Why do you need a Magento 2 Surcharge Extension, incurring additional costs?

Up to 55% of abandoned purchases are caused by unexpected additional costs at checkout.
If your shop sells pipes, profiles, bar stock, or bulky products, you'll often incur surcharges for cutting or handling. Without transparently displaying these costs, you'll lose customers every day—and receive negative reviews.

STM Surcharge This solves this problem: Display additional costs directly on the product page, automatically calculate category-based surcharges, and present mixed baskets transparently.
The result: fewer abandoned purchases, more trust, and measurably higher conversion rates.

How does the Magento 2 Surcharge Extension automatically calculate additional costs?

No more manual calculations: The extension automatically distinguishes between three scenarios — and always calculates the shipping costs correctly, regardless of how the shopping cart is composed.

  • Category products only (e.g., pipes, profiles): Only the individually configurable cutting and additional costs will be charged.
  • Standard products only: Normal shipping costs apply — above a freely definable threshold (e.g. €100) shipping is automatically free.
  • Mixed orders: Combinations of category products and standard goods are displayed with transparent combination costs.
  • Country restrictions: Additional costs may be limited to certain countries (e.g., Germany, EU).
  • Fully automatic calculation — no manual price adjustment required per order

💡

How can additional costs be displayed transparently on the Magento 2 product page?

Every hidden cost costs you conversions. That's why a prominent notice with its own info icon informs your customers about any additional costs directly on the product page—before they even reach the shopping cart.

  • Dynamic information text with price placeholder — shows the exact surcharge per product
  • Custom info icon for immediate visual recognition
  • Fully customizable: Colors, font sizes, spacing and borders can be configured via the admin settings.
  • Notice only visible on affected products — no unnecessary information overhead
  • responsive Design — optimized display on desktop, tablet and smartphone

  • Price for extra costs — individually configurable for each configuration
  • Standard shipping costs for regular products
  • threshold for free shipping (e.g. from €100)
  • Country restriction — e.g., only Germany or the entire EU
  • Theme Options: Colors, font sizes, spacing and icon for the product information
  • Dynamic text with price placeholder for the additional cost information

🛒

How are additional costs correctly displayed in the Magento 2 shopping cart?
