Crosslist from Facebook Marketplace to Mercari — local stock, national buyers
Facebook is a radius around your postcode; Mercari is every buyer in the US, reached by post. The size limit that disqualifies half your listings, the fees, and what syncs across 50+ marketplaces.
- The move is from local to national, and that is the whole decision. Facebook Marketplace is a radius around your postcode. Mercari is every buyer in the United States, reached by post. Different audience, different economics, different items.
- Half your Facebook listings cannot come with you. Mercari’s prepaid labels stop at 50 lb, 34 inches on the longest side and 20 on the second. Sofas, fridges, wardrobes, building materials, vehicles — the Facebook Marketplace staples — simply cannot be listed.
- Mercari is ship-only now. Mercari Local, its same-day delivery service, was discontinued in November 2024, and its Meetups beta documentation is no longer published. There is no local option to fall back on.
- “Zero selling fees” is over. Mercari reversed it on 6 January 2025. The seller pays a flat 10% on the item price plus buyer-paid shipping; the buyer pays a 3.6% Buyer Protection fee. There is no separate payment processing fee any more.
- Facebook’s local sales cost nothing because Meta never touches the money. Its 10% fee, minimum $0.80, applies only to shipped orders through onsite checkout — and Meta’s own seller protection requires a Meta-issued label, which not every seller can get.
- Mercari wants data Facebook never asked you for. Category, condition, brand, size, colour, and — because they now affect your own shipping cost — weight and dimensions.
- Things Facebook allows and Mercari bans: digital goods, food and supplements, vapes, precious metals and loose gemstones, most knives, self-defence items. Mercari also forbids trades, which Facebook sellers use constantly.
- Keep your connections available on your device for listing actions. 7 days for £1, then from £9/month. There is no free plan.

Local against national: what actually changes
A Facebook Marketplace listing is an advertisement to people near you. Someone messages you, you agree a time, they turn up, you take cash. Meta is not in the transaction at all: no escrow, no fees, no order record, no rating afterwards. It is a classifieds board with a very large audience.
A Mercari listing is a nationwide shop window with a shipping obligation attached. Someone buys — no negotiation required, no meeting arranged — and you have committed to packing and posting an item to a stranger, with Mercari holding the money until it arrives.
Everything else on this page follows from that. The upside is obvious: a national buyer pool for items whose local market is thin. The specialist, the collectable, the branded thing that three people in your town want and three thousand people in the country want — that is what this route is for.
The costs are less obvious and worth naming up front. You now do packing and postage on every sale. You carry the risk of an item damaged in transit. You are graded afterwards. And you pay a fee where before you paid nothing.
The size limit that decides your catalogue
Before you think about fees or fields, run your Facebook listings against Mercari’s prepaid label limits, because this single constraint disqualifies more Facebook stock than everything else combined.
Mercari’s prepaid labels — USPS, UPS and FedEx, covering all fifty states and DC, though FedEx and UPS do not run to or from Hawaii or Alaska — cap at 50 lb actual or dimensional weight, 34 inches on the longest side and 20 inches on the second-longest.
Now think about what actually fills Facebook Marketplace. Sofas. Dining tables. Fridges and washing machines. Bed frames. Exercise equipment. Cars. Timber and paving slabs. Not one of those clears the limit, and there is no local pickup option to fall back on, because Mercari discontinued Mercari Local in November 2024 and its Meetups beta documentation is no longer published.
So sort your Facebook listings honestly:
| Travels well to Mercari | Cannot travel |
|---|---|
| Clothing, footwear, handbags | Furniture of any size |
| Small electronics, phones, tablets | White goods and large appliances |
| Games, consoles, accessories | Vehicles, trailers, parts of any bulk |
| Toys, collectibles, trading cards | Building materials, garden goods |
| Books, media, small homeware | Bulky sports and gym equipment |
| Beauty tools, jewellery (see restrictions) | Anything over 50 lb or 34 inches |
If your Facebook business is furniture clearance, this route is not for you and no tool will change that. If it is the small, brandable, searchable end of the catalogue, Mercari is where those items stop being limited to people who can drive to you.
What each takes, and who pays it
The two platforms charge in structurally different places, and comparing headline percentages will mislead you.
Facebook Marketplace has two entirely separate rails. Local pickup listings carry no Meta fee at all, for the simple reason that Meta never handles the money — you and the buyer settle it between yourselves. Shipped orders through onsite checkout are different: Meta’s own policy states it “will charge individual sellers a fee of 10% per transaction, with a minimum fee of $0.80”, and that the fee “will be calculated based on the entire amount of the transaction (including the sale prices of goods, any delivery fees and Applicable Taxes).”
Mercari ended its zero-fee experiment on 6 January 2025. Today the seller pays a flat 10% selling fee on the completed item price plus buyer-paid shipping, and the buyer pays a 3.6% Buyer Protection fee on the same base. The old $0.50 plus 2.9% payment processing charge is gone entirely.
Two consequences worth working through with your own numbers.
First, if you offer free shipping on Mercari, the 10% applies to the item price alone but the label cost comes straight out of your proceeds — which is usually worse, not better, unless the shipping is cheap enough that the conversion lift pays for it.
Second, the honest comparison for most Facebook sellers is not 10% against 10%. It is 10% against nothing, because the Facebook sales you are used to are local, cash and free. Moving an item to Mercari costs you a tenth of it. That is worth paying when the national audience is the difference between selling and not selling, and it is a poor trade on something that would have gone locally this weekend anyway.
One legacy note in case you are comparing against old advice: Mercari listings created before 6 January 2025 and never edited retain the old structure, where the buyer paid the 10%. Editing such a listing moves it onto the current terms.
Labels, protection, and Meta’s disappearing act
Mercari’s shipping story is the more settled of the two. Prepaid labels are the default, and using one buys Shipping Protection of up to $200 on standard, economy and Media Mail labels, or $20 on First-Class Envelope labels. You may “ship on your own” instead, with a valid tracking number entered in the app, but doing so forfeits Shipping Protection entirely. Dropping a parcel with the wrong carrier can void it too.
Facebook’s is messier, and if you have been selling locally you may not know any of it. Meta’s seller protection requires that “Dispatched items must use pre-paid delivery labels issued by Meta” and that “Sales must be processed through onsite checkout” — so a local cash sale is definitionally outside protection. Protection is US-only and limited to items priced at $500 or less. You must dispatch within seven calendar days or Meta may cancel the order. And a chargeback costs $20, deducted automatically, with Meta’s policy stating flatly that “Individual Sellers cannot dispute chargebacks.”
The complication is that Meta stopped issuing prepaid shipping labels for new listings in February 2025, then reinstated them around September 2025 for selected sellers only. Since Meta’s protection requires a Meta-issued label, a seller without label access effectively has no protected shipping option on Facebook at all. If that describes you, Mercari is not merely a bigger audience — it is the only one of the two where you can post something with any protection behind it.
What Mercari will not accept
Facebook Marketplace is permissive in ways Mercari is not, and several of the gaps catch sellers by surprise because the items are entirely ordinary.
Mercari prohibits weapons and most knives, self-defence items, e-cigarettes, vaping and tobacco-associated goods, all digital and downloadable items, ingestibles including food, supplements, vitamins and homemade cosmetics, gambling, raffles and mystery boxes, precious metals and loose gemstones, account credentials, human remains and fluids, and used underwear.
Two of those deserve emphasis. Precious metals and loose gemstones catches a lot of casual jewellery sellers who assume a marketplace that allows jewellery allows bullion. And digital items rules out a category Facebook groups trade in freely.
Mercari’s marketplace guidelines also ban trades and part-exchange, and require that all communication happens in the app. Off-platform meetups are prohibited. For a Facebook seller used to swapping items and moving conversations to WhatsApp, that is a real behavioural change rather than a technicality.
The data Mercari wants and Facebook never asked for
Facebook Marketplace’s listing form is thin and category-dependent: a title, a price, a category, a condition, some photographs, and a free-text description carrying everything else. Brand and size appear for some categories and not others.
Mercari expects structure: category, condition, brand, size, colour, and weight and dimensions. Coming from Facebook, expect to supply brand, size and colour properly rather than mentioning them in a sentence, because on Mercari those are how buyers filter.
This is the real work of the route, and it is worth doing once rather than badly. Where FLUF has structured data on the product — because you entered it, or because the item came in from a channel that captured it — it travels. Where the information exists only inside a Facebook description, no tool can reliably extract it, and guessing a size is worse than leaving it blank.
Why weight and dimensions are now a pricing decision
This is the newest thing on this page and the one most likely to cost you money quietly.
Mercari introduced a Best-versus-Standard rate structure: “Best rate is a lower shipping price available for packages that are 1 cubic foot or less with a longest side of 22 inches or less.” Its standard rates were updated on 20 January 2026, and its USPS Ground Advantage and Priority prepaid rates again on 7 May 2026 for a USPS fuel surcharge.
Three practical points follow.
First, packaging is now a lever. Getting a parcel under one cubic foot and 22 inches moves it onto the cheaper tariff, so how you box something affects what it costs to send.
Second, Best rate does not apply itself to existing listings — you have to edit the listing. A back catalogue migrated from Facebook and left alone will keep paying the higher rate indefinitely.
Third, wrong dimensions are not a cosmetic error. Mercari applies post-delivery adjustment charges when a parcel does not match what you declared, so an optimistic guess comes back as a deduction weeks later.
Facebook never asked you for any of this, so it will not exist in your listings. Budget the time to measure and weigh, at least for the items you list repeatedly.
Getting paid, and how long it takes
A Facebook local sale pays instantly, in cash, in your hand. Nothing about Mercari will feel that quick, and it is worth knowing the shape before the first sale rather than after it.
The buyer has three days from confirmed delivery to rate you. If they do not, Mercari auto-rates the transaction five stars — unless the buyer has reported a problem, which pauses it. Payment releases once both ratings are in.
Then withdrawal. Direct deposit is free, once per day, weekdays only, and typically takes about five business days, with a $2 non-refundable fee if a request is rejected or fails. Instant Pay costs a flat $3 per cash-out, is capped at $600 a month, requires a Visa or Mastercard debit card and ID verification, and usually lands within minutes.
So the realistic gap between selling something and having spendable money is roughly a week on the free route. If your Facebook selling is partly about turning things into cash quickly, that difference is worth planning around.
Ratings, which Facebook does not really have
Facebook Marketplace has no meaningful seller reputation. Buyers message you through Messenger, unattached to any order object, and there is no tracking, no order state and no rating that follows you.
Mercari has all of it. Ratings accumulate, negative feedback goes into a private “Things to improve” while positive feedback surfaces publicly as “Known for”, and Mercari states it “can only make positive changes to ratings”. Seller Badges are earned and can be lost — the fast-shipping badge requires dispatch within 24 hours, excluding weekends and holidays.
The adjustment for a Facebook seller is that consistency now compounds. On Facebook a slow reply or a cancelled meet costs you that sale. On Mercari it costs you a badge, and the badge was helping you sell the next thing.
Running both without selling the same thing twice
One item, two listings, two buyers is the failure this route exists to prevent — and it is worse here than usual, because a Facebook buyer is often standing in front of you.
Facebook Marketplace and Mercari require your signed-in connections to remain available on your device for listing actions.
What FLUF drives on each, stated exactly. Mercari supports mark-as-sold and order sync, so a Mercari sale can be detected and can clear the item elsewhere. Facebook Marketplace supports mark-as-sold only — it can be cleared when something sells elsewhere, but Facebook sales are not read back. Given a local Facebook sale involves no order record at Meta’s end at all, that is a limitation of the platform rather than of the integration, and the practical answer is unchanged from how you sell today: when someone hands you cash, mark it sold.
Mercari is a United States channel only. If you are selling from outside the US, this route is not available to you regardless of your Facebook activity.
What it costs
7 days for £1, then from £9/month. There is no free plan and no free tier.
Crosslisting, inventory sync, order sync and bulk operations are on every plan. Relisting, offer management and smart pricing are included from Seller (£29/month) upwards; Starter does not include them. Paying annually saves 40%.
| Plan | Monthly | Crosslisted products |
|---|---|---|
| Starter | £9/month | Unlimited |
| Seller | £29/month | Unlimited |
| Pro | £99/month | Unlimited |
| Super Seller | Custom pricing — tell us what you need | Unlimited |
Neither Mercari nor Facebook Marketplace supports relisting or offer management through FLUF, so on this particular pairing the automation tiers add nothing. Starter is the honest recommendation if these two are your only channels.

What we could not verify, and therefore left out. Any user number for either platform. Mercari publishes no US monthly active user figure — the “23 million people every month” on its corporate site is a group figure with no date, not a US one — and Meta’s widely repeated Facebook Marketplace figure traces to statements around 2021 with no current restatement we could find. So no audience number appears anywhere on this page. Whether Meta’s prepaid shipping labels are currently available to any given US seller: Meta’s US delivery articles are geo-gated and served us the UK edition, and the “selected sellers” reinstatement rests on a single secondary source. The precise field-by-field mapping between Facebook Marketplace’s listing form and Mercari’s, since Facebook’s structured fields are not publicly documented and vary by category — we describe the shape rather than asserting a mapping. Any numeric photo or description standard for either platform, because neither publishes one. And the prevalence of lowballing and no-shows on Facebook Marketplace: the structural argument is sound and sourced above, but we found no authoritative study, so no percentage appears here.

Frequently Asked Questions
No. Mercari's prepaid labels cap at 50 lb actual or dimensional weight, 34 inches on the longest side and 20 inches on the second-longest, and there is no local pickup alternative — Mercari Local was discontinued in November 2024 and its Meetups beta documentation is no longer published. Sofas, tables, white goods, bed frames, gym equipment and building materials are all outside those limits. If furniture clearance is your Facebook business, this route is not for you.
No. Mercari reversed that on 6 January 2025. The seller now pays a flat 10% selling fee calculated on the completed item price plus buyer-paid shipping, and the buyer pays a 3.6% Buyer Protection fee on the same base. The old $0.50 plus 2.9% payment processing charge is gone. Listings created before 6 January 2025 and never edited keep the old structure, but editing one moves it onto the current terms.
Only on shipped orders through onsite checkout. Local pickup listings carry no Meta fee at all, because Meta never handles the money — you and the buyer settle it directly. For shipped orders, Meta's policy states it charges individual sellers 10% per transaction with a minimum of $0.80, calculated on the entire transaction amount including delivery fees and applicable taxes. So the realistic comparison for most Facebook sellers moving to Mercari is 10% against nothing, not 10% against 10%.
Quite a lot, and some of it is unexpected. Mercari prohibits weapons and most knives, self-defence items, vapes and tobacco-associated goods, all digital and downloadable items, ingestibles including food and supplements, gambling and mystery boxes, precious metals and loose gemstones, account credentials and used underwear. The two that catch people are precious metals — sellers assume a site allowing jewellery allows bullion — and digital goods. Mercari also bans trades and part-exchange, and requires all communication to stay in the app.
Because they now decide what your shipping costs. Mercari's Best rate is a lower price for packages of one cubic foot or less with a longest side of 22 inches or less, so packaging is a genuine pricing lever. Two traps: Best rate does not apply itself to existing listings — you have to edit the listing, so a migrated back catalogue keeps paying the higher rate — and declaring the wrong dimensions brings post-delivery adjustment charges weeks later. Facebook never asked for this data, so it will not exist in your listings.
Roughly a week on the free route, which is a real change from cash in your hand at a Facebook meet. The buyer has three days from confirmed delivery to rate you, and Mercari auto-rates five stars if they do not, unless a problem was reported. Payment releases once both ratings are in. Direct deposit is then free, weekdays only, and typically takes about five business days, with a $2 fee if the request fails. Instant Pay costs a flat $3, is capped at $600 a month and needs a debit card and ID verification.
Keep your Facebook Marketplace and Mercari connections signed in and available on your device for listing actions. Follow the supported setup prompts in FLUF Connect.
Yes, once you mark it sold. Facebook Marketplace supports mark-as-sold, so clearing it there clears it on Mercari and everywhere else you have connected. What does not happen is automatic detection of a Facebook sale — a local cash sale creates no order record at Meta's end for anything to read, so the platform gives nothing to detect. Mercari is better served: it supports order sync as well as mark-as-sold, so a Mercari sale can be picked up and can clear the item elsewhere.
Not for this route. The Mercari channel FLUF drives is the US site, and it is a United States channel only. Mercari Japan is a separate marketplace, and Mercari's UK operation closed years ago. If you are selling from outside the US, Mercari is not available to you whatever your Facebook Marketplace activity — but 50+ other marketplaces are, and several of them are strong in exactly the categories Mercari serves.
