Handling 60 SKUs of similar products is a big problem. Multi-variant stock control and supply chain management is troublesome at best. If one of your stores runs out of green widgets and another one only has red widgets until Tuesday, how do you reliably sell red and green ones to customers who want one without buying so much stock that you are then at risk of a loss when it is end-of-lined? Too late, the customer has gone to another widget stockist. (I did a lot of work in supply chain management a few years back).
