If you are a member of a purchasing organization and you need to be added to or removed from a particular contract, you'll have to contact the Contracts Manager within your organization. Unfortunately, Bonfire Support does not have any control over the contracts that you have access to.
If you are a Contracts Manager or an Organization Administrator, by default you have access to all contracts in your department or your entire organization respectively. If you need assistance with adding or removing other people to or from a contract that you manage, see Contract Details under the People section.
