Stokk records the gap between every PO sent and every receipt that followed it. From that history, each supplier gets a single reliability score — a percentage that lets you compare suppliers at a glance.
Open a supplier from Purchasing → Suppliers. The reliability score sits in the Structured Config section alongside lead time, order day, and MOQs.
The score blends several signals from the last few months of POs:
A higher number is better. Treat it as relative across suppliers rather than as an absolute pass / fail.
A low score is the cue to dig in. Check the supplier's recent POs for the pattern — is it always late? Always short? Hovering the score shows the contributing breakdown.
If the actual lead time is consistently 2+ days off the stated one, edit the SIF. The forecast and reorder calculations will start using the corrected value the same night.
