Situation
Where they started
Northform Supply runs a Shopify store doing steady six-figure monthly revenue, with roughly 70% of traffic on mobile.
Problem
What was blocking growth
Their checkout took over 4 seconds to become interactive on mid-range phones. Analytics showed a sharp drop-off between cart and payment — a pattern that reads as friction, not intent. Two heavy third-party apps were loading blocking scripts on the checkout path.
What we did
The work that moved the numbers
- Audited the checkout render path and isolated two blocking third-party scripts.
- Replaced one app with a lightweight native alternative and deferred the other.
- Rebuilt the cart-to-checkout transition to remove a full page reload.
- Preloaded critical fonts and inlined above-the-fold styles.
They didn't just tell us the site was slow. They told us which two scripts, why they were blocking, and what each one cost us. Then they fixed it.
