I understand that proper accounting means the provision of an invoice (I'm not registered for GST) for all sales. If I've already received a sales payment from a customer, do I instead need to provide a receipt? My accounting software doesn't generate receipts, only invoices. Is this the same thing? Do I use the invoice function even though it's post payment?
Sorry, thankyou, I realise this is kindergarten level accounting q'n yet it baffles me!!?
