Shopify and Square Online are both solid e-commerce platforms. The problem is most St. Louis business owners pick one based on name recognition or what a friend recommended, not based on how they actually sell.
That leads to a pretty common situation. A retail shop ends up on Shopify when their in-person Square POS setup would have connected everything automatically on Square Online. Or a product-heavy brand picks Square Online and hits a ceiling six months later when they need features the platform wasn’t built for.
The right answer depends on your business, not on which platform has better marketing.
We work with both as a Shopify Partner and Square Online Certified Partner in St. Louis, so this comparison isn’t a pitch for either one. It’s a breakdown of what each platform actually does well, where each falls short, and which type of St. Louis business is the right fit for each.
What is Shopify?
Shopify is a dedicated e-commerce platform built from the ground up for selling online. It launched in 2006 and has grown into one of the most widely used e-commerce platforms in the world, powering everything from small independent retailers to large consumer brands.
The core strength of Shopify is its depth. It handles complex product catalogs with hundreds of variants, supports advanced marketing tools, and has an app ecosystem with thousands of integrations covering everything from email marketing to inventory management to wholesale ordering. If you can think of a feature an online store might need, there’s likely a Shopify app for it.
Shopify also has strong theme options, giving St. Louis businesses more control over how their online store looks and feels compared to most competing platforms.
It does have a physical POS option through Shopify POS, but the platform was built for online selling first. Businesses that run primarily in-person with online as a secondary channel sometimes find the POS side less intuitive than dedicated point of sale systems.
For St. Louis businesses that sell primarily online, have a large product catalog, or are planning to scale, Shopify is worth a serious look. As a Shopify Partner in St. Louis, we set these stores up regularly and know where the platform delivers and where it has limits.
What is Square Online?
Square Online is the e-commerce arm of the Square ecosystem. Where Shopify was built for online selling first, Square Online was built to extend what Square POS already does into an online storefront.
That distinction matters more than most people realize. If your St. Louis business already runs on Square POS, Square Online pulls your existing product catalog, inventory, and sales data into an online store automatically. There’s no manual syncing, no duplicate data entry, and no separate platform to manage. What sells in-store updates online and vice versa in real time.
Square Online is also simpler to set up than Shopify. The tradeoff is customization. You get clean, functional store templates but fewer design options than Shopify offers. For most local St. Louis retail shops, restaurants, and service businesses, that’s a reasonable tradeoff. The store looks professional, works well on mobile, and connects directly to how you already take payments.
Where Square Online starts to show limits is with larger product catalogs, advanced marketing needs, and businesses that sell primarily online without a physical location. For those situations, Shopify is usually the stronger fit.
As a Square Online Certified Partner in St. Louis, we build and configure these stores regularly across retail, food and beverage, and service businesses.
Side by Side Comparison
Here’s how Shopify and Square Online stack up across the six factors that matter most for a St. Louis business making this decision.
1. Ease of Setup
Square Online is faster to get running, especially if you’re already on Square POS. Your catalog imports automatically, your payment processing is already connected, and you can have a functional online store live in a day. Shopify requires more initial configuration but has a more guided onboarding process than it used to. For a brand new business with no existing POS system, both are manageable. For a business already using Square, Square Online wins this one clearly.
2. Pricing and Transaction Fees
Both platforms have a free entry tier. Square Online’s free plan lets you sell online immediately, though it includes Square branding and limited customization. Shopify’s free tier is a trial only. Paid plans start at $49/month for Square Online (Square Plus) and $29/month for Shopify Basic, though Shopify charges an additional transaction fee on top of payment processing if you’re not using Shopify Payments. For St. Louis businesses processing moderate volume, the real monthly cost difference between the two platforms is smaller than it looks on paper once you factor in all fees.
3. Design and Customization
Shopify wins here. The theme library is larger, the customization options go deeper, and the overall design ceiling is higher. St. Louis businesses that care about a distinctive brand experience online will find more flexibility in Shopify. Square Online templates are clean and professional but limited in how far you can take them without custom code. If your priority is getting a good-looking store live quickly rather than building something highly customized, Square Online is sufficient.
4. Inventory and POS Integration
Square Online wins this one and it’s not close. If you have a physical location using Square POS, Square Online keeps your in-store and online inventory in perfect sync without any additional setup or third-party tools. Shopify has its own POS system, Shopify POS, but it’s a separate product and switching from Square to Shopify POS is a bigger lift than most St. Louis business owners want to take on. If your in-person and online inventory need to stay connected, Square Online is the cleaner solution.

5. App Integrations and Scalability
Shopify has one of the largest app ecosystems in e-commerce, with thousands of integrations covering marketing, logistics, wholesale, subscriptions, and more. For St. Louis businesses planning to grow significantly, add sales channels, or build out complex marketing automation, Shopify scales further. Square Online integrates well within the Square ecosystem but has fewer third-party options. It works well for businesses that need a solid, connected store without heavy customization or complex integrations.
6. Support and Onboarding
Both platforms offer support, but neither is known for fast, detailed responses on complex setup issues. This is one of the practical reasons St. Louis businesses work with a certified partner rather than going direct. A Shopify Partner or Square Online Certified Partner handles the setup, troubleshooting, and configuration so you’re not working through support tickets when something isn’t right. The platform support is a backstop, not a setup service.
Neither platform is universally better. Square Online wins on POS integration and simplicity. Shopify wins on design flexibility and scalability. The right choice for your St. Louis business comes down to how you sell today and where you’re headed in the next two to three years.
Who Should Choose Shopify?
Shopify is the stronger fit for certain types of St. Louis businesses, and being clear about that upfront saves a lot of time and money down the road.
You sell primarily online
If your main revenue channel is your online store and your physical presence is secondary or nonexistent, Shopify was built for you. The platform’s depth in product management, checkout optimization, and marketing tools reflects years of development focused on online-first selling.
You have a large or complex product catalog
Businesses with hundreds of products, multiple variants, and complex inventory needs will find Shopify handles that scale more comfortably than Square Online. The filtering, organization, and bulk editing tools are more robust at higher catalog sizes.
You’re building a brand, not just a store
St. Louis businesses that want a distinctive online presence with custom design, unique customer experience, and strong brand identity have more to work with on Shopify. The theme ecosystem and customization depth give you room to build something that doesn’t look like every other small business store.
You’re planning to grow
If your two year plan involves adding sales channels, building out email marketing automation, launching a wholesale side, or scaling to a larger operation, Shopify’s app ecosystem supports that growth without needing to migrate platforms later.
You need advanced marketing tools
Shopify integrates cleanly with Google, Meta, TikTok, and most major marketing platforms. For St. Louis businesses running paid advertising or building out organic content strategies alongside their store, those integrations matter.
The investment is real. A properly built Shopify store costs more upfront than a Square Online setup, and the monthly platform costs are higher at the comparable feature tier. As a Shopify Partner in St. Louis, we scope Shopify projects based on what your business actually needs, not the most expensive option available.
Who Should Choose Square Online?
Square Online is the right call for a specific type of St. Louis business, and when it fits, it fits well.
You already use Square POS
This is the clearest case. If your St. Louis business already runs on Square POS, adding Square Online is the most logical path to selling online. Your catalog is already there, your payment processing is already set up, and your inventory stays in sync across both channels without any additional tools or manual work.
You run a food and beverage business
Square Online has strong built-in support for restaurants, coffee shops, bars, and food trucks. Online ordering, pickup scheduling, delivery options, and menu management are all native to the platform. For St. Louis food and beverage businesses that want to add online ordering without a third-party service eating into margins, Square Online handles it cleanly.
You’re a local retail shop or service business
If most of your revenue comes from in-person sales and you want an online store that reflects your current inventory without a lot of maintenance, Square Online delivers that with minimal overhead. It’s not trying to be the most customizable platform. It’s trying to be the most connected one for businesses that sell in person first.
You want a simpler setup and lower starting cost
Square Online’s free plan lets you sell online immediately. For St. Louis business owners who want to test online selling before committing to a higher monthly platform cost, that’s a low-risk way to start.
You don’t need heavy customization
If a clean, professional store that works well on mobile and connects to your existing Square setup is enough, Square Online covers it without overcomplicating things.
As a Square Online Certified Partner in St. Louis, we configure these stores for retail shops, restaurants, and service businesses across the metro area and beyond.
What If You’re Still Not Sure?
Shopify and Square Online have enough overlap that the decision isn’t always obvious, especially if you’re starting fresh without an existing POS system or strong preference either way.
A few questions worth sitting with before deciding. Do you have a physical location already running on Square? That tips toward Square Online. Are you building a brand that lives primarily online with a large product catalog? That tips toward Shopify. Are you expecting significant growth in the next two years that will require advanced marketing tools and integrations? Shopify scales further.

FAQ: Shopify vs Square Online for St. Louis Businesses
Is Shopify or Square Online cheaper for a St. Louis small business?
It depends on your starting point. Square Online has a free plan that lets you sell online immediately. Shopify’s paid plans start at $29/month but include more e-commerce features at that tier. Once you factor in transaction fees, app costs, and setup investment, the real cost difference narrows. For businesses already on Square POS, Square Online is almost always the lower cost path. For online-first businesses, Shopify’s pricing reflects the depth of what you’re getting.
Can I use Square POS with Shopify?
Not natively. Shopify has its own POS system called Shopify POS, and Square has Square Online. The two ecosystems don’t connect directly. If you’re running Square POS in-person and want to add online selling, Square Online is the cleaner solution. If you want to use Shopify for everything including in-person sales, you’d need to migrate your POS to Shopify POS as well.
Which platform is easier to set up for a St. Louis business?
Square Online is generally faster to get live, especially if you’re already using Square POS. Shopify has improved its onboarding significantly but requires more initial configuration for a fully functional store. For both platforms, working with a certified partner in St. Louis gets you live faster and avoids the common setup mistakes that slow most business owners down.
Does Square Online work for product-heavy stores?
It works up to a point. Square Online handles moderate catalog sizes well, but businesses with hundreds of products, complex variants, and heavy inventory management needs will find Shopify more capable at that scale. If your catalog is growing fast, Shopify is worth the extra investment.
Can a St. Louis business use both Shopify and Square Online at the same time?
Technically yes, but it’s not recommended. Managing two separate e-commerce platforms means duplicate inventory management, separate reporting, and higher monthly costs. Most St. Louis businesses are better served by picking the platform that fits their primary selling channel and building from there. If you’re unsure which one that is, a free consultation with a Shopify Partner and Square Online Certified Partner will give you a clear answer faster than trying to run both.
