SHOPLINE Fees Calculator: What Each Gateway Really Costs

There's no single number, because there's no single gateway

If you're looking for a shopline fees calculator that spits out one flat percentage, the honest answer is that it doesn't exist, because SHOPLINE doesn't run on one flat fee. Every payment method you switch on, FPS, cards, Alipay HK, ECPay, PayNow, has its own rate, and your real cost is the weighted blend of whatever your customers actually choose. This is a gateway-by-gateway breakdown of what those rates actually are, market by market, so you can build that blend yourself.

Hong Kong: the wallet methods are the cheap ones

Through SHOPLINE Payments in Hong Kong, the local wallet and bank-transfer methods run noticeably cheaper than cards:

• FPS (Faster Payment System): around 1.5%
• WeChat Pay: around 1.5%
• Alipay HK: around 1.9%
• Card rates (Visa, Mastercard, AMEX, JCB, Diners, UnionPay): higher than the local wallet methods

The methods a lot of HK stores skip, mainly FPS, are the ones actually worth turning on for cost reasons as well as conversion reasons: it's fast, shoppers trust it, and at roughly 1.5% it's meaningfully cheaper than routing the same transaction through a card. If you need a payment option SHOPLINE Payments doesn't cover, Stripe is available as a third-party gateway for HKD stores, at Stripe's own published rates rather than SHOPLINE Payments' rates.

Taiwan: ECPay, and a fee rule that changes who pays

Taiwan runs primarily through ECPay, and the methods Taiwanese shoppers actually use are not card-first: credit card, convenience-store payment by barcode or code, ATM and virtual-account transfer, and web-ATM, layered with LINE Pay and JKOPay.

The rule that actually matters for your margin math in Taiwan: SHOPLINE lets you pass the payment processing fee to the customer as a surcharge in most markets, but Taiwan is the explicit exception. The regulator there prohibits surcharging on one-time credit-card payments, so that processing cost stays on your side of the ledger in Taiwan even if you've built your pricing model around passing it through elsewhere. If you sell into multiple APAC markets with a single blended-margin assumption, this asymmetry alone can be the gap between your model and your actual take-home.

Singapore: card-comfortable, but leaving money on the table without the local methods

Singapore is the most card-friendly of the three markets, with SHOPLINE Payments covering cards plus multi-currency checkout for cross-border buyers. But card-only still costs you conversions and, in some cases, margin:

• PayNow: the near-universal local bank-transfer method
• GrabPay: rides on an app most Singaporean shoppers already have open
• Atome: buy-now-pay-later, covers the instalment-preferring shopper

Some of these arrive natively depending on your plan, others come through an add-on; confirm what's built in for your specific plan rather than assuming coverage.

Find your own current mix before you model anything

None of the percentages above matter until you know which methods your customers are actually choosing today. Before modeling a blended rate, pull your payment-method breakdown from SHOPLINE's reporting: if the bulk of your Hong Kong volume is already running through cards rather than FPS, your real blended rate is going to sit closer to the card rate than the wallet rate, no matter how attractive the wallet numbers look on paper. The gateway-by-gateway numbers above are the inputs; your actual method mix, by market, is the weight each input gets in your real blended cost.

BNPL: real conversion lift, real fee premium

Atome is available across Hong Kong, Singapore, Malaysia, and Taiwan, typically structured as three interest-free instalments for the shopper. It measurably lifts conversion and average order value, especially on higher-ticket items, and APAC shoppers increasingly expect it as an option. The tradeoff: the merchant-side BNPL fee sits above a normal card rate. That's a fine trade when a larger order absorbs it. It's a quiet margin leak when it gets bolted onto low-ticket, already-thin-margin items where the fee eats a disproportionate share of what's left.

Building your actual blended rate

Add it up and the real question isn't "what does SHOPLINE charge," it's "what does my specific mix of methods, markets, and order sizes actually cost me." A store that's 70% FPS/WeChat in Hong Kong has a fundamentally different blended rate than one that's 60% ECPay-card in Taiwan, even on the exact same product line.

Gateway fees also don't operate in isolation from the rest of your checkout economics. A high-fee method like BNPL stacked on top of a discount code, the kind covered in SHOPLINE discount stacking, compounds faster than either cost does on its own: the discount reduces revenue, the gateway fee takes its cut of what's left, and on a low-ticket order the two together can turn a break-even sale into a loss. Modeling gateway fees and discount stacking separately, which most merchants do, misses exactly this kind of compounding.

Two ways to get a concrete number instead of a vague sense of it:

• Run a representative order through the gross profit per order calculator to see what actually survives after gateway fees, discounts, and shipping stack on top of your product cost.
• If you sell the same SKU across Hong Kong, Taiwan, and Singapore, the multi-currency margin calculator shows what the same item actually nets you in each market once local gateway fees and FX are both accounted for, which is usually a bigger spread than merchants expect.

For the full picture beyond just gateway fees, including subscription tiers, BNPL, and the app-based costs that add up quietly, see the real cost of selling on Shopline. And if your actual risk is that a stacked discount plus a high-fee gateway pushes a specific order below cost at the moment it's placed rather than a week later in a report, that's the gap Agentis closes: it evaluates the full order, discount, shipping, gateway fee, and FX included, and flags or fixes the ones that lose money before they ship.

Frequently Asked Questions

What's the cheapest payment method to accept on SHOPLINE in Hong Kong?

FPS and WeChat Pay both run around 1.5%, noticeably cheaper than card rates through SHOPLINE Payments. Alipay HK runs around 1.9%. If cost is the priority and your customers are comfortable with wallet or bank-transfer methods, steering volume toward FPS is the cheapest lever available.

Can I pass the card processing fee to the customer in Taiwan?

No. Taiwan's regulator prohibits surcharging on one-time credit-card payments, which is an exception to SHOPLINE's general ability to pass payment fees through to the customer in most markets. In Taiwan, that processing cost stays on the merchant side.

Is Atome worth the higher BNPL fee on SHOPLINE?

It depends on order size. Atome's merchant fee runs above a standard card rate, but it also lifts conversion and average order value, particularly on higher-ticket items. The trade tends to work in your favor on items where the fee is a small fraction of the order and works against you on low-ticket items where the fee eats a large share of an already-thin margin.

Is there a single flat SHOPLINE processing fee I can budget for?

No. SHOPLINE supports multiple payment methods per market (FPS, cards, Alipay HK, and WeChat Pay in Hong Kong; ECPay-routed cards, convenience-store, ATM, LINE Pay, and JKOPay in Taiwan; cards, PayNow, GrabPay, and Atome in Singapore), each with its own rate. Your real cost is the weighted average across whichever methods your customers actually choose, which varies by market and by how you configure your checkout.
