承包商

My boss gives me a free hand in deciding which outside contractor to use.

老板让我自主决定聘用哪家外部包商。

We got estimates from three different contractors before accepting the lowest.

我们得到三个包商的报价, 了最低的报价。

Contractors winning construction jobs had to kick back 2 per cent of the contract price to the mafia.

赢得建筑工作的包商得抽出合价的百分之二的回扣给黑手党。

Therefore in the construction contract uses the advanced payment, the contractor may exercise unassured pleadings to guard project funds is delayed in payment.

因此，在适用预付款的合，包商可以行使不安抗辩权，以防范工程教拖欠。
