If you were starting a business, then the intuit answer works, but in your question you are buying a business, that is different.
when you buy a business you are buying things, assets, receivables, debts, etc so you first need the business balance sheet to determine what you are buying and the value of each. Then you use your money to "buy" those things at that balance. Any of the purchase price that is left over is booked to an asset account called goodwill.
Deposit the total amount in a cash type account, and use that account to "buy" the parts of the business.
