Best Payment Gateway for International Sales (2026)
Compare Stripe, PayPal, Adyen, Mollie and Wise on cross-border fees, currencies and local payment methods, with a worked $100 example.
The best payment gateway for international sales is Stripe for most small and mid-size online stores: it supports 135+ currencies, dozens of local payment methods, and clear pricing. PayPal works well as a second option for buyer trust. Adyen suits larger merchants. Your choice depends on where your buyers live and how much currency markups cost you.
Selling abroad looks simple until the first statement arrives. A 3.5% card fee, a 2% currency conversion charge and a 1% cross-border surcharge can quietly eat 6% of an order. This guide compares the main gateways, shows where the fees hide, and explains which local payment methods actually lift conversion.
What Makes the Best Payment Gateway for International Sales?
A good international gateway does four things: it displays prices in the buyer's currency, accepts the payment methods buyers trust locally, keeps conversion and cross-border fees low, and pays you out in a currency you can use. Miss any one and you lose either sales or margin.
Multi-currency checkout
A multi-currency gateway lets a buyer in Germany see euros and a buyer in Canada see Canadian dollars. Baymard Institute's checkout research consistently lists extra costs such as shipping, taxes and fees as the top reason shoppers abandon carts, and its surveys have put that figure at roughly half of all abandoners. A surprise currency conversion on a card statement belongs in the same bucket.
Local payment methods
Cards aren't the default everywhere. Local payment methods ecommerce shoppers expect include iDEAL in the Netherlands, Bancontact in Belgium, SEPA Direct Debit across the euro area, Klarna in Sweden and Germany, and Pix in Brazil. If you only offer cards, you're asking those buyers to pay your way instead of theirs.
Fee transparency
Look for three separate lines: the base processing rate, the currency conversion markup, and any cross-border or international card surcharge. Gateways that bundle them into one number often hide the worst one.
Cross Border Payment Fees: What You'll Actually Pay
Cross border payment fees typically add 1% to 4% on top of your standard rate. They come from three places: an international card surcharge, a currency conversion markup, and sometimes a fixed fee per payout or dispute.
Stripe international fees
According to Stripe's pricing page, US-based accounts pay 2.9% + 30¢ for domestic cards, plus an extra 1.5% for international cards, and another 1% when currency conversion is needed. A US store selling to a UK buyer in pounds can reach roughly 5.4% + 30¢. Rates vary by country, so check your own account's page.
PayPal currency conversion fee
The PayPal currency conversion fee is where many sellers get caught. PayPal's merchant fee page lists a currency conversion spread of roughly 3% to 4% above the base exchange rate depending on currency, a fixed fee per transaction, and an extra percentage on international payments. Exact figures change by country and account type, so treat the numbers here as a typical US-seller example. If you hold a balance in the buyer's currency and don't convert it, you avoid some of that spread.
A worked example
Say you sell a $100 item to a customer in France who pays in euros, from a US account. Using the typical rates above:
- Stripe: $2.90 + $0.30 base, $1.50 international card, $1.00 conversion = $5.70 (5.7%).
- PayPal: about 4.4% + $0.49 for an international standard checkout ($4.89), plus a 3.5% conversion spread ($3.50) = about $8.39 (8.4%). At a 3% spread it is $7.89; at 4% it is $8.89.
The gap is roughly $2.70 per $100 order. On 500 such orders a month at $100, that is about $1,350 in extra fees. Neither option is cheap, which is why presentment currency and local methods matter.
Payment Gateway Comparison: Stripe, PayPal, Adyen, Wise and More
Stripe, PayPal, Adyen, Mollie, Wise and Square all touch cross-border payments, but they differ sharply in reach and cost. The table below uses headline rates from each provider's own pricing page as we last checked them; confirm current pricing for your country before committing.
| Gateway | Best for | Currencies / reach | Typical pricing and watch-outs |
|---|---|---|---|
| Stripe | Small to mid-size stores | 135+ currencies, many local methods (per Stripe) | 2.9% + 30¢ US cards, +1.5% international, +1% conversion |
| PayPal | Buyer trust, second option | 200+ markets (per PayPal) | About 3-4% conversion spread plus international fee |
| Adyen | High-volume merchants | Global, with many local methods (per Adyen) | Interchange++ pricing plus a processing fee of about €0.11 per transaction; minimums apply |
| Mollie | EU small shops | Europe-focused, SEPA, iDEAL, Bancontact, Klarna | No monthly fee; per-transaction fees vary by method, with European cards from roughly 1.8% + €0.25 |
| Wise Business | Receiving and holding foreign funds | 40+ currencies held (per Wise) | Not a full checkout on its own |
| Square | Domestic-first sellers | Limited countries | Narrow international coverage |
Why Stripe wins for most stores
Stripe pairs automatic local currency display with wallets like Apple Pay and Google Pay, SEPA, iDEAL, Bancontact and Klarna, all under one integration. Its Adaptive Pricing feature shows buyers prices in their own currency and charges a conversion fee on top. It also supports Stripe Tax and Radar fraud screening. If you're comparing it with a competitor on payouts and fees, our Stripe vs Square breakdown shows the domestic side in detail.
Where PayPal still earns its place
Many buyers, especially in Germany, the UK and the US, trust the PayPal button and won't enter a card on an unfamiliar site. Offering it alongside Stripe usually raises conversion more than it raises cost. Our guide to adding PayPal to your online store walks through setup, and the Shopify Payments vs PayPal comparison covers payout holds.
When Adyen makes sense
Adyen supports a huge range of local methods and acquires directly in many regions, which can improve approval rates. Its interchange-plus model is cheaper at scale because you see the real card network cost, but the catch is that it's built for volume. If you process under roughly six figures a month, Stripe is easier and likely cheaper overall.
Where Wise and Square fit
Wise Business is not a checkout. It is a place to receive and hold money in local currencies, using bank details in regions such as the UK, EU, US and Australia, and then convert at the mid-market rate with a small disclosed fee. It suits freelancers and service sellers who invoice abroad, or product sellers who want to move payouts out of Stripe or PayPal cheaply. Square is strong at home but is available in only a handful of countries, so it rarely works as the main gateway for a store selling worldwide.
Example: a UK candle shop selling to the EU
Picture a hypothetical UK candle brand taking 300 orders a month at €40 from Germany, the Netherlands and France. By adding Stripe with iDEAL and SEPA alongside cards and PayPal, and pricing in euros with a euro balance, the shop avoids converting every payout. The bank-based methods usually cost less than cards, and paying European packaging suppliers from the same euro balance removes a second conversion. This is an illustration, not a client result, but the logic holds for any seller with costs in the buyer's currency.
Best Payment Gateway for an EU Online Store
For a payment gateway for EU online store sales, choose one that supports SEPA, strong customer authentication (3D Secure 2) and the local methods in your top markets. Stripe, Adyen, Mollie and PayPal all qualify; Mollie is a strong European-first pick for smaller shops because it has no monthly fee and simple per-method pricing.
Accepting euro payments as a small business
If you want to accept euro payments as a small business outside the eurozone, you have three options: price in euros and let your gateway convert at payout, open a euro balance (Stripe, Wise and PayPal all offer variants), or use a European entity. The balance route avoids repeated conversion charges if you also pay European suppliers in euros.
Rules you can't skip
- Strong customer authentication: Under the EU's PSD2 rules, most online card payments need two-factor checks. Good gateways handle this automatically, but it can lower conversion slightly.
- VAT: The EU's One Stop Shop scheme lets you file one return for sales to all member states. See the European Commission's taxation site for current thresholds.
- Price display: Show VAT-inclusive prices to EU consumers.
How to Accept Payments From Other Countries on Your Online Store
To accept payments from other countries online store owners should follow five steps: confirm your gateway supports your buyers' countries, enable presentment in local currencies, add two or three local payment methods, set shipping and tax rules, and test real checkouts from abroad.
- Check country coverage. Stripe and PayPal list supported business countries and buyer countries separately. Your business location limits what you can offer.
- Pick your top three markets. Look at your analytics, then add each market's most-used method rather than every method available.
- Turn on local currency pricing. Either let the gateway convert automatically or set manual prices per currency, which gives you cleaner psychological prices like €29 instead of €27.38.
- Handle duties and taxes. Decide whether buyers pay import duties on delivery or you collect them at checkout. Surprise customs bills cause refused parcels.
- Test from the buyer's side. Use a VPN or a friend abroad to confirm the checkout shows the right currency and methods.
Ways to cut cross-border fees
- Hold foreign balances instead of converting every payout.
- Prefer bank-based methods like SEPA or iDEAL, which usually cost less than cards.
- Negotiate custom rates once you pass about $80,000 a month in volume; Stripe and Adyen both offer them.
- Pay suppliers from the same foreign balance you earn in.
Platform fees matter too. On Shopify, using a gateway other than Shopify Payments adds a surcharge, covered in our third-party gateway fee guide. For wider context, see the best payment gateway for a small online store.
Which Gateway Should You Choose for International Sales?
Choose by situation, not by brand name. The right answer changes with your volume, your home country and where buyers live.
- Under $20,000/month, selling to the US and EU: Stripe plus PayPal.
- EU-based, mostly European buyers: Mollie or Stripe with SEPA, iDEAL and Bancontact.
- Over $100,000/month in many regions: Get quotes from Adyen and Stripe, then negotiate.
- Mostly receiving funds as a service seller: Wise Business with a checkout tool on top.
One more check: avoid gateways that lock you into one platform's checkout. Chargebacks are also more frequent on international orders, so read our guide on how to handle chargebacks before you scale abroad.
Common questions
Is Stripe or PayPal cheaper for international sales? Stripe usually is, mainly because its conversion markup is about 1% versus PayPal's 3% to 4% spread. PayPal often converts better on trust.
Can I accept payments in multiple currencies with one account? Yes. Stripe, PayPal and Adyen all let you present prices in many currencies from a single account.
Do I need a foreign bank account? Not usually. Local-currency balances through Stripe, PayPal or Wise often remove that need.
Conclusion: Build Your Store Around Global Checkout
The best payment gateway for international sales is the one that matches your buyers: Stripe as the core, PayPal as the trust layer, and local methods in your top two or three markets. Do the fee math on a real $100 order before you commit, because the gap between 3% and 6% is your margin.
