Your books are months behind. A few weeks from now, they won’t be.
I’m a certified public accountant for small businesses, hired by the project — not on a retainer. I catch up the backlog, fix the errors nobody could find, get you through the audit. Then I hand everything back organized, and leave.
Trained at one of the world’s four largest accounting firms. You work with me directly. Nothing to buy but the fix.

order, restored month by month
That’s the honest anatomy of most accounting problems. The 10% is workable. Let’s take the 90% off first.
Sound familiar?
You’re not running a bad business. You’re running a busy one.
The backlog
The books are months behind. Not because anyone failed — because every week the business came first, and the pile grew quietly behind it.
The “basics” ceiling
Your bookkeeper keeps the daily entries moving. But the complex thing — the error nobody can find, the accounts that won’t reconcile — sits untouched, because it’s nobody’s job.
The thing that’s coming
An audit. New software. Real growth. Something is arriving that your current setup can’t carry, and you know it before anyone says it.
None of these fix themselves. They compound — every month behind makes the next decision a guess: pricing, hiring, that investor meeting. And guessing is the expensive part.
It’s not you — the usual fixes are built wrong. The software that promised clarity added a subscription and more admin. A full-time hire for a three-month problem makes no sense. And the big firms are priced for corporations, not for you. Books that fell behind aren’t a crisis. They’re a project — and projects end.
Who this is for
Owners of small and mid-size businesses whose books stopped keeping up.
Your accountant is at capacity, or your bookkeeper handles the basics and the complex thing sits untouched — and something is coming that the current setup can’t carry. If that sounds like your desk, this page was written for you. Works in English and Spanish, anywhere in the US.
What I do
One accountant. Three ways in — and what actually happens in each.
Catch-Up & Clean-Up
For you if the books are months behind — or “caught up” on paper, but nothing reconciles.
What I do
- Go month by month and close each one properly — no skipping ahead.
- Reconcile every bank, card and loan account until the numbers agree with reality.
- Find the entries that made the numbers wrong, fix them, and show you where they came from.
- Write down what changed, so your bookkeeper can keep it that way.
You get back
Books that are current and correct — plus a short walkthrough of what was wrong, in plain words.
Special Projects
For you if an audit is coming, a balance won’t reconcile, or you’re moving to new accounting software.
What I do
- Prepare the audit file and stand as the auditors’ single point of contact, so nobody on your team has to.
- Untangle the complex entries — balances between companies, the adjustments nobody dared to post.
- Set up new accounting software correctly and move clean data into it.
- Train your team on the new setup until the logic is theirs.
You get back
The one-time job done right — without pulling your people off their daily work.
Growth-Ready Setup
For you if you’re opening locations, bringing in investors, or growing faster than the back office.
What I do
- Design the month-end close: reconciliations, checklists, a rhythm that holds.
- Build the reports owners and investors actually read — and trust.
- Set up the accounting for new entities or locations before they open, not after.
- Hand the whole process to your team with walkthroughs — then step away.
You get back
An accounting system that carries growth instead of collapsing under it.
Not sure which way is yours? That’s what the call is for.
A recent project
Five locations. Five months of broken closes. One audit on the calendar.
Most of my projects are smaller than this one — it simply shows the whole range of the work.
+ 1 international entity

new bookkeepers, manager leaving
about to open
Before
Investors waiting on numbers nobody trusted. Balances tangled between companies. The finance director carrying it alone.
What I did
Cleaned the books first. Rebuilt the month-end with reconciliations and checklists. Trained the new team and the incoming manager. Single point of contact for the auditors.
After
Audit closed with minimal findings. A clean slate for the finance director — and a system that runs without me.
Read the full story
A restaurant group — five locations across the country and one international entity — hit everything at once: new accounting software, a brand-new bookkeeping team, their accounting manager leaving, and two more locations about to open. Five months of broken closes. Tangled balances between companies. Investors waiting on numbers nobody trusted, and a year-end audit on the calendar. The finance director was carrying it alone, and it was too much for one person.
I stepped in and took it apart systematically. Books first: cleaned up, year-end figures accurate. Then the process: reconciliations, checklists, walkthrough meetings with the bookkeepers until the logic was theirs — I trained the new team and the incoming accounting manager. Along the way: the complex entries, the two openings, the budget talks. And through year end, I was the auditors’ single point of contact.
The audit closed with minimal findings. The finance director got back a clean slate and a system that runs without me.
The mess was never the real problem. The missing system was.
The call
What happens if you book.
30 minutes, by video
One link, one click — no account, no installation. Camera on or off, as you like.
Nothing to prepare
No documents, no reports, no numbers. You simply explain the situation in your own words — I ask the questions.
An honest assessment — either way
If I’m not the right fit for your situation, I’ll tell you in the call, and you still leave with next steps.
How it works
Three steps. Most of them mine.
Tell me the situation
A 30-minute call. Bring nothing but honesty — the mess is normal here.
I do the untangling
You run your business. I collect every question into one efficient meeting — not daily interruptions.
You take it back — organized
Clean books, a system you understand, and no dependency on me afterward.
Then it’s a Tuesday morning, the numbers are just there, and you make the decision in ten minutes instead of carrying it for a month.
About
Why I work this way.
I trained at one of the world’s four largest accounting firms — where I learned exactly how good accounting is done, and watched it priced out of reach of the businesses that need it most. So I left to do the same work the simple way: one client at a time, by the project, done properly, handed back.
Working with me means working with me. I’m the owner and the only employee. I ask the questions your books can’t answer on their own, and I treat your numbers like my own name is on them — because it is.
The firm is named for Mercury — messenger of the gods, patron of clear and swift communication. That’s the standard for every email, every meeting, every handover.

FAQ
Fair questions.
How do I know I can trust you with sensitive financials?
Fair question — it’s your business’s bloodstream. I’m a licensed certified public accountant, bound by professional confidentiality standards that carry real consequences, not just promises. Everything you share stays between us. And the first call costs you nothing but 30 minutes — judge me there.
What does the call cost?
Nothing. The call is where we both see whether this fits — I don’t sell anything in it. If it’s not a match, you still leave with next steps.
How do you charge?
By the hour, for the duration of the project — no retainer, no subscription, nothing that keeps billing after the work is done. You get an estimate after the first call, when I’ve actually seen the situation. I don’t quote what I haven’t seen. For a project of a few weeks, that’s a fraction of what a full-time hire or a big-firm engagement would cost you.
Can you work with our existing bookkeeper and software?
Yes — that’s the normal case. I fix, document, and hand back. I don’t replace your bookkeeper, and I sell no software, so there’s no side agenda in my advice.
Do you work remotely?
Yes. I’m licensed in Florida and work with clients across the US. Most projects run fully remote — your books don’t care where the desk is.
Do you do taxes?
No — on purpose. I stay in my lane: catching up books, fixing errors, audits, systems. If you have a tax preparer, I make their job easier: clean books are the best tax preparation there is.
How long does a typical project take?
It depends on the depth of the mess — honestly. Catch-ups usually run a few weeks; audit prep is scoped by its deadline. You’ll have a timeline after the first call, and I only take projects I can give full attention.
We’re “caught up” — but it still feels messy. Is that a real problem?
Yes, and it’s the most common one I see. Current isn’t the same as correct, and correct isn’t the same as clear. If you can’t read your own financial position from your books, they’re not done serving you.
Won’t AI tools just handle this soon?
AI is genuinely good at the routine entries — and it makes confident mistakes. Untangling those is exactly the work I do. The tools will get better; the need for someone who knows what “correct” looks like doesn’t go away.
Bring me the mess. Leave with a plan.
One call. You talk, I ask, and you leave with next steps — whether we work together or not.
