ShipperHQ: Shipping & Checkout

The ShipperHQ app allows us to offer our customers specific shipping options and carriers at checkout based on what is in their cart. We have a wide variety products that vary greatly in size and price. This app allows us to set up complex rules for our shipping options. We've not found any other Shopify app that allows us the same functionality. It's also been very reliable, without any downtime in the 5 years we've used it. This is very important in an app on the checkout page!
The ShipperHQ support team is very responsive and always helpful. Recently we switched to a new LTL freight carrier. The ShipperHQ team guided us through adjusting our settings to add the carrier. When we ran into difficulty the support representative, Michael, scheduled a meeting and walked us through adjusting our settings until we got the result we were looking for.

We use ShipperHQ across all of our platforms and the stability and customer support is amazing.

I would definitely reccomend.

I would give more stars if I could. Shipper HQ is both an incredibly powerful and flexible app for calculating shipping and delivery costs, their support is the absolute best I've seen. You can not go wrong with this product and the team that backs it up!!!

To speak to the reviews that indicate a steep learning curve - first, I would say that it can appear intimidating, but if you take a breath and follow the steps in the help docs one by one, it's quite easy to set up. AND if you get stuck, that's when their service can really be helpful in figuring out what you missed (I speak from experience. Every problem I've had has been something I missed that was right there. They never make me feel badly about it, but just solve my problem)
As to shopify and shipper HQ, I can speak to that too, because I used Shipper HQ on a different platform previously, and that platform would record any errors in going through shipping. Shopify doesn't do that, and I would put that on shopify not shipper HQ. Regardless of the lack of error codes from the website, Shipper HQ has helped me out of TWO jams that I got myself in, and in WAY under 24 hours too!!
Don't listen to the negative reviews. They don't represent what this company stands for, (which should be obvious based on the responses from the App team.)
