About
Auditors who still walk the aisles
API Data Management grew from year-end inventory work for manufacturers around Taichung and Shihkang. We stay close to the floor because valuation opinions without bin-level evidence rarely survive the first lender question.
Origin
Our early engagements were stock count observations for exporters who needed a letter for group reporting. Clients then asked us to stay for costing layers, aging reserves, and full inventory valuation audits before statutory close.
We remain a practice that bills by engagement—not by seats or licenses. The work is human observation, document testing, and written findings grounded in Taiwan warehouse reality.
How we work
- Scope sites and cut-off dates before anyone picks up a count tag.
- Prefer sampling plans the warehouse lead can explain in one briefing.
- Separate facts observed from recommendations so management can decide.
- Write memos your external accountant can attach without rewriting.

Values that show up in the memo
Specificity over slogans. If a cage was unlocked or a consignment bin skipped, we name it. Courtesy on the floor—count days already stress warehouse teams. Independence in writing—management receives findings before any softener language.
