HBN Notes
Practical thinking for clearer Shopify stores.
Focused guides to the small operational decisions that shape what a customer sees, understands, and expects before buying.
Merchant guides
Start with a question from the storefront.
Do Shopify products need SKUs or barcodes?
Decide when a Shopify variant needs an internal SKU, an assigned barcode, both identifiers, or an intentional blank based on its sales and fulfillment path.
How to create a SKU naming convention for Shopify
Build a short, consistent Shopify SKU format that distinguishes variants, works with warehouse systems, and can grow without creating collisions.
How to validate GTIN barcodes on Shopify
Check Shopify barcode values for supported GTIN length, digits, check-digit errors, duplicate assignments, and the correct product-variant match.
How to check if a Shopify product is available in a specific country
Follow one product through channel publication, market catalog, online-fulfillable stock, and delivery zones for a single destination, then confirm the result with a real address.
Which Shopify products should not be published to the online store?
Separate point-of-sale, wholesale, internal, and retired products from genuine mistakes, choose between draft, archived, and unpublished, and record the decision so audits stop repeating it.
Why does Shopify checkout say no shipping rates are available?
Trace a missing shipping rate from the delivery profile and stock location to the zone, the rate conditions, and the carrier quote for the exact cart that failed.
Why does Shopify show a product as sold out when inventory is not zero?
Read the difference between on hand, committed, and available stock, then check which locations can actually fulfill an online order before changing any quantity.
How to audit SKUs and barcodes on Shopify
Review identifiers across the whole catalog, separate actionable conflicts from intentional blanks, and verify corrections before another system relies on them.
How to fix duplicate SKUs and barcodes on Shopify
Decide whether a repeated identifier is an error or an intentional workflow, then correct the affected variants without creating a second collision.
How to check a Shopify product CSV before import
Check variant rows, SKU and barcode columns, duplicate values, formatting, and live-catalog collisions before a bulk product update reaches Shopify.
