OctoCodes: Shopify Partner for custom apps, themes, and integrations

Since 2017, we have helped brands across Latin America, the United States, Canada, the UK, and other markets solve Shopify with deeper technical execution: custom apps, custom themes, automation, integrations, and ongoing evolution.

Shopify Partner

Technical Shopify work for teams that do not want to improvise.

At OctoCodes, we do not compete to be just another broad agency. While much of the market leads with store setup, performance marketing, or surface-level redesigns, we focus on Shopify’s technical layer through private and public apps, custom Shopify themes built from tailored designs, deep customization of existing client themes, ERP, CRM, POS, WMS, and 3PL integrations, automation, technical support, and performance work.

Clear Shopify offers for teams that need real technical depth

We have repositioned our offer around what we do best: Shopify technical work. We design, build, and maintain solutions for stores that require custom apps, custom themes, existing theme customization, integrations, automation, and performance work.

Clients trust OctoCodes when Shopify stops being a simple store project and becomes an operation that requires real technical judgment, delivery continuity, and solutions built to support growth.

Custom Theme Design & Development

We design and develop custom Shopify themes based on Figma files, tailored design systems, or your brand's visual direction. We turn a bespoke design into a functional, scalable, and conversion-ready storefront.

Integrations & Automation Pack

We connect Shopify with ERP, CRM, tax flows, POS, WMS, 3PL, WhatsApp, subscriptions, and reporting systems. We also design automations that reduce manual work and keep operations aligned across tools.

Custom Shopify App Build

We build custom Shopify apps that extend the admin, power specialized workflows, and solve needs generic apps cannot cover. From internal tools to scalable productized app experiences, we build around the way your business actually operates.

Existing Theme Customization & Extensibility

We customize existing client themes far beyond basic edits: new sections, layouts, visual logic, custom components, UX/CRO improvements, and technical upgrades that make the storefront match exactly what the business needs.

Ongoing Shopify Support & Growth

We become your ongoing technical team for releases, QA, app maintenance, integrations, performance work, and continuous improvements across your Shopify ecosystem.

" The work with OctoCodes was agile, the solution we were looking for was 100% met. The staff that provided us with customer service was quite assertive in every comment and observation. The requirement exceeded expectations.

Oddball

" I would like to give my strongest recommendation to Octocodes. They did an outstanding job and delivered a truly high-quality service.
From the beginning, their team dedicated the time needed to understand our needs, made thoughtful recommendations, and consistently provided solutions that exceeded our expectations. Their level of professionalism and commitment was exceptional throughout the entire process.
I was also pleasantly surprised by their pricing, which was very accessible considering the quality of the work they delivered.
Honestly, I would advise anyone looking for help with Shopify not to look elsewhere. Before working with Octocodes, I hired two different companies and unfortunately only ended up losing time and money. Shopify can be complex, and many companies simply do not have the specific experience required.
If you are looking for real expertise and reliable support, do not hesitate to work with Octocodes. I highly recommend them.

Chilly Mouth Experience

" The Octocodes team is LEGIT. Speaking from experience, choosing a developer to build our store is stressful. We spent 12 months developing our product and getting the branding dialed in. Then it came time to build our Shopify store which is arguably one of the most important parts of the customer journey. There are so many Shopify developers out there. A bunch of questions came up. Which one is going to do a good job? Which one is going to be affordable and not charge for little updates? Which one can we communicate with? Which dev can hit our deadline? Ultimately we decided on Octocodes and I'm glad we did. They finished the project on time and on budget and did a great job. We came up with some pretty custom design ideas and they were able to implement them from a dev standpoint without any issues. If you're reading this you're probably going through the same decision tree. Look no further, Javier and the Octocodes team are a good choice.

" Excellent experience with the OctoCodes team! They helped us optimize several key aspects of our Shopify store. They improved the structure of our products section and menus, achieving much more intuitive navigation for our customers. It also performed a header optimization, making the site look cleaner and more professional. Additionally, the display of reviews is now more attractive and easier to read, which has increased the trust of our customers. The visual restructuring of some popups has significantly improved the user experience. We were very pleased with the results and would definitely recommend their services to any business looking to optimize and improve their Shopify store. Great job!
