As a leading UK Shopify integration agency, we specialise in connecting Shopify with the tools and platforms that power your wider business operations. From ERP and inventory management to payment gateways, CRMs, accounting software, and custom app integrations — we deliver seamless, scalable solutions tailored to your needs. Our process begins with a deep dive into your current systems, tech stack, and operational workflows to identify integration opportunities and technical requirements.
Whether you're migrating platforms, scaling operations, or looking to streamline data across systems, we scope each integration with precision — prioritising stability, security, and long-term growth. We don’t just plug things in — we craft custom, future-proof solutions. Our team works closely with your internal stakeholders and third-party vendors to design integrations that improve efficiency, enhance visibility, and unlock new capabilities across your ecommerce ecosystem.
We’re experts in integrating Shopify with leading ERP systems such as Microsoft Dynamics 365, Business Central, NetSuite, and Brightpearl. These platforms sit at the core of your ecommerce business operations, and connecting them effectively with Shopify is essential for accuracy, efficiency, and growth. Our team understands the complexity involved — from syncing inventory across multiple channels to ensuring orders, product data, and customer information flow seamlessly between systems. We ensure finance, fulfilment, and merchandising teams are all working from a single source of truth, helping businesses reduce errors, speed up processes, and make better decisions.
We work closely with your ERP provider, internal teams, and any third-party vendors to scope, build, and implement robust integrations that align with your specific workflows. Whether you need real-time data syncs, scheduled batch updates, or a bespoke architecture using middleware like Patchworks or direct APIs, we tailor each solution to suit your unique requirements. Our ERP integrations are built for reliability, scalability, and long-term flexibility — designed to grow with your business and adapt as your operations evolve.
Integrating Inventory Management & Accounting Systems
We help Shopify brands integrate essential third-party systems to create a more connected, accurate, and efficient ecommerce operation. For inventory management, platforms like Linnworks enable businesses to track stock levels across multiple sales channels, automate reordering, and prevent overselling. By integrating these systems with Shopify, we ensure real-time inventory updates, accurate product availability, and smoother fulfilment workflows — saving valuable time and reducing costly errors. These integrations are especially powerful for brands managing large product ranges, multi-location stock, or high order volumes.
On the accounting side, we connect platforms such as Xero and QuickBooks to provide finance teams with up-to-date sales data, automated reconciliation, and simplified VAT and tax reporting. This reduces manual data entry, improves financial accuracy, and helps you stay compliant as you scale. We also support payment provider integrations beyond Shopify Payments — whether you need to offer alternative payment methods or meet specific compliance requirements. By integrating inventory, finance, and payment systems into your Shopify store, we help brands unlock greater visibility, speed up operations, and build the infrastructure to support long-term ecommerce growth.
We integrate Shopify with the platforms that power your customer relationships, enabling a more personalised, data-driven marketing and support experience. From CRMs like HubSpot and Salesforce to email platforms like Klaviyo, we ensure your customer data flows seamlessly across systems. This means you can capture leads, segment audiences, trigger automated campaigns, and personalise communication based on real-time purchase behaviour — all with confidence that your data is accurate and in sync. These integrations allow marketing teams to deliver targeted, relevant content that drives conversions and boosts customer lifetime value.
Beyond marketing, we also connect Shopify to industry-leading customer service tools like Gorgias and Zendesk. By surfacing key customer and order data directly inside your support team's inbox, we help reduce ticket handling times, improve first-response accuracy, and empower your team to deliver faster, more helpful support. Whether you're focused on improving retention, scaling your support operation, or driving more value from your marketing stack, our CRM and customer experience integrations ensure that your tools — and your team — are working smarter together.
We help brands unlock deeper insights by integrating Shopify with advanced analytics and reporting tools that turn raw data into actionable strategy. Whether you're connecting to business intelligence platforms like Looker or Power BI, setting up granular tracking with Google Tag Manager, or configuring GA4 to reflect your ecommerce funnel, we ensure every event and conversion is tracked with precision. Our team works closely with clients to define KPIs, map data flows, and create tailored reporting setups that match your goals — from traffic and product performance to conversion rate and customer lifetime value.
Leveraging our in-depth Shopify expertise, we also build and implement custom Shopify Pixels to track behaviour across the entire user journey — from product views and add-to-carts to checkout steps and purchases. As the ecommerce landscape moves beyond third-party cookies, we support server-side tracking to enhance attribution accuracy and protect long-term reporting reliability. We also help brands integrate their Shopify data with internal or custom-built reporting systems, giving stakeholders real-time visibility into business performance across teams and channels. From forecasting to campaign optimisation, we ensure your analytics ecosystem is robust, reliable, and built for scale.
For e-commerce businesses looking to go beyond standard functionality, we build custom integration solutions with third-party Shopify apps — giving customers a truly tailored experience. Whether it’s enhancing search and merchandising with tools like Voyado, powering loyalty programs, surfacing user-generated reviews, or managing complex B2B subscription models, our developers work directly with APIs to customise the setup to your specific needs. This allows you to retain the benefits and stability of market-leading apps while aligning functionality with your web design, workflows, and customer experience goals. It’s ideal for brands managing multiple websites, operating in niche verticals, or needing to streamline email marketing, CRM, or resource delivery across different areas of the business.
These integrations help your company unlock new capabilities without the burden of unnecessary manual work or bloated systems. From improving UX to increasing automation, our work touches on key aspects like maintenance, scalability, and performance — all while making sure your team has the knowledge and support to manage long-term success. We often link custom setups with other platforms like newsletters, LinkedIn lead gen tools, and internal phone or support systems to bring everything into one connected ecosystem. Whether you have a number of questions, specific topics to tackle, or just want to explore the potential, we’ll build a solution that fits your goals and drives measurable success.
We integrate Shopify with leading shipping platforms and third-party logistics (3PL) providers to streamline fulfilment and deliver a smoother experience for both your team and your customers. From real-time shipping rates and label generation to automated tracking updates and returns management, we ensure every step of the logistics journey is connected and efficient. Whether you’re working with carriers directly or using multi-warehouse 3PL solutions, we tailor each integration to reflect your operational setup, product types, and service levels — so orders flow from checkout to doorstep without friction.
For growing ecommerce brands and B2B businesses managing complex supply chains, our custom integrations help reduce errors, save time, and improve visibility. We connect Shopify to platforms like ShipStation, Peoplevox, or bespoke 3PL systems via APIs or middleware, ensuring accurate order syncing, inventory updates, and shipping data exchange in real time. Our developers work closely with fulfilment partners and internal teams to build robust, scalable shipping integrations that adapt as your company expands — whether you're adding new warehouses, international delivery options, or advanced customer service touchpoints.
We support brands and retailers in building and managing multi-vendor marketplaces on Shopify by integrating third-party systems that streamline vendor onboarding, product management, and order routing. Whether you're creating a curated platform with a select group of partners or scaling a large marketplace with hundreds of sellers, we build custom integration solutions that make managing vendors simple and scalable. From syncing vendor catalogs and stock levels to automating commissions, payouts, and notifications, we help bring structure and automation to even the most complex setups.
Our developers integrate Shopify with popular multi-vendor marketplace apps and external systems — or create entirely bespoke platforms depending on your business goals. We ensure a smooth experience for vendors, customers, and your internal team by aligning backend operations with frontend UX. Whether it's integrating vendor support tools, custom dashboards, or routing fulfilment via multiple warehouses or dropshippers, we make sure your marketplace is efficient, user-friendly, and built to grow. For B2B and DTC companies alike, our marketplace integrations unlock new revenue streams and operational flexibility while maintaining a consistent brand experience across every touchpoint.
Expanding into international markets requires more than just currency conversion — it demands a fully integrated, localised experience across your entire ecommerce operation. We help brands integrate Shopify with tools and services that power international selling at scale. From multi-currency support and localised checkout experiences to tax and duty automation using platforms like Global-E or Swap Commerce, we ensure that your store is compliant, seamless, and optimised for global customers. Whether you're using Shopify Markets or creating region-specific storefronts, we tailor your integrations to handle language, currency, shipping, and compliance with ease.
Behind the scenes, we connect your business systems — such as ERPs, inventory management, and fulfilment networks — to function flawlessly across multiple countries and regions. This means syncing international stock, routing orders to the correct warehouse, and aligning reporting by market or channel. We also implement integrations for region-specific payment providers, customer service tools, and localisation platforms to ensure every customer, no matter their location, receives a frictionless experience. For growing ecommerce brands, our internationalisation integration services remove complexity and unlock the infrastructure needed to scale globally — with confidence and control.
Our Memberships retainer is designed for brands that want long-term, proactive support to evolve their Shopify integrations as their business grows. Whether you're rolling out new tools, expanding into new markets, or refining your operational stack, our team is on hand to scope, build, and maintain your integration roadmap. From ongoing sync improvements to new third-party connections, we act as your embedded technical partner — ensuring your Shopify ecosystem stays efficient, secure, and scalable. Our retainers include flexible hours that can be used for development, consultancy, troubleshooting, and optimisation.
Many of our clients use our Memberships to maintain complex integrations — such as ERP, CRM, or 3PL connections — with confidence that any changes in business systems, APIs, or app updates will be handled smoothly. We also monitor data flow and performance, provide regular technical audits, and proactively suggest improvements based on evolving business needs. Whether you're a fast-scaling startup or an established global brand, our Memberships give you the freedom to focus on growth while we handle the technical delivery and ongoing optimisation behind the scenes.
As an official Patchworks partner, we offer tailored Shopify integrations that help ecommerce businesses of all sizes connect their business systems in one place — quickly and effectively. Patchworks is a powerful iPaaS (integration platform as a service) that allows seamless data flow between applications like ERPs, CRMs, shipping providers, finance tools, and more. It’s built for productivity, ensuring orders, products, customer information, and inbox data move smoothly between systems. By leveraging Patchworks' features and our integration expertise, agencies and businesses alike benefit from faster setup times, reduced manual tasks, and scalable solutions that grow with your ecommerce business.
