The catering industry has a long history. I believe that every shopkeeper has an "abacus" in his head to calculate the operation of the store at all times, but most shopkeepers really just keep the "abacus" in their heads, which is why in the catering industry, everyone has always heard such a puzzle: "One store makes a profit, three stores are tied, and if this continues, it will be a loss." It is difficult to calculate and coordinate the profits of so many stores with only one person's brain power. It's time to use more scientific means to let computers help plan business. Although computer business needs a cost model, different catering industries have different cost models. But I think the essence is the same. There are four important nodes in the catering industry, namely "purchase, sale, storage, management and operation". These data are not difficult to obtain. Require front-line employees to keep records in place, and purchase and sale data can fall on paper. With the basic data, most stores only do monthly summary, ignoring the whole process, so many potential profit and loss improvement points are missed. For example, a shopkeeper always finds that the amount of goods purchased this month is far greater than the sales volume, but there is no way to trace the reason. Only when a shopkeeper made a monthly summary, garlic was at the lowest price in history last week, but it failed to stock up in time. Now it has risen back, and it is too late to regret it. To find these opportunities, it is too difficult to rely only on the monitoring and calculation of the human brain. A better way is to let the computer help record the data and give an analysis. 20 14 internet take-out and food delivery O2O goes to war. At that time, the boss of a donkey fire told me that the starting subsidy for each platform order could reach 12 yuan, while his donkey fire was originally 12 yuan. The boss had to increase the price to 15 yuan to avoid the explosion of the order. What's more, there was more than one platform subsidized at that time. Catering businesses have thus opened the road of multi-platform take-out, but businesses love and hate the situation of multi-platform take-out. I love the opportunities brought by the take-away platform, but I hate the need to maintain goods, handle evaluations, declare vacancies, carry out activities, check accounts, adjust inventory ... and even calculate how much money I sell on multiple platforms every day. That's called tiredness. However, this form has also made the stores that were used to monthly summary begin to pay attention to the daily traffic and the passenger flow of various take-away platforms. The rise of the Internet goods selling industry has forced shopkeepers to move towards the road of digital operation.
