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
open source escape hatches
- Kill Bill Apache-2.0
- Lago AGPL-3.0
- Hyperswitch Apache-2.0
Global-e
Global-e is primarily a Merchant of Record (MoR) and cross-border regulatory provider, not just a software overlay. While you can easily code a multi-currency checkout frontend with AI, you cannot code local tax registrations in 180 countries, customs clearance agreements, or FX risk hedging contracts.
you can rebuild
- Multi-currency price rounding and display logic
- Geo-IP country detection and checkout localization
- Localized checkout field formatting and address validation UI
- Basic front-end duty and tax estimation UI widgets
- Integration with third-party payment gateways for basic foreign card handling
what you lose
- Merchant of Record status and legal tax liability indemnification
- Global tax entity registrations (VAT/GST compliance) in over 180 markets
- Pre-negotiated international courier rates and duty drawback processing
- FX rate risk hedging and localized foreign currency payout management
- Local payment method acquiring networks that increase approval rates
real moats
- Merchant of Record legal entity network across global tax jurisdictions
- Established volume-discounted agreements with international logistics carriers and customs brokers
- Direct local payment acquiring relationships that boost cross-border conversion
