Updating or Amending a Contract (Terms & Conditions)

Once a contract has been created in Sonas, it cannot be edited directly. The steps you should take depend on the current status of the contract.

If the contract is still pending (not yet accepted)

You can delete the pending contract and create a new one. To do this:

1. Delete the current pending contract.
2. Create a new contract using your template.
3. Make the necessary changes during the pre-confirmation step, before submitting for approval.
4. Send the updated contract for acceptance.

Alternatively, you can create an addendum (a second contract) so the customer can accept both. This is often the easier and faster option if the changes are minor, such as adding a few line items.

Note: You can only edit the content of a contract during the review step before you confirm and send it. Once a contract is generated and submitted for approval, it can no longer be modified in place. There is no "review mode" — editing is only possible before the contract is finalized and sent.

You can also edit a new contract before sending it. When you apply a template and create a new contract, you can modify the content before the final confirmation pop-up. See this video for a walkthrough.

If the contract has been accepted

You cannot amend or delete an accepted contract. Instead, you have two options:

1. Create an addendum — Add a new contract as an addendum to cover the updated terms. The customer can then accept the addendum alongside the original.
2. Create a new superseding contract — Create a new contract and include wording such as "This contract supersedes any previously accepted agreements." It is recommended to consult your manager or legal team to ensure the superseding language is properly approved.

Tips

• If you anticipate frequent amendments, consider using addendums as the standard workflow for handling changes after the initial contract is accepted.
• When creating a superseding contract, use wording approved by your legal team — for example: "This contract supersedes any previously agreed contract."
