Outsourced controller services

The controller reviews and signs off on the monthly close before it reaches you, which means checking the work rather than only producing it. They own the chart of accounts and the account-coding standards that keep categorization consistent month over month, so a report from six months ago and a report from this month actually mean the same thing when compared side by side. Internal controls, approval limits by spend level, segregation of duties between initiating and approving a payment, and periodic access review, get enforced as an ongoing part of the cycle, not documented once during onboarding and forgotten. Each month produces a short controller's memo flagging anything material or unusual that a reader would want to know about before it becomes a bigger problem. The controller also coordinates directly with your outside tax preparer and, where one is engaged, your independent auditor, handing over a ledger that has already been reviewed rather than one that needs to be untangled first.

Onboarding starts with a review of who currently has financial system access, what approval limits, if any, exist today, and how the chart of accounts is currently structured. We set a monthly review calendar: bookkeeping or ledger maintenance closes by a fixed date, the controller reviews and either signs off or flags issues within a set number of business days after that, and the controller's memo goes out alongside the close. Where issues get flagged, they get resolved and documented before the period is considered closed, not carried forward silently. Internal controls, once set, get spot-checked on a rotation rather than assumed to still be working; an approval limit that made sense at one spending level gets revisited as the business grows past it. The level of controller involvement is scoped at onboarding based on entity count and transaction volume, and gets revisited any time the business changes shape materially.

A business needs a controller once the close has enough at stake that nobody wants it going out unreviewed, once transaction volume or entity count has grown past what one bookkeeper can catch on their own, or once a lender, investor, or board expects to see internal controls that actually function rather than exist on paper. It fits companies that already have bookkeeping or general ledger maintenance running but no independent review layer checking that work before it becomes the official number. It is usually the right hire before a fractional CFO, not after: a CFO's forecasts and board narrative are only as good as the close underneath them, and a controller is what makes that close trustworthy in the first place. A very early-stage business with a single entity and low transaction volume may not need this yet; that gap typically opens up once payroll, multiple bank accounts, or outside capital enter the picture.

The most frequent gap is internal controls that exist as a policy document nobody actually follows: an approval limit that was written down once and then quietly ignored as spending grew, or a segregation-of-duties rule that broke down the day someone went on leave and nobody backfilled the second approver. The second is a close that goes out without anyone independent checking it first, so errors surface only when a lender or investor asks a pointed question. The third is a chart of accounts that has drifted differently across departments or entities, so consolidated reporting requires manual translation every single month. The fourth is silence between problems: nothing gets flagged until something is materially wrong, instead of a running memo that surfaces smaller issues while they are still cheap to fix. We address these by making review, sign-off, and a written memo a standing part of every close, not an occasional check when someone remembers to ask for one.

Controller review works inside whatever general ledger the business already runs. QuickBooks Online and Xero cover most single-entity and small multi-entity setups. NetSuite and Sage Intacct fit businesses with more complex consolidation, revenue recognition, or intercompany transactions that need a controller's sign-off across entities, not just within one. Bill.com is where the segregation-of-duties control usually lives in practice, since it separates who submits an invoice for payment from who approves it, with an audit trail attached. Where payroll systems like Gusto, ADP, or Rippling feed into the ledger, the controller's review extends to confirming payroll postings tie out correctly rather than treating that feed as a black box. If a business runs a system outside this list, we scope a short review of it before agreeing to ongoing controller work.

Controller-level review is typically layered on top of an existing bookkeeping or full-service accounting engagement rather than sold entirely on its own, since a review is only as reliable as visibility into how the numbers were built underneath it. On the US rate card, dedicated controller-level oversight and a CFO pack are part of the custom Scale tier, scoped after a review call that looks at entity count, transaction volume, and how much internal-controls work already exists versus needs to be built from scratch. Businesses further along on the Growth tier can add periodic controller review as a scoped add-on. Every fee is confirmed in writing before work starts.

The test for a controller function is whether problems get caught while they are still small and cheap, not whether the close simply goes out on time. Every month we track whether the review actually happened before sign-off, whether the controller's memo flagged anything material, and whether any flagged issue got resolved and documented rather than carried forward unresolved into the next period. Internal controls get periodically tested, not just assumed to be working because they were set up correctly once. If an approval limit or segregation-of-duties rule has quietly broken down, that is treated as a finding worth reporting, the same as an accounting error would be, because a control that exists only on paper protects nobody.

A controller reviews internal financial reporting; that review does not extend to signing your tax return, which stays with a credentialed preparer, or to issuing a compilation, review, or audit report, which only an independent, licensed accounting firm can provide. What the controller does is make the handoff to both of those parties cleaner: a tax preparer gets a ledger that already reconciles, and an auditor, if one is engaged, gets a set of books and controls documentation that has already been through an internal review rather than being seen for the first time during fieldwork. As entity count or transaction volume grows past what one controller review comfortably covers, that oversight extends into multi-entity accounting, scoped separately rather than stretched thin across an unchanged fee.
