How we cut a checkout from 6s to 1.2s
A store owner came to us losing sales on a slow checkout. Here's what we found, what we changed, and what it did to their numbers.
1. The problem
Their checkout took six seconds to load on a phone, and roughly a third of buyers dropped off before paying. The cause was the usual suspects — heavy images, blocking scripts, and a database query running once per cart item.
2. What we changed
We compressed and lazy-loaded images, deferred the non-critical scripts, and batched the cart query into one call. Checkout dropped to 1.2 seconds, and completed orders rose noticeably within the first two weeks. Want the same look at yours? Just reply.
