How to Handle a Vendor Dispute

Resolve vendor disputes systematically using documentation, escalation protocols, and cost-benefit analysis to protect cash flow.

1. Document the dispute immediately. Create a dispute file with all relevant contracts, invoices, emails, delivery receipts, and photos. Include dates, dollar amounts, and specific performance failures. This documentation determines whether you win or lose if the dispute escalates to legal action or mediation.
2. Calculate your exposure and leverage. Total outstanding invoices, unpaid deposits, and potential replacement costs. Factor in business disruption costs—lost sales, delayed projects, or overtime to find alternatives. If your exposure exceeds 10% of monthly revenue, treat this as a priority dispute requiring immediate action.
3. Start with direct vendor contact. Email the vendor's account manager and copy their supervisor with a clear dispute summary, specific resolution timeline (typically 5-10 business days), and consequences for non-compliance. Keep the tone factual and reference contract terms. Save phone calls for urgent situations—emails create evidence.
4. Escalate through formal channels. If initial contact fails, escalate to vendor management, then invoke formal dispute resolution clauses in your contract. Send certified mail for disputes over $5,000. For smaller amounts, consider small claims court if the vendor won't engage within 30 days.
5. Protect your cash flow during resolution. Stop all payments on disputed invoices immediately. Place funds in escrow or separate account to show good faith while protecting working capital. If you rely on this vendor for operations, secure backup suppliers before the relationship deteriorates further.
6. Make the go-no-go decision. After 45-60 days, compare legal costs against potential recovery. Small claims court costs $50-300 but caps at $5,000-15,000 depending on state. Formal litigation starts at $5,000-10,000 minimum. Cut your losses if legal costs exceed 50% of the disputed amount.
