PFSRD: NPC Shop Wealth???

[OGDojo]

so I'm curious cuz I can't seem to find rules for it. how much money should a shop owner have on hand for purchasing items? Some DMs let players sell anything from a piece of chalk all the way up to a +5 magical weapon at any town or city in the world they are in, that doesn't seem like a good solution. a gem shop owner might have several thousand on hand so they can purchase some of the more expensive pieces however a black smith or a tailor might only have 5-10 gold pieces in their whole store. obviously a jeweler would have more security where the tailor might have a pet dog that may or may not sound the alarm if you sneak in. my question, is there a list or a document somewhere that lists how much money shops keep on hand for buying items from players so that the players have to wait for bigger cities to get a decent price on magical equipment?

here is kinda what i was thinking and you can decrease it for smaller places like villages of 30 people obviously wouldn't have 500gp or more on hand

Not on a shop level, no. Settlements have a purchase limit based on settlement size. So, for example, a small town of 200-2000 people will carry magic items up to 1000 gp value, buy ones up to 5000 gp. Look up pathfinder settlements on your search engine and you will find the chart.

Remember: a magic item shop should have security commensurate to the treasure value within.
