Equipment trading mixes supply from owners, demand from traders and end buyers, partial allocations and many conversations. Spreadsheets and inboxes could not show what was available, who wanted it and what had been promised.
Solution
What LATYNEX Digital built
A dedicated workspace that models lots, demand, matches, allocations and deals explicitly, with a database-level oversell guard, confidentiality rules between internal and buyer-facing views, and communications linked to companies.
What it demonstrates
What this shows we can build
Supply, demand, matching and deal stages in one private workspace, with company contacts and communications linked to each record.
Business rules enforced by the system: an allocation cannot exceed what a lot holds (a database-enforced limit), and counterparty views are covered by confidentiality tests.
How the same capability could serve another business
Any business that matches supply with demand, such as a distributor, broker or reseller, could use the same lot, demand, matching and deal-stage model as a private workspace.

How it works
From input to outcome
01
Record supply and demand
Supply is recorded as lots with stage, origin, timing and mandate; demand is recorded by buyer type and use case.
02
Match
The system scores matches and presents trader and end-buyer candidates.
03
Allocate safely
An operator allocates part of a lot to a buyer with an internal economics preview; a database-enforced guard prevents allocating more than the lot holds.
04
Carry the deal
Deals carry compliance, payment, release and transport states, and mail threads link to companies only by exact e-mail address.
Technical approach
How it is engineered
A module of an internal operations application: Next.js 16, React 19 and TypeScript on PostgreSQL, extended by migrations that add lots, demand, matches, deals, company capabilities and network tables, with unit, integration and confidentiality tests.
