公司sales scheme:

Commission calculation: On sales amount after sales payment received from client
Payment period : end of each quarter

請問如果 sales order係 partial delivered, 已經收咗客部交付部份嘅payment, 離職嘅partial嘅佣金有冇得收呢？

另外如果 sales order係completed delivery, 但payment terms有5% retention未收，會係送完貨之後12個月後先找，未收倒最後final payment 就離職，情況又會係點樣呢？

請指教.
