Definition
Self-billing is an arrangement in which the customer, not the supplier, produces the invoice for a transaction and sends it to the supplier for payment. In affiliate marketing this is the norm: the operator or network calculates what each affiliate earned for the period from its own tracking data and issues a self-billed invoice or statement on the affiliate's behalf, rather than waiting for hundreds of affiliates to each submit their own.
Tax rules in many jurisdictions permit self-billing only under a written agreement between the parties that meets specific conditions.
The practice exists because the paying party holds the authoritative data — clicks, registrations, deposits, revenue, deductions — and calculating from that data is faster and more consistent than reconciling incoming invoices. The trade-off is that the affiliate is accepting the operator's figures, so the value of self-billing depends on the statement being detailed and on the affiliate being able to check it against its own tracker.
In context
For iGaming affiliates, self-billing means the monthly statement from each programme is the primary financial record, and the discipline is to reconcile it rather than accept it blindly. The affiliate compares the operator's reported clicks, registrations, FTDs and qualifying events against its own tracker for the same period, checks that the deal terms (CPA amounts, revenue-share percentage, hybrid split, any caps) were applied correctly, and scrutinises deductions — bonus costs, chargebacks, fees, negative carryover, adjustments for players deemed fraudulent or self-excluded.
Small consistent discrepancies compound across many programmes.
Disputes usually come down to the detail behind the self-billed figure: which conversions were counted, which were rejected and why, how a revenue-share deduction was calculated, whether a clawback was justified. A programme that provides a granular, exportable statement — event-level where possible — makes reconciliation feasible and disputes resolvable; one that provides only a single net number invites mistrust.
For the affiliate, keeping independent tracking, reconciling every statement on a schedule, and raising discrepancies promptly with evidence is the practical protection, since under self-billing the affiliate is not the one drafting the invoice and has to verify rather than assert the amount.
Worked example
An affiliate reconciles a network's self-billed statement and finds 40 FTDs it tracked are missing from the operator's count. It raises the gap with event-level tracker logs; the operator identifies a postback outage, replays the events, and issues a corrected statement.
Because the affiliate reconciles every month, the error is caught and fixed rather than absorbed.
