Short answer. The Prestashop / Shopify choice is not only about design or SEO. From a French CPA's perspective, it impacts OSS/IOSS VAT, 2026 e-invoicing, PSP reconciliation and total annual cost. Shopify wins on speed and EU VAT setup reliability. Prestashop keeps a lead on code-level control, custom modules and self-hosting. This comparison lists the criteria that actually flip the decision in 2026.
1. The forgotten #1 criterion: 2026 e-invoicing#
From 1 September 2026, all French companies must receive structured e-invoices (Factur-X, UBL, CII) through a PDP. B2B issuance follows progressively.
- Shopify: plug-in via Pennylane (candidate PDP) or dedicated app. No native Factur-X module.
- Prestashop: third-party modules or Pennylane connection. More flexibility, more setup.
For the full picture, see our 2026 e-invoicing guide for SMEs.
2. VAT, OSS and IOSS: which is easier to set up?#
| Criterion | Shopify | Prestashop |
|---|---|---|
| Default EU VAT rates | Auto-updated | To audit annually |
| OSS switch at EUR10k threshold | Built-in Tax module | Official OSS module to enable |
| IOSS (parcels ≤ EUR150 from outside EU) | Third-party app | Dedicated module |
| OSS mention on invoice | Native | Manual config |
| Continuous invoice numbering | Guaranteed by Shopify | To audit (tests, drafts) |
CPA verdict: Shopify is faster to bring into VAT compliance. Prestashop is solid but needs a yearly audit — see our Prestashop CPA 2026 guide.
3. PSP and marketplace reconciliation#
Both platforms integrate Stripe, PayPal and Shop Pay. The gap is in export granularity:
- Shopify: granular CSV export, line-level fees, native integration with Sqalie and Pennylane
- Prestashop: leaner exports by default, third-party modules required for clean PSP fees
For multi-PSP cases (Stripe + PayPal + Alma), Shopify simplifies three-way reconciliation. On Prestashop, Sqalie closes the gap.
4. Accounting connectors (Pennylane, Sqalie)#
| Connector | Shopify | Prestashop |
|---|---|---|
| Pennylane | Native | API or middleware |
| Sqalie | Direct | Direct (since 2025) |
| Qonto | Indirect via Pennylane | Indirect via Pennylane |
| Dext | Indirect | Indirect |
On both CMS, the Pennylane + Sqalie stack remains our recommendation.
5. Total annual cost: the real figure#
For a 600 orders/month, EUR1m revenue, 4 EU countries e-commerce:
| Item | Shopify | Prestashop |
|---|---|---|
| CMS licence | ~EUR1,800/yr (Shopify Basic) | EUR0 (open source) |
| Hosting | Included | EUR600 to EUR2,400/yr |
| Modules / apps | EUR1,200 to EUR3,600/yr | EUR1,500 to EUR4,000/yr |
| VAT setup audit | Light (EUR500) | Medium (EUR1,500-3,000) |
| Pennylane / Sqalie connectors | Included | Included |
| CPA fees | EUR250-600/month | EUR250-600/month |
| Yearly total excl. CPA | EUR3,500 to EUR6,000 | EUR3,600 to EUR9,400 |
At equal volume, Shopify is slightly more predictable on cost. Prestashop becomes more competitive above 5,000 orders/month when Shopify app costs spike.
6. Recommendation by profile#
- Launch / simple DTC, 0 to 500 orders/month: Shopify Basic, fast setup.
- Multi-EU, 500 to 5,000 orders/month: Shopify or Prestashop, Sqalie + Pennylane audit required.
- Highly technical catalogue, strong B2B, custom modules: Prestashop, mandatory annual audit.
- Marketplaces (Amazon FBA, Cdiscount) on top of Shopify/Prestashop: Sqalie essential, see our Sqalie channel margin guide.
7. FAQ#
Which platform is best prepared for 2026 e-invoicing? Neither is 100% native today. The plug-in goes through Pennylane (candidate PDP) or a third-party PDP. Shopify is slightly ahead on plug-in simplicity.
Can we switch CMS without accounting risk? Not without preparation. Migration impacts invoice numbering, VAT history, quarterly OSS. Our firm pilots the switch to preserve accounting continuity.
Does Sqalie work with both? Yes. Sqalie connects to Shopify, Prestashop, Amazon, Stripe, PayPal and Pennylane. It is the common analytical layer, see Sqalie.
Is Prestashop less reliable for VAT? No, but it requires more manual setup and a yearly audit. Shopify ships up-to-date EU VAT rates by default.
How much does a CMS scoping audit cost? EUR1,500 to EUR4,000 excl. VAT depending on complexity. The cost of avoiding a EUR18,000 VAT correction.
