Where does the prescription go?

On the order itself: SPH, CYL, axis and ADD for each eye, PD, who prescribed it and the Rx date. These fields come from the Opticals pack, which sign-up does not add by itself: ask for it when you set up. When you pick a repeat customer on a new bill, Finocket offers their last prescription from earlier bills and from saved Eye prescription records, and fills only the fields still empty. The Eye prescription record type needs a setup step on your workspace; until it is done, earlier bills are the history.
