Most client-related operations can be carried out from the Customer's Operations Center. This form displays the current balance of the selected client. How much they have been invoiced for, how much they have paid and any write offs or credit and debit notes.
If you wish to change the customer's details you can do so by clicking the Change button. Or you can view those details.
Any operation selected from this form activates the relevant form with the existing customer already selected.
Invoices may be created to allow the maintenance of invoices as a job is carried out. Invoices can be created at any time, there is no automated billing timetable.
You can change the amount of an invoice until a payment has been made. After that descriptions can be changed. Once a payment has been made change the amount due by entering write offs, debits and credits.
