L4 (Level 4 traceability)

Corporate EPCIS hub for partner exchange

L4 (Level 4) is the corporate traceability layer where serialized product custody is exchanged with trading partners via EPCIS—receive, ship, verify, and investigate exceptions across your network.

L3 covers plant-floor serialization (commission, aggregate, ship-from-manufacturer). L4 is where wholesalers, 3PLs, and manufacturers operate partner-facing workflows: inbound EPCIS, outbound EPCIS, VRS, and compliance reporting.

TracePharma is an L4 SaaS application—it does not replace ERP financial posting or L3 line systems; it handles DSCSA partner-edge accountability.

→ Per-tenant workspace for EPCIS ingest, outbound generation, and ACK monitoring.
→ Profile-tuned navigation for manufacturers, wholesalers, 3PLs, and dispensers.
→ Direct partner connectivity (AS2, SFTP, HTTPS) without mandatory exchange network middlemen.
