Absolutely amazing. Does everything it says and more. Shows cool analytics and the built-in AI Code editor is great. Good docs and overall great experience. Wish they made more apps. Thanks for making this app!!!!

JsRates is the only way to go. I have tried so many different apps, from cheap to very expensive, and they all have so many little shortcomings and flaws. You see, our store has very complex shipping needs. In stock, back order, made to order, drop-ship, LTL freight. You name it. And I spent years trying to find the right software but always feeling like I was putting a band aide on the problem but never solving it. This all changed with JsRates. Using JavaScript to customize the rate process is honestly the only way to go, and this software is the perfect solution to do so. Since I'm not a developer, Behailu was very helpful in getting set up and running. And then from there I have been able to use AI to modify the code as needed for further tweaks. I can now do just about anything that I want when it comes to how shipping is calculated and quoted to the customer at check-out. It's fantastic and I would recommend to anyone JsRates as a very reasonably priced solution with unlimited flexibility. I honestly don't know what I would do without it now that I have fully integrated it into our tech. stack.

Developer repliedThank you so much for this incredible review! I’m really glad JsRates has finally given you the flexibility you needed, and it’s been a pleasure helping you get everything set up. Appreciate you! 🙏 Show more

JsRates is a hidden gem. We have tried and tested so many shipping apps over the years and JsRates is by far the most flexible and powerful. We use a blend of shipping carriers that have different cut off times and delivery schedules (they only deliver to a certain postcode once per week for example) and using JsRates we able to deploy shipping estimates at checkout that are accurate and dynamic. Until I discovered the app I assumed it was an unsolvable problem on shopify checkout. It takes some persistence to get it working but Behailu is extremely responsive and generous with his time and we are stoked with the result. Highly recommended.

Developer repliedThank you so much for the amazing review! It means a lot to know the flexibility and precision we built into the app is making a real difference. Appreciate your kind words; it's been a pleasure working with you! Show more

Highly recommend for custom shipping price calculations. I needed extra shipping cost variables added for shipping of custom length products by the millimetre (mm) and also additional costs for shipping to different States and Territories within Australia, plus the solution would work well for worldwide shipping too. I received excellent support and setup of the app to calculate custom postage rates. Very fast responses from the developer. Very happy and very pleased customer. Thank you.

Outstanding Custom Shipping Solution with Exceptional Support We have been using JsRates for managing our shipping logic, and it has truly transformed our fulfillment process. One of the most significant challenges we faced was the need to exclude specific U.S. ZIP codes from shipping options due to logistical constraints. JsRates allowed us to seamlessly implement these complex shipping restrictions with precision, saving us from potential shipping errors and unnecessary costs. The flexibility JsRates offers in tailoring shipping rules using JavaScript is unparalleled. We were able to customize every aspect of our shipping rates, ensuring that the solution perfectly aligned with our business needs. Whether you're dealing with distance-based, product-specific, or customer-based rules, JsRates can handle it all effortlessly. What really sets JsRates apart, however, is their exceptional support team. They provided fast, knowledgeable assistance every step of the way, ensuring we were up and running in no time. Their expertise in both the app and broader shipping logistics made a real difference, and they went above and beyond to ensure our custom shipping logic was fully operational. If you’re looking for a robust and flexible shipping rate solution that can handle even the most complex scenarios, I highly recommend JsRates.
