How to Choose a Shopify Plus Agency: The Complete 2026 Guide
.jpg)
Six months into a failed Shopify Plus build, a wholesale distributor found out their agency had completed only three Plus projects. All three were apparel brands running standard DTC checkout. The distributor needed ERP integration, customer-specific pricing, net payment terms, and a dealer portal. The agency learned what those requirements were at the same time the client did.
That is not a horror story. It is a repeatable pattern. The wrong agency is not always an incompetent agency. It is almost always an agency built for a different kind of project than yours.
This guide gives you the framework to avoid that outcome: what a Shopify Plus agency actually is, how the partner tier system works, when to hire an agency vs. a freelancer, ten questions to ask before you sign, a pricing reference, and a complete pre-hire checklist.
A Shopify Plus agency is a certified development and strategy partner authorized by Shopify to work on the Plus tier of the platform. These agencies have completed Shopify's vetting process, demonstrated a documented track record of enterprise-level projects, and agreed to Shopify's partner standards.
The work scope of a Shopify Plus agency includes:
Not every Shopify agency is a Shopify Plus agency. The certification, the project history, and the technical depth required for Plus-level work are meaningfully higher than standard Shopify development.
Before you talk to a single agency, understand the tier structure. The difference between partner levels is significant and directly affects the quality, support access, and track record you can expect.
The entry-level designation. Shopify Partner status is relatively accessible, and most agencies working on Shopify can claim it. It indicates a basic level of platform knowledge and access to partner resources. When an agency lists "Shopify Partner" on their website, that is a low bar and not a reliable signal of Plus-level capability.
Agencies with Plus Partner status have been vetted by Shopify specifically for enterprise-level work. Achieving Plus Partner status requires demonstrating a track record of successful Plus projects, meeting quality and revenue thresholds, and passing Shopify's partner review process. Plus Partners receive dedicated Shopify partner managers, early access to new platform features, and access to Shopify's enterprise partner knowledge network.
When evaluating an agency for a Shopify Plus project, Plus Partner status is the minimum viable credential to consider. Agencies without it should not be handling Plus work.
Platinum is the top tier of the entire Shopify Partners program globally. Platinum status reflects consistent high performance across a significant volume of Plus projects: build quality, measurable client outcomes, and GMV generated on the platform. Fewer than a few hundred agencies worldwide hold this designation.
Platinum Partner status is not awarded for tenure. It is earned by agencies that have delivered at scale, repeatedly, with verifiable outcomes. If you are managing a complex migration, a B2B wholesale operation, or an enterprise-grade DTC build, Platinum Partners represent the agencies with the most directly relevant track record.
Uncap is a Shopify Platinum Partner. You can verify any agency's current tier directly in Shopify's Partner Directory.

This is the first decision to make before you start evaluating partners, and the answer depends on your project complexity, not your budget.
A freelance Shopify Plus developer can be the right choice for a narrow, well-defined scope: a theme customization, a specific app integration with a clearly documented API, a single Shopify Function build. Freelancers can move fast and cost less for contained work.
The risk with freelancers on larger projects is capacity and continuity. A freelancer has no bench. When they are unavailable, your project stops. When something breaks after launch, you may have no guaranteed support path.
For any project that combines multiple disciplines, a full agency is the correct choice. Platform migrations, ERP integrations, B2B configuration, custom checkout logic, and multi-channel builds all require coordinated expertise across development, strategy, QA, and project management.
Agencies also provide continuity. A named team, an escalation path, a defined support structure, and a post-launch relationship are all standard in an agency engagement. They are rarely available from a single freelancer.

These are the questions that expose the difference between an agency built for your project and one that will figure it out at your expense.
Always confirm tier status directly in Shopify's Partner Directory rather than relying on an agency's own marketing materials. Ask for the number of Plus projects delivered, broken down by type: migrations, net-new builds, B2B configurations, and ongoing retainers. Ask how many of those projects are currently live and generating revenue.
Strong answer: A specific project count with context, and a direct link to their Partner Directory listing.
Red flag: "We've worked on many Plus projects" without a number, or an inability to provide a verifiable tier.
Portfolio relevance matters more than portfolio size. An agency with 200 DTC fashion builds does not have the experience base to handle a wholesale distributor with 3,000 SKUs, custom pricing tiers, and an ERP integration requirement. The technical decisions, data architecture, and order flow patterns are genuinely different.
Ask for case studies that match your business model, vertical, order complexity, and integration requirements. Ask what the nearest analogue is if they do not have an exact match, and ask specifically what lessons from that project apply to yours.
Strong answer: A named case study with business context, the technical problem solved, and a measurable outcome.
Red flag: A polished portfolio of visually uniform DTC brands with no mention of business challenges, integration work, or operational outcomes.
Agencies win business on their senior partners and deliver on their junior staff. That is a structural reality, not a criticism. The question is whether you know who the junior staff are before you sign.
Ask for names and seniority levels of the people assigned to your account. Ask explicitly whether the agency uses subcontractors or offshore development on Plus projects. Ask who your day-to-day point of contact is and whether they were involved in similar projects previously.
Strong answer: Named team members with roles, a direct answer to the subcontractor question, and a clear escalation path.
Red flag: "Our team" as the answer, or commitments to share team details only after the engagement begins.
Integration is where most Shopify Plus projects encounter their real complexity and their real cost overruns. The specific question is whether the agency builds integrations properly or applies off-the-shelf connectors that function under light load and fail under production conditions.
Ask specifically about the systems you use. If your ERP is NetSuite, ask how many NetSuite-Shopify Plus integrations they have built and what edge cases they encountered. If you use SAP, Microsoft Dynamics 365, Epicor, or QuickBooks, ask the same questions. Ask whether they build to real-time bidirectional sync or batch processing, and what their approach is to handling sync errors and data conflicts.
Strong answer: Named ERP experience, specific integration examples, a clear methodology for error handling and real-time sync architecture.
Red flag: "We can integrate with anything" without examples. Or relying entirely on third-party middleware without a custom integration option for complex requirements.
The agencies that deliver on time and on budget invest in discovery. They define scope, document requirements, map data flows, and force the hard decisions before development starts. The agencies that run over budget skip this step and charge for the consequences.
Ask what their discovery or strategy phase produces as a deliverable. Ask whether discovery is a separate paid engagement or part of the build contract. Ask how scope changes are handled once development is underway and what process exists for approving them.
Strong answer: A named, structured discovery phase with a clear deliverable, a policy on scope changes, and examples of how previous scope issues were handled.
Red flag: "We just get started" or "discovery is part of the build" without a defined output.
Fixed-price engagements and time-and-materials engagements each have legitimate trade-offs depending on project type. What matters is transparency: how the estimate was built, what assumptions are embedded in it, and what triggers a change order.
Ask for a line-item breakdown of how their estimate was built. Ask what assumptions about your data, integrations, and workflows are baked into that number. Ask what is explicitly excluded. Ask for a real example of a scope change in a previous project and how it was billed.
Strong answer: A line-item estimate with assumptions documented, an explicit exclusions list, and a candid scope-change example.
Red flag: A single number delivered without explanation, or a firm commitment to a price before the agency has asked you anything about your data, integrations, or requirements.
If your project involves moving from an existing platform, this question is critical. Migrations from Magento, Salesforce Commerce Cloud, BigCommerce, WooCommerce, or a custom-built platform to Shopify Plus carry genuine risks: corrupted customer data, lost order history, broken SEO equity, and a launch that disrupts revenue rather than accelerating it.
Ask specifically about migrations from your current platform. Ask how they handle data extraction and cleaning from legacy systems. Ask what their SEO migration protocol is for URL structure and 301 redirects. Ask whether they conduct load testing before go-live. Ask for a migration they have completed from a similar complexity level.
Strong answer: Named migration experience from your current platform, a documented SEO migration protocol, load testing as a standard step, and a migration case study with outcomes.
Red flag: No migrations from your current platform in their history, or vague assurances about SEO and data integrity without a defined process.
If you are a manufacturer, distributor, or wholesaler, this is the most important question on this list. B2B Shopify Plus is a distinct technical discipline from DTC Shopify Plus. The data architecture is different. Order flows arrive through sales reps, phone, and email rather than through a standard checkout. Pricing is account-specific and negotiated. Payment is on net terms, not immediate authorization. Account structures involve company hierarchies with multiple buyer contacts and approval workflows.
An agency that has built 50 DTC fashion stores has not built what a B2B wholesale operation requires. Ask directly: how many B2B Shopify Plus builds have they delivered? What did those projects involve specifically: dealer portals, customer-specific price lists, ERP-connected order management, draft order workflows, quote management, net payment terms? Can they show you a live B2B Plus store that resembles your operation?
Strong answer: A specific B2B project count, named B2B capabilities delivered, and at least one live reference in a comparable industry.
Red flag: Enthusiasm about B2B as an "exciting space" paired with zero B2B case studies.
Shopify Plus evolves faster than most enterprise platforms. Shopify Scripts reached end-of-life in June 2026. Custom checkout logic now runs through Shopify Functions, a WebAssembly-based framework that requires different technical skills than Scripts. Hydrogen and Oxygen are the current stack for headless storefronts. Shopify Flow handles automation. An agency that has not kept up with these changes is doing legacy work on current projects.
Ask whether the agency builds checkout customizations using Shopify Functions or Scripts. Ask whether they have deployed Hydrogen-based storefronts and what their opinion is on when headless architecture is and is not appropriate. Ask about their use of Shopify Flow for automation and what workflows they have built.
Strong answer: Confirmed Functions usage (not Scripts), clear opinions on when headless is and is not the right choice, and named Shopify Flow use cases.
Red flag: References to Shopify Scripts as a current capability, or a "headless is always better" position without nuance about cost and maintenance overhead.
Go-live is not the end of the project. Shopify Plus stores require ongoing updates, integration maintenance, performance monitoring, and optimization. The agency that built the store has the context to support it most efficiently. Handing off to a new agency post-launch is expensive and disruptive.
Ask what post-launch engagement looks like structurally. Ask whether they offer retainer agreements and what those include. Ask who your point of contact is after launch, whether it is the same person from the build, and what their response time commitment is for critical issues.
Strong answer: A defined support structure, named post-launch contact, a response time commitment for critical issues, and a clear retainer model.
Red flag: "We provide documentation and hand off" on a complex Plus build, especially one with custom integrations.
Some signals matter more than any positive impression.
They cannot tell you who runs your project. If the salesperson cannot name the project lead, the project will be staffed by whoever is available when it starts.
Their portfolio has no measurable outcomes. Screenshots are decoration. A case study that explains the business challenge, the approach, and a result you can evaluate is evidence of capability. The absence of outcomes usually means there are no outcomes worth reporting.
They lead with tools rather than your problem. An agency that opens with their tech stack before understanding your operation is a build shop, not a strategic partner. The conversation about tools comes after the conversation about your requirements.
Their timeline ignores your integration complexity. A Shopify Plus migration with a NetSuite integration, B2B pricing configuration, and custom order workflows is not a 60-day project. An agency that quotes it that way has not done it before.
They have not asked about your data. Your product catalog, customer records, pricing tiers, and historical orders are the substance of any Plus migration or B2B build. If no one has asked about them, the estimate is a guess.
They cannot explain how Shopify Functions differ from Shopify Scripts. Scripts reached end-of-life in June 2026. Any agency doing active Plus work knows this. Confusion on the question is a technical competency signal.
Agency pricing for Shopify Plus work varies significantly based on scope, complexity, and the agency's cost structure. These ranges reflect North American market rates in 2026.
Typical Price Range: $15,000 to $50,000
Notes: Standard Plus theme, limited custom development
Typical Price Range: $40,000 to $120,000
Notes: Custom design, standard integrations
Typical Price Range: $50,000 to $150,000
Notes: Depends on data complexity and SEO requirements
Typical Price Range: $75,000 to $200,000
Notes: Custom pricing, ERP sync, buyer portal
Typical Price Range: $150,000 to $500,000+
Notes: Hydrogen, multi-region, complex integrations
Typical Price Range: $5,000 to $20,000/month
Notes: Scope-dependent
These are ranges, not quotes. The number that applies to your project depends on your specific data architecture, integration requirements, catalog complexity, and the scope of custom development.
The only reliable way to get an accurate project cost is a scoped discovery process. Any agency giving you a confident fixed price before they understand your data, your integrations, and your business logic is estimating, not scoping.

What is a Shopify Plus agency?
A Shopify Plus agency is a certified digital partner authorized by Shopify to deliver enterprise-level work on the Shopify Plus platform. These agencies have completed Shopify's vetting process and hold Plus Partner or Platinum Partner status. Their work covers platform migrations, custom development, ERP and CRM integrations, B2B wholesale configuration, headless commerce architecture, and ongoing optimization. They are distinct from standard Shopify agencies in their certification level, technical depth, and track record on complex projects.
What does a Shopify agency do?
A Shopify Plus agency handles the full lifecycle of an enterprise Shopify Plus deployment: discovery and architecture planning, platform migration from legacy systems, custom storefront development, checkout logic via Shopify Functions, integration with ERP and PIM systems, B2B wholesale configuration, post-launch optimization, and ongoing retainer support. The scope of work depends on whether the engagement is a net-new build, a migration, a B2B implementation, or a combination.
What is the difference between a Shopify Plus Partner and a Shopify Platinum Partner?
Shopify Plus Partner is an enterprise-level certification requiring a demonstrated track record of successful Plus projects and passing Shopify's vetting process. Shopify Platinum Partner is the highest tier in the global program, reserved for agencies with consistently high volume, verified outcomes, and recognized expertise across the platform. Platinum status reflects active, proven performance rather than tenure. Both tiers have access to Shopify's partner support network, but Platinum Partners represent the top cohort globally.
How much does a Shopify Plus agency charge?
Shopify Plus agency project costs in North America range from $15,000 to $50,000 for straightforward theme migrations, $40,000 to $150,000 for standard platform migrations and new DTC builds, and $75,000 to $200,000 for B2B builds with ERP integration. Enterprise headless builds or multi-market projects can reach $500,000 or more. Monthly development retainers typically run $5,000 to $20,000 depending on scope. Any agency providing a firm price before scoping your data and integration requirements is estimating, not quoting.
Should I hire a Shopify Plus agency or a freelancer?
Use a freelancer for narrow, well-defined scopes: a specific theme change, a single app integration, a contained Function build. Use a Shopify Plus agency for any project combining multiple disciplines: migrations, ERP integrations, B2B wholesale builds, headless architecture, or projects where post-launch support is required. The decisive factor is not budget but complexity. Underpowering a complex project with a single freelancer is typically more expensive than hiring an agency from the start.
How long does a Shopify Plus project take?
A standard Shopify Plus migration or new build takes 12 to 20 weeks from kickoff to go-live. B2B builds with ERP integration typically run 16 to 24 weeks. Headless implementations or multi-market builds with complex data architecture can take six to twelve months. Timelines that sound faster than these ranges should be treated skeptically for anything beyond a simple theme migration.
What is Shopify Plus used for?
Shopify Plus is Shopify's enterprise commerce platform, designed for brands with high order volumes, complex integrations, multi-market operations, or advanced B2B requirements. It unlocks checkout extensibility via Shopify Functions, native B2B features including company accounts and price lists, multi-store management through Organization Admin, headless architecture via Hydrogen and Oxygen, and advanced automation via Shopify Flow. It is used by both DTC brands scaling beyond standard Shopify and B2B manufacturers and distributors replacing legacy ERP portals.
Is Shopify Plus worth it?
Shopify Plus is worth the investment when your operation outgrows standard Shopify's native capabilities: when you need checkout customization, B2B wholesale features, multi-market configuration, or ERP integration that standard plans cannot support. At $27,600 per year, it is substantially more cost-effective than legacy enterprise platforms like Magento or Salesforce Commerce Cloud, which carry significantly higher total cost of ownership in licensing, hosting, and development. The question is not whether Shopify Plus is worth it but whether your operation has reached the complexity threshold that justifies it.
How do I find a Shopify Plus agency?
Start with Shopify's Partner Directory. Filter by location, industry, and services to identify certified Plus Partners and Platinum Partners relevant to your project type. Shortlist three to five agencies, request case studies matching your business model, ask all ten questions in this guide, and check references from similar projects before making a decision.
What questions should I ask a Shopify Plus agency before hiring?
The ten most important questions are: (1) What is your partner tier? (2) Do you have work for a business like mine? (3) Who specifically will work on my project? (4) What ERP integrations have you built and for which systems? (5) What does your pre-development discovery process produce? (6) How do you price a project and handle scope changes? (7) What migration experience do you have from my current platform? (8) Do you have B2B Shopify Plus experience? (9) Do you use Shopify Functions for checkout logic? (10) What does your post-launch support structure look like? Each question is designed to expose real capability or the absence of it.
The best Shopify Plus agencies are not just build shops. They are partners who have shipped enough similar projects to know what breaks under production conditions, what integration patterns survive platform updates, and what your buyers need from the experience.
The framework above gives you the tools to tell the difference. Ask all ten questions. Verify tier status independently. Require case studies with outcomes. Know your project type, and match it to an agency with specific experience in that type.
For manufacturers, distributors, and wholesalers evaluating Shopify Plus for B2B operations, the question about B2B experience is not a polite interview question. It is the one that determines whether the agency can actually build what you need.
Uncap has been a Shopify Platinum Partner since 2013 with over 380 B2B commerce projects delivered for manufacturers, distributors, and wholesalers across North America. B2B is not a vertical we cover alongside DTC work. It is the only work we do.
