The First 100 Days After Buying a Home Services Business

You closed the deal. The CIM looked clean, the quality of earnings came back reasonable, and the org chart had names in all the right boxes. Now you own a home services business. Buying a home services business is the easy part — what comes next is where the real work begins.

Whether you are an independent sponsor, a search fund operator, or a private equity-backed acquirer stepping into your first home services company — HVAC, plumbing, electrical, or roofing — this article is the tactical finance and operations playbook for your first 100 days post-close. Not strategy. Not theory. The actual work.

Here is the part nobody told you: the next 100 days will look nothing like the diligence process that got you here. The financial model that won the deal is not the skill set that runs the business. And the gap between what the CIM showed you and what you actually inherited is where most first-time acquirers get stuck.

We have helped dozens of operators navigate the transition after buying a home services business. This is the post-acquisition playbook we wish every one of them had at close.

What the CIM Showed You vs. What You Actually Inherited

The CIM gave you a clean P&L back to 2022 with quality of earnings adjustments. Books being maintained by the seller’s long-time CPA or bookkeeper. A talented, motivated team on the org chart. Field service software described as best-in-class. Documented processes, or at least that is what the diligence calls suggested.

Here is what you will actually find.

The books are being maintained, but the chart of accounts is a Frankenstein and the financials are on cash basis with no useful segmentation. The P&L exists, but it does not tell you anything actionable about which service lines are profitable or which crews are earning their keep.

The bookkeeper or accountant the seller used was either weak or had major gaps in day-to-day financial processes that the owner was personally filling. The owner was running payroll. The owner was paying bills. The owner was the one who knew which supply house to call for what, which portal had the insurance certificates, and where the passwords lived.

Vendor invoices are not centralized anywhere. They are sent to different email addresses, lost throughout the organization, paid by check or the owner’s personal card. There is no single place where all the financial paperwork lives.

And then there are the things you literally did not think about during diligence: logins to vendor portals, software subscription credentials, fleet management accounts, marketing platform access. All of it lived in the owner’s head or on sticky notes in the office. That owner is now transitioning out.

What Has to Work the Moment You Close

Before you think about strategy, optimization, or any of the value creation levers from your investment thesis, three things have to function on Day 1:

Accounts receivable. You have to be able to invoice customers and collect payment. If invoicing breaks for even a week, you are burning cash with no recovery mechanism.

Accounts payable. You have to be able to pay your vendors. Supply houses, subcontractors, and material suppliers do not care that you just closed an acquisition. They care that their invoice gets paid on time. Miss a payment and you lose terms, which means you are now paying cash upfront for materials.

Payroll. You have to be able to pay your team on time. This is non-negotiable. Miss a payroll cycle and you will lose technicians, dispatchers, and CSRs before you even learn their names. In a labor market where skilled tradespeople are already hard to find, you cannot afford to give anyone a reason to leave.

For each of these, you need to confirm who was doing it under the previous owner. If the answer is “the owner,” you now need a process in place, even if it is manual at first. These are not strategic activities. They are operational day-to-day financial tasks that PE professionals are not used to running. But if any of them breaks in week two, nothing else matters.

Building the Back Office From Scratch

Once the critical functions are stable, you need to stand up the infrastructure that makes the business actually manageable. Most of this is not glamorous, but skipping any of it creates problems that compound quickly.

Bank accounts under the new entity with proper signers. Get this done before close if possible. You need operating accounts, a payroll account, and potentially a separate account for customer deposits depending on your state’s requirements.

Credit cards in your name with employee sub-cards. No more personal Amex reimbursements. Techs and managers need company cards with limits and categories that flow into your bookkeeping system cleanly. Every reimbursement is a reconciliation headache.

A real payroll provider. Gusto, ADP, or Paychex. PTO tracking, deductions, and tax filings should all live in one place. If the seller was running payroll through their accountant’s manual process, migrate immediately.

AP automation. Bill.com or a similar platform that gives you one inbox for invoices, an approval workflow, and scheduled payments. The goal is to centralize every vendor invoice into a single system so nothing gets lost and nothing gets paid twice.

Billing through your field service platform. Whether it is ServiceTitan, Housecall Pro, or another ERP, your invoicing should originate in the system where the work is tracked and feed into QuickBooks cleanly. If billing lives in a separate spreadsheet or the owner’s email, you have a revenue recognition problem waiting to happen.

Centralized admin. Every login, password, vendor portal credential, and critical document needs to live in a system you and your team can find. A password manager and a shared drive are the minimum. The previous owner kept everything in their head. You cannot afford to do the same.

Tax Items to Flag Immediately

Three tax areas need attention in the first 30 days. You do not need to resolve them yourself, but you need a CPA looking at them right away.

Sales tax. What is taxable in your state? Home services sales tax rules vary significantly. Some states tax labor, some only tax materials, some tax both. Check for prior-period exposure. Is the company registered in every jurisdiction where it should be? According to the IRS state tax resource directory, requirements vary widely and non-compliance penalties can be substantial.

Payroll tax. Verify that withholdings are correct, federal and state filings are current, and there are no unfiled returns inherited from the seller. Payroll tax liabilities survive acquisitions.

Worker classification. W-2 versus 1099 misclassification is common in home services businesses. If the seller was treating technicians or installers as independent contractors when they should have been employees, the cleanup is now yours. The SBA’s employment classification guide outlines the key factors.

The Bookkeeper, the Controller, and the CFO

One of the first questions acquirers ask is what finance team they need. The answer depends on your size, but here is the general framework for home services.

At the revenue level where most acquisitions happen, around 3 to 10 million, you typically need a strong bookkeeper or outsourced controller handling day-to-day operations: AP, AR, payroll, reconciliations, monthly close. This person keeps the machine running. In home services, the bookkeeper and controller role are usually the same person, and they are almost always working on cash basis. That is the norm, but it creates real problems that we will address.

The fractional CFO is a separate seat entirely. The CFO is not doing the books. The CFO is doing quality assurance on the books and putting the right processes in place so that the operational finance components of the business are being done correctly and following best practices. Often what we see is that the bookkeeper or controller is not doing the books right, but also the day-to-day processes like making sure all invoices are in the same place, documentation standards, and reconciliation cadences are not being followed without a CFO providing oversight.

Most acquirers in the 5 to 15 million range benefit from both: a full-time controller or bookkeeper handling the day-to-day, and a fractional CFO providing the strategic layer, financial reporting structure, and operational finance oversight. These are two distinct roles and one does not replace the other.

Where the Low-Hanging Fruit Lives

Once the back office is stable and you can actually see your numbers, there are three categories where acquirers typically find the fastest improvements.

Marketing. Where does the spend go? Is it all profitable? Can any of it be reallocated? Most home services businesses are spending on marketing channels they cannot attribute. The SEO retainer with no measurable results. The print mailer that has run for five years because the owner never tested whether it works. The lead aggregator that sends low-quality leads at high cost. Kill the zombie spend first, then build attribution so you can allocate intelligently.

Fulfillment. This is the act of earning revenue: dispatching crews, completing jobs, billing. How do you do this for less without breaking the customer experience? Crew efficiency, truck utilization, callback rates, average ticket, and job completion time are all levers. But you can only pull them if you are tracking them, which brings us back to the data infrastructure problem.

Overhead. How much support function do you actually need at this revenue size? Who are the right people in the right seats? Most acquired businesses have overhead that scaled with the owner’s comfort level rather than the company’s actual needs. An honest assessment here usually surfaces savings.

The structural problem in small business is that there is no transparency, no peer data, and no shared playbook. You do not know what good looks like for a 7 million dollar plumbing company because there is no benchmark database to check. That is where working with a firm that has seen the inside of dozens of similar operations makes a real difference. We know what the numbers should look like because we have seen enough of them.

The Honest Reality: Who You Are vs. Who You Will Be Leading

Most acquirers in the ETA and independent sponsor space who end up buying a home services business come from finance and M&A backgrounds. PE, banking, consulting. Analytical, quantitative, transaction-oriented. Comfortable in the middle market and up, where market dynamics, structure, and capital allocation are the game.

Those skills earned you the deal. But they are not the skills that run the business.

In small business, market share is so low that market dynamics matter less than execution. The next million in revenue does not come from a thesis. It comes from showing up Monday and running the play. A perfect Excel model does not help if you cannot close out a tech’s payment on Tuesday.

And the people you will be leading are not the people you are used to working with. Blue-collar techs and journeymen. Marketers and creatives. Admins, dispatchers, CSRs, call center reps. People from all walks of life, most of whom do not think the way you think.

The shift is real. As an operator, you have to be good at everything: sales, marketing, people management, organizational design, process architecture. Finance is one piece of the pie. And while PE investors are generally considered more sophisticated, it is worth approaching with humility. You may be better than a founder at finance, but they are generally better than you at everything else it takes to run the business.

The question before you close, and the one worth sitting with during your first 100 days: which of those muscles is weakest?

The 100-Day Finance Checklist

Here is the condensed version. If you are buying a home services business and want to know exactly what to do and when, this is the sequence:

Days 1-7: Confirm critical operations. Verify AR invoicing works, AP payments are flowing, and payroll will run on schedule. Identify who was handling each function under the previous owner. If it was the owner, assign an interim process immediately.

Days 7-30: Stand up the back office. Open bank accounts under the new entity. Issue company credit cards. Set up a real payroll provider. Implement AP automation. Centralize all logins, passwords, vendor portals, and documents in one accessible system. Engage a CPA on sales tax exposure, payroll tax filings, and worker classification.

Days 30-60: Fix the financial reporting. Assess the chart of accounts and restructure if needed. Evaluate whether the books should move from cash to accrual basis. Ensure billing flows from your field service platform into QuickBooks cleanly. Hire or contract a bookkeeper or controller for day-to-day operations, and evaluate whether a fractional CFO is needed for financial oversight and process architecture.

Days 60-100: Build visibility into unit economics. Quantify marketing spend by channel and identify what is actually profitable. Measure fulfillment efficiency: crew productivity, average ticket, callback rates. Benchmark overhead against comparable home services businesses at your revenue level. Start making data-driven decisions instead of gut calls.

Frequently Asked Questions

What is the first thing to do after buying a home services business?

Confirm that accounts receivable, accounts payable, and payroll are all functional. These three processes keep the business alive. If any of them were managed personally by the previous owner, you need a replacement process in place before anything else.

How much does it cost to set up the back office for a home services acquisition?

The software and systems — payroll provider, AP automation, password manager, accounting software — typically run 500 to 2,000 dollars per month combined. The bigger cost is the bookkeeper or controller to run them, which ranges from 50,000 to 70,000 dollars annually for a full-time hire in home services, or less if outsourced. A fractional CFO for financial oversight and strategic reporting adds 5,000 to 12,000 dollars per month depending on scope.

Should I switch from cash to accrual accounting after an acquisition?

Almost always yes for management reporting, especially if revenue exceeds 3 million dollars. Cash-basis books do not show you real margins by service line, do not reconcile to your field service platform, and are not useful for any serious buyer if you plan to sell again. Most acquirers run accrual for management and cash for taxes. See our full breakdown in cash vs. accrual accounting for contractors.

Do I need a fractional CFO or a full-time controller?

At the 5 to 15 million dollar revenue range where most home services acquisitions happen, you typically need both. The controller handles day-to-day bookkeeping, AP, AR, payroll, and monthly close. The fractional CFO handles financial reporting quality, process design, KPI development, and strategic oversight. These are two different seats and one does not replace the other. More detail in our financial roles guide.

The Bottom Line

The first 100 days after acquiring a home services business are not about strategy. They are about survival infrastructure. Get payroll, AP, and AR working. Stand up the back office. Centralize everything the previous owner kept in their head. Fix the books so they actually tell you something useful. Then, and only then, start pulling the value creation levers.

If you are in the search process or recently closed, we work with acquirers through exactly this transition. The playbook above is what we have built from working with searchers across the home services industry.
