A $22M PE-backed industrial services company ("Apex Industrial Services") had been acquired 8 months prior but was still running on printed QuickBooks P&Ls delivered 45 days after month-end. No management accounts, no KPI tracking, no variance analysis, no cash flow forecast. Within 60 days, we cleaned an 847-line chart of accounts down to 142, fixed revenue recognition, built a PE-grade monthly board pack with divisional P&Ls and bridge analysis, and implemented a KPI dashboard with 13-week rolling cash. Close time dropped to 8 business days. AR collections recovered $860K in the first 90 days. EBITDA was restated $420K higher once accounting errors were corrected. Total cost: $5,995/month vs. the $240K+ they'd budgeted for a full-time controller they couldn't find.
The Phone Call From the Operating Partner
I got the call on a Tuesday afternoon. David, an operating partner at a lower-middle-market PE fund with seven portfolio companies, was direct in a way that only PE operating partners can be:
"We closed on Apex eight months ago. I still can't tell you what the real EBITDA is. The bookkeeper emails me a QuickBooks P&L — printed to PDF, landscape orientation, 12 pages long — about six weeks after month-end. That's everything I get. No management accounts, no KPIs, no cash forecast. I've been trying to hire a controller for three months and every decent candidate wants $185K plus benefits. Can you fix this?" — David, Operating Partner
This is not an unusual situation. In fact, it's closer to the norm than PE firms would like to admit. The deal thesis was sound — Apex Industrial Services (name disguised) was a $22M revenue industrial services company with three distinct service lines, strong customer retention, and meaningful barriers to entry. The financials, however, had not been touched since acquisition. The prior owner had run the business on cash-basis QuickBooks and gut instinct for twelve years. The PE fund bought the company, replaced the CEO, and then discovered that nobody had ever built the reporting infrastructure to actually manage the investment.
David's problem wasn't unusual. His timeline was. He had a quarterly board meeting in nine weeks, and he needed to present a credible set of management accounts for a company that, at that moment, couldn't produce a departmental P&L.
PE firms acquire companies based on a financial thesis — projected EBITDA growth, margin expansion, operational efficiency gains. But if you can't measure any of those things because the reporting infrastructure doesn't exist, the thesis is just a hope. Apex had no way to prove whether the investment was performing. Eight months in.
Week 1: The Discovery Audit
I spent the first week onsite — or rather, logged into their QuickBooks Desktop file, their shared drive of Excel spreadsheets, and a series of increasingly uncomfortable phone calls with their bookkeeper of nine years, Linda. Linda was not the problem. Linda was doing exactly what she'd been asked to do: enter bills, cut checks, and print a P&L once a month. Nobody had ever asked her to do more. Nobody had built anything for her to do more with.
Here's what the discovery audit revealed:
Chart of Accounts: 847 Line Items
The chart of accounts had accumulated 847 line items over twelve years. Of those, 214 were duplicates created when someone couldn't find the right account and made a new one (there were three separate accounts for "Office Supplies," two for "Truck Fuel," and — memorably — one called "Misc Stuff"). Another 133 were inactive accounts that hadn't been used in over three years. The remaining 500 were a mix of legitimate accounts and granular sub-accounts that nobody used for reporting because nobody did reporting.
Revenue Recognition: Cash Basis on an Accrual Company
Apex filed taxes on the accrual basis. Their CPA made adjusting entries once a year at tax time. But internally, the books ran on cash basis — revenue was recognized when the check cleared, not when the work was performed. For a services business that invoices on completion and collects 30-60 days later, this created monthly revenue swings of 15-25% that had nothing to do with actual business performance. The PE operating partner was looking at revenue numbers that were, in any given month, essentially meaningless.
No Departmental or Divisional P&Ls
Apex had three distinct service lines — mechanical services, electrical services, and facilities maintenance — each with different gross margins, different labor models, and different customer profiles. All three were dumped into a single P&L. There was literally no way to tell which division was profitable, which was growing, or which was dragging down the blended margin. For a PE fund evaluating whether to invest further in one division or divest another, this was flying blind.
- 847 chart of accounts line items — 347 duplicates or inactive
- Cash-basis revenue recognition despite accrual tax filing
- Zero departmental P&Ls across 3 distinct service lines
- $1.2M in AR over 60 days with no collection process
- Inventory "estimated" monthly — no counts, no tracking
- Bank recs 3 months behind
- No budget, no forecast, no variance analysis
- Monthly close: 45 calendar days
Accounts Receivable: $1.2M Over 60 Days
The AR aging told a story all by itself. $1.2M was sitting in the 60+ day buckets. Some invoices were over 120 days. When I asked about the collection process, Linda said, "I send statements every month." That was it. No follow-up calls, no escalation process, no past-due holds on new work. The company was effectively financing its customers' cash flow to the tune of $1.2M — while simultaneously drawing on its own line of credit to cover payroll. The PE fund was paying interest on money their portfolio company had already earned but hadn't bothered to collect.
Inventory and Bank Reconciliations
Inventory was carried at a flat estimate — someone had decided it was "about $180K" and that number hadn't changed in seven months despite ongoing purchases and usage. Bank reconciliations were three months behind, meaning nobody actually knew how much cash the company had. I found $34K in unrecorded bank fees and $12K in duplicate payments that hadn't been caught because nobody was looking.
I've audited the books of over thirty PE portfolio companies at this stage. The pattern is remarkably consistent: the deal team underwrites the financials based on tax returns and a CPA-prepared review, but nobody checks whether the internal books can actually produce the monthly management reporting the fund needs to manage the investment. The gap between "the books are fine for tax purposes" and "the books support PE-grade management reporting" is a chasm. It usually takes 60-90 days to bridge.
The 60-Day Fix: Three Phases
I presented David with a three-phase plan. Each phase had a clear deliverable, a hard deadline, and a specific outcome the PE fund could measure. No ambiguity, no "ongoing improvements." Ship it or explain why not.
Phase 1: Foundation Repair (Weeks 1-2)
Clean the chart of accounts. Fix revenue recognition. Reconcile all bank accounts. Get the books to a point where the numbers mean something.
Phase 2: Board Pack Build (Weeks 3-4)
Design and deliver a PE-grade monthly management pack: executive summary, divisional P&Ls, bridge analysis, AR/AP aging, cash flow forecast, 13-week rolling cash model.
Phase 3: KPIs and Infrastructure (Weeks 5-8)
Build the KPI dashboard, create the annual budget with monthly variance tracking, implement the AR collection process, and train Linda on the new close procedures.
Phase 1: Foundation Repair (Weeks 1-2)
The chart of accounts went from 847 line items to 142. Every account mapped to a specific line on the management P&L. Every account had a clear owner, a clear purpose, and a clear mapping to one of the three service divisions. I built the divisional structure using QuickBooks classes — mechanical, electrical, facilities maintenance, and corporate overhead — so that a single transaction could be tagged to its division without duplicating accounts.
Revenue recognition moved to proper accrual. I built a revenue recognition schedule that matched revenue to the period work was performed, not the period the check arrived. This alone eliminated the 15-25% monthly revenue swings and gave the PE fund a number they could actually trend.
Bank reconciliations were brought current. The $34K in unrecorded fees was booked. The $12K in duplicate payments was identified and recovery initiated. Three months of reconciling work was completed in four days because — and this is important — the backlog wasn't caused by complexity. It was caused by nobody prioritizing it.
Phase 2: The Board Pack (Weeks 3-4)
This is where the value becomes visible. A PE-grade board pack isn't a QuickBooks P&L with a cover page. It's a structured document that tells an operating partner everything they need to know about the business in 15 minutes. Here's exactly what we built:
Executive Summary (1 page)
Revenue, EBITDA, and cash position vs. budget and prior year. Three bullet points on what went well, three on what needs attention. No narrative — just signal.
Consolidated P&L with Budget Variance (1 page)
Current month and YTD actuals vs. budget. Dollar and percentage variance for every line. Color-coded: green for favorable, red for unfavorable, gray for immaterial.
Divisional P&Ls — Mechanical, Electrical, Facilities (3 pages)
Each division's revenue, direct costs, gross margin, and allocated overhead. The operating partner could now see that Facilities was running at 41% gross margin while Electrical was at 28% — a gap nobody knew existed.
Revenue Bridge (1 page)
Month-over-month revenue walk: prior month → new contracts → expansion revenue → churn/lost contracts → current month. Shows exactly where growth or decline is coming from.
EBITDA Bridge (1 page)
Prior month EBITDA → revenue impact → gross margin changes → SG&A changes → one-time items → current month EBITDA. This is the page PE operating partners flip to first.
AR & AP Aging (1 page)
Current, 30-day, 60-day, 90-day, 120+ day buckets with trend arrows. Top 10 past-due customers with notes and expected collection dates.
13-Week Rolling Cash Forecast (1 page)
Week-by-week cash inflows, outflows, and ending balance. Tied to the AR aging (expected collections) and AP schedule (committed payments). Highlights any weeks where cash drops below the safety threshold.
KPI Dashboard (1 page)
Revenue per employee, gross margin by division, DSO, DPO, EBITDA margin, headcount, and customer concentration — all with trend arrows and 3-month rolling averages.
Want to see what a board pack like this actually looks like?
See our sample board pack →The first board pack was delivered 26 days after engagement. David's reaction: "This is the first time in eight months I've actually understood what's happening in this business." The quarterly board meeting happened two weeks later. The pack was presented. David told me afterward that the managing partner used the phrase "night and day."
Phase 3: KPIs and Infrastructure (Weeks 5-8)
A board pack is a snapshot. It tells you where you are. The KPI dashboard and budget variance framework tell you whether you're on track — and if not, where you're drifting. Phase 3 was about building the infrastructure so the board pack practically writes itself every month.
The KPI dashboard tracked eight metrics that mattered to the PE fund's thesis:
| KPI | Baseline (Month 1) | Target | Month 3 Actual |
|---|---|---|---|
| Revenue per Employee | $18,400/mo | $21,000/mo | $20,100/mo |
| Blended Gross Margin | 34.2% | 38.0% | 36.8% |
| EBITDA Margin | 8.1% | 12.0% | 10.4% |
| DSO (Days Sales Outstanding) | 67 days | 38 days | 41 days |
| DPO (Days Payable Outstanding) | 29 days | 35 days | 33 days |
| AR Over 60 Days | $1.2M | < $200K | $340K |
| Monthly Close (Business Days) | 45 calendar days | 10 business days | 8 business days |
| Customer Concentration (Top 5) | 61% | < 50% | 57% |
The annual budget was built from the ground up. Not a flat percentage increase over prior year — a bottoms-up build by division, by month, with assumptions documented for every line item. Revenue was built from the contract backlog and pipeline. Labor was built from headcount plans. Materials were built from historical usage rates adjusted for known price increases. The result was a budget the PE fund could actually hold management accountable to, because management had built it and agreed to it.
The AR collection process was the highest-ROI piece of work in the entire engagement. It wasn't sophisticated — a structured cadence of calls and emails at 30, 45, 60, and 75 days, with escalation to the division manager at 60 and to the CEO at 90. Past-due holds on new work orders for any customer over 90 days. Weekly AR review meetings every Monday at 8 AM. Linda ran the process. She was, it turned out, extremely effective at collections once someone gave her permission and a process to follow.
$860K collected in the first 90 days. The oldest invoice collected was 147 days past due — a $78K mechanical services job that the customer had simply never been asked to pay. DSO dropped from 67 days to 41. The company's line of credit utilization dropped from 82% to 34%. David's comment: "You paid for two years of your own fees in the first three months just from collections."
The Hidden $420K: Why the Real EBITDA Was Higher Than Reported
This is the finding that changed the PE fund's view of the entire investment. When I rebuilt the financials on a proper accrual basis and corrected the inventory valuation, the trailing twelve-month EBITDA was $420K higher than what had been reported to the fund for the prior three quarters.
The three drivers:
- Revenue recognition timing ($218K impact). Cash-basis reporting had been pushing December and January revenue into February and March, understating Q4 and Q1 results. On a proper accrual basis with revenue matched to service delivery, the trailing twelve-month revenue was $218K higher.
- Inventory valuation ($127K impact). The flat $180K estimate had been understating actual inventory by an average of $127K over the trailing twelve months. A proper cycle count established actual inventory at $307K, and the monthly consumption tracking going forward meant the balance sheet was now reliable.
- Expense misclassification ($75K impact). Several capital expenditures had been expensed rather than capitalized — including a $48K service vehicle and $27K in equipment. These should have been on the balance sheet with depreciation flowing through the P&L. Correcting the classification added $75K back to EBITDA.
At a 5-6x EBITDA multiple — standard for lower-middle-market industrial services — that $420K EBITDA correction represented $2.1M to $2.5M in enterprise value that had been invisible because the books couldn't surface it. David's managing partner called me directly after seeing the restated numbers. Not to question them — to ask how quickly I could do the same analysis on two other portfolio companies.

The Economics: Why This Wasn't a $185K Problem
David had been trying to hire a full-time controller for three months. The market rate for someone who could build PE-grade reporting in the Houston industrial services market was $185K base salary. Add benefits, payroll taxes, and the recruitment fee, and the all-in first-year cost was approaching $260K. And he still hadn't found the right person — because the candidates who can do this work have options, and a $22M industrial services company in the suburbs isn't always at the top of their list.
| Cost Component | Full-Time Controller | Fractional (BlackpeakCFO) |
|---|---|---|
| Base Cost | $185,000/year | $71,940/year ($5,995/mo) |
| Benefits & Payroll Tax | $55,500/year | $0 |
| Recruiting Fee (25%) | $46,250 (one-time) | $0 |
| Ramp Time | 60-90 days to productivity | Delivering in Week 1 |
| First-Year All-In | $286,750 | $71,940 |
| PE Portfolio Scalability | One company only | Deployable across portfolio |
The math isn't even close. But the real advantage isn't the cost — it's the speed and the pattern recognition. A full-time controller hire would have spent their first 60 days learning the business. I'd seen this exact situation thirty times before. I knew which chart of accounts structure works for PE-backed industrial services companies because I've built it before. I knew what the board pack needed to contain because I've presented to PE operating partners before. The playbook existed. It just needed to be executed.
Within six months, David deployed me across two additional portfolio companies. Same playbook, adapted to each company's industry and complexity. The PE fund now has consistent, comparable management reporting across three portfolio companies — delivered by the same person who understands the fund's standards and the managing partner's preferences. That consistency is impossible with three different full-time controllers at three different companies.
What PE Funds Get Wrong About Portfolio Company Finance
After working with over a dozen PE-backed companies, I see the same pattern. The deal team does rigorous financial diligence before close. They scrutinize the Quality of Earnings report. They negotiate reps and warranties. Then they close — and assume that the existing finance function can produce the management reporting the fund needs to monitor the investment. It almost never can.
Here are the three assumptions that repeatedly prove wrong:
1. "The CPA will handle it."
Your CPA does taxes and maybe a year-end review. They don't build monthly management accounts, divisional P&Ls, bridge analyses, or 13-week cash forecasts. That's not what they do. That's not what you're paying them for. The gap between "CPA-maintained books" and "PE-grade management reporting" is the gap this engagement fills.
2. "We'll hire a controller after close."
Maybe you will. In three to six months, after a recruiting process, at $185K+ in a competitive market. Meanwhile, you're flying blind for two or three quarterly board meetings. The fractional model fills the gap immediately — and in many cases, the fractional engagement becomes the permanent solution because the economics and flexibility are simply better for a company this size.
3. "The bookkeeper just needs better tools."
Linda was perfectly competent. The problem was never Linda's skill — it was that nobody had designed the systems, built the reporting framework, or defined the close process. A bookkeeper executes a process. Someone has to design the process first. That's the controller function. That's what was missing.
The most expensive mistake I see PE funds make isn't overpaying for an acquisition. It's waiting 12-18 months to install proper reporting infrastructure after close. Every month without real management accounts is a month where operational problems compound invisibly. The $420K EBITDA gap at Apex had been there since day one — but it took eight months for anyone to look hard enough to find it.
The Key Takeaway for PE Operating Partners
PE firms don't buy companies to hope the numbers are right. They buy companies and install the reporting infrastructure to prove it. The question isn't whether you need that infrastructure — you do, from day one — but how you build it.
A fractional CFO or controller builds it at a third of the cost of a full-time hire. They bring pattern recognition from doing it repeatedly across similar companies. They can be deployed in weeks, not months. And critically, they can be deployed across multiple portfolio companies, bringing consistency and comparability to fund-level reporting.
Apex went from "we have QuickBooks" to "here's your board pack, eight business days after month-end, with divisional P&Ls, bridge analysis, a KPI dashboard, and a 13-week cash forecast." The PE fund's investment thesis was validated — and in fact, the actual performance was $420K better than they thought.
The only thing that changed was the ability to measure it.
"We spent three months trying to hire a controller we couldn't find. Stuart had the board pack built in less time than it took us to schedule the first round of interviews. If you're a PE fund with portfolio companies running on QuickBooks and gut instinct, stop waiting for the perfect hire. This is the faster, cheaper, better path." — David, Operating Partner
