What is bookkeeping?
Bookkeeping is the first stage in Accountancy, it is the recording of financial transactions within a business.
You are recording all of the income and expenditure that relates to your business, the source documents you need to record this information from are:
Sales invoices
Purchase invoices
Credit notes
Receipts for cash based purchases
Bills received from utility companies
Petty cash vouchers
Paying in slips
Cheque book stubs
Statements of account (Bank Account etc)
Register of payments by standing order or direct debit
The payroll
It is a legal requirement that these documents need to be kept for a minimum of 6 years. The information on these documents are recorded either on a spreadsheet or in bookkeeping software. If you are a very small business a spreadsheet will suffice. For a larger business with lots of transactions you will be better of using some bookkeeping software.
You need this information to work out your VAT and Corporation Tax. You can work out the profit of your business and always have up to date information on who you owe money to and who owes money to you. This information will help you make informed business decisions.
Filing your paperwork
I would suggest keeping digital copies of all of your paperwork so that you have it to hand without having to dig through arch lever files. HMRC accepts digital format. You can keep hard copies of your documents, this is down to you to decide if you want a digital filing system, a hard copy filing system or both.
