BigCommerce vs Shopify: How transaction fees impact your eCommerce profitability

Pricing assumptions drive platform decisions more often than most teams realise. Many brands choose between BigCommerce vs Shopify based on a simple belief: one charges transaction fees, the other does not. That assumption has shaped countless platform migrations, cost projections, and margin expectations over the years.

That logic no longer holds.

With BigCommerce introducing a new fee structure for third-party payment providers, the comparison between BigCommerce vs Shopify shifts from a surface-level pricing discussion to something more fundamental. It becomes a question of how each platform structures cost, how predictable those costs are, and how they scale alongside your revenue.

For eCommerce teams operating on tight margins, this is not a minor update. Transaction fees directly influence contribution margin, especially as order volume increases. A difference of one percent may look small on paper, but at scale, it compounds quickly and affects profitability in ways that are often underestimated during platform selection.

This is where most comparisons fall short. They isolate subscription fees or highlight headline percentages, but rarely connect those numbers to operational reality. Payment methods, regional preferences, app dependencies, and growth trajectories all play a role in how much a platform actually costs over time.

This article explains:

• How transaction fees work in BigCommerce vs Shopify
• What changed in BigCommerce’s pricing model
• How fees influence real eCommerce profitability at scale
• Which platform aligns better with different growth strategies

To make a grounded comparison, we need to start with how transaction fees actually work in BigCommerce vs Shopify today.

BigCommerce vs Shopify: understanding transaction fees in 2026

At a glance, transaction fees look straightforward. A percentage per order, applied at checkout. In reality, the structure behind those fees differs significantly between the two platforms, and that difference shapes how costs behave as your business grows.

BigCommerce’s original pricing advantage

For years, BigCommerce positioned itself around a clear promise: no platform transaction fees. This gave merchants a level of flexibility that was hard to ignore:

• Choose any payment provider without additional platform penalties
• Optimise for lower processing rates depending on region or volume
• Avoid being tied into a single payment ecosystem

Especially for brands operating across multiple markets or relying on local payment methods, the ability to avoid platform-level fees translated into meaningful savings. BigCommerce became known as the cost-efficient alternative, particularly for teams that prioritised control over their payment stack.

What changed with the new fee structure

That positioning is now shifting.

Starting June 1, 2026, BigCommerce introduced an Open Payment Provider Fee on all self-service plans. As detailed in the official BigCommerce pricing update, any gateway not on BigCommerce’s approved Embedded Provider list is now subject to an additional platform fee per order.

The Embedded Provider list includes Stripe, PayPal/Braintree, Adyen, Checkout.com, Klarna, and Afterpay, among others. Everything outside that list triggers the fee, assessed at order level based on which provider actually processed the transaction.

This has two immediate implications. First, the flexibility that once defined BigCommerce now comes with a trade-off. Merchants can still choose their preferred provider, but that choice may introduce an extra cost layer. Second, the pricing model becomes less distinguishable from competitors. The absence of transaction fees was not just a feature. It was a core differentiator. Removing it changes how the platform needs to be assessed.

Shopify’s transaction fee model

Shopify takes a different approach. Instead of removing transaction fees entirely, it operates a conditional model tied to payment provider choice.

Shopify Payments is available across the US, UK, Australia, Canada, Ireland, and most of Europe. For merchants in those markets, the platform transaction fee is zero. Standard payment processing fees from Shopify Payments still apply. On the Grow plan, the base rate starts at 2.7% + $0.30 per online transaction, though rates may vary depending on card type and the buyer’s country. Check the Shopify pricing page for the exact rate in your market. The fee applies when merchants use third-party gateways, whether for regional preferences or negotiated rates. That flexibility comes at a cost that needs to be factored into profitability calculations.

Shopify effectively aligns incentives. By encouraging merchants toward its native payment solution, it simplifies the cost structure into a single transparent layer. There is also an operational upside: fewer integrations to manage, consolidated reporting within one system, and reduced dependency on external providers.

Key difference: flexibility vs predictability

When comparing BigCommerce vs Shopify, the real difference is no longer just about whether transaction fees exist. It is about how those fees are structured and how much control you have over them.

BigCommerce still offers greater flexibility in choosing payment providers, which can be valuable for businesses with specific regional requirements or negotiated processing rates. Shopify prioritises a more standardised system. Less flexibility, but more consistency in how costs are applied and managed.

Neither approach is inherently better. But they lead to different financial outcomes depending on how your business operates. And this is where many comparisons stop too early. To get a clearer picture, the next step is to look beyond transaction fees and examine the full cost structure of both platforms.

BigCommerce vs Shopify pricing: beyond transaction fees

Focusing only on transaction fees creates a narrow view of platform cost. Most eCommerce businesses spend more on the surrounding layers than on the fees themselves.

Subscription pricing comparison

At entry level, both platforms start at a similar price point. The gap becomes visible as businesses grow.

The critical difference lies in how plan eligibility works. BigCommerce ties plans to annual GMV thresholds, and those thresholds changed in June 2026. The Core plan now caps at $30,000/year, down from $50,000 on the old Standard plan. Growth caps at $100,000/year, down from $180,000. Exceed the threshold and you are automatically upgraded, regardless of whether you need the additional features.

Shopify has no GMV caps. Merchants stay on their chosen plan until they decide to upgrade for features or lower processing rates. That cost predictability matters significantly during growth phases, when revenue is scaling faster than margin.

Payment processing costs

Both platforms charge standard card processing fees set by payment networks and processors, typically 2% to 3% depending on card type, geography, and volume. BigCommerce default rates through PayPal Braintree start at 2.59% + $0.30 per transaction on the Plus plan. For Shopify Payments rates in your market, check the Shopify pricing page directly as rates vary by region. Neither platform holds a structural advantage at standard volumes.

Hidden costs to consider

A more flexible platform may reduce costs in one area while increasing complexity in another. A more structured ecosystem may introduce app costs but reduce internal development effort. Transaction fees are only one layer. Total cost of ownership is shaped by subscription tiers, processing rates, app dependency, upgrade triggers, and development overhead combined.

Total cost of ownership: a practical comparison

Numbers become more useful when attached to a real scenario. Consider a merchant doing $500,000 in annual revenue, with a mix of payment providers across both platforms.

Card processing rates vary by provider, volume, and region. For current Shopify Payments rates in your market, check shopify.com/payments. For BigCommerce rates, check bigcommerce.com/essentials/pricing.

At first glance, BigCommerce and Shopify Payments land in a similar subscription range. The difference becomes visible when payment setup and plan upgrade risk are factored in. A merchant on Shopify Grow using Shopify Payments pays no platform transaction fee. The same merchant on BigCommerce Plus, routing orders through a gateway outside the embedded list, pays 1.0% on that GMV, and risks an automatic plan upgrade to $399/month if revenue crosses $180K.

What used to be a straightforward advantage for BigCommerce now depends entirely on how payment providers are selected. Merchants routing orders through Stripe or PayPal Braintree pay no Open Payment Provider Fee, and BigCommerce’s lower app dependency keeps total cost competitive. For those relying on regional or local gateways outside the embedded list, the equation has changed.

Platform choice is a financial decision, not just a technical one. Modelling that cost accurately before making a decision is where most teams underinvest. For brands already on or considering Shopify, Flatline’s TCO calculator breaks down the full cost structure so the numbers reflect your actual setup, not just the headline plan price.

It is worth noting that according to Shopify’s own platform comparison data, Shopify’s TCO is 31% better than BigCommerce on average, driven by 88% higher implementation costs and 32% higher platform fees on the BigCommerce side. These are Shopify’s figures, not independent research, but they point to a pattern that aligns with what we see in practice: the gap between headline pricing and actual cost tends to widen as complexity increases.

Ecosystem, flexibility, and scalability

Cost structure is one dimension of the decision. The other is what each platform enables operationally, and how that maps to long-term growth.

BigCommerce

BigCommerce operates on an open SaaS architecture, giving development teams deeper access to platform internals. Native B2B capabilities, including customer group pricing, quote management, purchase order workflows, and multi-storefront management, are built in at enterprise tier without requiring third-party apps. For businesses running parallel B2B and B2C channels, that native depth reduces integration overhead.

The trade-off is ecosystem breadth. Around 1,200 integrations in its marketplace and a smaller agency talent pool affect both implementation timelines and the availability of specialist support.

Shopify

Shopify’s primary strength is ecosystem density. Over 8,000 apps cover virtually every eCommerce use case, and the Shopify Functions framework allows checkout logic and discount structures to be customized at code level without modifying platform internals, across all plans, not just enterprise tier.

For brands scaling across geographies, Shopify Markets enables localised pricing, currency conversion, and regional checkout from a single admin. The Shopify partner ecosystem is the largest in eCommerce, which translates to faster implementation timelines and broader agency availability.

The trade-off is native feature depth. Capabilities built into BigCommerce by default often require paid apps on Shopify, introducing recurring subscription costs and integration maintenance.

A lower platform fee does not automatically mean a more efficient operating model. For most growth-focused eCommerce brands, Shopify’s ecosystem density and partner availability translate into faster execution and lower long-term operational overhead.

Which platform fits your growth strategy

For eCommerce brands focused on scaling, the platform decision comes down to one question: does your current setup support where your business is going?

Shopify’s combination of zero transaction fees via Shopify Payments, 8,000+ apps, and the largest partner network in eCommerce makes it the stronger foundation for brands that prioritise speed, margin stability, and long-term growth.

What this means for eCommerce profitability

The BigCommerce fee change signals something broader. Platform pricing is becoming more transparent and more conditional at the same time. The headline price is no longer the price.

There is also a dimension that rarely appears in cost comparisons: platform velocity. Shopify releases product updates twice a year through Shopify Editions, consistently shipping over 100+ product updates, performance improvements, and merchant tools with each cycle For eCommerce teams that depend on platform capabilities to execute their growth strategy, that pace of innovation is a structural advantage. It means less time waiting for features and more time using them.

At the same time, margin pressure in eCommerce is increasing across logistics, acquisition costs, and return rates. Platform fees are one variable in that equation, but they compound over time. A platform that costs less in subscription fees but introduces forced upgrades, app dependency, and transaction costs may produce a higher total spend over 24 months.

Platform selection is increasingly a strategic financial decision. Understanding how platform infrastructure translates into revenue performance is part of that. The Shopify customer events guide is one example of how platform-level capabilities connect directly to commercial outcomes.

Profitability is shaped by structure, not just percentages. A platform that aligns with your operating model will support margin stability over time. One that does not will gradually introduce friction, even if the initial cost appears lower.

Conclusion

The BigCommerce vs Shopify comparison has moved beyond a simple pricing debate. It is no longer about which platform appears cheaper on the surface. It is about how each platform structures cost, supports growth, and impacts profitability over time.

For most eCommerce brands focused on growth, Shopify provides a more structured ecosystem, faster execution, and more predictable scaling. The combination of zero transaction fees via Shopify Payments, 8,000+ apps, and the largest partner network in eCommerce makes it the stronger long-term foundation for brands that prioritise speed and margin stability.
