Case Study: Master English reduces chargebacks by 55% with Paddle

How Master English reduced its chargeback rate by 55% in two months by partnering with Paddle

Master English, an AI-powered app that helps Spanish-speaking adults improve their English, partnered with Paddle to support web subscriptions alongside app store sales. As the company scaled, it needed a merchant-of-record partner to handle global payments, taxes, refunds, and chargebacks, and it also began noticing rising chargebacks—especially on long-term subscriptions in the US.

Paddle worked with Master English’s team to analyze the issue and implement changes such as moving the US market to monthly-only subscriptions, improving billing communications, extending app session length, adding pre-billing notifications, updating statement descriptors, and emailing at-risk subscribers. With Paddle’s help, Master English reduced its overall chargeback rate to 0.53% from 1.12% in two months, cut US Visa chargebacks by 55%, and lowered total chargeback count by 54% while continuing to grow web revenue.
