Contract stack

Contract stack: The set of documents that together form and govern a contractual relationship between the parties. The contract stack typically includes the main agreement and any related documents, such as specifications, general terms and conditions, annexes and referenced policies or codes. See Sustainability in your contract stack

In practice, the contract stack is often complemented by parallel contracts that influence how commitments are implemented. See parallel contract stack. Individual transactions based on quotations, purchase orders, order confirmations, or similar exchanges, may further specify or operationalise the agreement in practice. See transactional contract layer.
