Marketplace Dependency Is a Business Risk, Not a Marketing Problem

A seller can have good sales and still be exposed. Platform fees, campaign rules, account policies, limited customer access, and algorithm visibility can all change. Shopee's fee documentation already shows how costs vary by seller type, category, and program S1S2.

Indonesia's online demand is still growing, with ecommerce GMV at $71B in 2025 S3. That makes marketplaces important. It also makes dependency more dangerous, because more of the business sits inside someone else's rules.

Retention research explains why. Existing customers are often much cheaper to keep than new ones are to acquire S4. If the only path back to them is a platform feed, paid ads, or marketplace notifications, the business has weak fallback.

CRM research points to a better structure: multichannel integration, information management, and performance assessment S5. That is what an owned sales channel gives you.

• Platform risk: fees, search visibility, campaign dependency, customer access, account policy.
• Operational risk: buried chats, no owner, no follow-up SLA.
• Revenue risk: repeat orders must be won again instead of reactivated.

Corkcicle's 93% growth in flow revenue after consolidating email and SMS fits this article because the gain came from owned lifecycle messaging [S10]. Good Protein's 30x Klaviyo ROI points in the same direction [S9].

The practical takeaway: do not celebrate channel dependency. Build the layer that still works when one channel gets expensive or noisy.
