D2C brand: overselling eliminated across five sales channels

Selling on its own website plus four marketplaces, the brand was overselling roughly 4% of orders and eating cancellation penalties and rating damage. We built a single inventory truth with near-real-time propagation to every channel, plus automated settlement reconciliation.

The situation

What was broken

  • Inventory maintained separately per channel and updated manually twice a day
  • ~4% of orders oversold, triggering marketplace penalties and rating damage
  • Marketplace settlements reconciled quarterly, if at all — real margin per channel was unknown
  • Returns processed manually with no link back to stock

The work

What was actually done

  1. 01

    One inventory source of truth

    ERP designated as the system of record, with reserved-stock logic and per-channel buffers so fast-moving SKUs never exposed the last units to five channels at once.

  2. 02

    Event-driven propagation

    Stock changes pushed to every channel within seconds via webhooks, with idempotent retries and a dead-letter queue so a marketplace API outage never lost an update.

  3. 03

    Settlement reconciliation

    Automated import and matching of marketplace settlement files against orders, surfacing fee discrepancies and short payments as an exception report.

  4. 04

    Returns loop

    Return receipt tied to condition grading, automatically restocking sellable units and writing off the rest.

We found short payments in the first month that more than covered the project.
