I may not have made too much sense in the subject line but essentially I need to invoice my customers for travel.

Is there a way to automatically add the kms when I invoice a call-out for example. At the moment we need to look at a table and this in turn leads to inconsistencies and mistakes.

Should I rather just create inventory items per customer?

Does Pastel have an option to automatically add the travel and call-out charges when I invoke say a labour charge or is everything a manual process?

Thanks.
