Prestashop powers more than 300,000 stores worldwide and remains one of the most-used open-source e-commerce platforms in France. Its flexibility is also its main accounting risk: third-party modules with no upstream maintenance, approximate VAT setups, heterogeneous accounting exports. Hayot Expertise supports Prestashop merchants on accounting, intra-EU VAT and the 2026 French e-invoicing reform.
Hayot Expertise — Prestashop, Shopify and marketplace specialists — operating from Paris and remotely across France.
1. Why a Prestashop-specialised CPA#
No Prestashop is generic: version (1.7, 8.x, 9.x), payment modules (Stripe, PayPal, HiPay), shipping modules, OSS/VAT modules, multistore setup. Each combination can create gaps between:
- revenue shown in the Prestashop back-office;
- payouts on Stripe, PayPal or Qonto;
- VAT declared on CA3 and OSS returns;
- accounting entries pushed to Pennylane, Sage or Cegid.
Our role: make the full chain auditable, from the Prestashop module to the year-end accounts.
2. Reconciliation Prestashop ↔ Stripe / PayPal / Pennylane#
Three flows must be reconciled monthly:
- Prestashop orders: paid, refunded, partially refunded.
- PSP payouts: Stripe ~1.4% + EUR 0.25 in the EEA, PayPal fees and chargebacks, consolidated bank transfers.
- Bank: Qonto or another business account.
Above 500 orders/month or 2 PSPs combined, we deploy Sqalie as the analytics layer and Pennylane as the accounting record. Reconciliation moves from manual (risky) to industrialised (auditable).
3. OSS, IOSS and territoriality rules#
For a Prestashop multistore selling into France and the EU:
- Above EUR 10,000/year of intra-EU B2C sales (article 259 D French Tax Code), OSS registration is mandatory and returns are quarterly.
- For imports below EUR 150 from outside the EU, the IOSS scheme simplifies VAT collection.
- Prestashop VAT modules must apply the destination-country rate above the OSS threshold — a frequently overlooked setting that triggers tax adjustments.
- Reference: BOI-TVA-CHAMP-20-20-30 and the official OSS portal at impots.gouv.fr.
We audit Prestashop tax rules before the first quarterly OSS return.
4. 2026 e-invoicing: configure Prestashop now#
The 2026 reform introduces B2C e-reporting and B2B e-invoicing via PDPs (accredited dematerialisation platforms). For a Prestashop store this means:
- Issue invoices in Factur-X format (PDF/A-3 + XML) or UBL via a module connected to your PDP.
- Transmit B2C data to the PPF (public portal) through your PDP.
- 10-year retention with timestamping and a reliable audit trail.
- Direct link with Pennylane, a PDP candidate.
We scope Prestashop ↔ PDP compliance ahead of the first reform-compliant flow.
5. Migration and module choices: field feedback#
| Topic | Common mistake | Hayot Expertise method |

| OSS VAT module | Free, unmaintained module | Official module or Sqalie + tax audit |
| Accounting module | Manual monthly CSV | API connector to Pennylane / Sage |
| Multistore | Mixed chart of accounts | Analytics axes per store |
| Refunds | Booked as expense | Credit notes and VAT adjustment |
| Inventory | No valuation in the books | Monthly stock via Sqalie |
Questions frequentes
Which accounting module should I pick for Prestashop?+
Is Prestashop compliant with the 2026 French e-invoicing reform?+
Not natively. You must add a module connected to a PDP, able to issue Factur-X and route flows to the PPF. We validate the module + PDP combination before deployment.
How do I handle OSS VAT on a Prestashop multistore?+
Each store must apply the destination-country rate above EUR 10,000/year of intra-EU B2C sales. The default Prestashop setup often applies a single rate: tax zones must be adjusted, an OSS module enabled, and consistency checked against quarterly OSS returns.
Prestashop or Shopify from an accounting standpoint?+
Prestashop offers more control (open-source, multistore, modules) but needs continuous technical maintenance. Shopify is more standardised but less flexible on OSS VAT and accounting exports. We arbitrate by volume, target countries and marketplace strategy — see our detailed comparison.
Can you support a Prestashop ↔ Shopify migration?+
Yes. We handle the accounting and tax track (cut-off, stock take, open credit notes, OSS, chart-of-accounts mapping). The technical migration is delivered with a specialised partner.
