How much does it cost to fix a WooCommerce checkout bug?

Most single, well-defined checkout bugs are a $99 Quick Fix (about 4 hours at $25/hr), turned around in 24-48 hours. A batch of related bugs or one gnarly root cause, like a Block-vs-shortcode conflict or a gateway 500, is the $499 Bug-Fix Sprint (about 20 hours) with full diagnosis and regression tests. High-volume stores that cannot risk downtime take an Emergency / Retainer with a $2,499 stabilization sprint option. You see the quote before any work starts.
