How companies buy stuff.
You probably don't think a lot about it, but you have a purchasing system for groceries. You figure out the meals you want for the week (frozen burrito, frozen pizza, peanut butter eaten right from the jar using a Kit-Kat as the spoon, etc.). Then you make a list. If you've got roommates and/or loved ones in the house with you (pets count...otherwise, everyone here at Shmoop would lead sad, lonely lives), you have to run the list by them. Once the list is settled, you either order online, or you head out to the store.
Companies do the same thing. Because they've got a lot of MBAs on staff, they have more formalized processes. These fall under the general heading of "purchasing systems."
Essentially, the term describes how companies buy stuff, i.e. the process they go through to pick out what they need to buy (printer ink, new laptops, Kit-Kats and peanut butter for the breakroom, a fleet of corporate jets, etc.) and then the steps needed to make the actual purchases. And, because these exist, many large companies use software and other technological aids to streamline the purchasing systems.

romantic candlelit dinner that was three hundred forty two dollars in Manhattan [romanic dinner for $342]
well here it is for three dollars and forty two cents okay the basic idea here [roast pig for $3.42]
is that a dollar is not a dollar everywhere throughout history and
throughout the world inflation affects the purchasing power
of a dollar over time local wealth of a given area is also a big influence well
the demand for dollars versus a country's local currency is another
factor like when the Soviet Union fell under Gorbachev and Reagan they prized
hard currencies like the US dollar massively over their own country's ruble [one dollar bill in sky]
which kind of evaporated in value yes re there reppu Tanja's keeping it real and [russian money and Putin]
purchasing power metrics are a big thing mainly as they relate to old people who
can't really earn money on their own or at least not enough to fully pay their [coins falling down]
bills and when inflation roars while old people suffer more than other categories [lady walking down street and meets lion]
of citizen because their portfolios are usually invested in pretty safe low
interest bond that don't adjust to inflation and whose
value is destroyed in times of high inflation as their purchasing power kind
of erodes so yeah I don't be old if you can help it really makes it tough to
afford that gluten-free bread maker but you could see an advertisement for right [frazzled lady]
