The client recognizes that its timely provision of responses, assistance, collaboration, complete and accurate information and data from its executives, agents and employees, as well as configured IT products (together “cooperation”) are essential to the provision of professional services and that the company is not responsible for a defect in the provision of professional services if such a deficiency is due to the absence of full customer cooperation. Each contract theoretically consumes UW resources. If there is never a payment, then UW receives nothing and UW therefore has a specific interest in minimizing the appearance of contracts that are terminated without payment. And it is reasonable to think that some of these contracts are unfortunate results. Next time you get the customer to pay you 1 $und that will solve the problem. The use of contract proposals is a great way to save time during the contract design process, but it requires special attention during the contract review phase. Spaces must be filled or removed before the final contract is signed. Depending on the circumstances, failure to fill a void in your contract can have costly consequences for your business.
