Are my sales figures and supplier lead times saved or sent anywhere when I use the reorder point calculator?

Why the question matters at all

The numbers you enter are not ordinary. Your average daily sales reveal how big a product really is for you, the lead time says something about your supplier and how quick they are, and the safety stock shows how much you keep on the shelf. A competitor who knows you sell 40 units a day of a product and that your supplier needs 7 days knows a lot about their chances against you. So it is reasonable to ask where those figures go.

What actually happens when you type

The maths is simple multiplication and addition running in the page itself. When you open the calculator, a sample is already loaded:

There is no login, no user account, and no link to your Salla, Zid or Shopify store. The calculator keeps no history of what you worked out; reload the page and the fields go back to the sample.

What stays your responsibility

• 'Copy result' puts the inputs, the result and the assumptions on your device's clipboard. Watch where you paste it, especially in group chats.
• On a shared computer in the warehouse or office, close the tab or reload the page when you finish.
• The sheet where you keep each product's reorder point is the truly sensitive file. Protect it like the rest of your business data.
• When you send a purchase order, the supplier sees the quantity you order, which is normal, but there is no need to send your stock calculations with it.

A comfortable, safe routine

1. Keep daily sales, lead time and safety stock for each product in your own sheet.
2. Open the Inventory reorder-point calculator, enter the product's figures, and copy the result into your sheet.
3. When stock reaches the point, prepare the purchase order with the Purchase-order generator, which also runs in your browser.
4. Log each order's cost in the Expense summary generator if you want to follow stock spending month by month.
