Marketplace Expansion & Management

Yes, and most scaling brands sell on Shopify and Amazon simultaneously. The failure mode is running them as isolated silos, treating Amazon as a pure revenue channel and Shopify as your “real” brand. The better frame: Shopify is your owned audience and first-party data; Amazon is your acquisition engine and discovery surface. Most mid-size brands land at 50–70% Amazon revenue and 30–50% Shopify, with the Shopify share growing as the brand builds direct traffic. Duplicate listings, pricing mismatches, and conflicting promos are the three most common mistakes.

To get approved on Walmart Marketplace, you need a US business entity, US tax ID, US-issued business address, US-based inventory or fulfillment, and a track record on another eCommerce platform like Amazon, Shopify, or BigCommerce. Walmart prefers brands with established eCommerce history. Pure first-time sellers face more scrutiny. The application takes 2–4 weeks and includes verification of UPCs, product imagery, and a category-fit review. Approval rates jumped after Walmart opened the marketplace more aggressively in 2023; today most legitimate brands with existing channels get approved within a month.

To get approved on TikTok Shop, you need a US entity, US business documentation, eCommerce history on another platform (Amazon, Shopify), and category fit. Applications take 5–10 business days through TikTok Seller Center. TikTok Shop initially restricted certain categories (firearms, supplements with health claims, alcohol); the eligible category list has expanded since 2023. First-time eCommerce brands face more friction; established brands with social presence get fast-tracked. Approval is denied most often for incomplete tax documentation or for products in restricted categories.

Target Plus is invite-only. There is no application form. Invitations come through Target’s category buyer team, typically targeting brands with proven eCommerce momentum, retail-quality packaging, and strategic fit with Target’s existing assortment. Paths to an invitation: introductions through retailer brokers (Crossmark, Acosta), exhibiting at category trade shows where Target buyers attend, achieving meaningful Amazon/DTC traction that puts you on category buyer radar, or partnering with an agency that has existing Target Plus relationships. Cold outreach to Target.com directly rarely works; relationship-driven introductions almost always do.

Pick your post-Amazon marketplace by category: Walmart for commodity CPG (food, household, supplements), Target Plus for premium DTC-style brands that can secure an invite, and TikTok Shop for visual or impulse categories (beauty, fashion, home decor, kids products). Commodity CPG → Walmart first; Walmart’s everyday-low-price shopper matches the category best. Premium DTC-style brands → Target Plus first (when you can get in); Target’s curated marketplace fits brand-driven categories. Visual/impulse categories → TikTok Shop first; the platform’s discovery mechanic fits scroll-driven categories. Brands trying to do all three at once usually under-resource and underperform on each.

Yes. One agency can manage Amazon, Walmart, TikTok Shop, and Instacart together, but expertise depth varies dramatically by marketplace. Most agencies that claim multi-marketplace coverage are deep on Amazon and shallow on the others. The right diligence: ask the agency to walk you through a specific Walmart Connect campaign decision, a TikTok Shop creator program, and an Instacart attribution challenge. Surface-level competence doesn’t survive that conversation. Specialists per marketplace deliver better results below $10M total marketplace revenue; integrated multi-marketplace agencies start to make sense above $20M.
