Use the Days Sales Outstanding (DSO) Report to calculate DSO on a monthly, quarterly, or annual basis, so you always know how long it takes Customers to pay you and can supplement the way you build your financial forecasts. Use the standard report filters to segment your data and see the DSO for a particular group of Customers.
The DSO Report is part of Maxio Platform's Advanced A/R Management functionality. For more detail, see Understand How A/R Management Works. To add this report to your account, contact Maxio Support to discuss enabling this add-on module.
Go to Reports > Add Report > Finance Reports > Days Sales Outstanding (DSO) to open the report.
