This app is phenomenal - we couldn't live without Decimal. It's unbelievably flexible and automated. Changes get done without any effort on our part :)

Save yourself the agony of trying other shipping calculation apps. Decimal is all you need, folks!

Decimal is badass. Love their concept of "no user interface"...hassle-free, fast and precise. We could not live without this app.

Thank you, Shopify, for introducing us to Decimal!

We are a Shopify Plus store that sells high tech touch screens and camera modifications. Shipping cost is our second largest expense item, and is extremely complex to calculate. We ship some products from US and others from China. To complicate matters further, the Chinese warehouse cannot ship to some countries directly, so those orders needed to be routed via US. Furthermore, our shipping rate tables vary significantly between products, making accurate cost calculations nearly impossible. But somehow Decimal is able to do so effortlessly, and oh so accurately.

Imagine what happens when an order contains items that are to be shipped from our US warehouse as well as from the China facility and the buyer is located in a country that does not accept product directly from China!

Without Decimal doing all the hard work for us, we’d be in trouble!

But wait, there’s more….

The best part about this app is that there is nothing for us to set up. We simply tell the Decimal team what we need done and it just gets done, immediately. So easy! No messing around with user interfaces that suck - hard to understand or mostly plain incapable to handle what we need done.

Decimal is the most sophisticated system we have come across. We are huge fans of this app.

We are a Shopify 'Plus' store that manufactures cameras for use in specialized industries such as aerial surveys and geo-imaging.

Decimal has been a life saver for us. The precision and speed with which the system calculates shipping rates is spectacular.

We tried the other apps and none of them come close to the sophistication of Decimal. ***** Five Stars! *****

The most powerful shipping rates app!

We were amazed at the speed and accuracy with which our shipping rules and rates were implemented.

And since there's no user interface, we didn't have to do any setup work! Just sit back and let the Decimal team take care of everything!

Finally - a solution to our shipping woes!

Given the nature of our cabinetry products, it has been difficult to find a program to correctly ascertain the correct shipping costs. Many of our products are large, bulky and are rated dimensionally versus just by weight. The calculated freight has either been too high or too low with both situations causing us to lose. When the freight calculates too high the cart is abandoned and when the freight is calculated too low, it erodes our profit, often making the sale completely unprofitable.

We have been searching for a solution since our store opened and after several failed attempts with our solutions, we came across Decimal and discovered there is a viable shipping calculator that actually works. The algorithm accurately predicts the exact composition of the boxes that an order would be shipped in. The precision of the calculations allows us to be in full control of our shipping costs. It even assists us by providing packing instructions so our warehouse knows what goes in each box.

With Decimal powering our checkout pages, we are finally able to charge our buyers just the right amount for shipping costs.

This app slashed our abandonment rate!

As soon as we installed the Decimal system, an amazing thing happened - our cart abandonment rate plummeted! Our customers are thrilled that they can pinpoint their receive dates and plan their oyster parties weeks in advance, knowing that fresh oysters will arrive exactly on the day they want them!

Decimal powers our Shopify store’s Shipping Rate calculations as well as our Pinterest channel, which is integrated into Shopify. As a result, Decimal's shipping rate algorithm can also be seen by anyone checking out via Pinterest's 'Buyable' pins!
