Getting a permission in writing from a supplier
Where a supplier's pages say nothing about a point, the cheapest fix is to ask. A short message produces a dated sentence, and a dated sentence is what a client review wants and a silence can never be. As of 2026-09-12.
| Ask | Useful answer |
|---|---|
| Which plan permits commercial use of the output | A plan name, in a reply you can keep |
| Whether output made earlier stays usable | A yes or no, with any condition stated |
| Whether uploads are used for training | A statement, and whether it holds on this plan |
| Whether an indemnity is available | A yes, a no, or the terms it would sit in |
Inclusion rule. Questions that a supplier can answer from its own documents, and that a register reading public pages cannot answer for you. Order. From the question most often unanswered to the one most often negotiated.
1Ask about a document, not about your campaign
A supplier's support desk can tell you what its terms say and cannot tell you whether your particular use is lawful. Asking the second question produces a careful non-answer and burns the exchange.
Framing matters more than length. Which plan grants commercial use of the output gets a plan name. Can we run this in a campaign gets a paragraph about consulting your own advisers.
2Keep the reply the way you would keep a clause
The date, the wording, and who said it. A reply from a named person at a supplier is evidence that a reasonable decision was made at a moment, which is the same job a dated reading does in a register.
Where the answer contradicts a public page, keep both. The contradiction is usually a drafting lag rather than a trap, and it is worth knowing which version a supplier's own staff believe.
3What an unanswered question tells you
Sometimes a supplier cannot answer because the position does not exist yet. That is useful information about how much of its offering is settled, and it is a reason to keep the question open rather than to assume the favourable reading.
A supplier that answers quickly and in writing is also telling you something about what an escalation will look like later. That is not a licence fact, and it belongs in the same file.
4Where the vendor statements are kept
The mechanics above apply to anyone. What a given vendor has committed to in writing is held on the register instead, each line with the plan page it came from and the date it was checked.
An explainer, not an entry in the register. Vendor statements are held, with their sources, on commercial use, and nothing on this page is legal advice. Related: A supplier file, Which account.

Alongside the terms behind “Asking for a sentence”, SceneMixer's guides describe the work itself this way:
The terms grant you the output to the extent the law allows, and that includes commercial use.
