Commission shaving refers to a suspected or actual reduction in the number of credited conversions or the commission paid to an affiliate by an advertiser or affiliate program. The term is generally used when an affiliate believes that their payout has been reduced without sufficient justification based on the traffic and conversion data available to them.

It is important to distinguish commission shaving from a legitimate conversion rejection. A conversion may be rejected because of fraud, duplicate accounts, GEO restrictions, prohibited traffic sources or other offer conditions. A discrepancy between an affiliate's tracking data and an advertiser's report does not, by itself, prove commission shaving.

What Does Commission Shaving Look Like?

Commission shaving is rarely identified through a single metric. Suspicion usually arises when several data points consistently fail to match:

  • Conversions are missing from the affiliate report. An affiliate's own tracking system may record events that do not appear in the advertiser's statistics. This can also happen because of technical tracking problems, so a single discrepancy is not enough to establish shaving.
  • Unexpectedly low approval rates. A large share of tracked conversions is rejected without a sufficiently detailed explanation.
  • Unexpected payout adjustments. The amount credited to the affiliate is lower than the agreed terms or changes without a clear explanation.
  • Revenue Share discrepancies. Under RevShare, disputes may arise because of differences in revenue calculations, deductions or the methodology used to determine NGR. The calculation method should therefore be agreed in advance.
  • Terms change after traffic has been launched. If rates, caps or conversion qualification rules change after a campaign starts, affiliates should verify whether the new terms apply to previously generated traffic.

What Causes Commission Shaving?

Not every discrepancy is intentional manipulation. Possible causes include:

  • Unethical actions by an advertiser or affiliate program. In this scenario, conversion statistics or payouts may be deliberately adjusted to reduce the amount paid to the affiliate.
  • Multiple intermediaries. When several parties sit between the affiliate and the final advertiser, discrepancies may occur at different stages of data processing.
  • Technical issues. Problems with a postback URL, parameter transmission or attribution can cause conversions to be lost or recorded incorrectly.
  • Unclear offer terms. If the program does not clearly define what qualifies as a valid conversion or which deductions are allowed, the parties may interpret campaign results differently.

For this reason, it is more accurate to describe an unexplained discrepancy or suspected commission shaving until the data and the affiliate program's terms have been reviewed.

Commission Shaving vs. Legitimate Rejections

To avoid making an unsupported accusation while still identifying systematic payout issues, affiliates should check several factors:

  • The rejection reason is specific. A legitimate rejection may be related to fraud, duplicate accounts, GEO restrictions, prohibited traffic sources or other offer rules. A clearly documented reason is easier to verify.
  • Independent tracking data is available. A tracker can provide an independent source for comparing clicks, events and conversions with the affiliate program's reporting.
  • The discrepancy is recurring. A one-off tracking issue does not establish shaving. A persistent difference between data sources deserves further investigation.
  • The traffic complies with the offer terms. If the traffic violates the program's rules, a rejection may be fully justified. For example, motivated traffic may be rejected when the offer explicitly prohibits it.

How Can Affiliates Protect Themselves From Commission Shaving?

  • Keep independent records. Your own tracking data provides a basis for comparing clicks, events and conversions with the affiliate program's statistics.
  • Use SubIDs for traffic-level analysis. SubIDs make it easier to identify which traffic segments are associated with a discrepancy.
  • Reconcile data regularly. Frequent checks make it easier to identify problems before discrepancies accumulate into significant amounts.
  • Start with a test volume. Before scaling, verify how the program records conversions and calculates payouts.
  • Review the program terms in advance. Understand approval rules, caps, hold periods, payment terms and rejection conditions before sending significant traffic.
  • Work with established affiliate programs. Transparency and reputation matter alongside the headline payout.
  • Document commercial terms. Rates, caps, payment schedules and conversion qualification rules should be confirmed in writing.
  • Do not confuse shaving with payment delays. A hold period or temporary payment issue does not, by itself, indicate that commissions are being reduced.

What Should You Do If You Suspect Commission Shaving?

  1. Collect the data. Export clicks, conversions, SubIDs, timestamps and postback information from your tracking system.
  2. Compare it with the partner's report. Identify the specific events or conversions that do not match.
  3. Quantify the discrepancy. Record the difference in conversions and the estimated financial impact.
  4. Request an explanation in writing. Ask specific questions about rejected conversions, rejection reasons and the rules applied.
  5. Check the technical setup. Verify that postbacks and parameters are being transmitted correctly and that tracking settings have not changed.
  6. Look for a pattern. A one-off, explainable discrepancy should not automatically be classified as shaving. A recurring unexplained discrepancy may justify reducing traffic volume or reconsidering the partnership.

Commission Shaving and Other Affiliate Metrics

Commission shaving is usually identified by comparing several metrics rather than looking for a single warning sign:

  • a lower approval rate reduces the number of paid conversions and can increase the effective cost of customer acquisition;
  • discrepancies in RevShare affect the affiliate's revenue and the resulting LTV calculation;
  • differences in GGR or NGR calculations can directly affect RevShare payouts;
  • unexplained deductions should be reviewed in detail to distinguish genuine chargebacks from other adjustments.

These metrics describe different aspects of affiliate economics rather than a single linear funnel.

Common Affiliate Mistakes

  • Working without independent tracking. If all data comes from the affiliate program, there is no independent basis for reconciliation.
  • Relying on verbal agreements. Rates and commercial terms should be documented.
  • Scaling before verifying payouts. Test the offer at a limited volume before committing a larger budget.
  • Calling every rejection commission shaving. Some rejected conversions are legitimate and follow the offer's rules.
  • Ignoring small recurring discrepancies. Even a relatively small systematic difference can become significant at scale.
