Transforming Customization for America’s Largest Custom Apparel Wholesaler
Founded in 1971, SanMar quickly became a go-to source for name-brand customized apparel. For over five decades, this family-owned business has become the largest supplier of wholesale imprintable clothing and accessories in the United States, with an ever-expanding catalog that includes over three dozen brands across 3,500+ SKUs.
Precise Embroidery Estimates, Automatically Calculated
Spectrum’s platform provides real-time stitch count estimates based on artwork size and color complexity—critical information needed by decorators for accurate pricing and production planning.
What was once a required manual digitization and guesswork now happens automatically on every product detail page, streamlining the entire workflow from browsing to production-ready files.


Complete Control for B2B Accounts
SanMar’s registered accounts can submit bulk orders, select their preferred embellishment decorator, and choose fulfillment warehouses—all while viewing real-time inventory levels across SanMar’s network. This integrated workflow reduces customer service phone calls, emails, and guesswork, providing complete control and transparency from design through delivery.
And to protect their brand partners, Spectrum’s AI-powered moderation adds a layer of risk management instantly analyzing user uploaded content (including text, images and text within images), rejecting anything that may be inappropriate or offensive.
3,500+ SKUs, Infinite Customization Possibilities
Every product in SanMar’s catalog has different customization opportunities—front and back panels, sleeves, side pockets and more. Spectrum manages these placement rules across 3,500+ SKUs, showing decorators where logos can be applied and which embellishment methods are available.
The platform ensures every customization option is viable before it reaches the cart. And once an order is placed, Spectrum generates production-ready files optimized for each embellishment method—DTG, screen print, or embroidery—eliminating manual file preparation and accelerating fulfillment.
