There are three forms of business organization: the single proprietorship, the partnership, and the corporation.
A financial analysis may show that your business plans are potentially profitable, but you may nevertheless run into the problem of cash flow. This arises because you have to pay your workers and suppliers before you have a product to sell. So, even if your idea is profitable over the year as a whole, you need bridging funds to get over the initial debt. One solution is to delay paying for your supplies; however, the suppliers will charge a high interest rate -- up to 24% per annum -- for being made to wait. Or, you can talk to the bank. If you have no source of income other than your business, you do not look like a good risk to the bank, which knows that almost all small businesses fail within their first few years. So if they lend to you at all, it will be at a high rate to cover the risk.
A partner in a partnership may be a general partner, in which case he or she is responsible for all the debts of the partnership, or a limited partner, in which case their responsibility is limited to the amount of their original investment. At least one partner must be a general partner.
Forming a partnership multiplies the talent the firm can draw on, and multiplies its capital (though if none of the partners has any capital, this doesn't help much.) An established company may offer partnerships to particularly promising employees, motivating them to stay by giving them a share in the equity.
On the other hand, partnerships can lead to disagreements. Once the partnership is formed, your partners are legally entitled to share in the profits, even if you've been doing all the work.
Corporations are of two kinds, public and private. The difference is in whether the shares can be publically traded.
Once you decide to sell stock, you will probably need to recruit someone to market it for you. This would be an investment banking firm, and they will generally take a cut of the sale price to pay for their efforts -- how big a cut depends on how strong a bargaining position you have. If you are a big company, the banker may agree to underwrite your stock, that is, guarantee to buy all you have to sell.
There is no limit to how much stock you may decide to issue to yourself, in recognition of your contribution of talent to the corporation. However, you are required to provide an independent audit of the firm's accounts to stockholders. In the United States, the Securities and Exchange Commission oversees stock issues, and checks for misleading claims. (The Vancouver Stock Exchange is notorious for lax oversight.)
The advantages of incorporating include limiting your personal liability and acquiring capital. The disadvantages are that it costs money to incorporate, that you are obliged to disclose possibly sensitive company information in your annual report, and you risk losing control of the corporation to a takeover bid.
Several diagnostic tests may then be applied to these data:
The Current Ratio is the ratio of current assets to current liabilities. The desirable level for its absolute value varies from one industry to another, but its year-to-year change indicates whether the business is getting into trouble.
Working Capital is the excess of current assets over current liabilities
The acid-test ratio is the ratio of cash and accounts receivable to current liabilities. The point of this test is that cash plus accounts receivable are immediately realizable as cash; inventory, the other item included in current assets, may be difficult to liquidate, and hence may give a misleading sense of security.
Lastly, the rate of return is an important diagnostic; but by this stage, we know
all about that.
