Purchase Requisition Form?

Purchase order 是你公司的購貨員向供應商買貨時用的.
Purchase requisition form 是你作爲普通員工向公司的購貨員要求購貨, 你公司的購貨員就會要求數間供應商提供報價單 (quotation) 格價. 之後, 購貨員就會向最平的供應商買貨而提出 purchase order.
所以, 過程是:
1. general staff issue purchase requisition form to purchaser
2. purchaser ask for quotations from suppliers
3. purchaser select one (or two of) supplier from the quotations. (Two suppliers may be chosen. Because more suppliers can ensure the stable goods supplying.)
4. purchase order to the lowest price supplier

如果你地有購買部(purchase department)，咁佢地會處理所有部門嘅購貨工作，而你就唔可以自行入貨，account係唔會俾錢。由於係第二個部門，所以你叫人做嘢就要跟規矩，你要先填pr form由部門經理簽署，prchasing會審核pr form，睇下有冇超額，有冇存貨，係自用定resell，供應商係咪核准等等。審批後會出po form到供應商。
當然你係一腳踢就無需咁做，但聯絡，交收，追貨等你都要跟進，有purchasing你就慳少少工夫。
所以pr form係內部文件而po form係外部文件。
