# How pricing works > Term structure\, what changes at renewal\, and where the real number lives\. *Billing \& payments → Pricing \& plans* > **ONE AUTHORITATIVE PRICE** — Documentation never restates a price\. The live offer\, currency and term are published on [Pricing](/pricing) and confirmed again at checkout\. ## Term structure - Knarrion Pro\: Monthly\, Annual or Lifetime\. Every plan has every Knarrion Pro capability\; only the access term differs\. - Annual and Lifetime also include the complete course at no extra cost\. - Lifetime is offered for a limited time and can be withdrawn from Pricing\; existing lifetime Licenses are never affected\. - The course on its own is a one\-time purchase with lifetime access\. Knarrion Pro Custom is a one\-time purchase that includes Lifetime and the course\. - The term begins when the entitlement is issued\, not when payment is initiated\. ## What happens at the end of a term 1. **You are notified in the workspace** — Expiry state appears in [Account → My products](/account/products) before it takes effect\. 2. **Access stops\, data does not disappear** — An expired entitlement stops authorising the Expert\. Your orders\, tickets and account history remain\. 3. **Renewal issues a new term** — Renewal is an explicit purchase\. Nothing is charged silently\. ## Discounts Where a scheduled discount exists\, it is shown on the offer itself\: the regular price struck through\, the discounted price\, and the time left\. After the end date the regular price applies\. Documentation does not carry promotional codes\; if you have one\, see [Using a promotion code](/docs/commerce/promotion-codes)\.
