# The billing manual

<!-- module: s21-billing · deck: What an organisation pays for its products, and how it pays at id. -->

**Table of contents · 8 November 2026 · plan TB, built (TB1 to TB6). Plans, paying, renewals and lapses, invoices, and a product getting plans.**

Billing is where an organisation's owners and billing people see what it pays and what's due, choose a plan for each product it runs, and pay for it. It lives at `id`, under Billing. The payment
itself is taken on Paystack's own page: nothing of Paystack's runs on `id`, and Atrium never sees a card number.

The one sentence to carry through it: **a payment counts once, whichever way the news of it arrives.**

**Who meets what**

| Owner | Holds the organisation | Sees the plans, pays, moves up or down |
| Billing | Pays the organisation's bills, and nothing else (CL-16) | The same, and sees nothing else of the organisation |

Admins and members don't see Billing.
