Sumtracker is the 1:1 Stocky-shape replacement. LineNow is what Stocky should have become.
Sumtracker is an inventory database with multichannel sync and PO generation, built for Shopify and other e-commerce platforms. LineNow is a closed-loop procurement platform built around a living purchase order — the buying workflow runs from one connected operating record, including reading the supplier's reply and updating inventory itself.
Sumtracker is one of the more frequently named Stocky alternatives in 2026, especially for operators who want a Stocky-shaped replacement. It's a competent product in its category. Sumtracker covers the same ground Stocky did — inventory database with multichannel sync and PO PDFs. LineNow covers that ground and adds the living PO loop on top.
