Business Expenses - Keeping a record of expensable monthly bills

Katie_Scln

Hello,
I'm new to the self-employment world (recently registered as Sole Trader) and am currently trying to practice good habits in regards to bookkeeping from the get-go to avoid a meltdown come January.
I'd like to know how I keep a record my monthly Website Hosting fee so I can expense it for my tax returns.
1-I'm charged the same bill, of the same amount monthly. Do I therefore have to keep each individual bill every time I'm charged?
2-I'm emailed the bill each month as a PDF invoice - Are invoices valid proof or do I need a receipt? (I've heard invoices aren't valid records for expenses as technically invoices are issued BEFORE payment)

Thankyou for your help

1.  Yes.  
2. If you get an invoice and have some form of proof that you have paid, such as a bank statement, then there is no need for a receipt.  If you paid by cash, then getting a receipt would be advisable.
