There's two situation,
Every morning of the day, or at the beginning of the week, the shop manager would choose several bags(Birkin/Kelly) and tell the salesmen, these are the bags we could sell today/week. So normally we don't need to ask the manager for these bags. But actually they ask, because they don't want any trouble afterwards.
The other situation is every month or week, the shop manager pick several bags, and tell each salesman" you can sell these bags this week/month". And the salesman don't need to ask the manager before he sells, even the client doesn't purchase anything else. It varies from shop to shop that the quota they can sell every month. Normally a small shop like us we can sell 40-50 Birkin/kelly per months. But for FSH, it's totally different, I've heard that one salesman could achieve 100,000 euro sale in one day which is incredible for some small shops like us. So surely they have bigger amount for bags.
Oh, there's another situation, that only happens in big shops with different department managers. The shop manager choose some bags for every department, and the department manager can decide themselves to whom they sell. And the salesman always need to ask their department director for sell a bag as they are not allowed.
In any case above, there's always a budget we need to achieve, so we have to think how to achieve the budget with the use of limited bags, same for a department manager or for a salesman in small shops. Even for a shop manager, if a shop makes a huge sale, he can have bigger quota for bags when the podium
PS. Mini Kelly pochette/ Kelly cut pochette/ HAC are all included in these quota.
Not the Constance.
And every manager keep the stock into two parts, one for himself( the bags only could be sold by himself) and one for the shop staff. And stock for himself include exceptional pieces, exotic leather or special orders. If you enquire such a piece, the salesman have to ask the manager for that.
