Prestige
Sell factory: when to prestige
Selling the factory is the prestige. You keep permanent upgrades. You lose machines and weapons. The children-fed counter goes back to zero.

The mail gate
Tanya's route: own the Uzi and clear When Money Was the Problem, own the AK-47 and clear Excellent Work, then accept An Offer You Can't Refuse. Only then does Sell Your Factory appear. Filling the skill tree does not unlock the button by itself.
The quote depends on factory value, and the game shows the gears before you confirm. Published samples, not a formula: a first sale around 125 gears, a second around 160, a third around 275, and other players waiting until 1,000 or 1,600. There is no published formula from factory value to gears. I am not inventing one.
| Kept | Lost |
|---|---|
| Permanent upgrades | Machines |
| Gears you just earned | Weapons |
| The achievement A Fresh Start, the first time | Children-fed progress |
Feed children before the first sale
World's Greatest Humanitarian needs 100,000 children. The sale resets that counter. Guides that chase both achievements feed first and sell second. The Perfect Employee needs every permanent upgrade, which needs several sales, so the feeding achievement is easier before sale number one.
FAQ
When should I sell?
After the mail is accepted, after you have seen the gear quote, and after 100,000 children if you still need that achievement.
Do I lose Cold Storage?
No. Cold Storage is permanent. The machines you bought with cash are what disappear.
