Track Every Last-Time-Buy Window Across Your BOM

Z2 runs a live countdown on every last-time-buy part in your BOM and sizes the recommended buy from your demand forecast, so a missed deadline never forces a redesign.

Überblick

When a manufacturer announces a last-time-buy, you have a fixed window to place a final order before the part is gone for good. The Last-Time-Buy Window Tracker monitors that countdown on every affected component in your BOM and turns each PCN into a recommended buy quantity built from historical consumption and your forward demand forecast. Alerts escalate as the close date nears, and an executive view rolls total exposure and estimated spend across every product line, so no window slips past and no buy is guessed.

Never miss a last-time-buy window

Live countdown on every part

As soon as a manufacturer issues a last-time-buy notice, Z2 attaches a countdown timer to each affected component in your BOM, running from the announcement to the order close date. You see at a glance which parts have months of runway and which close within weeks, ranked by urgency rather than buried in a stack of PCN emails. Because roughly 30% of discontinuations ship with no formal change notice, Z2 cross-references lifecycle signals and distributor inventory so a quiet last-time-buy still surfaces before the window shuts.

Right-sized buy quantities

A last-time-buy is only as good as the quantity you commit to, and guessing leaves you short or holding dead stock. Z2 calculates a recommended buy quantity from your historical consumption on the part and your forward demand forecast across the product lines that use it, so the order covers projected build volume through your planned design-out or end-of-program date. You adjust the assumptions and the number updates, giving procurement a defensible figure instead of a finger-in-the-air estimate.

RECOMMENDED BUY
STM32F103C8T6
STMicroelectronics, used on 3 product lines
Annual consumption 4,100 / yr
Forecast to design-out 12,500
Safety buffer +8%
Recommended buy 12,500

Escalating deadline alerts

The cost of a missed last-time-buy is a forced secondary-market buy at inflated prices or an unplanned redesign, so Z2 escalates as the close date approaches with 90-day, 30-day, and 7-day warnings routed to the owners of each affected part. An executive summary sits above the part-level detail, rolling total last-time-buy exposure and estimated spend across all product lines, so leadership can approve the capital and prioritize the windows that protect the most revenue.

Part of Part Risk Manager

The Last-Time-Buy Window Tracker is one capability inside Part Risk Manager, Z2's component risk platform. It draws on the same data layer that powers lifecycle forecasting, PCN monitoring, and supplier risk, so a part flagged as nearing end-of-life feeds straight into its last-time-buy countdown and recommended buy. That shared foundation means the demand and lifecycle signals behind every buy recommendation stay consistent with the rest of your obsolescence program.
