It’s possible to collect e-signatures using the built-in tools that you’d see in Microsoft Word, but we don’t recommend it. The problem that you’ll encounter has to do more with document management and signing order than with certified signing solutions.
Inside Word, you can create an encrypted signature, but if you have to send that document to more than one person, you’ll end up needing to send it by email to one individual at a time. Once an individual sends it back, you can send the updated document (with the newest signature) to the next person and repeat the process.
As you can imagine, this gets tedious quickly.
But there is a workaround if you like using Word or Docs to write contracts and proposals: Add-ons like PandaDoc for Word and PandaDoc for Google Workspace allow you to create content using your preferred tools and then use specialized e-signing platforms like PandaDoc to acquire your signatures, so you can get the best of both worlds.
