How M.A.S Works can help

M.A.S Works helps businesses work better. The right service depends on the problem, the size of the business and how much support is needed.

Map. Automate. Scale. is the method behind all four. Understand the current state, improve what is getting in the way, then make the changes part of how the business runs.

If you are unsure where you fit, an hour is usually enough to work it out.

Operational Business Improvement

For owners and MDs of businesses roughly £100k to £20m turnover who know the business could run better and want a clear view of what to fix first.

Over three months I work through seven areas of the business with you and your team, from customer acquisition and planning through to admin, compliance, retention and growth.

You finish with the important processes mapped, a clear picture of where your time is going and a prioritised 30/60/90 plan with named owners.

The aim is to remove avoidable pressure from the owner, close obvious gaps and make the business easier for the team to run.

02Owner-managed businesses · sale, succession or stepping back

Exit Ready Strategy

For owners thinking about selling, handing over or stepping back in the next three to five years, who want to know what a buyer will actually be looking at.

This is the 90-Day Operational Review run with the exit in mind. The same seven areas, read for a different question: how much of this business depends on you, and what would a buyer discount it for.

The work focuses on recurring revenue, customer concentration, financial clarity, owner dependency, documentation, compliance and future growth. You get a score at the start and updates as it moves.

Tax, legal and transaction advice stays with the specialists. My side is making the business work without you in it.

Project Delivery

For businesses that need experienced support on a live programme, project, change or interim requirement.

Support includes project and programme management, business analysis, HR and payroll cover, workshop facilitation, process improvement and M&A operational readiness. Work can be billed by the hour, day or scoped for a longer engagement.

Training and practical toolkits are also available where the business needs to build capability internally.

The aim is to give important work clear ownership and get it moving properly.

04Scaling mid-market · £10m to £100m

Fractional COO / CTrO

For scaling businesses between £10m and £100m that need experienced operational or transformation leadership without immediately appointing a full-time COO.

I work as a Fractional COO / CTrO for one to three days a week, joining the leadership team and taking ownership of the operational priorities or transformation work that need senior attention.

Work can start on a day rate and move to a monthly retainer if ongoing support is needed. The number of days is reviewed quarterly.

The aim is clearer ownership, better management routines and a leadership team that can run more of the business without everything returning to the CEO.
