I have developed several such similar ordering website, one of the cases is 'delicious 100' ordering website, the main function of the front is the ordering function (there are others such as order inquiries, weekly menu display, customer feedback, etc.), the main development workload of such a website is in the background functions, such as rights management system, dish management and release system, delivery address management system, order processing and small ticket printing system and other functions.

If you are looking for a web company to customize and develop a website that fully meets your requirements for ordering food, the cost will not be low (order of magnitude in the tens of thousands of dollars). But if you buy an off-the-shelf developed ordering website product (which may meet most of your requirements, but not necessarily some of your personalized features), the cost will be much lower (order of magnitude in thousands of dollars).
