How to Manage Production Transitions Between Old and New LED Mask Models
We launched Version 2 of our LED mask. Version 1 was still selling well. We announced Version 2, and Version 1 sales stopped immediately. Customers wanted the “new and improved” version. But Version 2 wasn’t ready for production for 8 weeks. We had 6 weeks of zero sales, $47,000 in lost revenue, and a warehouse full of Version 1 masks we had to discount to clear.
Product transitions are a classic cash flow trap. Here’s how to manage them without the gap.
The Transition Timeline
A well-managed transition has overlapping availability.
| Phase | Timing | Action | Inventory Status |
| Phase 1: Announcement | T-8 weeks | Announce new version, pre-orders | Old version available |
| Phase 2: Pre-order period | T-8 to T-2 weeks | Take pre-orders, collect deposits | Old version available |
| Phase 3: Production overlap | T-2 to T+4 weeks | Produce both versions | Both available |
| Phase 4: Old version phase-out | T+4 weeks | Discontinue old version production | Old version available while stock lasts |
| Phase 5: New version only | T+8 weeks | Old version sold out or clearance | New version only |
The mistake we made: We announced Version 2 and immediately discontinued Version 1. The 8-week production gap killed our revenue.
The fix: Never announce a new version until you have inventory of the new version ready to ship within 2 weeks. Or keep the old version available as a “budget” option alongside the new version.
The Inventory Bridge Strategy
How to avoid the gap:
| Strategy | Implementation | Pros | Cons |
| Produce old version until new version is ready | Maintain old version production until new version inventory = 2 months of demand | No gap, no lost sales | Higher inventory carrying cost |
| Pre-order model | Take pre-orders for new version, produce after pre-orders hit MOQ | No inventory risk | Pre-order customers wait |
| Parallel production (short run) | Produce small run of new version while old version still in production | Both available simultaneously | Higher per-unit cost (small run) |
| Old version clearance before launch | Discount old version to clear inventory before new version launch | Clean break | Lost margin on old version |
Our recommendation: Parallel production for the first 500-1,000 units of the new version while old version is still in production. This gives you inventory to ship immediately when you announce, and old version remains available for price-sensitive customers.
The Customer Communication
How to announce without killing old version sales:
| Message | What to Say | What NOT to Say |
| Announcement | “Introducing Version 2 — with X, Y, Z improvements” | “Version 2 replaces Version 1” |
| Old version positioning | “Version 1 remains available as our budget-friendly option” | “Version 1 is discontinued” |
| Upgrade path | “Existing Version 1 customers get 20% off Version 2” | “Version 1 is obsolete” |
| Availability | “Version 2 ships in 2 weeks. Order now to secure yours.” | “Version 1 is sold out” (if it’s not) |
The key: Position the old version as the “budget” or “essential” option, and the new version as the “premium” or “advanced” option. Both can coexist in the market. This prevents the immediate sales stop that happens when customers think the old version is “obsolete.”
The Component and Tooling Transition
The production transition affects more than just the final product.
| Component | Transition Strategy | Cost Impact |
| Shared components (power supply, LEDs) | Continue using in both versions | $0 (no impact) |
| Version-specific components | Phase out gradually as old version inventory depletes | Minimal (already purchased) |
| Tooling (molds) | Keep old tooling for spare parts production | Storage cost ($200-500/year) |
| Packaging | Use old packaging for old version, new packaging for new version | Minimal (already printed) |
| Documentation (manual, IFU) | Maintain both versions until old version is out of market | Translation cost for new manual |
The spare parts commitment: Even after discontinuing the old version, you need spare parts for warranty support (typically 2-5 years after last sale). Keep the tooling and produce spare parts in small batches (50-100 units) as needed.
The Pricing Strategy During Transition
| Scenario | Old Version Price | New Version Price | Strategy |
| Old version still available | $149 (reduced from $179) | $199 | Old = budget, new = premium |
| Old version clearance | $129 (clearance price) | $199 | Clear old inventory fast |
| Old version sold out | N/A | $199 | New version only |
| Both available long-term | $149 | $199 | Two-tier pricing strategy |
The mistake: Discounting the old version too aggressively before announcing the new version. If customers see a “50% off” sale, they’ll wait for the discount and not buy at full price. Time the clearance discount to coincide with the new version launch.
What We’ve Learned
1. Never announce a new version until you have inventory ready to ship within 2 weeks. The 8-week gap between announcement and availability cost us $47,000 in lost sales. Customers stopped buying the old version immediately, but the new version wasn’t ready.
2. Position the old version as “budget” alongside the new “premium” version. Both can coexist. The old version at $149 serves price-sensitive customers. The new version at $199 serves customers who want the latest features. This prevents the sales stop.
3. Parallel production for the first 500-1,000 units of the new version. Don’t shut down old version production until new version inventory = 2 months of demand. The slight increase in inventory carrying cost is negligible compared to lost sales.
4. The spare parts commitment affects tooling decisions. If you discontinue a version, you still need spare parts for 2-5 years. Keep the molds and produce spare parts in small batches. The $200-500/year storage cost is cheap insurance.
5. Clearance discounts should coincide with new version launch. If you discount the old version 2 months before launching the new version, customers will wait for the discount. Time the discount to start when the new version becomes available. This clears old inventory without losing full-price sales.
Managing production transitions between old and new LED mask models requires overlapping availability, careful customer communication, and a pricing strategy that positions both versions in the market simultaneously. Never announce a new version until you have inventory ready to ship within 2 weeks. Keep the old version in production (or available from inventory) until new version inventory equals 2 months of demand. Position the old version as “budget” and the new version as “premium” so both coexist. And plan for spare parts production for 2-5 years after discontinuation — keep the tooling and produce spare parts in small batches as needed. The goal is zero gap in availability and zero lost sales during the transition.
