Jewelry Subcontracting: Building a Reliable Manufacturer Network

Subcontracting is at the heart of the business model for many jewelry houses. Well managed, it offers flexibility, expertise, and competitiveness. Poorly managed, it generates delays, quality problems, and risky dependencies.

This guide will help you build and manage a reliable and sustainable manufacturer network.

Why Subcontract?

Strategic Motivations

Risks to Manage

Define Your Subcontracting Strategy

Make or Buy

The first question: what to do in-house, what to subcontract?

Decision criteria

Typical distribution example

Number of Partners

Single-sourcing One partner per specialty.

• Advantage: Strong relationship, negotiated terms
• Risk: Total dependence

Multi-sourcing Multiple partners per specialty.

• Advantage: Security, competition
• Risk: Dispersion, less commitment

Recommendation

• 2-3 qualified partners per critical specialty
• One main partner (60-70% of volume)
• One or two backup partners (30-40%)

Identify Potential Partners

Prospecting Sources

Pre-selection Criteria

Before going further, verify:

Elimination criteria

• Actual activity (visit if possible)
• Financial stability (check on company registries)
• Reputation (internet search, request references)

Relevance criteria

• Specialization (do they match your needs?)
• Location (compatible with your constraints?)
• Size (adapted to your volumes?)

Qualify Partners

Initial Evaluation

The workshop visit Nothing replaces an on-site visit to evaluate:

• Organization and cleanliness
• Equipment
• Teams and their motivation
• Actual capacity

Key questions

The Test Order

Before committing to volume, test with a real order:

What to observe

• Responsiveness upon receiving the order
• Questions asked (sign of seriousness)
• Respect of announced deadline
• Delivery quality
• Handling of any problems

Test evaluation grid

Partner Scoring

Establish a permanent scoring system:

Recommended indicators

Review frequency

• Continuous indicator monitoring
• Formal quarterly review
• Annual assessment with each partner

Contractualize the Relationship

Essential Clauses

The Confidentiality Clause

Critical in jewelry, it must cover:

• Designs and patterns
• Client information
• Prices and terms
• Processes and techniques

Recommended duration: 5 years after end of collaboration

Management of Entrusted Materials

If you supply the gold or stones:

To formalize

• Transfer procedure (witnessed weighing)
• Responsibility in case of loss
• Insurance
• Expected yield (acceptable loss rate)
• Waste recovery

Manage the Relationship Daily

Structured Communication

For each order

• Clear and complete technical specification
• Reception confirmation
• Progress updates if long production
• Delivery notification

Regularly

• Weekly check-in with main partners
• Monthly portfolio review
• Quality feedback

Handle Problems

Problems will happen. What matters: how you handle them.

Create a Balanced Relationship

A good partnership rests on balance:

What you bring

• Regular volume

• Clear specifications
• Mutual respect

• Priority when needed
• Continuous improvement

Loyalty Levers

Renew the Panel

Even with good partners, keep your eyes open:

• Occasional testing of new capabilities
• Terms benchmarking

This protects you and maintains healthy tension.

Handle Difficult Situations

The Failing Partner

Warning signs:

• Repeated delays
• Declining quality
• Degraded communication
• Financial problems (rumors, late supplier payments)

Action plan

1. Frank discussion about problems
2. Improvement plan with milestones
3. Progressive volume reduction
4. Activate backup partner
5. Disengage if no improvement

Excessive Dependence

If a partner represents more than 50% of your critical capacity:

Actions to take

• Actively qualify alternatives
• Progressively transfer volume
• Build safety stock
• Evaluate partial internalization

The Breakup

Sometimes, you must part ways. How to do it well:

• Respect the contract (notice)
• Clearly communicate the reasons
• Organize the transition properly
• Recover work-in-progress and materials
• Maintain a correct relationship (it's a small world)
