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 needs of medium-to-large-scale B2C and B2B brands. They also demonstrate their ability to cater to diverse needs across multiple ecommerce platforms. By leveraging the advanced features of Shopify Plus, these agencies provide growth services that empower companies, increase sales, enhance customer experience and optimise business operations, with growth marketing as a key component of these offerings. These services help brands maximise their potential through advanced eCommerce solutions and custom Shopify enhancements.

Ecommerce web design & development

Ecommerce web design and development is a core service of any Shopify Plus agency. These services include creating visually captivating and user-friendly ecommerce websites with UX design elements to drive loyalty and growth. Shopify Plus agencies use their Shopify and Shopify Plus ecosystem experience to deliver great user experiences that ensure a seamless user experience, driving conversions and online sales.

In addition to web design and development, these services often include branding, such as creating brand identities and developing brand strategies as part of the services for clients.

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

Shopify web design services

• Shopify and Shopify Plus theme customisation: Although Shopify has many pre-built themes, customisation is often required to match a brand’s identity and functional requirements. This service involves modifying a theme’s code (Liquid, HTML, CSS, JavaScript) to improve its look and feel. Shopify theme customisation can range from simple design tweaks like colour and font changes to more advanced modifications like restructuring page layouts, integrating app functionality, or optimising mobile experience. The goal is to maintain brand consistency and usability without a custom-built theme.

Shopify web 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 a fully functional and reliable ecommerce store. It involves setting up 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 have a store that runs smoothly under regular traffic and scales with business by leveraging Shopify’s built-in scalability and app ecosystem.
• Shopify Plus development: This service takes full advantage of Shopify Plus’s exclusive features for high-volume merchants with complex requirements. 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 using Launchpad to schedule sales events and product launches. Higher API rate limits allow seamless integration with demanding systems, while special features like a dedicated B2B wholesale channel and multi-store management simplify operations. The goal is to provide a high-performance e-commerce experience that can handle high traffic, complex promotions, and advanced operational requirements.
• Custom Shopify app development: When existing Shopify apps don’t meet specific business needs, custom app development provides a custom solution. This involves designing, building and deploying applications that integrate seamlessly with Shopify. Examples include developing unique product configurators, implementing special loyalty programs, integrating internal systems or enhancing customer-facing features for a competitive edge.
• Shopify API integration: This service connects Shopify or Shopify Plus stores to backend systems using Shopify’s APIs to enable data exchange and automation. Typical integrations include syncing customer data with CRM (Salesforce, HubSpot), automating order fulfilment via OMS (Order Management Systems), centralising product data using PIM (Product Information Management) systems, and integrating ERP (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 across multiple platforms.

Ecommerce platform migration services

• Shopify migration services: Migrating from another ecommerce platform (Magento, WooCommerce, BigCommerce or a custom solution) to Shopify requires careful execution. Shopify partners ensure a seamless transition by transferring essential data – 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 extensive testing before and after migration to ensure a smooth switchover.

Conversion Rate Optimisation Services

• Shopify store optimisation: Optimising a Shopify store involves speeding up 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 for a better user experience and SEO rankings. Search engine optimisation (SEO) ensures greater visibility by implementing technical best practices like structured data, sitemaps and robots.txt and on-page enhancements like meta titles, keywords, internal linking and mobile responsiveness to drive organic traffic. Optimising search engines is crucial to improving your online store’s visibility and attracting more organic traffic, leading to higher sales and better customer engagement. Conversion rate optimisation (CRO) enhances user engagement by analysing behaviour and making data-driven changes to store layout, navigation, product pages and checkout process to increase purchase completion rates.

How to choose the right ecommerce agency

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

• Portfolio and case studies: Don’t just be impressed by the big client logos on their website. Look beyond the surface level and understand the business challenges they’ve tackled and the solutions implemented. Ask detailed questions about the work done for those clients. Verify their past projects are relevant to your industry, company size and unique needs. Request client references and speak to past customers to get honest feedback and understand the Shopify agency’s project process.
• Services offered: Shopify Plus agencies have diverse skills. However, verifying they offer the services you need is crucial as needs often go beyond basic theme configuration. Confirm they are proficient 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. Also, assess their strategic capabilities in 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 surprises by asking for transparent pricing. Understand the ecommerce agency’s pricing structure, fixed project fees, monthly retainers or hourly rates. Carefully review detailed proposals to ensure they specify scope, deliverables, timelines and itemised costs, and what’s included and what’s extra. When comparing agencies, please focus on the value and ROI they bring rather than the price. Also, clarify how the budget will be managed for scope changes or unexpected issues.
• Communication & Support: Choose an agency known for being responsive, communicative and providing ongoing support. Clarify their communication plan upfront: who will be your main point of contact, how often will you be updated, what tools they use (Slack or project management software), and how they incorporate feedback. Understand their post-launch support framework: maintenance retainers, bug fixes, future Shopify development, and any Service Level Agreements (SLAs) for response times. Validate their claims by speaking to past clients.
• Technology stack: Since complex ecommerce involves many integrations and customisations, expertise in Shopify is paramount for a Shopify Plus development agency. Evaluate their skills across a broader technology stack. Assess their team’s capabilities in frontend development, backend programming (for custom apps or middleware), API integration strategies (REST, GraphQL, etc.), and experience with key platforms in your ecosystem (ERPs like NetSuite, CRMs like Salesforce, marketing tools like Klaviyo). This broad technical skillset allows a Shopify development agency to manage complex projects, troubleshoot issues, provide forward-looking solutions and understand your overall technology environment.
