Achieving 99.9% Stock Accuracy
with SandBox WMS
How a leading distribution company eliminated stock discrepancies between their warehouse and the Accurate accounting system.
The Company
A leading distribution company based in Jakarta, operating multiple warehouse facilities and serving over 2,000 retail customers across Indonesia. They rely on the Accurate accounting system as their financial backbone for managing inventory valuation, COGS calculations, and financial reporting.
The Challenge
Before using the SandBox WMS, the warehouse frequently had discrepancies between physical stock and the Accurate accounting system. These gaps manifested in several painful ways:
Physical stock counts regularly deviated by 15–30% from what Accurate showed, eroding trust in the system.
Monthly reconciliation took 3+ days of manual effort, tying up staff and delaying financial closes.
~8% of orders had fulfillment issues — wrong items, quantities, or delays due to phantom stock.
Inventory write-offs averaged IDR 500M+ per quarter due to untracked shrinkage and misplacements.
The Solution
SandBox WMS was deployed with full integration to the existing Accurate system. Key implementation elements included:
The Results
After implementing SandBox WMS, stock accuracy reached 99.9% consistency with the Accurate accounting system. The transformation was dramatic:
"We used to dread month-end stock counts — the numbers never matched Accurate. Now, with SandBox WMS, our physical stock is always 99.9% consistent with the system. The finance team trusts inventory data for the first time in years. It has fundamentally transformed how we operate."
