Case Study: Large Payment Service Provider achieves threefold cross-border conversion rate increase with ACI Worldwide

PSP Success Enabling a Threefold Cross-Border Conversion Rate Increase

Large Payment Service Provider had launched a new cross-border eCommerce offering but saw merchant conversion rates stuck at about 23% despite available tools. They engaged ACI Worldwide for expert analysis and to apply ACI’s payment-platform capabilities, including fraud/risk guidance and its data validation tools, to diagnose why buyers in new markets were abandoning transactions.

ACI Worldwide identified four root causes — an overly strict 3‑D Secure setup, merchants misusing payment data fields, overreliance on CSCs in some countries, and lack of pre-submission data validation — and guided precise fixes. Implementing BIN-based 3‑D Secure bypasses for Brazil, stopping automated internal tags, disabling CSC prompts where inappropriate, and deploying ACI’s data validation raised merchant conversion rates from ~23% to nearly 72% while reducing acquirer and fraud-provider rejections.
