Integration Flexibility: Connecting Systems with Open Source

21. Payment processing standardizes around 2.9% + $0.30 fees

Major payment processors including Stripe and PayPal charge 2.9% + $0.30 per transaction as baseline rates. These fees apply regardless of platform choice, though some proprietary platforms add additional transaction fees on top of processor charges.

Swell charges 0% transaction fees on external payment gateways—a significant advantage compared to platforms like Shopify that add 2% fees unless merchants use their proprietary payment solution.

Seamless Workflows: Integration Capabilities Across Platforms

Modern ecommerce requires connections to numerous business systems:

• Email marketing — Klaviyo, Mailchimp, Omnisend
• Fulfillment — ShipStation, third-party logistics providers
• Tax compliance — Avalara AvaTax, TaxJar
• Customer service — Helpdesk and support platforms

• Local payment methods — Region-appropriate payment options

Swell supports 230 currencies with explicit pricing rules and content localization across 170 languages. Tax integration with Avalara and TaxJar ensures compliance across jurisdictions without custom development requirements.

Merchant Control & Data Ownership with Open Source Solutions

30. Companies over $5 billion revenue represent 51% of platform spending

Enterprise organizations with revenues exceeding $5 billion account for 51% of total platform expenditure. This concentration demonstrates that large enterprises prioritize robust platform capabilities over cost minimization.

31. Mid-market companies represent just 0.4% of spending despite massive numbers

While over 4.2 million companies fall into the $1M-$10M revenue bracket, they contribute only 0.4% of total platform spending. This disparity highlights how mid-market merchants often operate on constrained platform budgets relative to their actual needs.

Your Data, Your Rules: The Power of Ownership

Data ownership represents a core advantage of open source and API-first platforms. Key ownership considerations include:

• Full data export — Complete access to customer, order, and product information
• API accessibility — Programmatic access to all platform data
• Custom field creation — Business-specific data structures without limitations
• Migration flexibility — Ability to move platforms without data loss

Swell's API-first design means merchants access the same Backend API that powers Swell's own dashboard and checkout. This architectural approach ensures no functionality is hidden behind proprietary interfaces—merchants can replicate, extend, or replace any native feature.

For B2B and wholesale operations, this control enables customer-group-based pricing, custom approval workflows, and integration with existing ERP systems without sacrificing platform flexibility.
