Removing barriers to global ecommerce growth. Your 10-step guide to compliant commerce.

Why global ecommerce growth demands a compliance strategy 

Cross-border ecommerce is growing fast. Nearly 71.8 million US consumers made international online purchases in 2024, and Europe's top five economies are projected to post €2.5 trillion in retail sales by 2027. The opportunity is real, but so is the complexity. 

Expanding into new markets means navigating unfamiliar tax systems, invoicing requirements, and registration thresholds. Companies that enter without a plan often find themselves scrambling to catch up. Non-compliance can trigger audits, financial penalties, and damage to your brand reputation. 

US sales tax vs. European VAT: two very different systems 

The US and Europe take fundamentally different approaches to taxing goods and services. In the US, sales tax is a one-time charge applied at the point of sale, with rules set independently by each state, county, and city. That means thousands of jurisdictions, each with its own rates, exemptions, and filing deadlines. 

In Europe, Value Added Tax (VAT) applies at every stage of the supply chain, from producer to end consumer. Each country sets its own VAT rates and registration thresholds. EU member nations must charge a minimum 15% VAT rate, and many are rolling out new real-time reporting obligations that go beyond traditional VAT returns. Getting these calculations right matters: collecting too little or too much tax carries serious financial and legal consequences in both regions. 

Invoicing compliance adds another layer 

As your business expands across borders, invoicing requirements become more complex. Digital invoices must meet jurisdiction-specific formatting rules. Electronic invoices (eInvoicing) must be transmitted as structured, machine-readable data files in near-real time. Requirements vary significantly by country, and failure to comply can result in lost business and penalties.
