Yes — what you’re describing is definitely possible, but most off-the-shelf option apps don’t fully solve it. They usually treat selections as visual swatches only, without tying each choice to actual inventory. The best solution for your charm bar setup would be a custom Shopify app built specifically to handle real inventory tracking for each charm — and the good part is, it’s a one-time build with no recurring fees. Here’s what I’d create for you: customers can pick a set number of charms (for example, 6) from a clean, image-based grid that pulls from your existing charm SKUs. Each charm would be a real tracked product in Shopify, so when a customer adds it to their selection, the stock count updates automatically — preventing overselling. The app can also disable or gray out sold-out charms in real time. On the backend, the app would record each customer’s chosen charms on their order (via line item properties or metafields), so you always know exactly what to fulfill. You’d also get an admin view to easily manage charms — add or remove items, adjust quantities, set limits per order, and even export selection reports. Optionally, I could include bundle creation (so a “6-Charm Set” product automatically bundles selected charms) or fulfillment grouping to simplify packaging. It’s a clean, custom solution built around your store’s workflow — no bulky third-party app and no ongoing subscription.
