Services offered by Shopify Plus agencies

Shopify Plus partners offer many services to help brands succeed in the competitive ecommerce market. These services cater to the unique needs of medium-to-large-scale B2C and B2B brands. They also demonstrate their capability to cater to diverse needs across multiple ecommerce platforms. By leveraging the advanced features of Shopify Plus, these agencies provide tailored growth services that empower companies, increase sales, enhance customer experience, and optimise business operations.

Ecommerce web design & development

Ecommerce web design and development services are crucial to any Shopify agency’s offerings. These services include creating visually captivating and user-friendly ecommerce websites incorporating UX design elements to drive loyalty and growth. Shopify Plus agencies use their Shopify and Shopify Plus ecosystem experience to deliver outstanding user experiences that ensure a seamless user experience, driving conversions and online sales.

Some of the key ecommerce web design and development partner services offered by Shopify Plus partners include:

Custom Shopify web design services

• Shopify theme customisation: Although Shopify offers a variety of pre-built themes, customisation is often necessary to align with a brand’s identity and functional requirements. This service involves modifying a theme’s code (Liquid, HTML, CSS, JavaScript) to enhance its appearance and functionality. Shopify theme customisation can range from simple design tweaks, such as colour and font changes, to more advanced modifications, like restructuring page layouts, integrating app functionalities, or optimising the mobile experience. The goal is to improve brand consistency and usability without needing a custom-built theme.

Shopify website development services

Shopify Plus agencies also offer various development services, backed by their technical expertise, to help brands build and grow their ecommerce capabilities. These services include custom integrations and other development services to help companies develop and grow their ecommerce capabilities.

• Shopify development: This service maximises Shopify’s core features to build fully functional and reliable ecommerce stores. It involves establishing the store’s foundation, configuring essential settings (payments, shipping, taxes), and selecting and customising themes using the built-in editor. Additionally, it includes installing and configuring apps from the Shopify App Store to extend functionality. The goal is to create a store that runs smoothly under typical traffic conditions and scales with business by leveraging Shopify’s built-in scalability and app ecosystem.
• Shopify Plus development: Designed for high-volume merchants with complex needs, this service takes full advantage of Shopify Plus’s exclusive features. It includes implementing Shopify Functions to customise checkout logic (e.g., advanced discounts, shipping rules, payment options), using Shopify Flow to automate workflows (e.g., inventory alerts, customer segmentation, fraud detection), and leveraging Launchpad to schedule sales events and product launches. Higher API rate limits enable seamless integration with demanding systems, while specialised features like a dedicated B2B wholesale channel and multi-store management streamline operations. The objective is to create a high-performance e-commerce experience capable of handling significant traffic, complex promotions, and advanced operational requirements.
• Custom Shopify app development: When existing Shopify apps fail to meet specific business needs, custom app development provides a tailored solution. This involves designing, building, and deploying applications that seamlessly integrate with Shopify. Examples include developing unique product configurators, implementing specialised loyalty programs, integrating proprietary internal systems, or enhancing customer-facing features for a competitive edge.
• Shopify API integration: This service connects Shopify or Shopify Plus stores with essential backend systems using Shopify’s APIs to enable smooth data exchange and automation. Typical integrations include syncing customer data with CRM platforms (Salesforce, HubSpot), automating order fulfilment via OMS (Order Management Systems), centralising product data using PIM (Product Information Management) systems, and integrating ERP solutions (NetSuite, SAP) to manage finances, inventory, and operations. Effective API integration eliminates manual data entry, reduces errors, improves efficiency, and provides a unified view of business operations across multiple platforms.

Ecommerce Platform Migration Services

• Shopify migration services: Migrating from another e-commerce platform (Magento, WooCommerce, BigCommerce, or a custom solution) to Shopify requires careful execution. Shopify partners ensure a seamless transition by transferring essential data—including products, customer records, order history, content pages, and blog posts—while preserving data integrity and SEO value. The process includes setting up proper URL redirects, minimising downtime, and conducting extensive testing before and after migration to ensure a smooth switchover.

Conversion Rate Optimisation Services

• Shopify store optimisation: Optimising a Shopify store involves enhancing speed, discoverability, and conversion rates to improve overall performance. Speed optimisation reduces load times through image compression, code minification (CSS/JS), browser caching, script reduction, and theme code optimisation, leading to a better user experience and improved SEO rankings. Search engine optimisation (SEO) ensures greater visibility by implementing technical best practices such as structured data, sitemaps, and robots.txt, along with on-page enhancements like optimised meta titles, keywords, internal linking, and mobile responsiveness to drive organic traffic. Conversion rate optimisation (CRO) enhances user engagement by analysing behaviour and making data-driven refinements to store layout, navigation, product pages, and checkout process, ultimately increasing purchase completion rates.

How to Choose the Right Ecommerce Agency

Our experience in Shopify development is your gateway to online success. Consider these factors when selecting a Shopify Plus partner or a Shopify development agency:

• Portfolio and case studies: When evaluating an ecommerce agency, don't just be impressed by the prominent client logos on their website. Instead, look past surface-level aesthetics to understand the specific business challenges they've tackled and the strategic solutions implemented. Ask detailed questions about the work performed for those highlighted clients. Verify their past projects are relevant to your industry, company size, and unique needs. Finally, request client references and speak directly with past customers to get honest feedback and understand the Shopify agency's step-by-step project process.
• Services offered: Shopify Plus agencies possess diverse skills. However, verifying they provide the specific services you require is crucial, as needs often extend beyond basic theme configuration. Confirm their proficiency in core technical areas such as custom theme development from scratch, complex platform migrations (e.g., from Magento or WooCommerce), intricate API integrations with key operational systems (ERP, CRM, PIM), and custom app development. Additionally, assess their strategic capabilities in specialised e-commerce marketing (SEO, PPC, email), conversion rate optimisation (CRO), and international selling support. The ideal agency excels at technical implementation and partnering on your growth strategy.
• Pricing & Budget: Avoid financial misunderstandings by demanding clear, transparent pricing. Understand the ecommerce agency's charging structure, fixed project fees, monthly retainers, or hourly rates. Carefully examine detailed proposals, ensuring they fully specify the scope, deliverables, timelines, and itemised costs, distinguishing included work from potential extras. When comparing agencies, focus on the value and potential ROI they bring rather than just the price tag. It's also vital to clarify beforehand how budget adjustments for scope changes or unexpected issues will be managed.
• Communication & Support: Select an agency known for being responsive, communicative, and providing reliable ongoing support. Clarify their communication plan upfront: identify key contacts, agree on update frequency, understand preferred tools (like Slack or project management software), and learn their process for incorporating feedback. Gauge their responsiveness during initial inquiries, as this often predicts future interactions. Equally important is to thoroughly understand their post-launch support framework, including options for maintenance retainers, bug fixes, future development, and any Service Level Agreements (SLAs) that guarantee specific response times. Validate claims about their communication and support quality by speaking directly with client references.
• Technology stack: Since complex e-commerce often involves intricate integrations and customisations, a development agency's expertise must extend beyond Shopify Plus alone. Therefore, evaluate their proficiency across a broader technology stack. Assess their team's capabilities in essential areas like frontend development, backend programming (for custom apps or middleware), API integration strategies (using REST, GraphQL, etc.), and experience with key platforms within your ecosystem (such as ERPs like NetSuite, CRMs like Salesforce, or marketing tools like Klaviyo). This broad technical skillset enables a development agency to manage complex projects, effectively troubleshoot issues, provide forward-looking solutions, and understand your overall technological environment.
