TikTok Included Beside Amazon and Walmart in RFPs
TikTok Shop is moving from a peripheral mention to a named, budgeted channel in formal agency RFPs, appearing alongside Amazon and Walmart. Agencies and measurement firms report growing enterprise interest: Podean says brand inquiries are up significantly year-over-year and contracts are typically 12 months or longer. Sales from brands with $30M+ annual revenue rose 97% year-over-year on TikTok Shop, with transaction volume up nearly 80%. Brands including Ulta Beauty, Sally Beauty and PepsiCo have launched storefronts or invested in the format. Measurement providers like Prescient AI are adding TikTok Shop connectors every two to three days. Agencies note TikTok Shop often looks loss-leading on direct attribution, but drives measurable halo lifts on other retail channels when used as an upper-funnel, creator-driven tactic (notably via TikTok’s GMV Max). Ownership of Shop capabilities remains fragmented between social and marketplace teams, and many winning shops are run in-house.
