A box that lasts three weeks can still run out on a weekend if the order date is never counted.
Turn strips on hand, daily use, lead time, and a buffer into the day to place the order.
Anyone who uses test strips regularly and wants to order before the supply runs short.
Use the source document or official route that applies to your situation. This guide does not contact another person or verify external information.
Count the sealed strips on hand. Do not count an opened box you cannot verify.
Take the strips a day from your routine. Do not use the lowest possible number.
Ask the supplier how many days an order takes, including weekends.
Add a few days for a late delivery or a failed order.
If the result is zero or less, the App says to order now.
One hundred strips at four a day last 25 days. With a seven-day lead time and a five-day buffer, order in 13 days.
Use your own source and details. The example is not a record about a real person or organization.
Two supply positions. Both are examples.
Both cases are examples, not records about a real person. The bars show the same numbers the free App computes.
