The liabilities bill book is used to display all the maturities recorded in the liabilities column, either through an invoice or manually. After selecting a customer and clicking on one payment, it is possible to remove that payment from the bill book by double-clicking on it.
Once the dialog window is open, select the method of payment and click on "OK".
To enter maturities manually, use the option labeled "Insert maturity".
All paid bills will be entered in the journal.
