In practice it looks like this: Let’s say a photography studio employee is out shopping for props for an upcoming photo shoot, and their card limits them to spending $100. When they get to the register they discover that the actual cost is closer to $110. That employee can shoot a request over to their manager asking for an additional $15, and Dash will send a push notification to that manager. The manager can approve the additional funds right from their phone, or from within Slack (a popular office communication platform).
Holy micromanager.
