Did you know, if you are GST registered and you supply goods/services to someone who is also GST registered you have to provide an invoice within 28 days of a request by the purchaser; otherwise it is an offence which can attract penalties.

 A good idea is to set up a template with all information required, regardless of whether your invoices are for $30 or $3000 and use that for everything – that way you will know that you are always meeting the requirements of a tax invoice.
