But if you're shortening the delivery period and not increasing the pay offer, something has to give somewhere.

但是，即使你减少交期却不增加价格，你总得在别的方面给点吧。

I realise the budget for the project has already been drawn up, but there is some possibility for leeway on the delivery period.

我明白这个工程的预算已经做了，但是在交期上可能还有些回旋的余地。
