Finance partners rarely object to charts. They object to charts that change meaning when someone asks which date was promised.
In our Hong Kong engagements, the most durable vendor lead-time reporting packs include a one-page definition sheet signed off by buying and finance before any visualisation is drawn.
Three dates to keep apart
- Commercial promise — the date the vendor committed in the PO or confirmation email.
- Freight milestone — vessel departure, arrival, or customs release, depending on Incoterms.
- Operational receipt — when goods are available to your warehouse or cutting floor.
Lead-time slip should name which pair you are comparing. “Late versus PO promise to warehouse receipt” is a sentence finance can audit. “Late in general” is not.
Why this matters for cover
If safety stock models use receipt-based cover while buyers chase freight milestones, the same shipment looks healthy in one report and late in another. Aligning definitions is unglamorous supply chain analytics — and it prevents weeks of circular debate.
