Leak 17 · Suppliers & Procurement - Poor supplier consolidation
Six suppliers for one category, none reaching a volume tier, each shipping under the freight minimum. The spread was never decided. It accumulated.
Diagnostic note. Symptoms, required records, an initial check, and possible fixes. This shorter note does not include a full worked example.
What is it?
Supplier spread grows through acquisitions, salesperson preferences, one-off sourcing, and inertia. It costs money through missed volume tiers and rebates, inbound freight on small POs, more receiving and AP work, and weaker negotiating position. It also has real benefits in resilience and customer preference, which is why it should be a decision rather than an accident.

Ask yourself
For your top product categories, how many suppliers do you buy from, and does the spread cost you tiers, freight minimums, or rebates?
Yes, partially, no, or don’t know. “Don’t know” is the most useful answer, because it points at the test below.
What does it look like?
Warning signs. None of these proves the leak exists. They tell you where to look.
- Categories with many suppliers and no primary.
- Many small POs under supplier freight minimums.
- Volume spread so that no supplier reaches a meaningful tier.
What data do I need?
The minimum viable set. Most of it is already in your ERP.
| Field |
|---|
| Purchases by supplier and category for 12 months |
| Supplier tier and freight-minimum terms |
| PO count and average PO value by supplier |
The initial check
Start with a small sample. Gathering the exports, agreements, or observations is separate from running the check; agree that work with the person who owns the records.
- 1For your top three categories, list every supplier and annual purchases from each.
- 2Note the tier and freight-minimum terms of the two largest.
- 3Estimate what the category would earn in tiers and freight if 80% of volume went to those two.
Consolidation value = (tier saving + rebate uplift + inbound freight saving) − loss of any supplier-specific advantage
Then ask one question: Is the spread in each category a decision anyone made?
How much could it be costing us?
A conservative range, not a headline. The goal is a number management can trust enough to investigate.
Σ over categories of consolidation value × share of volume that can realistically move without customer impact
Common root causes
Fixes fall into three layers. Not every problem needs software, and almost none needs AI first.
- Process
- No category sourcing strategy or periodic supplier review.
- Data
- Purchases are not analyzed by category, only by supplier.
- Technology
- Buyers select suppliers item by item with no view of category volume.
What should we do?
Start with the simplest intervention that could solve it. Move down the list only if the one above is not enough.
Level 1
Visibility
A category-by-supplier purchase matrix, annually.
Level 2
Strategy
A primary and secondary supplier per category, with the reasons written down.
Level 3
Workflow
Replenishment defaults to the primary supplier and flags off-strategy buying.
Where AI helps
- Categorizing items and cross-referencing equivalent products across suppliers when the item master is inconsistent.
Where AI probably doesn’t
This is a sourcing decision. The purchase matrix and a meeting come first.
Before you call it a leak
- Customers often specify brands. Consolidation is limited by what they will accept.
- Single-sourcing creates supply risk. Keep a qualified secondary.
