Hello, Klindquist.

As mentioned on the previous answers, adding a second page for contract is unavailable. For now, I’d recommend following the suggestions above which is through attachments.

You can also use the Memo field to enter the terms you’d like to say (By accepting the estimate you also accept our Terms & Conditions). 

Another way is to add this on the footer. Here’s how:

1. Click the gear icon at the top. 
2. Select Custom Form Styles. 
3. Click Edit on the form style involved. 
4. Go to Content and select the footer part. 
5. Enter the details on the Add footer text. 
6. Select Done.  

I’ve also submitted a request for this and hopping they’ll consider adding it to our future updates. 

Post a question again if you have other concerns.
