Paying a supplier
What the deposit covers and when the balance should move.
Read guide →Updated September 28, 2026 · by the Qula Craft Sourcing Team — the people who quote and pack these lines every week.

| Sample type | What it proves | When to ask |
|---|---|---|
| Stock sample | Real material, finish and size of an existing line | Before a first order from a new supplier |
| Colour / mix sample | Your palette or ratio, on an existing shape | When you are customising a stock design |
| Pre-production sample | The actual run, from the actual mould, in the actual pack | Always, on custom work, before mass production |
Confusing the first and the third is a classic and expensive mistake. A stock sample tells you the factory can make good goods. Only a pre-production sample tells you your goods are right.
On highly detailed resin designs you may notice small differences between orders. That is not necessarily carelessness. Mixing the two resin components causes an exothermic reaction that generates heat, and that heat plus the casting compounds degrades the mould — a flexible mould typically yields between 25 and 100 castings before it starts losing fine detail.
What to do with that knowledge:
For a first order at craft-supply values, a full third-party inspection often costs more than the goods. Cheaper checks that catch most problems:
Once your order values justify it, a third-party inspection at the factory before shipment is the standard next step.
For custom projects, agree the digital proof, prototype or pre-production sample needed, sample fees and timing by email. Confirm packaging and inspection criteria with the quotation. Any requested product reports or additional testing are reviewed for the specific design, material and target market before order acceptance.
Sample fees and whether they are credited against a bulk order are confirmed per project — ask in the enquiry and it will be in writing on the quotation.
Tell us which designs and what you need the sample to prove — colour match, size, pack format. Sample options, fees and timing are confirmed by email for each project.
