InView allows you to add your Xero invoices and bills to your desktop and mobile calendars. It's aimed at companies to help them easily manage their businesses without breaking from their usual workflow.

Whether you use a calendar from Apple, Google or Microsoft, you will have a visual insight into which invoices are owed or bills you need to pay — all from your computer or mobile devices. No apps are required to be downloaded.

Slack users can opt for a daily digest of bills and invoices straight to your workspace.
