The case study involves a full-service restaurant that has different venue focus areas with seating for over 400 people. Annual sales are roughly $6 million.
The challenge here was the constant problem with accurate inventory values. From month to month, it was impossible to figure out where the inventory mistakes were made. This operation was unique in the fact that they actually had too much space for liquor, beer, and wine storage; the opposite analogy of collecting less junk when you do not have a garage space for it.
Whenever you have difficulty getting accurate inventory numbers from management, the issue is usually the organization of the bar or the setup and organization of the storage space. Restaurants that have small storage end up having fewer inventory issues and more accurate numbers because space is used efficiently. One issue is the relationship between bad inventory numbers and ordering practices – if management cannot count the bottles correctly, then how are they ordering accurately?
Here are the steps we used for this restaurant:
1. Develop an authorized product list for the bar including liquor, beer, and wine. Restrict the bar manager from ordering any items that are not on the authorized list unless he or she has discussed and ensured that it is the correct product and correctly priced. Discontinue “combo-pack” purchases from vendors.
2. Organize the bar areas with a set amount of bottles. This is setting up a par system. It is best to take the time to organize the bottles in the best manner for bartender use. Decide the number of bottles you need of each item and make this a standing par. Diagram the set up for future reference.
3. Set up a break system that only issues a bottle when an empty bottle is received.
4. Clean up the storeroom and organize it in the same order as the inventory and ordering process. These two actions are basically the same function.
By using a standard par behind your bars you can then have an accurate number of the total inventory value of the bar. You should treat each bottle as a full bottle – do not bother using the ridiculous point system; the purpose of a perpetual bar par system is the assumption that bottles get emptied and refilled continuously throughout a month and their actual state of volume at the end of a month is irrelevant over the course of a year. This system also lets you identify issues quickly when a bottle is missing from the par – it is either a theft issue or ordering issue.
