What's the average income of a CPA?
It really depends on your employer, your skills, your achievements, and your title, but may range from $48,000/year all the way up to $170,000/year.
You have to be more explicit on this. The cost of making a CPA or how is the average on top payng CPa offers. I guess that building a CPA website is almost the same as a simple website different with the offline registration of your company. As a average of top offers payout this can be between $1 and $100 for a sale depends of the sales ofcourse.
CPA's don't usually work in banks, they work for accounting firms. If a bank needs a CPA to perform a service, they go through the accounting firm. A finance degree is probably more appropriate for working in a bank, than an accounting degree/CPA license. Depending on experience and other factors, CPAs can make 50-100k/yr.
