our call
Start with Taxually — highest vibe code, weakest moat.
Taxually
While aggregating sales data to compute VAT liability is easy to code, Taxually's true value is regulated tax filing and legal compliance with government tax authorities across Europe. AI cannot act as a certified tax agent, hold power of attorney, or legally submit tax returns directly to foreign government portals.
you can rebuild
- Aggregating transaction data across Shopify, Amazon, and WooCommerce for tax reporting
- Categorizing sales by destination country to track EU OSS (€10,000) threshold progress
- Applying historical EU and UK standard, reduced, and zero VAT rates to order line items
- Validating EU B2B customer VAT numbers against the VIES API web service
- Generating internal monthly CSV summaries of tax liabilities per country
what you lose
- Direct electronic filing to national tax authority portals (HMRC, ELSTER, DGFiP, etc.)
- Legal fiscal representation in EU countries where foreign merchants require local agents
- Guaranteed legal compliance and liability coverage for miscalculated returns
- Automatic maintenance of changing EU member state tax rates and reporting XML schemas
- Dedicated human tax professionals to respond to government audits and notices
real moats
- Official software accreditation and direct submission pipes with national tax offices
- Legal capacity to act as an accredited fiscal representative in international jurisdictions
- Direct API credentials and auth tokens issued by government finance ministries

Zonos
Zonos is fundamentally a regulatory data product combined with financial risk underwriting. While rendering an estimated duty at checkout is trivial, maintaining real-time global HS code schedules, de minimis rule changes across 200+ countries, and absorbing customs underpayment risk cannot be automated with LLMs.
you can rebuild
- Checkout widget UI displaying calculated import duty and tax line items
- Basic multi-currency display and real-time exchange rate conversion
- LLM-assisted initial 6-digit Harmonized System (HS) code tagging on store SKUs
- Estimation of baseline regional VAT/GST percentages
- Merchant dashboard showing cross-border sales volume by country
real moats
- Maintained database of global 6-to-10 digit HS codes, trade agreements, and regional de minimis rules across 200+ jurisdictions
- Financial liability assumption (Duty Guarantee) protecting merchants from unexpected customs fees
- Global tax registration and remittance infrastructure (e.g. EU IOSS, UK VAT, AU GST)
