Development of an AI-Driven Cross-Border VAT and Tax Calculation Platform for E-Commerce Shopify Integrations

E-commerce businesses operating across borders often encounter complex and varied VAT regulations in different countries, leading to administrative burdens, compliance risks, and potential financial penalties. The manual process of calculating duties and taxes at checkout, especially with discount applications and diverse product categories, further complicates tax compliance. An efficient, automated solution for real-time VAT calculation, legal declaration, and seamless integration with online platforms is needed to reduce errors and administrative overhead.
