The term postage means the amount you pay to send an item by post. You can show your postage is paid in the following ways:
You can buy stamps in various denominations to cover the postage rate of the mail you're sending.
Self-adhesive stamps are the easiest to use, and you can buy them in bulk from all post offices and business centres.
With prepaid envelopes or satchels, you simply address your item and drop it in a street posting box - there's no need to worry about buying stamps separately, as the price includes the postage as well as the cost of the envelope or satchel. You get a discount when you buy prepaid envelopes or satchels in bulk.
A postage paid imprint can be printed directly onto the upper right hand corner of your items (where a stamp would normally be) to show that the postage has been paid. It features the words "POSTAGE PAID AUSTRALIA" and is useful if you want to pay using an Australia Post Business Credit Account, or make large volume lodgements.
Please note: Articles bearing a 'Postage Paid Australia' imprint must be lodged at a Post Office.
Many small to medium businesses use postage meters as a convenient way to pay for postage. A meter prints an 'indicia' (markings that show postage has been paid by the sender) on your mail, showing the value of the postage.
So there's no need to stick on a stamp or preprint the words "Postage Paid Australia".
Once your postage meter is set up, you can download postage at any time. You also get a 2.5% rebate every time you reset your meter.
