AI back office · managed

You're already paying for AI. It still isn't doing your admin.

Subscriptions don't run a business — wiring does. Muffin & Co connects the AI you already pay for to the work you actually do: invoices, follow-ups, onboarding, accounts. Then we keep it running, so you don't have to.

Taking 3 founding clients. One workflow each. From £200/month — cancel monthly if it doesn't pay for itself.


The gap

The tools exist. The plumbing doesn't.

It's 11pm and you're doing invoices again — while three AI subscriptions sit on your card. ChatGPT can't see your job sheet. Claude doesn't know your accountant. The gap between "paying for AI" and "AI doing your admin" is setup, integration and maintenance — and that's a job nobody in a small business has time to hold.

01

The subscription trap

Small businesses now spend hundreds a month on AI tools that answer questions brilliantly — and never touch the spreadsheet, the invoices or the books.

02

The hidden cost

Five hours of admin a week at your billable rate is £6,000+ a year. Before the late invoices, the missed follow-ups and the evenings you didn't get back.

03

The missing role

What you need isn't another tool. It's someone who wires the tools into your business and owns the result. That's the role we play.


What we run

Your whole business lives in a spreadsheet. We make it run itself.

Jobs in. Invoices out. Accounts up to date. We take the spreadsheet you already run your business on and turn it into a back office that does its own admin — one workflow at a time.

Your spreadsheetjobs, clients, bookings — exactly as you keep it today
The engineAI drafts invoices, follow-ups and documents — checked by rules, never guesswork
Your systemsdrafts land in Xero, your inbox, your templates — you press approve
Flow 01

Job sheet → invoices → Xero

Completed jobs become client invoices, contractor statements and referral bills — as drafts in your accounting system, ready to approve.

Flow 02

Enquiry → quote → follow-up

New enquiries get a same-day quote and a polite chase three days later. Nothing falls through the cracks because nothing relies on memory.

Flow 03

New client → onboarding pack

The right forms, contracts and welcome information go out automatically the moment a client says yes — consistent every time.

Currently deploying our first managed back office for a London chauffeur company — job sheet to invoices to Xero.


Managed, with guardrails

No dashboards. No "AI transformation". Your admin, done.

We're not an agency selling you a platform. We build one workflow that works, run it for you, monitor it, fix it — and only then build the next one. And because the work is sensitive, the system is built so it can't embarrass you:

You keep the approve button. The system creates drafts. A human — you — sends them. Nothing reaches a client without your sign-off.

Your accountant's process is untouched. We feed clean drafts into the system they already use. Reconciliation stays exactly where it is.

Every run reports itself. What was created, what was skipped and why. No silent failures, no mystery output.

Cancel monthly. If the back office doesn't visibly pay for itself, stop paying for it. We keep the bar exactly that high.


Pricing

The assistant you can't afford costs £200 a month.

A part-time admin needs hiring, training and managing. A pile of AI subscriptions needs you to do the wiring. A managed back office just runs.

OptionMonthly costWho does the work
Part-time admin assistant£900+Them — once hired, trained and managed by you

One-off setup fee per workflow, quoted on the founding call. Monthly fee covers running, monitoring and fixes. No long contract — the work earns the renewal.


Founding clients

Three slots. One workflow each.

We're taking three founding clients while we build in the open. You get founder-level attention and founding pricing, locked in. We get a case study. Twenty minutes: bring the spreadsheet you run your business on, and we'll tell you exactly what it could do on its own.
