How Bump Launched Above a 4% Conversion Rate on a Custom Store
The Starting Point
Most online stores launch and quietly underperform. The industry benchmark for eCommerce conversion sits around 2% — meaning 98 out of every 100 visitors leave without buying. Founders accept that number because they don't know it can be different.
Bump, founded by Jack Sachs, came to us before that pattern could set in. The product was real, the brand had potential, and Jack wanted a store that would actually sell — not a template stretched over a vision it was never built for. We built Bump's custom eCommerce website from scratch: the product presentation, the brand, and the checkout flow, all designed around one job.
The result: Bump launched above a 4% conversion rate, well above the typical ~2% eCommerce benchmark — right out of the gate. No long ramp-up. No "we'll optimize it later." It converted from day one because it was built to convert from day one.
What We Found
When we looked at what a generic template would have done to Bump, the gaps were obvious. A theme off the shelf is built to fit everyone, which means it fits no one in particular. The specific problems a default store creates:
- The product isn't explained, it's just displayed. Templates assume the visitor already knows what they're looking at. A new brand can't make that assumption.
- The brand gets flattened. Stock layouts reduce a distinct brand to the same hero-image-and-grid that thousands of other stores use.
- The checkout adds friction instead of removing it. Extra steps, unclear pricing, and unnecessary fields quietly bleed conversions at the exact moment a customer has decided to buy.
- Nothing is built around a decision. A template organizes content. It doesn't move a visitor from "interested" to "purchased."
The Strategy
We didn't start with "what should this look like." We started with "what does a visitor need to understand and do." Everything was built backward from the purchase decision.
Pillar 1 — Make the product instantly understandable
A visitor decides in seconds whether they get what you're selling. We built Bump's product presentation to answer the unspoken questions — what it is, why it matters, and what it does for the buyer — before the visitor has to go looking. Clarity, not cleverness, is what converts a first-time visitor.
Pillar 2 — Let the brand do the persuading
A custom build let us turn Bump's brand into an asset instead of decoration. The brand carries trust: it tells the visitor this is a real company that stands behind a real product. We designed the brand experience so that credibility was felt on every screen, not claimed in a paragraph nobody reads.
Pillar 3 — Make the checkout effortless
The checkout is where intent either becomes revenue or evaporates. We built Bump's checkout flow to remove friction at the decision point — clear, direct, and fast, so a customer who has decided to buy is never given a reason to reconsider. Every removed step is a recovered sale.
Pillar 4 — Build it custom, on purpose
None of the above is possible inside a rigid template. Building from scratch meant the product story, the brand, and the checkout could all be designed to work together toward the same outcome — instead of fighting the constraints of a layout someone else designed for a different business.
The Results
The numbers from the launch:
- Bump launched above a 4% conversion rate — well above the typical ~2% eCommerce benchmark.
- Roughly double the industry standard, on day one — no optimization period required to get there.
- Product, brand, and checkout aligned into one flow customers could understand and act on, in the founder's own words.

Why It Worked
Conversion-first design beats good-looking design
A store that looks impressive but doesn't convert is an expensive brochure. We designed every element of Bump's store against a single question — does this help the visitor understand and act? A beautiful page that doesn't move someone toward a purchase is a failure dressed up as a win. Conversion-first design inverts the priority: function first, and the polish serves the function.
Clarity is the highest-leverage lever you have
The fastest way to lose a sale is to make the visitor work to understand you. Most stores lose customers not because the product is wrong but because the product was never made clear. When the product, the brand, and the price are obvious, the visitor's only remaining decision is whether to buy — which is exactly the decision you want them focused on.
Custom isn't a luxury — it's how the pieces align
The value of building from scratch isn't aesthetics. It's that the product story, the brand, and the checkout can be engineered to pull in the same direction. In a template, those three things are bolted together and often work against each other. Custom is what let Bump launch at a conversion rate most stores never reach.
Get it right at launch, not after months of patching
Bump didn't crawl toward 4% over a year of tweaks. It launched there. Building conversion in from the start beats trying to retrofit it onto a store that was structurally working against you — every week a leaky store is live is revenue you never recover.
For Your Business
If you're launching a store — or relaunching one that isn't converting — the lesson from Bump is direct: the platform isn't your problem, and a prettier theme won't fix it. The question is whether your store makes the product obvious, makes the brand believable, and makes the checkout effortless.
A 2% conversion rate isn't a law of nature. It's what happens when those three things are left to a template. If your traffic is fine but your sales aren't, you're almost certainly losing customers in the gap between "interested" and "bought" — and that gap is fixable. It's the most profitable thing you can fix, because it makes every dollar you already spend on traffic worth more.
FAQ
What is a good conversion rate for an eCommerce store?
The typical eCommerce conversion rate sits around 2%, so anything meaningfully above that is strong. Bump launched above 4% — roughly double the benchmark — because the store was designed around clarity of product, brand, and checkout from the start. The right target depends on your category, but most stores have far more room to improve than they assume.
Is a custom eCommerce website worth it over a template?
A template is faster to launch, but it forces your product, brand, and checkout into a layout built for everyone else. A custom build lets all three work toward the same goal — getting the visitor to understand and buy. For Bump, that's the difference that produced a launch conversion rate double the industry norm.
Why does my store get traffic but few sales?
That gap almost always lives in clarity and checkout, not traffic. If visitors don't immediately understand the product, don't trust the brand, or hit friction at checkout, they leave even when they were ready to buy. Fixing those three things is usually the highest-return change you can make to an existing store.
