Shopify Plus vs BigCommerce Enterprise: Which Fits Canadian Retailers in 2026?
Shopify Plus vs BigCommerce Enterprise. If you’ve spent any time researching the two, you’ve probably noticed something: almost every comparison claims one platform is the obvious winner.
But the problem is that there isn’t a winner.
6ixSenses builds on both Shopify Plus and BigCommerce Enterprise from Toronto, which puts us in an unusual position for a Canadian eCommerce agency: we have no reason to talk you into either one. The short answer is that Shopify Plus wins on ecosystem, checkout extensibility and speed to launch. And BigCommerce Enterprise wins on native B2B functionality, multi-storefront handling and, in some cases, lower total cost at scale.
We’ll cover where each is stronger, what the migration between them involves and the questions that settle the decision for most Canadian retailers.
The short answer
If you're primarily selling to consumers and want a huge ecosystem, fast development and a highly optimized checkout, Shopify Plus is hard to ignore.
If your business looks more like 500 wholesale customers, six pricing tiers, three storefronts and an ERP that absolutely cannot be upset, BigCommerce deserves a very serious look.
This is the quick version:

Both support multi-market commerce
But don’t forget that the platform itself is rarely the biggest problem.
Your business logic is.
If your pricing, fulfilment, inventory, ERP and customer-account rules are complicated, choosing the platform is only the beginning.
So, the real question is:
Which platform lets us run this business without building a small software company just to keep the store working?
That’s the question we'd start with.
And that is why the platform decision matters. But perhaps not for the reason you think. A platform with 500 features is not automatically better than one with 400.
What’s important is how many of those features solve problems your business actually has.
Pricing and total cost at enterprise scale
Because ‘How much does Shopify Plus cost?’ is usually one of the first questions we hear.
Shopify Plus currently starts at $3,650 CAD per month on a one-year term or $3,400 CAD per month on a three-year term for standard setups. Shopify says more complex, higher-volume businesses can move to variable platform pricing based on revenue and business model.
In the US, Shopify publishes Plus starting prices of US$2,500 per month on a one-year term or US$2,300 per month on a three-year term. For Canadian retailers, however, the Canadian pricing page is the more relevant reference point.
BigCommerce has also changed its pricing structure in 2026.
The old Enterprise terminology has effectively been replaced by Performance, its high-volume offering. Performance pricing is custom and currently starts at US$1,499 per month when billed annually.
So, at first glance, BigCommerce may look considerably cheaper. But don’t stop there.
The platform subscription is only one line on the spreadsheet.
Your real cost can include:
- platform fees
- payment processing
- third-party transaction fees
- apps
- ERP integrations
- middleware
- development
- agency support
- tax tools
- shipping software
- search and merchandising tools
- analytics
- ongoing maintenance
And then things get interesting.
Shopify Plus transaction fees
If Shopify Payments is your primary payment gateway, Shopify says third-party transaction fees are waived.
If you use a third-party processor as your primary gateway, Shopify Plus currently charges 0.20% per transaction on top of your processor’s fees.
For a smaller enterprise store, that might not be a major concern.
For a retailer processing tens of millions of dollars a year? Now we’re talking about real money.
BigCommerce payment fees
This is one area where older Shopify vs BigCommerce comparisons can get you into trouble.
You’ll still see articles claiming that BigCommerce has no transaction fees.
In 2026, that’s too broad.
BigCommerce’s new pricing structure, introduced on June 1, 2026, applies an Open Payment Provider Fee to eligible orders on its self-service plans when merchants use providers outside its embedded payment provider network. The current published rates are 2.0% for Core, 1.0% for Growth and 0.6% for Scale. Performance has a 0% Open Payment Provider Fee under contracted terms.
So if yo’re comparing enterprise platforms, don’t use the old BigCommerce has zero transaction fees. Use the more useful question: What will our actual payment architecture cost at our expected volume?
Then there’s the app bill
This is where another cost can quietly grow teeth.
Shopify’s enormous app ecosystem is one of its biggest strengths. Need reviews? There’s an app. Loyalty? Plenty. Advanced search? Yes. Something incredibly niche that only a few thousand retailers need? There’s probably an app for that too.
That’s fantastic. Until you realize you’ve subscribed to 14 of them.
BigCommerce also has a large ecosystem of third-party applications. Although its native functionality can reduce the need for external tools in areas such as B2B pricing and customer segmentation. Its Performance plan, for example, includes native Price Lists, and lower plans do not.
Our advice: don’t compare the monthly platform price.
Build a five-year total cost of ownership model. That’s where you'll find the real answer.
B2B and wholesale: where BigCommerce gets interesting
This is probably the clearest differentiator in the Shopify Plus vs BigCommerce Enterprise comparison.
BigCommerce has long leaned heavily into B2B commerce. Its platform supports customer groups and Price Lists, allowing different versions of catalogue pricing to be assigned to different customer groups, sales channels and currencies.
And that matters.
Imagine you’re a Canadian manufacturer selling commercial equipment.
You have:
- regular retail customers
- approved wholesale accounts
- national distributors
- contractors
- large enterprise buyers
Your national distributor gets one price.
Your smaller wholesale customer gets another.
Your biggest account has negotiated pricing.
Some products aren't available to everyone.
Certain buyers need purchase orders.
Some orders require a quote before anyone can click Place Order.
Suddenly, ‘Does the platform support B2B?’ is not a very useful question. You need to know whether it supports your version of B2B.
BigCommerce has a strong starting point here, particularly where customer-specific pricing is central to the business. Its Price Lists can override variant-level catalogue prices and be assigned to customer groups or channels.
But don’t write Shopify off for B2B
This is where older Shopify comparisons are starting to age badly. The idea that Shopify is only for B2C is simply no longer true.
Shopify Plus includes native B2B capabilities for wholesale businesses. And Shopify has continued expanding B2B functionality throughout 2026. In April 2026, Shopify extended foundational B2B features to Basic, Grow and Advanced plans. This includes company profiles, custom catalogues, volume pricing and payment terms. More advanced capabilities such as unlimited catalogues and direct catalogue assignment to companies and locations remain Plus-only.
So if you’re a DTC brand that has recently started selling wholesale, Shopify Plus can be more than capable.
The question becomes whether your B2B requirements are simple enough to fit the native tools.
If they are, great.
If you need a labyrinth of customer-specific pricing, approval workflows, quotes, unusual purchasing rules and ERP-driven business logic, BigCommerce can still have an advantage.
Our take
Start with BigCommerce on the shortlist for Complex B2B.
Shopify Plus deserves serious consideration for DTC-first with growing wholesale.
That is probably the clearest dividing line in this entire comparison.
Checkout, customization and control
Another simple question: Can we customize the checkout?
Yes. But what you mean by customize matters.
Shopify Plus provides Checkout UI Extensions for defined areas of the checkout. It includes the information, shipping and payment steps. Shopify's current developer tools let merchants add custom UI and logic while working within Shopify's checkout architecture.
Shopify Functions can also be used to customize certain commerce logic. And that’s a big deal.
You can build experiences around your business requirements without taking complete ownership of the checkout infrastructure.
For example, you might need:
- custom checkout messaging
- specialized payment logic
- shipping rules
- custom discounts
- validation
- B2B-specific behaviour
- custom post-purchase experiences
Shopify’s approach is increasingly about extending checkout rather than hacking checkout.
That's really a benefit for many enterprise businesses.
You get flexibility without creating a checkout that becomes a maintenance project every time the platform releases an update.
BigCommerce takes the open route
BigCommerce's broader proposition is more open and API-driven.
That can be attractive if you have an experienced internal technology team, a headless architecture, unusual frontend requirements or a business that wants significant control over the commerce stack.
And the trade-off is that freedom comes with responsibility.
If you have complete control over everything, someone has to own everything.
That means development hours, testing, maintenance and upgrades.
The real cost of custom checkout
This is where we tell clients to slow down.
A request for a custom checkout might actually mean:
‘Our ERP needs to approve an order before payment.’
Or:
‘Different customer types need different shipping options.’
Or:
‘Our sales team needs to override pricing.’
Or:
‘We have a complicated tax setup.’
Those aren’t tiny checkout tweaks. They’re business processes. So, before choosing a platform for its custom checkout, write down exactly what you want the checkout to do.
Then price the implementation and ongoing maintenance.
Integration with ERP, POS and fulfilment
Your customer sees the storefront. Your operations team sees everything else.
ERP.
Inventory.
Warehouse management.
POS.
Shipping.
Returns.
CRM.
3PL.
And probably a few spreadsheets nobody is brave enough to delete.
This is why an enterprise platform comparison shouldn’t stop at the storefront.
Both Shopify and BigCommerce have broad integration ecosystems. For Canadian retailers, the more important question isn't whether an ERP connector exists. It’s whether it can support your actual data flows, business rules and operational volume.
Think about systems such as:
- NetSuite
- Odoo
- SAP Business One
- Microsoft Dynamics
- POS platforms
- warehouse management systems
- 3PL platforms
- CRM systems
- payment gateways
A connector that technically works isn't necessarily a good enterprise integration.
Here’s the important bit
You shouldn’t be asking:
‘Does Shopify integrate with our ERP?’
or:
‘Does BigCommerce integrate with our ERP?’
Ask:
‘How exactly will our data move between these systems?’
That's a much better question.
For example:
Shopify → middleware → ERP → warehouse → 3PL
might be a better architecture than:
Shopify → 14 individual integrations → chaos.
The same applies to BigCommerce.
When middleware becomes necessary
Middleware is useful when multiple systems need to exchange data while following different rules.
You might need:
- order data from ecommerce to ERP
- inventory from ERP to ecommerce
- fulfilment status from the warehouse to ecommerce
- customer data from ecommerce to CRM
- tracking information from the 3PL back to the storefront
- pricing from ERP to B2B accounts
Instead of creating a web of fragile point-to-point integrations, middleware can act as the traffic controller. This is not necessarily a weakness of Shopify or BigCommerce.
It’s simply what happens when a business grows complicated enough to need an integration layer.
API limits matter at scale
At enterprise volume, APIs aren’t an exciting technical detail. They’re infrastructure.
Shopify uses calculated GraphQL query costs and rate limits to manage API usage, with higher limits available to Plus merchants. That means integrations need to be designed around efficient queries, batching, caching, queues, retries and sensible synchronization rather than repeatedly polling the platform.
And the bigger lesson is:
A platform can have a great API and still have a terrible integration if the architecture is poorly designed.
Don't choose based on the word API. You need to choose based on what you need the API to do.
Canadian and cross-border specifics
Now we get to the part that makes Canadian ecommerce especially interesting.
Canada has provinces. Provinces have taxes. And, naturally, they don't all make things equally simple. Then you decide to sell into the US. Now you've added another layer. Then you add USD pricing. Then a US warehouse. Then cross-border fulfilment. Then someone asks why the refund amount doesn't match the original order in the accounting system.
Welcome to enterprise ecommerce.
CAD and USD selling
To Canadian retailers, multi-currency is not simply about displaying a US dollar symbol.
You also need to think about:
- payment processing
- settlement currency
- exchange rates
- refunds
- ERP records
- accounting
- inventory valuation
- pricing rules
- rounding
Shopify Plus supports multi-market commerce and Canadian merchants can configure CAD and USD payout arrangements where eligible. Shopify also positions Plus around online, retail and B2B selling from one platform.
BigCommerce supports multi-currency pricing. And Price Lists can contain price records in multiple currencies. This gives businesses more control over customer- or channel-specific pricing.
But you can’t stop at "Can the platform show USD?"
Ask:
- Where is the exchange rate determined?
- Where are refunds converted?
- Which currency does the ERP record?
- What currency does the payment gateway settle?
- How are CAD and USD prices maintained?
Those questions are considerably less glamorous than picking a homepage design.
They're also the ones that can save you headaches six months after launch.
Canadian tax configuration
Canada’s tax environment adds another layer of complexity.
Depending on where you're registered and where you sell, your setup may involve GST, HST, PST, RST and QST.
Both platforms can support sophisticated tax configurations. But your implementation still needs to reflect your actual registration and compliance requirements.
And there is an important distinction:
Your ecommerce platform can calculate tax. It doesn't decide your legal tax obligations.
Work with your tax adviser to determine where and how your business should register. Then make sure your ecommerce and ERP systems reflect those requirements correctly.
Shipping and 3PL
Canadian retailers can also have a surprisingly complicated shipping stack.
Canada Post. Purolator. UPS. FedEx. Regional carriers. Local delivery. Warehouse pickup. 3PLs. And then the US.
Both Shopify and BigCommerce have broad shipping and fulfilment ecosystems. The real question is whether your chosen integration can handle your workflow.
Can it manage multiple warehouses?
Can it split orders?
Can it sync tracking?
Can it handle backorders?
Can it pass the right shipping data to your ERP?
Can it manage returns?
That is the level at which enterprise platform decisions should be made.
What about multiple brands and storefronts?
Now imagine your company owns three brands. Or perhaps you sell in Canada and the US but need different catalogues, pricing and content. Or you operate separate B2B and DTC storefronts.
This is where BigCommerce’s multi-storefront approach becomes particularly interesting.
BigCommerce allows businesses to manage multiple storefronts from a central platform. This makes the model attractive for brands operating across different markets, brands or customer segments.
Shopify Plus can also support multiple stores. But the commercial structure is important. Shopify’s current Plus pricing includes a main store and expansion stores. The additional stores and separate brands can affect the overall commercial arrangement.
So, don't just compare storefront templates for a multi-brand organization.
Compare the commercial model behind those storefronts.
It could make a significant difference.

FAQs
Is Shopify Plus or BigCommerce Enterprise better for Canadian B2B businesses?
For many Canadian B2B sellers, BigCommerce requires less custom development when complex pricing and customer-specific catalogues are central to the business. Its Price Lists can be assigned to customer groups and channels. This is quite useful for wholesale models with different pricing structures.
Shopify Plus has significantly narrowed the gap with native B2B functionality, including company profiles, catalogues, payment terms and other wholesale tools. Shopify also expanded foundational B2B features to non-Plus plans in 2026. It also keeps more advanced capabilities exclusive to Plus.
We’d put BigCommerce higher on the shortlist if your pricing logic is genuinely complex. If you’re primarily DTC with a growing wholesale operation, Shopify Plus might be the better overall fit.
How much does Shopify Plus cost in Canada?
Shopify Plus currently starts at $3,650 CAD per month on a one-year term or $3,400 CAD per month on a three-year term for standard setups. More complex, higher-volume businesses may move to variable platform pricing.
If Shopify Payments is your primary gateway, Shopify says third-party transaction fees are waived. If you use a third-party processor as your primary gateway, Plus charges 0.20% per transaction in addition to processor fees.
You need to remember to budget separately for apps, payment processing, integrations, development and ongoing support.
Can you migrate from BigCommerce to Shopify Plus?
Yes. Migration is possible in both directions.
Products, customers and order history can generally be transferred. But the difficult part is rebuilding the ecosystem around that data.
A serious enterprise migration may involve:
- product and variant mapping
- customer data
- order history
- theme redevelopment
- B2B pricing
- applications
- checkout logic
- ERP integrations
- payment gateways
- fulfilment
- SEO metadata
- URL redirects
8 to 16 weeks can be a reasonable starting point for a relatively controlled enterprise migration. But complex ERP, B2B, multi-brand or international projects can take considerably longer.
And please don’t leave SEO until launch week. Your redirect map should be planned alongside the migration from day one.
Is BigCommerce cheaper than Shopify Plus?
It can be. But not automatically. BigCommerce Performance currently starts at US$1,499 per month billed annually. But the total cost depends on payment providers, integrations, apps, development and your contracted terms.
Shopify Plus starts at $3,400 CAD per month on a three-year term. But its ecosystem and native capabilities can reduce development or operational costs in some businesses.
You need to compare total cost of ownership, not the monthly subscription.
Which is better for high-volume Canadian retailers?
Both can support high-volume commerce. Shopify Plus is particularly compelling for DTC-led businesses focused on conversion, marketing, international selling, retail and a broad technology ecosystem. BigCommerce can be particularly compelling when high volume comes with complex B2B, multi-storefront or integration requirements.
The question isn't simply how many orders you process. It’s how complicated each order is.
Which platform is better for multiple brands?
BigCommerce has a strong multi-storefront proposition. It allows businesses to manage multiple storefront experiences from a central platform.
Shopify Plus can also support multiple stores, but businesses with several distinct brands should look closely at the commercial structure, expansion-store requirements and whether separate Plus arrangements make more sense.
For a multi-brand organization, this deserves a detailed commercial and technical comparison before you choose.
