Consolidating packaging suppliers helps when it shortens the line list and makes the whole cost visible - materials, storage, carriage, labour, damage and waste interact, and nobody can see that across four accounts. Moving the same badly-specified list to one supplier changes the invoice and nothing else.
What consolidating actually changes
The usual argument for one account is buying power, and it is the least interesting one. The real gain is visibility: when packaging arrives from four suppliers, nobody holds the whole picture, and the interactions between material cost, pack time, carrier band and damage are invisible by construction.
The second gain is that one list can be edited. Ranges accumulate because adding a line is easy and removing one needs somebody to own the decision. A single account is the natural moment to ask which lines are doing real work.
| Claim | Reality |
|---|---|
| Better unit price | Sometimes, and usually the smallest effect |
| Fewer invoices and deliveries | Yes, and it saves genuine admin time |
| Whole-cost visibility | Yes - this is the main benefit |
| A shorter line list | Only if somebody actually edits it |
| Better specification | Only if the supplier specifies rather than quotes |
| Less risk | No - concentration is a risk, manage it deliberately |
What one account changes, and what it does not.
When not to consolidate
Consolidation is not automatically right. If a specialist line is genuinely better from a specialist, keeping it is sensible. If one supplier's service is the only reliable thing about your despatch, moving it to prove a point is a poor trade.
- Keep a line where the specialist product is materially better and the volume is small.
- Keep a second source on anything that would stop despatch if it failed.
- Do not consolidate during a peak - see Packaging for a Seasonal Peak.
- Do not consolidate printed stock mid-run without settling who owns what is already made.
Doing it so it is worth doing
- Build one list across every current supplier, with twelve months of usage against each line.
- Mark each line continuous, seasonal or occasional - they behave differently and should be treated differently.
- Ask what should be removed, not just what it would cost. A supplier who only adds lines is selling.
- Re-specify the lines that are doing a job another material would do better, rather than re-pricing them.
- Move in sequence rather than all at once - see Switching Packaging Supplier Without Disrupting Despatch.
The finding that matters is rarely the price. It is usually that the range is longer than the despatch profile needs, and that a third of the packs are mostly air.
What the first conversation should cover
If you are considering moving to one account, the first conversation is worth steering. A supplier who answers only on price is quoting; one who asks about the product and the journey is specifying, and those produce very different outcomes.
- "What would you take off this list?" - a supplier who only adds lines is selling.
- "Which of these materials is doing a job another one would do better?"
- "What proportion of our despatches do you think are oversized?" - and then check it against carrier invoices.
- "What is held in stock and what is made to order?"
- "How would you handle our printed lines if we cannot store a full run?" - see packaging stockholding.
- "When would you tell us a change is not worth making?"
The answers to those tell you more than a price comparison, because a like-for-like quote against a list nobody designed prices the wrong things accurately. A proper look at the operation is a packaging review rather than a quotation.
What a single line list usually reveals
The first useful output of consolidating is not a price. It is the document itself - every packaging line from every supplier, with twelve months of usage against each, on one page. Most businesses have never seen that, and it tends to answer the question before anybody quotes.
| Finding | Why it happens | What it is worth |
|---|---|---|
| Duplicate lines from two suppliers | Nobody cancelled the first | Immediate, with no downside |
| Sizes with no movement in a year | Added for a product since changed | Cash and floor space |
| Two materials doing one job | Bought by different people at different times | Simplifies the bench too |
| A size used for almost everything | The ladder has collapsed in practice | Signals a re-specification |
| Heavy fill consumption | Compensating for poor carton fit | Usually the largest single item |
| No protective specification at all | Damage treated as a carrier problem | Shows up as credits |
What the combined list typically shows.
None of those findings require a supplier change to act on. That is worth saying plainly: if building the list is all you do, it will still have been worth doing. A proper look at what the six cost areas are doing to each other is a packaging review.
The short version
- The main benefit is visibility across all six cost areas, not unit price.
- A single list is the one that can actually be edited.
- Keep a second source on anything that would stop despatch.
- Ask a prospective supplier what they would remove from the list.
- Move in sequence, and never during a peak.
Frequently asked questions
Does using one packaging supplier save money?
Sometimes on price, and more reliably through a shorter, better-specified range. The saving comes from editing the list and fixing the fit rather than from the consolidation itself.
Is it risky to depend on one supplier?
Concentration is a real risk and worth managing deliberately - keep a second source on anything whose failure would stop despatch, and understand what is held in stock versus made to order.
We buy from four suppliers. Where do we start?
Build one list across all four with usage against every line. That single document usually answers the question before anybody quotes, because it shows the duplication straight away.
Will you quote against our existing list?
Yes, though we would rather look at what you despatch first. Quoting like-for-like prices the list accurately and says nothing about whether the list is right - see packaging review and cost reduction.
Can one account cover boxes, tape, foam and pallet consumables?
Yes, along with printed and bespoke work. That is the point of it - see packaging supplies.
