Sub-Affiliate vs Multi-Tier Commission

Sub-affiliate programs and multi-tier commission structures both reward affiliates for recruiting other affiliates, but they differ in depth and complexity. A sub-affiliate model is a simple two-level structure: the recruiting affiliate earns an override commission — typically 5–15% — on the earnings of affiliates they directly recruit. Multi-tier commission extends this concept across multiple levels, with each tier earning a decreasing percentage from the tiers below.

The practical difference becomes clear in network architecture. In a sub-affiliate model, Affiliate A recruits Affiliate B and earns a percentage of B's commissions. If B recruits Affiliate C, A receives nothing from C's activity. In a multi-tier model, A earns from B (Tier 1), B earns from C (Tier 1), and A also earns a smaller percentage from C (Tier 2). This cascading structure incentivizes deeper network building.

Multi-tier structures are most common in Forex Introducing Broker programs, where the Master IB → Sub-IB hierarchy naturally creates multiple referral layers. The IB agreement typically defines commission rates at each tier level, with diminishing percentages as the tiers deepen. This mirrors how real brokerage partner networks operate.

For operators, multi-tier programs add significant complexity to payout calculations and reporting. Every conversion must be traced back through the full referral chain, and commissions must be calculated and distributed to multiple parties. This requires robust tracking infrastructure and clear commission split logic to ensure accuracy and transparency across all levels.
