jEEpersShops is a serverside fabric/forge mod that adds shops that can be used with commands
This mod requires a mod that uses the OctoEconomyAPI, I only know of EightsEconomyP as the mod that implements the API, you can find it here.
To get started, do /shop create or /shop open as the owner. After that, you can begin inserting items into the shop with /shop insert <price> while holding the item you want to put in the shop.
If you want to look at another players shop, you can do /shop open <playername>, and this works if the player is online or offline.
To purchase an item, click the item in the shop, and it will open a new menu where you can either confirm your purchase, or cancel and go back.
If you are the owner of a shop when you click the item it will open a new menu, where you can confirm the removal, or cancel and go back to the main shop menu.
