Shopify's plan fee is just the start. UK merchants pay additional charges through third-party gateway fees, currency conversion, app subscriptions, chargeback costs, and payout delays — most of which aren't clearly flagged. Here's what you're actually paying.

The Shopify fee you see is not the Shopify fee you pay

Shopify's pricing page shows plan costs and standard card processing rates clearly enough. What it doesn't lead with is the full picture of what UK merchants pay once the store is live — the transaction fees on third-party gateways, the currency conversion markups, the chargeback costs, the cumulative app subscriptions, and the cash flow cost of payout delays.

None of these charges are hidden in the sense of being deliberately concealed. They're all disclosed somewhere in Shopify's documentation. But they're not always prominent when merchants are evaluating what a Shopify store will cost to run, and they tend to be discovered gradually as the store scales — often after revenue is already committed to a cost structure that's harder to change.

This guide covers the most significant additional charges UK Shopify merchants encounter beyond the plan fee, what they actually cost, and where switching to Pay by Bank via Fena reduces or eliminates specific fee categories.

Note on fee accuracy:

Shopify fee structures can change. The figures in this guide reflect publicly available Shopify pricing as of early 2025. For the most current information, Shopify's pricing pages and Shopify support are the authoritative sources.

Quick summary

• Shopify charges an additional transaction fee of 0.5–2% per order on top of gateway fees when merchants use any payment method other than Shopify Payments — this applies to PayPal, Klarna, and all other third-party gateways

• International sales attract a currency conversion fee through Shopify Payments, and non-UK card surcharges that add further cost on cross-border transactions

• Shopify's app ecosystem is almost always necessary for a fully functional store, but app subscription costs compound significantly at scale and aren't always in the initial cost model

• Chargeback fees — charged per dispute regardless of outcome — add a hidden per-transaction risk cost on card and PayPal payments

• Payout delays of 3–5 days on Shopify Payments and potentially much longer with PayPal create a working capital cost that doesn't appear as a line item but affects cash flow in real terms

• Pay by Bank via Fena addresses several of these: it doesn't trigger Shopify's third-party gateway fee, has no chargebacks, and settles same-day rather than in 3–5 days

The third-party gateway fee most merchants miss

This is the charge that surprises the most UK Shopify merchants. If you use any payment method other than Shopify Payments — PayPal, Klarna, Stripe directly, a specialist high-risk processor, or any other third-party gateway — Shopify charges an additional transaction fee on every order.

The fee varies by plan: 2% on the Basic plan, 1% on the Shopify plan, and 0.5% on Advanced. It's applied to gross revenue and deducted before you receive your payout. It's charged in addition to whatever the payment provider itself charges — so a merchant on the Basic plan using PayPal is paying PayPal's own processing fee plus a 2% Shopify surcharge on every transaction.

The commercial impact depends on volume and plan, but it's meaningful at scale. A merchant on the Shopify plan doing £500,000 annually in revenue through PayPal pays £5,000 to Shopify in gateway surcharges, on top of PayPal's own fees. These two costs together frequently make third-party gateways significantly more expensive than they appear from their own pricing.

Pay by Bank via Fena is connected to Shopify through the payment gateway integration in a way that avoids triggering the Shopify third-party transaction fee for merchants who meet Shopify's eligibility requirements. This makes the effective cost of Pay by Bank lower than many merchants initially estimate when comparing gateway rates in isolation.

Currency conversion and international sales

UK merchants who sell internationally — or who attract a proportion of non-UK traffic — encounter additional charges that don't appear in domestic processing rates.

Shopify Payments charges a currency conversion fee on cross-currency transactions. On a £100 equivalent order from a US customer, a 2% conversion fee means £2 is lost before the transaction cost is applied. For merchants running international paid advertising or shipping internationally as a meaningful part of revenue, this adds up.

Non-UK card surcharges compound this further. Interchange rates for non-UK issued cards are typically higher than for UK domestic cards, and some card types carry surcharges of 2–3.25% or more that get passed through in processing rates. A merchant who has negotiated or assumed a particular effective processing rate based on their domestic card mix may find that international card volume drives the actual effective rate meaningfully higher.

The most straightforward way to reduce international payment cost exposure is to prioritise payment methods that don't have currency conversion markup — which for UK-to-UK transactions means Pay by Bank, since it settles in GBP between UK bank accounts with no conversion step.

App subscription costs: the compounding overhead

Shopify's base functionality covers order management, checkout, and basic analytics. Most merchants running anything beyond a minimal store use apps for email marketing, product reviews, loyalty programmes, upsell and cross-sell tools, advanced analytics, inventory management, and similar functions. Almost none of these are included in the plan fee.

App costs range widely — from under £10 per month for simple tools to several hundred pounds per month for high-volume automation platforms, with some apps charging a percentage of revenue generated or managed rather than a flat fee. The per-app cost looks manageable in isolation. Across five to ten apps — which is typical for a fully operational Shopify store — the monthly total becomes a significant overhead that scales less predictably with the business than the plan fee does.

The compounding problem is that apps are easy to add and easy to forget. An app installed to solve a specific problem during a busy period and never removed continues to bill monthly. An app that was cost-effective at £2,000 monthly revenue may be disproportionately expensive at £200,000 monthly revenue if it charges as a percentage. Regular audits of the app stack — checking what's installed, what's actively used, and whether the cost justifies the value at current revenue — are a practical cost control measure that many merchants don't do systematically.

Chargeback costs: the per-dispute fee most merchants don't budget for

Every card payment dispute that becomes a formal chargeback carries a fee — typically £10–£25 per case in the UK — charged by the acquirer or gateway, regardless of whether the merchant wins or loses the dispute. For most merchants with low chargeback rates, this is a manageable background cost. For merchants in categories with higher dispute rates — digital goods, high-value orders, regulated products — it can be a meaningful per-transaction risk cost.

Chargebacks also carry indirect costs: the staff time to compile evidence, respond within deadlines, and manage the administrative workflow of dispute handling. And beyond individual costs, a rising chargeback ratio triggers consequences from payment processors — higher processing fees, rolling reserves, or in serious cases account termination.

Pay by Bank via Fena doesn't carry chargeback exposure. Because the payment goes through open banking rails rather than card networks, the card chargeback mechanism doesn't apply. There are no chargeback fees, no dispute response timelines, and no impact on a dispute ratio. For merchants where chargebacks are a recurring cost — whether from genuine fraud, friendly fraud, or the categories that attract elevated dispute rates — removing this cost category on Pay by Bank volume has a real margin impact.

Payout delays: the working capital cost no one talks about

Shopify Payments releases funds to merchants in 3–5 business days. PayPal's timeline is more variable — established merchants typically see 3–5 days, but new accounts and those flagged for review can face holds of 7–21 days or longer. Klarna's settlement windows for instalment products are even longer.

These delays don't appear as a fee on any invoice. But they have a real working capital cost. Revenue earned on Tuesday isn't available until the following week. For merchants who need to restock inventory, pay fulfilment partners, or fund marketing spend against incoming revenue, this creates a gap that either requires a credit facility to bridge or constrains what can be done in the meantime. The cost of that credit facility — or the opportunity cost of the constrained operations — is a real cost of the slow settlement cycle.

Pay by Bank via Fena settles same-day or faster. The payment confirms and the funds arrive in the merchant's bank account the same day, rather than 3–5 days later. For merchants managing cash flow actively — particularly those with thin working capital margins or high-velocity inventory requirements — the timing improvement has practical operational value beyond just preferring faster money.

Theme and design costs: the one-time charges that add up

Shopify's free themes are functional but limited in features and performance optimisation. Most merchants selling seriously upgrade to paid themes, which typically cost £140–£300 as a one-time purchase. Some premium theme developers also sell add-on functionality or charge for version updates.

Beyond the theme itself, merchants often purchase or subscribe to specific design or performance tools — page builders, speed optimisation tools, A/B testing platforms — that add to the initial setup cost and sometimes to ongoing subscriptions.

These costs are genuine but often one-time rather than recurring, and they scale less directly with revenue than gateway and app costs. They're worth budgeting for accurately upfront rather than discovering them as unexpected expenses during the launch phase.

The realistic cost of a UK Shopify order at different payment methods

To make the comparison concrete, consider a £200 order through different payment methods for a merchant on the Shopify plan (1% third-party gateway fee where applicable):

Shopify Payments / standard card:

approximately 1.9% plus £0.25, with no additional Shopify gateway surcharge. Total cost approximately £4.05.

PayPal:

PayPal's own fee (approximately 3.4% plus £0.20 at standard rates) plus the 1% Shopify surcharge. Total approximately £9.20.

Klarna Pay in 3:

Klarna's fee (approximately 5.99% plus £0.20) plus the 1% Shopify surcharge. Total approximately £14.18.

Pay by Bank via Fena:

Fena's processing fee (approximately 0.5–1% depending on volume) with no Shopify gateway surcharge for eligible merchants. Total approximately £1.20–£2.25.

The comparison illustrates why payment method choice has a disproportionate impact on effective margin compared to plan choice. Moving from PayPal to Pay by Bank on a £200 order saves approximately £7 per transaction. Across meaningful volume, this compounds quickly.

Practical steps for reducing your Shopify cost base

Audit your payment method mix.

Understand what proportion of your volume goes through each payment method and calculate the effective fee rate for each. If a significant proportion of volume is on PayPal or Klarna, the gateway surcharge plus their own fees may be materially higher than you realise.

Add Pay by Bank via Fena.

This is the most direct fee reduction available for most UK merchants. It lowers processing cost, eliminates chargeback exposure on Pay by Bank volume, and settles faster. Adding it doesn't require removing other payment methods — it gives customers an additional option and allows volume to shift naturally.

Review your app stack quarterly.

Remove apps you're not actively using. Check whether any percentage-of-revenue apps have become disproportionately expensive at your current scale. Look for cases where Shopify's native functionality has expanded to cover what you're paying a third-party app to do.

Understand international fee exposure.

If you're driving international traffic through paid advertising, model the currency conversion and non-UK card surcharge impact on your effective margin. Consider whether domestic GBP checkouts and Pay by Bank for UK customers reduce your exposure.

Budget correctly for one-time costs.

Theme and initial design costs are predictable. Make sure they're in your launch budget rather than being discovered post-launch.

Frequently asked questions

What are the main hidden fees UK Shopify merchants pay?

The most significant additional charges beyond the plan fee are: the third-party gateway surcharge (0.5–2% per order if not using Shopify Payments), currency conversion fees on international sales, app subscription costs, chargeback fees per dispute, and the working capital cost of 3–5 day payout delays.

Does the Shopify third-party gateway fee apply to Pay by Bank?

Pay by Bank via Fena integrates with Shopify in a way that may avoid triggering the third-party gateway surcharge for eligible merchants. This makes the effective cost of Pay by Bank lower than many comparisons suggest. Confirm eligibility with Fena during the integration discussion.

Why does using PayPal on Shopify cost more than it appears?

PayPal's own processing fee (approximately 3.4% plus £0.20 at standard UK rates) applies alongside Shopify's third-party gateway surcharge of 0.5–2% depending on your plan. The two fees together make PayPal one of the more expensive payment method combinations for Shopify merchants.

How do chargebacks add to Shopify processing costs?

Each card or PayPal dispute that becomes a formal chargeback carries a fee of typically £10–£25, charged regardless of whether the merchant wins. Beyond the fee, chargebacks cost internal handling time and, at elevated rates, trigger higher processing costs or account restrictions from card processors.

Does Pay by Bank via Fena have chargebacks?

No. Pay by Bank transactions don't go through card networks, so the card chargeback mechanism doesn't apply. There are no chargeback fees and no dispute ratio implications on Pay by Bank volume.

How does Pay by Bank settlement compare to Shopify Payments?

Shopify Payments releases funds in 3–5 business days. Pay by Bank via Fena settles same-day or faster. For merchants managing working capital against incoming revenue, the timing difference has practical operational value.

What's the most effective way to reduce hidden Shopify fees?

For most UK Shopify merchants, adding Pay by Bank via Fena produces the largest single reduction in effective payment costs — eliminating the gateway surcharge (where applicable), reducing processing fees, removing chargeback exposure, and improving settlement timing. Quarterly app stack audits and monitoring of international fee exposure are the next most impactful ongoing practices.
