StickerCactus — B2B Custom Sticker Store with TeeinBlue & SparkLayer

StickerCactus is a wholesale-only B2B storefront for custom stickers. UpSolite configured TeeinBlue for premium product customisation, built custom logic to bridge customisation data into SparkLayer's B2B cart, created a wholesale account impersonation dashboard for account management, and implemented Locksmith API logic for B2B menu and product access control — making two disconnected systems work as one seamless flow.
