External Controller

A second set of eyes and a layer of oversight on top of your existing accounting. We review the work, tighten reporting, and add controller-level rigor, so you get more confidence in your numbers without adding a full-time hire.

What This Is

External controller services add a layer of professional oversight to the accounting you already have in place. If you have a bookkeeper or an in-house accounting person handling the day-to-day work, this service puts a second set of eyes on their output to verify that the numbers are accurate, the processes are sound, and the reporting tells you what you actually need to know.

This is not about replacing your existing team. It is about adding the controller-level review that a larger company would have built in. You get professional-grade oversight without hiring a full-time controller, which most owner-operated businesses do not need and cannot justify.

Review and Verification

We review the work your bookkeeper or accounting staff has done. We check reconciliations, verify that transactions are categorized correctly, and confirm that the financial statements are accurate and complete before you rely on them for decisions.

Who This Fits

This service is for businesses that have outgrown doing their own books but have not yet reached the size where a full-time controller makes sense. You have someone handling the transactions. You need someone checking the work.

The Gap

Day-to-day bookkeeping keeps the transactions moving. But without someone reviewing that work, errors can compound month after month. A miscategorized expense here, an unreconciled account there. Small issues turn into reporting problems that affect your decisions and your tax filings.

Most bookkeepers are good at entering data and keeping things current. Fewer are trained to step back and ask whether the numbers make sense, whether the processes create risk, or whether the reports actually give you what you need to run the business. That is the gap an outsourced controller fills.

Catching Errors Early

Mistakes happen. The question is how long they go unnoticed. With controller-level review, problems get caught before they snowball. You find the duplicate entry before it throws off your profit margins. You catch the missing reconciliation before year-end.

Confidence in the Numbers

When you look at your financial statements, you should be able to trust them. External controller oversight means someone with real accounting depth has verified that what you are looking at reflects reality. You stop wondering if the numbers are right.

What Changes

With an external controller in place, you get tighter reporting and better controls. The monthly close becomes more rigorous. The financial statements come with the confidence that a CPA has reviewed them. You know the books are ready for your tax preparer, your banker, or anyone else who needs to see them.

Simona brings CPA-level review to your existing accounting process. She looks at the work your team is doing, identifies where things could be tighter, and adds the layer of oversight that keeps the whole system honest. You get the benefit of controller-level rigor on a scope that fits your business.

Tighter Controls

We look at your processes and identify where controls are weak. How expenses get approved. How bank accounts get reconciled. How journal entries get documented. Better controls mean fewer surprises and a cleaner audit trail if you ever need one.

Better Reporting

Financial statements should tell you something useful. We work with you to make sure the reports you get actually answer the questions you have about your business. That might mean restructuring how costs are tracked or adding new views into the data.
