Like other forms of self-employment, home-based businesses face a number of challenges relating to financial management and tax compliance. Part of the business plan that is prepared prior to forming a home-based business is a financial plan detailing how much it will cost to begin the new venture and keep it running. After the business has been established, it is vital that the entrepreneur set up a good bookkeeping system to manage cash flow and ensure compliance with tax laws. Bookkeeping systems can be manual or computer based. Experts also recommend that entrepreneurs set up a separate checking account for their home-based businesses in order to better document business expenses. Canceled checks, paid bills, invoices, sales slips, receipts, and other financial documentation should be kept on file in case of an audit. Another important aspect of financial planning for a home-based business is tracking working capital—the difference between current assets (cash, accounts receivable, and inventory) and current liabilities (operating expenses, debts, and taxes)—in order to maintain a realistic picture of where the business stands financially.

With whom do you want to do business? Be as specific as you can. Identify the geographic range and the types of businesses or customers you want your business to target. If you don’t know whom you want to do business with, you can’t make contact. “You must recognize that you can’t do business with everybody,” Falkenstein cautions. Otherwise, you risk exhausting yourself and confusing your customers.

It’s one of the oldest and most proven ways to make money – buy low, sell high.

In this way, you might be able to acquire an item for $5, and later sell it for $50.
Concentrating all marketing efforts on a small but specific and well defined segment of the population. Niches do not 'exist' but are 'created' by identifying needs, wants, and requirements that are being addressed poorly or not at all by other firms, and developing and delivering goods or services to satisfy them. As a strategy, niche marketing is aimed at being a big fish in a small pond instead of being a small fish in a big pond. Also called micromarketing.
