Don't Assume A Customer Who Uses Financing Can't Afford What They're Buying
In many cases the opposite is true. Smart customers will use financing so that they can make their money work for them, by putting it in an interest-bearing account, an investment that earns dividends, etc.
For example, a customer who could easily afford a $5,000 bike may instead choose to use 12-month financing so that they can get their bike now while earning interest or dividends on that $5,000 over the course of the year. They will make the required payments each month, pay off the balance at the end of the 12 months, and now have extra income earned on that $5,000 by not having spent it in one lump sum.
