The problem

Most reseller inventory never gets listed — because the listing work outpaces the sourcing.

Talk to any high-volume reseller and you'll hear the same complaint: the back room is full of inventory that hasn't made it to eBay yet. The sourcing pace is fast (estate sales, clearance runs, wholesale lots) but the listing pace is slow (10 minutes per listing in Seller Hub). The gap compounds. Within months, the unlisted inventory pile is bigger than the active listings.

The standard responses are: hire listers (expensive, hard to manage), use a VA (variable quality, communication overhead), or accept a permanent backlog (revenue left on the table). All three responses treat the listing work as a labor problem rather than a tool problem.

HumCity treats it as a tool problem. The inventory-to-listing pipeline becomes: photograph as you receive, AI generates the listing in the background, bulk approve from a keyboard-first queue, publish on your schedule. The pipeline scales with sourcing instead of capping below it.

What you get

Capabilities built for this exact workflow.

  • Photo-first inventory ingestion

    The inventory record starts with the photo. Snap as you receive — at the unload bay, at the workbench, at the lightbox — and the photos become inventory items in HumCity automatically. The AI generates the listing data in the background; you don't have to make the listing decision at intake time.

  • Auto-grouping for multi-photo items

    Multi-angle photos of the same item are grouped into a single inventory entry automatically. This matters because most items get 3–5 photos and you don't want 3–5 inventory entries per item. Visual similarity and timestamp drive the grouping; you can override in the inventory view.

  • AI-generated listings with full item specifics

    Every inventory item ships with a complete draft listing — title, category, item specifics, condition, description, suggested price. You can publish immediately, hold as a draft, schedule for later, or hold for a different channel. The inventory record persists even if you decide not to list.

  • Bulk publish and scheduled launches

    Approve a selection from inventory and bulk-publish to eBay via the official API. Scheduled launches let you queue a batch to go live at a specific time — useful for staging weekly drops or coordinating launches around marketing campaigns.

  • Inventory tagging, folders, and search

    Tag inventory items by source (estate, retail arb, wholesale), by category, by condition band, by intended channel. Folders let you organize by sourcing trip or by season. Full-text search runs against titles, item specifics, and tags so you can find anything in a 10,000-item inventory in seconds.

  • Multi-store and multi-channel support

    Connect multiple eBay stores on Pro and Scale plans and route inventory between them. Items can also be held as drafts for channels that aren't live yet (Mercari, Whatnot, Shopify) so the inventory record carries forward when those channels ship.

Use cases

Built for the way real resellers work.

Resellers with a backlog problem

If you have a back room full of unlisted inventory, the inventory-to-listings pipeline is the most valuable tool to adopt. HumCity ingests historical inventory the same way it ingests new — photograph the pile, drop it, and the AI catches up. The backlog clears in days instead of months.

Wholesale and liquidation buyers

Wholesale lots and liquidation pallets arrive as mixed inventory that needs cataloging before any decisions can be made. HumCity ingests the lot, produces a valued catalog, and lets you triage what to list, what to wholesale, and what to scrap. The cataloging step shortens from days to hours.

Multi-channel sellers staging inventory

Sellers running multiple channels (eBay + Whatnot, eBay + Shopify) often want inventory to live in one place and route to the right channel based on category or velocity. HumCity is the inventory hub — items carry tags and metadata that drive routing decisions, and the same inventory pushes to whichever channels you connect.

Seasonal and event-driven sellers

Some sellers operate around event drops (sports card releases, sneaker drops, comic launches) and need inventory staged in advance to launch the moment the event hits. Scheduled launches let you have 200 listings ready to go live at a specific moment — for example, all rookie-card listings launching the morning after a player's first MVP win.

How it works

From inventory to live listings in three steps.

01

Capture inventory

Photograph as you receive. HumCity ingests in the background while you're still unloading the truck.

02

AI builds listings

Every item turns into a draft listing with all required eBay fields. Holds as inventory until you decide to publish.

03

Publish on your schedule

Bulk approve, schedule launches, or push live immediately. Inventory tags carry through to the published listing.

FAQ

Common questions

Can I keep inventory unlisted in HumCity?
Yes — items live as drafts until you publish. You can tag, sort, search, and bulk-edit the inventory indefinitely without ever pushing to eBay. This is useful for inventory staging, seasonal holds, and triaging large estate buys.
Does it support multiple eBay stores?
Yes — connect multiple eBay accounts on Pro and Scale plans. Inventory items can be routed between stores or duplicated across them. Each store keeps its own published-listings view, but the inventory catalog is unified.
Can I add custom fields to inventory items?
Yes. Custom tags and folders cover most organization needs. Custom structured fields (cost basis, source supplier, location code) can be added per item and used in bulk-edit and reporting.
How big can the inventory get?
There's no hard limit. Pro and Scale customers commonly carry 10,000–100,000 inventory items. Search and filter performance is designed for the high end of that range — typical query response is sub-second.
Can I import existing inventory from another system?
Yes. Import supports CSV from most listing tools, plus direct import of active eBay listings on store connection. After import, you can re-run AI enrichment on existing items to fill in item specifics that the previous system didn't capture.
Does the system track inventory cost basis and profit?
Yes. Cost basis can be set per item or per batch, and the dashboard surfaces sell-through and profit-margin reporting. Integration with QuickBooks and other accounting tools is on the roadmap.
Can I schedule listings to launch in stages?
Yes. Scheduled launches support both batch launches (all listings going live together) and staggered launches (drip-feed over a multi-day window). Useful for steady inventory velocity or for coordinating with marketing campaigns.
What happens to inventory when an item sells?
Sold items are marked sold in the inventory catalog automatically when the eBay sale syncs back. Multi-quantity items have the quantity decremented. Cost basis and profit are calculated against the sold-price.
Does it integrate with shipping software (Pirate Ship, ShipStation)?
Direct shipping integration is on the roadmap. Today, sold listings flow back to eBay's normal order pipeline and you fulfill through your existing shipping workflow.
Is there a free tier?
Yes. Every account gets 50 free listings or revisions per month with no credit card required. Most resellers can fully evaluate the AI workflow, image recognition, and bulk upload before deciding to upgrade. Paid plans start at $10/month for 500 listings and scale with volume.
Does HumCity use the official eBay API?
Yes. HumCity is an authorized eBay API partner and uses the official Trading and Inventory APIs. Every listing published from HumCity appears in eBay Seller Hub normally, counts toward your eBay reputation, and respects your existing business policies for shipping, returns, and payments.
