Marketplace P&L to Owned Ecommerce Channel

Situation

This is not consulting theory. It is a P&L I operate. A battery retail operation (lithium house and marine batteries, $25 to $9,999 CAD price points) selling through eBay, with the long-term goal of moving revenue to an owned channel A sales channel you control end to end, your store, your list, your margins, instead of renting demand from a marketplace that sets the rules. .

Problem

Marketplace rent is brutal and invisible until you quantify it: on $38.6K of item sales, eBay selling costs ran $11,905, roughly 31%. Shopify was evaluated and abandoned over its fee stack. Every dollar of growth on a rented channel grows the landlord’s take. The business needed an owned storefront engineered for high-ticket trust: nobody impulse-buys a $2,000 battery bank.

Approach

Run the marketplace channel profitably first, it funds everything and proves demand, while building the owned channel deliberately. The eBay store was operated to 313 lifetime sales at 100% positive feedback. In parallel I built LFPO4.com on WooCommerce: 85 products, live Stripe processing, and buy-now-pay-later (Affirm, Klarna, Afterpay) because financing is how high-ticket consumer hardware actually sells.

Architecture and key decisions

• WooCommerce over Shopify, decided on fee math. For this catalog and order profile, platform rent and payment lock-in made Shopify structurally worse; self-hosted WooCommerce trades convenience for margin, the right trade at this AOV.
• A bundle engine with a real admin UI. Kit-building (battery + charger + monitor) targets a $1,099 AOV, and the owner can compose bundles without a developer. Every feature ships with its admin surface.
• BNPL as conversion infrastructure, not a checkbox. Three providers wired in, because approval rates differ and a declined financing offer is a lost $1,500 order.
• Trust engineering for high-ticket. Spec tables, warranty clarity, and the public eBay feedback record doing double duty as social proof.

What shipped

A live, operating eBay channel; a live WooCommerce storefront with 85 products, bundles, BNPL, and Stripe; and the operational scaffolding around both: fulfillment workflow, support, content pipeline, and channel-level P&L tracking.

Outcome

$43,643 gross and $29,138 net across January–May 2026 on the marketplace channel, with roughly C$101K of GMV represented on active listings. The owned channel is live; the fee-savings delta per order as volume shifts from eBay to WooCommerce is the next number being measured.

What this demonstrates

I have run the register, not just advised from beside it. Pricing, fees, fulfillment, support, conversion, financing, the full operating loop of an ecommerce business, with a publicly verifiable track record. When I tell a distributor or DTC operator what will move their channel economics, it comes from operating one.
