30–60–90: Your Inventory Optimization Plan for the Next 90 Days

If your cash feels “stuck on the shelf,” you don’t need another spreadsheet, you need inventory optimization that actually moves the needle. Think of it as a simple rhythm: the right stock, in the right place, at the right time, for the right cost. Below are four quick wins you can roll out fast.

1) Forecast with intent (not ego)

Great planners don’t guess; they bracket. Keep a rolling 12–18 month view with three scenarios: base, upside, downside. Do a 30-minute weekly “forecast huddle” to review variances and log one action per variance.

This alone reduces uncertainty and lower uncertainty = less safety stock. That’s inventory optimization 101.

2) Segment SKUs with ABC/XYZ (focus where it pays)

Not all SKUs deserve equal love.

• ABC = value contribution (A is your money-makers, C is the long tail).

• XYZ = demand variability (X stable, Z lumpy).

AX items get tight control and frequent reviews; CZ can be simpler or even made to order. Align service levels by class (e.g., AX 98–99%, CZ 90–92%). This is the steering wheel of inventory optimization.

3) Set Reorder Points & Safety Stock to match service goals

Make math serve the mission.

• Safety Stock = z × (demand variability during lead time)

• ROP = Lead-Time Demand + Safety Stock

Revisit lead times quarterly (stale lead times wreck ROPs), and tweak by class. Clean, class-based ROP/SS shrinks working capital without gambling customer experience, a core win in inventory optimization.

4) Right-size lot sizes (EOQ vs MOQ without the drama)

Order too often and you bleed freight/handling; order huge and you inflate carrying cost. Use EOQ to set a baseline, temper with MOQ, truck/container fill, and shelf life.

For low-value, slow movers, try periodic review; for high-value movers, use continuous review. This keeps average on-hand lean while protecting service.

The other 4 strategies (teaser)

When you’re ready to level up, the full guide covers:

• Lead time compression & supplier collaboration (safety stock slasher)

• Warehouse flow & cycle counts (physical discipline → digital truth)

• S&OP drumbeat (sales, supply, finance rowing in sync)

• KPI instrumentation & safe automation (exception-led planning, not inbox chaos)

Why this works

These four moves create a flywheel: better forecasts → smarter classes → tighter ROP/SS → leaner orders. Stack on the next four and you’ve got repeatable inventory optimization that frees cash, cuts stockouts, and calms firefighting.

Software matters

Doing all this in isolated sheets is pain. If you want it operationalised, iFive ERP rolls it into one workflow : ABC/XYZ automation, nightly ROP/SS/EOQ proposals, exception dashboards, barcoded receiving, guided putaway, and cycle counts.

With AI demand sensing, it flags early shifts so you act before issues explode. If you’re hunting for the best ERP in Chennai, start here.
