Shopify agency for Amazon brands

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.

Why your own store

Two numbers decide what a customer is worth. Your store moves both.

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 back

On 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 website feeds your Amazon listing too

Every product page carries a Buy on Amazon button under Shop now. Shoppers who prefer Amazon click through and buy there, so your own traffic becomes extra sales on your listing. Amazon ranks products on what customers buy, and its own advertising guide says off-Amazon campaigns that bring more visits to product pages “can help support organic rankings”. For brand-registered sellers in the US, Amazon also pays back about 10% of those sales on average.

Buy on your store14
Buy on Amazon15

Example for 1,000 visitors: 1.4% buy on the store (the Shopify median), 10% click the Amazon button and 15% of those buy. Your numbers will differ; we track both.

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.

The whole system

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 clicks Buy on Amazon and buys on your listing. Pick a package to see which parts we build.

Who you work with

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.
