Shopify Validates Addresses for Free — and Tells You Not to Run an App Alongside It
Shopify's admin address validation is on by default, free, on every plan, and supports the US. Checkout-time validation is one toggle away. Shopify's own documentation then warns that running a third-party address validation app at the same time can create conflicting suggestions and reduce checkout conversion — you are meant to pick one. That reframes the whole category: apps are not there to duplicate deliverability checking, they are there to enforce policy Shopify's validator does not enforce, like blocking PO boxes or requiring an apartment number. We priced four real apps from the US App Store on September 2, 2026, spanning $4.99/month flat, $0.04 per order, and one that requires a separate subscription billed outside Shopify.
Going Headless Breaks Exactly Two Kinds of Shopify App — and Shopify's Own Headless App Collection Lists About 30
"Do Shopify apps work with Hydrogen?" is the wrong question. Shopify's own App surfaces documentation lists seven places an app can live, and going headless removes exactly two of them: theme app extensions and web pixels. Everything else — Shopify Functions, checkout UI extensions, admin extensions, POS, Flow — keeps running, because Hydrogen still hands the buyer to Shopify's hosted checkout through cart.checkoutUrl. Shopify also curates a collection called Apps that enhance your custom storefront: it holds about 30 apps, the exact set varies by session, and the categories missing from it tell you more than the ones in it. Surface-by-surface breakdown, the full list, and the consent setting that silently kills Hydrogen analytics. Researched September 2, 2026.
Shopify B2B Has No Request-a-Quote Workflow: What a Draft Order Actually Does, and Which RFQ App to Buy
Shopify B2B ships company accounts, catalogs, and net terms, but it has no request-a-quote workflow. The closest native object is the draft order. This article settles exactly what a draft order does and does not do: custom line-item prices yes, payable invoice link yes, automatic inventory reservation no, buyer counter-offers no, invoice expiry not published. It also corrects the outdated claim that Shopify B2B is Plus-only — as of September 2, 2026 the Help Center states B2B runs on Basic, Grow, Advanced, and Plus, with only direct company catalogs, deposits, partial payments, and contextual experiences gated above Basic. Then it compares five live RFQ apps on the one question that decides the operational outcome: whether the quote becomes a native Shopify draft order, whether the buyer can pay from it, and whether the app understands B2B company accounts and catalog price lists at all.
Shopify Checkout Customization Without Plus: The Gate Is Per Page, Not Per App
Shopify Plus is not required to customize checkout — it is required for three specific pages. Shopify's availability table gates UI extensions on the information, shipping, and payment pages behind Plus, while the Thank you page, Order status page, and all customer accounts pages have been open to Basic and higher since May 21, 2024. Public apps built with Shopify Functions run on any plan; only custom apps need Plus. But in the US and Canada, payment customization on a non-Plus plan cannot touch the credit card fields, and post-purchase offers never appear on Apple Pay, Klarna, Affirm, AfterPay, Amazon Pay, Google Pay, or gift card orders. Every legacy workaround is gone: checkout.liquid and additional scripts sunset August 28, 2025, non-Plus script tags August 26, 2026, Shopify Scripts June 30, 2026. Seven real apps compared, with prices and ratings verified September 2, 2026.
Shopify Has No Donation Feature — and "100% Goes to the Charity" Means Three Different Things
Shopify has no native way to collect a customer donation or a round-up at checkout. The closest built-in feature is Tipping, and Shopify's own help center suggests relabeling it "Donations" — but tipping caps at $1,000, breaks with Shop Pay Installments, isn't supported by the Subscription API, and has no charity, no disbursement, and no receipt. So merchants install an app, and that is where the real decision hides. We read the terms and help centers of five donation apps on September 2, 2026 and found three incompatible answers to one question: who is the donor of record. ShoppingGives issues the donation receipt to the merchant, Pledgeling Foundation emails it to the shopper, and DailyKarma tells shoppers they will not get a charity receipt at all. The fee models differ just as sharply — on $1,000 of monthly donations, the charity receives $1,000, $841, or $870 depending on which app you picked.
