Cross-border EC Situation and Challenges in 2026-2027

As the market expands, regulations in various countries are entering a phase of "tightening and digitalization".

Enforcement of digital taxation

The capture of off-platform taxation will be strengthened around the world, led by the new smartphone law.

Electronic invoicing becomes mandatory

Digital invoices such as Peppol will become the standard, and analog tax processing will no longer be acceptable.

Expansion of environmental regulations (EPR)

Compliance with packaging laws, etc., is becoming mandatory, especially in Europe, and non-compliance will lead directly to immediate "sales suspension.

Customer Issues

I want to be entrusted with defining the requirements for the tax engine and putting it into practice.

Large company, business manager
The linkage between existing systems and overseas taxation is a black box.

My Amazon account has been frozen. I need to restore it now and resume sales.

Small business owners and managers
are unsure of local rules and the sudden suspension of sales is a matter of life and death.

I want to create a system where progress on overseas tax matters does not stop even if the person in charge quits.

Accounting and Finance Manager
The status of overseas subsidiaries and outsourcing partners is unclear and governance is not effective.
