The lead time is the most useful field

It tells you when to order so that goods do not run out.

Set the item minimums from it

A supplier with a 14-day lead time needs a higher minimum quantity than one who delivers overnight. Without that you run out exactly when demand is highest — see Stock items.

The lead time can also feed into the delivery estimate a customer sees for goods that are currently out of stock.

The default supplier on an item

The stock item records who the item is usually bought from. It is then pre-filled on a receipt.

It is a default, not a restriction

Nothing stops you receiving the same goods from a different supplier — you simply pick another one on the receipt.

Disabling

With the Aktivní toggle. The supplier stays, receipt history included; it is simply not offered on new documents.

Do not delete a supplier with history

Receipts refer to them. After deletion it would be impossible to trace where goods came from — which is exactly what you need when claiming against a supplier.
