Add Multi-Store Functionality To An Plugin

Our carrier has developed a plugin to add and print shippinglabels, add track&trace and more. However, multistore isn't supported by the plugin. I know it's a bit of a general question, but how much work would it be to add multi-store functionality to an already existing plugin?

Hello!

It is hard to answer this question without the examination of add-on functionality. The cost depends on what is not working now and how it should work for multiple storefronts.
