How much does it cost to fix a BigCommerce bug?

A single, well-defined BigCommerce bug starts at $99 (Quick Fix, ~4h @ $25/hr) with a 24-48h turnaround. A batch of bugs or one deep root cause, like a failing Stencil build or an unstable Checkout SDK flow, is the $499 Bug-Fix Sprint (~20h @ $25/hr). Down-store emergencies and ongoing cover are quoted as a retainer, with a $2,499 stabilization sprint (~100h @ $25/hr) available for deep rebuilds. You always get a fixed price before any work starts.
