How it works

Brief the team once. Ask anything after that.

No forms, no briefs, no booking. You talk to Greymill the way you would talk to a colleague who already knows your business.

01

Tell them about your business, once

Your industry, where you operate, the size of the team and what matters right now. Everything the sixteen specialists produce from then on is framed for your business, not a generic one.

Why you can trust it

Knows your numbers. Knows your trade. Keeps it private.

Three things that make an answer worth trusting. Greymill does all three, every time.

xeroqb
Knows your numbers

It reads your real numbers, so you never start from scratch.

Your books, your inbox and your website, read-only. It remembers what you have told it. Ask about October and you get October’s numbers, not a form to fill in.

Over 140,000 words written about trades like yours.

Forty-plus kinds of business, each with its own prices, rules, busy seasons and paperwork. UK and US law, tax and hiring rules where they are different. Not a guess off the internet.

Partners and referrals

Two ways to share Greymill.

Two separate programmes. Partners who introduce clients are paid in cash. Customers who tell a friend earn credit on their own Greymill bill.

Partner programme

Cash, tracked to the pound

For franchise head offices, trade associations and business networks, coaches and consultants, and IT, web and marketing agencies who introduce clients to Greymill.

  1. 1You share your link
  2. 2Your client joins, tracked to you
  3. 3They stay 60 days
  4. 4You are paid 30%, once

Paid once: 30% of the client’s monthly plan price, and only after 60 days, so a monthly client who cancels, or any client refunded, before then earns nothing.

Partners get their own dashboard: every click, trial and payment, live.

30% of the client’s monthly plan price, paid once 60 days after their first payment (annual plans are paid up front, so they qualify unless refunded). If they move to a cheaper plan before day 60, it is worked out on that plan; an upgrade keeps the plan they started on. Full terms in the Partner Agreement.

Refer a friend

Credit, inside the app

For Greymill customers on a paid plan. Your friend saves on their first month and you earn credit on your own bill.

How it adds up, on any paid plan:

  • Refer 1 friendBill credit worth 40% of your monthly plan
  • Refer 3 friendsCredits add up: a free month, then more off
  • Your friend40% off their first month

Each friend earns you credit worth 40% of your own plan; credits add up.

Earned when your friend makes their first payment; shown in your own app.

Bill credit of 40% of your monthly plan price for each friend who pays, taken off your next bills automatically; it is not cash. Your friend gets 40% off their first month (on an annual plan, 40% of one month off their first year). Full rules in the Terms of Service.

Connections

Connect what you already run your business on. The team reads it, so you never have to explain.

Your books, your inbox and your website, read-only. A couple of minutes to connect, nothing is ever written back, and you can disconnect at any time.

The question everyone asks

Why not just use ChatGPT?

Because a chatbot has never seen your business. Greymill has. Same question, typed into both.

You type

“How is my cash looking for October?”

A general chatbot, like ChatGPT
✗ Can’t see your books, your inbox or your contracts. Asks you to type it all in.

The savings tracker

Software that shows what you save.

Most subscriptions ask you to trust they are worth it. Greymill values every conversation against the market rate for that category of work and shows you the running total.

Questions

Fair questions, straight answers.

Does Greymill replace my accountant, solicitor or other professional advisers?+
No, and it is not trying to. Greymill gives you a whole team to think with every day: the numbers modelled, the contract read, the campaign planned, the hire prepared, the filing checklist ready, all before you speak to anyone by the hour. What it produces is software output from the information you give it, so it takes no instruction, owes no professional duty and files nothing on your behalf. Where a matter needs a regulated professional to sign it off, Greymill says so and tells you exactly what to take to them. Customers arrive at their accountant or lawyer with the work done and the questions sharp, which is usually the cheapest hour they will ever buy.
Who is Greymill for?+
Owner-run businesses and small teams, typically one to fifty people, who have questions every week that would otherwise mean booking someone by the hour or going without. Trades, agencies, clinics, shops, consultancies, ecommerce brands, software companies: the specialists carry over 140,000 words of written industry knowledge across more than forty sectors and adapt to the one you tell them you are in. It is also for the people who have always wanted to start something and are not ready to quit the job or hire a team yet: Greymill gives you the finance, legal, marketing and operations thinking to test the idea properly, evenings and weekends, for the price of a few coffees a month.
How is the savings figure calculated?+
Two numbers multiplied together. First, the working time the output saved you, from a stepped model based on its length and capped so long outputs cannot inflate the total. Second, the typical market cost in your region of buying that category of work in. The full method is published and every weekly report links to it. It is an estimate, and it is deliberately built to under-claim rather than over-claim.
What happens after the 7-day trial?+
Your trial runs on the Scale plan so you see everything. If you do nothing, it simply ends. You are only charged if you choose a plan, and you can cancel any plan at any time from your account in two clicks.
Do the specialists talk to each other?+
Yes, inside your workspace and nowhere else. Greymill keeps one shared memory of your business so you explain things once: mention a specialist by name and they join with full context, and ask LEO a contract question and MAYA can weigh in on the numbers without you repeating a word. Nothing leaves your workspace. It is not shared with other customers, not used to train models, and you can read, edit or delete what the team remembers at any time. The memory compounds, so the team gets more useful every week you use it.
Is my business data used to train AI models?+
No. Your conversations belong to your workspace. They are not used to train models and they are not visible to other customers. Greymill Limited is registered with the UK Information Commissioner’s Office and the full detail is in the privacy policy and on the security page.
Do the specialists understand my country and industry?+
Greymill works globally, with deep coverage of UK and US rules where they matter, and over 140,000 words of industry knowledge across more than forty sectors from construction to ecommerce. Tell any specialist what you do and where, and answers are framed for your situation. Prices are shown in your local currency and checkout handles local tax.
Can my team use it too?+
Yes. Every plan is one workspace with one shared memory, and you can add team members from £75/mo each. Everyone on the account works with the same specialists and the same context, so a question answered for one person is answered for the business.
Do you have a partner programme?+
Yes, for franchise head offices, trade associations and business networks, coaches and consultants, and IT, web and marketing agencies who introduce clients to Greymill. You are paid 30% of the client’s monthly plan price, once, when the client is still with Greymill 60 days after their first payment (annual plans are paid up front, so they qualify unless refunded). If they move to a cheaper plan before day 60, it is worked out on that plan; an upgrade keeps the plan they started on. A monthly client who cancels, or any client refunded, before day 60 earns nothing. Partners get their own dashboard with every click, trial and payment, live, and are paid by bank transfer through Wise. Apply on the partner page; the terms are in the Partner Agreement.
Can I refer a friend?+
Yes, once you are on a paid plan: your link is in Settings in the app. Your friend gets 40% off their first month (on an annual plan, 40% of one month off their first year). When they make their first payment, you get bill credit worth 40% of your own monthly plan. Credits add up and come off your next bills automatically. It is credit on your Greymill bill, not cash, and it is separate from the partner programme. The full rules are in the Terms of Service.
What does Greymill not do?+
It produces the thinking and the documents; you stay in control of every action. Every connection is read-only. Whatever you connect, your books, your inbox or your website data, the specialists read it so they answer with real figures, but Greymill never writes to your books, never sends an email on your behalf, never makes a payment and never takes an action in another system. It also will not pretend to certainty it does not have: where a question turns on facts it cannot see or on a regulated judgement, it says so and tells you what to check.
How do I cancel?+
From your account settings, in two clicks, at any time. There are no lock-ins and no minimum term. Annual plans are refundable in line with the refund policy.

The team your business has been missing.
