How it works with QuickBooks

WOWinflow is an automated, seamless, secure plug-in for QuickBooks. WOWinflow doesn't change any data or settings in your QuickBooks software, it simply analyzes historic invoice data and the payment patterns & behavior of your customers and then uses machine learning artificial intelligence to provide amazingly accurate data to WOW your cash forecasting and help your business avoid bad debt. You can check your connection works before you subscribe and data refresh within the app to ensure you are always working with real projections and scenarios.


When customers' don't pay their invoices on time, it makes it difficult to accurately budget, plan and forecast cash. WOWinflow plugs-in to QuickBooks to learn your customer payment patterns and then accurately predicts your cash inflow. When customer payment patterns change, this normally indicates a problem. WOWinflow alerts credit control to the change and monitors the customer until they're back on track!

Q. How accurate is WOWinflow?
WOWinflow is extremely accurate. Wow inflow learns how each of your customers pay you (including payment runs, payment cycles, direct debits, historic number of days to pay for adhoc payments etc.) and uses this intelligence to predict and plot when your clients will pay future invoices. These predictions are very reliable and if any of your customers payment patterns change, WOWinflow warns you immediately, as there might be a problem with an invoice or they might be having cashflow problems.
