With Joist, you can copy or duplicate an existing estimate or invoice to create a brand new document with the same content.
Similar to a 'Save As' button, you can copy or duplicate an existing document and then make changes to the new document (i.e. add a different client, edit the items, etc).
1. Open the Estimate you want to duplicate
2. Tap More in the top right corner, and then Duplicate
This will create a copy of your estimate!
