- Use Stripe as the only gateway for all your international traffic, and you will see alarming drops in acceptance rates, meaning the chance of successfully charging a Mexican customer in Mexico with a US Stripe account is much lower than if you have a local acquirer. By a lot!
- Rely heavily and blindly on Stripe Radar for post-charge suspected fraud alerts charges, and you will be refunding many valid orders.
- If you go all in with Stripe Checkout, you are getting a lot of good stuff at a price. If stripe dynamically uses 3DS to sift potential fraud users, you are going to hurt your conversion rates.
Been a big fan of Stripe for a long time, but when order volume goes up, and you grow internationally you have to consider other alternatives and/or backup plans, such as smart routing, local merchants, alert networks (ethoca, verifi), pre-checking for pseudo 3DS charges (no auth need, but fully protected, etc)
Not taking into account these 3 things, can drop your conversions by big double digit percentages.
