I want to sell t-shirts with different designs that I print on demand myself. Im looking for a solution to track my inventory of blank t-shirts and accurately reflect it on my store page for each design.
I have about 100 designs set up as individual products in Shopify. Customers can choose between black and white shirts in 8 sizes each. I have set this up as variations on the product. So in total I have only 16 different base shirs in stock, but 1600 possible combinations and SKUs.
Say I have 50 blank shirts (white, size M) in stock.
When I sell 5 shirts with design A (white, size M) the stock of this specific SKU goes down to 45 as expected.
However now I only have 45 blank shirts (white, size M) left in stock, so the variation (white shirt, size M) of all the other designs als needs to go down to 45.
Essentially I need to sync the stock of specific variations across different products.
I couldn't find a way to do this with Shopify's built in functionality. Unfortunately I don't really know what to search for, so I'm sorry if this is a duplicate question.
Since I don't make a lot of revenue, are there any free or low cost solutions to this problem?
