What the licence covers

Per user, one-time

A Single licence is for one named user on the machines they personally use. Site licences count users within your organisation, not installations. You pay once; there is no subscription and no annual renewal fee.

Minor updates free

A 2.x licence covers every 2.x release at no extra cost. A future major version (3.0) is a separate purchase, typically offered to existing customers at a discount.

30-day money-back

Not the right fit after all? Ask for a full refund within 30 days of purchase — no questionnaire. See the Refund Policy.

Offline licensing

A signed licence file — no online activation, no account, no phone-home. Deployable company-wide through the MSI’s LICENSE= property.

Invoices with VAT

Buying for a company? Paddle issues a proper invoice at checkout, with your VAT ID and the applicable tax shown — nothing to request afterwards.
