Please add a Document Center and a feature for Signing Contracts similar to Docusign.

Hello @hometownnetworks,

Welcome to the Community. I'm here to help you with your concern about the features you need in QuickBooks Online.

It would be beneficial to have a Document Center or sign contracts directly within QuickBooks. Our engineers might consider bringing this feature over to this platform in the future.

These features would be a great help that users can use without using third-party applications. As we assess this, I suggest you visit our Feedback section to let our product engineers know about this idea.

Here's how:

1. Click the Gear icon in the upper-right corner.
2. Select Feedback below Profile.
3. Share your feedback.
4. Hit Next to submit.

I've also attached a link you can visit to know about the type of transactions you can keep attachments in QuickBooks: Attachments in QuickBooks Online.

Feel free to click the Reply button if you have additional concerns about the features in QBO. I'm always around to lend a hand. Take care.

If you are using QBO Advanced, they offer a built-in integration with Docusign and Pandadoc.

But you will need a 3rd party app to store documents like invoices and bills, and integrate it with your QBO.
