Backlog Cleanup: Fixing Messy Books Before (or With) Outsourced Accounting Support

Most business leaders know when their books aren’t right. Reconciliations haven’t been touched in months, expense categories don’t match reality, a year-end close takes twice as long as it should, or your board or lenders don’t fully trust your financial statements.

What’s less clear is what to do about it, and whether outsourced accounting can help before the books are in order. The short answer is yes. Backlog cleanup and outsourced accounting are often handled together, and the right provider will tell you that upfront.

What Messy Books Look Like

“Messy books” covers a wide range of problems, and the severity varies. Common issues include:

Unreconciled Bank and Credit Card Accounts

Accounts that haven’t been reconciled in months, or in some cases years, are among the most common backlogs. Unreconciled accounts mean your general ledger doesn’t match your actual cash position, which makes every financial report that flows from it unreliable.

Miscategorized or Missing Transactions

Expenses coded to the wrong account, transactions that were never entered, or duplicate entries distort your profit and loss statement and make tax preparation significantly more complicated. In some cases, miscategorization persists across multiple years, requiring a retroactive review before current-year books can be closed accurately.

Incomplete or Inconsistent Chart of Accounts

A chart of accounts that has grown organically over time creates confusion for anyone trying to read your financials. Redundant categories, vague descriptions, and accounts that no longer reflect how your business operates are all common culprits. Cleaning this up is often a prerequisite to producing reliable reports.

Payroll and Benefits Discrepancies

Payroll entries that don’t reconcile to payroll provider reports, benefits costs that weren’t recorded, or employer tax liabilities that weren’t accrued properly are common in organizations that have outgrown their accounting software and surrounding processes.

Outstanding Accounts Receivable or Payable

Aged receivables that were never written off and weak accounts payable practices that leave vendor bills unpaid or payments applied to the wrong invoices create a distorted picture of your cash position and obligations.

What the Backlog Cleanup Process Involves

The cleanup process depends on how far back the problems go and how severe they are. A provider doing this work will typically start with a diagnostic review, assessing the state of your accounts, identifying the oldest unreconciled period, and scoping the work before committing to a timeline. From there, cleanup generally follows a logical sequence:

• Reconciling accounts from oldest to most recent
• Correcting miscategorized transactions
• Resolving discrepancies between your records and external statements
• Producing restated financial reports once the underlying data is accurate

For organizations with multiple years of backlog and moderate issues, the process can take several weeks. For a single year with moderate issues, a focused engagement of a few weeks is more typical. Either way, the goal is to arrive at a clean, auditable set of books that accurately reflects the organization’s financial history.

“We see messy books all the time. It’s not unusual. Most of the time, once we get into the records and establish a sequence, it moves faster than the client expected,” Mark Leverette says.

Where Outsourced Accounting Fits In

Some organizations wait until their books are clean before handing off books to an outsourced accounting provider. That’s understandable, but it’s not always necessary. Many providers, including firms with dedicated cleanup experience, will take on backlog work as part of an onboarding engagement, handling the remediation and then transitioning directly into ongoing accounting support.

One of the benefits of outsourced accounting services is that the professionals doing the cleanup learn your business, your accounts, and your historical quirks firsthand. By the time ongoing accounting begins, there’s no handoff gap and no re-explanation of how the books got to where they are.

“When we do the cleanup and then stay on, we already know where everything lives and why it looks the way it does. There’s no handoff, no re-explaining – we just keep going,” Mark Leverette says.

If you’re approaching an audit, a fundraising round, or a lender review, the timeline is crucial. Cleanup that happens alongside outsourced accounting onboarding moves faster than cleanup handled in isolation, because the provider has the staffing and institutional knowledge to work efficiently.

How BPM Approaches Backlog Cleanup

BPM’s outsourced accounting services guide organizations through every stage of financial readiness, including those whose books need remediation before ongoing accounting support can begin. The diagnostic review that opens a cleanup engagement also informs how BPM structures the ongoing relationship, so the transition from remediation to regular accounting is direct and well-scoped.

For organizations facing an imminent deadline, whether an audit, a board presentation, or a financing event, BPM can prioritize the periods and accounts that matter most, producing reliable reports for the immediate need while cleanup continues in the background. Whatever your starting point, the goal is the same: books you can stand behind. Contact us today to learn more about how BPM’s outsourced accounting professionals can help.
