How long does new digital merchandising take to create and implement?

It really depends. Some of the largest catalogs we do can take over 9 months to overhaul, if there are several thousand SKUs. For catalogs that are 50-100 SKUs, the process usually takes 2-6 months. But even after a catalog overhaul, we are never finished; we always look for the competitive edge to represent the brand better and drive more sales.
