How to deal with inventory in two locations

There are products in the store that have inventory in multiple locations. My not-so-great solution was to list those products twice with an acronym added to the name to indicate the location. The client didn't like that solution because it's confusing to have the same product listed twice and the people ordering don't care which location it's coming from. I installed the inFlow software in the site, but it's $219 a month which is a huge cost that we can't justify. Are there any other solutions for managing inventory in two locations? Thanks
