Quick answer. The cost of changing a supplier is usually recorded as the development and tooling fees, and that understates it. The items that dominate are the transition period, the double minimums, the working capital carried through it, and the ramp-up in quality that a new relationship goes through before it settles.
1. The visible costs
- Development. A new pattern, a new grade and its own sampling rounds.
- Tooling. Label plates, waistband tools, print plates or pack dies, and in most cases a second set.
- Sampling. The sample rounds themselves, including the trial premium on a small quantity.
- Re-verification. Testing and certification work confirmed against the new site and article.
2. The costs that are usually left out
- The transition period. Weeks in which both suppliers are being managed and neither is fully proven.
- Double minimums. Each site meets its own per style and colour, so the commitment rises rather than being divided.
- Working capital. Inventory carried to cover the overlap, which is cash held in stock rather than in the business.
- The quality ramp. A new relationship typically runs a higher defect rate for its first orders before the process settles.
- Management time. Which is the largest hidden item and does not appear as a line on any invoice.
3. The ramp-up, specifically
- It is normal rather than a warning. A new site is running a construction and a routine for the first time.
- It is not always visible in the order. Because the first order is often given extra attention precisely because it is the first.
- Where it does show. In the order after the honeymoon, when the routine is what governs rather than the attention.
- What to do about it. Inspect the first two orders more closely, and check the process records rather than only the goods.
4. The cost of staying, on the same basis
- Rework and rejects. The visible part of an unresolved quality problem.
- Returns and markdowns. Which arrive later and attach to the customer rather than to the supplier.
- Management time. The same load as the transition, applied every season rather than once.
- Opportunity. The styles not developed because the same problem absorbed the attention.
5. Making the comparison honest
- Put both on an annual basis. A one-time transition cost against a recurring cost is not comparable in a single season.
- Include the management load on both sides. Since it is the item most often omitted from both estimates.
- Separate one-time from recurring. The development and tooling belong to the first order; the rest recurs.
- Count the ramp. Which is a real cost of the change and belongs on the cost of leaving.
- Then decide. Against the number the problem actually costs per year, rather than against how the last incident felt.
6. Common errors
- Counting only the development and tooling. Which are the smallest of the items in most cases.
- Assuming the commitments are shared. Each site meets its own minimum, so the total commitment rises.
- Ignoring the transition period. Which is where the management load and the working capital sit.
- Expecting the new supplier to start at the old one’s quality level. Which ignores the ramp entirely.
- Comparing a one-time cost with a per-season cost. Which makes the change look cheaper than it is, or more expensive.
- Deciding on one incident. Since the figure the decision turns on is the annual cost of the problem.
7. How to compare leaving with staying
- Same period. Annual, so a one-time cost and a recurring cost are on the same footing.
- Same items. Development, tooling, sampling, re-verification, transition, double minimums, working capital, ramp and management time.
- Same management load. Counted on both sides, since it appears in both.
- Same quality assumption. With the ramp included in the change rather than assumed away.
- Then against the problem’s annual cost. Which is the figure the decision actually turns on.

Buyer checklist
- Record the visible costs: development, tooling, sampling and re-verification.
- Add the transition period in weeks and in management time.
- Plan for two minimums rather than a divided one.
- Cost the working capital carried through the overlap.
- Assume a ramp on quality rather than the incumbent's defect rate.
- Count the management load on both sides of the decision.
- Separate one-time costs from recurring ones.
- Put the comparison on an annual basis.
- Measure what the existing problem costs per year.
- Decide against that figure rather than against the last incident.
