Upcharge Surcharge Fees Tariff

We use this app to add a cart fee during checkout. It works quite well and the support team is super responsive! I wish there was a little more opportunity for customization (our cart fee needs more details to describe it and there is a strict character limit). The cart fees work by generating products, which can seem a little confusing on the backend, but the benefit is that the cart fee shows up everywhere we need it to (work orders, confirmations, etc.). Overall would recommend this for a solution to cart fees and we have definitely seen this app pay for itself with the increased revenue.
