WordPress vs. Shopify TCO Analysis for B2B: The Real 3-Year Cost

The Number Most Platform Comparisons Get Wrong

Platform comparisons typically compare subscription costs and feature sets. Total Cost of Ownership (TCO) includes all costs over a multi-year horizon: licensing, hosting, development, maintenance, integration, and the opportunity cost of downtime and technical debt.

For B2B businesses evaluating whether to build their ecommerce or product catalog on WordPress (WooCommerce) vs. Shopify, the TCO analysis over 3 years typically tells a different story than the subscription cost comparison.

Defining the B2B Use Case

This analysis targets B2B businesses with these characteristics:

• Selling products or services to other businesses (not D2C)
• Requiring custom pricing per customer or customer group
• Needing quote workflows or approval processes
• Integrating with CRM (HubSpot, Salesforce) and ERP systems
• Serving a mix of online self-serve and sales-rep-assisted purchasing

This use case has specific platform requirements that change the cost calculus.

WordPress (WooCommerce) TCO for B2B

Year 1 costs:

• Hosting (managed WordPress, e.g., WP Engine Business): €2,400/year
• WooCommerce core: €0
• B2B-specific plugins (B2BWoo or similar for custom pricing, quote management): €300-600/year
• Development (custom B2B workflows, CRM integration, ERP sync): €15,000-40,000
• SSL, security plugins, backup solution: €500-1,000/year
• Theme (custom or premium): €5,000-15,000 (one-time)
• Year 1 total: €23,200-59,000

Year 2-3 costs (annual):

• Hosting: €2,400/year
• Plugin licenses (renewals): €300-600/year
• Security maintenance, plugin updates, PHP version maintenance: €3,000-8,000/year
• Feature development and bug fixes: €5,000-15,000/year
• Year 2-3 annual: €10,700-26,000/year

3-year WooCommerce total: €43,600-111,000

Shopify (Plus) TCO for B2B

Platform context: Shopify Plus is required for native B2B features (Company accounts, custom pricing, payment terms). At $2,300/month minimum.

Year 1 costs:

• Shopify Plus subscription: €26,000/year (€2,166/month)
• Custom development (B2B portal configuration, CRM integration, ERP sync): €8,000-20,000
• Apps (review, loyalty, analytics): €2,400-6,000/year
• Year 1 total: €36,400-52,000

Year 2-3 costs (annual):

• Shopify Plus subscription: €26,000/year
• Apps: €2,400-6,000/year
• Minor development and maintenance: €2,000-5,000/year
• Year 2-3 annual: €30,400-37,000/year

3-year Shopify Plus total: €97,200-126,000

The Critical Variables That Change the Analysis

At face value, WooCommerce is cheaper over 3 years in most scenarios. But three variables frequently reverse this:

Development team availability: If you don't have an in-house WordPress developer, your WooCommerce maintenance cost (security updates, plugin conflicts, custom feature development) runs through an agency at €100-200+/hour. This pushes real-world WooCommerce TCO significantly higher than the estimates above.

Uptime and reliability cost: WooCommerce downtime events (server issues, plugin conflicts, hack recovery) have direct revenue cost. For a B2B business doing €500,000/year GMV, a 24-hour outage costs €1,370 in lost revenue plus development time to fix. Shopify Plus's 99.99% uptime SLA and managed infrastructure eliminates this risk category.

Time-to-feature: When a B2B buyer requests a feature (bulk ordering, quote approval workflow), how long does it take to implement? On Shopify Plus, many B2B workflows are configurable without development. On WooCommerce, many require custom plugin development. The development backlog cost is real but rarely counted in TCO models.

ERP integration complexity: For businesses requiring SAP, Oracle, or Microsoft Dynamics integration, Shopify Plus has a larger ecosystem of certified integration partners and pre-built connectors. WooCommerce ERP integrations frequently require bespoke development.

The Decision Matrix

WooCommerce makes financial sense when:

• You have an in-house WordPress/PHP development team
• Your GMV is below €1M/year (Shopify Plus subscription is a high fixed cost)
• Your B2B workflows are relatively simple and can be handled with off-the-shelf plugins
• You need deep custom CMS functionality alongside ecommerce

Shopify plus makes financial sense when:

• You don't have in-house development capacity for ongoing WordPress maintenance
• Your GMV is above €2M/year (the Shopify Plus subscription is a smaller percentage of revenue)
• You need reliable uptime for enterprise B2B buyers who expect consistent availability
• You're expanding internationally and need Shopify Markets' multi-currency/multi-language capabilities
