Regulated manufacturers do not get to treat lot history as optional. Whether you ship under FDA, GMP, or customer quality agreements, you need to answer three questions fast: what went into this batch, where did it go, and who touched it?

Paper travelers and disconnected spreadsheets can pass an audit once. They fail when a recall window is measured in hours, not days, and when multiple plants need the same genealogy story.

End-to-end lot traceability means every consume, produce, and ship event is linked to the same lot identity. That is how you produce a one-up / one-down report without assembling it by hand.

Swift WMS is built around lot and license-plate tracking so genealogy is a query, not a war room exercise. Pair that with document storage for certificates and you close the loop customers and auditors actually care about.
