I've been looking for approval system for our internal financial control. ApproveIt is very user-friendly especially, if your company is using Slack and Xero. I was able to add all of the team members in Slack and they can received the request and process approval via Slack without login in another portal. Integration with Xero is getting better. Also, the ApproveIt team is very responsive to resolve errors and issues by accepting our suggestions and feedbacks. They are quite flexible. I can see more various possibilities to use ApproveIt in HR and others departments.
