Label A items as revenue‑critical parts with tight reorder points, B as supportive components, and C as embellishments. Calculate minimums from real lead times, not hope. Protect peak months by ordering A items earlier, even if it means pausing experiments until cash refills.
Track how long it takes to switch colors, molds, or fixtures. Smaller batches reduce work‑in‑progress and free cash, even if setup repeats more often. Identify the true bottleneck and protect it with scheduled focus blocks, protecting delivery promises and keeping inventory from swallowing your checking account.
Reserve make‑to‑stock for steady sellers with short shelf lives and dependable margins. Keep custom or risky styles make‑to‑order with deposits. Blend the two seasonally. When each product has a clear approach, materials flow predictably, overtime drops, and cash no longer disappears into stacks of unsold experiments.
