Every piece of paper filed should talk to you
On all supplier invoices clearly record how and when an invoice is paid. You’d be surprised how often I find this vital information missing.
- Date paid
- Credit card or bank account used
- Cheque number if applicable
A quick visual glance will then tell you if an invoice still requires attention or where to look to find additional third-party evidence of the payment i.e. a bank or credit card statement.
The same should be done with customer invoices. Any queries or disputes are then quickly resolved.
