Earlier this year, Google announced it would allow add-ons for Gmail, and the time has finally come. Launching today, add-ons will allow third-party developers to integrate their services with Gmail directly. The first partners include Asana, Trello, DialPad, Intuit QuickBooks, and Wrike.

The addition will help enterprise users save a bit of time by not requiring them switch apps constantly. A DocuSign add-on is coming soon, which should be pretty helpful. Right now, Google has only added business-facing add-ons, and it’s unclear when more consumer-facing companies will be able to take advantage of the new Gmail capabilities.

Gmail add-ons are currently supported on the web and on Android, but Google hasn’t said when iOS support will arrive.
