Choose a packaging supplier on four things: whether they specify before they quote, whether they can supply the whole line list rather than part of it, whether they can hold run quantities so you are not storing them, and whether they will tell you when a cheaper option would do. Price per unit is the easiest thing to compare and the least informative.
The question most buyers ask first, and why it misleads
Most supplier selection starts with a price list. It is the fastest comparison available and it quietly assumes the thing being priced is the right thing.
A supplier who sells you the carton you asked for has done their job. A supplier who asks what you are putting in it, how it travels and what is arriving damaged may quote a different format at a different price - and that comparison is the one that matters.
Four things that separate suppliers in practice
- Do they specify before they quote? If the first question is 'what size box do you want' rather than 'what are you packing', you are buying a catalogue item and the specification risk stays with you.
- Can they supply the whole list? Cartons, mailers, tape, fill, film, strapping and protective on one account removes real administrative cost and makes the pack coherent. See packaging supplies.
- Can they hold stock? Printed and bespoke lines come in run quantities. If the supplier cannot hold them, you either order short at a worse price or fill your own unit with board. packaging stockholding is the alternative.
- Will they talk you down? A supplier who tells you a standard line would do the job, or that a substitution would increase damage, is worth more than one who agrees with everything.
Questions worth asking before you commit
- What specification are you quoting - board construction, internal dimensions, finish?
- Where are the quantity breaks, and what is the economic run for this line?
- Is any setup cost separate, and over what quantity is it spread?
- Can you hold the run and release it on call-off, and on what terms?
- What lead time applies to a reorder, and is the stock already made?
- Will you sample a bespoke or printed line before the production run?
- If our product changes, what happens to the tooling or plates?
The reorder-lead-time question is more revealing than it sounds. If the stock is already manufactured, a reorder is a delivery. If it is not, a reorder is a production slot - and that is the difference between a replenishment and a stopped pack bench.
Capability versus range
There is a real distinction between a supplier with a wide catalogue and one with specification capability. Both can sell you boxes; only one can tell you that your damage problem is movement rather than impact and that the answer is a fitted insert rather than more bubble wrap.
| Signal | What it suggests |
|---|---|
| Asks for product dimensions and weight before quoting | Specification capability rather than order-taking |
| Asks how the goods travel - parcel, pallet, retail backroom | Understands that the journey changes the pack |
| Asks to see damaged returns | Diagnoses cause rather than selling padding |
| Offers a sample before a production run | Expects to be held to the specification |
| Can quote standard and bespoke against each other | Not committed to selling you the expensive option |
What to look for, and what it tells you.
Does it matter where they are?
Less than people expect, for consumables. What matters is whether the stock is held and already made, and whether delivery into your postcode is a routine run rather than an exception.
WSUK supplies from the Midlands Golden Triangle, which is where the national road network converges - that is what makes UK-wide supply from a single stock holding practical. The full service is national rather than regional.
The advantage of a supplier who also runs the operation
A packaging supplier that also stores goods, picks and packs orders and despatches parcels has had to hit a cut-off using the materials it sells. That changes the specification conversation - box ladder depth, how materials present at the bench and what happens when a line runs out mid-shift become real questions rather than theoretical ones.
It also means the packaging can sit where it is used. See packaging for fulfilment and fulfilment services.
The short version
- A supplier who asks what you are packing beats one who asks what box you want.
- Check they can supply the whole line list, not part of it.
- Ask whether they can hold a run quantity on call-off.
- A supplier who talks you down to a cheaper option is worth keeping.
- Ask whether a reorder is a delivery or a production slot.
Frequently asked questions
Should we use one supplier or several?
One, for the consumables at least. Splitting cartons, tape and fill across three suppliers generates more administrative cost than the price difference usually saves, and nobody ends up responsible for whether the pack works as a whole.
How important is price in the decision?
It matters, but compare delivered cost per order rather than price per unit. A cheaper box that needs more fill and attracts a volumetric surcharge is not cheaper.
What if we do not know what we need?
That is normal and it is the supplier's job. Describe the product, how it travels and what is going wrong, and a capable supplier will specify it. See packaging services.
Should the supplier hold our stock?
If you buy anything printed or bespoke, almost certainly. Those come in economic run quantities and board is a poor use of space you pay for - see packaging stockholding.
How do we compare quotes fairly?
Insist on the same written specification from each, then compare on delivered cost per order. Our guide to comparing packaging suppliers sets out the method.
