3D seller system · SELLER-01

Run your asset listings like a portfolio, not scattered uploads.

One editable Excel workbook for the listing pipeline, pack economics, release calendar, media/QA and real sales history.

Listing pipeline

Track SKU, marketplace, status, priority, price, discount, fee assumptions and launch date.

Pack economics

Estimate production cost, net revenue, contribution, break-even units and projected ROI.

Release + QA

Keep publishing tasks, blockers, media requirements and product checks in one workflow.

Also included

  • Seller Dashboard with marketplace KPIs
  • Sales Log for units, gross, fees, refunds and net sales
  • Quick Start PDF
  • Personal & commercial business-use license
  • Sample rows so the workflow is visible immediately

Built for real marketplace work

The workbook is useful whether you sell model singles, environment packs, creator templates or other game-dev assets. It does not depend on one marketplace, so you can compare Fab, itch.io, Ko-fi, Unity Asset Store, your own site or another channel without rebuilding the workflow.

Important limitation

This is a planning and tracking aid. It does not guarantee marketplace acceptance, rankings, traffic, sales, profit, legal compliance, tax treatment or license compliance. Verify each platform's current fees, payout rules and product policies.
