01Define when the clock starts
Ask what must happen before preparation begins. The starting point may be order confirmation, payment, artwork approval, sample approval or receipt of packaging materials. Record the agreed trigger instead of assuming the inquiry date starts the lead time.
02Separate ready date from dispatch date
A product-ready date means the goods are prepared for the next step. Packing, inspection, export documents and carrier collection can require additional time. Request both the estimated ready date and the estimated dispatch date.
03Match the estimate to the exact order
Quantity, color mix, packaging, labeling and customization can change preparation time. Ask for the estimate against the exact product reference and order scope rather than using timing from a different version or earlier quotation.
04Treat freight as a range
Transit estimates can change with route, service level, handovers, customs and local delivery. Record the shipping method, the quoted range and what event counts as delivery completion. Do not turn a carrier estimate into a guaranteed arrival date.
05Plan backward from the retail date
Start with the date stock must be available for sale. Work backward through final delivery, customs, freight, dispatch, packing and preparation, then add a contingency window that reflects the cost of arriving late.
06Refresh the timeline before a reorder
Do not reuse an old lead-time estimate without checking it. Quantity, packaging availability, production load, route conditions and the requested delivery window may have changed since the previous order.
