How to plan pool chemical reordering

Measure average weekly use, convert supplier lead time to weeks, add a safety-stock allowance and reorder before stock falls below that combined requirement.

Reorder point = weekly use × (lead-time weeks + safety-stock weeks)

Use observed consumption

Season, weather, pool mix and service scope can change purchasing needs. Update weekly use from actual records rather than a fixed guess.

Choose safety stock deliberately

Extra stock can protect the route from delivery delays, but excessive inventory ties up cash and can create storage concerns.

Keep treatment decisions separate

This tool plans purchasing only. Follow labels, safety procedures, storage requirements and applicable regulations.

Frequently asked questions

How is the reorder point estimated?

Multiply observed weekly use by supplier lead time in weeks plus selected safety-stock weeks.

What is safety stock?

It is extra inventory intended to cover demand or delivery variability.

Does this tool recommend dosing?

No. It only plans inventory from usage entered by the user.
