In standard business plan financials, the balance sheet is a projection, not a recounting of actual money. It links to projected Profit and Loss to help project cash flow. It’s the most important example of the difference between planning and accounting. In accounting, the Balance Sheet statement has exact details broken into categories and sub categories. In business plan financials, the Balance Sheet projection is necessarily summarized and aggregated. In the illustration here, I point out an example in numbers.
This means that your balance sheet categories should be summary categories from your accounting. For example, assets categories are probably only Cash, Accounts Receivable, Inventory, Other Current (or Short-term) Assets, and Long-term Assets (or Plant and Equipment). Liabilities are probably only Accounts Payable, Income Taxes Payable, Sales Taxes Payable, Short-Term Debt, and Long-term Liabilities. Capital is only Paid-in Capital, Retained Earnings, and Earnings.
There are two good reasons for this:
In contrast to the Projected Balance Sheet, the Balance Sheet as a financial statement is a compiled report drawn from a database of details. Accounting knows each transaction: exactly when each asset was purchased, for how much, and its depreciation history and schedule. Accounting knows each loan (called notes) history. Every detail in the statement is based on actual transactions. It goes into tax reports and legal reporting. The projection, on the other hand, is a collection of educated guesses that help you plan your financial needs in advance.
Handling of depreciation is the best example. The accumulated depreciation in a Balance Sheet Statement is a summary of detailed depreciation for each asset the business owns. It comes from the depreciation in the Profit and Loss Statement, which is compiled from the detailed depreciation of each asset. Tax code defines allowable depreciation schedule for each asset according to type, so for example, buildings are normally depreciated over 30 years, while vehicles might be over three or five years. Depreciation in a Projected Profit and Loss, in contrast, is an estimated guess of an aggregated future amount. A good forecaster will look at depreciation over the recent past, plus projected purchases of new assets, to estimate future depreciation. That estimate ends up in the Balance Sheet as Accumulated Depreciation, which subtracts from the value of Long-term Assets.
