# 2024-10-07: CE - External fees

### Overview

In B2B contexts, there may be instances where additional fees are required for specific purchases from external sources. For instance, certain purchases may necessitate the addition of fees for specialized shipping, packaging, larger size, or freight costs, which would be included in the overall product price. If you are seeking a solution for integrating your custom fees with the Emporix Commerce Engine, we have a ready-made option for you. Commerce Engine allows you to add externally sourced fees at the cart level.
