Shopify Plus Gives You Nine Extra Stores and Exactly One Chance to Copy Data Into Them
Shopify's Help Center says it in one line: store settings, products, collections, and inventory aren't synced between stores, and points merchants at third-party apps or an ERP. The data import only runs at store creation — after that you manage it manually, and it never included category metafields. Meanwhile the App Store's own Multi-store filter in the Inventory sync category returns all 521 apps, unchanged. Five real multi-store sync apps compared, metering on five different units: imported products, products per connected store, variants, multi-store products, and feeds plus schedule frequency.

Two Shopify Stores, One Catalog: The Identical Sync Job Costs $10 or $119 Depending Only on Which App You Install
Shopify syncs nothing between two stores you own. Locations live inside one store, Markets serve many countries from one store, and Shopify Collective is a dropship relationship with a 100-variant cap that zeroes your inventory when you uninstall it. So multi-store sync is an app decision — and the six real apps meter six different things. Syncio charges the destination for products and the source for orders. Tipo charges for every variant in the destination store, including the ones you never sync. Synkro's $25 plan is $25 per connected store. Trunk bills a rolling three-month order average across all your channels. Priced against one identical two-store setup, the spread runs from about $10 to about $119 a month.

Shopify Cannot Split a Payout — and That Is the Real Cost of a Multi-Vendor Marketplace
Shopify's Vendor field is a text label next to Tags. Staff seats stop at 0 on Basic, 5 on Grow, and 15 on Advanced. And Shopify Payments has no split-payout construct at all — so every multi-vendor marketplace app you can install is a ledger, not a payment rail. We priced five real marketplace apps from the US App Store on September 2, 2026 and found their monthly fees meter on four different units, which inverts the cheapest-app ranking between a 25-vendor store and a 100-vendor one. The bigger number is the one none of them charge you: Puppet Vendors' own help center documents that PayPal Payouts costs $0.25 per US payout and requires an approval that PayPal can deny outright, and that money from Shopify Payments never reaches your Stripe Connect balance because Shopify runs a managed Stripe account.
Shopify Already Ships 3D and AR for Free — What You Buy From Apps Is Either a Model or a Mirror
Shopify natively accepts GLB and USDZ product media up to 500 MB, converts every upload to both formats so iOS and Android both work, auto-optimizes anything over 15 MB, and lets shoppers place the item in their room with the device camera — at no cost and with no view cap. Merchants shopping for a 3D/AR app on September 2, 2026 are usually buying one of two things Shopify does not do: someone to build the 3D model, or face, hand, and body tracking so the product appears on the customer rather than on the floor. We compared seven apps in the US App Store. Touchtry Virtual Try On starts at $199/month and meters AR views; Angle 3D Configurator and ARDisplay state unlimited views; GlassOn charges $1 per human designer adjustment; and the free GlassOn Starter plan expires after two months.
Shopify Has Two Native Deposit Systems. One Is Plus-Only, the Other Is Documented as Unusable With It — and Four Apps Bill the Gap Four Ways
Shopify can take a percentage deposit and collect the balance later, natively, in two different ways. B2B payment terms do it with a deposit requirement — and Shopify's help center states plainly that deposit requirements are available only on the Shopify Plus plan. Deferred purchase options do it through selling plans, on every plan, but shopify.dev lists the walls: no draft orders, no B2B, no POS, no local payment methods, no cart permalinks, no checkout.liquid, one deferred due date per order, and only four payment gateways. Shopify vaults the card; collecting the balance and handling declines is explicitly the app's job. That job is what you buy. Downpay, SPD, Depo, and DP price it by processed order value, by processed order value at four times different thresholds, by a per-transaction percentage on top of a subscription, and by nothing at all. At $50,000 a month the spread is $99 to roughly $399. Researched September 2, 2026.
Shopify Forms Can't Branch — and the Six Quiz Apps Don't Count "a Response" the Same Way
Shopify's own documentation closes the door on building a product quiz natively in two sentences: "Multi-step forms aren't supported" and "Conditional logic isn't supported on forms." Native recommendations cap at ten products per surface and the Storefront API returns at most ten. So every real product quiz on Shopify is an app, and every app meters you by a unit it defines itself. We priced six on September 2, 2026 and found entry tiers of 200 to 600 units for $9.99 to $59 — but Lantern bills a "quiz taker" the moment someone answers one question, Octane AI bills credits where AI features consume extra fractions per quiz, and Quiz Kit's "Free" plan is development stores only. Cost per response ranges from $0.05 to $0.125, and the cheapest headline is not the cheapest bill.
Re-Upload One Lesson Video and Every Past Student Loses Access — What Shopify's Free Digital App Does to a Course
Shopify Digital Products is free, has a 5 GB file limit and — unusually — no bandwidth limit at all. That makes it a genuinely good file-delivery tool and a bad course platform, for reasons its own help page states: edit or delete a file and previous buyers lose their download link, links can only point at 12 named providers including Teachable and Thinkific, and every click of one counts against the download limit. The four apps that fix this meter on four different things — lessons, students, enrollments, or gigabytes — and for a 50-student video course the answer ranges from $29 flat to $354.99.

Shopify POS Offline Can't Sell a Gift Card, Honor a Discount Code, or Take a Return — and Logging Out Can Lose the Orders
Shopify publishes an exact list of what stops working when Shopify POS loses internet, and it is longer than most retailers assume: no gift cards in either direction, no discount codes or automatic discounts, no returns, exchanges or voids, no tips, no customer lookup or creation, no saved carts, no ship-to-customer, no BOPIS fulfillment. Manual discounts and cash still work. Offline card payments are a separate opt-in feature with two limits you set yourself, a staff permission, an app-version floor of 9.14.0, and a list of things that are excluded — Tap to Pay on iPhone and Android, swipe, MOTO, Interac in Canada, eftpos in Australia, and every retail location in France. Shopify also tells you to ask app developers whether their POS apps work offline. We checked ten POS-relevant listings, including Shopify's own. Not one of them mentions offline.
