UpCharge Fees Addons Surcharge

This app works great for us and also gives us flexibility in how we charge different types of fees, whether it's a percentage fee, flat fee, hidden fee or another option. Support is amazing for both technical help, answering general questions and giving tips. Update: Unfortunately this app ended up being rather unreliable in the long run. If you have a small store, this might work. However, for larger stores the consistency of the fee being applied is spotty. Also, the way the app adds the fee is not ideal with products needing to be created each time.
