A UK business sells a £100 product to an EU customer via PayPal. PayPal shows: 3.4% fee = £3.40. But also charges: £0.20 per transaction, 2% currency conversion. True cost: £3.40 + £0.20 + £2 = £5.60 (5.6% of sale). On £100K annual EU sales, that's £5,600 in hidden PayPal fees. Post-Brexit, this is unavoidable, but you can optimize.

The Hidden PayPal Cross-Border Cost#
Pre-Brexit, UK businesses sold to EU with minimal friction. Post-Brexit, payment processors charge "cross-border" fees on top of standard rates. PayPal: 3.4% + £0.20 per transaction (standard) + 2% for currency conversion. A £100 UK sale to an EU customer in EUR: (1) PayPal fee: 3.4% = £3.40. (2) Transaction fee: £0.20. (3) Currency conversion: 2% (£100 GBP → €118 EUR, actual rate 1.17, PayPal rate 1.15 = 1.7% loss). Total cost: £5.60 (5.6%). Compare to domestic UK sale: 3.4% + £0.20 = £3.60 (3.6%). EU sales cost 2% more just from fees. On £500K annual EU sales, that's £10K in additional fees.
Why EU Customers Cost More Post-Brexit#
UK is now "third country" for EU VAT purposes. This adds friction and cost. Customers might need to pay VAT upfront (increases price, reduces conversion). Businesses might need customs forms (delays, complexity). Stripe and Square don't charge cross-border fees, but PayPal does. This shifts the incentive toward Stripe for EU sales.
AskBiz Payment Processor Comparison by Market#
AskBiz tracks: (1) Revenue by customer geography. (2) Payment method by geography. (3) Fees charged by PayPal, Stripe, Square for each region. Report shows: "UK domestic (Stripe): 2.9% + £0.30 = 3.2% cost. EU sales (PayPal): 5.6% cost. US sales (Stripe): 3.2% cost. Recommendation: Switch EU customers from PayPal to Stripe (saves 2.4% on EU sales)."
Real Example: UK Ecommerce Store#
A UK clothing store had 30% of sales from EU customers, 70% from UK customers. They used PayPal for all (consistency). EU fees averaged 5.6%, UK fees 3.2%. Blended average cost: (0.3 × 5.6%) + (0.7 × 3.2%) = 3.92%. After analyzing with AskBiz: (1) Switched EU customers to Stripe (3.4% cost for EU cross-border with Stripe, still cheaper than PayPal). (2) Kept PayPal for UK (competitive with Stripe). (3) New blended cost: (0.3 × 3.4%) + (0.7 × 2.9%) = 3.07%. Savings: 0.85% on revenue. On £500K annual sales, that's £4,250/year saved.
How the Currency Conversion Margin Actually Works#
The most invisible part of a cross-border PayPal transaction is not the headline processing fee — it is the exchange rate applied to convert the customer's euros into pounds landing in the seller's account. PayPal, like most payment processors, does not use the mid-market exchange rate — the real, interbank rate you would see quoted on a financial news site at any given moment — when converting a payment. Instead it applies that mid-market rate minus its own margin, typically several percentage points, and the seller receives the converted amount without ever seeing the mid-market rate the conversion was actually measured against. A Brighton homeware seller processing roughly €3,000 a month in EU sales through PayPal decided to check this directly: she noted the exact time a €120 order was paid, looked up the mid-market EUR/GBP rate at that timestamp from a currency data site, and compared it to the GBP amount that actually landed in her PayPal balance once the conversion had been applied. The gap was just over 4% — meaning on that single order alone, PayPal's conversion margin had cost her close to £4 that never appeared as a labelled fee anywhere in her transaction history. Multiplied across a full month of EU sales, that hidden margin was costing her more than her explicit, visible cross-border transaction fees combined. The practical exercise any seller can run is straightforward: pick a handful of recent EU transactions, note the payment timestamp, look up the mid-market rate at that moment, and compare it to what actually landed after conversion. The percentage gap is the seller's real, all-in currency conversion cost — a number that does not appear on any PayPal fee summary because it is baked into the exchange rate itself rather than itemised as a separate charge. Sellers who do this exercise are often surprised that the conversion margin, not the advertised cross-border fee, is the larger cost.
Holding a EUR Balance: A Way to Avoid Repeated Conversion#
For a UK seller with genuinely recurring EU revenue, one practical way to reduce the drag of repeated currency conversion is to stop converting every single transaction and instead hold a EUR balance through a multi-currency business account, converting to GBP only periodically and on the seller's own terms. Several UK business banking and payments providers now offer accounts that can hold multiple currencies natively, meaning EU customer payments can be received and simply sit in a EUR balance rather than being automatically converted to GBP the moment they arrive. This matters for two reasons. First, it removes the per-transaction conversion margin that would otherwise be charged on every single EU sale — instead, the seller converts in larger batches, at a time of their choosing, and can shop around for the best available conversion rate at that moment rather than accepting whatever rate the payment processor applies automatically and invisibly. Second, it gives the seller flexibility to pay EUR-denominated costs — a European supplier invoice, EU marketplace fees, or EU-based advertising spend — directly out of the EUR balance without converting to GBP and back to EUR again, avoiding a double conversion cost entirely. A Cambridge stationery brand selling steadily into Germany and France, with monthly EU revenue in the region of €8,000-€10,000, moved from receiving all EU payments directly into PayPal (with automatic conversion on every transaction) to routing EU marketplace payouts into a EUR-holding business account, converting in a single monthly batch. The batched conversion, done through a provider offering a rate close to mid-market rather than PayPal's built-in margin, meaningfully reduced their effective conversion cost compared to converting every transaction individually. This approach is not worthwhile for a seller doing occasional, small EU sales — the administrative overhead of managing a second currency account outweighs the saving at low volume — but for a business with steady, material EU revenue, it is one of the more effective structural fixes available, because it addresses the exchange rate margin directly rather than just shopping for a marginally better processor.
When Fee Optimisation Is and Isn't Worth the Effort#
Not every UK seller should spend time chasing a cheaper cross-border payment setup, and knowing where that line sits saves wasted effort. A business making a handful of EU sales a month — say, under £500 in total EU revenue — is very unlikely to see a return on the time spent evaluating alternative processors, setting up a multi-currency account, or renegotiating payment terms, because the pounds saved on a few percentage points of fee difference are small in absolute terms, while the administrative overhead of managing an additional account or provider relationship is roughly fixed regardless of volume. For that seller, the cross-border fee is simply a modest cost of doing occasional EU business, not a problem worth solving. The calculation flips once EU sales become a material and recurring part of revenue. A business processing £2,000 or more in EU sales every month is very plausibly losing several hundred pounds a year to conversion margin and cross-border fees combined, at which point the time spent setting up a better processor or a multi-currency account pays for itself many times over, often within the first month or two. The genuine difficulty most UK SMBs face is not deciding whether optimisation is worth it in principle — it is that they simply do not know their real EU sales volume and true blended fee cost, because PayPal's transaction history buries the conversion margin inside the settled amount rather than reporting it as a clearly labelled line item, so most owners are optimising from a guess rather than a number. AskBiz's per-transaction fee tracking closes exactly that gap: it logs the payment processor, the fee charged, and the effective conversion cost against a reference exchange rate for every order, so a seller can see, over any given month or quarter, precisely how much EU revenue they are processing and precisely what it is costing them in total — the two numbers needed to make this decision on evidence rather than instinct. For a seller sitting near the threshold where optimisation starts to matter, that visibility alone is often what turns a vague sense that "PayPal fees feel high" into a concrete, defensible decision to switch, batch conversions, or simply leave things as they are because the volume genuinely does not justify the change.

Which processor is cheapest for EU sales from UK?
Stripe: 3.4% + £0.20 per transaction. Wise (formerly TransferWise): 1.5% + £0.35 per transaction. Wise is cheapest for high volume.
Should I invoice in GBP or EUR?
GBP shifts currency risk to customer. EUR shifts it to you. PayPal and Stripe charge 1-2% for conversion either way. EUR invoicing might increase conversion (customer sees familiar currency).
Can I avoid cross-border fees?
Only by operating in EU (have EU bank account, sell from EU). Most UK businesses accept the fees and price accordingly.
