Hi Kenneth,
Our intention is to give everyone who comes to the site a free invoice, or a free printable invoice, as it says on our website and in Google (i. E., Edit, print or download this professional invoice for free). For most of the people visiting us, this covers their needs as they only need one or two invoices. However, if you need invoices on a regular basis we can't afford to provide the service for free forever. We are a small business, and developing, maintaining and supporting it costs money and resources. We have, therefore, created a 21-day free trial where you can create as many invoices as you want. This allows you to familiarize yourself with our service to see if it is suitable for your invoicing needs. After the trial is over, you will still be able to view, print or download all existing invoices. However, if you try to create a new invoice after this date, you'll see an end-of-trial notice above the invoice. The notice will also contain information about how to upgrade / continue with our service if that is of interest. At no point will you be billed / charged; you have to actively sign up for a paid plan if that is what you choose to do. If you have any follow-up questions or concerns, please contact support@aynax.com and we'll do our best to help. Kind Regards, Lars. Marketing Dept.
