A monthly income statement for at least the first year of operations should be part of your business plan. For the succeeding years, the projected income may be less frequent, owing to the fact that monthly estimates far into the future may not be that credible (It's really difficult to project financial performance past the first year of the business).
Do also take note that when doing record keeping, it pays to know the difference between cash and accrual accounting systems. Under the cash method, transactions are recorded when money changes hands. For instance, a sale recorded when income is received. Expenses and purchases are recorded when they are paid. This is quite simple and suited for small start ups with no inventory. Under the accrual method, transactions are recorded as they are made. For example, a sale is recorded when the customer is billed with an invoice. Purchases are recorded when the supplier sends the bill. Businesses with inventory and large enterprises are the usual followers of the accrual method. For start ups, one can get free online accounting to help with your business accounting needs.
