Cloud-based enterprise resource planning (cloud ERP) systems have existed in the business market for around ten years. Cloud ERP supports enterprises' daily activities by integrating organizational back-end systems in the cloud environment. One of the critical functions that cloud ERP offers is the purchasing application. The purchasing function of cloud ERP enables enterprises to streamline all the online purchasing transactions in real-time automatically. Even cloud ERP is deployed quite often these days, organizations somehow still lack the knowledge of it; to be specific, there are many issues attached to cloud ERP implementation yet to be solved. Hence, this paper compares four leading cloud ERP platforms in Australia and proposes a hybrid cloud ERP framework to process online purchasing transactions. By adopting a case study approach, a purchasing web-based application is designed and presented in this paper. In general, the proposed hybrid cloud ERP framework and the integrated web-based purchasing application allow user companies to process online purchasing transactions with short operation time and increased business efficiency; in the meantime, the proposed framework also reduces security risks attached to the public cloud.
