Revisions are a way for you to track changes that the client requests to your original proposal, while it is still in the bidding process. For example, you may propose one solution to a client, and they review it, then want to upgrade some of the equipment or require additional solutions. You can create a revision, which is a copy of the project at that state in time." You then make the requested changes to the project and present it to your client.

Revisions can also be compared against each other to view the changes that took place between them.

Revisions are managed in the Project Explorer interface via the Revisions tab at the bottom of the interface.

Every project starts at Revision 0 and then counts up from there as more revisions are created.
