6 Ways Acquisition Entrepreneurs Sabotage Their First 90 Days Without Knowing

6 Ways Acquisition Entrepreneurs Sabotage Their First 90 Days Without Knowing

You closed the deal. Wire hit. Keys turned. The hard part is supposed to be behind you.

It's not. The first 90 days after the close are where most acquisition entrepreneurs quietly create problems they'll spend the next year cleaning up. None of it feels like a mistake at the time. That's the whole issue.

Here are six of the most common ones — what they look like, why they bite, and what an operator who's done this before does instead.

1. Keeping the seller's bookkeeper out of loyalty

The seller introduces you to Linda. Linda has been doing the books for fourteen years. She knows where everything is.

That's the problem.

Books built by the seller's bookkeeper were built to match how the seller thought about the business — which often means they were built to obscure rather than reveal. Owner expenses sprinkled through G&A. A chart of accounts that buckets everything into "supplies." Vendor categorizations that hide where margin actually lives.

Keeping that bookkeeper feels like continuity. It's actually inheriting a structure designed for someone else's tax position and someone else's comfort. Plan the transition in writing on day one, even if you keep Linda for the handoff window.

2. Not rebuilding the chart of accounts

Most acquired companies have a chart of accounts that looks fine and reports nothing useful.

A distribution business with three product lines and one "Sales" account can't tell you which product line makes money. A home services company with "Labor" lumped together can't separate technician cost from office overhead. Margin lives in the chart of accounts. If the structure doesn't expose it, no report you build downstream will.

System Six does this rebuild on a regular cadence for search funds and acquisition operators — usually within the first 30 days post-close, with the new department and product-line cuts already in place before the first monthly close runs.

If the chart of accounts doesn't change in the first 60 days, the new owner inherits the old owner's blind spots and then has to spend a year convincing the bookkeeper to fix it.

3. Missing the SBA loan's covenant reporting until the bank asks

Most SBA 7(a) acquisition loans include reporting covenants. Quarterly financials. Annual reviewed or audited statements, depending on the loan amount. Debt service coverage ratio at certain thresholds. Sometimes a working capital floor.

These are in the loan documents. Nobody reads them after the close.

The first time the bank asks is six months in, and the response is a fire drill: pull together a P&L the bookkeeper didn't structure for that purpose, reconcile a balance sheet that's three months stale, prove a covenant ratio you've never calculated. A routine filing becomes a week of weekend work and a slightly less patient banker.

Build the covenant calendar into the close checklist. Calculate the ratios monthly even when you don't have to file them. The bank's not testing whether you're profitable — they already know that. They're testing whether you know what you bought.

4. Running the acquired entity's payroll on the old system without confirming multi-state registrations

The seller had three employees in Texas. Then they hired one remote in Colorado. Then one in Pennsylvania. They never updated the payroll system. They never registered with the state unemployment or income tax authorities in either new state.

You inherited all of that, including the unfiled-return exposure.

Multi-state payroll registration is one of the cheapest things to fix and one of the most expensive things to ignore. Each state has its own unemployment account, withholding account, and (sometimes) workers' comp filing. Missing them stacks up penalties that compound monthly.

In a clean 90-day plan, you confirm the residence state of every W-2 employee in the first week, pull current registration status in each state, and either confirm or initiate every missing registration before the next pay run.

This isn't sexy work. It's also the cheapest insurance an acquirer ever buys.

5. Waiting until tax season to learn the deal's structure created a basis and depreciation picture nobody modeled

You bought assets, not stock. Or you bought stock and made a Section 338(h)(10) election. Or you did a forward triangular merger and you're not entirely sure what got stepped up.

If you don't know which of those is true on day 30, your first tax return is going to surprise you.

The deal structure dictates basis. Basis dictates depreciation. Depreciation dictates how much of your year-one cash flow ends up as taxable income. An asset purchase with a clean step-up under IRC §1060 can mean tens of thousands of dollars of first-year depreciation on equipment and goodwill. A stock purchase without a 338 election means you inherit the seller's basis — and the seller's already-depreciated balance sheet.

The number that matters: on a $4M asset purchase with roughly $1M allocable to short-life equipment and roughly $2M to amortizable intangibles, the first-year depreciation and §197 amortization stack can shelter six figures of taxable income. Miss the allocation in the LOI and you're stuck with whatever the IRS reads off the Form 8594 you both filed.

6. Not running the working capital true-up on time

Almost every acquisition agreement includes a working capital target and a post-close true-up window — usually 60 to 90 days. The buyer reconciles actual closing-date working capital against the agreed peg and any shortfall (or surplus) is paid between the parties.

It's in the contract. It's almost never on the operator's calendar.

Miss the window and you lose the leverage. A seller who left $80K of stale AR on the closing balance sheet and a $40K accrual you didn't book gets to keep both. That's $120K of working capital you bought and won't recover.

Calendar the true-up the day after the close. Pull the closing balance sheet in week two. Have the working capital calculation ready before the deadline, not on it.

What changes when an operator has done this before

The first 90 days don't have to be a scramble. They look like this when they're run by someone who's seen the playbook:

• A 30-day chart-of-accounts rebuild and a baseline monthly close.
• A covenant calendar and a banker who hears from you before they have to ask.
• A registration audit and clean multi-state payroll by the second pay run.
• A deal-structure memo on the wall — basis, depreciation, election status — that nobody has to recreate at tax time.
• A working capital true-up filed early.

That's it. None of it requires brilliance. It requires someone whose job is the post-close transition, not someone trying to fit it into the gaps between operating the business.

Find a CPA who knows what changes after the close

If you're 60 days from closing or 60 days past it, the playbook above is what separates a clean transition from a year of cleanup. System Six works with acquisition entrepreneurs and search fund operators specifically — the post-close chart-of-accounts rebuild, the SBA covenant reporting, the multi-state payroll cleanup are what they do every week, not once.

Read what their actual operator clients say on Sam's List and book an intro call before your next 90-day window starts. The mistakes above are cheap to prevent and expensive to inherit.
