What are internal controls in simple terms?

Internal controls are the checks and approval steps that make sure no single person can move money or change the books without someone else knowing about it. They range from separating who approves a bill from who pays it to requiring a second signature above a certain dollar amount.

We only have three employees. Can we really segregate duties?

Full segregation is difficult with a very small team, but compensating controls can close most of the gap. Common examples include having the owner personally review the bank statement each month or requiring dual approval on any payment above a set threshold.

Will an internal controls review disrupt our daily operations?

No, the assessment itself is done through interviews and a review of your current processes, and any changes we recommend are phased in on a timeline that fits your team. We do not require a pause in operations to complete the review.

Do lenders actually ask about internal controls?

Yes, lenders and bonding companies performing due diligence on a loan, line of credit, or bonding limit increase routinely ask about approval processes and segregation of duties as part of their risk assessment. Being able to describe a documented control environment strengthens your position in those conversations.

What sends contractors looking for this

One office manager writes the checks, records them, and reconciles the statement alone

It's common in a small trades shop for a single office manager to have full access to the bank account, write checks to vendors, run payroll, and reconcile the statement each month with nobody else looking at any of it. That's not a reflection of trust, it's a structural gap that exists no matter how reliable the person is.

Without a second set of eyes on cash, an honest coding mistake or a deliberate misappropriation can continue for a long time, since the same person entering the transaction is also the one checking whether it's correct.

Unsegregated duties around cash create real theft exposure, and shops that have discovered a loss this way have found it was often going on for a year or more before anyone noticed a pattern in the bank statement.

Supply house purchases go through with no one signing off

Techs and dispatch pick up materials on a company account at the supply house, and the bill just gets paid when it arrives, with nobody checking it against the job it was actually for. There's no written policy on who can charge the account or how much before someone has to approve it.

This makes it nearly impossible to catch a personal purchase run through the company account, or materials charged to one job that actually went to a side project, until the job cost report comes back wrong months later.

Without an approval step, unauthorized or misallocated supply house charges can run for months before anyone notices, and any bonding company or lender review will flag the missing approval trail as a real weakness.

We're worried about what a bank or bonding company will find if they look closely

As shops pursue a larger line of credit or a bonding limit increase to bid bigger commercial jobs, lenders and bonding companies increasingly ask about who controls cash and approves payments, not just what the financial statements say. A shop that can't describe its approval process raises a flag even when the numbers look fine.

Owners usually find this out only when the request comes in, leaving little time to put real controls in place before the review happens.

Weak or undocumented controls can delay a bonding limit increase or a line of credit renewal, and in some cases trigger a more invasive review than would otherwise have been required to get the same financing.

How we fix each of those

01
We separate duties wherever your team size allows
We map out who initiates, approves, and records each type of transaction, and we restructure responsibilities so no single person controls cash from start to finish. Where your team is too small for full separation, we set up the owner as the independent monthly reviewer of the bank statement.
02
We build a written approval policy for supply house and card purchases
We document specific dollar thresholds and required sign-offs for supply house purchases, company card use, and vendor payments, and we set that approval step up inside QuickBooks Online so every purchase above the threshold is tied to a job and a name before it gets paid.
03
We prepare your controls to hold up under a bank or bonding review
We document your control environment in a form a lender or bonding company can review directly, and we test it every quarter to confirm it's actually being followed, not just written down, before you're ever asked to produce it on short notice.

Everything included

Segregation of duties assessment across cash, payables, and payroll

Written approval policy with dollar thresholds for supply house purchases
Approval workflow setup inside QuickBooks Online

Brett Neal has been our family's accountant for over six years now, because he is the most dependable professional in this business. We started with Brett as two separate single-filers with simple W-2's and quickly graduated to a married couple having multiple types of complicated business/tax filings. Brett took every shift in stride; every transition has been carried out smoothly and without any hiccups. Trust that this is the guy for all your filing, bookkeeping, and financial consulting needs.
