本研究以台灣一家員工人數約十人的小型製造企業（A公司）為研究對象，採用個案研究法，探討其導入Ecount雲端ERP系統後，在訂單管理與庫存管理兩大核心流程上的管理成效。研究資料來源包括ERP系統導入前後之營運數據、企業內部文件，以及對管理階層與主要使用者進行之半結構式訪談，並以DeLone & McLean（2003）所提出之資訊系統成功模型作為分析架構，從系統品質、資訊品質、服務品質、系統使用、使用者滿意度與淨效益等構面進行綜合評估。研究結果顯示，雲端ERP系統在系統穩定性與資料集中管理方面具有明顯優勢，能有效降低小型企業在資訊維護上的負擔。在訂單管理方面，ERP系統透過標準化價格與折扣邏輯，使訂單金額計算錯誤率明顯降低，並提升資料一致性與可追蹤性；然而，由於訂單來源流程仍仰賴通訊軟體，訂單正確率未出現顯著改善。在庫存管理方面，導入初期因料號命名與基礎資料尚未完整建置，庫存準確率短暫下降，但隨著資料標準化與作業流程逐步穩定，庫存準確率呈現回升趨勢並優於導入前水準。整體而言，本研究發現，小型企業導入雲端ERP系統所帶來的效益具有「漸進式」特徵，並非立即全面改善，而是先在高度結構化與可標準化的管理流程中顯現成效。研究結果亦顯示，ERP導入成效高度依賴管理階層支持、資料標準化程度與使用者學習投入。本文之研究發現可作為小型製造企業評估導入雲端ERP系統之實務參考，並補充現有文獻對微型企業數位轉型實證研究之不足。 關鍵詞：小型企業、雲端ERP、訂單管理、庫存管理、資訊系統成功模型;This study adopts a case study approach to examine a small manufacturing enterprise in Taiwan (Company A) with approximately ten employees， to examine the effects of implementing the Ecount cloud-based ERP system on order management and inventory management. Research data were collected through a comparison of operational data before and after ERP implementation， internal company documents， and semi-structured interviews with management and key system users. The DeLone and McLean (2003) Information Systems Success Model was employed as the analytical framework to evaluate system quality， information quality， service quality， system use， user satisfaction， and net benefits. The results indicate that the cloud-based ERP system demonstrates clear advantages in system stability and centralized data management， effectively reducing the information maintenance burden for small enterprises. In terms of order management， the standardization of pricing and discount rules significantly reduced calculation errors and improved data consistency and traceability. However， order accuracy did not show a substantial improvement， as order intake continued to rely on external communication tools. Regarding inventory management， inventory accuracy initially declined due to incomplete master data and inconsistent item coding during the early implementation stage. As data standardization and operational processes gradually stabilized， inventory accuracy improved and surpassed pre-implementation levels. Overall， this study finds that the benefits of cloud-based ERP adoption in small enterprises exhibit a gradual and incremental pattern rather than immediate comprehensive improvement. ERP effectiveness first emerges in highly structured and standardized processes and expands progressively as organizational capabilities mature. The findings also highlight the critical roles of top management support， data standardization， and user learning in determining ERP success. This study provides practical insights for small manufacturing enterprises considering cloud-based ERP adoption and contributes empirical evidence to the limited literature on digital transformation in small enterprises.
