Invoice Manager is great. It has saved me hours of my time in creating invoices, billing, and collections as well as reminders. Customer service is fantastic, people are friendly, its a small company and theyve been very responsive to me so far. Its really easy to make an invoice, too. You dont have to do much to make one. The app also has a ton of useful features!
