When to choose Affirm
Affirm is the recommended choice for established online merchants who require a proven, loan-based payment infrastructure. With a site count of 66 and 67 total detections, it offers the stability and consumer trust necessary for high-volume e-commerce. It is particularly suited for businesses selling high-ticket items—as seen with its adoption by bugaboo.com and callawaygolf.com—where providing customers with fixed monthly payment options is a critical conversion factor. If your technical requirement involves a verified integration with a major loan provider, Affirm is the only viable option in this pair.
When to choose Four
Four is currently only a consideration for merchants looking to experiment with emerging Buy now pay later solutions that have not yet achieved broad market adoption. Given its current site count of 0, it may appeal to early-stage startups or niche platforms that are specifically seeking the "Pay with four" model and are willing to be among the first to implement the technology. However, without any detections or a sample of top sites, choosing Four involves a higher degree of technical uncertainty compared to the established footprint of Affirm.
