Upcharge Surcharge Fee Tariff

Installed this app needing a solution for new tariff taxes/surcharges that now apply in varying amounts to select products (not all) we sell.
The UI for this app is good and setup was straightforward. It would allow me to setup different % based or $ amount surcharges based on a variety of conditions, which suits our needs well. Basic setup was easy.
There was some delay (minutes) before the first fee I created started showing up, but that was ok and once it showed up further changes worked instantaneously.
Our % based fee for a specific product looked good on the Checkout page - the app adds a product, which is bundled with the applicable sale item and gives a clear picture of what the fee is for and amount in both %s and $s.
Very dissatisified with presentation on the Cart page. We are using Pursuit theme and it added multiple CartItem__Property rows to the product listing in the cart, which would be fine except they contained div and parameter names (code) and were not user friendly. I was unable to find a solution for this on my own and could not wait for dev team to respond.
There are some advanced setup options with no info or help available in the UI or app documentation, and I suspect it was these options that were causing our problems. I tried adding various divs to the fields but seemed to have no effect. While we wanted to use the required hidden fee option, I was not able to get any options to work (radio button, checkbox, drop down, etc.). Perhaps it was a compatibility issue with our theme (pursuit).
The app is pretty invasive by adding exclusion conditions to numerous (but not all?) Product Collections in our store, which were NOT removed when I uninstalled and had to be removed manually.

Update: The team responded very thoroughly and responded to the issues I experienced.
Private line item properties are used to store and display detailed information about the surcharges during checking, which are supposed to be hidden from customer-facing views according to Shopify guidelines. So the fact that they are being displayed is an issue with the Pursuit theme we are using. A small code snippet can resolve this.
The conditions that were displaying in the collections were a legacy feature that is no longer needed and was removed so future users won't have this issue.

Downloaded and added this app after having issues with another app not loading. Did have a singular issue that was resolved within a few hours and no longer have the issues. I am using this app to add fees for handling and service fees to pass onto the customer. It's been a breeze to use. I do recommend this app for anyone needing this service.

We use UpCharge to help pass along the credit card fees that we are charged. At one point I needed product support and their team was quick to respond and resolve the issue. I received a response and answer within minutes of emailing them.

App could be better and there is no scope for enhanced features or customisable options.
In terms of adding fees and surcharges, the function does not do well in shopping carts and customers can delete the option which defeats the purpose in the first place.

It stops working randomly, causing a blocked white screen. Lost thousands of dollars in sales. Even after support fixed the issue once. Cant risk using this app anymore.

A simple and clean app for that works as it should – perfect for small cart add ons. It didn't install and seamlessly as I would have hoped, but I'm guessing that was more of a theme issue then their app. Angie was great at getting me setup and the module placed exactly where I wanted.

The Order Surcharge & Product Fees app works well for us. We did hit a theme incompatibility issue but their dev team was quick to rectify the situation.

Great helper
