In this article, we’ll provide a detailed breakdown of how we calculate the additional monthly costs (TCO) associated with B2B eCommerce platforms and how these impact site performance (e.g., loading time increases). This information complements a previously presented slider, which visualizes how the number of add-ons, integration partners, and market areas affects total cost.
Please note: The estimate is based on a sample case where the B2B eCommerce store operates internationally. Actual costs vary depending on business volume, the scope of integrations, and service level.
How traditional eCommerce platforms limit B2B growth
Single market
Multiple markets
Global scalability
Traditional monolithic platforms like Shopify, Magento, or WooCommerce are built for single-market use and rely heavily on add-ons for payments, invoicing, logistics, B2B pricing, compliance, and user management. This leads to increased system complexity, slower performance, and growing reliance on external integration partners — especially when ERP, CRM, or PIM systems are involved.

1. Cost and speed impact: How we measure it
The table below outlines typical add-ons used by enterprise-level B2B eCommerce platforms. Costs consist of monthly license fees or transaction-based charges. In addition, each add-on typically includes its own loading script (JavaScript, CSS), which increases overall page load time.
The table below outlines typical add-ons and performance overhead in other platforms (such as Shopify, Magento, WooCommerce – where core features are often implemented using separate extensions).
Add-on / plugin
Cookie banner / GDPR (Cookiebot, OneTrust)
~80–150 €
+200–400 ms
Review app (Trustpilot, Yotpo)
~300–800 €
+100–300 ms
Search tool (Klevu, Algolia)
300–800 €
+100–300 ms
International sales (Weglot etc.)
~180–300 €

+100–300 ms
Bulk ordering from list view, B2B Bulk Order
~50–150 €
+50–100 ms
Request for quote functionality (cart2quote)
~100–300 €
+100–300 ms
Total: 14 items
~1790–4880€
1.35–3.5 seconds
Note! These figures are indicative. Some services charge a fixed monthly fee, while others are based on traffic volumes or transaction quantities. Load time impact is especially significant when each add-on loads its own script separately.
2. Assumptions and Sources
The cost and performance estimates are based on the following factors:
Published pricing: Many add-ons (e.g., Weglot, Klaviyo, Cookiebot) publish tiered pricing that increases with traffic and domain volume.
Typical enterprise B2B use cases: Multilingual support, large product catalogs, customer-specific pricing, and payment terms often require numerous add-ons.
Cumulative load impact: Each add-on introduces rendering delays, which can cumulatively reach up to three seconds.
Practical project experience: The ongoing maintenance costs of ERP, PIM, payment, and logistics integrations can range between €300–2,000/month.
3. Why these are estimates
Business volume: The number of orders, users, and SKUs directly influences add-on pricing.
Number of domains: Multiple country domains significantly increase licensing costs and performance overhead.
Customization needs: B2B add-ons often require configuration and development, leading to additional project-specific costs.
Platform-specific differences: Shopify, Magento, and WooCommerce vary in how add-ons are priced and what features are included by default.
