automatically update a number in cell when template opens

I have just completed an invoice template for a new business, all works fine
but I am trying to insert a function which will automatically update a cell
number related to 'Invoice Number' each time I open the template so that I do
not have to keep trying to remember or search for the number of the last
invoice produced. Can this be done?

If your invoice number is in A1, for example, you could write a event macro
that updates the number each time the workbook is opened.
