The part that used to take all afternoon.

ChairishQueuedSelect the products, tick the channels, hit publish. Everything after that happens in the background.
Filter to everything you want listed and push the lot — no product-by-product busywork.
A single publish overtakes a bulk run, so the item you need live right now is live first.
Anything that doesn't take is retried automatically, and whatever is still wrong is written on the product in plain words.
Written the way each platform wants it.
Every marketplace has its own category tree, its own required fields and its own idea of what condition and size mean. One product record goes in, and what comes out is shaped to fit — with your own instructions layered on top.
Into their taxonomy, with the fields filled
The right category on each platform, the required item specifics answered, and the size and condition put in their words.

Your strategy, per channel
Write the rule once in plain English — cover the fees here, mention free delivery there — and every export follows it.
eBay“Add 15% to cover eBay fees, and mention free returns.”
Chairish“Add 8% for their commission. Always put the dimensions in the description.”
Storefront“No markup here. Mention free local delivery.”
A hand-built crosswalk maps your category to each marketplace's own taxonomy, and AI walks the tree for anything it doesn't cover.
eBay's item specifics are looked up for that exact category, then answered from what's on the product.
A W32 L34 becomes the size option that platform actually offers — matched by rule first, AI only when it has to be.
Where a marketplace doesn't sell that kind of thing, the item is skipped instead of rejected.
Rewritten to each platform's length limit, in the words buyers there actually search for.
Your condition mapped to the exact wording each marketplace allows — no rejected listings over vocabulary.
Say "add 15% to cover eBay fees" in plain English and the maths is applied on every export from then on.
Point one of your custom fields at a platform's attribute once, and it's used instead of a guess.
Nothing gets left off the list.
The marketplaces other crosslisting tools quietly skip are in here as well. Same one click, same sizes and categories filled in for you, same green tick when it goes live.
Poshmark, Depop, Chairish, Whatnot, Ruby Lane, Craigslist and Facebook Marketplace — listed for you like everywhere else.
No plugin, no tab left open, no laptop that has to stay awake. Start the run and close the lid.
When a channel wants a one-time code, the listing waits, you're asked once, and it picks up where it left off.
Listings go up steadily rather than all in one burst, which is how these marketplaces like it.
Sold here, gone there.
This is the part that keeps resellers up at night: the same chair sold twice, on two platforms, ten minutes apart. Stock lives in one place, so when the last one goes the other listings end themselves — and if it comes back, they go back up.

eBaywhere it soldLiveEtsyLiveShopifyLivePoshmarkLiveStorefrontLiveThe moment the last one sells, the listing comes down on every other channel it was live on.
Restock a returned item and the listings that were pulled go back up on their own.
eBay, Etsy, Shopify, Square, Wix, WooCommerce and Kashew tell us the moment an order lands; everywhere else is checked on a schedule.
Scheduled price drops push to the channels you nominate on the same run as the drop.
Price, quantity, weight and dimensions are each their own switch, per channel.
If a channel suddenly claims half your catalog has vanished, we don't believe it and nothing is delisted.
Orders come back as sales.
A marketplace order isn't a notification to act on later — it becomes a sale in ResaleOS, with the tax, the shipping, the platform's cut and the consignor's split already worked out.

Line items, tax, shipping and the platform's cut land in your books as a sale you can report on.
If the item was on consignment, the split is worked out and their balance moves the same moment.
Deducted at the location it sold from, and matched to the order so the same sale can never be counted twice.
eBay orders come back with their tracking number and what the label actually cost.
Bring the listings you already have.
You've got four hundred things live on eBay and Etsy already — nobody is re-typing those. Connect the account, run the import, and they arrive as proper products with their photos, variants and quantities attached.

Bring in what you already have listed on eBay, Etsy, Shopify, Poshmark, Mercari, Square, Depop, Chairish and more.
A matching SKU links the listing to the product you already have — even when it came from a different platform.
Every image is copied into your own library, so your catalog stops depending on their servers.
CSV import with your own column mapping for everything that never made it onto a marketplace.
The details that decide whether it actually holds up.
Crosslisting looks easy in a demo with three products. These are the parts that matter when it's three thousand.
One listing with a size matrix where the platform supports it, separate listings where it does not.
Missing photos, no price, no shipping policy — you're told before we try.
eBay's daily allowance is tracked, so big jobs wait their turn instead of erroring.
Scan a channel for listings we did not create and link them to your catalog.
Your own branded shop is another channel on the same stock, live the instant you save.
Sell it in the shop and it comes off the marketplaces like any other sale.
Push the catalog to Google Shopping and pin it to Pinterest for the traffic.
Move a product back to draft and it is unpublished everywhere it was live.
Change a title, a photo or a price and the update travels to every channel it is on.
