We have a Shopify Site for our Video Game store and are considering switching to the POS for instore as our current POS won't be supported by end of year. As well as new Games/systems/collectibles we sell a lot of pre-owned videogames/systems and a few other used products, we buy theses back from our customers in trade for a store credit or cash value. The value we offer to customers for their games/products is variable based on the item, value in the market, how many we already have in overflow, as well as its condition or need for repair. We would only need the app for the POS portion of Shopify as we need to have full control of the trade process.
Unfortunately because of taxes using a normal return process won't work.
I've looked through the Shopify apps using different wording but can't find any apps for this situation. Looking through the forums I found mention of an app called Trade Orders that once existed but when I followed the link to the developers they talk about that app and it's more of a loyalty program for customers to quickly buy something without going through the regular checkout process.
Does anyone know of a work around, an app that might work, or even a developer that might be able to make this for us?
