I just came over from jobber, and there my clients where able to approve estimates by simply e-signing, very simple made my clients very happy! does quickbook offer this?

You need an additional app to let clients accept your Estimates and integrate it with your QBO. If you run a field service business, you may keep using Jobber or other similar app and integrate it with your QBO.

I was hoping not to have to do that, I like keeping everything in one platform. 

Hi there, usertxbuildingco.

I understand that you want an option for your customer to approve the estimate or by simply e-signing. In QuickBooks Online, the only way you can let your customer sign an estimate is through the QuickBooks Online mobile app.

You'll want to continue using the Jobber by integrating it into QuickBooks Online. You can also find similar applications on the Apps tab.
