Shopify Inbox Can't Receive Email — And Its Instagram, Messenger, and Shop App Channels Were All Discontinued
Shopify Inbox is free, well-built, and handles exactly one channel: the chat widget on your own storefront. Messenger and Instagram integrations are gone, Shop app chat was retired February 19, 2025, and the help center states plainly that Inbox agent can't send email on your behalf — the customer has to start it. The bigger surprise is on the paid side: five helpdesk apps meter on five different units, and Gorgias's AI Agent adds $0.90 per resolution on top of the plan, which is $1,350/month at 3,000 tickets and 50% AI resolution. Break-even math by volume, calculated from published pricing on September 1, 2026.
Shopify's Native Packing Slip Has No Money Variables at All — What It Takes to Produce a Compliant Tax Invoice
Without an app, Shopify prints exactly two things: an order summary and a packing slip. And the official packing slip variable reference contains no variable for price, tax, subtotal, or total — not one. Install the free first-party Shopify Order Printer and the default invoice template emits tax as one combined line via order.tax_price, with no per-rate breakdown and no issuer registration number. That's why an EU VAT invoice and a Japanese qualified invoice both require either template surgery or a paid app. Seven invoicing apps compared across 16 identical axes, verified September 1, 2026.
Legacy Customer Accounts Are Deprecated — Six Things That Don't Survive the Upgrade
Shopify deprecated legacy customer accounts on February 26, 2026, with a final sunset date to be announced later in the year. Seven features only exist on the new version. Six things cannot be carried over — including Flow workflows built on legacy accounts and any segment using customer_account_status, for which no replacement filter exists. Here's the full boundary, and what has to be rebuilt as app blocks. Researched September 1, 2026.
Shopify Ships WhatsApp Natively and Leaves LINE Out — What That Costs You in Japan
Shopify Messaging supports email, SMS, and WhatsApp. LINE appears nowhere — not in Messaging, not in Campaign Autopilot's channels, not in the sales channel list. And the common claim that Shopify Plus merchants can wire up LINE Login as their identity provider doesn't survive contact with the specs: Shopify requires an email_verified claim that LINE's ID token doesn't contain, and rejects HS256 signatures, which is exactly what LINE returns for web login. Here's the three-layer reality of LINE login on Shopify, the two-tier cost structure nobody quotes, and five real integration apps compared. Researched September 1, 2026.
Before You Pay a Shopify App to Generate llms.txt — Shopify Already Serves It, and Google Says It Ignores It
The Shopify App Store now has AI search optimization apps priced from $29 to $299 a month, and llms.txt generation is their headline feature. But Shopify's help center states that every Shopify store automatically serves /agents.md and /llms.txt, and that "you don't need a third-party app to generate these files." Google's own documentation says llms.txt files aren't needed for Search and won't help or hurt your rankings. OpenAI, Anthropic, and Perplexity make no mention of llms.txt in their crawler docs at all. Here's what's worth paying for and what isn't. Researched September 1, 2026.
Shopify Warns That Currency Converter Apps Break at Checkout — Here's What Actually Controls Local Currency
Selling in local currencies on Shopify requires Shopify Payments or Adyen. Without one, an app can change what the price says but checkout still charges in your store's default currency — and Shopify says so in its own Help Center. The conversion fee splits 1.5% / 2% by store location. Manual rates cannot be applied to your primary market and are ignored on refunds, where the original conversion fee is never returned. And markets on a shared domain are not indexed by search engines at all. Researched September 1, 2026.
Basic, Grow, and Advanced All Cap at 10 Locations — But 3PL Apps Don't Count Against It
Shopify's active location limit is 2 on Starter and 10 on Basic, Grow, and Advanced alike. Paying more doesn't buy you more warehouses — the next step up is Plus, at 200. But Shopify's help center adds a line most merchants miss: locations created by dropshipping apps, 3PLs, and custom fulfillment services are treated as locations yet don't count toward the limit. That's a real escape hatch, with real conditions. Plus the order-routing default that surprises people: Shopify does not ship from the closest location unless you tell it to. Eleven inventory and fulfillment apps compared, researched September 1, 2026.
Shopify Magic Writes Real Liquid Into Your Theme — and Nobody Will Support It
Shopify Magic is free on every plan, but the help center immediately adds that access to specific features may vary — and it means it. AI theme generation is documented as available only on free trial, Basic, Grow, or Advanced, and only when your storefront is set to English; Plus isn't in the list. AI theme block generation has no such language condition and writes a genuine .liquid file into your theme's blocks folder. But Shopify states plainly that neither Shopify Support nor third-party theme developers will help you troubleshoot that code. That single line is the real dividing line against page builders. Seven builder and section apps compared on pricing, AI features, and uninstall behavior. Researched September 1, 2026.
