Licensing Benefits

Infix licensing is per user not per machine, so if you upgrade your computer you can transfer it to the new machine without further cost. Also, if you have a work and home computer you can install Infix on both with a single license as long as Infix is not run concurrently on both machines. You may also switch between Mac & PC versions of Infix using the same license.

When you purchase a license for Infix your license for that version will never run out. You will get free upgrades for all minor releases for that version (e.g. v6.16 -> v6.17). We typically release a minor upgrade every 4 to 5 weeks.

We release a major version of the software (e.g. v6 -> v7) roughly every 2 - 2.5 years. Purchases up to 3 months prior to a major version get a free upgrade to the newer version. Outside of that 3-month window, anyone can upgrade an old version to the latest Professional version with around 60% discount.

Finally, we keep a record of all purchases from our site. Should you ever need your activation key to re-install Infix, send us some details of the purchase so that we can locate it (e.g. email or physical address) and we will send you your keycode. You can also download copies of all previous versions of the software from our support page.

Enterprise Licenses

For less than the cost of 30 licenses, an Enterprise license provides up to a maximum of 1,000 Infix Pro licenses for your company or organisation. The license grants umbrella cover to all employees of your organisation, including those in other territories or international subsidiaries. Affiliates, sub-contractors, freelancers and other entities legally distinct from the ‘company’ are not covered.

Email support plus all software updates (minor and major) for 12 months from the date of purchase are included. Annual support beyond that time can be purchased for $995.

Infix is compatible with Citrix desktop virtualisation solutions. It can also be installed silently making remote deployment very straight forward.

If you have any questions about licensing, please get in touch.

Free Licenses

What is ‘Pay & Save‘?

Ideal for users who only want to edit a few PDFs; one purchase of $30 made from within Infix gives three ’saves’ – each save will remove all the watermarks from an edited PDF. Save with a watermark whilst you are still working on a PDF, then only use a Pay & Save when you have finished and are happy with all your edits.

Watch "Pay & Save – The Movie" to see the processing in action.

If you use up all your Pay & Saves, more can be purchased from within the demo version of Infix or Infix Pro. When you save your edited PDF, click on the "Pay & Save" button and follow the instructions.
