Billdu has created a feature where your clients can accept your quotes or estimates.
When you send an estimate to your client, an "Accept Estimate" or "Accept Quote" button appears. When your client clicks on it, the estimate gets accepted.
The estimate's status in the app changes to Accepted
We send you an email and notice you about it
You will also get a push notification
You can turn it to an invoice - take a look here
Remarks:
Only the recipient can mark it as accepted
It is only possible to change the status in the application
It's not possible to "unmark" it back
