Accounting for e-commerce site: points to master

Updated March 2026 - Accounting for an e-commerce site quickly becomes more complex than simple sales management. Between marketplaces, payment flows, refunds, VAT OSS/IOSS and interconnected tools, the real risk is not missing data, but not reconciling it correctly.

The most frequent areas of complexity

  • multi-channel sales;
  • platform commissions;
  • payment fees;
  • credits and reimbursements;
  • VAT depending on the country and sales pattern.

  • orders;
  • regulations;
  • commissions;
  • reimbursements;
  • VAT collected.

In the accounting professions, trust is built as much on technical rigor as on pedagogy and the clarity of the intervention framework.
