Rush Order Tees: Scaling custom apparel fulfillment without slowing down<\/h2>\n\n\n\n

For over two decades, Rush Order Tees<\/a> has been printing custom apparel for customers nationwide\u2014t-shirts, hoodies, hats, and specialty items, spanning a catalog of over 3,000 products. Today, the company fulfills millions of orders annually, shipping thousands of packages every single day.<\/p>\n\n\n\n

That kind of volume demands more than good intentions\u2014it takes a shipping operation that can match the pace of a production floor running full tilt.<\/p>\n\n\n\n

“Our goal is to maintain industry-leading turnaround times and accuracy,” said CEO Mike Nemeroff. “Our shipping needs focus on reliability, automation, lower error rates, and intelligent label generation across multiple carriers.”<\/p>\n\n\n\n

For years, ShipStation API<\/a> has been at the core of how Rush Order Tees makes that happen.<\/p>\n\n\n\n

When growth outpaces your processes<\/h2>\n\n\n\n

Before ShipStation API, shipping at Rush Order Tees was a patchwork\u2014manual label creation here, partial automations there, and disconnected carrier tools everywhere. It worked until the orders started stacking up faster than the team could print labels.<\/p>\n\n\n\n

“All of that created inconsistencies, more errors, and slower daily throughput,” Nemeroff explained.<\/p>\n\n\n\n

The turning point was simple: growth. Order volume kept climbing, but the semi-manual processes couldn’t keep pace. Speed suffered. Errors crept in. And adding headcount wasn’t a sustainable solution.<\/p>\n\n\n\n

“We needed a scalable API-driven system that could grow with us,” Nemeroff said.<\/p>\n\n\n\n

Building a shipping engine for scale<\/h2>\n\n\n\n

Rush Order Tees needed an API that could handle batch processing and multi-carrier rate shopping<\/a> for thousands of daily shipments without flinching. Real-time syncing. Automation rules that didn’t require babysitting. And crucially, support for massive daily volume without the system grinding to a halt.<\/p>\n\n\n\n

ShipStation API checked every box.<\/p>\n\n\n\n

“ShipStation API centralized and automated our entire shipping workflow\u2014batch label creation, carrier rate optimization, status syncing, and error-reduction checks. It enabled consistent, high-volume throughput while reducing labor cost per shipment.”<\/p>Mike Nemeroff, CEO<\/cite><\/blockquote><\/figure>\n\n\n\n

Connecting the dots across production<\/h3>\n\n\n\n

Rush Order Tees doesn’t operate like a typical ecommerce business. Custom apparel production involves internal routing systems, order staging, and coordinated workflows across facilities. Any shipping solution would need to integrate directly with those existing systems.<\/p>\n\n\n\n

“We connected our internal production-routing and order-staging systems directly to ShipStation API to automate label creation, shipping notifications, and inventory movement according to our production workflow,” Nemeroff explained.<\/p>\n\n\n\n

The integration was smooth. Rush Order Tees completed the core implementation within a few weeks, with incremental improvements added afterward as needs expanded.<\/p>\n\n\n\n

Keeping customers in the loop with Klaviyo<\/h3>\n\n\n\n

Shipping custom apparel means customers are often eagerly tracking their order\u2014they’ve got an event, a team, a deadline. Rush Order Tees paired Klaviyo<\/a>, an email and SMS marketing platform, with ShipStation’s API to ensure customers never have to wonder where their packages are.<\/p>\n\n\n\n

“It automatically triggers precise, real-time shipping and delivery notifications,” Nemeroff said. “That improves customer experience and increases post-purchase engagement.”<\/p>\n\n\n\n

Because ShipStation’s API feeds shipment data directly into Klaviyo, Rush Order Tees can customize those touchpoints\u2014branded emails, SMS alerts, delivery confirmations\u2014without building any of it from scratch.<\/p>\n\n\n\n

The results speak in hours saved and errors avoided<\/h2>\n\n\n\n

The impact of ShipStation API wasn’t incremental\u2014it was transformational.<\/p>\n\n\n\n

“Automation eliminated thousands of manual actions per day, freeing our team to focus on production and quality rather than repetitive shipping tasks.”<\/p>Mike Nemeroff, CEO<\/cite><\/blockquote><\/figure>\n\n\n\n
