When you've been granted contact on a job and have discussed the job details with the homeowner, you can send your quote directly through Builderscrack. The benefit of this is that it keeps a record of the job details all in one place which is accessible for both the homeowner and the tradesperson.
Open the job from your Active Jobs list.
You can then fill up to 3 variations of the quote. You'll be shown a preview of the quote (which you can then edit) before it is sent to the homeowner.
When the homeowner receives your quote, they can accept, decline or query the quote.
