Billing a client's AI to them
Give one client their own Claude key so their AI usage is billed directly to their Anthropic account.
Some clients want their AI usage on their own bill — either because they already have an Anthropic account, or because they'd rather pay the model provider directly than have it marked up.
You can give any single workspace its own Claude API key. Everything in that client's workspace then runs on their key and appears on their Anthropic invoice. Every other client carries on using yours.
How keys are chosen
When one of your products runs, Productised picks a key in this order:
The workspace's own key
If this client has their own key set, it's used — and Anthropic bills them directly.
Your account key
Otherwise the key on your account is used, so it covers every client by default. Set it once, not once per workspace.
Productised credits
If there's no key anywhere, the product runs on the platform's own key and draws from your plan's credit allowance.
Setting a client's key
Switch into that client's workspace, then go to Settings → Claude API Key. You'll see two cards: your account key, and one for the workspace you're in.
Paste the client's key into the workspace card and save. To undo it, choose Remove, use account key — the client goes back to running on yours.
How keys are stored
Keys are encrypted before they're stored and are never shown again in full. Once saved, the page shows only a masked version like sk-ant-…4f2a, so you can confirm which key is set without the key itself being sent back to your browser.
If you need the original value later, get it from the Anthropic Console — Productised can't show it to you.
sk-ant- is rejected when you save it. That's deliberate: a mistyped key would otherwise be stored happily and every run would quietly fall back to your credits while you believed the client was being billed.What it doesn't change
Giving a client their own key changes who pays Anthropic for running the products. It doesn't change your Productised subscription, your plan's product limits, or your Brain allowance — those stay with your account.
