Make sales at store

Hello, How Could I do sales at store ? I need option for realize sales on point of sales. Could I do it without plugins?

What do you want to do ?
Do you mean use nopCommerce as a point of Sale system ?
If so there is a plugin https://www.nopcommerce.com/point-of-sale-plugin

You don’t to have to make plugins to customise the solution - you can just start cutting code. But If you plan to provide the code or functionality to someone else or sell it in the marketplace then it is best to make plugins. Plugins make it easy to keep the code together in one package so that it can be easily built, managed and updated for use in upcoming versions of nopCommerce.

The plugin removed, why?

Please advise if I can build point of sale plugin using payment method cash and credit?

They probably have not updated to use the new rules for plugins in the marketplace
