Just some shitty code to make cash usable. No support will be given, if you have any problems, please feel free to make feature-issues to the QBCore crew to make this themselves.

qb-core/server/player.lua

Code to automatically update cash from playerdata to items

Citizen.CreateThread(function()
	Wait(10000)
    exports['oxmysql']:execute('SELECT * FROM players', {}, function(result)
		for k, v in pairs(result) do
			local Player = QBCore.Functions.GetOfflinePlayerByCitizenId(v.citizenid)
			if Player.PlayerData.money.cash > 0 then
				table.insert(Player.PlayerData.items, {
					info = "",
					name = "cash",
					slot = (#Player.PlayerData.inventory + 1),
					type = "item",
					amount = math.floor(Player.PlayerData.money.cash + 0.5)
				})
				Player.PlayerData.money.cash = 0
				QBCore.Player.SaveOffline(Player.PlayerData)
			end
			Wait(100)
		end
	end)
