Multi-Tier IB Reporting

8 min read

A Forex broker in Southeast Asia has a master IB in Jakarta who manages 40 sub-IBs across Indonesia, Malaysia, and Thailand. The master IB earns an override on all sub-IB volume. Each sub-IB has their own traders. The broker needs to track, report, and pay commissions across three layers -- and every party needs to see exactly what they earned and why. Multi-tier IB reporting is where Forex tracking systems face their hardest test.

How Multi-Tier IB Structures Work

In a multi-tier IB structure, a master IB recruits sub-IBs who in turn refer traders. The master IB earns a direct commission on traders they personally refer, plus an override commission on the volume generated by their sub-IBs. The override is typically lower -- if a sub-IB earns $6 per lot, the master IB might earn a $1.50 override on those same lots. Some brokers allow three tiers: master IB, sub-IB, and sub-sub-IB, each with decreasing override percentages.

Tier	Role	Commission Source	Typical Rate
Tier 1 (Master IB)	Recruits and manages sub-IBs	Override on sub-IB volume + direct referrals	$1--$3 override per lot + $6--$10 on direct
Tier 2 (Sub-IB)	Refers traders directly	Direct commission on referred trader volume	$5--$8 per lot
Tier 3 (Sub-sub-IB)	Refers traders under a sub-IB	Direct commission on own referrals	$4--$6 per lot

Cascading Attribution Challenges

The core challenge in multi-tier reporting is cascading attribution: when a trader closes a 2-lot position on EUR/USD, the system must calculate the sub-IB commission, then cascade upward to calculate the master IB override, applying the correct rate at each level. If the sub-IB is on a tiered deal where their rate changes at 500 lots per month, the cascade must use the current tier rate, not the base rate.

Timing adds complexity. If the sub-IB crosses a tier threshold mid-month, do the improved rates apply retroactively to all lots that month or only to lots traded after the threshold? If the master IB override is calculated as a percentage of the sub-IB commission (not a fixed amount), the override changes whenever the sub-IB rate changes. These cascading dependencies are where most spreadsheet-based systems fail.

Never calculate multi-tier commissions in sequence without locking the tier snapshot first. If the system calculates sub-IB A's commission, which pushes the master IB over a volume threshold, which changes the master override rate, which retroactively affects sub-IB B's already-calculated commission -- you have a circular dependency. Lock tier levels at the start of each calculation cycle.

Transparency for Every Tier

Each participant in a multi-tier structure needs reporting that matches their role. The master IB needs to see their own direct referral performance, each sub-IB's volume and commission, and their total override earnings. The sub-IB needs to see their own traders, their own commissions, and their tier status -- but not the master IB's override or other sub-IBs' data.

Master IB view: aggregate sub-IB performance, override earnings breakdown, network growth trends, and sub-IB tier distribution
Sub-IB view: personal trader metrics, commission accruals, tier progress, and payout schedule -- no visibility into peer sub-IBs or master IB overrides
Broker admin view: full network tree, total commission liability by tier, override cost analysis, and margin impact per master IB network
Reconciliation view: side-by-side comparison of calculated commissions vs. actual payouts, flagging any discrepancies for review before payment

Reconciliation Before Payout

Multi-tier payouts should never go out without a reconciliation step. The broker finance team needs a report that shows: total commission calculated per tier, total override costs, the commission-to-revenue ratio for each master IB network, and any flagged anomalies. Common anomalies include sudden volume spikes from a single sub-IB (possible wash trading), commission amounts exceeding revenue from the referred traders, or inactive sub-IBs suddenly generating volume.

The reconciliation report should compare the current period against the previous three periods for each master IB network. A 40% jump in override costs without a corresponding increase in net revenue is a signal that deserves investigation before payment is released.

Build a payout approval workflow with two steps: automated pre-check (flags anomalies, validates calculations) and manual review (finance team approves flagged items). This prevents both overpayments from system errors and delayed payouts from unnecessary manual review of clean calculations.

Key Takeaways

Multi-tier IB structures require cascading commission calculations that apply correct rates at each level and handle tier changes mid-period
Lock tier snapshots at the start of each calculation cycle to prevent circular dependencies in cascading overrides
Each tier needs role-appropriate reporting -- master IBs see network performance, sub-IBs see only their own data, brokers see the full picture
Run reconciliation before every multi-tier payout to catch anomalies like commission-to-revenue ratio spikes or sudden volume surges
Automated pre-checks combined with manual review for flagged items balance payout speed with financial controls

Master IB

A Master IB is an introducing broker who recruits and manages a network of Sub-IBs beneath them. The Master IB earns override commissions on the trading volume generated by their downstream partners in addition to commissions on their own direct referrals.
