Expanding to International Markets on Shopify: What They Don't Tell You

One store with Markets vs. two separate stores

Shopify Markets lets you sell to multiple countries from a single store with localised pricing, currency display, and language. This sounds ideal and it works well — to a point.

The limitations hit when you need fundamentally different product catalogues (different SKUs for UK vs. US, different size systems, products legal in one market but not another), different marketing infrastructure (a UK Meta Business Manager, a UK pixel, UK-specific campaigns), and different operational SLAs.

Two stores — one per market — gives you complete isolation: separate Analytics, separate pixels, separate checkout flows, separate inventory. It's more expensive to run but cleaner to optimise. For brands doing significant volume in two markets, two stores is almost always the right call. Below that threshold, Markets is usually sufficient.

The currency and pricing problem

Displaying prices in local currency is a hygiene requirement for international customers — they will not buy if forced to calculate from your base currency. But "show price in local currency" is not the same as "have a good pricing strategy."

FX rates fluctuate. If you set your UK price at a fixed GBP amount and the FX rate moves 8%, your margins compress. You need a pricing review cadence — ideally quarterly — that reassesses your local currency prices against your target margin.

Duties and taxes are the other trap. For UK customers buying from abroad post-Brexit, orders over £135 are subject to UK customs duties at point of delivery. If your customer doesn't know this in advance, they either pay the unexpected charge (bad experience) or refuse delivery (a return you pay for). Display duty estimates at checkout, or use DDP (Delivered Duty Paid) shipping to absorb the uncertainty for them.

Attribution is completely different internationally

Your home-market ad account cannot run international ads efficiently. UK/US Meta CPMs commonly run several times higher than many home markets, audience sizes are smaller, and creative that works for your home market often fails with an international audience.

You need a dedicated international ad account, a market-specific pixel, and market-specific creative. The temptation is to just target "UK" from your existing home-market ad account — this works well enough to fool you into thinking it's fine, then quietly underperforms because the algorithm has no market-specific learning. See our guide to structuring a D2C ad account for the account-architecture principles that apply just as much across markets as across Meta and Google.

For one furniture brand we work with, setting up a dedicated UK Shopify store with a UK Meta Business Manager and UK-specific creative improved their UK ROAS from 1.2x to 2.4x within 90 days.

Fulfillment is what actually decides whether the market works

Everything above is solvable with configuration. Fulfillment is the part that determines whether the market is a real business or an expensive experiment, and it's where most international expansions quietly fail.

Cross-border shipping from your home market is the cheapest way to start and the hardest way to scale. Delivery times of 10–20 days are tolerable for a genuinely differentiated product and fatal for anything a customer could buy locally in two days. Returns are worse: a customer in another country returning an item internationally either costs you more in return shipping than the item's margin, or you eat the loss and write it off — and "we don't accept international returns" suppresses conversion more than most brands expect.

A local 3PL in-market fixes both but requires committing inventory to a market before you have demand data to justify it. The sequencing most brands land on: start cross-border with honest delivery-time messaging and a clear returns policy, treat the first 6–12 months as demand validation rather than optimization, and move to a local 3PL only once order volume in that market can absorb the fixed cost. Mejuri's international fulfillment build-out is a useful real-world reference for how that transition gets structured.

Localization past currency: payment methods and trust

Currency display is table stakes and often where brands stop. The details that actually affect conversion per market run deeper:

Payment methods are not universal. A checkout offering only card payments will underperform badly in markets where local methods dominate — iDEAL in the Netherlands, Klarna and other buy-now-pay-later options across much of Europe, cash on delivery in much of India and the Middle East. Shopify supports most of these, but they have to be deliberately enabled per market rather than assumed.

Sizing and units. UK versus US versus EU sizing, metric versus imperial dimensions — a size guide that only reflects your home market forces the customer to do conversion work, which is exactly the friction that produces both abandonment and returns.

Trust signals are local. A local-language contact option, a local returns address, and reviews from customers in that market do more for conversion than any amount of generic trust badging. A visitor deciding whether to buy from a foreign brand they've never heard of is mostly asking "what happens if this goes wrong," and the answer needs to be visible before checkout, not in a policy page.

FAQs

Should I use Shopify Markets or a separate store for international expansion? Markets is usually sufficient below a meaningful volume threshold in the new market; two fully separate stores make sense once you need different catalogues, marketing infrastructure, or operational SLAs per market.

How often should I review international pricing? Quarterly at minimum — FX rate movement of even a few percentage points compresses margins if your local-currency price stays fixed against a moving exchange rate.

Can I just target a new country from my existing home-market ad account? You can, but it consistently underperforms — the algorithm has no market-specific learning, CPMs and audience behavior differ meaningfully, and a dedicated account with market-specific creative outperforms every time we've tested it.

What's the biggest hidden cost in UK expansion specifically? Customs duties on orders over £135 post-Brexit — if the customer isn't shown this at checkout, they either refuse delivery (a return you absorb) or have a bad unboxing experience with an unexpected charge.

Should I set up a local 3PL before or after launching in a market? After, in most cases — start cross-border to validate demand, and commit inventory to an in-market 3PL once volume can absorb the fixed cost. Committing inventory before demand data exists is how expansions become expensive experiments.

What's the most overlooked localization detail? Payment methods — a card-only checkout underperforms badly in markets where iDEAL, Klarna, or cash on delivery are the norm, and these have to be deliberately enabled per market.

Our take

International expansion fails less often on strategy and more often on the unglamorous infrastructure underneath it — pricing cadence, duty transparency, and a genuinely separate ad account with its own learning. Get those three right and Shopify Markets or a second store both become viable; skip them and neither will save you. Mejuri's international fulfillment build-out is a real, sourced example of getting that infrastructure right rather than treating it as an afterthought.
