Have You Ever Hesitated to Reply When a Supplier Asked Too Many Questions?
Created on 08.26
What those questions really mean when you are sourcing a custom metal part — and why a clearer conversation can lead to a more useful quotation.
You send a supplier a drawing, a few photos, or perhaps just a description of the part you need.
You are expecting a price.
Instead, more questions come back.
What material is it?
How many pieces do you need?
Is this a one-time order or could there be repeat demand?
Do you need a raw casting or a fully machined part?
Where will the part be used?
Do you have a 3D model?
At some point, it is understandable to think:
“I only wanted a price. Why is this becoming so complicated?”
And if you are a distributor, purchasing person or someone who simply does not have all the technical information, you may think:
“I don’t know all of these answers. Maybe I should just ask another supplier.”
If you have ever felt that way, you are not alone.
But with custom metal parts, those questions are often not standing between you and the quotation.
They are part of creating a quotation that actually means something.
A price has to be based on something
For a standard product, quoting can be very simple.
If you give a clear part number, specification and quantity, the product has already been defined. The tooling may already exist, production may already be running in large volumes, and the supplier may even have stock ready to ship.
Custom manufacturing is different.
If a part has to be made specifically from your drawing, sample or application, the supplier first needs to understand what is actually being priced.
Material, size, weight, quantity, manufacturing process, tooling, machining, tolerances, heat treatment, inspection and final delivery condition can all affect the cost.
If too many of those things are unknown, a supplier can still give you a number.
But what is that number based on?
If the material is assumed, the weight is guessed, the quantity is unclear and the machining scope is not defined, the supplier may no longer be pricing your actual requirement.
They are pricing an imagined version of it.
A quick number can still be useful, but only when everyone understands the assumptions behind it.
“I’m only checking whether this is worth doing”
This is a very normal situation.
Perhaps you already buy a replacement part somewhere else. You are not ready to change suppliers yet.
You simply want to know:
“If I have this part custom-made, would the cost be much higher, much lower, or roughly the same?”
That is a perfectly reasonable question.
You may not want to pay for 3D scanning, ship a sample internationally or prepare complete drawings before you even know whether the idea makes economic sense.
In that case, you may not need a production-ready quotation yet.
A budgetary estimate may be enough to help you decide whether the project is worth taking further.
But even a rough estimate needs a reasonable foundation.
Clear photos, approximate dimensions, weight, material if known, expected quantity, basic machining requirements and some information about the application can make a big difference.
Your current purchase price is based on a real product.
Our estimate should also be based on something reasonably close to that real product — not simply on imagination.
This matters even more if the product you currently buy is a standard mass-produced part.
Its tooling may have been paid for years ago. Thousands of pieces may be produced at one time. The process may already be highly optimized.
A newly developed custom part starts from a different cost structure.
That does not automatically mean custom manufacturing is not worthwhile.
It simply means the comparison has to be made on the right basis.
Sometimes the answer will be:
“Yes, it is worth developing.”
Sometimes it will be:
“For this quantity and this application, continuing to buy the existing part may make more sense.”
Either answer is useful if it helps you make a better decision.
The real quantity is more useful than the biggest quantity
Quantity is another question that sometimes makes buyers hesitate.
A customer may only need five pieces and worry that the supplier will not be interested.
So instead of saying five, they may say:
“Future quantity could be 5,000 pieces.”
They may hope that a larger quantity will lead to a lower quotation.
But in custom manufacturing, quantity does more than change the unit price.
It can change the manufacturing plan itself.
If you genuinely need only a few pieces for a trial, replacement or market test, a simpler tooling solution or another manufacturing route may make more sense.
The tooling cost may be lower, while the unit price is somewhat higher.
For a small initial order, that may be the most economical solution overall.
If the same part is expected to enter stable repeat production, the approach may be completely different.
A more durable mold, pattern, fixture or production setup may require more investment at the beginning, but provide better efficiency, consistency and unit cost over larger volumes.
So an unrealistically high future quantity does not always make the first quotation cheaper.
Sometimes it does the opposite.
The supplier may prepare a long-term production solution for a future that you do not actually need yet.
A much more useful conversation is simply:
"I need five pieces now. I am testing the market. If it works, there may be repeat orders later, but I do not know the quantity yet."
Now the supplier understands the real situation.
One solution can be considered for the first small order, while another cost expectation can be discussed for future volume production.
That gives you something more useful than one price:
you can understand both the cost of testing the market today and what the economics may look like if the market develops later.
The most useful quantity is not the biggest number. It is the most realistic number you know today.
And if you genuinely do not know yet, that is also useful information.
Sometimes the order is small, but the material problem is not
We once reviewed a small order containing several different custom parts.
The quantities were low, but some of the specified materials were not grades that would normally be used regularly in production.
Technically, the parts could be made.
The difficulty was somewhere else.
To produce the small number of finished parts, the required raw material itself could only be purchased in a much larger minimum quantity.
Imagine that your parts only consume a small amount of a special material, but the material supplier requires us to purchase enough material for many more parts.
What happens to the remainder?
If it is a common grade that can easily be used on other projects, the issue may be manageable.
If it is a special material unlikely to be used again soon, the economics become very different.
Should the full minimum material cost be included in the current order?
Could the quantity be increased?
Could the customer provide the material?
Is there an acceptable alternative material that meets the actual performance requirement?
These are not questions a manufacturer should quietly answer on the customer’s behalf.
The buyer understands the commercial situation and future demand.
The manufacturer understands the material sourcing conditions and production implications.
Neither side has the complete picture alone.
This is exactly why communication matters.
“I don’t have a drawing”
That does not necessarily mean the project has to stop.
Many real sourcing projects begin with much less.
Sometimes there is only an old part.
Sometimes there is a general assembly drawing but no individual manufacturing drawing.
Sometimes there are only photos and a few main dimensions.
Sometimes the original supplier is gone and the customer is simply trying to keep older equipment running.
The first question is not always:
"Do you have a complete drawing?"
It may be:
"What do you have, and what are you trying to achieve?"
If you have an existing part, you can start with clear photos, main dimensions, weight, material information if known, quantity and application details.
If the project looks worthwhile, the next step may be 3D scanning, reverse engineering, more detailed measurement or sending a sample for review.
An old sample also needs some judgment.
A worn sealing surface, bearing bore or mating dimension should not automatically be copied simply because that is what the used part measures today.
The real goal is not simply to reproduce the shape.
It is to produce a new part that fits and works as required.
What if you simply do not know the answer?
That is normal too.
Not every person requesting a quotation is the engineer who designed the equipment.
You may be a distributor, sourcing company, purchasing person or someone testing a new market.
When a supplier asks about working temperature, pressure, material properties or final application, you may genuinely not know.
You do not need to invent an answer.
You can simply say:
“I don’t know yet.”
Or:
"My customer has not confirmed this."
Or:
"I am only checking whether this project makes commercial sense before going further."
Those are useful answers because they tell the manufacturer where the project really stands.
A good technical conversation is not a test of how much the buyer knows.
It is a way to separate what we already know, what is still uncertain, and what really needs to be confirmed before the next step.
Sometimes we can make a preliminary estimate first.
Sometimes we can suggest what should be checked with the end user.
Sometimes the application itself gives enough information to discuss a likely material or manufacturing route.
You do not need to arrive with every answer.
But it helps enormously if both sides are open about what is known and what is not.
Why not just quote first and sort everything out later?
Because the quotation is not the end of the project.
If the order moves forward, the part eventually has to be made.
Material has to be purchased.
Tooling may have to be prepared.
The blank has to be produced.
Machining has to follow a defined requirement.
Critical dimensions have to be inspected.
And finally, the part has to fit into the customer’s equipment and do its job.
If the quotation is built on the wrong understanding, that misunderstanding does not disappear when the purchase order arrives.
It follows the project.
A wrong material assumption can become the wrong material.
An unclear machining scope can become an unfinished part.
A wrong quantity assumption can lead to the wrong tooling strategy.
A missing functional requirement can produce a part that looks correct but still does not work in the final assembly.
That is why, for a custom part, a quotation is more than a number.
It is one of the first results of understanding the product correctly.
Sometimes a few questions make the whole project faster
If you already know the exact medicine you need, buying it is straightforward.
But if all you know is:
“My stomach hurts.”
A doctor needs more information before deciding what treatment makes sense.
The extra questions are there because the right solution depends on understanding the problem.
Custom manufacturing can be similar.
When everything is already clearly defined, quoting can be very fast.
When it is not, a few questions at the beginning may prevent the whole project from moving quickly in the wrong direction.
A clearer foundation can reduce repeated quotations, drawing revisions, tooling changes and production misunderstandings later.
So the better question is not always:
“Who gave me a price first?”
It may be:
“Which quotation gives me enough clarity to make a real purchasing decision?”
A useful quotation starts with an honest conversation
You do not need to know everything before contacting a manufacturer.
Tell us what you know.
Tell us what you do not know.
Tell us what you are trying to achieve.
If you only want a rough cost comparison, say so.
If you only need three pieces, say three pieces.
If future quantity is uncertain, say it is uncertain.
If you only have an old sample, start there.
If you are a distributor and need to check something with the end user, that is fine too.
Incomplete but truthful information is usually more useful than complete information built on the wrong assumptions.
A quotation should help you understand not only the number, but what the number represents:
the material,
the quantity,
the manufacturing route,
the tooling,
the machining,
and what still needs to be confirmed.
At Unna Metal, this is how we prefer to approach custom projects.
You can come to us with a complete drawing, an old sample, a few photos, or simply a project you are still trying to evaluate.
We may have questions.
You may not have every answer.
That is fine.
Tell us what you know, what you do not know, and what you are trying to achieve. Then we can work through the rest together.
