Our store was losing about 12% of international sales at checkout, and I had no idea why. Found this
payment acceptance guide that explained everything from issuer declines to network tokenization. The section on checkout optimization was gold: reducing fields and offering local payment methods boosted our approval rate by nearly 8% in a month. Also helped me understand why some cards get declined even when funds are available. If you're losing sales at the payment step, this is a must‑read.
