Choosing the right platform is the key to thriving beyond borders
Singapore is the best place in Southeast Asia for cross-border trade. 86% of all online purchases and sales involve buyers or sellers from other countries. For B2B platforms that work in this space, picking the right ecommerce infrastructure isn’t just a technical choice; it also affects ROI, operational efficiency, and competitive positioning.
The debate over platforms is increasingly focused on two strong but very different options: Medusa.js, an open-source headless commerce engine that is becoming more popular with developers, and Shopify Plus, an enterprise SaaS platform that global brands trust. Both can run complex B2B operations, but they do so in different ways when it comes to customization, cost structure, and control.
This in-depth comparison looks at Medusa.js Singapore deployments and Shopify Plus alternatives that Singapore businesses are considering, with a focus on cross-border B2B needs. We’ll look at the features of each platform, the total cost of ownership over 36 months, performance benchmarks from real implementations in Singapore, and give you a way to decide which platform gives your business model the best return on investment.
Platform Insights: Philosophy and Design
The first step in making smart choices is to know what makes these B2B ecommerce platform Singapore options different from each other.
Medusa.js: An Open-Source Engine for Business
Medusa.js is an open-source headless commerce platform built on Node.js that lets developers fully control the commerce backend. Medusa is built using modern tools like TypeScript and PostgreSQL. It has an API-first architecture that lets the commerce engine work separately from the frontend presentation layer.
Some of the most important features are that you can access the full source code, you don’t have to stick with one vendor, you can add extensions through a modular plugin system, and you can host it yourself or in the cloud. Medusa is great for businesses that need a lot of customization, complicated pricing rules, or the ability to work with older business systems. Because the platform is open-source, there are no licensing fees, but you need to know how to use and maintain it.
Shopify Plus is a SaaS platform for businesses
Shopify Plus is the opposite: it’s a fully managed, hosted SaaS solution that takes care of security, infrastructure, updates, and compliance on its own. Plus is built on Shopify’s proven commerce platform and adds features for businesses, such as custom checkout flows, advanced automation through Shopify Flow, and dedicated account management.
The platform’s strength comes from the fact that it is ready to use right away. Businesses can quickly set up their stores using a large library of themes, add functionality with thousands of apps, and take advantage of Shopify’s huge payment processing network. However, customization is limited by the platform, and transaction fees and subscription costs are ongoing costs that grow with revenue.
Basic Trade-offs
The choice is basically between control and long-term cost efficiency (Medusa.js) and speed to market and managed operations (Shopify Plus). You have to build more features from scratch with Medusa.js, but it gives you unlimited flexibility. Shopify Plus comes with a lot of built-in features, but you can’t customize them outside of the platform. There is no one best way to do things; the best choice depends on the needs of the business, its technical capabilities, and its strategic goals.
What Cross‑Border B2B Opportunities Exist in Singapore?
Singapore is a regional trade hub, so it has specific platform needs that most ecommerce solutions can’t meet.
The challenge of utilizing various currencies
Cross-border B2B platforms must be able to accept Singapore Dollars (SGD), US Dollars (USD), Malaysian Ringgit (MYR), Indonesian Rupiah (IDR), and other currencies from the area without any problems. This needs more than just simple conversion; it also needs real-time updates of exchange rates, currency preferences for each customer, and accurate financial reporting in more than one currency.
You can set different prices for different areas with Medusa.js, which comes with built-in support for multiple currencies. Shopify Payments makes it easy to accept payments in different currencies on Shopify Plus. However, it doesn’t work in all Southeast Asian markets yet, so you might need to use a third-party payment processor.
Items that are cheap and follow GST rules
Because of Singapore’s Goods and Services Tax (GST) rules, like the recent removal of low-value goods relief, you have to do complicated tax calculations at the register. Platforms need to figure out the right GST application based on the type of customer (B2B vs. B2C), the value of the transaction, and the types of products, and then make tax invoices that follow the rules.
Both platforms let you automate taxes, but Medusa.js lets you change tax rules in more detail for tricky B2B situations like reverse-charge mechanisms. Most of the time, Shopify Plus has built-in tools that help you follow the rules for taxes. But if you have more complicated B2B needs, you might need to use apps.
Bringing together regional logistics
To make cross-border fulfillment work well, you need to work with regional carriers like SingPost, DHL eCommerce, FedEx, and local last-mile providers in Southeast Asia. You can’t change the fact that you need shipping quotes in real time, automatic label generation, and tracking that works together.
You can connect to any logistics provider you want with Medusa.js’s plugin architecture, but you have to build each connection yourself. Shopify Plus has a lot of carrier integrations already built into its app ecosystem, which makes it easier to set up logistics with these connectors.
Data Residency and Following the PDPA
In Singapore, the Personal Data Protection Act (PDPA) and the data residency requirements for business customers mean that customer data often has to stay in Singapore or other approved areas. This has an impact on where to host and what third-party services to use.
You have complete control over where your data is stored with Medusa.js’s self-hosted model. You can put it on AWS Singapore, DigitalOcean Singapore, or your own data centers when you need to. Shopify Plus runs on Shopify’s global infrastructure, which means that data may not stay in Singapore unless

Hybrid Approaches Worth Considering
Some businesses in Singapore use hybrid strategies that combine the best features of different platforms.
- Headless Shopify: Shopify Plus can help you run your business, and Next.js or React can help you build your own front end. This will make the front end better and let you use Shopify’s managed infrastructure.
- Medusa Frontend + Shopify Backend: Use Shopify’s tools to make shopping more fun for your customers
- Parallel Operations: While you make modifications, use both platforms for distinct groups of clients or marketplaces.
These solutions make the design more complex, yet they may be the best option in some cases.
Conclusion: ROI Depends on Strategic Alignment
Medusa.js and Shopify Plus don’t always deliver Singapore B2B ecommerce the best return on investment (ROI). The best option is the one that fits the platform’s needs, technology, and growth route.
Shopify Plus is a terrific option for businesses who want to get started quickly, have someone else handle their business, and have everything operate right away. When sales are low, the platform’s managed infrastructure and ecosystem make it easy and cheap to enter into the market. Shopify Plus is usually the best choice if your business doesn’t need a lot of bespoke work and produces less than $5 million a year.
Medusa.js can help businesses with technical skills and complicated needs save money over time and give them a lot of freedom. When GMV is over $10 million, the savings on transaction costs and the opportunity to make changes usually make the higher initial cost worth it. Costs will be low as businesses expand and develop because the platform is open source.
If you want to do business in Singapore across borders, you need to think about where to keep data, how to connect numerous sites, and how to make things function better. You can do these things using Medusa.js, but you need to know a lot about technology to get the most out of it.
For Singapore’s cross-border B2B market specifically, consider data residency requirements, regional integration needs, and performance optimization priorities. Medusa.js offers advantages in these areas but requires technical expertise to realize fully.
