Royalty audit: documents to prepare
A royalty audit checks whether the sums a licensee reported match what the licence actually earned. Before you notify the other side, gather sales ledgers, licence text, prior statements and any correspondence about disputed figures. Missing paperwork is the most common reason an audit stalls at the first stage.
What a royalty audit checks
The audit compares three things: the licence terms, the reporting method the licensee used, and the underlying transaction records. A gap between reported royalties and actual sales does not by itself prove wrongdoing. It only tells you where to look next. The audit's purpose is to narrow that gap to a figure both sides can accept, or to a figure a decision-maker can rule on if they cannot.
Most audits start after a pattern emerges: flat royalties over several periods despite rising sales elsewhere in the market, or a licensee reporting figures that never change quarter to quarter. Neither pattern proves underreporting. Both justify a request to see the books.
Documents to prepare
Before you ask for access, assemble your own file first. An auditor working from an incomplete file wastes the first weeks reconstructing what the client already had.
| Document | Who usually holds it | Why it matters |
|---|---|---|
| Signed licence and any amendments | Licensor's own records | Defines the royalty base, rate and reporting period |
| Royalty statements received to date | Licensor | Shows what was reported and when |
| Correspondence about disputed periods | Both sides | Establishes when concerns were first raised |
| Sales or usage data from other channels | Licensor or market data providers | Gives a comparison point for the licensee's figures |
| Assignment or ownership records for the licensed right | Licensor | Confirms the licensor had standing to grant the licence |
Ownership records deserve particular care if the right passed through more than one hand before licensing. Our note on what changed in publication practice ownership of results covers how gaps in that chain surface during a later dispute, including an audit.
A licensee preparing for the other side's request should assemble a parallel file: unit sales by product line, returns and credits, any sublicensing income, and the calculation method used to arrive at each reported figure. Auditors ask for the calculation method more often than for the raw numbers themselves.
Who decides and how long it takes
Most royalty audits are resolved by negotiation between the parties, often through accountants acting under an audit clause in the licence. Where the clause names an independent auditor or accounting firm, that party's findings usually become binding within limits the licence sets out. Where no such clause exists, either side can still request access, but the other side can decline, which pushes the dispute toward mediation or a forum named in the licence.
Typical timing runs in stages, and each stage can stretch if records are incomplete.
| Stage | Typical duration |
|---|---|
| Request and access negotiation | 2–4 weeks |
| Document review and reconciliation | 4–8 weeks |
| Findings shared and response period | 2–3 weeks |
| Settlement or escalation | Variable |
If the numbers do not match: forks
- If the gap is small and the licensee agrees quickly, the parties usually settle by adjusting the next statement rather than reopening past periods.
- If the licensee disputes the auditor's method, the licence's own audit clause typically names how disagreements over methodology are resolved, and that clause governs rather than general negotiation.
- If the audit uncovers goods moving outside the licensed channel entirely, such as counterfeit stock rather than underreported genuine sales, the response shifts from royalty recovery to enforcement. Our note on customs application for action sets out what a decision-maker looks at once that shift happens.
Cost factors
What an audit costs in time and effort depends on a small number of variables rather than the size of the licence itself.
- How many reporting periods are in scope — three years of statements take longer to reconcile than one.
- Whether the licensee's accounting system separates licensed products from unlicensed lines, or requires manual splitting.
- Whether the audit clause names a fixed auditor or leaves selection open to negotiation.
- Whether the dispute stays commercial or moves toward a named forum.
We give a first response to any audit enquiry within minutes during working hours, and a fee estimate within one working day once we understand the scope.
How the file is structured
We keep three folders open from the first call: the licence and its amendments, the disputed statements with our own reconciliation notes, and correspondence with the other side. Nothing is filed under a client name a reader could recognise; our working files stay organised by matter reference, not by party.
What this page does not cover
This page sets out what to prepare and who typically decides. It does not cover what a licence should say about audit rights before a dispute exists — that belongs in drafting, not in procedure. It also does not cover disputes where the licensed right itself is contested rather than the reporting under it; that is a separate track entirely.
Verified
Checked against current practice on royalty reporting disputes and audit clauses in licensing agreements. We keep the audit report, the underlying extracts and our own copy of the file for the retention period set out in our retention: the report, the extracts and our copy step policy.

FAQ
How long does royalty audit take in practice?
Most audits run eight to twelve weeks from request to a settled figure, longer if the licensee's records need reconstruction before review can start.
Which documents are needed to start?
The signed licence, all royalty statements received so far, and any correspondence about disputed periods. Everything else follows once the scope is agreed.
What happens if the other side does not respond?
Silence does not stop the clock the licence set for reporting or audit rights. It does narrow the options to the forum the licence names, or to mediation if none is named.

If sales data outside the licensed channel is encoded on a distributed ledger, the audit trail looks different again. See when royalties encoded on-chain are ignored in practice for that scenario.
If the licensed right sits inside a patent family with an opt-out window closing, timing pressure changes the whole calculation. See when the opt-out window is closing on a family.
If the dispute has already moved to a trade fair and seizure is threatened, the audit becomes secondary to an immediate response. See when a trade fair seizure is threatened in practice.
