We don't replace your SAP.
We govern it from operations.
Four integration modes (from manual import to full bidirectional), a conflict matrix that decides per field who wins, and a multi-connector framework ready to add new ERPs without touching code.

4 modes · 1 productLATAM standard
Start where your IT is comfortable. Scale when you're confident.
Each mode is a configuration, not a product fork. Migrating from Mode 2 to Mode 3 is changing a policy in /settings/erp, not a project.
MODE 02 · READ-ONLY
ERP read-only
StockTech queries the ERP periodically. The ERP remains absolute master. Zero risk of overwriting data.

The mode is not a permanent decision.
80% of clients start in Mode 2 (read-only) during the pilot, migrate to Mode 3 (hybrid) at go-live and reserve Mode 4 (bidirectional) for later phases once there's confidence in the policy matrix.
Conflict matrix · per_field_matrix
Who wins on each field. No ambiguity.
The classic conflict: the ERP says the VIN was sold, but the floor has it in maintenance. The per-field matrix automatically decides, in each case, which source prevails — versioned in code, not in email.

Architecture
Sync is not a cron. It's a governed pipeline.
Inbound and outbound queues, versioned transformations per connector profile, retry with exponential backoff, dead-letter for manual cases, and full audit per VIN and per event.
