Custom Shopify development that adds the features, logic, and integrations your store needs but the platform does not ship out of the box.
Benji's Digital is a Shopify development team that builds custom functionality on top of Shopify and Shopify Plus. We write custom apps, build Shopify Functions, develop headless storefronts with Hydrogen, and connect your store to the ERP, CRM, and PIM systems that run your business. When a theme or an app from the store cannot do what you need, we engineer it.
Shopify Partner Most Shopify projects start with a theme and a handful of apps. That works until your business outgrows it. When you need logic the platform does not support, data flowing between systems, or a storefront that behaves like a custom application, you need development, not another app subscription.
Shopify development covers everything that requires custom code on the platform. That includes custom app development, Shopify Functions, headless storefronts, checkout extensibility, API integrations, and custom data models built with metaobjects and metafields.
We build the parts of your store that have no off-the-shelf answer. A pricing rule no app supports. A real-time sync to your warehouse system. A product configurator your shoppers can use. A headless front-end that loads in a fraction of the time. These are engineering problems, and we solve them with maintainable, documented code.
A theme controls how your store looks and how merchandising is presented. Development controls what your store can actually do. The line is simple. If the work is layout, styling, and Liquid templating, it is theme work. If the work is custom logic, data integration, or new functionality, it is development.
We keep these scopes separate on purpose, because mixing them creates fragile stores. For the front-end build itself, see our Shopify theme development service, and when raw performance is the goal, our Shopify speed optimization service tunes the same store for Core Web Vitals. For the engineering that sits behind it, you are in the right place.
We cover the full range of custom Shopify engineering. Every build ships with clean code, documentation, and a handover your team can maintain.
We build custom Shopify apps that add functionality no public app provides. A custom Shopify app is a private application built only for your store, connected through Shopify's Admin API, Storefront API, and webhooks. Custom apps let you automate workflows, sync data, add admin tooling, and create customer-facing features that fit your exact process, with no monthly fees for features you do not use.
Shopify Functions let us run your custom business logic directly inside Shopify's infrastructure. A Shopify Function is a small program that executes at key points in the cart, checkout, and order flow, such as applying a custom discount, reordering payment methods, or hiding a shipping option. Functions replaced the old Shopify Scripts model and run faster and more securely.
We build headless Shopify storefronts using Hydrogen, Shopify's React framework for custom commerce front-ends. Headless commerce separates your storefront from the Shopify backend, so you control the entire shopping experience in code while Shopify still handles the cart, checkout, and orders. We pair Hydrogen with Oxygen hosting and the Storefront API for app-like speed and flexibility.
We customize Shopify checkout using checkout extensibility, the modern and supported way to add features to the checkout flow. Checkout extensibility is Shopify's framework of UI extensions and Functions that let developers add content, fields, and logic to checkout without editing checkout.liquid. For Shopify Plus merchants, we extend the information, shipping, and payment steps.
A growing store is never just a store. It is connected to the systems that handle your inventory, your accounting, your customers, and your fulfillment. We build the integrations that keep all of them in sync.
We connect Shopify to your ERP, CRM, and PIM systems so data moves automatically instead of by hand. ERP integration links your store to systems like SAP, NetSuite, and Microsoft Dynamics for orders, inventory, and finance. CRM integration connects platforms like Salesforce and HubSpot to sync customers and orders. PIM integration keeps product data accurate across every channel.
We build directly against Shopify's APIs to create exactly the behavior you need. The Storefront API powers custom and headless shopping experiences. The Admin API manages products, orders, customers, and store configuration programmatically. We use GraphQL and REST where each fits best, and respect Shopify's rate limits so your integrations stay stable under load.
Shopify Plus unlocks development capabilities that standard Shopify does not. We build for Plus merchants who need advanced logic, B2B functionality, and architecture that holds up at high order volume.
If your Plus store still runs on Shopify Scripts, you are on a deprecated path. We migrate your Scripts logic to Shopify Functions, the supported replacement that runs faster and survives checkout upgrades. We rebuild your discount, shipping, and payment customizations as Functions, test them against real cart scenarios, and deploy them without disrupting live sales.
We develop B2B features and expansion stores on Shopify Plus. B2B development includes custom catalogs, customer-specific pricing, quote workflows, and account-based purchasing. Expansion stores let you run multiple markets and brands from one Plus organization, sharing logic where it helps and staying independent where it matters.
Tell us the feature, logic, or integration your store is missing and we will scope the build and the fastest path to ship it.
We build custom storefront features that standard Shopify cannot deliver, backed by flexible data models. Metaobjects and metafields let us create structured custom content types, so your store can hold the data your products actually need.
We build product configurators, advanced bundling, subscription logic, custom calculators, and rich content systems on top of these data models. Instead of bending your products to fit Shopify's defaults, we model your data the way your catalog works, then build the front-end and back-end features around it. This is how a store stops feeling like a template and starts feeling like your product.
We keep development structured and transparent. You always know what we are building, why, and what comes next.
We map your requirements, audit your current setup, and define exactly what to build. You get a clear scope, an architecture plan, and a fixed quote before any code is written.
We design the data models, API connections, and app structure. We decide what runs as an app, a Function, or an integration, so the solution is right from the foundation.
We build in stages, integrate with your systems, and test against real data. You see progress in a staging environment, not just a status update.
We test across scenarios and edge cases, deploy without disrupting live sales, and hand over documented code your team can maintain. We stay available after launch.
We work with brands that have outgrown what themes and apps can do on their own.
Established merchants needing functionality no app provides.
Needing advanced logic and B2B functionality at volume.
Choosing Hydrogen for speed and full design freedom.
Needing ERP, CRM, or PIM integration that runs automatically.
Migrating their checkout logic to Shopify Functions.
Coming from other systems and needing custom builds.
We are an official Shopify, İkas, İdeasoft, and T-Soft partner, so we build on ecommerce platforms with full knowledge of what each one can and cannot do. That partner-level platform depth means we know where Shopify's limits are and how to engineer past them cleanly.
We are also a digital marketing and ecommerce agency, so we build features that serve growth, not just function. You get one team that understands the code, the commerce, and the strategy behind both. We write clean, documented code, communicate clearly at every stage, and stay available after launch. Your build is engineered to last and to scale.
