You can use Link4 for free, yes for free! Our Link50 plan is for free if you send less than 50 invoices per month.
If you are enjoying using Link4 and are seeing the benefits of eInvoicing, you can then upgrade your plan based on the amount of invoices you send.
The average cost of a Link4 plan less than the cost of an Australian postage stamp to send an invoice by mail.
