Get Started

The Shopify Plus vs BigCommerce decision narrows to four things for most enterprise ecommerce teams: what you pay in transaction fees, how much control you have over checkout, how deep the B2B feature set goes, and how large a catalogue you need to manage.

Everything else - the ecosystem, the brand recognition, the headless options - is meaningful context. But the four variables above are where stores with significant GMV, complex checkout requirements, or real B2B operations discover that one platform fits their situation and the other does not.

This guide resolves that decision with 2026 pricing reality, honest B2B and checkout capability assessments, and a clear decision matrix for the common store archetypes.

Pricing and Fees: The Number That Changes the Decision

Shopify Plus Pricing

Shopify Plus pricing has two components. The base platform fee starts at $2,300/month (billed annually) or scales to 0.25% of monthly revenue once GMV exceeds $800,000/month - whichever is higher. At very high GMV, the revenue-based fee can become significant.

The more consequential cost for many stores: transaction fees. If you use Shopify Payments (Shopify's native payment processor), transaction fees are 0%. If you use a third-party payment gateway - PayPal, Adyen, Braintree, Stripe, or any other processor - Shopify charges an additional fee of up to 0.2% per transaction on Plus.

For high-volume stores with outside payment processors, this fee compounds quickly. A store processing $10M/month through Adyen pays $20,000/month in Shopify transaction fees on top of the platform fee and the gateway's own processing fees.

BigCommerce Enterprise/Performance Pricing

BigCommerce's enterprise pricing is custom and requires contact with their sales team. BigCommerce's Performance plan (their below-enterprise tier for higher-volume merchants) has published pricing.

The critical difference from Shopify: BigCommerce charges no transaction fees regardless of which payment gateway you use. Adyen, Braintree, PayPal, Stripe - all carry zero additional BigCommerce fee. For stores with negotiated gateway rates or specific payment processor requirements, this is a direct cost advantage.

TCO Scenarios

Store profile	Shopify Plus annual cost	BigCommerce Enterprise annual cost
$2M/month GMV, Shopify Payments[cite: 14]	~$27,600/year platform[cite: 14]	Custom - typically 25, 000 – 50,000/year[cite: 14]
$2M/month GMV, Adyen gateway[cite: 14]	~$27,600 platform + ~$48,000 transaction fees = ~$75,600/year[cite: 14]	Custom platform fee only - no transaction fees[cite: 14]
$10M/month GMV, Shopify Payments[cite: 14]	Platform fee scales with revenue[cite: 14]	Custom - negotiate based on GMV[cite: 14]
$10M/month GMV, third-party gateway[cite: 14]	Platform + 0.2% = very significant transaction fee[cite: 14]	Platform fee only[cite: 14]

Cost estimates are illustrative. GMV thresholds and fee structures are subject to change. Verify current pricing and fee structure directly with both platforms before budgeting.

The conclusion is clear: for stores committed to Shopify Payments, the transaction fee difference is minimal. For stores with outside payment processors - particularly those with negotiated rates or regional gateway requirements - BigCommerce's zero transaction fee model is a meaningful cost advantage that warrants serious evaluation.

Checkout and Payments

Shopify Plus Checkout

Shopify's checkout is among the best-converting in ecommerce, optimised continuously by Shopify across billions of transactions. Shop Pay accelerates checkout for returning customers across the Shopify network. The conversion data behind Shopify's checkout is genuinely strong.

The customisation model for Shopify Plus: Checkout Extensions allow modification of the checkout flow without editing the underlying checkout code. You can add custom fields, payment method conditions, dynamic discounts, and post-purchase upsells - all within the Extensions framework.

What Checkout Extensions cannot do: fundamentally restructure the checkout layout, deeply modify the payment method display, or implement checkout flows that diverge significantly from Shopify's standard model. For most DTC brands, this is not a limitation. For stores with complex checkout requirements - custom B2B payment terms, specific checkout flows for different customer segments, heavily customised validation logic - the Extensions model may be constraining.

BigCommerce Checkout

BigCommerce's checkout is fully open: the HTML, CSS, and JavaScript of the checkout can be modified directly. You can also replace the native checkout entirely with a custom-built checkout using the Checkout SDK, connecting to any payment processor via the Payments API.

For stores that need checkout as a differentiator - unusual financing options, complex multi-step checkout flows, integration with procurement systems, or checkout UX that deviates significantly from the standard model - BigCommerce's open checkout is a decisive advantage.

The trade-off: full checkout ownership means full checkout maintenance responsibility. A custom checkout is a codebase that must be tested against browser updates, security patches, and platform changes.

B2B and Multi-Storefront

Shopify Plus B2B

Shopify Plus B2B covers the core B2B requirements that most wholesale and hybrid DTC/B2B brands need:

Company accounts with multiple contacts
Custom pricing per company or per customer segment
Payment terms (net payment, purchase orders)
Volume pricing and quantity breaks
Draft orders created by sales teams
B2B-specific storefront experience (separate storefront with B2B-only access)

For brands with moderate B2B complexity - a wholesale channel alongside DTC, a limited number of B2B customers with negotiated pricing - Shopify Plus B2B is sufficient and significantly easier to configure than a full B2B platform.

Where Shopify Plus B2B shows its limits: very large B2B customer bases with complex tiered pricing, quote workflows across multiple product lines, integration with procurement systems, and approval workflows for large purchase orders. These requirements push toward BigCommerce B2B Edition or Adobe Commerce.

BigCommerce B2B Edition

BigCommerce B2B Edition is the most mature native B2B feature set in the SaaS ecommerce market below Adobe Commerce. It covers:

Multi-storefront from a single admin (separate storefronts for different brands, regions, or customer segments)
Granular price list management (multiple price lists, customer-group-level pricing, contract pricing)
Purchase orders and payment terms with configurable approval workflows
Quote management with line-item negotiation
Sales rep accounts with customer account management
Invoice management and net terms

For organisations where B2B revenue is the primary channel or is structurally complex - distributors, manufacturers, wholesalers with contract pricing - BigCommerce B2B Edition addresses requirements that Shopify Plus B2B does not fully cover without significant app or custom development.

Multi-Storefront

Shopify Plus handles multi-storefront through expansion stores - separate Shopify store instances under the same Plus contract, with shared payment and shipping settings but separate catalogues, themes, and domains. Each expansion store is managed separately in its own admin.

BigCommerce's multi-storefront model allows multiple storefronts managed from a single admin, sharing a single catalogue and customer database. Product assignments, pricing, and content can be configured per storefront from one place. For organisations managing multiple brands or regional storefronts with overlapping catalogues, this architecture reduces operational overhead significantly.

Apps and Ecosystem

Shopify's app ecosystem is the largest in ecommerce - over 8,000 apps covering every use case from review platforms to loyalty programmes to inventory management to ERP connectors. For almost any functional requirement, a Shopify app exists, is actively maintained, and has a substantial user base and review history.

BigCommerce's ecosystem is smaller but growing. The certified partner programme and the BigCommerce App Marketplace cover the most common use cases. For standard integrations - email platforms, loyalty, reviews, shipping - BigCommerce has solid options. For niche requirements, the app may not exist or may be less mature than the Shopify equivalent.

The ecosystem difference matters most for teams that rely on apps rather than custom development for functionality. If your current app stack is heavily Shopify-native, a BigCommerce migration requires replacing or re-evaluating every app. Factor this into the migration scope.

Headless Options

Shopify Hydrogen

Hydrogen is Shopify's React-based headless framework, with Oxygen as the hosting layer. Hydrogen gives development teams a full-stack React application with Shopify's Storefront API as the commerce back-end - product data, cart, checkout, customer accounts. The Shopify checkout is accessed via Shopify's hosted checkout rather than a fully custom implementation.

For teams that want headless front-end performance and flexibility with Shopify's commerce back-end and ecosystem, Hydrogen is the path. The constraint: checkout remains within Shopify's hosted model, with Checkout Extensions for customisation.

BigCommerce Catalyst

Catalyst is BigCommerce's Next.js reference architecture for headless commerce. It provides a starting point for a Next.js front-end with BigCommerce's GraphQL Storefront API as the back-end. The checkout, via the Checkout SDK, can be fully customised or replaced.

For teams that want headless flexibility including full checkout ownership, Catalyst on BigCommerce is the stronger headless path. The trade-off: a smaller ecosystem and less prescriptive tooling than Shopify's Hydrogen/Oxygen combination.

Migration Notes

Migrating to Shopify Plus

Shopify Plus migrations are well-supported by the Shopify Partner ecosystem. The Magento to Shopify migration guide covers the Magento-specific data challenges. For the broader ecommerce replatforming process, the ecommerce replatforming guide covers the scoping and data migration framework that applies regardless of destination platform.

The Shopify-specific migration considerations: data transformation for products with complex attribute sets, app migration from the existing platform to Shopify equivalents, and the checkout customisation investment for stores that need significant checkout modification.

Migrating to BigCommerce

BigCommerce migrations are less well-represented in the agency ecosystem than Shopify migrations, which means fewer off-the-shelf migration tools and a smaller pool of experienced migration partners. Factor additional scoping and development time into any BigCommerce migration estimate.

The BigCommerce-specific migration considerations: catalogue migration for very large product catalogues with complex options and variants, multi-storefront architecture planning if multiple storefronts are being consolidated, and B2B customer data migration with associated pricing and permission structures.

For migration services evaluation regardless of destination platform, the Shopify migration services guide covers the evaluation criteria and red flags that apply to any ecommerce migration partner.

Frequently Asked Questions

Which Is Cheaper, Shopify Plus or BigCommerce?

It depends on your payment gateway. For stores using Shopify Payments, Shopify Plus is cost-competitive. For stores using third-party payment gateways, Shopify Plus charges up to 0.2% per transaction - at $5M/month GMV that is $10,000/month in additional fees. BigCommerce charges no transaction fees regardless of gateway. Model your specific GMV and gateway combination against both platforms' pricing before deciding.

Is Shopify Plus or BigCommerce Better for B2B?

For moderate B2B complexity (wholesale channel alongside DTC, standard net payment terms, volume pricing), Shopify Plus B2B is sufficient and simpler to configure. For complex B2B (contract pricing across a large customer base, quote workflows, approval workflows for large orders, very large number of B2B accounts), BigCommerce B2B Edition has deeper native capability.

Does BigCommerce Charge Transaction Fees?

No. BigCommerce charges no transaction fees regardless of which payment gateway you use. This is a direct cost difference from Shopify Plus, which charges up to 0.2% per transaction when using third-party payment gateways.

Which Has a Better App Ecosystem?

Shopify Plus has the largest ecommerce app ecosystem by a significant margin - over 8,000 apps. For teams that rely on apps for core functionality, Shopify's ecosystem offers more options with more review history. BigCommerce's ecosystem is smaller but covers the most common use cases.

Can BigCommerce Handle a Large Catalogue?

Yes. BigCommerce's enterprise plans remove variant limits and support very large catalogues with complex product options. BigCommerce's catalogue and multi-storefront architecture is generally stronger than Shopify's for complex catalogues shared across multiple storefronts.

Which Supports Headless Ecommerce Better?

Both support headless commerce - Shopify via Hydrogen/Oxygen (React-based, Shopify-hosted), BigCommerce via Catalyst (Next.js reference architecture). Shopify's headless path keeps the hosted checkout with Checkout Extensions. BigCommerce's headless path allows full checkout ownership and customisation via the Checkout SDK.
