Choose the quantity you can count
Count sealed packets and read the sheets per packet. Add an estimate for an opened packet only if you mark it as an estimate. Avoid counting the same packet in both sealed and opened inventory.
Separate forecast from reality
A trip, visitors or a change in routine can alter consumption. Refresh the assumption with your own observations. Our tool does not infer a daily requirement from a child’s age, weight or skin condition.
Allow for delivery uncertainty
The lead-time field is a user assumption, not a live merchant promise. A scenario can show whether your assumed stock covers that period. It cannot verify local availability or guarantee that an order arrives in time.
Before you decide
- Count actual stock
- Enter your own use assumption
- Recheck delivery timing
