i want seel my products online

Hi, A friend of mine who has an idol shop wants to sell his idols or products online. .. they need a platform where they can easily upload their products and sell them For example, if any customer wants a product, he should order online and make payment and after receiving the payment, he (shopkeeper) sends that product to his given address. So which platform will be best for this so that he can manage his online store according to his own Whoever wants to do the work, please tell me how all this will happen and what is the process. Note: If you have ever made something like this then share it with me so that I understand that you are the best for this project.
