-it’s a source of finance (so the business can expand, pay debts and unprecedented costs etc...)
-it motivates owners and workers by rewarding them so they’re more efficient and likely to continue on in the business
-it’s an indicator of success (owner knows their product is succeeding so it helps decision-making, competitors and stakeholders are attracted to the business)
-this one’s a bit wishy washy but I would say it rewards owners for their risk taking which also aids decision-making and motivates them
-there’s certainly more but off the top of my head! Good luck x
