Everything Your Shopify Store Needs. One Team. No Gaps.
From the first design conversation to ongoing post-launch performance work, here’s what Sigma delivers for Miami businesses.
Shopify Store Setup, Theme Development & UI Enhancements

How We Work
Our Shopify Development Process
No black boxes. No shifting estimates. Every Sigma project follows a six-stage delivery process that keeps SF clients informed and on schedule.
01
Discovery & Strategy
We start with your customers, your systems, and your commercial goals—before any code is written. The brief drives every decision.
02
Theme Design & Customization
Custom or enhanced Shopify themes built for speed and conversion on every device. Design is approved before it goes to engineering.
03
App Development & Integration
Custom apps, ERP connections, payment integrations—built and tested as a complete working system, not assembled in the last sprint.
04
Quality Assurance & Testing
Full performance, security, cross-browser, and cross-device testing before launch. Your customers don’t find the bugs.
05
Store Launch & Deployment
Go-live is a planned, monitored event. Sigma handles deployment and stays on top of the first 48 hours.
06
Ongoing Maintenance & Optimization
We don’t exit after launch. Sigma stays on – monitoring, optimizing, and building as your Miami business grows
Why Sigma
Why Miami Businesses Choose Sigma for Shopify
Miami has no shortage of Shopify developers. What it does have a shortage of is certified partners who deliver properly, stay accountable, and don’t disappear after handover.
01
We build for revenue, not just for launch
Going live is the start. Sigma designs stores to convert traffic into customers and stays to keep improving that performance after the store is running.
02
A commerce partner, not a code vendor
Sigma aligns Shopify’s capabilities with how your business makes money. Every recommendation has a commercial rationale – not just a technical preference.
03
Fast stores. Fewer abandoned sessions.
Page speed and checkout friction are both revenue variables. Sigma builds Shopify stores that load fast, work across devices, and don’t put unnecessary barriers between a Miami buyer and a completed order.
04
Security and Compliance That Holds
ISO 27001:2022 certified. Every engagement includes security practices that protect customer data and support compliance with US and Florida data privacy requirements – through development, staging, and production.
Certifications
Certified. Not Just Claiming to Be.
In a city where people know what engineering credentials actually mean, we’d rather show them than talk about them. These are active certifications held by the engineers on your project.

Frequently Asked Questions
What does a Shopify development company in Miami do?
More than most expect. A Shopify development company builds stores, customizes Liquid themes, develops custom apps for workflows the app store doesn’t cover, connects Shopify to ERP and CRM systems, configures Shopify Plus for enterprise needs, handles platform migrations, and provides ongoing post-launch support. Sigma delivers all of this from structured delivery centers – not a freelancer pool that shifts with every engagement.
What Shopify certifications does Sigma hold?
Sigma is an active Shopify Partner with certifications in Shopify Foundations and Certified Liquid Storefronts for Theme Developers – earned and maintained by the engineers who do the actual work, not held at the company level and separate from the project team. Beyond those: Adobe Solution Partner (Bronze), AWS Certified Partner, Microsoft Silver Partner, ISO 27001:2022, and ISO 9001:2015. All actively renewed.
Can Sigma migrate our existing store to Shopify?
Yes – and it’s a process Sigma has run many times with a clear methodology. We migrate from Magento, WooCommerce, BigCommerce, and older custom-built platforms to Shopify and Shopify Plus. Every URL redirect is mapped to protect your organic rankings. All product data, customer records, and order history come across completely. You don’t discover what’s missing after go-live.
Does Shopify support bilingual stores for Miami’s English and Spanish-speaking customer base?
Yes. Shopify supports bilingual storefronts with language-specific URL structures, translated content, currency display, and localized checkout experiences. For Miami businesses selling to US and Latin American buyers simultaneously, Sigma configures the store to serve both audiences properly – including language detection, currency preferences, and regional payment options where needed.
How much does Shopify development cost in Miami?
It depends on what you’re building. A branded DTC fashion store is a different project from a Shopify Plus deployment with multi-currency support, B2B wholesale portal, and ERP integration. Sigma scopes every project carefully, provides a clear USD estimate before work starts, and holds to it. No estimates that shift when you get the invoice.
Can Sigma build a Shopify store that sells across the US and Latin America from Miami?
Yes. Miami is a natural hub for US/Latin America cross-market commerce, and Sigma has experience building for it. This typically involves multi-currency and multi-language configuration, country-specific payment methods, international shipping integrations, and hreflang and SEO structure to serve both markets effectively without splitting your organic authority.
Can Sigma build a headless Shopify store?
Yes. Sigma builds headless storefronts on React and Next.js using the Shopify Storefront API – suited to New York tech companies embedding commerce into an existing product, or fashion and luxury brands that need full design control and maximum page performance. Being honest about it: headless adds real architectural complexity and ongoing maintenance overhead. Sigma will tell you whether it genuinely fits your situation before recommending it.
Why choose Sigma over a local Miami Shopify developer?
Miami has capable local developers and we’re not pretending otherwise. What most local freelancers and smaller agencies can’t offer is a structured six-stage delivery process, dedicated QA, enterprise-grade security, and sustained post-launch support. Sigma is a certified Shopify Partner with 20+ years of commerce delivery and 400+ specialists across four delivery centers. You get a team that’s still accountable six months after launch.
