When you first start a business, or if you are a small business, you will need to set up a system to keep your records. As I’ve said previously, you don’t need to have a computerised system to do this nor do you have to follow the principles of double entry bookkeeping. A single cash entry system is fine as long as you record what has come in and what has gone out of your business. Below is a simple way to keep on top of your purchase invoices:
- Get two files: one for invoices to be paid and one for paid invoices – I use a document wallet for the unpaid invoices and a lever arch file with A-Z dividers for the paid ones
- File the invoices alphabetically and then, for each supplier, by invoice date. This way you can find any invoice quickly
- When you pay (or part pay an invoice), write the date and method of payment at the top of the invoice, eg “paid 7.12.12 via internet banking”. If you paid by cheque write the cheque number as well as the fact that you paid by cheque.
- When you have paid an invoice, file it in the paid file. However, if you are paying an invoice in installments, do not file it in the paid file until all installments have been paid, keep it in the unpaid file so that you don’t overlook it when you are paying invoices next month.
Once a month, I transfer the information to a spreadsheet or computer software ready for the end of the year. Yes, I use computer software and prior to this I used a spreadsheet. This is because it is easier to breakdown the categories of income/expenditure and to calculate the profit/loss at the end of the year. If you are a limited company, your accountant will need a breakdown of the income/expenditure when preparing your accounts. If you are a sole trader, the HMRC will need a breakdown if you earn more than £75,000.
