The UBS Accounting System does not generate late payment charges (penalties).
You can print the open-item statement to the customer as a reminder to pay their outstanding bills.
The Debtors - Overdue report can be used internally for your finance/accounts to assess.
It can be provisioned as bad debts or for doubtful accounts.
If you need to generate late payment fees, this must be done by billing invoices or debit notes for penalties as a late charge.
Open the UBS Billing System.
Go to Customer & Sales, Select Sales Adjustments, Debit Note, and Create Debit Note.
Complete the bill details, print, and send it to the customer.
You can perform posting to accounts after completing the debit note as follows: Posting to Accounts.
