NOTCH® review for Tax & Duty King – Import Fees

Jan. 6, 2026

VAT & Duty Calculator was incredibly easy to install and worked perfectly straight away. The customer service and support are genuinely first class — fast, helpful, and knowledgeable. The app itself performs brilliantly, giving our customers clear and detailed information about potential import costs. This transparency has noticeably improved our conversion rate and overall customer satisfaction. A fantastic app that we highly recommend.
