How to Negotiate a Lower Unit Price With a Factory You Already Use

Asking for a discount gets you 3 percent. Changing what the factory pays for gets you 15. Here is how to get a cost breakdown out of your supplier, which levers move the number most, and the one rule that stops a spec change from quietly wrecking your product.
Most founders try to get a better price by asking for one. They send an email saying the price is too high and can the factory do better. They get 3 percent, or nothing, and they stop asking.
That is not how factory pricing works. A unit price is built from parts. If you want it to move, you have to change one of the parts. This is the process we run for clients who are already in production and want their cost down before the next order.
Can you actually get a lower price after production has started?
Yes, but only at the reorder, and only if you change something the factory pays for.
Mid-run is the wrong moment. The materials are bought, the line is booked, and anything you ask for is a favour. At the reorder you are a real order in a quoting window, and the factory has not yet committed the material spend. That is the only point where the number is genuinely soft.
The reductions we see on a properly worked reorder sit between 8 and 18 percent. Asking for a flat discount, with nothing else changed, gets you 2 to 5 percent if you have paid on time and the relationship is good.
What is actually inside your unit price?
For a typical small-run consumer product made in Asia, a quoted unit price breaks down roughly like this. Treat these as illustrative ranges, not your numbers.
- Materials and components: 40 to 60 percent
- Labour: 10 to 20 percent
- Packaging: 5 to 15 percent
- Factory overhead and margin: 10 to 25 percent
- Scrap and yield allowance: 2 to 8 percent
Read that list again and notice what "give me 10 percent off" is actually asking. It asks the factory to hand over most of its margin and keep everything else the same. No factory does that twice, and the ones that do usually claw it back somewhere you cannot see. Thinner plating. A cheaper zip. A different resin.
The money is in materials and packaging. That is where you should be pushing.
Which levers move the price most?
Ranked by how much they actually shift the number, not by how easy they are to ask for.
1. Committed volume, not a bigger single order
Factories price against machine time and material buys. A single larger order helps. A committed twelve month forecast with scheduled call-offs helps far more, because it lets them buy material once and schedule the line. You do not have to pay for it all upfront. You have to commit to it in writing.
2. Materials and spec
This is the biggest single slice and the one nobody touches. Ask what a grade change does to the price. Ask what a thickness change does. Ask what dropping from a four colour print to two does. Every one of those is a real number the factory can quote in a day.
3. Packaging
Packaging is often 10 percent of your unit price and almost never re-quoted after the first run. Shrinking a retail box by 10mm can change how many units fit a carton, which changes how many cartons fit a pallet, which changes your freight. You get paid twice for the same change.
4. Payment terms
Cash flow is worth money to a factory. Moving from 30/70 to 50/50, or paying the deposit within 48 hours instead of on their reminder, is worth asking a price against. Do not give it away for free. Ask what it buys. If you are unclear on the standard structures, start with factory payment terms explained.
5. Your own reject rate
If your product has a high failure rate at final inspection, the factory has priced that into every unit you buy. Fixing an ambiguous tolerance on your drawing can be worth more than any negotiation.
What to send the factory
Ask for a cost breakdown. Not a lower price. A breakdown.
Request the quote split into: materials, labour, packaging, overhead and margin, tooling amortisation, and scrap allowance. For materials, ask for the spec by name and grade, the price per kilo or per metre, and the quantity used per unit.
Say why you are asking. Something like: we have a target price of X for the next order and we want to understand which part of the build to change, rather than asking you to cut your margin.
Roughly half of factories will refuse a full breakdown. Most will give you materials and packaging. That is enough to work with.
A worked example
A homewares client, 5,000 units, quoted at $6.40. The breakdown that came back:
- Materials $3.20
- Labour $0.90
- Packaging $0.75
- Overhead and margin $1.15
- Scrap allowance $0.40
What changed:
- Retail box reduced from 130mm to 118mm. Sixty units per carton instead of forty-eight. Packaging drops from $0.75 to $0.52.
- Inner sleeve print dropped from four colours to two. Materials $3.20 to $3.02.
- Committed to 5,000 now plus 5,000 in four months, one material purchase. Materials to $2.90, labour to $0.82.
- Payment moved from 30/70 to 50/50. Another $0.10.
New unit price $5.44. Down 15 percent. On 10,000 units that is $9,600, and the carton change took another slice off the freight because more units fit the same container. None of it came out of the factory's margin, which is why the price held on the run after that.
Then put the saving back through your landed cost per unit before you celebrate. The factory price is one line of six.
What you should never cut
Some savings are not savings.
- Anything with a compliance or safety function. Fasteners, seams, electrical parts, anything that touches skin or food.
- Your pre-shipment inspection. Cutting QC to save a few hundred dollars is the cheapest way to lose a container.
- Material grade on a load-bearing part, unless an engineer has signed off.
- The finish a customer sees and touches first. A returns spike will cost more than the cent you saved.
And one rule with no exceptions. Every spec change gets a new sample, a newly signed golden sample, and the change written into the purchase order. A verbal agreement about material grade will not survive the third production run or a change of sales rep.
When is the best time to ask?
- At the reorder, before the purchase order is issued. Never mid-run.
- In the low season. For China that is roughly the weeks after Chinese New Year and again in late spring, when order books are thin. Avoid August to October, which is peak.
- After you have paid on time at least twice. Payment history is leverage and it is the only kind you build for free.
- When you are physically there. Prices move differently across a table than over WeChat. That is a large part of why we run sourcing trips, with China in October for Canton Fair Phases Two and Three.
What if they say no?
Get a second quote, but quote the same specification sheet, not a description of your product. Most of the "I found it 30 percent cheaper" quotes founders bring us are priced against a different material.
If the second quote comes back more than about 12 percent under, check the material grade line by line before you get excited. Nine times out of ten the gap is a spec difference, not a pricing difference.
If it is real and you decide to move, understand what you own first. Read who owns the mould and how to switch factories without losing your tooling before you tell anyone anything.
Common mistakes
- Asking for a percentage instead of naming a target price. Give them a number to solve for.
- Negotiating against a quote you never specced properly in the first place.
- Accepting a lower unit price that comes with a higher minimum you cannot fund. If cash is the constraint, work on lowering the MOQ instead.
- Confusing a lower unit price with a lower landed cost. Moving from DDP to FOB will change your quoted number without changing what you actually pay. See Incoterms explained.
- Winning the saving and leaving your retail price where it was. What you do with the margin is a separate decision, and Kristy covers it in how to price a product so wholesale doesn't kill you.
The checklist
- Wait for the reorder window.
- Request a cost breakdown, with materials split by spec, grade and quantity per unit.
- Name a target price and say what it is for.
- Quote three spec changes: packaging dimensions, one material or finish change, one print or component simplification.
- Offer a committed twelve month forecast with call-offs.
- Ask what better payment terms buy you.
- Get a new sample for every change and sign a new golden sample.
- Write every change into the purchase order.
- Recalculate landed cost, not just unit price.
The takeaway
You do not negotiate a factory price down. You rebuild it. Ask what the parts cost, change the parts you can change, and leave the parts that protect the product alone. Done properly it is worth 8 to 18 percent, it holds on the next run, and nobody quietly swaps your material to pay for it.
If you are already making and selling and you suspect you are paying too much, we can look at your quote and tell you where the money is. Book a sourcing call and we will tell you honestly whether we can help.
Frequently asked questions
Can you renegotiate a price with a factory mid-production?
Not realistically. Once materials are bought and the line is booked, any reduction is a favour rather than a commercial decision. The reorder, before the purchase order is issued, is the only point where the price is genuinely soft.
How much can you expect a factory price to come down?
A flat discount request with nothing else changed typically gets 2 to 5 percent. A properly worked reorder, where packaging, materials and volume commitments all change, usually lands between 8 and 18 percent.
Will a factory give you a cost breakdown?
Around half will refuse a full breakdown. Most will give you materials and packaging if you explain you are trying to hit a target price rather than cut their margin, and that is usually enough to work with.
