Click on the Setup button (with the toolbar) on the left-hand side,
then on the Properties tab,
and then on the Billing tab.
Choose billing option:

for
outgoing and
incoming (per second, per unit).
Then enter your costing per billing option.
In Topaz 1.6.0.4 and newer you can set a minimum fee for billing.
Make sure you click apply (at the bottom) once you have made the required
changes.
Please note that in [TOPAZ -> ENQUIRIES] it will display the Telkom costing.
You have to draw an invoice by Price in [Billings -> Master Billings] to check the markup.
