Payment history – Sales
Payment history is a key performance index (statistical value) which describes the customer’s ability to pay invoices on time. If the payment history value is 0 (zero) it indicates that the customer (on average) pays the invoices exactly on time. A payment history value of 5 indicates that the customer (on average) pays the invoices 5 days too late, that is, 5 days past the due date. A payment history value of -5 indicates that the customer (on average) pays the invoices 5 days before the due date. Statistics regarding payment history is only based on fully paid invoices. Credit invoices are excluded from the statistics.
List types
Per customer
This list shows the total payment history per customer and it is possible to use the drilldown function. It is possible to update information in this list. You can update the payment history for separate invoices. That is, you can overwrite the calculated payment history with a value you enter as payment history. This can be useful if, for example, there is a late payment that you do not want to affect the payment history negatively, then you can enter a 0 as payment history for that specific invoice.
Per period
This list shows the total payment history per month/quarter/year and it is possible to use the drilldown function per customer and payment.
Per number of employees
This list displays the total payment history by company size (number of employees).
