There are a few situations that come up repeatedly, and most business owners recognize at least one of them when they hear it described.

The first is errors. Your bookkeeper or in-house accounting person is doing their best, but mistakes keep showing up. Bank reconciliations don’t tie out. Revenue is miscategorized. Payroll entries are posted incorrectly. You catch some of these yourself, but you shouldn’t have to. If you’re spending hours each month reviewing and correcting someone else’s work, that’s a sign you need a layer of oversight that doesn’t currently exist.

The second trigger is growth. Somewhere around $1M to $2M in annual revenue, the financial complexity of a business tends to outpace what a single bookkeeper can handle well. You might be adding employees, taking on larger contracts, dealing with multiple revenue streams, or managing vendor relationships that require tighter AP controls. The bookkeeper who was fine at $400K in revenue isn’t necessarily the right person to manage the books at $1.5M. That doesn’t mean you replace them. It means you add someone who can supervise the work and handle the higher-level reporting.

The third is external pressure. A bank asks for financial statements as part of a loan application. A potential investor wants to see clean books. You’re going through an audit. These situations demand a level of accuracy and presentation that goes beyond routine bookkeeping. An external controller can step in and make sure your financials are ready for outside scrutiny.

Then there’s owner burnout. You started the business to run the business, not to reconcile bank accounts at midnight. If financial review has become the thing you dread most each month, bringing in an experienced set of eyes frees you up to focus on what actually generates revenue.

The economics usually make sense. A full-time controller in New York City can cost $90,000 to $130,000 a year in salary alone before you add benefits and payroll taxes. An external controller working on a part-time basis costs a fraction of that because you’re only paying for the hours and oversight you actually need.

If any of these situations sound familiar, it’s probably worth having a conversation about what that arrangement would look like. At M&H Accounting Services, we provide small business bookkeeping in the Bronx and across all five boroughs, including controller-level oversight for businesses that have outgrown basic bookkeeping but aren’t ready for a full-time senior hire.
