About Invoice Rex
Be the king of your invoices. Invoice Rex is a powerful invoicing tool that allows you to issue invoices, customize their appearance and a lot more while synchronizing seamlessly between all of your devices (macOS, iOS and iPadOS) securely via iCloud without any content being stored on our or anyone else's servers. Aside from issuing invoices, Invoice Rex allows you to track other business-related documents like bank statements, cash receipts, storage, journey log and much more. Invoice Rex is designed with you and your comfort in mind - it is simple to use, yet powerful. But if you need any help, there's always a user guide available right from within the app. And if that does not answer your questions, there's a support dialog in the app that allows you to contact us with just a few clicks or taps. Customize the template for printing invoices, bills and other documents just the way you like. Invoice Rex has been written using the latest UI technologies Apple offers, allowing for a single implementation of both its core and the UI to be shared across the entire Apple ecosystem. Invoice Rex is free to use for the first 14 days, then a subscription is required to use the app. You can choose to be billed either monthly or annually.
