Automatic billing can help save time and money. For example, if your accounting software automatically generates invoices and dispatches them to clients, you don’t have to manually create the invoice, saving you time. Additionally, you don’t have to worry about forgetting to send the invoice, which helps to keep working capital flowing.If you are a field services professional, you may want to use an app such as Intuit Field Service Management ES. Compatible with QuickBooks, this app lets you track the tasks and time you spent working for a client. Then, it generates invoices automatically based on your entries.In addition to invoicing clients automatically, you may want to use a bill calendar for your accounts payable. Your bill payment calendar can alert you any time a bill is due, which helps you avoid late fees. Some bill calendars can even pay bills on your behalf.
