In this episode, Lucas and Luna dive into Stripe's latest architectural overhaul: rebuilding its core accounting and tax-computation engine to handle real-time sales-tax, VAT, and GST across more than 130 jurisdictions. They trace the engineering decisions behind moving from a batch nightly ledger to a streaming event-sourced system capable of recalculating tax lines mid-transaction without blocking checkout. Key numbers: Stripe processes over $1 trillion in payments annually, and the new engine runs 47,000 tax rules on average per transaction in under 12 milliseconds. Lucas explains the trade-off between eventual consistency and audit-grade accuracy, and why they chose Apache Kafka plus a custom FSM over off-the-shelf ERP middleware. Luna pushes back on the cost of maintaining 130+ rule sets and asks whether Stripe should have opened a public tax-engine API earlier. The episode ends with a reflection on whether tax compliance is the next infrastructure layer that every fintech will need to build or buy. #Stripe #TaxCompliance #AccountingEngine #RealTimeTax #EventSourcing #ApacheKafka #FintechArchitecture #GlobalPayments #VAT #SalesTax #StreamingLedger #TechInfrastructure #BusinessAndTechnology #CTOPodcast #EngineeringOrg #SystemDesign #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo
