The Ultimate Guide to the Best Tech Stack for Medusa JS
Who Is This Content For?
This guide is for founders, CTOs, CMOs, COOs, and any decision makers considering a switch from WooCommerce, Salesforce, or other legacy eCommerce platforms to Medusa.js, or even starting from scratch to build and power their store using Medusa.js.
This is not generic cookie cutter content written by someone who has never written a line of code. It is written by someone who understands both business and tech, with hands-on experience working with Medusa.js.
We will break down what tech stack works best with Medusa, what ROI you can expect, key costs, what to avoid, and more. This guide will also cover tools across different departments such as marketing, content, analytics, logistics, and help you decide if Medusa.js is the right fit for your business or not.
Why should u listen to us?
Quick background: I’ve been building modern web products for years.
We live and breathe composable solutions tailored specifically for eCommerce brands.

We’re not just another agency experimenting with headless commerce
We have fully pivoted from platforms like Shopify and other legacy stacks to Medusa.js because we believe in its flexibility, performance, and developer-first architecture.
Over the past few years, we have built and launched B2B, B2C, and DTC stores using Medusa.js — from small startups to large enterprise clients with complex needs. Our entire approach is shaped by real-world experience implementing Medusa.js in production across different industries and business models.
We are not tied to any single vendor or hype-driven tool. What matters to us is choosing the right stack for your business, one that aligns with your growth goals, internal team capacity, and customer journey.
That is what truly sets us apart. When it comes to headless commerce with Medusa.js, we know exactly what we are doing, and we are here to help you do it right.
So when it comes to talking about the guide on Medusa.js, over the years we have tried, failed, and perfected using different combinations from headless CMS, PIM, ERP, and more platforms. I am going to talk only about tools which you, as a business, should adapt to your business when choosing Medusa, not you having to adapt to the platforms you pick.
So, no wasting more time, let's break down all the important pillars of building an ecommerce solution:
The best part about building a composable solution is flexibility. If you ever feel the need to switch tools, you should be able to do so easily.
However, there are a few core pillars that should be carefully chosen from the start and ideally not replaced later. These include your Headless CMS and PIM, as they are deeply integrated and impact multiple parts of your business. Plan and decide on these with a long-term vision.
So, let's start with Headless CMS.
A headless CMS becomes valuable when your business needs to manage content across multiple channels (web, mobile, in-app, etc.) while giving developers full flexibility over how content is presented.
You should consider using a headless CMS if:
-
You need to deliver content to multiple platforms (website, app, etc.)
-
Your marketing team wants to update content without relying on developers
-
You have complex content models (e.g., modular pages, dynamic blocks)
-
You’re running frequent A/B tests or campaign-driven content updates
-
You want to decouple the frontend from the backend for better performance and flexibility
Who Benefits Most from a Headless CMS?
-
Marketing-Led DTC Brands (Needing speed, agility, and omnichannel storytelling)
-
Enterprise Teams (Running multiple brands or locales with complex publishing needs)
-
Agencies & Developers (Building custom front ends with React, Next.js, etc.)
-
Tech-Forward Startups (Needing scalable content workflows without design limits)
Who May Not Need a Headless CMS (Yet)?
-
Your content needs are basic (static pages,)
-
You’re only focused on one platform (just a website, no app or third-party integration)
-
Your team doesn't have developers or prefers an all-in-one solution
-
You’re in the early MVP stage with limited content volume
For those just building a very simple ecommerce store from scratch, we don’t recommend starting with a headless CMS. If you're exploring how Medusa.js works, you can simply use its default storefront and manage content directly within Medusa itself.
But if you’re a growing or large brand, there’s no question — you need a headless CMS. Your marketing and content teams should be able to launch new pages, run A/B tests, and control each content block without developer bottlenecks.
In that case, the best headless CMS options include:
-
Directus CMS
-
Payload CMS
-
Strapi CMS
-
Sanity CMS
Why?

When and Who Should Use a PIM?
A Product Information Management (PIM) system becomes essential when your business deals with a large number of SKUs, multiple sales channels, or frequent product updates.
You should consider using a PIM if:
-
You sell across multiple platforms (e.g., website, marketplaces, B2B portals)
-
Your product data is spread across spreadsheets, tools, or teams
-
You manage different languages, regions, or catalogs
-
You need better control over product accuracy, enrichment, and workflow
-
Your marketing and product teams are constantly syncing over product content
Who Benefits Most from a PIM?
-
B2B Wholesalers & Distributors (Managing large catalogs, technical specs, custom pricing)
-
DTC & B2C Brands (Needing rich product storytelling and multichannel consistency)
-
Marketplaces or Retail Aggregators (Onboarding products from multiple vendors or sellers)
-
Manufacturers (Handling complex product structures and technical content)
Who May Not Need a PIM (Yet)?
If you're using Medusa.js and:
-
You have a small product catalog (under 100–200 SKUs)
-
You're selling on just one storefront (no marketplace or multichannel complexity)
-
Product data is simple and managed easily by developers or a small team
-
You're in the early MVP or pre-scale stage
Then you might not need a dedicated PIM yet. Medusa.js's built-in product module or a simple CMS like Directus or Strapi may be enough to manage your product content efficiently.
You can always integrate a PIM later as you scale.
ERP (Enterprise Resource Planning)
-
Open Source: Odoo
-
SaaS: NetSuite (Oracle)
When to choose: You manage inventory, procurement, finance, HR, and want full operational control. You need backend integration with your storefront and operations at scale.
When not to choose: You are an early-stage business with simple internal processes. Operations are handled manually or with lightweight tools.
OMS (Order Management System)
-
Open Source: Medusa.js
-
SaaS: Orderhive / Salesforce Order Management
When to choose: You handle high order volumes or fulfill across multiple channels and warehouses. You need advanced logic for shipping, returns, and split shipments.
When not to choose: You fulfill through a single warehouse or use dropshipping. Order volume is low and manageable via basic admin tools.
CRM (Customer Relationship Management)
When to choose: You track leads, sales pipelines, customer interactions, or B2B accounts. You plan to implement personalized marketing or customer lifecycle automation.
When not to choose: You only collect basic customer info through your store. You don’t have a sales or customer success process in place.
Inventory and Warehouse Management
When to choose: You track inventory across multiple locations or suppliers. You need restock automation, shipping rules, and warehouse coordination.
When not to choose: You only fulfill from a single partner. Inventory is minimal or manually managed.
Checkout and Payments
When to choose: You need global payment support or complex checkout customization. You want to support subscriptions, multiple currencies, or local payment methods.
When not to choose: You are using an all-in-one platform that already handles checkout. You want to avoid PCI and security compliance complexity.
Tracking and Analytics
When to choose: You need to track user behavior, product performance, and conversion funnels. You require marketing attribution and campaign performance data. You want custom dashboards and KPIs for team reporting.
When not to choose: You are pre-launch or just validating an MVP. Data insights are not driving current decisions yet.
User Behavior and Product Analytics
When to choose: You want heatmaps, session replays, or in-depth product analytics. You are optimizing UX or running CRO experiments.

-
Open Source: Metabase
-
SaaS: Looker Studio / Power BI / Tableau
When to choose: You want stakeholder-friendly dashboards. You need to connect multiple data sources for reporting or monitoring. You plan to scale performance tracking across departments.
When not to choose: You have a small team and don't need complex reports. You rely on built-in reports from your core tools.
A/B Testing and Personalization
-
SaaS: Optimizely / VWO / Google Optimize
When to choose: You run experiments across pages, content, or pricing. You need to improve conversion rate with evidence-based changes.
When not to choose: Your traffic is too low to reach statistical significance. You are pre-MVP and not investing in optimization yet.
Customer Support and Engagement
When to choose: You have an active customer base and need structured ticketing or live chat. You support multiple channels and teams.
When not to choose: You are early-stage with low support volume. You manage customer issues through direct email or WhatsApp.
Search and Discovery
-
Open Source: Typesense / Elasticsearch
-
SaaS: Algolia
When to choose: You offer a large catalog and need advanced search, filtering, and relevance. Search performance impacts conversion or discovery.
When not to choose: Catalog is small and browsable without search. Default product listing or basic filtering is enough.
CDN and Caching
-
SaaS: Cloudflare / AWS CloudFront / Akamai
When to choose: You want fast page loads, global delivery, and protection from traffic spikes. You serve a lot of media or dynamic content.
When not to choose: Your store is hosted on a managed platform with CDN built-in. You have low traffic and limited geographic reach.
Note: These are the common platforms we believe are perfect after years of working with Medusa.js. However, it depends on each client’s specific needs. The platforms you choose may vary based on customization and requirements. With a composable approach, you can always add or remove tools depending on your scale and needs.

ROI
Business Case Example: Welding Equipment Manufacturer Migrating from Salesforce to Medusa.js
Let’s consider a realistic example. Imagine you run a company that manufactures and sells industrial welding equipment. You currently operate your ecommerce store using Salesforce Commerce Cloud. While Salesforce is a well-established platform, you're now facing several major challenges:
-
High platform costs
-
Increasing operational expenses
-
Low online conversion rates
-
Limited flexibility and scalability
These issues are holding back your ability to grow and innovate. You're looking for a modern, more efficient solution — and Medusa.js Cloud offers exactly that.
Current Business Setup
-
Monthly revenue: $3,000,000 (3 million)
-
Net profit margin: 35%, giving you a monthly net profit of $1,050,000 (1.05 million)
-
Monthly site visitors: 100,000
-
Conversion rate: 1%
-
Average order value: $3,000
-
Monthly operational costs: $2,000,000 (2 million)
-
Salesforce platform cost: $1,500,000 (1.5 million) annually, or $125,000 per month
-
Total technology stack cost: $3,000,000 (3 million) annually
In this setup, you are spending heavily on tools and infrastructure but not seeing enough return due to poor conversion performance and lack of flexibility.
Post-Migration Expectations with Medusa.js
Once you migrate to Medusa.js Cloud, the following improvements are expected:
-
To this point: Increased Conversion Rate
Your ecommerce platform becomes faster and more optimized, increasing your conversion rate from 1% to 4%. This means monthly orders grow from 1,000 to 4,000.However, the increase in conversion rate and order volume can come from multiple factors. Using a headless CMS with medusa JS like Sanity or Directus allows you to ship new pages faster, run A/B tests, and optimize for conversion rate. Performance and site speed also improve significantly.
In the manufacturing sector, the cost per acquisition (CPA) tends to be lower because you do not need millions of buyers every day. Even with modest SEO improvements, headless commerce helps you get discovered by the right buyers. If a new distributor finds you, the long-term account (LTA) value can be anywhere from $100,000 to $200,000 or more per year.
So yes, while we’re still referring to conversion and order increases in general terms for this example, the real-world upside can be significantly higher depending on your business model.
-
Revenue Growth
With the same average order value of $3,000, your monthly revenue increases from $3,000,000 (3 million) to $12,000,000 (12 million) — an increase of $9,000,000 (9 million). -
Profit Increase
At a 35% profit margin, the additional revenue brings in an extra $3,150,000 (3.15 million) in profit per month. -
Operational Cost Savings
With better backend systems and automation, your operational costs decrease by 35%, saving you $700,000 (700 thousand) each month. -
Platform Cost Reduction
Medusa.js Cloud costs only $50,000 (50 thousand) annually, or about $4,200 per month, replacing Salesforce’s $125,000 per month, saving you $120,800 monthly. -
Tech Stack Cost Savings
Your annual technology stack cost drops from $3,000,000 (3 million) to $500,000 (500 thousand), saving about $208,000 per month.
Total Monthly Financial Impact
After the migration to Medusa.js, your monthly financial gains would include:
-
Additional profit from increased sales: $3,150,000 (3.15 million)
-
Operational cost savings: $700,000 (700 thousand)
-
Platform cost savings: $120,800 (120.8 thousand)
-
Technology cost savings: $208,000 (208 thousand)
Total monthly benefit: $4,178,800 (4.17 million)
Migration Cost and Payback Period
Assuming the total migration and implementation cost is $250,000 (250 thousand), this investment would be recovered in less than one month based on the gains outlined above.
Even if only 25% of the estimated improvements are achieved, you would still recover the investment in about one month.
Final Summary
Switching from Salesforce to Medusa.js Cloud for your ecommerce operations could unlock significant financial and operational benefits:
-
Increased net profit: $3,150,000 (3.15 million) per month
-
Operational savings: $700,000 (700 thousand) per month
-
Platform cost savings: $120,800 (120.8 thousand) per month
-
Technology cost savings: $208,000 (208 thousand) per month
-
Total monthly improvement: $4,178,800 (4.17 million)
-
Migration cost recovery: Less than 1 month
This transition not only reduces your costs but also helps you scale your business faster with a more flexible, developer-friendly, and high-performing commerce stack.
Note: The ROI mentioned is an estimate for medium-scale businesses. Actual results may vary based on your business size and strategy. However, with proper planning and execution, companies can see higher conversions, lower operational costs, faster team output, and reduced total cost of ownership (TCO).
How Much Does It Cost to Build an Ecommerce Site with Medusa.js?
There’s no straightforward answer to how much it costs to build a project—it entirely depends on the scope and requirements. For a basic eCommerce store with minimal complexity, our team can deliver a Medusa.js-based solution starting at $10,000.
However, for mid to large-scale brands building from scratch or migrating for a complete digital transformation, the cost can range significantly. When the scope includes storefront development, PIM integration, B2B eCommerce, CDP, and ERP systems, total costs can go from $50,000 up to $500,000 or even $1 million, depending on the scale and requirements.
In India, development costs are typically 40% lower than in regions like the UK or US. For instance, we’ve seen that a basic D2C setup with a custom Medusa.js storefront, headless CMS, and ERP may cost $50,000 to $100,000 abroad, while the same can be done for $20,000 to $30,000 in India.
A common misconception is that lower cost means lower quality. That’s not true. In India and other growing regions, the cost is lower mainly due to better access to talent and a high supply of skilled developers, not a compromise on quality.
In-house vs agency
So, should you build everything in-house or partner with an agency like ours?
Again, it depends entirely on your goals, timeline, and internal capabilities.
If your requirement is small, you might consider hiring freelancers or putting together an in-house team. But keep in mind that Medusa.js is not as straightforward or mature as platforms like WooCommerce or Shopify. There are not many ready-made templates or plug-and-play solutions available. It is still a relatively early-stage ecosystem, so you need strong backend developers who can work with a headless architecture and are comfortable digging into documentation or even modifying core logic.
In our experience, most companies that try to build with Medusa.js on their own face challenges in finding reliable developers who truly understand how it works. Larger, well-funded companies may be able to train their teams, but even then someone needs prior hands-on experience with Medusa.js to lead the effort.
A better approach, especially for scalable builds, is to bring on a trusted CTO who can lead and mentor the team, or to work with a specialized agency like ours. Many brands do not want the hassle of hiring, training, and learning through trial and error. That is where implementation partners like us become valuable.
We have refined our approach over time. We know how to find and train developers, and how to build systems that scale. If your project is large, you will need people who understand frontend frameworks, CMS integrations, Medusa backend, ERP connections, and data workflows. This means assembling a team with different skill sets, not relying on just one or two generalists.
When you work with us, you get an experienced, full-cycle team that is already aligned on the tools, processes, and best practices needed to deliver the right outcome with less risk and better efficiency.
Cost Breakdown: Hiring Teams vs Building In-House
Let’s assume you are a fashion brand looking to build an ecommerce platform with Medusa.js, Sanity as the headless CMS, and other related tools.
In the US, the average monthly salary for developers is roughly $10,000+. For experienced developers who understand both frontend and Sanity CMS, the cost can be around $20,000+ per month.
To build and manage your ecommerce project effectively, you would typically need:
-
At least one frontend developer
-
One backend developer
-
A project manager (PM)
-
A quality assurance (QA) specialist
This means a team of about 5 to 6 people. Over the course of the project, your total cost could reach between $600,000 and $800,000+.
Additionally, if you build in-house and your team lacks experience with Medusa.js and headless CMS, most of the time you will face trial and error, constantly debugging and rewriting boilerplate code. This can delay the launch to 6 to 8 months or more. The learning curve and repeated mistakes can significantly increase time and cost.
Using an Agency Like Us
For the same project, you can work with an experienced agency like ours that specializes in this tech stack.
Project development cost typically ranges from $100,000 to $150,000.
Support and maintenance is subjective and depends on your needs.
We offer 3 months of free support after project completion.
For smaller brands without an in-house team, ongoing support starts at $500 per month.
For larger businesses needing 300 to 400 hours per month including maintenance, new pages, and regular updates, costs typically range from $10,000 to $15,000+ or more per month.
Agencies focus exclusively on projects like these, so they have refined processes, reusable modules, and proven solutions that reduce development time and cost. Most of the work is repetitive and can be efficiently reused, allowing for faster launches and fewer errors.
Summary
Building in-house without experience often leads to delays, trial and error, and higher costs. Partnering with a specialized agency can save you time, reduce risk, and lower your overall investment while delivering quality results faster.
For large businesses undergoing digital transformation, the investment can be significant. We often hear clients hesitate during sales calls, wondering if they need to invest that much upfront or if they can start more gradually.
To address this, we have developed a solution called "LEAN" — a set of composable accelerators built to work seamlessly with Medusa.js. These accelerators help you launch faster and can reduce development costs by 35 to 40 percent since many core integrations—like two-way sync between Medusa.js and CMS, search functionality, ERP connections, and more—are already built and ready to use.
If you’re interested, please book a meeting with us. We can walk you through the accelerators and how they can benefit your project.

Businesses with an Existing Tech Stack but Wanting to Upgrade:
-
If you’re using older platforms (e.g., Shopify, WooCommerce, or Salesforce) and you’re looking for a more modular, cost-effective, and performant solution to scale your business, Medusa.js offers a great alternative.
Who Should Not Consider Medusa.js?
-
Small Businesses or MVPs:
-
If you’re just starting out or running an MVP with basic functionality (e.g., simple product pages, basic inventory management), Medusa.js may be overkill.
-
Simpler solutions like Shopify or WooCommerce can offer faster setup and easier management without the need for extensive technical expertise.
-
Businesses with Limited Developer Resources:
-
Medusa.js is a headless eCommerce solution, and building a custom storefront, managing integrations, and handling configurations require developer resources.

If you don’t have the technical expertise or development capacity, the learning curve and complexity could be a barrier.
-
Companies Seeking an All-in-One Solution:
-
If you prefer a fully managed, plug-and-play platform like Shopify or BigCommerce, which offers less technical management, then Medusa.js might not be the best choice.
-
For those who want minimal development work and easier maintenance, an all-in-one platform would be better suited.
-
Non-Technical Teams:
-
If your team doesn't have developers or you prefer to avoid working with backend systems or APIs, Medusa.js’s headless approach might not be the best fit.
-
A more traditional CMS with simpler workflows might be more appropriate.
-
Businesses Operating on a Single Platform:
-
If you only plan to sell on a single storefront (like a single website) with minimal third-party integrations, Medusa.js may not be necessary.
-
If your operations are basic, Medusa’s flexibility might not be fully utilized.
-
Companies Looking for a Ready-Made Solution:
-
If you’re looking for an out-of-the-box, simple setup that doesn’t require customization or deep technical expertise, Medusa.js might not be the right choice.
-
Platforms like Shopify, WooCommerce, or even Wix offer more straightforward solutions for quick deployment.
-
Budget-Conscious Startups with Tight Deadlines:
-
While Medusa.js offers great long-term benefits in terms of flexibility and cost reduction, the initial investment in development, including building out custom solutions, may not be suitable for businesses with small budgets or tight timelines.
In summary, Medusa.js is perfect for businesses looking for flexibility, scalability, and a developer-first approach, especially those that are willing to invest time and resources into building a custom, modular stack. However, if you're a small business, just starting out, or lack technical expertise, it may not be the best fit.
