PayPager aims to recover potentially lost revenue by providing merchants with early alerts regarding payment failures, particularly in cross-border transactions. Its core strength lies in proactive identification of issues like 'do not honor' errors and card declines, giving merchants a chance to intervene and secure sales before abandoned checkouts officially register.

It aims to increase average order value through product recommendations, post-purchase offers, and thank you page customization. UpsellPlus targets merchants who want to proactively increase their AOV with checkout and post-purchase upsells, and who potentially have Shopify Plus to take advantage of all features. The tool has a strong social presence, considering it supports checkout upsells, and allows for customization of social checkouts, like Facebook, Instagram, and TikTok. PayPager appeals to merchants, particularly those engaged in international sales, who want to minimize revenue loss due to payment processing issues. A key differentiating factor is that PayPager's value is centered on recovering potentially lost sales due to card declines, where as, UpsellPlus focuses on increasing the value of each sale via upselling opportunities. In terms of social proof, UpsellPlus is the clear winner due to having 103 reviews and a perfect 5/5 star rating. PayPager has zero reviews and a 0/5 star rating.
