Ecommerce inventory management

One source of truth — ecommerce inventory management

Selling across Shopify, eBay, and Amazon multiplies the ways inventory goes wrong. Kesper keeps stock synced across channels, catches ghost stock the day it starts hiding, and reorders to real demand — for $49/month flat.

Why multichannel inventory drifts out of sync

  • —The same unit listed on three channels can sell twice — and the oversell fees, cancellations, and rating hits all land on you.
  • —Ghost stock from migrations and miscounts blocks reorders and fakes your availability until a customer order surfaces it.
  • —Slow and expiring SKUs tie up cash while you're busy shipping — and nobody has time to audit the whole catalog.
  • —Reordering by gut overstocks your worst sellers and runs out of your best.

How Kesper manages ecommerce inventory

NEXUS

Cross-channel stock sync

Keeps physical, online, and marketplace inventory reconciled so a unit sold on eBay isn't still for sale on Shopify or Amazon — cutting oversell fees and cancellations.

SHERLOCK

Nightly ghost-stock detection

Zero-sales-in-stock, expiry projections, and velocity drops caught every night and handed to you as a short spot-check list.

PROPHET

Reorder to real demand

Projects demand per SKU from your actual sales so you reorder to velocity — not a guess that stocks out your best sellers.

MONICA

A daily brief, not a dashboard

The inventory actions that matter land in a 7 AM Slack brief, ranked — every finding cited, missing data named honestly.

Questions

Which channels does it support?

Shopify, WooCommerce, eBay, Amazon, Poshmark, and Mercari, plus a developer API for anything else. It reads your data and stays read-only until you approve an action.

Is it a new inventory system to migrate to?

No — Kesper is an intelligence layer on top of the stores and marketplaces you already sell on. Nothing to migrate; connect in about 60 seconds.

How does it catch ghost stock?

SHERLOCK runs nightly passes for zero-sales-in-stock and velocity anomalies and surfaces a spot-check list each morning — so distortions get caught the day they start, not at the next full count.

What does it cost?

$49/month flat for every channel and store on the account. 7-day free trial, no card, cancel anytime.
