A retool doesn't have to mean gutting the store. Most owners start with the machines that break down the most, or with card and app payments so customers stop needing quarters.
The lease comes first in a retool too. Equipment financing usually needs a lease that runs at least as long as the loan, so check your remaining years — including options — before you price out machines.
From there it's about fit: how many washers and dryers you have now, how old they are, and what your customers keep asking for. A plan built around your store's real volume beats a generic package every time.
