Have you outgrown Shopify?

Outgrowing a platform is a success symptom, not a failure. But the signals are easy to misread — and most “time to replatform” advice is written by people who profit from the answer.

We’ve published a diagnostic instead of a pitch: seven specific signals, each with an honest fix you can apply where you are, and the exact threshold where workarounds stop paying for themselves. Calculated pricing. Product models that don’t fit. Checkout as a constraint. App-stack sprawl. Fulfilment routing. Integration ceilings. Control over your AI agent surface.

There’s a printable scorecard at the end. Score each signal 0–2. Under 5, stay put and go fix something that moves revenue this quarter. Over 10, the workarounds have become the system.

Every capability claim is checked against current platform documentation — and we corrected two of our own previously published positions along the way.

Five things worth your attention

1. AI traffic isn’t just growing. It’s converting better than the rest.

AI referral traffic to US retail rose 393% year-on-year in Q1, measured by Adobe across more than a trillion visits. The more useful number: by March, AI-referred traffic converted 42% better than non-AI traffic, having converted 38% worse a year earlier — an 80-point swing in twelve months — with revenue per visit running 37% higher. Meanwhile OpenAI shelved ChatGPT’s Instant Checkout in March after five months and roughly a dozen live Shopify merchants. ChatGPT now surfaces products and sends shoppers to your checkout: you keep the transaction, it keeps the discovery. Adobe via TechCrunch, CNBC

2. The agent protocol stack is settling — and it’s layers, not a war.

Five standards get quoted as rivals, but most of them stack rather than compete. AP2 handles authorisation — Google donated it to the FIDO Alliance in April. Visa’s Trusted Agent Protocol and Mastercard’s Agent Pay sit on the payment rails. The one genuine contest is checkout: ACP (OpenAI and Stripe) versus UCP (Shopify and Google, launched at NRF in January with twenty-plus partners including Walmart, Target, Etsy, Visa, Mastercard and Amex) — and momentum currently sits with UCP. Structure your product data well and stay portable.

3. Two platform deadlines land this month.

Shopify script tags on the Thank you and Order status pages stop working for non-Plus stores on 26 August — if anything post-purchase still relies on them, it breaks. And Magento 2.4.5 and 2.4.6 leave support on 11 August.

4. The EU’s €150 duty exemption is already gone.

It ended on 1 July. Parcels under €150 now carry a flat €3 customs duty per tariff heading, with items sharing a classification grouped onto a single line. A separate EU-wide handling fee of roughly €2 per consignment is expected from around November, and standard tariffs replace the interim €3 later. If you ship direct to EU consumers this is a live cost today, not a Q4 planning item. Avalara

5. Value-seeking shoppers spend more, not less.

Deloitte surveyed 1,207 US parents in late May: 71% will switch brands if their preferred one is too expensive, and 31% are running four or more cost-saving behaviours — yet those value-seekers plan to spend 14% more than everyone else. The number worth pinning up is the discovery gap: average planned basket was $381 for parents using no digital tools, against $737 for those using search, social and gen AI together. Prime Day told a similar story — a record $8.3bn in the first 24 hours, up 5.3%, on smaller orders. Deloitte
