The ability to add clickable, customizable links in generated invoices and reports has been requested often. This will be available in Studiometry 9.0 via a new Template Item type (Web Link). Web links are areas that can include an image or text, and link to a customizable URL. The URL in Studiometry can even include variables to allow for dynamic links, and the ability to make payment links directing to Paypal or other services.
The links will only be clickable in PDF output, which will also be available in Studiometry 9.0 for Mac & Windows machines.
