Why One Supplier Is a Risk, and What Dual Sourcing Actually Costs
By The Velocity Wear Team
Concentrating volume with one supplier gets you better pricing, simpler communication and consistent product. It also means every disruption to that supplier is a disruption to your entire business, with no alternative available at the speed you would need one.
What actually goes wrong
- **Capacity.** Your supplier takes a large customer and your orders move down the queue. This is the most common and least dramatic failure.
- **Quality drift.** A change of fabric source or a staffing change, and the garment is subtly different. Nothing announced, and you find out on arrival.
- **Trade measures** affecting a country of origin, which arrive with little notice.
- **Logistics.** Port congestion, route closures, freight capacity.
- **Business failure.** Rare, immediate, and total.
What a second supplier actually costs
- 1**Worse pricing at both.** Split volume means both suppliers quote at lower tiers. With tiers running to 40% off at the deepest volumes, this is a real number rather than a rounding error.
- 2**Consistency risk.** Two factories producing the same garment will produce slightly different garments. Fit, shade and hand feel will not match exactly, and customers reordering will notice.
- 3**Duplicated setup.** Two sets of samples, two artwork approvals, two sets of patterns, two relationships to maintain.
- 4**Management time,** which is the cost nobody budgets.
The version that works for smaller buyers
Full dual sourcing — splitting every style across two factories — rarely makes sense below serious volume. Two lighter approaches capture most of the benefit.
The first is splitting by product rather than by style: core staples with one supplier, seasonal or reactive product with another. Each still gets meaningful volume, you have a live relationship with two, and neither is a cold start if you need to move.
The second is a qualified alternative rather than an active one. Sample with a second supplier, get their pricing, approve their quality, and place a small order once a year to keep the relationship alive. You are not splitting volume; you are buying an option. Ordering a small run at a low minimum is exactly what makes this affordable — it is a test rather than a commitment.
Diversify origin, not just supplier
Two suppliers in the same country, buying fabric from the same mills, does not protect against the risks that actually materialise at country level — trade measures, port disruption, regional events. If resilience is the aim, the second source should differ in origin, not merely in company name.
Deciding whether you need it
Ask what happens if your supplier cannot deliver for three months. If the answer is that you lose a season and recover, single sourcing is a reasonable bet. If the answer is that you cannot fulfil contracts, lose accounts, or shut a programme, buy the option. The premium is much smaller than the exposure.
