Key Takeaway: Single-source risk is invisible until the day it isn't. A delay, a price shock, or a supplier going out of business, with no backup plan already in place.

Identifying Your Risk
For every SKU, ask: if this supplier had a serious delay tomorrow, how much would it actually hurt? Cross-reference with an ABC analysis. Single-source risk on an A-tier SKU deserves real attention; on a C-tier SKU, it usually doesn't.
Reducing Risk Without Over-Engineering It
- Qualify a backup supplier for your highest-risk, highest-value SKUs. Even if you rarely use them, having them vetted saves critical time during a real disruption
- Avoid concentrating too much total spend with a single supplier if a realistic alternative exists
- Build slightly more safety stock for SKUs where supplier risk is genuinely elevated
A Real Example
An electronics retailer discovered a meaningful quality gap between two suppliers only after formally comparing their return rates side by side. See the full case study for how that comparison paid off in leverage, not just risk reduction.

Common Mistakes
FAQ
What's the most common supplier risk for small businesses?

Identifying at least a backup supplier for critical items, even if not used regularly, so there's a known fallback.
Should supplier financial health be a concern?
For critical, ongoing relationships, yes. A supplier in financial trouble can disappear with little warning.
How does supplier scoring relate to risk management?
A declining performance trend is often the earliest visible warning sign of a supplier heading toward bigger problems.
