What Information Do Suppliers Need to Quote a Custom Product Accurately?

A custom product quotation can look simple: send a picture, state a quantity and ask for a price.

In practice, that often produces a quote that is difficult to compare, incomplete or based on assumptions the buyer never intended.

For custom souvenirs, branded merchandise and creative products, price is usually connected to a combination of product format, size, material, artwork, manufacturing process, quantity, packaging and delivery requirements.

The clearer those inputs are, the more useful the quotation becomes.

That does not mean every buyer needs a finished specification before contacting a supplier. Early-stage projects often begin with only a concept, reference image or rough idea.

The goal of a good RFQ is not to know everything.

It is to make clear what is already decided, what is flexible and what still needs supplier input.

1. Start with the product format

The first question is straightforward:

What are you trying to make?

A magnet, keychain, pin, coin, bookmark, plush item and resin figure may all use the same artwork, but their production methods, tooling requirements, minimum quantities and price structures can be very different.

A request such as:

“We want a souvenir using this artwork.”

is therefore still too broad for an accurate quotation.

A better starting point would be:

“We are considering a metal magnet, keychain and pin using the same destination artwork. Please advise which formats are most suitable for a first production run.”

That gives the supplier enough direction while still leaving room for useful recommendations.

For buyers developing an entire merchandise collection, it is often useful to identify both the preferred format and acceptable alternatives.

2. Give approximate dimensions

Size affects material consumption, tooling, weight, packaging and shipping.

Even an approximate dimension is much more useful than none.

For example:

60 × 45 mm magnet

provides significantly more information than:

standard-size magnet

because “standard” can mean different things to different factories and product categories.

If the final dimensions have not been decided, give a range.

For example:

approximately 50–70 mm wide

This allows suppliers to recommend a practical size while still producing a meaningful estimate.

3. Be clear about material — or say when you are flexible

Material is often one of the biggest price variables.

A buyer may know exactly what is required:

zinc alloy with soft enamel

or may only know the desired visual result:

a premium metal souvenir with an antique brass appearance

Both can work.

The important part is telling the supplier whether the material is fixed, preferred or open to recommendation.

This prevents a common quotation problem: different suppliers quoting entirely different constructions and producing prices that appear comparable but actually describe different products.

When material flexibility exists, asking for alternatives can also be valuable.

For example:

“Please quote your recommended standard material and one lower-cost alternative if available.”

That turns the RFQ into a sourcing conversation rather than a simple price request.

4. Provide usable artwork or a clear reference

Custom products usually depend on artwork.

The ideal situation is a vector file such as AI, EPS, SVG or editable PDF, but many early-stage buyers will not have production-ready artwork yet.

That is fine.

A supplier can often begin with:

If a supplier needs to redraw artwork, simplify details or prepare production files, that work may become part of the development process.

• a reference photo
• rough drawing
• logo
• destination image
• character artwork
• packaging example
• visual mood board

What matters is explaining whether the reference is final artwork, inspiration only or something that still needs development.

This distinction affects both price and timeline.

5. State the customization level

“Custom” can mean very different things.

Adding a logo to an existing product is not the same as developing a completely new shape.

A useful RFQ should therefore indicate the expected level of customization.

For example:

existing shape + custom print

is different from:

custom shape + new mold + custom packaging

and different again from:

full product development from concept.

This matters because tooling, sampling and development costs usually increase as customization becomes deeper.

For caldvane-type projects, it is useful to think about customization as a spectrum rather than a yes/no question.

6. Give a realistic quantity — and ask for price breaks

Quantity affects almost every custom product quote.

Instead of asking only:

“What is your MOQ?”

it is usually more useful to tell the supplier the quantity you are actually considering.

For example:

“Initial order: approximately 500–1,000 pieces. Please quote 500 / 1,000 / 3,000 pieces.”

This allows the buyer to see how unit economics change as volume increases.

It also helps distinguish three different ideas that are often confused:

minimum MOQ

recommended production quantity

best-price quantity

A factory may technically accept 100 pieces but produce much more efficient pricing at 1,000 pieces.

Those are both useful pieces of information.

7. Include packaging expectations early

Packaging is frequently discussed too late.

That can create unexpected changes in unit cost, carton dimensions, presentation quality and lead time.

Even if packaging has not been finalized, the RFQ should say something such as:

“Individual polybag acceptable for initial quote.”

or:

“Retail-ready packaging will be required; please quote basic packaging separately.”

For museum shops, resorts, attractions and branded merchandise, packaging can also be part of the customer experience rather than simply protection during transport.

That means it may need to be considered earlier in the project.

8. Tell suppliers where the product is going

The destination market can affect packaging, labeling, documentation, testing and compliance requirements.

A supplier quoting a promotional item for one market may make different assumptions from a supplier quoting a children’s product, food-contact item or product intended for a major retailer.

At minimum, provide the expected destination country or region.

If you already know that specific testing, labeling or certification will be required, state that in the RFQ rather than waiting until after the quote.

9. Include your required timeline

A quotation without a timeline can be misleading.

There is a major difference between:

“We need delivery within six weeks.”

and:

“This is an early-stage project planned for next season.”

Suppliers need to understand whether the request is exploratory, entering sampling, preparing for production or tied to a fixed launch date.

A realistic timeline allows them to assess tooling, sampling, production capacity and shipping method properly.

10. Should you give suppliers a target price?

When used correctly, a target price can be extremely useful.

It does not have to mean:

“This is the maximum price we will pay.”

Instead, it can communicate commercial positioning.

For example:

“Our target retail price is approximately USD 12–15, and we would like to understand which product construction would be commercially realistic.”

That gives the supplier room to recommend materials, dimensions and processes rather than quoting a technically impressive product that is unsuitable for the buyer’s intended market.

A practical custom-product RFQ checklist

Before sending an RFQ, it helps to check whether the following information is available, estimated or intentionally left open for supplier recommendation.

What if you do not know all of this yet?

Do not invent specifications just to complete the RFQ.

Mark uncertain items as:

• TBD
• open to recommendation
• please advise

A useful supplier should be able to help narrow the options.

“Material: open to supplier recommendation. The priority is a durable premium finish suitable for museum retail.”

That is more useful than randomly specifying a material that may not fit the product.

The best RFQs create enough structure for suppliers to quote while still leaving room for manufacturing knowledge to improve the product.

Why very short RFQs often produce very different prices

Suppose three suppliers receive this request:

“Please quote 1,000 custom magnets using the attached artwork.”

Supplier A may assume a printed metal magnet.

Supplier B may assume a zinc-alloy molded magnet.

Supplier C may assume an acrylic magnet.

All three quotes may be legitimate.

But the buyer is comparing three different products.

This is one reason unusually low or unusually high quotations should not immediately be interpreted as evidence that one supplier is cheaper or more expensive.

First check whether everyone is quoting the same thing.

A better RFQ is not necessarily a longer RFQ

The goal is clarity, not paperwork.

A well-structured one-page brief with a reference image can often be more useful than a long document filled with information that does not affect production.

For most custom merchandise projects, the supplier needs to understand four things:

• what you want to make
• what has already been decided
• what remains flexible
• what commercial constraints the product needs to meet

Once those are clear, the quotation becomes much more useful as a product-development tool rather than simply a number.
