Recharge vs Appstle Subscriptions: the 19¢ that turns 1.49% into 3.07%
Recharge's Starter plan is $99/month plus 1.49% and 19¢ per transaction. The 1.49% is the number every comparison article quotes; the 19¢ is the number that decides what you actually pay. On a $12 refill order the two fees together come to 3.07% of the order, not 1.49%. Appstle℠ Subscriptions charges 0% per transaction but caps each flat-rate plan by monthly subscription revenue — $500, $5,000, $15,000, $100,000 — which is why the widely repeated claim that a $50,000/month store pays Appstle $360 a year is wrong. Recharge's $25 plan is closed to any store that installed before February 9, 2026, and the counter that pushes you off it never goes down. Recharge's own help center still quotes the old 1.25% rate, and Appstle's still describes its tiers by subscription count instead of revenue.

Every Public Shopify App Has Until January 1, 2027 to Change How It Logs In — and Shopify's Own Guide Says the Ones You Never Open Can't Fix Themselves
Shopify's developer changelog of May 20, 2026 set a hard date: on January 1, 2027, public apps still using non-expiring offline access tokens start getting authentication errors on the Admin API. For most apps this repairs itself silently — Shopify's migration guide says existing tokens cycle the next time each merchant opens the app. The guide then names the exception in its own words: it never covers an app that merchants don't open, and it lists webhook consumers, App Proxy backends, and Flow actions. Those are exactly the apps you installed once and never launched again. The word 'token' appears zero times on all six App Store listings checked for this article, so the listing can't tell you which apps have migrated. One page in your admin can tell you something better. Verified against Shopify's changelog, developer documentation, and Help Center on September 11, 2026.
Shopify's Guide to Switching Themes Lists Five Things You'll Lose. App Blocks and App Embeds Aren't on It.
Publishing a new Shopify theme turns off every app block and app embed you had configured. Shopify's 'Adding, previewing, and buying themes' page — the one merchants actually read before switching — lists five theme-associated items and never uses the words 'app block' or 'app embed'; the warning lives on a different page entirely. The reason is mechanical: shopify.dev documents that app blocks are written into template JSON files and app embed activations into config/settings_data.json, so a new theme starts with neither. Judge.me, Loox, Vitals, Klaviyo, PageFly and Tidio all publish theme-change instructions, and they split into apps that detect the problem for you and apps that expect you to notice. The failures that cost the most are the quiet ones: Klaviyo's Viewed Product and Active on Site events ride the app embed, while Added to Cart keeps flowing from a Shopify pixel, so the dashboard never goes to zero. And the one mechanism that always survived a theme switch — script tags — stops running on March 1, 2027.

Shopify Caps Apps at Five Usage Meters. Vitals Uses All Five — and Two of Them Bill You on Sales It Says It Caused
Shopify's own documentation sets the ceiling: an app can run at most five usage meters per plan, at most six pricing tiers per meter, and 'usage caps aren't currently supported.' Vitals — the $29.99 all-in-one app with a Built for Shopify badge and 2,953 reviews — runs exactly five meters at exactly six tiers. Two of them bill on 'assisted sales attributed to Vitals,' a number Vitals computes and you cannot audit, and at Tier 6 every extra $10K of attributed sales adds $100. Vitals' App Store listing names two metered things; its own pricing page lists five. Its Help Center's entire Billing & Charging section, last updated April 10, 2026, mentions none of them. Meanwhile three of the five meters bill for things Shopify Forms, Shopify Messaging and Microsoft Clarity give away. Compared against Growave, which meters orders instead.

A Shopify Customer Segment Can't Contain a First-Time Buyer — and the Apps That Fix It Redefine 'First-Time' Four Different Ways
Shopify's discount Eligibility field has exactly four options — All customers, Specific customers, Customer segments, Markets — and none of them is 'first order.' The standard workaround is a segment of customers with number_of_orders = 0, but Shopify's own Help Center says a segment discount 'applies only to existing customers' and that a first-time buyer 'won't be included in the customer segment until after their first order is complete.' So the workaround excludes the exact person it was built for. Six real apps answer the question instead, and each one quietly substitutes a different proxy: account registration, first login, a customer tag evaluated in Shopify Functions, 'purchase history,' or a device-fingerprint identity graph filed under Fraud rather than Discounts. Compared on what actually triggers the discount, what happens at guest checkout, and USD pricing: FirstTime Discount, New Customer Discounts, UR: Register Product Discount, Regios Automatic Discounts, Bony Automatic Discount App, and OverlayIQ. Plus the July 30, 2026 Shopify Functions field that looks like the fix and has the same blind spot. Verified September 10, 2026.
A Shopify App Store Search Page Has Up to Four Slots That Were Auctioned Off. A Logged-Out Browser Can't See Any of Them.
Searching the Shopify App Store for 'email marketing' returns 3,880 apps, and you see about twelve. More than one mechanism decides that order. shopify.dev publishes the slot counts — four ad placements on a desktop search page, three on mobile — and prices them through a CPC first-price auction that runs on every single search. The Help Center states plainly: 'You can't opt out of ads on the Shopify App Store.' Yet on September 16, 2026, a logged-out en-US browser found zero 'Ad' labels across search, category, and homepage. That matches the spec: ads don't show to merchants who already installed the app, to stores that fail its installation requirements, or over a VPN, and Built for Shopify plan targeting only reaches merchants who are logged in. The organic remainder isn't a quality ranking either — the app with 7,739 reviews sits third, the only 5.0 sits fifth, and switching the display locale changes the order from position four down.

Shopify Now Sets US Sales Tax From the Location Your Routing Rules Pick. In 12 Jurisdictions, a Stockout Can Change the Rate.
On August 24, 2026 Shopify changed how US sales tax is sourced: tax is calculated from the fulfillment location your order routing settings select for each order, and local pickup is taxed from the pickup location. The changelog URL says it plainly — shopify-tax-is-now-compatible-with-order-routing. We expanded all 52 entries in Shopify's US taxes reference and counted the sourcing field: 10 origin, 2 hybrid, 36 destination, 4 not applicable. That is the exact blast radius. Inside it, the routing rule Shopify puts first by default falls back to the location holding the most available inventory — so stock levels become a tax input. Meanwhile every order routing app reassigns the location after checkout, and Shopify documents tax recalculation for a changed shipping address but not for a moved fulfillment location. Four apps that shift your ship-from location, with verified USD pricing. Researched September 14, 2026.
Shopify Won't Let You Write a Note on Your Own Sales Chart. It Will Let 51 Kinds of Note Be Written There by Your Apps.
Shopify launched analytics annotations on May 5, 2026 with six event types, all generated by Shopify itself and described as 'nothing to configure.' By July 24 the same layer was open to third-party apps, and an app holding the write_analytics_annotations scope can now create 51 of the 57 types — including capital_funding, team_change, award_recognition and attribution_change, none of which are scoped to what the app actually does. The Help Center states the asymmetry plainly: 'You can't create or add your own annotations manually.' Titles cap at 75 characters, descriptions at 150, and the per-app limit is real but unpublished. Meanwhile Shopify-generated annotations only appear if your store averages 10+ orders per week for 12 non-consecutive weeks in the past 6 months — so on a smaller store, every marker on the chart came from an app. Verified against shopify.dev, the Shopify Help Center, changelog.shopify.com and live App Store pages on September 16, 2026.
