How does investing work for settlements?

[Human Person]

I was wondering how investing works for settlement merchants. When I got the perk I wanted it for the tier 3 merchant caps, but when I discovered investing I invested in a few settlement merchants before it stopped working, so how does it work?

Without investing a merchant will typically have ~250 ish caps to barter with. Bars may have less. After you invest in the shops, you raise the merchants availible cap reserve, so they have more and can trade more, so you get more caps pr rest cycle.

That perk makes it good for getting materials to build with.

I used this perk to pay for all my robot workbench modding.

investing is only needed once per kind of settlement vendor, means if you invest in one of your settlement weapon vendors, all settlement weapon vendors in all settlements get the investment, because all use the same cash and item pool. exeption are some of the lvl 4 special vendors becasue they use there own pools.

Ah, thank you.
