our call
Start with FastSpring — highest vibe code, weakest moat.
FastSpring
FastSpring is not just checkout software; it assumes legal and financial liability as the Merchant of Record. Rebuilding the checkout UI in React is trivial, but self-hosting global VAT/GST compliance, localized payment acquirers, and fraud liability requires massive legal infrastructure.
you can rebuild
- Embeddable checkout UI modal and hosted payment pages
- Basic subscription management and recurring billing webhooks
- License key generation and digital file fulfillment triggers
- Customer portal for invoice downloads and subscription cancellations
- Multi-currency storefront price conversion displays
what you lose
- Merchant of Record legal status and cross-border indirect tax liability assumption
- Automated VAT/GST calculation, collection, and filing across 200+ global jurisdictions
- Global payment gateway routing, localized payment methods (iDEAL, Pix, Alipay), and acquirer optimization
- Merchant-level chargeback and fraud liability protection
- Payer of record status handling international currency conversion payouts
real moats
- Global legal and tax registration network with local tax authority filings
- Underwritten acquiring bank relationships and payment processing infrastructure
- Financial liability indemnification for chargebacks, VAT audits, and sanctions checks

Loqate
Building an autocomplete UI widget with an LLM takes two hours, but Loqate licenses official postal datasets (USPS CASS, Royal Mail PAF) across 240+ countries. Rebuilding this requires millions in raw data licensing fees and continuous syncs with international postal authorities.
you can rebuild
- Frontend checkout address autocomplete dropdown UI
- Client-side checkout field auto-population
- ISO country code and state abbreviation normalization
- Basic fuzzy matching for user address typos
- Basic Lat/Lng reverse geocoding wrappers
what you lose
- USPS CASS-certified delivery point validation (DPV) down to sub-building/suite units
- Royal Mail PAF (Postal Address File) official UK lookup data
- Direct updates from 240+ national postal databases for new construction and redistricting
- Multi-script address parsing (e.g., converting Kanji or Cyrillic to deliverable Latin shipping labels)
- Carrier deliverability risk scores (vacant, commercial vs. residential, undeliverable flags)
real moats
- Exclusive official data licensing agreements with 240+ national postal authorities
- USPS CASS and Royal Mail PAF regulatory compliance certifications
- Continuous ingestion pipelines processing millions of international postal data updates daily
