- Online sellers pricing inventory across resale platforms
- Worth noticing
- The lot-cost calculator allocates a box purchase across items and calculates an acceptable minimum offer.
Field notes
Each platform calculator exposes the fee model it applies: eBay's final-value and per-order fees, Poshmark's under-$15/20% split, and Mercari's selling and processing fees; users can also enter custom rates. A separate lot tool divides a box or lot cost among its items. The site also lists two downloadable Excel/LibreOffice workbooks, priced at $15 and $16 on Gumroad, for inventory tracking and lot pricing.
