On a French e-commerce site of EUR1M revenue, PSP fees average EUR18,000-28,000 per year. This expense, often considered incompressible, can be cut by 25-40% through informed PSP choice, rigorous accounting method (512x gateway accounts) and a few negotiable optimisations.
Cabinet Hayot Expertise in Paris breaks down for you the real costs of Stripe, PayPal, Mollie and Klarna in 2026, with a quantified client case and our reproducible 512x method.
Hook: 1.4% + EUR0.25 on Stripe — but really how much?#
The displayed Stripe rate (1.4% + EUR0.25 on EU cards) covers only the simplest part. Add to it:
- Premium card surcharges (Amex, business cards): +0.5 to +1.5%
- Non-EEA card surcharges: +1 to +2%
- Dispute fees (chargebacks): EUR15 per dispute even won
- Currency conversion: +1% spread
- International payout (to non-FR bank): +1%
On a EUR50 AOV with typical mix (60% standard EU cards, 25% premium cards, 10% non-EEA cards, 5% chargebacks/disputes), real Stripe cost is ~2.1% on average — not 1.4%.

| PayPal Business FR | 2.9% + EUR0.35 (intl 1.2-3.4%) | varies per country | EUR0 | 35% of FR buyers have a PayPal account, conversion lift |
| Mollie | 1.2% + EUR0.25 (EU cards) | 1.8% + EUR0.25 | EUR0 | EU local payments (iDEAL Netherlands, Bancontact Belgium), 15-25% cheaper than Stripe in Europe |
| Klarna BNPL (general) | 3.29% to 5.99% + USD0.30 per transaction | n/a (EU only) | EUR0 | High-volume merchants (>USD5M revenue) negotiate to 3.29%; +20-40% basket, +10-30% conversion |

Real cost calculation per profile#
Profile 1 — Fashion DTC AOV EUR50, EUR50k revenue/month#
- 100% Stripe: 50,000 × 2.1% + 1,000 × EUR0.25 = EUR1,300/month
- 70% Stripe + 30% PayPal: EUR1,415/month
- 70% Stripe + 20% PayPal + 10% Klarna: EUR1,480/month but with +15% conversion = +EUR6,750/month additional revenue ⇒ very positive ROI
Profile 2 — Marketplace AOV EUR15, EUR30k revenue/month#
- 100% Stripe: 30,000 × 2.3% + 2,000 × EUR0.25 = EUR1,190/month
- On small baskets, the EUR0.25 fixed fee weighs heavily: Stripe Volume Tier (reduction of fixed fee to EUR0.15 above EUR250k/month) becomes critical
Profile 3 — International dropshipping AOV EUR25, EUR80k revenue/month#
- 70% Stripe + 30% PayPal + Wise for CN suppliers: ~EUR2,100/month payment fees
- Possible savings with Mollie for multi-country EU sales: -8 to -12%
The Cabinet Hayot Expertise 512x method — dedicated gateway accounts#
Without dedicated 512x account per PSP, your bank reconciliation is wrong: the received transfer aggregates gross revenue, commissions, refunds, chargebacks and dispute fees. Cabinet Hayot Expertise structures:
| Account | PSP |
|---|---|
| 512100 | Stripe gateway |
| 512110 | PayPal gateway |
| 512120 | Klarna gateway |
| 512130 | Shopify Payments gateway |
| 512140 | Alma gateway |
| 512150 | Mollie gateway |
Combined with 627 sub-accounts (PSP fees per type), this breakdown makes bank reconciliation instant and net margin reliable.

Frequently asked questions
Stripe ou PayPal : lequel coûte le moins cher en 2026 ?
Stripe : 1,4 % + 0,25 € par transaction zone EEE (cartes UE). PayPal : 2,9 % + 0,35 € en moyenne par transaction. Sur un panier moyen de 50 €, Stripe coûte 0,95 € contre 1,80 € pour PayPal — soit 47 % moins cher.

Mollie est-il vraiment compétitif vs Stripe pour un e-commerce français ?
Mollie est en réalité moins cher que Stripe sur les cartes EU : 1,2 % + 0,25 € (Mollie, source mollie.com/fr/pricing) contre 1,4 % + 0,25 € (Stripe). Mollie est particulièrement compétitif sur les e-commerces vendant en multi-pays UE grâce à ses moyens de paiement locaux (iDEAL Pays-Bas, Bancontact Belgique, SOFORT Allemagne). Pour un e-commerce purement FR sur cartes uniquement, l'écart est faible. Pour un e-commerce multi-pays UE, Mollie peut booster la conversion de 8-15 % et coûter 15-25 % moins cher en frais.

Klarna applique des frais variables selon le pays, le moyen de paiement (Pay Now, Pay in 4, Pay in 30, Financing) et le volume marchand : grille indicative 3,29 % à 5,99 % + 0,30 USD par transaction (sources Klarna.com et chargeflow.io 2026). Les marchands à fort volume (> 5 M USD CA annuel) négocient typiquement à 3,29 %. Sur un panier 100 €, le coût Klarna varie de 3,59 € à 6,29 € selon votre profil. À comparer au lift de conversion (10-30 %) et à l'augmentation du panier moyen (20-40 %) : Cabinet Hayot Expertise calcule le ROI Klarna par client, généralement positif au-dessus de 60 € de panier moyen.
