What growing producers are up against.
Built for lot traceability software.
Append-only event ledger
Every receive, inspect, produce, package, ship, and hold writes a who/what/when/where/why event - the genealogy and recalls are projections of it.
Forward & backward trace
Trace back from any finished lot to its materials and suppliers, or forward from any material lot to every batch, finished lot, and customer.
Interactive genealogy graph
Explore the full lot graph visually; click any node for a drawer of facts and its complete event history.
Live activity timeline
Every record carries a live timeline drawn from the ledger, so the story behind any lot is always visible.
One connected chain, receiving to shipment.
Log each incoming supplier lot with quantity, expiration, and COA status - the lot lands in quarantine until it's inspected and approved.
Start a batch and consume exact approved lots. LotThread blocks anything on hold, expired, or short before it enters production.
Turn a completed batch into finished lots with traceable lot numbers, quantities, label versions, and best-by dates.
Track remaining quantity, location, expiry, and hold/release state so you always know what's clear to ship.
Record customer shipments with the same guardrails, closing the chain from supplier lot to the customer who received it.
Outcomes producers feel right away.
Questions about lot traceability software.
What does "append-only event ledger" mean for me?
It means records aren't overwritten - every action adds a timestamped event. So the genealogy and any recall scope are computed from what actually happened, and the full history stays intact and exportable.
Can I trace both forward and backward?
Both. Trace forward from a supplier lot to every customer who received affected product, or backward from a finished lot to every material and supplier behind it.
Do I have to replace my accounting or ecommerce tools?
No. LotThread is the traceability layer that sits alongside QuickBooks, Shopify, and the tools you already use - it connects your materials, batches, and shipments into one record without replacing your books or storefront.
How long does it take to trace my first product?
Most producers trace a first product in an afternoon. You set up one product, one supplier, and one production batch, and the genealogy and recall scoping compute from there - no manufacturing ERP rollout required.
Can I import existing lots from a spreadsheet?
Yes. Map your columns once and bulk-import materials, suppliers, and existing lots from a spreadsheet or supplier file, so you start with your real history instead of a blank system.
