What minimum stock is

Minimum stock is a product quantity that triggers replenishment. Calculate it from daily sales and supplier delivery days. Below it, you risk selling unavailable goods.
It makes buying rule-based instead of panic-based. Without it, someone notices an empty shelf after sales are lost. In June, when festival products move for only three weeks, panic can cost the entire season.
How to calculate minimum stock
Two basic parts:
- Average daily sales. Total the last 30 days and divide by 30. For seasonal products use the same period last year.
- Replenishment lead time. Days from supplier order to shelf, including picking and transport.
Minimum stock = daily sales × lead time. Four popcorn corn packs daily and five-day delivery means 20 packs. Order when stock reaches 20.
Add a buffer for late suppliers. Two extra selling days usually suffice: here the minimum becomes 28.
What minimum stock cannot solve alone
It does not notify. A spreadsheet number works only if checked daily. Busy weeks prevent that. A system must compare balance to minimum and notify when crossed.
It cannot fix incorrect inventory. A system showing 30 while the shelf holds 12 alerts too late. Periodic counts belong to the same process.
What to do now
Calculate minimums for ten bestsellers. If nobody opens the spreadsheet during busy times, a system can compare and notify automatically. Leave spreadsheets without losing history: avilaops.com/sistema-para-pequenas-empresas or WhatsApp: wa.me/5517997811471.
Frequently asked questions
Are minimum stock and reorder point the same?
Textbooks distinguish them: minimum stock usually means safety stock; reorder point triggers purchases. Small businesses often call the reorder point minimum stock. This guide uses that everyday meaning.
How do I calculate seasonal minimums?
Use last year’s same-period sales, not annual averages. Set before the season, with June supplier lead times that may exceed April’s.
Do I need a system?
Few products with daily morning checks work in spreadsheets. Dozens of items or simultaneous physical and online sales need systems to avoid selling sold-out items.
