One kernel, three outcomes
The process stays clear. The behavior adapts.
One purchase order moves through the same controlled chain. The module decides what the receipt means—without creating a custom database or a hidden workflow.

Ledger-authoritative inventory control
Current - reserved = availableMove it. Count it. Locate it.
Transfers preserve a balanced movement trail, counts post only real variances, and the location matrix derives its position from stock, reservations, and active storage assignments.

Many operating contexts, one kernel
Everything you are permitted to seeDefine product context once. Carry it into the work.
Each module declares its capabilities and product-field profile. When selected, module context travels through the workflow, while purchase requests, orders, receipts, products, and sales remain unified pages.
Historical snapshots stay unchangedWhen a configured field enters procurement, the saved PR and PO context is not rewritten by later product-field changes.
