For an e-commerce business, the payment provider is not just a checkout button. Stripe, Adyen or Mollie affect accounting reconciliation, fees, refunds, disputes, currencies, VAT and margin by channel.
The right choice depends on the model: French Shopify store, European DNVB, marketplace, subscription SaaS, omnichannel retail or international group.
Executive summary#
- Stripe is often strong for startups, SaaS, subscriptions and fast integrations.
- Adyen is usually considered for larger volumes, omnichannel flows and international operations.
- Mollie can be a pragmatic option for European merchants seeking accessible deployment.
- The accounting criterion is the ability to reconcile sales, fees, refunds, disputes, currencies and VAT.
Operational comparison#
| Criterion | Stripe | Adyen | Mollie | Hayot Expertise view |
|---|---|---|---|---|
| Natural fit | Startup, SaaS, agile e-commerce | Retail, scale-up, high volumes | European SME merchant | Match PSP to finance maturity |
| Integrations | Very broad ecosystem | Powerful but structured project | Fast for SMEs | Check Shopify, ERP, accounting and bank |
| Reconciliation | Rich exports to configure | Robust if setup is clean | Simple but needs testing | Write the reconciliation plan |
| International | Strong | Very strong | Europe-friendly | Currencies and local methods affect accounting |
| Risk | Fees and refunds complexity | Heavier integration project | Limits for advanced models | Net margin by channel matters more than headline rates |
Use cases and decision points#
- A B2B SaaS with subscriptions may prefer Stripe if monthly reconciliation is properly designed.
- An omnichannel retailer with international flows may prefer Adyen with a structured implementation.
- A growing European store may find Mollie practical if accounting exports are sufficient.
- Marketplace and cross-border flows require testing VAT, fees, refunds, credit notes and cut-off before choosing.
Our accountant's analysis#
We never stop at the commission rate. We review net settlement: gross sales, PSP fees, refunds, chargebacks, currencies, marketplace commissions, VAT and timing between order, payment and shipment.
A PSP can be excellent commercially but weak for accounting if exports do not rebuild margin by channel.
For a CFO or founder, the best test is a reconciliation file built from real data: order platform, PSP, bank, invoices, credit notes and VAT. If that file cannot be produced reliably, the apparent payment solution will create finance debt.
The underestimated risk#
The underestimated risk is the gap between platform revenue and accounting revenue. Refunds, fees, taxes, commissions and settlement delays can create material differences.
French e-invoicing and e-reporting also require better flow qualification. The PSP does not decide VAT treatment alone.
What the CEO must decide#
- Is your priority conversion, international coverage, omnichannel setup or reconciliation quality?
- Who reconciles payments each month and at what level of detail?
- Are sales B2B, B2C, France, EU, non-EU, marketplace or subscription-based?
- Which exports will be provided to the accountant and in what format?
2026 watchpoints#
- Test a real month with sales, refunds, disputes and fees before full migration.
- Document accounting treatment: gross sales, PSP fees, VAT, receivables, bank, FX differences.
- Check local payment methods outside France.
- Reconcile PSP data with Shopify, Amazon, ERP, bank and accounting software.
