From first call to first order

Building an online store doesn’t have to take months or cost a fortune. We follow a straightforward process that gets you from idea to accepting orders quickly. No unnecessary delays, no hidden steps, just honest work that gets your store live.

01

Discovery Call

Tell us what you’re selling and who you’re selling to. We’ll figure out which platform works best and what features you actually need.

02

Design & Development

We start building your store based on everything we discussed. You’ll see the progress as your store takes shape week by week.

03

Quality Testing

We go through the entire buying process ourselves. Place test orders, check mobile screens, verify payment flows. Everything needs to work smoothly.

04

Store Launch

Your store goes live and starts accepting real orders. We monitor everything closely during the first week to ensure smooth operations.

People Are Shopping Online Every Single Day

If you’re not selling online, you’re missing out. Your customers are already buying products on the internet, just not from you yet.

We've built enough stores to know what actually matters.

Most agencies will promise you the world. We focus on what actually drives results: stores that load fast, checkouts that work smoothly, and designs that guide customers to buy. The Big Growth is an official Shopify Partner, and we also build on WooCommerce. See our Shopify web development, WordPress development and web design services.

01.

We Know What Kills Sales

Slow loading, confusing menus, hidden costs at checkout, tiny mobile buttons. We’ve seen every mistake that makes customers leave without buying. Your store won’t have those problems.

02.

Honest About What You Need

Not every business needs a fancy custom store. Sometimes a solid Shopify setup is smarter. We’ll tell you what makes sense for your budget and products, not what makes us more money.

03.

Available When Things Go Wrong

Payment gateway down? Product images not loading? Customer can’t checkout? These things happen. When they do, you can reach us. We don’t ghost clients after launch.
