Spark advertised the app could integrate with our supplier and included a predefined integration option which was meant to be straightforward. After 9 weeks of going back and forward with Spark it became evident that they provided completely missleading information about integrating with our supplier and made excuse after excuse as to why it couldnt work. They placed blame on our supplier, when in fact it was their software that was never configured to work - they were even using older API v5 calls, instead of v6 - they eventualy upgraded their connectivity to v6 to then find other aspects of their software integration was not compataible. I eventually decided to outsource the API integration to a company in Europe and they had everything up and running in 2 weeks built from the ground up, and the cost was equivelent to 6 months of their $249 per month fee!!!! Support couldnt care less if you were uip and running or not, they only started to slightly help more once I asked for a refund.

Spark Shipping works very well. Their customer support is some of the best of any vendor I've ever worked with. Working with the app and the support team makes my life easer and that's pretty rare in the 3rd party vendor space.

​I use spark shipping for not only my bigcommerce store but for my Shopify stores also. They are awesome and amazing. Their customer support team is the best. They have not only managed to accommodate and make every request i have had of them happen but they made it happen quickly. I had some unique needs for my fulfillment files and they worked with me to make them happen. They went above and beyond in my opinion. I could not be more pleased with my experience with Spark Shipping. If you are looking for a company to handle any of your needs for a bigcommerce or shopify store do not hesitate to go with Spark shipping.

Charles has been super helpful through the entire set up process. We've been working with them for several months. Keep up the great support!
