Bookkeeping Case Study: From 18 Months Behind to
Predictable Monthly Reporting

Project Overview

A service-based business came to Bookkeep Boss as a referral from their CPA after spending six months working with a previous bookkeeper while the project was stuck in cleanup.

The business needed its 2025 bookkeeping to finally be completed so the CPA could move forward with preparing the tax return before the extended filing deadline. At the same time, 2026 bookkeeping was continuing to fall behind. The business was earning more than it had the year before, and the owners needed current financial information to begin tax planning.

In prior years, the CPA had needed to reconstruct portions of the bookkeeping in order to prepare the tax returns. That workaround was no longer sustainable, and both the CPA and the client wanted the bookkeeping completed before tax preparation began.

When we reviewed the QuickBooks Online file, we found uncategorized transactions, misclassified transactions, and accounts that had not been reconciled since the end of 2024. An entire credit card was missing from the file, paid Accounts Receivable invoices remained open, and other historical balances needed to be verified or cleared before the financial records were ready for tax preparation and current reporting.

The client was not only trying to finish the past. They needed to get ahead of the bookkeeping so they could finally start planning for the future.

The engagement covered January 2025 through June 2026. Bookkeep Boss first completed the 2025 cleanup for tax preparation, then brought January through June 2026 current before moving the client into ongoing monthly bookkeeping beginning with July.

By the end of August, the client had moved from an overwhelming 18-month backlog into a predictable monthly bookkeeping and reporting process.

Introductory Call

During the introductory call, we discussed the 18-month backlog, the work that had already been attempted by a previous bookkeeper, the client’s tax-filing timeline and their goal of getting the current year caught up with enough time remaining for their tax professional to do tax planning.

Before determining the scope and price of the cleanup, we needed to understand what was really going on inside the QuickBooks Online file.

After determining we were a good fit to work together, we offered the paid Bookkeeping Review & Roadmap as the next step. We explained that this service would allow us to review the file in depth to determine what had already been completed, uncover what still needed work and develop a path forward based on what their bookkeeping needed.

We also explained that the Review & Roadmap was more than a way for us to access their QuickBooks Online file or prepare a quote. It would give them an understanding of their bookkeeping, what needed attention and what the next steps should be, whether they chose to have us complete the work, work with another bookkeeper or use the findings to have a more informed conversation with their CPA.

Bookkeeping Review & Roadmap

They agreed to the paid Bookkeeping Review & Roadmap, allowing us to review the QuickBooks Online file.

As part of the review, we compared QuickBooks activity and balances against bank statements, credit card statements, payroll reports and other supporting documentation to evaluate whether the accounts and reported balances were supported.

The review identified that:

• Accounts had not been reconciled since the end of 2024.
• An entire credit card was missing from the QuickBooks Online file, including business expenses that needed to be captured for tax preparation.
• About 35 paid Accounts Receivable invoices were still showing as open and needed to be matched to the related deposits.
• Journal entries had been posted to a reconciliation discrepancy account to force accounts into balance rather than resolving the differences.
• Some transactions had been categorized incorrectly.
• Business and personal activity had been mixed together.
• Venmo and PayPal activity required transaction-level detail so the related deposits and expenses could be recorded properly.
• Historical Balance Sheet balances needed to be verified or cleared.

The completed review provided the detail needed to define the work, determine the cleanup and catch-up scope, price the project and develop a path toward ongoing monthly bookkeeping. We then prepared to present the findings, scope and recommended path forward to the owner during the Findings, Scope & Pricing Call.

Findings, Scope & Pricing Call

After completing the Bookkeeping Review & Roadmap, we scheduled a phone call with the client to walk through the findings, explain the scope of the cleanup and catch-up work, and review pricing for the project and ongoing monthly bookkeeping.

Before the call, we emailed the Findings Report, pricing sheet and a copy of the Balance Sheet to the client.

During the call, we explained how the findings from the review affected the scope of the project and why the work needed to be completed in a specific order.

The recommended plan was divided into three phases:

2025 Cleanup Bookkeeping: January through December 2025

The first priority was completing the 2025 cleanup so the client’s CPA could move forward with tax preparation.

2026 Catch-Up Bookkeeping: January through June 2026

Once the 2025 cleanup was complete, we would continue with January through June 2026 to bring the current-year bookkeeping up to date.

Ongoing Monthly Bookkeeping: Beginning July 2026

With the cleanup and catch-up work complete, the client could then move into ongoing monthly bookkeeping and reporting.

The client agreed to move forward with the recommended plan.

How the Client Moved Through the Process

Introductory Call → Paid Bookkeeping Review & Roadmap →

Findings, Scope & Pricing Call → Cleanup Bookkeeping →

Quality Check & Verification → Year-End Tax Professional Handoff

2025 Cleanup Bookkeeping

The first phase focused on completing the January through December 2025 bookkeeping so the client’s CPA could move forward with tax preparation.

The year included approximately 2,300 transactions across the business checking account, savings account and six credit cards.

We reviewed and categorized the activity, researched transactions that required additional information, added the missing credit card to QuickBooks and reconciled the accounts to their supporting statements. We also matched open Accounts Receivable invoices to the related bank-feed deposits and worked through expenses and deposits related to the reconciliation differences identified during the Review & Roadmap.

For Venmo and PayPal activity, the client provided spreadsheet breakdowns of the individual deposits and expenses. We used that detail to split the related bank-feed transactions so the bookkeeping reflected the actual activity.

We also reviewed transactions that required Balance Sheet treatment rather than ordinary income or expense categorization. One example was a $3,100 computer purchase that had been recorded as an operating expense. We reclassified the purchase to the appropriate fixed asset account.

Payroll activity was incorporated into the bookkeeping for the business’s two employees, with payroll processed through an outside provider that handled the related payroll-tax payments.

2025 Quality Check & Verification

After completing the 2025 cleanup, we performed a Quality Check & Verification to confirm the bookkeeping was complete and supported. This provided a checkpoint between completing the bookkeeping and preparing the information and reports that would move forward to the CPA for tax preparation.

We reviewed reconciliations for uncleared balances, tied Balance Sheet accounts to supporting statements and documentation, matched payroll activity to the payroll summary reports, and reviewed the financial statements for consistency and accuracy.

Any items requiring additional research or input from the client’s CPA were noted before the year-end review and tax professional handoff.

Year-End Tax Professional Handoff

Once the 2025 bookkeeping had passed Quality Check & Verification, we reviewed the completed year as a whole before preparing the financial information for the client’s CPA.

We reviewed the Balance Sheet and Profit & Loss for year-end items, unusual balances, asset activity and anything that required additional documentation or CPA input for tax preparation.

Bookkeep Boss then prepared the Bookkeeping Package, which included:

• Year-End Bookkeeping Package Summary
• Profit & Loss
• Balance Sheet
• General Ledger
• Cash- and accrual-basis reports where needed
• PDF and Excel versions of applicable reports
• Year-end account balances supported by completed reconciliations and available year-end statements

The completed package gave the CPA an organized set of financial records to work from without having to reconstruct the bookkeeping or determine whether the reported account balances had been reconciled.

Less than a month after beginning the process with Bookkeep Boss, the 2025 bookkeeping was ready for the client’s CPA. The client was especially happy with the progress after having spent the previous six months trying to move the bookkeeping out of cleanup.

This completed the 2025 bookkeeping handoff and allowed tax preparation to move forward while Bookkeep Boss continued bringing the 2026 bookkeeping current.

2026 Catch-Up Bookkeeping

Once the 2025 cleanup was complete, we moved into the January through June 2026 catch-up work.

Approximately 1,550 transactions were still sitting in the QuickBooks bank feed for those six months. We worked through the activity, researched transactions that required additional information and reconciled the bank and credit-card accounts to their supporting statements.

Business and personal activity was also mixed together, so transactions were reviewed to separate business activity from personal spending.

The business had grown from two employees in 2025 to four employees in 2026, so payroll activity continued to be incorporated into the bookkeeping and financial reporting.

By the end of June, the full 18-month backlog had been completed.

2026 Quality Check & Verification

After completing the January through June 2026 catch-up, we repeated the Quality Check & Verification process.

We reviewed reconciliations for uncleared balances, tied Balance Sheet accounts to supporting statements and documentation, matched payroll activity to the payroll summary reports, and reviewed the financial statements for consistency and accuracy.

This confirmed that the catch-up work was complete and the reported balances were supported before the client moved into ongoing monthly bookkeeping.

Ongoing Monthly Bookkeeping & Reporting

Once the bookkeeping was current through June 2026, the client transitioned into ongoing monthly bookkeeping.

July 2026 was the first regular monthly bookkeeping cycle following the 18-month backlog.

The client was especially happy to reach this stage after spending months trying to get the bookkeeping out of cleanup and finally having financial records that could be maintained on a monthly schedule.

As part of the ongoing process, we created a shared spreadsheet for transactions that required additional information from the client. They received a link to review open items and provide details about what the transactions were for or how they should be categorized. This established a consistent process for resolving questions each month before reporting was completed.

The monthly process included reviewing and categorizing transactions, reconciling accounts, reviewing Balance Sheet activity, resolving open items and preparing current Balance Sheet and Profit & Loss reports.

The August 2026 month-end close was completed on September 9, 2026, giving the client current financial information early in the following month.

The business had moved from historical cleanup and catch-up work into a predictable monthly bookkeeping and reporting process that could support business decisions and provide current financial information for conversations with their CPA, including tax planning.

Financial Reporting for CPA Tax Planning

One of the goals of bringing the bookkeeping current was making the financial information available in time for tax planning.

With the business now on a current monthly reporting schedule, the client was able to schedule their tax-planning appointment with their CPA. This was the first time in seven years in business they had reached this point.

The CPA was happy with how the engagement had gone and felt informed throughout the process. Instead of spending valuable time reconstructing bookkeeping or working around missing information, he could focus on planning for the future with the client.

About This Case Study

This case study reflects actual cleanup, catch-up and ongoing monthly bookkeeping completed by Bookkeep Boss in a service-based business’s QuickBooks Online file covering January 2025 through June 2026, followed by ongoing monthly bookkeeping beginning in July 2026.

The work followed a reconciliation-focused approach. QuickBooks account activity and Balance Sheet balances were compared with available source documents, including bank statements, credit card statements, payroll reports, Venmo and PayPal transaction detail, and other supporting documentation provided by the client.

The work described included bookkeeping cleanup and catch-up, account reconciliations, Accounts Receivable review, Balance Sheet verification, payroll review, financial report preparation, year-end bookkeeping reports prepared for the client’s CPA, and ongoing monthly bookkeeping and reporting. It did not include tax return preparation, tax advice, tax planning, legal advice, audit services or assurance services. Tax planning, tax treatment and filing decisions remained with the client’s CPA.

This case study also highlights the Bookkeep Boss client experience, which moved from an introductory call to a paid Bookkeeping Review & Roadmap, Findings, Scope & Pricing Call, cleanup bookkeeping, Quality Check & Verification, year-end CPA handoff, catch-up bookkeeping and ongoing monthly bookkeeping and reporting.

The 2025 bookkeeping was ready for the client’s CPA less than one month after the process began. After the January through June 2026 catch-up was completed, July and August became the first regular monthly bookkeeping cycles, with the August close completed on September 9, 2026. For the first time in seven years in business, the client had current financial information available for a tax-planning conversation with their CPA.

This case study shows how a review-first, reconciliation-focused bookkeeping process can move a business from an 18-month backlog into current monthly bookkeeping and reporting, while giving the client and CPA organized financial information they can use to move from reconstructing the past to planning for the future.
