Any major organizational change, whether it is to product /
service offerings, customer experience, internal processes, corporate strategy or company structure, happens
over a
span of time with impact to several roles.
Harris says that for single supplies carried out
over a period
of time spanning the change in rate, for example the preparation
of a will, the whole supply can be charged at the new rate, except where
service was provided more than 14 days before you issue the invoice.
