The problem

Bulk listing on eBay has always meant CSV templates and spreadsheet hell.

Sellers who try to scale on eBay run into a familiar wall: the form-based listing flow doesn't scale, so they reach for "bulk" tools — which turn out to be CSV import templates with 60+ columns. The bulk workflow becomes: build a spreadsheet, validate the columns, fight the format errors, re-upload, fix the failures, and finally see the listings go live. For most sellers, the CSV is slower than just listing one at a time in Seller Hub.

Modern bulk listing should mean: drop a pile of photos, get a pile of listings. No CSV, no template, no column mapping. The AI handles the cataloging; you handle the approval. Pile Mode™ is exactly that — an upload bin that accepts 10 to 500 photos in a single batch, parallel-processes them through the AI, and produces a review queue of complete listings ready to ship to eBay.

This isn't a faster spreadsheet. It's a different workflow entirely. The thing that took an afternoon now takes a coffee break.

What you get

Capabilities built for this exact workflow.

  • Pile Mode™: 10–500 items in one upload

    Pile Mode is the bulk-intake interface. Drop up to 500 photos in a single batch, mix categories freely, mix multi-photo items with singles, mix branded and unbranded inventory. The AI runs identification in parallel across the queue, typically returning a ready-to-review batch in under two minutes for 100 items.

  • Auto-grouping for multi-photo items

    When an item is photographed from multiple angles, HumCity groups the photos into a single listing automatically. Visual similarity and metadata (timestamp, location) drive the grouping. You can override in the review queue — split a multi-item shot into separate listings, or merge separately-shot photos into one.

  • Duplicate detection across the queue

    Photograph the same SKU twice and HumCity flags the duplicate before publish. For sellers running inventory with multiples (sealed wax, multi-quantity apparel), duplicates are consolidated into multi-quantity listings automatically. For one-of-a-kind items where the duplicate is a true mistake, you decide whether to delete or keep both.

  • Bulk publish to eBay with one approval

    Approve the queue and publish all listings to eBay in one batch via the official API. Bulk publish supports scheduled launches — queue 200 listings to go live together at 7 PM Eastern (peak buyer hours), or stagger launches over a multi-day window.

  • Keyboard-first review queue

    Most of the time-savings come from a review interface designed for speed. Arrow keys to navigate, J/K to approve/edit, Cmd+Enter to publish, U to uncrop, R to retry the AI. A skilled reviewer can clear a 100-item queue in 10–15 minutes — about 9 seconds per listing.

  • Bulk-edit across any selection

    Select an arbitrary subset of the queue and edit a field across all of them at once. Change the shipping policy on 50 listings. Drop prices 10% on a slow-moving category. Apply a SKU prefix. Add a return policy clause. Bulk-edit handles every editable field in the listing.

Use cases

Built for the way real resellers work.

Whole-store intake sessions

Sellers who batch their listing work into dedicated sessions (e.g. one big intake day per week) get the most leverage from Pile Mode. Photograph the whole intake, drop it as one upload, and the AI processes the entire week's inventory before you've finished your second cup of coffee.

Estate and liquidation buys

Buying a 500-piece estate is a sourcing win and a cataloging nightmare. Pile Mode ingests the estate in batches and produces a complete catalog ready to triage. Items can live as drafts until you decide which to list, which to wholesale, and which to send to grading without ever opening a spreadsheet.

Card breakers running pile sessions

Breakers ingest hundreds of cards per session and need them listed before the next break. Pile Mode handles the volume — a 300-card pile becomes 300 listings in under 10 minutes including review time. Slabs and raw cards both supported in the same batch.

Closet-clearout and personal-collection sellers

Clearing out a closet or a personal collection is typically blocked on the listing work, not the photography. Pile Mode reduces the listing work to a single afternoon — photograph everything, drop it, review the queue, publish. The result is the same as if you'd hired a lister, at a fraction of the time cost.

How it works

From inventory to live listings in three steps.

01

Drop the pile

Mixed inventory? No problem. HumCity groups items automatically and runs every category in parallel.

AI builds every listing

Titles, item specifics, category, condition, and pricing generated in parallel across the batch.

03

Bulk approve

Scan the queue with keyboard shortcuts, approve in batches, publish to eBay.

FAQ

Common questions

How big can a batch be?
Pile Mode supports up to 500 images per batch on every paid plan. Most sellers run batches of 30–100 items in a single pass — a sourcing haul or a day's intake. Larger batches are supported; the AI inference time scales sub-linearly because items are processed in parallel.
Does it dedupe duplicates?
Yes — HumCity flags visually similar items in the queue and lets you merge, split, or delete duplicates before publish. For sellers running multi-quantity inventory (sealed wax, apparel), duplicates can be auto-consolidated into multi-quantity listings.
Can I bulk-edit listings after generation?
Yes. Bulk-edit handles every field in the listing — title, price, shipping, return policy, item specifics, condition, SKU. Select an arbitrary subset of the queue and apply changes across all of it in one keystroke.
Does Pile Mode work for mixed-category inventory?
Yes — Pile Mode is category-agnostic. A single batch can include cards, apparel, electronics, home goods, books, and collectibles. The AI routes each item to the right eBay category individually.
Can I schedule listings to go live at specific times?
Yes. Scheduled launches let you queue a batch to publish at a specific time — for example, all listings launching together at 7 PM Eastern. You can also stagger launches over a multi-day window for steady inventory drip.
What happens if a listing fails to publish?
Failures are surfaced in the queue with the eBay error message and a one-keystroke retry. The rest of the batch publishes normally — a single failure doesn't block the rest of the queue.
Can I save bulk-edit templates for repeat use?
Yes. Common bulk-edit patterns (shipping policy override, return policy clause, SKU prefix application) can be saved as templates and applied to future batches in one keystroke.
Do scheduled launches respect my eBay listing-creation rate limit?
Yes. Pile Mode publish respects eBay's API rate limits and queues publishing requests behind the scenes. From your perspective, you click approve once; the system handles the rate-limiting.
Can I export the queue as a CSV for backup?
Yes. The full queue can be exported as CSV at any point — useful for backup, external review, or one-time import to another system.
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.
