Built on Real Experience, Focused on Your Success

We're not just number crunchers. We're business partners who understand what it takes to turn financial data into profitable decisions that actually work in the real world.

Why We Do This Work

Back in 2019, I spent three months helping a Plymouth manufacturing company figure out why their profits kept shrinking despite growing sales. Turned out, they were losing money on every third order but didn't know which ones. That's when I realized most businesses are flying blind with their numbers.

Honest Analysis: We tell you what the numbers really mean, not what you want to hear
Practical Solutions: Every recommendation comes with clear steps you can actually implement
Real Partnership: We work alongside your team, not from some distant ivory tower
Long-term Thinking: Quick fixes rarely last – we focus on sustainable profitability

The People Behind the Numbers

pentarivolum started because I got tired of seeing good businesses struggle with basic profitability questions. After years in corporate finance, I knew there had to be a better way to help smaller companies access the same level of financial insight that big corporations take for granted.

How We Actually Work With You

No cookie-cutter approaches here. Every business has unique challenges, and our process adapts to what you actually need rather than what looks good in a presentation.

Understanding Your Reality

We start by spending time in your business – not just looking at spreadsheets, but understanding how decisions actually get made, where the pressure points are, and what keeps you up at night. This isn't a one-hour phone call; it's proper discovery work.

Finding What Matters Most

Not every number deserves equal attention. We dig deep to identify the 3-5 key metrics that actually drive your profitability. Sometimes it's obvious, sometimes it's buried in data you've been collecting but not really using. Either way, we find it.

Building Systems That Stick

The best analysis is useless if it sits in a drawer. We work with your team to create monitoring systems and decision-making processes that become part of how you run the business. Simple, sustainable, and focused on what actually moves the needle.
