Both of these apps are integrated with Google Drive so you can work seamlessly on the files hosted there.
1- HelloSign
HelloSign allows you to easily sign your Drive documents online.”Choose any file in Google Drive and add your signature (or text, date, checkmark, etc.) It’s that simple. You can sign and send any type of document (PDF, Word, Excel, etc.).” You can also use it to request signatures from others. You simply upload the document you want others to sign then assign the signature field and send off your request. When you integrate HelloSign with your Drive, you will get a special folder in your Drive for your signed documents and signature requests.
2- DocuSign
Similar to HelloSign, DocuSign also enables you to easily sign your documents and PDFs online. You can also use it to fill out forms and collect signature from others. “With just a few clicks, you can sign or send any document for signature right from Google Drive or Gmail. No printing, faxing, scanning, or overnighting required.” Watch the video below to learn more about DocuSign
