Great System, Somewhat Complicated - We have been using ShipperHQ for about a year now and it works really well when it's properly setup. It can be complex to setup if you want to trace shipping very accurately and if you sell a wide range of sizes of products (i.e. envelope to 120 lb DIM). I do recommend using it though, even with the complexities. It can save you a lot of money if you charge for shipping (which I also recommend).

Helpful Solutions - Shipper HQ helped solve a problem we were having with shipping rates on the front end of our website. Their most basic plan was all we needed to solve our issue. Great tool to help with the shipping processes on both the front and back ends of just about any e-commerce store.

Not simple to setup - Free Support - We wanted to display an expected delivery date to our customers and this is the only app which allows you to do this. We actually wanted to use the "select a date" option but understand this is not available in the BC version due to BC coding.While Shipper HQ seems pretty easy to setup, the option we wanted simply did not work. All was setup correctly within Shipper HQ, checked and double checked.However, when testing on site, it simply states "Cannot deliver to your location" despite the location being within the setting we have entered within Shipper HQ.After leaving a negative review, we were contacted by their support team.Despite the banners everywhere stating support "starts at $500" apparently this is not true.Shipper HQ support have been instrumental in getting this issue sorted but it has taken nearly 2 weeks.Out of the box it is not, so be prepared to spend time with this despite how it seems to begin with.In the end, we got what we wanted, allbeit an expensive way of doing it.I can't give ShipperHQ 5 stars because of the setup issues and lack of clear/updated instruction in the help section.But it does what it says it will do, eventually, so if you have time to spend with this then go for it.

Expensive but very helpful. - We've been in a constant battle trying to keep our shipping pricing up to date and fair for our customers for a long, long time. ShipperHQ takes away a ton of that time and effort spent and allows us to put that time to greater use. The only downside is the monthly cost. The setup is fairly easy as well but requires a good amount of setup on the users end, however once it's set up you're ready to go for the foreseeable future.

Very Advanced, A little difficult to setup, Support available - This has allowed me to offer flat rate shipping options by zone, and to use surcharges to encourage customers to use our preferred shipping options. This is fairly complicated to setup, but they do have good support. The only real complaint I have is that their support is not "live", only by email.

Great Shipping Tool for Big Commerce - We ship with UPS and Motor Freight carriers and the connection tools to these third-party vendors for real-time freight quotes works great. We use several dimensional rules that help provide our customers with freight quotes that are an exact match. They walked us through the set-up and Quentin and their support team have been great at helping us get everything adjusted.

Potential to solve all BC's Shipping issues -

UPDATE: After spending a lot of time playing with all features (Origins, Shipping Groups, Merging Carriers, Rules etc.), I can tell you this is a fantastic app! It is capable of doing pretty much everything in terms of shipping. Their support is REAL! Absolutely amazing people! They can do so much, but BIGCOMMERCE can't. That's the issue. BC is very slow of making any improvement/adjustment. 

For example, you can't set different origin and shipping group to a product variation(option as BC calls it). If you sell a Polo Shirt in multiple colors, and those colors are stocked in different warehouses, the system will calculate shipping based on the origin of the main product.

I would love to continue to use this app, however without the ability to treat product variations differently, It doesn't justify. 

Old Review:

I've been playing with the app for a few days and so far it shows promise! I find the rules a little bit complicated to set up at first, but maybe my business doesn't require too much, and I am just overthinking. I've contacted their support and got a reply for a walk-thru the app, which will definetely be very helpful.

Customer Service has been exceptional since my first review -

Previously, I posted pertaining to ShipperHQ. I initially encountered issues with getting customer service and integration issues.  I have since spoken with them, and they have been more than wonderful in providing feedback on issues and for listening to my concerns.  Since then, they have implemented several changes that have addressed major concerns.

For example, creating a rule that charges shipping per box: create a dimensional box, then create a rule that states 'pack individually'.

Another example for creating a $5.95 per box: simply create a rule that states that a particular category is $5.95. There's no ellaborate coding required.

UPDATE

I have since deleted the app as it was not working.
