# Multi-tier & network commissions

> Pay partners on the sales of the partners they recruit, with a pool that can never mathematically overpay.

Multi-tier commissions let a partner earn not just on their own sales, but on the sales of
partners they bring in — a network that grows itself. TrackRev's model is designed so the **total
paid across an entire chain can never exceed the pool you set**, no matter how deep it goes.

## Turn it on

In the programme form (cash programmes only), open the **Multi-tier commissions** section and
enable it. Configure:

| Setting                       | Meaning                                                    | Default |
| ----------------------------- | ---------------------------------------------------------- | ------- |
| **Total pool**                | Max share of a sale paid across the entire chain, combined | 30%     |
| **Tier 1 rate**               | What the partner who made the sale earns                   | 10%     |
| **Min level payout**          | Stop paying up the chain once a level rounds below this    | \$1     |
| **Max levels**                | Safety cap on chain depth (1–50)                           | 8       |
| **Auto-enrol every customer** | Give each buyer their own referral link automatically      | On      |

A live **decay preview** shows the rate and payout at each level for a sample sale.

## How the maths works

Each level up the chain earns a decaying share:

* `decay ratio = 1 − (tier 1 rate ÷ total pool)`
* `rate at level N = tier 1 rate × decay ratio^(N−1)`

Because the infinite series converges exactly to the **total pool**, the chain can never pay out
more than the pool you set — the seller earns the most, and each level above earns geometrically
less until the dollar floor or level cap stops it.

<Info>
  With the defaults (10% tier-1, 30% pool), the direct seller earns 10%, their recruiter \~6.7%,
  the next level \~4.4%, and so on — summing toward 30% but never exceeding it.

## Auto-enrolling customers

With **Auto-enrol every customer** on, every buyer silently gets their own referral link placed
under the partner who sold to them. This turns happy customers into a self-expanding referral
network without them having to opt in — the essence of product-led referrals.

## The Network dashboard

Open **Affiliate program → Network** to see the tree in action:

* Stat cards: **Affiliates in tree**, **Active (have sold)**, **Deepest chain**, **Auto-enrolled
  customers**.
* A revenue-mix card, a list of network sales, and the indented **Referral tree**.

Network commissions carry the actual seller as their source, and the first time a partner earns
passively from their downline, a `partner.first_commission` webhook fires (see
[Webhooks](/developers/webhooks)).

<Note>
  Banned or rejected partners in the middle of a chain drop out of the payout but don't sever the
  chain — the levels above them still earn.
