Step-by-step answers to the Shopify problems store owners actually hit — checkout controls, B2B net terms, subscriptions migration, loyalty points, fractional inventory, and making a catalog legible to AI assistants.
ChatGPT, Claude, and Perplexity recommend specific stores by name. How the shortlist gets built, what Agentic Storefronts does and doesn't do, the fixes that didn't work, and how to test whether changes are working.
The migration process for moving active subscribers from Recharge to native Shopify Subscriptions: exports, payment method transfer, contract creation by CSV or API, and the cutover order that prevents double-billing.
Moving customer records from a legacy CRM or platform into Shopify while preserving loyalty balances, lifetime value, and segmentation: validation, batch import, metafield storage, and the audit that proves nothing was lost.
Building a points program on Shopify without a monthly loyalty app: metafield balances, an orders-paid webhook that accrues points, a customer portal, and redemption through generated discount codes.
Two ways to give credit-approved B2B customers net 30 at Shopify checkout: native payment terms with B2B companies on Plus, or a metafield-gated manual payment method controlled by a payment customization Function.
Turning off Shop Pay Installments store-wide takes a payment settings toggle. Hiding it conditionally — for B2B customers or orders over a threshold — takes a payment customization Function on Shopify Plus. Both paths, with code.
The two Google Apps Scripts that power decimal inventory tracking on Shopify: order export processing and rounded inventory write-back, with setup notes.

Self-serve returns matured from a 2023 launch into a full native flow: return rules, customer-account requests, labels, and restocking. What it covers in 2026 and where apps still earn their keep.
Checkout extensibility replaced checkout.liquid entirely. What it is in 2026, what UI extensions and Functions can and can't touch, and what's Plus-only.
Checkout Blocks started as a third-party app; Shopify acquired it in 2024 and made it free for Plus. What the no-code checkout editor covers in 2026 — and when you need custom extensions.
The 2026 case for Shopify Plus: checkout customization, native B2B, Functions, negotiated rates, and operational tooling — plus the two situations where upgrading is the wrong call.
Shopify still tracks inventory in whole numbers in 2026. How to sell by the yard, ounce, or half-unit anyway: variant structure, pricing math, and automated decimal tracking.
Where Shopify's express checkout buttons actually come from in 2026, how to turn each one off, and how to hide them conditionally with checkout customization.
