When one party consider that all the terms in a request are suitable, they can confirm the request. This will notify the partner that they want to move forward with this request. However, it does not mean that the deal is binding yet.
To make the deal official, the other party needs to accept the deal. This serves as a double confirmation to ensure that both parties agree on the latest terms. Once a request is accepted, the supplier can provide a release reference.
Below you see the Confirm modal and the Accept modal.
