For finance teams · Immiscible docs

This page is for whoever looks after the money. Nothing on it needs an engineer, and nothing on it is code. If someone else will connect your agents, there is a button for inviting them along the way.

#What you are setting up

Three things, in the order most finance teams want them.

See what you spend. One usage file from OpenAI or Anthropic is enough to see last month’s AI spend by model and by team, and which keys nobody is watching. If you only want this, the AI check does it without an account.

See what you could save. The same check prices what cheaper models doing the same kind of work, and caching, would have cost. Those figures are estimates and say so: we never see your prompts, so each is the most it could be, and the report shows how it was worked out. Once your engineer sends model traffic through the gateway, the estimate becomes a measured figure.

Decide what agents may spend. Give each team a monthly budget. When an agent wants to pay for something, it asks first: inside your rules it goes ahead; above your line, or to a supplier nobody has paid before, a person decides. Everything is written down in a record nobody can quietly change.

Go to https://immiscible.fly.dev/signup. You can sign up with Google, with Microsoft, or with an email address and a password. Every new workspace starts with thirty days of Business, with no card. After that it stays free, with 3 governed agents and up to 5 people, and nothing is deleted.

#2. See the example

The first screen shows a request Immiscible would hold for you: a team about to run a long batch on the most expensive model, close to its monthly AI budget, when a cheaper model can do the same work. Choose Use the cheaper model or Let it run to see what each does. It is an example: nothing is spent and nothing is recorded. You can see it again later from Overview.

#3. Four short questions

Setup is four steps, one decision each. Every step can be skipped, and anything you skip waits on Overview, ready when you are.

Step	What it asks	What to know
Run the AI check	A usage file, or the person who holds the admin key	Download last month’s usage from OpenAI or Anthropic and drop it in; the step shows you where to find it. Or we send the key holder a one-page link that lasts 14 days. The key can read the bill and nothing else. You see what you spent, what you could save and which keys nobody is watching, and Overview links to the newest report.
Where requests reach you	Slack, Microsoft Teams or email	With Slack you approve or deny in the message itself. Teams needs whoever runs it for you; we send them a short guide. Email always works.
Who else approves	Their email addresses	Approvers answer requests and change nothing else. They are free on every plan.
Turn on protection	Two rules, already written	Payments above an amount you choose need a person, and so does any supplier you have not paid before; each team also gets a monthly AI budget. The step lists what those rules would have held, including what your uploaded usage says about the budget, then you choose Turn on protection or Keep watching only.

Keep watching only means nothing is blocked yet: Immiscible records what it would have done, so you can see it working before it holds anything up.

#4. Approve your first real request

When an agent asks for something above your line, you hear about it where you chose in setup. Each request says who is asking, how much, to whom, and why it came to you. Approve lets that one payment through; Deny stops it, and the agent is told why. Above a set amount, approving asks you to confirm it is really you, with a passkey or a code from your authenticator app.

The console works on a phone too: open it in your phone’s browser and add it to your home screen to get notifications.

#Where things are

Rules	Your company rules: what any agent may do on its own
Records	Everything an agent asked to do, what was decided, by whom, and the signed proof
Settings	People, billing, sign-in, and Connections for Slack, Teams, accounting and reporting tools

#Things finance teams usually ask

Are the savings real? They are estimates until traffic goes through the gateway, and the report says so beside each figure. It prices the tokens you were billed for at a cheaper model’s rates; it cannot see your prompts, so it cannot know whether the cheaper model would have done every task as well. In shadow mode the gateway records what it would have routed and at what price, which turns the estimate into a measured figure without changing anything.

Does Immiscible hold our money? No. It never holds funds, card numbers or wallet keys. It says yes or no; your card, bank or wallet moves the money.

What does it cost? We charge for the agents we govern, not for people: approvers, finance and auditors are free. Free covers 3 governed agents. Team is £39 a month, billed yearly, with 10 agents; Business is £499 a month, billed yearly, with 100 agents, SCIM and ten years of records. It never takes a share of what your agents or models spend. See pricing.

Can I stop an agent straight away? Yes. Open Agents, choose the agent, then Stop. From that moment it can do nothing until someone you trust starts it again. See the kill switch.

What do I give our auditors? Settings, Export for your auditor: a signed bundle of the records they ask for, which they can check without an account and without trusting us. See evidence.

Can it reach our accounting tools? Under Settings, Connections: monthly journals to Xero and QuickBooks, every agent card charge matched to its approval in Ramp, and spend sent to Google Sheets or a board link.

Who connects the agents? Your engineer. In setup or on Overview, choose Invite them; they get a page of their own with everything they need, and the quickstart takes them about five minutes.
