180 days. No payouts. The four cash-flow moves that bridge an AI company through a Stripe reserve hold — pulled from real workouts in 2025, with the numbers that worked.
Reverse charge can collapse 19% VAT to 0% for B2B EU sales. The catch: you need a verified VIES VAT number for every customer. We map the verification flow and the fallbacks when it fails.
OSS, Non-Union OSS, IOSS. Three EU schemes with overlapping scope and very different filing cadences. A practical guide to which one your AI co actually needs to file under.
Six signals trip Stripe's risk underwriting for AI companies. We walk each one with the data Stripe sees, the threshold it likely uses, and the concrete fix that takes you below the line.
Before 2018, you needed offices in a state to owe sales tax there. After 2018, you don't. The 8-year map of how that rule reshaped SaaS — and which states are still moving the goalposts.
$100k or 200 transactions. The thresholds look simple. The 21 states that interpret them their own way are not. The actual triggers AI companies hit, and how to model your exposure today.
Stripe Billing meters seats well and events badly. We trace what breaks when you put GPT-4o on Stripe's metered billing, and the four primitives an AI-first MoR ships in their place.
We've watched eight AI companies get paused by Stripe in 2025. The pattern is the same every time. Here's the 72-hour playbook: what to send Stripe, what to ignore, and when to migrate.
26 presentment currencies, dozens of indirect tax regimes, and a thousand ways to register late. The map of where AI companies actually owe VAT — and the cost of finding out a year after you did.
Stripe Tax computes the rate. You still owe the tax. We walk through the 1099-K problem, economic nexus thresholds, and where Merchant of Record cleanly cuts your exposure to zero.
