A plan isn't edited "in place" once created: to change its price, features, limits or allowances, you create a **new version**. This prevents a price change from silently affecting subscribers who are already on a previous version. **Requirements:** Owner role — same permission as creating a plan (previous section). 1. On the plan's row, tap **New version**. 2. The form opens **preloaded** with every value from the previous version — name, description, price, feature codes, limits and allowances — except the **Slug**, which shows locked ("Inherited from the previous version, not editable"): every version of a plan shares the same slug. 3. Change whatever you need — for example, the **Monthly price**. 4. Tap **Create version**. **Result:** the Plans table shows **both versions as independent rows** of the same plan (same name and slug, different **Version** — v1, v2…), **both active at once** until you archive one of them: the old version keeps existing for whoever already had it, while the new one becomes available for new sign-ups.
