Product diversion—when inventory leaks from your authorized partners into unauthorized channels—is one of the most costly risks for brands selling wholesale. Auditing your wholesale accounts regularly is critical for catching leaks, protecting pricing, and keeping control over your Amazon and retail channels.
Here’s how to audit wholesale accounts effectively, and what to look for to spot and stop diversion.

1. Start with Rigorous Sales Vetting and Onboarding
Before you even begin an audit, make sure you’re onboarding wholesale partners carefully:
- Conduct background checks and reference calls.
- Watch for unusual activity during onboarding (like extra large or erratic orders).
- Require written agreement to your MAP, marketplace, and diversion policies.
- Align incentives—ensure your sales team isn’t pushing orders to questionable buyers just to hit quotas.
A solid onboarding process helps set expectations and builds a foundation for future audits. It also reduces the risks outlined in what causes product diversion.
2. Screen for Known Bad Actors with a Brand Protection Firm
- Consider hiring a brand protection firm to screen your wholesale customers against industry databases of known grey market, unauthorized, or high-risk sellers.
- Regularly compare your active sales list to these watchlists as part of your audit process.
- Proactively removing or monitoring these accounts reduces your exposure to diversion and repeat violators.
3. Review Sales and Purchase Order Data
- Analyze order volume and frequency: Look for spikes, large or inconsistent POs, or growth that isn’t explained by market trends.
- Cross-reference against end markets: Are customers suddenly buying much more than their territory or channel justifies?
- Watch for unusual payment patterns or order methods.
Understanding how wholesalers operate in your supply chain is critical—see Distributor vs. Wholesaler vs. Retailer and Wholesale vs Direct-to-Consumer.
4. Implement Serialization, Lot Codes, or Batch Tracking
- Use unique identifiers on products or cases. This allows you to trace back any product found on unauthorized channels to the original wholesale customer.
- Audit serials or lot codes during reviews and compare with sales records.
5. Conduct Surprise Audits and Inventory Checks
- Schedule unannounced inventory audits at your wholesale partner’s facility.
- Compare reported inventory with physical stock and recent shipments.
- Investigate any missing, unaccounted-for, or excess product.
6. Test Buys from Unauthorized Channels
- Purchase your products from suspected grey market or unauthorized Amazon sellers.
- Record lot/serial numbers and match to your shipping records to identify the original leak.
This is one of the most effective ways to trace diversion back to source—see how to track product diversion and Amazon test buys.
7. Monitor MAP Compliance and Amazon Listings
- Use MAP monitoring and marketplace surveillance tools to catch violations instantly.
- Document any price drops, unauthorized listings, or account names matching your partners.
If needed, escalate with MAP enforcement or take steps to remove unauthorized sellers on Amazon.
8. Audit Returns, Overstock, and Liquidations
- Review any inventory sold as overstock, returns, or closeouts.
- Check whether wholesale accounts are offloading excess to liquidators who feed the grey market.
9. Interview and Communicate with Your Partners
- Speak directly with wholesale customers during the audit process.
- Clarify expectations and reinforce your policies on MAP, marketplaces, and diversion.
- Discuss any irregularities openly, and provide a chance for explanation.
10. Take Action on Findings
- If you identify a leak or violation, act quickly:
- Issue formal warnings or cease & desist letters
- Apply contractual penalties
- Suspend or terminate supply if necessary
In severe cases, brands may also need to address upstream issues, such as stopping distributors from selling on Amazon or investigating whether wholesalers are selling on Amazon.
