first of all, it's very good for you to operate in good faith, so that you can do business for a long time.
besides, your store has just opened for a few days, and I think it's very good to save a few now. It is impossible to make a lot of money in business at once now, so you should calm down and stick to it.
There are still a few questions you need to sum up: 1. Store location; 2, facade decoration, which determines whether your store can attract customers into the store, I think you can make a conspicuous advertisement on the facade: new store opening, discount promotion of certain products, so as to attract customers into the store to understand your store, and then form a stable passenger flow; 3. How are the local contacts? I don't know whether you are a retailer or a wholesaler. If you are a wholesaler, you must have a certain network base to become a stable sales channel for your store. Of course, it doesn't matter if you don't have any connections yet, just build them slowly.
I wish you a prosperous business!
