When you estimate the cost of any equipment and tools you need, bear in mind that professional quality tools are considerably more expensive than DIY ones. Although the two often look similar, you can expect a professional quality tool to outlast a DIY 'equivalent' many times over. It will probably also perform better. It is this superior build quality that you are paying for - the tool will be designed to be used hard every day, rather than just once in a while. Of course, you could decide to buy cheap and replace frequently, but remember that it is your valuable time that will be wasted when a crucial tool packs up.
Don't forget to include any expenditure such as having your logo and livery put on your vehicles. Think about any extra vehicle security you need too.
If you are paying cash for all the items you are buying for your business, enter the amounts - including VAT - in the months when you expect to pay for them.
If you decide to buy some items on hire purchase, or with a loan, enter the deposit and the monthly payments in the months in which you will pay them. These payments will be made up of both capital and interest. Enter the capital here and the interest under 'Bank/finance charges and interest' in your cash flow. The agreement will identify the amount of interest payable annually - if you deduct this from the total amount you have to pay each year the balance is the capital.
