A fractional Chief Automation Officer for your business
Senior automation ownership, part-time. We set the strategy, build the automations and stay on to run them — a few days a month, on a flat retainer, no full-time hire required.
Automation matters to you. It's just not a full-time job yet.
Most UK SMEs are caught in the middle. Automation is too important to ignore — the businesses that do it well compound an efficiency advantage. But it's rarely a clean full-time role until you're fairly large, so the options are all bad: a project that decays once it ends, a £100k hire you can't yet justify or fully use, or an hourly agency that profits from things taking longer. The fractional CAO is the missing middle.
- Projects that decay — A one-off build ships and ends. Tools change, processes evolve, things break — and with nobody owning them, the automations quietly rot and the team drifts back to manual.
- A hire you can't justify — A good automation leader is £80k–£120k+ fully loaded, hard to recruit, and under-utilised in a smaller business where there isn't full-time work to fill their week.
- Hourly agencies — Unpredictable cost and misaligned incentives — the longer it takes, the more they earn. You want someone who owns the outcome, not the hours.
We own the automation function. You own the business.
A fractional CAO is the automation equivalent of a fractional CFO. You get senior judgement and ownership for the days a month you actually need it — setting strategy, building, maintaining and improving — on a flat retainer with aligned incentives.
- Independent — no commissions — We don't resell software or take platform commissions, so every recommendation is in your interest, not ours — including telling you when not to automate.
- Flat retainer, never hourly — A predictable monthly fee scoped to the quarter's priorities. No meter running, no incentive for work to drag. We're paid to make automation work, not to bill hours.
- Your team, levelled up — We build alongside your people and document everything, so capability stays in the business. The goal is a system your team can run — not dependence on us.
The whole automation function, owned
Strategy, building and ongoing care — at a few days a month rather than full-time.
Start small. Scale into a retainer.
No long lock-in, no hourly billing. You see the value before you commit to the ongoing relationship.
The low-risk way in. We map your processes, find the highest-ROI automation opportunities, and give you a costed plan. Use it to take the plan in-house, or as the foundation for what follows.
We build the first wave of automations — the ones that pay back fastest — at a flat project fee. You get working automation and a sense of how we operate before any ongoing commitment.
Once there's an ongoing automation function worth owning, we move to a flat monthly retainer — typically 2–3 senior days a month — covering strategy, building, maintenance and improvement, scoped each quarter.
Every quarter we review impact and reset priorities. Scale the retainer up or down, pause it, or hand over to an in-house hire when the time comes. Your call, always.
What a fractional Chief Automation Officer is
A fractional Chief Automation Officer (CAO) is a senior automation leader who owns your automation function part-time, on a retainer — typically a few days a month. They do what a full-time head of automation would: set the strategy for what to automate and in what order, build or oversee the builds, maintain what's live, and continuously improve it as the business changes.
It's the same model you already understand from the fractional CFO or fractional CTO: senior capability and genuine ownership, without a full-time executive salary or the risk and delay of recruiting one. For the conceptual deep-dive — the role, where it came from, how it compares to the alternatives — see our guide, what is a fractional Chief Automation Officer. This page is the service itself.
Why the model exists
Automation has an awkward shape for most SMEs. It's too important to ignore, but rarely a clean full-time job until you're fairly large. That leaves three poor options — a project that decays once it ends, a full-time hire you can't yet justify or fully use, or an hourly agency whose incentives pull against yours. The fractional CAO is the missing middle: ongoing senior ownership, predictable cost, aligned incentives, no permanent hire. We make the full argument in our automation as a service guide.
What you actually get
Across a typical month, a fractional CAO engagement covers:
- Strategy — continuously identifying where time and money leak and deciding the next automation to build, with a business case. The most valuable part, and the hardest to hire for.
- Building — hands-on delivery across finance, marketing, AI and operations, using the lightest durable tool.
- Maintenance — keeping live automations working as tools and processes change, so they don't decay.
- Measurement — tracking what each automation saves or earns and reporting it.
- Advice — independent guidance on tooling and on where AI genuinely helps versus where a rule wins.
- Capability transfer — building alongside your team and documenting, so the knowledge stays with you.
It's the whole function, owned, at a few days a month.
What it costs — and how it compares
The fractional CAO retainer is £5k–£15k per month, typically 2–3 senior days a month, scoped to the quarter's priorities. Compare the realistic options for a growing UK SME:
- Full-time head of automation: ~£80k–£120k+ fully loaded, plus recruitment time and risk, plus management overhead — and often under-utilised below a certain scale.
- Hourly agency: unpredictable, and structurally incentivised to take longer.
- Fractional CAO retainer: predictable monthly cost, senior capability, aligned incentives, no recruitment risk, and broad experience across many businesses' stacks.
For most SMEs the retainer wins until automation is genuinely a constant, full-time job. We bill a flat retainer, never hourly, and take no platform commissions.
How you start
You don't sign up to a retainer cold. The usual path:
- £1,500 Discovery Sprint — a one-week paid scoping exercise that maps your processes and gives you a costed plan. Low-risk, and yours to take in-house if you want.
- A fixed-fee foundational build — the first wave of automations, at a flat project fee, so you see working results and how we operate.
- The fractional CAO retainer — once there's an ongoing function worth owning.
No long lock-in. We review quarterly and you scale up, down, pause, or hand over to an in-house hire whenever it's right.
When a fractional CAO isn't right
We'll tell you honestly in discovery:
- If you have one finite automation need, a fixed-price project is more honest and cheaper than a retainer.
- If automation is genuinely a full-time job already, hire in-house — ideally after a fractional CAO has built the foundations, so your hire inherits a working system.
- Below ~£1m turnover, the economics rarely work; a one-off project or a good bookkeeper usually beats a retainer.
How this fits with the wider Watermelon model
The fractional CAO is our core offering — the ongoing form of everything else we do. The Discovery Sprint is the entry point; automation consulting is the project work; the automations, functions and industries pages are what gets built; and the guides explain the thinking. The fractional CAO is the person who owns all of it for you.
