How to Choose a Shopify Plus Agency or Partner
On this page
Choosing a partner for Shopify Plus work is a higher-stakes version of choosing any Shopify agency, because Plus projects are enterprise-level — bigger, more complex, more expensive, and with more riding on getting them right. The general principles of choosing a Shopify agency (which I covered separately — process, the questions that reveal things, communication, references, watching how they handle money and scope) all still apply, but Plus adds specific considerations: you need genuine Plus expertise (not just general Shopify), experience with your type of Plus project, enterprise-level capability to handle the scale and stakes, and the depth to deliver and support a significant project. Choosing the wrong partner for a standard build is a setback; choosing the wrong partner for an enterprise Plus project — a migration, a complex B2B build, a major implementation — can be a costly, high-stakes failure.
This piece covers the Plus-specific considerations on top of the general agency-selection principles — genuine Plus expertise, the right Plus experience, enterprise capability, team depth, and the higher stakes — so you choose a partner equipped for the enterprise-level Plus work you need. Because at Plus scale, the partner choice matters even more than for a standard build, given the size, complexity, and stakes of the projects. Let me walk through the Plus-specific factors. (The general principles from the agency-selection discussion apply throughout — this adds the Plus layer.)
Genuine Plus expertise, not just general Shopify
The first and most important Plus-specific consideration: genuine Shopify Plus expertise, not just general Shopify experience. Plus involves capabilities that standard Shopify doesn’t — Checkout Extensibility, Shopify Functions, native B2B, the enterprise features (as the various Plus discussions cover) — and working with these well requires specific Plus expertise, not just general Shopify skill. An agency that does standard Shopify work isn’t necessarily equipped for Plus’s enterprise capabilities; you need genuine experience with the Plus-specific features and the enterprise-level work they involve.
So a key thing to assess is whether the agency has genuine Plus expertise — real experience with Checkout Extensibility, Functions, B2B, and the enterprise capabilities, not just general Shopify work with a claim of Plus capability. This matters because Plus work done by someone without genuine Plus expertise (treating it like a standard build, lacking experience with the enterprise capabilities) risks a poor outcome on a high-stakes project. So look for demonstrable, genuine Plus expertise — experience with the specific Plus capabilities your project needs (Checkout Extensibility if you need checkout customization, Functions if you need custom logic, B2B if you need wholesale, etc.) — rather than accepting general Shopify experience as sufficient for Plus work. The Plus-specific expertise is the foundation, since Plus’s enterprise capabilities require it, and a partner without genuine Plus experience isn’t equipped for the enterprise-level work, however good they are at standard Shopify. So assess genuine Plus expertise as the first Plus-specific criterion — real experience with the Plus capabilities, not just a claim of Plus capability atop general Shopify work.
Shopify Plus Partner status and the right experience
A relevant signal is Shopify Plus Partner status — the formal designation Shopify gives agencies in its Plus Partner program. This is a signal of Plus focus and capability (an agency in the Plus Partner program is invested in and recognized for Plus work), worth considering — but it’s a signal, not the whole story, so weigh it alongside the agency’s actual demonstrated Plus expertise and experience rather than treating the designation alone as sufficient. So consider Plus Partner status as a positive signal, while still assessing the agency’s genuine, demonstrated Plus expertise and experience directly.
More important than the designation is experience with your specific type of Plus project. Plus projects vary — a Plus migration (like the Magento migration discussion), a complex B2B build, a checkout customization project, a headless build on Plus, a major implementation — and you want an agency with experience in the type of Plus project you need, not just general Plus work. An agency experienced in Plus B2B builds is well-suited to your B2B project; one experienced in Plus migrations is well-suited to your migration; experience with your specific project type means they’ve navigated its specific challenges before. So look for experience with your type of Plus project — relevant, demonstrated experience in the specific enterprise work you need — as a key criterion, since experience with comparable projects is a strong indicator they can deliver yours. So weigh Plus Partner status as a signal, but prioritize genuine, demonstrated Plus expertise and, especially, experience with your specific type of Plus project — the relevant experience that indicates they can navigate your project’s specific challenges. The right experience (genuine Plus expertise, comparable project experience) matters more than the designation alone.
Enterprise capability and team depth
Plus projects are enterprise-level — bigger, more complex, higher-stakes than standard builds — so the agency needs enterprise-level capability: the ability to handle the scale, complexity, and stakes of Plus work, including managing a significant project, the technical complexity of enterprise capabilities, and the higher stakes (more riding on it, less room for failure). An agency equipped for standard builds isn’t necessarily equipped for enterprise-level Plus projects, which demand more capability, process, and capacity. So assess whether the agency has the enterprise-level capability to handle your Plus project’s scale, complexity, and stakes.
Team depth matters more at Plus scale, too. A standard build might be handled by a small team or even effectively one developer (with the single-point-of-failure risk noted in the general agency discussion), but Plus projects, being bigger and more complex, generally need more team depth — multiple capable people, redundancy, the capacity to handle a significant project and support it ongoing. So assess the agency’s team depth and capacity — can they bring the team a significant Plus project needs, with redundancy and the capacity to deliver and support it, rather than depending on a single person? At Plus scale, team depth and capacity are more important (the projects are bigger, the stakes higher, so the single-point-of-failure and capacity risks matter more). So evaluate enterprise capability (handling the scale, complexity, stakes) and team depth (the capacity and redundancy for a significant project) as Plus-specific criteria — Plus projects demand more capability and depth than standard builds, so the partner needs to have them. An agency without the enterprise capability and team depth for a significant Plus project risks struggling with the scale and stakes, however good they might be at smaller work.
The higher stakes and the ongoing relationship
Two more Plus-specific considerations. The higher stakes: Plus projects are big investments (the cost of Plus work is substantial, as the Plus pricing discussion covers) on high-stakes initiatives (enterprise migrations, major implementations), so the cost of choosing the wrong partner is high — a failed or poor Plus project is a costly, damaging setback. This raises the importance of choosing well: the due diligence (assessing expertise, experience, capability, references) matters more at Plus scale because the stakes of getting it wrong are higher. So apply the general agency-selection diligence (process, questions, references, communication) rigorously, given the higher stakes — the cost of a wrong Plus partner justifies thorough evaluation.
The ongoing relationship: Plus work is often not a one-off but an ongoing relationship — the Plus store needs maintenance, evolution, and ongoing development (as the maintenance discussion covers, more so for a complex enterprise store), so you’re often choosing a long-term partner, not just for one project. This means assessing the agency as a potential long-term partner — their ability to support and evolve your Plus store ongoing, not just deliver one project — and valuing the relationship factors (communication, reliability, understanding your business) accordingly. So consider that you’re often choosing an ongoing Plus partner, and assess them as such — their capacity for the ongoing relationship (maintenance, evolution, support) a complex Plus store needs, not just one-project delivery. The combination of higher stakes (justifying thorough diligence) and the ongoing relationship (valuing a long-term partner) shapes the Plus partner choice: choose carefully (high stakes) a partner you can work with long-term (ongoing relationship), with the genuine Plus expertise, relevant experience, enterprise capability, and team depth the enterprise-level work requires.
Questions and red flags
Building on the general agency questions, some Plus-specific ones to ask: What’s your genuine Plus experience — specifically with the Plus capabilities my project needs (Checkout Extensibility, Functions, B2B, etc.)? Can you show me comparable Plus projects you’ve delivered (of my type — migration, B2B, etc.)? How do you handle the enterprise scale, complexity, and stakes of Plus work? What’s your team depth and capacity for a project like mine? And how do you handle the ongoing relationship (maintenance, support, evolution) a Plus store needs? Their answers reveal whether they have the genuine Plus expertise, relevant experience, enterprise capability, team depth, and ongoing-relationship capacity your Plus project needs.
Plus-specific red flags: claiming Plus expertise without demonstrable genuine Plus experience (general Shopify experience presented as Plus capability), no comparable Plus project experience (especially of your type), treating Plus like a standard build (not appreciating the enterprise scale, complexity, and stakes), insufficient team depth for a significant project (single-point-of-failure risk at enterprise scale), and the general red flags (no real process, poor communication, no real references) which matter more at Plus stakes. So watch for these Plus-specific red flags alongside the general ones, since at Plus scale and stakes, choosing a partner without genuine Plus expertise, comparable experience, enterprise capability, and team depth is a high-stakes mistake. The questions (revealing genuine Plus expertise, relevant experience, enterprise capability, team depth, ongoing-relationship capacity) and red flags (claimed-not-demonstrated Plus expertise, no comparable experience, treating Plus as standard, insufficient depth) help you assess whether a partner is equipped for your enterprise-level Plus project — which, given the stakes, is worth assessing thoroughly.
A worked example: the right and the wrong Plus partner
To see the stakes, picture a brand needing a complex Plus project — say, a migration to Plus with native B2B and checkout customization. They consider two agencies. Agency A does solid standard Shopify work and claims Plus capability, but on inspection has little genuine Plus experience — no comparable Plus migrations, limited experience with B2B and Checkout Extensibility, and a small team. They’d be learning the enterprise Plus capabilities on the brand’s high-stakes project. Agency B has genuine, demonstrated Plus expertise — comparable Plus migrations delivered, real experience with native B2B and Checkout Extensibility, enterprise capability, and team depth. They’ve navigated this type of project before.
Choosing Agency A (perhaps because they’re cheaper, or the brand didn’t dig into the Plus specifics) risks a costly, high-stakes failure: an agency learning Plus’s enterprise capabilities on a complex migration-plus-B2B-plus-checkout project may struggle with the scale, complexity, and stakes, producing a troubled or failed project — an expensive setback on a big investment. Choosing Agency B, with genuine Plus expertise and comparable experience, gives the project a partner equipped to navigate its enterprise complexity, far more likely to deliver successfully. The difference between the partners — genuine Plus expertise and comparable experience versus general Shopify with a Plus claim — is the difference between a project likely to succeed and one at real risk, on a high-stakes enterprise investment.
This captures why the Plus-specific diligence matters: the partner choice on an enterprise Plus project has high stakes, and choosing a partner without genuine Plus expertise, comparable experience, and enterprise capability (like Agency A) risks a costly failure, while choosing one equipped (like Agency B) gives the project the partner it needs. The worked example shows the consequence of the choice — a high-stakes enterprise project succeeding or struggling based on whether the partner had the Plus expertise, experience, and capability — and why assessing for genuine Plus expertise and comparable experience (not accepting a Plus claim atop general Shopify) is worth the diligence the stakes justify. At Plus scale, the right partner versus the wrong one is the difference between a successful enterprise project and a costly failure.
Why thorough diligence pays off at Plus scale
A closing point on why the thorough evaluation is worth it at Plus scale: the cost of the diligence (time spent assessing genuine Plus expertise, comparable experience, enterprise capability, team depth, references) is small next to the cost of a wrong partner on a high-stakes enterprise Plus project (a costly, damaging failure on a big investment). So the diligence pays off — investing the effort to choose a equipped Plus partner is cheap insurance against the expensive failure a wrong partner risks on enterprise work. This is the same logic as the broader theme that the unglamorous diligence (assessing process, expertise, references) is worth it because it dodges expensive mistakes — applied at Plus scale, where the stakes (and thus the cost of getting it wrong) are higher.
So apply the diligence thoroughly for a Plus partner choice, recognizing that the higher stakes of enterprise Plus work make the thorough evaluation more valuable, not less — the cost of assessing carefully is small next to the cost of a wrong partner on a big, high-stakes project. The brands that choose Plus partners well invest in the diligence (assessing genuine Plus expertise, comparable experience, enterprise capability, depth, references) and choose a equipped partner; the brands that choose poorly skip the diligence (accepting a Plus claim, not digging into the specifics) and risk the costly failure a wrong partner brings to enterprise work. So at Plus scale, do the thorough diligence — it’s worth it given the stakes, and it’s how you choose the equipped partner an enterprise Plus project needs rather than risking the expensive failure of a wrong one. The diligence pays off because the stakes are high, which is the core reason to choose a Plus partner carefully and thoroughly rather than casually.
The bottom line
Choosing a partner for Shopify Plus work is a higher-stakes version of choosing any Shopify agency, because Plus projects are enterprise-level — bigger, more complex, more expensive, with more riding on getting them right — so the general agency-selection principles (process, revealing questions, communication, references, watching money and scope) apply, with Plus-specific considerations on top. The Plus-specific factors: genuine Plus expertise (real experience with Checkout Extensibility, Functions, B2B, and the enterprise capabilities, not just general Shopify with a claim of Plus capability), which is the foundation; experience with your specific type of Plus project (migration, B2B, checkout customization, headless — relevant, demonstrated experience navigating your project’s challenges); Shopify Plus Partner status (a positive signal, but weigh it alongside demonstrated expertise, not as the whole story); enterprise-level capability (handling the scale, complexity, and stakes of Plus work); team depth (the capacity and redundancy a significant project needs, more important at Plus scale than for standard builds); and recognition that Plus is often an ongoing relationship (choosing a long-term partner who can maintain and evolve your store, not just deliver one project). The higher stakes — Plus projects are big investments on high-stakes initiatives, so a wrong partner is a costly failure — justify thorough diligence, applying the general selection rigor more carefully given what’s at risk. Ask the Plus-specific questions (genuine Plus experience, comparable projects, enterprise-handling, team depth, ongoing-relationship capacity) and watch the Plus-specific red flags (claimed-not-demonstrated expertise, no comparable experience, treating Plus as a standard build, insufficient depth). Choose a partner equipped for the enterprise-level Plus work — with the real Plus expertise, relevant experience, enterprise capability, and team depth it requires — because at Plus scale and stakes, the partner choice matters even more than for a standard build, and getting it right is worth the thorough evaluation the high stakes justify.
Frequently asked questions
How is choosing a Shopify Plus agency different from a regular Shopify agency?
The general principles (process, revealing questions, communication, references, watching money and scope) all apply, but Plus is higher-stakes (enterprise-level projects — bigger, more complex, more expensive) and adds specific considerations: genuine Plus expertise (not just general Shopify), experience with your type of Plus project, enterprise-level capability to handle the scale and stakes, team depth for a significant project, and recognition that Plus is often an ongoing relationship. The higher stakes of Plus work make choosing well even more important than for a standard build.
What is Shopify Plus Partner status and does it matter?
It’s the formal designation Shopify gives agencies in its Plus Partner program — a signal of Plus focus and capability worth considering. But it’s a signal, not the whole story: weigh it alongside the agency’s actual demonstrated Plus expertise and experience rather than treating the designation alone as sufficient. More important than the designation is genuine, demonstrated Plus expertise and experience with your specific type of Plus project, which indicate they can actually deliver your enterprise-level work.
What’s the most important thing in a Shopify Plus partner?
Genuine Plus expertise — real, demonstrable experience with the Plus capabilities your project needs (Checkout Extensibility, Functions, B2B, the enterprise features), not just general Shopify experience with a claim of Plus capability. Plus involves enterprise capabilities standard Shopify doesn’t, requiring specific expertise, so a partner without genuine Plus experience isn’t equipped for the work, however good at standard Shopify. Close behind: experience with your specific type of Plus project, enterprise capability, and team depth.
What are red flags when choosing a Shopify Plus agency?
Claiming Plus expertise without demonstrable genuine Plus experience (general Shopify presented as Plus capability), no comparable Plus project experience (especially of your type), treating Plus like a standard build (not appreciating the enterprise scale, complexity, and stakes), insufficient team depth for a significant project (single-point-of-failure risk at enterprise scale), and the general red flags (no real process, poor communication, no real references) — which matter more at Plus stakes. Given the high stakes of enterprise Plus work, these red flags signal a partner not equipped for your project.
