Case Study: Paraná Lentes achieves 35% cross-border sales growth and zero fraud chargebacks with ClearSale

Contact Lens Merchant Sees Clearer Path to Growth with ClearSale

Paraná Lentes, a contact-lens merchant in Paraná, Brasil, was losing focus to fraud management as it expanded card-not-present (CNP) sales into 150+ countries. The company needed a fraud-prevention partner that could protect cross-border transactions, avoid false declines across multiple time zones and languages, and preserve customer service—so Paraná Lentes engaged ClearSale and its Total Guaranteed Protection service.

ClearSale implemented Total Guaranteed Protection to screen every order, verify flagged transactions, provide real-time decisioning and reporting, and cover 100% of chargeback-related costs. The result: a 31% rise in overall transactions and a 35% increase in cross-border transactions in the first three months, a 97% approval rate for cross-border orders, guaranteed decisions up to $25,000, and zero fraud-related chargeback costs—freeing Paraná Lentes to focus on launching its own brand of lenses.
