S4 Lights faced revenue leakage due to Shopify rounding prices down on the cart, checkout, and receipts. Products with prices like 16.54 or 23.79 were automatically rounded down, causing silent per-item losses that scaled with volume.
The Challenge
Thousands of SKUs and regular order volume meant consistent revenue loss. The goal was to stop this leakage without altering Shopify core behavior or manually editing the catalog.
Our Approach
- Audited the full product catalog
- Identified all price points affected by rounding
- Designed a scalable frontend solution for consistent pricing across all purchase flows
The Solution
Implemented a JavaScript-based price normalization logic that rounds prices up instead of down, e.g., 16.54 → 16.55. This logic is applied across:
- Product pages
- Cart
- Checkout
- Order confirmation and receipts
The solution was programmatically applied to thousands of products, eliminating manual edits and ongoing maintenance.
Results
- 100% elimination of per-item revenue loss
- Consistent pricing from product page to receipt
- Scalable pricing logic across the catalog
- Predictable margins on every order
Takeaway
The S4 Lights Shopify rebuild (OS 2.0) included new visuals and a multi-catalog setup for retail, wholesale, and B2B. The key challenge was Shopify’s rounding behavior from NetSuite decimal prices, which we solved with a price-normalization layer, keeping pricing logic, catalog, and ERP sync clean and maintainable.
