We’re not sure this is the right time—what if we’re too early in our planning?

Actually, starting early is a major advantage.
It gives you the time to choose the best—or most cost-effective—suppliers, to run pilot tests on a few POS and avoid costly mistakes, to identify which locations will deliver the greatest impact, and to ensure your promotional materials are perfectly timed with product availability in-store. Planning ahead means fewer surprises and better results.
