How to brief a custom product when the idea is still vague: fields, questions and an example

A vague idea is a normal starting point

Most private-label projects begin with a sentence rather than a specification: "a premium ginger shot for our cafés" or "a tea blend with our name on it". That is a reasonable place to start. The risk is not vagueness itself; it is asking a supplier to quote or sample against a sentence, then discovering three rounds later that everyone pictured a different product. A short written brief closes that gap. It needs to show which answers are known, which are assumptions and which must be decided before a sample is worth making.

The four questions to answer before anything else

Before format, flavour or packaging, define the commercial hypothesis behind the product. Four questions do most of the work:

• Who buys it: the end customer, and the person inside your business who approves it.
• Where they buy or use it: shelf, menu, guest room, treatment room, online, or a distributor's range.
• When they use it: daily, occasionally, as a gift, as part of a service.
• What they should be willing to pay, and therefore what landed cost the product must sit within.

If you cannot answer these yet, the honest brief says so. A sample made without a price hypothesis often turns out to be a lovely product nobody can sell at a margin.

The product brief, field by field

Once the hypothesis is written down, turn it into a brief a supplier can act on. Use these fields and mark each one as confirmed, assumed or open:

• Product concept: one or two plain sentences, plus any reference products you admire.
• Format and size: liquid, powder, bar, sachet, garment; the unit size and pack count you expect.
• Key attributes: taste, scent, texture, colour, ingredients to include or avoid, performance expectations.
• Claims you hope to make: these drive evidence requirements and may need professional or regulatory review for the destination market.
• Destination market and channel: country of sale, retail or food-service, any labelling or import rules you already know apply.
• Packaging: primary pack, outer carton, branding, artwork ownership and who supplies the design.
• Documentation needs: specifications, certificates such as Halal, Kosher, ISO, HACCP or organic where relevant, and test reports customers will expect.
• Volume range: first order and a realistic repeat range, rather than a single optimistic number.
• Target price: unit cost or landed cost, and whether freight is included in your thinking.
• Timing: launch date, the date working back from it when you need approved samples, and any fixed events.
• Decision makers: who approves the sample, the artwork and the final specification.

A hypothetical brief, filled in

For example, imagine a café group that wants a house-brand wellness shot. A first-pass brief might read like this. Concept: a ginger and turmeric shot sold chilled at the counter, less sweet than the leading supermarket option. Format: a small single-serve bottle, sold individually. Attributes: noticeable ginger heat, no added colours, a short ingredient list. Claims: none beyond the ingredient description at this stage, flagged as open. Market: cafés in one Australian state, food-service channel. Packaging: the group's existing brand style, with artwork to be produced by their designer. Volume: an illustrative first order of a few thousand units, with repeats depending on sell-through. Target price: an illustrative counter price, from which the group works back to a maximum landed cost. Timing: a menu change in about six months. Approver: the operations manager for taste, the marketing lead for artwork.

This hypothetical brief contains no final recipe, shelf-life figure or confirmed price; those come from development and sampling. It does contain enough for a supplier to say which parts are straightforward, which carry cost or timing risk and which need a decision first.

Questions that make the first sample testable

A sample is only useful if you know what it is testing. Before one is made, agree the answers to a handful of questions:

• What is this sample meant to prove: taste direction, pack format, colour, or overall concept?
• Is it an existing product being considered as-is, or the first step in a development brief?
• Which attributes will you judge, and against what reference?
• Who will evaluate it, in what setting, and how will feedback be recorded?
• What would make you reject it, and what would make you move to the next round?

Writing the criteria down first prevents vague "we like it, but…" feedback. At Klense Supply, samples are paid and quoted separately, which is another reason to make each round count. A sample may be an existing product from the range or part of a development brief, and the brief determines which route is sensible.

How the brief moves into a proposal

When you request a discovery call, the brief becomes the agenda. The commercial contact works through scope with you, identifies what is known and what needs validation, and prepares a proposal confirming scope, pricing, minimum quantities, packaging, sampling, payment stages and indicative dates. Once the scope is agreed, an operations contact is introduced to coordinate samples, production and delivery. Clearly marked assumptions make that proposal more accurate, because the gaps are visible rather than hidden inside a unit price.

Frequently asked questions

How much detail does a first custom product brief need?

Enough to describe the customer, channel, format, target price and timing, with every uncertain field marked as an assumption. A one-page brief with honest gaps is more useful than a long document that presents guesses as requirements.

Should we ask for samples before we have a target price?

It is usually better not to. Without a price hypothesis, a sample can steer development towards ingredients, packaging or formats the product cannot support commercially. Even a rough landed-cost ceiling helps.

What if our idea falls outside the listed product categories?

Custom sourcing beyond the listed range is possible. The same brief applies: describe the product, market, volume and timing, and the commercial contact will assess whether it is a sound fit before any sample is quoted.
