Nobody switches early enough
Changing co-packers feels risky, so brands tolerate problems far longer than they should. Meanwhile the cost of staying compounds: missed reorders, inconsistent product, and retail buyers who quietly stop calling.
The signals
Quality drift. Your product tastes, pours, or looks different batch to batch and nobody can tell you why.
Capacity excuses. Your run keeps getting pushed because a larger client needs the line. This is the most common signal and the most predictive one.
Communication decay. You are chasing answers. When a plant stops volunteering information, it is usually because the information is bad.
Documentation gaps. You ask for COA data or lot traceability and it takes a week, or it arrives incomplete.
Pricing that never improves. Your volume tripled and your unit cost did not move. That is a relationship, not a partnership.
They cannot follow you up. They were right for 400 gallons. They are not built for 4,000.
The sequence that avoids a stockout
- Build inventory buffer first. Before any conversation, get enough finished goods to cover eight to twelve weeks.
- Secure your documentation. Your recipe, specs, COA history, and label compliance letter are yours. Collect them while the relationship is still cordial.
- Qualify the new plant with a real run. Test kitchen session, then a production run you approve before it ships. Never transition on a promise.
- Overlap deliberately. Run both for one cycle if your contract allows it. The redundancy is worth the cost.
- Then give notice, in writing, on the terms your agreement specifies.
What good looks like on the other side
You should know where your batch is without asking. You should receive QC results as a matter of course, not on request. You should be able to plan seasonal volume months ahead and have it honored. If a co-packer cannot describe how they deliver that, they cannot deliver it.
