When a contract owner opens the contract that is in the In Negotiation - Review Received state, a review summary dialogue box will appear. Refer to the sample screenshot below.
When the contract owner proceeds to the contract details page, they can view the changes and comments made by the negotiators.
There may be instances where a contract owner intends to resend the contract for negotiation without making any changes in the document. In such cases, they can reply to the negotiator comments, or add new ones and resend the contract for negotiation directly.
To resend for negotiation:

Note:
A contract owner can accept or reject the changes made by the negotiators only when the contract document is in the Draft state. However, one can view the changes made by the negotiators when the contract is in the In Negotiation Review Received state.
To accept or reject the changes using Zoho Writer:

Note: Only the contract owner can accept or reject the changes made by the negotiators.

Tip:
The contract owner can also accept or reject the changes from the Changes panel when the document editor is in Review mode.
Note: Comments added to the contract document using MS Word are not displayed in the Zoho Contracts interface. You can use the Edit in MS Word option to view or manage the comments.
Note: If you have any changes made by the negotiators that you have not accepted, they will be removed upon marking the contract as negotiated. Similarly, unresolved comments will be marked as resolved.
