Guys collecting money and chasing overdue invoices successfully is about 80% preparation and 20% execution. Making the actual request for payment is such a small part of the overall process. Doing your homework, researching your customer’s proper name, confirming their correct entity, name, street address, email address are almost as important and you should be doing this every single time without fail. Being thorough and having an extremely high attention to detail are so vital- if your customer is called Andy, then make the invoice out to “Andrew”. If you are unsure of their actual business name, use the free ABR lookup tool. On ASIC if their company is a Pty Ltd, actually use the full stop after Pty Ltd if they do. Make your invoice out to the exact same entity as it is on ASIC, including all the tiny nuances you would ordinarily assume aren’t important. I can guarantee your customer will notice the level of detail and will assume you are particular, careful, diligent and methodical- all qualities that will reflect on you and your work, and make the customer feel more comfortable paying you. I cannot stress how important this is and it may be the difference between you getting paid and not.
