It's all there
On a contract you can specify which customer or supplier the contract is signed with, when the contract starts and ends, if the contract is for specific product(s) and if a SLA should be used. You can have multiple products on a contract. You can also see billing information on the contract, as well as any custom fields available. A company also has a contract-tab where the contracts for the company are listed. You get everything you need in one place. No more searching for information. It's all there.
