Looking for integration with a plugin that offers Multi Tier Pricing

Hello – I am trying to do some research for a potential new client of mine.
He has multi tier pricing based on qty and he has different pricing for both Canada and USA. So your plugin handles the currency pricing based on those countries but I am guessing it would not integrate with another plugin that handles the multi tire pricing. Is that correct? And if it can – can you share with me any plugins that you know your plugin is compatible with that offer multi tier pricing. Thanks.
