The most helpful feature is that you can create multiple categories for your invoices. This makes it easier to keep up with them in one place. I wish there was an app like this available when we used QuickBooks Online! Also, sometimes the apps don't work as well as they should. For example, if you have many transactions, some times you will get errors or won't be able to add another transaction. It's hard to find a good product out there right now because everything seems outdated. We are using it to help our small business stay organized by tracking payments received from customers.
