How to prevent stock discrepancies before they turn into operational losses
A discrepancy almost never starts during the physical count. It starts when the process allows silent edits, unrecorded movements, and decisions based on fragile stock numbers. This guide shows how to remove the cause before the loss appears.

Root Causes
A discrepancy is an effect. The real problem is the process that lets the error happen
When stock does not match, operations usually respond with another count. But the loss already happened: the wrong purchase, blocked production, delayed shipment, or distorted margin. The root causes below show why the problem starts long before the audit.
Direct quantity edits
When users can directly edit the stock quantity field, there is no record of what changed or why. An authorized edit and an accidental overwrite look identical. The system "quantity" becomes a number that anyone can change at any time, not a fact derived from reality.
Concurrent updates without conflict detection
Spreadsheet-based inventory systems have no mechanism for concurrent access. Two users updating the same cell simultaneously will have one update silently overwrite the other. Quantities diverge from reality without any error or warning.
Unrecorded movements
Stock that moves physically but is never recorded in the system creates systematic discrepancies. A production team that "borrows" material and plans to log it later, a shipment that goes out before the system is updated, a return that is put back on the shelf without a system entry.
Averages masking lot-level reality
Systems that use average cost accounting aggregate individual purchase lots into a single blended cost. This makes it impossible to trace whether a specific unit came from a specific purchase and makes discrepancy investigation exponentially harder.
No audit trail for investigation
When a discrepancy is found, the investigation requires understanding what happened. Without a permanent event log, the investigation is a dead end: you know the quantity is wrong, but you have no path to understanding why.
Solution
How event-driven inventory eliminates these root causes
Replace quantity fields with event recording
Stock quantities in Loribase are never directly editable. Every quantity in the system is the calculated sum of all events: receipts, consumptions, transfers, adjustments. There is no "field" to accidentally change. The quantity is always derived from what actually happened.
Make every movement an explicit event
Every stock movement requires an explicit action: record a purchase receipt, create a production batch, initiate a transfer. Movements cannot happen implicitly. If material moved but was not recorded, the system quantity will diverge, and that divergence is immediately visible.
Attribute every event to a user and timestamp
Every event in Loribase carries the identity of the user who recorded it and the exact time it was recorded. Not timestamps that can be edited after the fact, but server-side timestamps set at the moment of recording. Accountability is structural, not optional.
Track lots individually, not as averages
Each purchase receipt creates a separate lot with its own purchase price. Consumption events record which lot was used. This lot-level tracking makes discrepancy investigation possible: you can trace any specific quantity to its source.
Make the audit trail permanent and immutable
Events in Loribase cannot be deleted or backdated. If an error was made, a corrective event is recorded; the original event remains. The complete history is always available for investigation, audit, or reconciliation.
Reconciliation
Proactive vs. reactive stock reconciliation
Even with an event-driven system, physical counts remain important, but their purpose changes. Instead of discovering discrepancies, physical counts become a validation that the event log is complete. When a discrepancy is found, the event log makes investigation straightforward.
Cycle counting
Count a subset of items regularly instead of counting everything once per year. Smaller counts are faster, catch discrepancies sooner, and disrupt operations less. With Loribase, cycle counting results are reconciled against the event log, not just the current quantity.
Triggered audits
When a production batch closes with unexpected material consumption, or when a purchase receipt quantity does not match the order, Loribase flags the discrepancy. Audits are triggered by the system, not by a scheduled calendar.
