Excellent customer service. We had an issue in the coding that the app was not making a fee show up correctly in the cart. Javid and the team found the issue, sent me the custom CSS, and guided me where it needed placed and solved our issue. I wish more companies would have the kind of service that was provided to us like UC Lab LLC.

The team was extremely helpful when the app wasn’t working as intended and kindly provided a refund for the period when we experienced the issue. Everything is now working as it should for our store, and we’re very happy with the app!

We found this app was not suitable for a Non Shopify Plus store because it only allows for IP Country location. So an order placed in one country for delivery in another will not apply the tariffs to delivery country. And orders placed through a Starlink connection often get USA fees charged no matter what country they are being delivered to. App would probably be fine for Shopify Plus Stores where you can set up checkout shipping address as a condition.

The app has been working perfect for months and when we had a website upgrade, there was a little glitch, but the UC Lab development team jumped right on it and got it fixed. Very pleased.

Work on Upcharge Surcharge Fees Tariff?
Any amount puts this listing above the review-data order, on the board and in Selling products. Every amount and every click is printed in public. Paying also opens a private page for this listing – that is where the badge for your site, the share card and your deal live. Everything you can do here, including what money cannot buy and how to get this listing corrected or taken down.
Not ready to pay for anything? Take the badge – it shows this listing’s live rank on your own site, it is free, and it always was.
Claiming is free and it shows: the listing turns gold in every list – the same highlight a paid card carries – with a Claimed badge, in the exact place its reviews put it. It also earns the only followed link on this site: a claimed listing that has paid nothing links to its own website dofollow – a paid placement never does, because a link that was paid for is an ad. Claiming moves nothing.
