WHY XOVAK

Why Brands Choose Us as Their Shopify Plus Agency

At Shopify Plus scale, the storefront is only one part of the commerce stack. Product and inventory data may live in an ERP, PIM or WMS. Orders may move through an OMS or 3PL. B2B buyers can require company accounts, customer-specific catalogues, pricing and payment terms. And during a replatform, URLs, customer data, analytics, integrations and organic visibility all need to survive the move.

Xovak brings those dependencies into one Shopify Plus delivery plan. Our team maps systems and data ownership before development, defines migration and integration requirements early, and connects storefront engineering, B2B, checkout, QA, performance and post-launch support under clear technical ownership.

The result is a Shopify Plus implementation designed around how your ecommerce operation actually works, not a collection of disconnected apps, integrations and storefront features.

Migrate from Magento, WooCommerce, BigCommerce, Wix or a custom ecommerce platform to Shopify Plus while preserving product, customer, order and SEO data and reconnecting ERP, CRM, PIM and fulfilment systems.

Shopify Plus Migration Without Sacrificing Search Visibility

A migration can improve the commerce platform while damaging organic performance if URL equity, metadata, internal linking and content are treated as last-minute tasks. Our Shopify Plus migration process incorporates search continuity from discovery onwards.

Before launch, we identify important indexed URLs, map legacy destinations, build and validate redirect rules, preserve valuable content and metadata where appropriate, review canonical behaviour and structured data, and test critical internal links.

After launch, the team monitors the new environment for redirect errors, missing content, indexation issues, performance regressions and integration failures.

The objective is straightforward: change the ecommerce platform without unnecessarily changing the signals customers and search engines already rely on.

Shopify Plus Development Services

Shopify Plus projects become difficult when the storefront is only one part of the system. Products may originate in a PIM. Inventory may come from an ERP or WMS. Orders may move through an OMS or 3PL. B2B customers may require company accounts, catalogs, payment terms and custom pricing. Marketing teams still need a storefront they can update without waiting for developers. XOVAK as a trusted Shopify Plus agency brings those requirements together into one Shopify Plus delivery plan.

Shopify Plus Design & Development

We design and engineer Shopify Plus storefronts around the needs of the teams who will run them. That means reusable sections, clean theme architecture, maintainable components and thoughtful merchandising controls not a storefront that requires a developer every time marketing wants to launch a campaign. Our work can cover UX strategy, UI design, theme engineering, custom functionality, analytics implementation, accessibility considerations, QA and release management.

Shopify Plus Migration & Replatforming

A migration is not simply a product import. For established brands, the real risk lies in the dependencies: customer history, orders, subscriptions, URLs, redirects, analytics, apps, search visibility, payment workflows, fulfilment and the systems surrounding the ecommerce platform. Xovak plans those dependencies before launch.We support migrations from Magento and Adobe Commerce, BigCommerce, WooCommerce and custom ecommerce environments, including data mapping, URL/redirect planning, integrations, validation, QA, cutover and post-launch monitoring.

Shopify B2B & Wholesale

We help brands use Shopify Plus to support wholesale requirements without unnecessarily separating B2B and DTC operations. Depending on your commercial model, that can include company accounts, catalogues, customer-specific pricing, payment terms, purchasing permissions and integrations with the systems that already own your customer, product and inventory data. Before development begins, we map the operating model so B2B features support your actual sales processes rather than forcing your team into a generic workflow. Shopify itself positions Plus around online, retail and B2B growth, including wholesale capabilities and platform extensibility.

Checkout Extensibility & Shopify Functions

Checkout should be treated as a revenue-critical system, not a collection of scripts. Xovak implements modern Shopify checkout customisation using the capabilities appropriate to Shopify Plus, including Checkout Extensibility and Shopify Functions where business logic requires them. Projects can include checkout UX, validation, promotions, delivery/payment logic, extensions, analytics and migration away from legacy customisation approaches. Shopify's current documentation confirms that advanced checkout customisation capabilities are available on Shopify Plus, including eligible app extensions in information, shipping and payment steps and access to the Checkout Branding API.

ERP, CRM, PIM, OMS & WMS Integrations

Enterprise ecommerce fails when critical systems disagree about products, inventory, customers or orders.We begin by defining each system of record, data ownership, sync direction, error handling and fallback behaviour. We then design and test the integration architecture before launch. Our integration work can cover: ERP and finance systems, CRM platforms, PIM systems, OMS and fulfilment systems, WMS and 3PL workflows, Subscription platforms, Search and merchandising.

Performance, CRO & Continuous Optimisation

Performance is not a one-time speed score. We examine frontend architecture, scripts, apps, images, Liquid/theme behaviour, analytics and customer journeys to identify technical and conversion friction. That work can include Core Web Vitals improvements, frontend performance, UX analysis, analytics implementation, A/B testing support, merchandising improvements, checkout optimisation and ongoing CRO engineering.

How to Choose the Right Shopify Plus Agency

A polished portfolio is useful, but it should not decide who gets responsibility for a revenue-critical ecommerce platform. When comparing Shopify Plus agencies, look for evidence that the team has solved problems similar to yours and that the people selling the project have the technical depth and delivery process to carry it through launch. We recommend evaluating every agency, including Xovak, against the same criteria.

Proven Shopify Plus work, not only logos

Ask for relevant projects and what the agency actually delivered: migration, B2B, checkout, custom development, integrations, performance or ongoing optimisation. Where confidentiality allows, look for named brands, live stores and measurable outcomes rather than a logo wall with no project context.
Icon

Technical depth that matches your commerce stack

A Shopify Plus agency should understand more than theme development when your project involves enterprise operations. Ask how the team approaches Shopify Functions, Checkout Extensibility, B2B, custom apps, APIs, ERP/PIM/OMS integrations, multi-market architecture and headless commerce, but only where those capabilities are relevant to your requirements.
Icon

A migration plan that protects more than product data

For a replatform, ask what happens to customers, orders, subscriptions, analytics, integrations, content and organic landing pages, not only products. Redirect mapping, data validation, launch QA and post-launch monitoring should be part of the migration plan before development begins.
Icon

The people who scope the work should understand how it gets built

Ask who will own architecture, development, QA and communication after the contract is signed. The important question is not the size of the agency; it is whether responsibilities are clear and whether the team making early technical decisions remains accountable for the consequences of those decisions.
Icon

Clear scope, cost and change control

A strong proposal should explain what is included, what is not, what assumptions the estimate depends on and how changes are handled. For integration-heavy or migration projects, unclear dependencies are often more dangerous than a higher initial estimate.
Icon

A plan for the store after launch

Shopify Plus work does not end when DNS changes. Ask who owns stabilisation, monitoring, performance improvements, conversion work, platform changes and the next development roadmap after launch.

How We Work

We begin by understanding how your ecommerce operations actually work. This includes your product structure, customer flows, fulfillment rules, and the systems that hold your key data such as ERP, CRM, IMS, and PIM. We identify your system of record for products, orders, customers, and inventory so the Shopify Plus build behaves predictably.

Outcome: a clear scope, mapped data flows, early risk controls, and measurable performance baselines.

Using the discovery insights, we architect the full Shopify Plus implementation. Your research is clear that successful enterprise builds depend on getting the integration map and data direction right first.

Here we define how data moves between Shopify Plus and your ERP, CRM, OMS, and PIM systems, along with precedence rules for conflicts, fallback behavior for failures, performance acceptance criteria aligned with Core Web Vitals, and a delivery roadmap with milestones and sequencing.

Outcome: a stable, low-risk architecture that prevents scope creep, sync failures, and performance regressions.

Design is built around enterprise UX and measurable performance. We structure page flows, merchandising layouts, mobile-first interactions, and B2B and B2C journeys so that the storefront remains fast, clear, and conversion-ready.

We ensure designs are compatible with the technical constraints defined in the strategy phase, especially speed budgets and component-level performance.

Outcome: a conversion-focused Shopify Plus UX that supports scale and meets performance targets.

Development covers theme engineering, Shopify Functions, custom apps, API work, and the integration logic that connects Shopify Plus with your internal systems.

The real complexity is the integrations rather than the front end, so we build the data pipelines first and validate them throughout development.

We implement custom Shopify Plus theme or headless architecture, ERP, CRM, IMS, and PIM integrations with verified data mapping, automated syncs with defined triggers and fallback logic, QA environments with rollback checkpoints, and continuous performance validation including LCP, INP, and CLS.

Outcome: a Shopify Plus implementation that remains fast, stable, and operationally reliable at scale.

Before launch, we validate everything including functionality, integrations, data accuracy, SEO mappings, and purchase paths.

We test integration stability and sync reliability, performance across devices, redirect mappings for safe migration, checkout and payment flows, and real-world operational scenarios involving inventory, pricing, and customer states.

Outcome: a fully validated, migration-safe, performance-ready Shopify Plus storefront.

Launch follows a controlled rollout with active monitoring. We track real-user performance, integration logs, and transactional flows and resolve any edge cases during the stabilization window.

After launch, we continue supporting your team with monitoring, performance checks, minor fixes, and ongoing operational guidance to ensure the storefront stays stable and efficient as traffic grows.

Outcome: a predictable go live, stable operations, and reliable post-launch support that keeps your Shopify Plus environment running smoothly.

Shopify Plus Agency FAQs

Straight answers for U.S. enterprise and high-growth brands evaluating Shopify Plus development, migration, B2B, integrations, checkout, performance, and ongoing support.

Shopify Plus is Shopify’s enterprise e-commerce platform, designed for high-growth brands (businesses typically >$1M+ annual sales). It includes advanced features like fully extensible checkout, B2B (wholesale) tools, international markets, automation (Shopify Flow), higher API limits, and multi-store management. Major brands such as Gymshark, Kylie Cosmetics, and Allbirds use Shopify Plus for the scalability and control it provides.

A Shopify Plus agency is a digital agency or development firm specialising in Shopify’s enterprise-tier platform. In other words, it focuses on larger e-commerce businesses that need Shopify Plus’s advanced capabilities. Such agencies design, build, migrate, and manage enterprise-grade stores on Shopify Plus. They typically have certified Shopify Plus experts and provide services beyond basic shop setup – custom app development, B2B/omnichannel integrations, headless commerce, and ongoing optimisation. Compared to a standard Shopify agency, a Plus agency works on high-volume, complex projects (big catalogs, global markets, deep ERP/OMS integration). In essence, a Shopify Plus agency helps companies unlock the full power of Shopify Plus, providing the expertise and support that enterprise merchants require.

A Shopify Plus agency plans and delivers the technical and commercial work required to build, migrate, integrate, optimize, and support enterprise ecommerce on Shopify Plus. Xovak’s Shopify Plus services include discovery, solution architecture, UX and theme engineering, data migration, B2B implementation, Checkout Extensibility, Shopify Functions, ERP and CRM integrations, performance optimization, conversion rate optimization, quality assurance, launch support, and ongoing development. The goal is to make the storefront, checkout, data, and operational systems work together as one reliable commerce ecosystem.

Partnering with a Plus agency helps your business unlock Shopify Plus’s full power. Because they focus only on high-end builds, they understand how to maintain fast page loads and 10K+ checkout events per minute. They ensure your site can handle flash sales and international growth. They also reduce risk: these agencies have gone through Shopify’s vetting (often holding advanced partner tiers). For example, Shopify’s own partner program (service track) has five tiers (Registered, Select, Plus, Premier, Platinum). A “Plus” partner has demonstrated success with complex, enterprise-level clients. Top agencies often reach Premier/Platinum status – a badge of Shopify trust. In fact, Shopify reserves its highest tier (Platinum) “for agencies with proven enterprise expertise”. This means the team working on your store can deep-dive into your business (marketing, supply chain, tech stack) rather than just tweaking themes. The result is a solution built for scale, uptime, and long-term growth.

Shopify Plus projects involve platform-specific architecture, commerce operations, checkout constraints, APIs, B2B requirements and migration risks. A team with substantial Shopify Plus experience can identify those issues earlier while designing the storefront around the way the platform actually works.

Xovak combines that Shopify expertise with a broader in-house engineering team for projects where commerce must connect to custom software or enterprise systems.

For brands selling in the United States, clear communication, business-hour availability, and accountable delivery matter as much as technical ability.

Xovak supports U.S. ecommerce teams with business-hour overlap, fluent communication, defined delivery phases, and an in-house development team covering Shopify Plus migrations, custom development, integrations, performance, CRO, and ongoing support.

We can work directly with your ecommerce team or alongside internal developers and agency partners, with project scope, dependencies, risks, and responsibilities documented from the beginning.

A brand should evaluate Shopify Plus when growth creates operational or technical complexity that its current setup can no longer handle cleanly.

Common signs include managing B2B and DTC commerce together, needing more advanced checkout customization, connecting ERP or fulfillment systems, operating multiple markets or storefronts, introducing custom automation, or relying on fragile apps and manual workarounds.

The decision should be based on your operating requirements, total cost of ownership, and growth plans not revenue alone.

Shopify Plus development costs vary widely – there is no one-size-fits-all price. Costs depend on project scope, features, integrations, and complexity. A simple theme customization or migration may be modest, while enterprise-level work (multi-store, headless, complex ERP) can run into the hundreds of thousands. Xovak Studio offers tiered packages to suit different needs, for example Focused Plus engineering starts at $2999, custom builds/redesigns typically range $8,000–$12,000, complex migrations/integrations start around $5,000, and ongoing support plans start at $999/month.

A focused Shopify Plus improvement may take a few weeks, while a complete custom build or enterprise replatforming normally requires several months.

The timeline depends on design requirements, data volume, integrations, custom functionality, B2B workflows, checkout requirements, number of markets, and stakeholder availability.

Xovak plans the project across discovery, architecture, design, development, data migration, integration testing, user acceptance testing, launch, and stabilization. A project-specific timeline is confirmed after the key systems and dependencies have been mapped.

Xovak supports Shopify Plus migrations from Magento Open Source and Adobe Commerce, BigCommerce, WooCommerce, Prestashop, Volusion  and custom ecommerce platforms.

Depending on the project, migration scope can include products, variants, collections, customers, order history, content, media, subscriptions, customer accounts, metadata, apps, analytics, integrations, and URLs.

We also plan theme development, checkout configuration, data validation, redirect implementation, quality assurance, launch sequencing, and post-launch monitoring. Before development begins, we identify what should be migrated, rebuilt, replaced with native Shopify functionality, or retired.

No agency can honestly guarantee that rankings will never fluctuate during a replatforming project. However, careful planning can significantly reduce avoidable SEO risk.

Xovak inventories important organic landing pages, maps old URLs to the most relevant new destinations, implements page-to-page 301 redirects, preserves essential content and metadata, and reviews canonicals, internal links, structured data, sitemaps, analytics, and search tracking.

Redirects and priority customer journeys are tested before launch, followed by post-launch monitoring of crawl errors, indexation, organic traffic, rankings, and conversions.

Yes. Shopify can support retail and wholesale customers through a blended ecommerce setup or through separate B2B and DTC storefronts.

Capabilities can include company accounts, customer-specific catalogs, pricing, quantity rules, volume pricing, payment terms, purchase order numbers, tax settings, and tailored checkout experiences.

Xovak first maps your buyers, catalogs, pricing, inventory, payment, approval, and fulfillment workflows. We then recommend whether a blended store, dedicated B2B store, or multi-store model provides the cleanest long-term operation.

Shopify Plus can connect with ERP, CRM, PIM, OMS, WMS, 3PL, subscription, loyalty, tax, payment, customer service, analytics, and business intelligence systems through supported apps, middleware, or custom APIs.

Xovak begins by defining which platform owns products, inventory, customers, orders, pricing, and fulfillment data. We then design synchronization rules, event flows, validation, logging, failure handling, and recovery processes.

This helps prevent duplicated business logic and makes the integration easier to monitor and support after launch.

Yes. Xovak uses Checkout Extensibility, checkout UI extensions, and Shopify Functions to create upgrade-safe checkout experiences and custom backend commerce rules.

Depending on the business requirement, this can include custom fields, conditional messaging, upsells, discount logic, delivery rules, payment rules, cart validation, checkout validation, analytics tracking, and post-purchase experiences.

We only introduce custom checkout logic when it solves a clear customer, revenue, compliance, or operational requirement.

Yes, but performance and conversion should be measured separately rather than treated as interchangeable promises.

Xovak audits theme code, apps, scripts, media, third-party tags, templates, mobile usability, merchandising, product pages, cart, checkout, and critical customer journeys. We establish performance and conversion baselines before prioritizing improvements.

The work can include Core Web Vitals optimization, mobile UX improvements, navigation and search, product-page clarity, cart friction reduction, checkout optimization, analytics validation, and structured experimentation.

Not always.

Headless commerce can be valuable when a brand has a genuine need for a highly customized frontend, multiple digital experience channels, composable architecture, or development requirements that a traditional Shopify theme cannot serve efficiently.

For many merchants, a well-engineered Shopify Plus theme provides a faster launch, simpler merchandising, lower maintenance, and a stronger return on investment.

Xovak recommends headless architecture only when the expected business and customer benefits justify the additional cost and technical complexity.

Yes. Xovak Studio can take over an existing Shopify Plus storefront, whether it was built internally or by another agency.

We can audit the theme, applications, checkout customizations, integrations, analytics, performance, accessibility, and release process; stabilize urgent issues; and create a prioritized improvement roadmap.

Support can include feature development, bug fixes, performance optimization, CRO, integration maintenance, quality assurance, release management, and ongoing technical support through a defined project, retainer, or dedicated development model.
