Improved the quoting system

When you do a quote for a client, what can happen is, that by the time they come back much needs to be changed. Now you can select the make invoice button which returns you to the customer select page, and you can edit it but what we have done is now given you the ability to edit a quote by pressing the edit button in the history view tab which is much faster and easier to use.

Check it out on the new update.
