Our Services
Everything Your Shopify Store Needs. One Team. End-to-End Ownership.
From your first design review to ongoing post-launch optimization, here’s what Sigma delivers for Austin businesses.
Shopify Store Setup, Theme Development & UI Enhancements
Austin’s consumer base is brand-aware and digitally native. They’ve shopped enough Shopify stores to know when one is fast, well-designed, and worth trusting—and when one isn’t. Sigma builds Shopify storefronts in custom Liquid that load fast, look exactly like your brand, and are structured to convert from the first visit, not after a round of post-launch fixes.
-
Responsive Liquid themes built from your brand identity—not adapted from a shared template library -
Custom Shopify store setup for B2B and B2C, built around Austin consumer expectations and US-native payment methods including Shop Pay, Afterpay, and Klarna -
SEO-clean, speed-optimized code that doesn’t create technical debt for your marketing team to deal with later -
Mobile-first storefronts connected to your analytics and marketing stack before go-live
Shopify Plus, B2B & Customization Services
Austin has a growing wholesale and B2B economy—tech companies with enterprise procurement processes, CPG brands managing retail and wholesale simultaneously, and outdoor brands running dealer networks alongside DTC. Standard Shopify wasn’t built for that kind of operational complexity. Shopify Plus was. Sigma configures it for businesses where B2B is a serious revenue channel, not a secondary one.
-
B2B trade portals with custom logins, tiered pricing, role-based access, and catalog restrictions per buyer segment -
Shopify Plus enterprise setup for omnichannel operations—DTC, wholesale, and retail working together -
Workflow automation and backend integrations built to handle the order volumes Austin’s scaling businesses generate -
Checkout.liquid customization for Plus stores—fewer steps and higher purchase completion rates
Shopify App Development Services
Austin’s tech-forward business culture means many of our clients arrive with specific operational requirements that the app store doesn’t cover cleanly. Sigma builds custom Shopify apps around your actual business logic—engineered properly, tested against real traffic volumes, and built to stay reliable as your Austin brand scales.
-
Custom apps for B2B and B2C workflows that prepackaged solutions don’t handle reliably -
Apps integrated with Shopify Flow, webhooks, and metafields—built as part of the platform, not as a workaround -
Performance-optimized code that doesn’t add page weight or create storefront latency -
Embedded analytics and reporting so your team has real visibility inside Shopify admin
Shopify App Integration Services
Running Shopify separately from your ERP, your 3PL, and your CRM creates manual work at every order. Austin’s fast-moving brands can’t carry that overhead. Sigma builds integrations that connect Shopify to your entire operation—so inventory, orders, and customer data stay accurate across every system automatically.
-
ERP, POS, CMS, CRM, and US payment gateway integrations including Stripe, Shop Pay, Klarna, and Afterpay -
Real-time order, inventory, and customer data sync—no end-of-day exports and no reconciliation spreadsheets -
Automated workflows that maintain data accuracy without constant manual oversight -
Shopify analytics and conversion tracking configured before go-live so your data is useful from day one
Shopify Checkout Customization & Optimization
Austin shoppers have high expectations and move on quickly. Missing payment options, multi-step checkout flows, or a mobile experience that doesn’t hold up all translate directly into lost revenue. Sigma fixes this at the Shopify Plus level, where the checkout can be rebuilt to match your brand and your buyers—not just restyled.
-
Shopify Plus checkout.liquid customization—Shop Pay, Afterpay, Klarna, and BNPL flows built for how US buyers actually pay -
Store-wide speed optimization, not just checkout-page fixes -
Infrastructure improvements so high-traffic periods—Black Friday, Cyber Monday, and Austin City Limits merch drops—don’t take the store down -
Funnel analytics and structured A/B testing so every optimization is measured, not guessed
Shopify Migration Services
Most Austin businesses that come to Sigma with a migration project have one non-negotiable: they’ve built organic search rankings over years and they can’t afford to lose them in the switch. That’s the right priority. Sigma has run enough migrations to know every failure point and how to prevent all of them.
-
Zero-downtime migrations from Magento, WooCommerce, BigCommerce, or older custom-built platforms -
Full URL redirect mapping so your organic search rankings hold through the platform transition -
Clean, verified transfer of every product, customer record, and order in your database -
Post-migration QA and monitoring—Sigma stays engaged after go-live until everything is confirmed working
Shopify Support & Maintenance Services
Launching well is one part of the work. Staying operational as your Austin brand scales—through platform updates, app conflicts, and traffic surges—is another. Sigma’s post-launch support handles all of it before your customers notice anything’s off.
-
Proactive monitoring and real-time issue resolution—not a support ticket queue reviewed between other projects -
App and platform updates managed before they create downstream compatibility problems -
Regular security audits and performance reviews aligned to your revenue growth targets -
Ongoing CRO and feature development as your store needs to do more

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
Sigma doesn’t exit after launch. We stay on – monitoring, optimizing, and building as your Austin business scales.
Why Sigma
Why Austin Businesses Choose Sigma for Shopify
Austin 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 beginning. Sigma designs stores to convert traffic into buyers and keeps improving 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.
03
Fast stores. Fewer abandoned sessions.
Page speed and checkout friction directly affect revenue. Sigma builds stores that load fast and don’t place unnecessary obstacles between a 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 data privacy requirement across development,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 Austin do?
More than most people expect. A Shopify development company builds stores, customizes Liquid themes, develops custom apps for workflows the app store doesn’t cover well, connects Shopify to ERP and CRM systems, configures Shopify Plus for enterprise requirements, handles platform migrations, and provides ongoing post-launch support. Sigma delivers all of this from structured delivery centers – not through a freelancer network.
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. 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 Magento or WooCommerce store to Shopify?
Yes – and it’s something Sigma has done many times with a clear process behind it. 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 search rankings. All product data, customer records, and order history come across cleanly. You don’t discover gaps after go-live.
Does Shopify work well for Austin’s DTC and CPG brands?
Very well – especially when it’s set up right for the category. For DTC brands, Sigma builds fast, conversion-focused storefronts with subscription support, loyalty integrations, and checkout flows optimized for repeat purchase. For CPG and food brands going direct, Sigma adds age verification, compliance messaging where required, and integrations with US-based 3PL and fulfillment providers. Shopify Plus is also the right choice for brands managing retail wholesale and DTC simultaneously.
How much does Shopify development cost in Austin?
It depends on what you’re building. A branded DTC store with a few integrations is a different scope from a Shopify Plus deployment with wholesale functionality, ERP integration, and custom app development. Sigma scopes every project properly, provides a clear estimate before work starts, and holds to it. No round numbers that grow at invoicing.
Can Sigma build a store that handles both DTC and wholesale on the same platform?
Yes. Shopify Plus supports both channels from a single store – with separate B2B portals, customer-specific pricing, restricted catalogs for wholesale buyers, and a full DTC storefront for direct customers. Sigma has configured this setup for brands running both channels and knows where the complexity sits before the build starts.
Can Sigma build a headless Shopify store?
Yes. Sigma builds headless storefronts on React and Next.js using the Shopify Storefront API – suited to Austin tech companies embedding commerce into an existing product, or brands needing maximum performance and full design control. Being direct: headless adds real architectural complexity and ongoing maintenance overhead. Sigma will assess whether it genuinely fits your business before recommending it.
Why choose Sigma over a local Austin Shopify developer?
Austin has strong technical talent – we’re not dismissing that. What most local freelancers and smaller agencies can’t offer is ISO 27001:2022 certified security practices, dedicated QA, a structured six-stage delivery process, 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 accountability that extends well past the go-live date
