Ask the manual
Type a question and read the answer out of the user manual itself. Where the manual does not cover it, the question goes to a person.
Ask a person
A person reads every one of these and replies by email, usually within one working day. There is no machine writing answers here, and nothing is closed without somebody reading it.
If you would rather just email, support@murgese.co.uk reaches the same place. A business whose accountant supplied Murgese should ask that firm first: they hold the licence and they can see the same figures you can.
