.

What it demonstrates

What this shows we can build

  • A ledger-based platform in which stock, custody, audit and billing derive from the same recorded events, with office tools, a seller portal and scanner clients.
  • Controls in the data layer: an append-only stock movement ledger, a hash-chained audit log and row-level security on tenant tables.

How the same capability could serve another business

A business that has to account for stock, orders and several parties could build on the same event-ledger approach for inventory, orders and billing.

How it works

From input to outcome

  1. 01

    Every movement is recorded

    Receiving, putaway, picking, packing, shipping and returns all write to an append-only stock movement ledger.

  2. 02

    Balances come from the ledger

    Stock balances are derived from recorded events; ownership is kept separate from custody, and discrepancies carry responsible-party attribution.

  3. 03

    Orders are ranked by deadline

    The office application ranks orders by SLA and cut-off, with blockers such as missing marking.

  4. 04

    Sellers see their own data

    A seller portal shows stock, open orders, invoices and charges; billing covers tariffs, billable events and invoices.

Technical approach

How it is engineered

A TypeScript monorepo: a Hono API on Node, PostgreSQL with row-level security and monthly partitioned ledgers, Vite and React single-page apps for the office and the seller portal, and an Expo app for scanners. Unit, integration and browser test suites accompany it.

Status and limits

What this page does and does not claim

  • This foundation has not yet been deployed at a customer warehouse.
  • It is a configurable software foundation, not a turnkey SaaS product.
  • Shown on a synthetic demo instance with the receiving-to-shipping flow driven through the real services; there is no public URL.
  • Marketplace order-feed adapters exist in code; their live behaviour has not been validated.
