Most comparison pages pit one product against a competitor. That is rarely the real decision.
The real decision, for almost everyone reading this, is between changing the structure and leaving it alone. Leaving it alone is free today and expensive later. That is worth stating plainly rather than pretending the only choice is between two products.
What staying gets you
Marketplaces are genuinely good at some things. Discovery you did not pay for. A trust badge you did not have to earn. Fulfilment infrastructure that would cost real money to replicate.
If those are the reasons your store works, the honest answer is to stay. Nothing on this site improves on marketplace discovery.
What staying costs you
The costs are structural rather than itemised, which is why they are easy to miss:
- A cut taken before payout that can change without your agreement.
- A checkout you cannot alter, which means placements like an adjacent order
- bump are unavailable to you regardless of how well they would perform.
- Payout timing you do not control, including holds issued by automated flags.
- A customer list that is not yours to contact.
How to decide
Run the free audit. It gives you the leakage figure for your store rather than the industry range quoted on this site.
If the number is small, stay where you are. If it is not, you now have the number the decision actually turns on.
