近年來，隨著平板電腦市場的迅速成長，以及軟硬體功能不斷地創新，其成長得速度甚至已超越了筆記型電腦與個人電腦，平板電腦具備了輕薄易於攜帶的特性，使得平板電腦的應用也愈趨多樣化，人們不再只是用平板電腦上網娛樂，也開始應用於工作上、學業上等。
雖然目前於AppStore上的軟體相當多，但應用於企業的完整系統並不多，而目前企業應用最多的功能，還是以呈現資料與查詢為主，畢竟在個人電腦與平板裝置上的操作有極大的差異。本研究是以平板電腦iPad為主，使用Apple推出的開發工具Xcode來建置一套進銷存管理系統，其功能具備了產品、客戶、供應商、進退貨、銷退貨、應收、應付的管理及各式的統計報表，可使小型的公司或店家利用此套系統來管理每天的進銷貨、應收應付狀況，並能讓使用者可以得到很好的平板使用體驗，讓iPad的應用面更廣。

In recent years, the tablet computer market has developed rapidly and surpassed that of both notebook and desktop computers due to continued innovation in hardware and software functions. Tablet computers are light and easy to carry and have increasingly diverse uses. People no longer use tablet computers just for entertainment and browsing the web, but have also started to use them for work and academics.
Although there are currently many Apps in the App Store, not many comprehensive systems are applied to corporations. The functions most commonly utilized by corporations are for presenting data and searches; after all, operations on desktop computers and tablet devices are very different.
This study focuses on the iPad, using Apple’s development tool Xcode to create a purchasing, sales, and inventory management system. The functions of the system include management of products, clients, suppliers, orders and returns, sales and returns, payables and receivables, as well as creating various types of statistical charts. Small companies or stores can use this system to manage day to day purchases and sales, as well as receivables and payables: ensuring that users have better experiences using tablets and that the iPad in particular can be more practically applied.
