Seller acquisition And Merchant Onboarding Agency Seller acquisition refers to the strategic process of identifying, approaching, convincing, and enrolling new sellers or vendors onto a platform. This could be for an e-commerce marketplace, grocery delivery app, payment network, food tech app, or aggregator platform. Top agencies use a blend of field agents (feet-on-street) and digital acquisition (calls, email, WhatsApp, CRM). This hybrid model works best in cities like Mumbai, Delhi, Bangalore, and Tier 2/3 towns where personal interaction still matters.
