Using the previous top-line details from the
current utility bill, the sales person will then be presented with a
choice of valid tariffs automatically. Again, the handheld will
calculate valid tariffs for the meter details and prevent mistakes in
a tariff calculation. The handheld will validate acceptable
consumption figures for the meter type, valid date entry etc.
The sales person simply has to enter current consumption figures for a
previous period e.g. from the clients present utility bill and the
handheld will automatically calculate the cost of providing energy to
the client on the following screen.
