Anonymized case studies from a Shopify Plus developer — real merchant problems (B2B, Subscriptions, Functions, shipping, loyalty, agent readiness) broken into four-piece sketches with runnable code.
A supplement brand wanted its wholesale customers to subscribe to automatic repeat orders and be billed their wholesale price every time — but Shopify's native Subscriptions only knew retail pricing. …
I'd build this as a four-stage migration flow. First, validate the legacy export for format, duplicates, and Shopify compatibility. Then batch-import customers and apply tags through the Admin API. Th…
I'd build a targeted delivery customization Function that reads a managed blocklist of known problem zip codes and hides Saturday delivery in only those addresses at checkout. The core is a small admi…
I'd build a four-piece system: an admin UI extension to select and tag orders for batch processing, a template builder to let them define which fields appear on each slip, a backend service that rende…
I'd build a carrier-cutoff system that compares the current time to the merchant's 2pm CT fulfillment window, then renders dynamic ship promises on the storefront. The PDP shows "Ships today, arrives …
I'd build a chatbot backend that syncs Shopify orders on a schedule and exposes them via a retrieval-augmented chat interface. The merchant embeds a chat widget on their storefront, customers ask ques…
I'd build a scheduled digest that fires every morning at 7am. The system pulls yesterday's metrics from your sales data, forecast model, shipping logs, chat system, and tax reconciliation ledger—write…
I'd build a lightweight autonomous monitoring service that runs on a schedule and polls each critical node in the infrastructure—Heroku dynos, carrier APIs, product sync timestamps, and tax records—co…
I'd build this as a four-part system: generate a unique referral code per customer and store it in a metafield so they can share it; use Shopify Flow to tag new customers who arrive via that code and …
I'd build this as a custom app with a Shopify order webhook that fires on payment capture, a theme extension portal for customers to check balances and redeem, and the Discount API to generate codes o…
I'd approach this as a four-phase build: pull the product catalog and inventory via WooCommerce's REST API into Shopify using the Admin GraphQL, store the original WC product IDs as metafield referenc…
I'd build this as a multi-store sync problem, not a single-store problem. The merchant keeps two Shopify stores (one US, one CA) running in parallel, but stitches them together at three critical momen…
I'd use a Payment Customization Function to enforce the rule at checkout, then layer in a disclosure badge so customers understand why installments aren't available. To keep the system clean, I'd add …
I'd build a cart-validation Function that runs at checkout and blocks orders when subscription items are mixed with one-time purchases above the threshold. The merchant would tag subscription products…
I'd build a Cart Transform Function that reads bulk pricing tiers stored on each product's metafield and applies the right discount instantly at checkout. On the storefront, I'd add a tier preview wid…
I'd build a checkout hook that catches zero-rate responses from the primary carrier, triggers an instant backup carrier lookup, and fires an alert if both fail. Then I'd surface those gaps in a dashbo…
I'd build this as a Shopify Function that fires the rate engines in parallel and returns whichever responds first—or falls back to Shopify's native rates if ShipEngine times out at 800ms. That way the…
I'd build a three-layer gate: first, a Liquid tag check on the collection template itself that throws a 404 for anyone without the b2b tag trying to access restricted handles; second, hide those colle…
I'd build this in layers: first, a B2B Companies structure in Shopify where each wholesale buyer is tagged with their tier and company ID. Then a Shopify Function that reads that company ID from the c…
I'd use a customer metafield to flag credit-approved B2B accounts, then hide the payment step in Checkout Extensions for those customers. The storefront would display net 30 terms prominently, and Sho…
