Customer Testimonials

Giordano's needed to update its ecommerce stack, specifically with a migration from a legacy ecommerce platform to Shopify. We have a complex business: multiple ecommerce channels (Shopify and third-party sites), a mix of in-house and 3PL fulfillment, and unique shipping rules since we ship a frozen product. This was a daunting project at the start, but String truly provided a customized solution that met every requirement. I was continually impressed by what I thought would be a difficult ask was no big deal for the String team to implement, which not only helped us launch, but gives me confidence that String will be a long-term strategic vendor partner as we scale our business.

Director Ecommerce, Giordano's

We used to spend a significant amount of time manually creating ShipStation batches, grouping orders by product, and selecting carriers. All of that slowed our team down and introduced unnecessary complexity. String came in and built custom automation and logic that now reviews shipping rates and automatically chooses the most cost-effective carrier while still meeting our delivery expectations. They also implemented auto-batching, so each morning our orders are already organized by product and ship date, which makes printing and processing incredibly streamlined. Their support has been fast, thoughtful, and awesome to partner with. We're truly grateful for the impact they've made.

String has had a substantial impact on our fulfillment process. It has led to substantial cost savings on shipping, reduced time spent on ticket preparation for fulfillment and a decrease in customer complaints due to the unshipped order reporting feature. We are extremely satisfied with all aspects of String's service.

String is super set-in-and-forget-it in nature. We don't ever really have to worry about it working - it just works, and actively saves us money on a daily basis. What's particularly cool is that it's dynamic. As rate cards shift, the algorithm immediately adapts.

String has not only allowed us to take full advantage of our current parcel rate structures but has also helped us improve them. We have parcel carriers now fighting for our business while we are enjoying lowered order processing times!

String is like hiring a cool robot that figures out the best package and cheapest shipping service for each order - it's especially handy when you're dealing with new shipping services or rate changes and does a great job of making our team more efficient AND more accurate.
