The short version
- Only Mercari has a free tier, so it costs nothing to try first.
- Each has a real cost: Mercari the flat 10 percent commission plus payment processing fees applies even to very low-value items, so selling something for a few dollars can leave the seller with proportionally little after fees and packaging.; Slice the platform sells only to pizzerias, so a group that adds a second concept has to run a separate ordering stack for it.
- They diverge on capability: Mercari covers Flat seller commission, Slice covers Flat fee per order.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Mercari
- The flat 10 percent commission plus payment processing fees applies even to very low-value items, so selling something for a few dollars can leave the seller with proportionally little after fees and packaging.
- Shipping is the seller's responsibility to arrange and package correctly, and disputes over item condition or damage in transit are common friction points in buyer-seller resolution.
- Instant payout carries its own fee on top of the selling and processing fees already deducted, so getting money out quickly costs more than waiting for standard transfer.
- Buyer protection and authenticity verification are limited outside the specific luxury authentication programme, so counterfeit risk on unverified categories rests largely on buyer judgement of listing photos and seller ratings.
- Market depth and typical sale prices vary significantly between the Japan and US versions of the app, and the two operate as largely separate marketplaces despite the shared brand.
Slice
- The platform sells only to pizzerias, so a group that adds a second concept has to run a separate ordering stack for it.
- The consumer marketplace lists nearby competitors alongside you, and the flat order fee is charged even on repeat customers you introduced yourself, so you pay indefinitely for demand you already own.
- Slice Register is a much younger product than general purpose restaurant POS software and its reporting, inventory and multi location features are thinner than what an established POS offers.
- Delivery fulfilled through third party fleets is billed per delivery on top of the order fee, so the true cost per delivered order is well above the headline flat fee.
- Group purchasing savings depend on switching or supplementing your existing distributor and meeting order minimums, which small shops with limited storage often cannot do.

Answered from the vendors’ own pages
Mercari: How much does Mercari charge sellers?
A flat 10 percent selling fee on the final sale price in the US, plus a separate payment processing fee, both deducted from the seller payout.
Slice: Does Slice take a commission on orders?
No. It charges a flat amount per order, so the fee does not rise with ticket size. Delivery, if you use the Slice driver network, is billed separately per delivery.
Mercari: Does the buyer pay any extra platform fee?
No separate platform fee is added at buyer checkout the way Vinted adds a buyer protection fee; the buyer pays the listed price plus shipping if not included.
Slice: Do I have to use Slice Register to get online ordering?
No. Ordering works alongside most common POS systems, and many shops take Slice orders on a tablet without any POS integration at all.
Mercari: Is Mercari the same marketplace in Japan and the US?
No, they operate as separate marketplaces under the same brand, with different inventory, pricing and fee history.
Slice: Will customers know they are ordering from my pizzeria or from Slice?
Both happen. Orders placed on your branded site look like yours; orders placed in the Slice app come from a marketplace where your listing sits beside other pizzerias.
Slice: Is it available outside the United States?
No. Slice operates in the United States only.
