Sell more than Amazon lets you.
On Amazon you sell one unit, once. We build the Shopify store that sells bigger orders, and sells them again. Live in 7 days.

Then the second, third and fourth
On Amazon it’s one order, and Amazon keeps the customer. Here they come back to you.
How we bring buyers backOn the page
3-pack first
The bigger pack is the default offer.
In the cart
One add-on
Plus a free-shipping bar above the average order.
After the order
You own the email
A reorder reminder lands before they run out.
Every month
Subscription
The reorder happens by itself. No ad needed.
And on Amazon
Your store sends buyers to your listing too
Some shoppers land on your product page and still prefer to buy on Amazon. They go from your page to your listing, so you keep that sale too. We show both in one report.
Example with made-up numbers: a $40 product, a $102 3-pack and a $14 add-on. Your free store plan shows the same sum with your prices.
See where every visitor goes. And how they come back.
Your traffic lands on your pages. From the product page it buys on your store, or goes on to your Amazon listing. Pick a package to see which parts we build.

You talk to me, not an account manager.
I’m Nick Siwek. I’ve spent 12 years in ecommerce and worked with more than 200 brands, from fresh launches to products doing six and seven figures. I managed over $10M in ad spend for the largest Amazon aggregator, the 8th fastest-growing company in the UK in 2024, and spent two years at one of the best Amazon agencies in the industry.
I studied cognitive psychology, so my work starts with one question: what makes someone press Buy? BigBang answers it AI-first. We read every review before we plan a page, which is why your store plan takes days, not weeks.
Send us your listing. We’ll send you your store plan.
A page-by-page plan and a price by email, usually within two working days. No call needed.
