Built by People Who’ve Actually Run Plumbing Businesses
We’re not just bookkeepers—we’ve been in your shoes, managed real operations, and understand exactly where money gets lost in service businesses.
I’m Marvan Davis, and I didn’t start in bookkeeping. I started in the field.
After serving 13 years in the United States Marine Corps, I went on to build multiple plumbing and water treatment businesses from the ground up. Fidelis Elite Systems grew to $28M in revenue, and Fidelis Plumbing reached over $12M.
Over the years, I saw the same problem again and again—both in my own companies and in others: the numbers were always behind, unclear, or unreliable.
Not because business owners didn’t care—but because they didn’t have a system that actually gave them real visibility into what was going on.
That’s why we started Fidelis Ledger.
We built this to give plumbing business owners what I wish I had earlier—clear, accurate financials, real visibility into cash flow, and a system that helps you make confident, informed decisions.
Because when you understand your numbers, you run a better business.

What Business Owners Are Saying
What a difference it is to have clean accounting records. My books are perfect! Thanks Fidelis Ledger.
Myles Holt
Service Business Owner
My books were a mess with transactions going into the wrong categories, and it made it impossible to understand my numbers. Fidelis Ledger cleaned everything up and showed me the category creep that had been building over time. Now my reports actually make sense and I’m able to make better decisions financially.

Fidelis Ledger is so much more than bookkeeping. The reports they generate for their clients are so insightful. I’ve had an excellent experience working with this bookkeeping company. Their team is highly professional, responsive, and extremely detail-oriented. I highly recommend their services to any business looking for trustworthy and efficient bookkeeping support.
