Should I sell on marketplaces or my own store?

Both. Marketplaces like eBay and Amazon bring reach but charge commissions and own the customer. Your own total.supply store keeps margins, data and the relationship. total.supply lets you do both from one catalog.

Does total.supply replace eBay and Amazon?

No — it complements them. You run your own branded store and sync the same catalog to eBay and Amazon, so you get reach and ownership.

Your own store and the marketplaces.

Marketplaces bring reach; your own store keeps margins, data and the customer relationship. With total.supply you don't pick one — you run both from a single catalog.

Marketplace-only vs. your own store.

Consideration	Your total.supply store	Marketplace only
Commission per sale	None — keep 100%	Typically 8–15%+
Customer relationship & data	Yours	Owned by the marketplace
Your brand & domain	Yes	Marketplace branding
B2B quotes & RFQ	Built in	Rarely supported
Built-in buyer reach	Bring your own + channels	Large existing audience
Sell on both at once	Yes — sync to eBay & Amazon	Single channel

General guidance; marketplace fees vary by category and program. eBay and Amazon are trademarks of their respective owners; total.supply is not affiliated.

The smart play

Use marketplaces for reach, your store for margin.

The mistake is treating it as either/or. Win new buyers on eBay and Amazon, then bring repeat and high-value buyers to your own store where you keep the margin and the relationship — all from one synced catalog.

List once and sync inventory so you never oversell.
Keep 100% of revenue on direct sales — no commission.
Own buyer data and build repeat business off-marketplace.

Buyer checklist

How to evaluate this alternative in real B2B terms.

Comparison pages are most useful when they map to daily selling work: product data quality, negotiated pricing, buyer requests, gateway choice, marketplace reach and support burden. Use this checklist before choosing a platform or migrating an existing catalog.
