Pharmacies in Africa struggle with access to finance, but inventory management is really what bogs them down. How do pharmaceutical retailers know how much stock they need? How do they know which products to stock at a given time? How do they know what products aren't selling?
At the moment, there's not enough data to answer these questions. Cash gets tied up; there are more or fewer products than are needed at a particular time. If it's the former, they run a risk of selling expired products. If it's the latter, patients can't get what they need.
