Is there a way to set up the estimate so that our terms and conditions attachment will automatically be included without having to attach it each time we send the email?

It's nice to have you here, Lorna. We value your business and are committed to providing the best possible service.

The ability to automatically attach terms and conditions to your estimates and invoice is currently unavailable. 

Alternatively, we can manually attach documents to your invoice using the attachment feature in QuickBooks Online. Here's how to attach files on the Attachments page:

1. Go to the Gear icon and select Attachments.
2. Click the Attachments icon to open the files.
3. Hold the CTRL button on your keyboard and select the items to upload.
4. Once everything is set, release the CTRL button and hit Open.

To attach documents on transactions:

1. Open any income or expense transactions in QBO.
2. At the bottom click the Attachments icon.
3. Do steps 3 and 4 from the instruction above.
4. Make sure to click the Attach to email option.
