Key Assignment Draft

Brian Miller is an entrepreneur. He started a small-town friendly grocery store. People stopped by his store to pick up things they did not want to run to the regular grocery store for. In 3 years, because of popular demand, he started adding more items on his shelf and pretty soon, he had grown into a regular grocery store. People loved his store because he knew everyone by their first name and would try to fulfill everyone’s requests. He now needs some help with his inventory. He hired a CPA firm that would give him some advice on how he should maintain his inventory.
