When to stop working with a vendor

Vendor loyalty is worth maintaining with good vendors, but knowing when a vendor relationship has run its course saves time, money, and frustration. Here are the signals I use.

Quality degradation over time

Vendor quality is not static. A vendor that produced excellent cards 18 months ago may have changed materials suppliers, equipment, or production staff. If your last two orders from a vendor show visible quality decline compared to earlier orders, that is a signal worth investigating. One worse card could be a random production variance. Two in a row suggests a systemic change.

Comparing notes with other recent buyers is the fastest way to assess whether a quality decline is real or isolated to your orders. If others report the same decline in recent forum posts, the vendor has genuinely changed. If others report normal quality and only your orders are affected, there may be an issue with your specific template or order parameters.

Support deterioration

Response time increasing beyond their historical baseline, vague answers replacing specific ones, guarantee terms being applied more narrowly than they were previously — these patterns indicate either staff changes, volume scaling issues, or a vendor in the process of exiting the market. None of these improve on their own.

Delivery pattern changes

A vendor whose average delivery time suddenly increases by a week or more, with no acknowledgment of the change, is experiencing shipping or logistics disruption they have not communicated. This may resolve, but it also may be the beginning of operational deterioration.

The switching cost

The cost of trying a new vendor is the price of one order and the time to verify quality. The cost of continuing with a declining vendor is cumulative bad orders plus the time to resolve them. Once you have identified two or three consecutive quality or service issues, the switching cost is clearly lower than the continuing cost. Move earlier than you think you need to.
