This is a great app for managing your time and then invoicing it after setting up projects and clients on the website. The last version of the app allowed you to manage your invoices, see whats been paid and update if its been paid. The new version removed that option. I like Harvest because its a one-stop place to track time and then invoice. Would love of the app allowed for both.
