Buying a Business: Opening the Books and First-Year Records

Buying an existing business gives you customers and equipment, but also a record-keeping job that begins on closing day. How the purchase price is divided among assets can matter for tax. That allocation is negotiated and documented by your attorney and CPA. Your books must then follow it faithfully.

Quick answer. When you buy a business, keep the purchase agreement, closing statement, asset list, allocation schedule if there is one, loan documents, bills of sale, lease assignments and any seller financing note. Record the exact closing date; everything in your books should trace to these papers.
