When you say contracts, are you referring to like sales forms, invoices, and estimates? If so, you can use the QuickBooks Online mobile app to create and send your sales form and, you can capture signatures from your customers.
If you're referring to an actual contract with details of the work agreement, the feature you're looking for is unavailable in our set of features and offerings. Your ideas are very important to us, our engineering team can consider your suggestion for product updates in the future. In the meantime, you can check for an available third-party application about the electronic signature for contracts.
