BOYY US review for Zonos Duty and Tax

I have been looking for an app that will dynamically apply the appropriate taxes and duties to e-com orders so that my customers do not have to pay these upon receipt (meaning easier and hassle-free delivery). Zonos is literally the only thing I have found on the market that does this. They worked with me on a very tight timeline to implement the app and even customize my checkout page across multiple stores. Highly recommended - there's just no comparison to trying to keep static tables for tax and duties calculation.
