02 / Operating difference

Cross-listers copy. Sello operates.

The difference is not marketplace count. It is what happens after the fields are generated and before a failure becomes your problem.

Not copied fields. Correct marketplace data.

03 / Listing creation

From photos to complete listing.

AI creates the work. Readiness checks stop bad work from going live. You review before anything publishes.

04 / Marketplace publishing

The strongest workflow each marketplace allows.

No scraping. No botting. Your accounts stay yours. Sello says exactly what is direct, what is guided, and what is waiting on approval.

Publishes direct

Official marketplace APIs carry the listing when the account and item are eligible.

eBay

Sell API · live for selected accounts

Connect your normal eBay seller account. Payment, shipping, and returns policies must be ready.

StockX

Public API · exact catalog match

Create, activate, and deactivate after a confirmed catalog match.

Etsy

Native API, access-gated

Direct publishing and sync activate for approved connected shops.

TikTok Shop

Native API, access-gated

Shop connection, required product fields, and TikTok review may apply.

Guided publish

No official APIs exist for listing submission on these channels.

Grailed

Complete listing · final post guided

Sello formats the fields and stages photos in order. You perform the last action.

Poshmark

Complete listing · final post guided

Marketplace-specific fields are prepared, including the later mark not for sale action.

Depop

Complete listing · final post guided

The photo-first listing is assembled and checked before you post.

On approval

The product path is built, but live access has not cleared.

Vinted

Pending Vinted Pro API

Direct publishing, sync, and sold detection turn on once Vinted approves API access. Until then, the connection shows as unavailable instead of pretending.

05 / Inventory sync

After you publish is where Sello earns it.

One sale. One inventory truth.

No silent failures.

  • Linked listings keep a visible marketplace state.
  • Exceptions surface for review before they become a second order.
  • Failed delist work keeps its reason, retry, and notification history.

Pro includes assisted sold-delist. Kingpin adds full inventory sync, sold detection, and automatic delisting.

06 / Bulk operations

A rack, not an item.

Generate, price, and publish a whole batch at once. If one item fails, it is flagged for recovery and the rest keep moving.

07 / Pricing intelligence

Priced like the market already did.

Real sold comps, trimmed outliers, confidence, and separate quick-sale and list ranges. If the evidence is weak, the item says Needs comps.

09 / Operational safety

Trust is a visible state.

Every publish, connection, sale, delist, exception, and retry leaves a status the seller can inspect.

01

Readiness before publish

Required fields, account policies, catalog matches, and channel eligibility are checked before a live action.

02

Duplicate-publish protection

Idempotent operations prevent the same item action from being submitted twice.

03

Fail-closed capabilities

If a connection, permission, or adapter is not ready, Sello stops instead of pretending it worked.

04

Retry and recovery

Failed work keeps a visible state, a reason, and a path back to ready.

05

Review before live

The seller approves the listing and confirms sensitive marketplace actions.

06

Secure marketplace auth

OAuth connections keep credentials with the marketplace. No password sharing and no bots.

10 / Plans

Automation starts free. Depth scales.

Every plan includes auto-publishing. Higher tiers add volume, connections, team capacity, and deeper sold-state automation.
