Ask for dates and stage boundaries
A quoted production lead time may begin only after sample approval, artwork release or deposit receipt. Confirm the trigger for each stage and retain the supplier reference. A production interval alone is not a complete delivery plan.
Record qualification, approval, production, transit and receiving as separate sequential intervals. If stages genuinely overlap, document a separate scheduling scenario rather than silently subtracting the overlap.
Use the calendar that matches the quote
Five business days counted backwards from Monday 12 October 2026 gives Monday 5 October when no holidays are entered. Five calendar days gives Wednesday 7 October. The difference changes when work needs to start.
The tool excludes weekends and only the holidays you enter. It does not infer factory shutdowns, local holidays, customs delays or supplier availability. Confirm those in the quote and add an explicit buffer.
Put the requirement in the RFQ
Include the required-on-site date and receiving location alongside the SKU revision and good-output requirement. Ask suppliers to state their approval cutoff, quoted production trigger, dispatch date and delivery assumptions.
Use the schedule as a reviewable plan, not a promise of availability. A date outside the feasible qualification window requires a revised specification, timeline or supplier commitment.
Common questions
Can I treat the example durations as industry averages?
No. They are illustrative inputs; replace them with confirmed stage intervals.
Is this the same as a stock reorder point?
No. The deadline planner works backwards from a needed date. A reorder point uses demand, inventory and lead-time assumptions to estimate when replenishment should be triggered.
