Mining your data will take you far in predicting your sales and labor needs, but it may not cover all your bases. Factors that are a little less predictable — like a Nor’easter, for example — can catch you unprepared. In addition to monitoring the weather, Upserve advises you to keep tabs on a number of other factors that can send your business on a wild ride if you don’t prepare. At a time when delivery is on the rise, watch for promotions from third-party providers and prepare for a potential spike in delivery business when they offer discounts. Also keep an eye on local events that might bump up your foot traffic and bring in guests from out of town who wouldn’t normally be filling your dining area. Economic factors like fuel prices can have an impact, too, perhaps causing a dip in your dining room business if not business overall.
