Costs and stock your operation can trust
Event-driven inventory isn’t a technical slogan. It’s why Loribase can show where stock went, why cost changed, and what really happened before your team makes the next decision.

The Loribase Difference
The real problem isn’t the movement. It’s losing trust in the number
Most operations don’t suffer because stock moves. They suffer because the number everyone depends on can’t explain itself. When quantity changes, the team still doesn’t know what happened, who changed it, and if the cost impact has been reflected.
This is what turns routine into investigation. Planning sees one balance, the warehouse sees another, finance questions the margin, and every discrepancy becomes manual reconstruction between spreadsheets, messages, and memory.
When trust in the balance is weak, all following decisions become weak too: purchasing, pricing, production planning, recall response, and margin analysis. The problem isn’t just traceability. It’s operational confidence.
Model
What event-driven inventory means
In the event-driven model, nothing is ever overwritten. Every action that affects inventory (a purchase arriving, a production consuming raw materials, a reservation for a work order, a transfer between warehouses) is recorded as a discrete, permanent event. The current stock quantity is always derived from the sum of all events, never stored as a mutable value.
Purchase received
A new batch enters inventory. The event records the supplier, quantity, unit cost, and lot number. Stock increases.
Production consumption
Raw materials are consumed by a production run. The event records which batch was used (FIFO), the quantity, and the resulting product.
Reservation
Stock is committed to a work order or shipment. It remains physically present but is marked unavailable for other operations.
Transfer between locations
Stock moves between warehouses. Both the source and destination events are recorded simultaneously, maintaining a complete trail.
Manual adjustment
Physical counts sometimes reveal discrepancies. The adjustment event records the reason, the quantity changed, and who authorized it.
States
Four inventory states, always accurate
Because every event is recorded, Loribase can calculate four accurate states simultaneously, without any approximation or polling:
Physical stock
The precise quantity that physically exists in your warehouse right now. Increases with every purchase or production receipt. Decreases with confirmed consumption or outbound transfer.
Reserved stock
The quantity committed to an in-progress work order, production run, or confirmed shipment. Still physically present, but not available for other uses.
Available stock
Physical stock minus reserved. The only number you should use when planning new production or accepting customer orders.
Incoming stock
Confirmed but not yet received purchase orders. Know what is coming before it arrives so you can plan production without waiting for physical delivery.
Benefits
What you gain with event-driven inventory
Complete audit trail
Every stock movement has a timestamp, a user, a reason, and a link to the originating document (purchase order, production run, or adjustment). Nothing is ever unknown.
Accurate FIFO costing
Because purchase events carry the unit cost and date, Loribase knows exactly which batches were consumed by each production run, calculating real FIFO costs automatically, not estimates.
Lot traceability
You can trace any product batch forward (which productions used it) or backward (which purchase lot it came from). Essential for quality recalls, compliance, and expiry management.
No silent overwrites
Data cannot be silently changed. Any correction requires a new event with a reason. Your historic data is always intact and legally defensible.
Real-time without polling
Because state is derived from events, inventory visibility is always current, with no scheduled sync, no batch update, and no two-hour delay before numbers reflect reality.
