A store we worked with was losing buyers at the worst possible moment — the checkout. Here's the short version of how we made it twice as fast, and what it did to their numbers.
The problem
The checkout took over 6 seconds to become interactive on mobile. Every one of those seconds was quietly costing sales.
What we changed
- Trimmed and deferred heavy third-party scripts
- Optimised and lazy-loaded images
- Streamlined the form to only essential fields
- Moved to a faster, edge-served setup
The result
Time-to-interactive dropped from ~6s to under 3s, and the client saw a meaningful lift in completed checkouts — same traffic, more revenue.
Speed isn't a vanity metric. On a checkout, it's money.
