In addition to the terms of a sale, a sales contract can be used as evidence of a transaction. For sales contracts with a payment plan, i.e. the buyer pays in installments, the seller must provide a receipt to the buyer after each payment. Providing regular receipts can be very helpful when the buyer makes cash payments. While pricing usually means that sellers agree on the price, it may also include agreements between buyers to determine the price at which they will buy products. In 2008 in the United States, LG Display Co., Chunghwa Tubes and Sharp Corp., agreed to plead guilty and pay $585 million in fines for conspiracy to fix the prices of lcd boards. If you establish a sales contract for a service, you must also draw up the required payment plan. However, in these contracts, the term “payment” refers to the fact that the buyer will pay for the goods or services he receives. Your contract may require the form of payment you want, including: Contract price, defined as the price of a contract paid to a contractor at the time of conclusion is used if a contract exists. Since a contract is an agreement for the completion of a type and quantity of work, the contract price is fully paid to a contractor when he has completed the agreed work. In general, the contract price includes a down payment, may include some additional payments and ends with a final amount paid at the conclusion of the contract.
British competition law prohibits almost any attempt to fix prices.  If all suppliers choose to increase prices at the same time, this goes beyond the framework of input cost changes. (6) When an audit reveals incorrect information about subcontractors` costs or prices, the information necessary to reduce the prices of premium contracts and subcontractors can only be available within the post office. To the extent necessary to ensure a first-rate price reduction of the contract, the contractor should make this information available to the supplier or an appropriate subcontractor upon request. If the publication of the information compromises the security of the postal service or reveals trade secrets or confidential business information, the contract agent can only disclose it under conditions that protect them from inappropriate disclosure. The information provided should be limited to information that will serve as the basis for the reduction of the price of the main contract. In order to allow the supplier to take corrective action, the supplier should inform the supplier in advance before deciding to reduce the price of the main contract. The Net Book Agreement was a public agreement between British booksellers from 1900 to 1991 to sell new books only at the recommended selling price, in order to protect the incomes of small bookstores. The agreement failed in 1991, when Dillon`s large book chain began deconstructing books, followed by Waterstone`s rival.   If the price of a new supplier is less than the normal offer price of the business, it may be an agreement between existing firms.
