Your First 90 Days

1. The Reality of Buying a Business

Buying a business is one of the most powerful wealth-building moves available to an individual or institution. You bypass the startup grind, inherit revenue, customers, and systems — and if you buy right, the business can pay for itself within a few years.

But the failure rate among first-time buyers is high. Not because they lack capital or ambition, but because they underestimate the complexity of the deal itself: finding the right business, paying the right price, financing correctly, and surviving due diligence without losing a deal that should close.

60–70%

of business buyers either fail to close a deal or overpay significantly. The difference between a successful acquisition and a costly mistake usually comes down to preparation and experienced guidance.

This guide is written for serious buyers: individuals pursuing entrepreneurship through acquisition (ETA), search fund operators, private equity professionals entering the lower middle market, and strategic acquirers. We cover the full journey — from identifying your buyer profile to running your first 90 days post-close.

If you're ready to get started, our team can walk you through what's currently available in your target industry and size range — confidentially, with no obligation.

2. What Type of Buyer Are You?

Not all buyers want the same thing — and sellers can smell it when a buyer hasn't defined their own thesis. Before you look at a single listing, you need to know who you are as a buyer: what size deal you're targeting, what you're willing to pay, and what you expect from ownership.

Individual Owner-Operator

Most Common

You want to buy a job you love — but with equity upside. You'll run the business day-to-day and plan to grow it before an eventual exit.

First-time buyer replacing employment income

Typically $500K–$5M deal range

SBA financing common

Owner transition period expected

Best For: Service businesses, professional practices, retail, trades

Search Fund / ETA Operator

Growing Fast

You've raised committed capital from investors and are executing a structured search for a single acquisition. Speed, discipline, and deal sourcing are your key variables.

Backed by institutional or individual investors

2–4 year search horizon

Deals typically $3M–$30M

Management transition built in

Best For: Recurring revenue businesses, B2B services, light manufacturing

Private Equity / Family Office

Institutional

You're deploying capital at scale, building a platform, or executing a buy-and-build strategy. Deal volume, pipeline, and leverage discipline are central.

Multiple acquisitions per year

Management team in place or added

Leverage-optimized financing

Hold period of 3–7 years

Best For: Fragmented industries, bolt-on targets, platform businesses

Strategic Acquirer

Synergy-Driven

You're buying to expand market share, acquire talent or technology, or enter a new geography. You can pay more than financial buyers because of synergies you can actually realize.

Paying strategic premium (1–2x more)

Integration timeline matters

Cultural fit is a real deal risk

Faster due diligence expectations

Best For: Competitors, adjacent verticals, supplier/distribution channel

3. Finding the Right Business

Most buyers spend months searching and then rush the diligence. The real skill is sourcing: finding a business worth buying before it hits the public market — or identifying one in a crowd of mediocre listings that others have overlooked.

Where Deals Come From
On-market listings

BizBuySell, DealStream, industry marketplaces. High volume, high competition. You're seeing what every other buyer is seeing. Expect asking prices to reflect that.

Business broker relationships

If you build real relationships with active brokers in your target sector, you get the call before the CIM goes out. Most closed deals in the lower middle market never hit public listings.

Proprietary outreach

Identify businesses you want to own — then reach out directly. This is how PE firms and serious searchers source their best deals. It requires more work but produces far better terms.

Advisor networks

M&A advisors like Mettle work both sides of the market. They know which sellers are thinking about a transition — sometimes 12–24 months before a formal process begins.

Before you look at any deal, define your acquisition criteria in writing: industry, revenue range, EBITDA floor, geography, deal structure preferences, and what you absolutely won't buy. This saves months of wasted diligence on the wrong deals.

4. Valuation From a Buyer's Perspective

Sellers have a number in their head. Your job as a buyer is to figure out what the business is actually worth — not what someone hopes to sell it for. The good news: most asking prices in the lower middle market are negotiable when you come to the table with data.

SDE vs. EBITDA: Which Metric to Use

For businesses under $2–3M in revenue, sellers typically present Seller Discretionary Earnings (SDE) — net profit plus owner compensation plus personal expenses run through the business. As a buyer, you're paying a multiple of what you expect to earn.

Larger businesses are valued on EBITDA. This assumes a professional management layer and that the owner is replaceable. If you're paying on EBITDA, verify that a management team is actually in place — or price the cost of replacing the owner into your offer.

How to Stress-Test the Multiple

Add-back scrutiny: Question every add-back. One-time items, owner compensation, non-recurring expenses. Are these truly one-time? Would they recur under your ownership?

Customer concentration: If more than 20% of revenue comes from one customer, that's risk — and it should reduce your multiple. Buyers lose deals post-close when that customer leaves.

Revenue quality: Recurring revenue (contracts, subscriptions, retainers) warrants a higher multiple than project-based or one-time revenue. Price that difference explicitly.

Owner dependence: If the current owner is in every customer relationship, that business is worth less to you. Factor in the transition risk and the cost of replacing key relationships.

2x–4x SDE | 3x–7x EBITDA

These are typical ranges for lower middle market businesses. Where a specific deal falls depends on growth trajectory, industry, recurring revenue, and how badly the seller needs to transact. Knowing this range prevents you from overpaying — or walking from a deal that's actually priced right.

5. How to Finance an Acquisition

Most business acquisitions in the lower middle market are financed with a combination of sources. The structure matters as much as the price — how you finance determines your cash-on-cash return, your personal risk exposure, and whether the business can actually service the debt.

Financing Options Compared

Method
SBA 7(a) Loan
Conventional Bank Loan
Seller Financing
Search Fund / PE Equity
HELOC / Personal Capital
LTV / Equity
Up to 90%
50–70%
10–30%
30–50% equity

Rate
Prime + 2.75%
Prime + 1–3%
4–8%
N/A (equity)
Variable
Pros
Low down payment, long term (10–25 yr)
Faster than SBA, flexible structure
Signals seller confidence, improves total structure
No debt service in early years, aligned incentives
Fastest close, maximum flexibility
Cons
Slow process, personal guarantee required, seller note often needed
Higher equity requirement, strong DSCR needed
Subordinated to senior debt, note can conflict with bank covenants
Diluted ownership, investor governance, return expectations
Personal risk concentration, limited scale

The most common structure in SBA deals: 10% buyer equity, 80% SBA loan, 10% seller note. The seller note shows commitment and often satisfies the bank's requirement that the seller has skin in the game post-close.

Key rule: Make sure the business cash flow covers the total debt service with a 1.25x+ DSCR buffer. If the numbers don't work at the asking price with your financing structure, either negotiate the price down or walk.

6. Going to Market as a Buyer

Once you've identified a target, the process moves fast. Sellers and their advisors are evaluating multiple buyers simultaneously. Your ability to move quickly and credibly — with proof of funds and a clear thesis — is what gets you the deal.

How the Process Works

Sign NDA

Access CIM and financials

IOI

Indication of interest — non-binding price range

Management Meeting

Meet owner, verify key claims

LOI

Letter of intent — binding exclusivity, non-binding price

Due Diligence

30–60 days of verification

Close

Purchase agreement, wire, keys

Step 1: Sign the NDA and receive the CIM

A well-run process will have a Confidential Information Memorandum (CIM) ready for qualified buyers. This 20–40 page document covers financials, operations, team, and growth opportunity. Read it carefully before engaging.

Step 2: Buyer outreach

If the deal passes your initial screening, submit a non-binding IOI. This communicates your valuation range and deal structure intent. It's how you get a seat at the management meeting.

Step 3: Management meeting and site visit

This is where you evaluate the human side of the deal. Does the owner present well? Does the team seem capable? Is the business what the CIM says it is? This meeting often makes or breaks the deal on both sides.

Step 4: Submit your LOI

Your Letter of Intent includes price, structure, exclusivity period, and timing. Once signed, the seller stops talking to other buyers. You now have 30–60 days to diligence or renegotiate.

7. Due Diligence: What to Verify

Due diligence is where deals die — or close at a discount. The buyer who walks into diligence with a structured checklist and a clear thesis closes faster, negotiates better, and avoids post-close surprises. The buyer who wings it gets retrades or regrets.

Here's what experienced acquirers verify in every deal. This is not exhaustive — your deal may have industry-specific items. But this covers the ground that kills the most deals.

Market Approach

3 years of P&L statements and tax returns — reconcile them

Balance sheet: assets, liabilities, working capital

Accounts receivable aging — how collectible is it?

Cash flow bridge from EBITDA to actual distributions

Capital expenditure history and upcoming needs

Income Approach

Articles of incorporation and operating agreements

All customer and supplier contracts with assignment clauses

Pending or threatened litigation

IP ownership: patents, trademarks, proprietary software

Regulatory licenses, permits, environmental compliance

Operations

Org chart and key employee compensation / retention

Documented processes — what exists vs. what lives in the owner's head

Vendor and supplier concentrations and contract terms

Technology stack: owned vs. licensed, dependencies

Facility leases, renewal terms, and transfer clauses

Commercial

Top 10 customers: revenue, contract length, tenure

Churn and retention data (last 3 years)

Sales pipeline and forward-looking revenue visibility

Competitive landscape — why does this business win?

Pricing power and gross margin trajectory

The purpose of due diligence is not to kill the deal. It's to confirm your thesis or renegotiate based on what you find. Most deals that die in diligence die because the buyer finds something they should have asked about upfront — or because the seller wasn't prepared to answer.

8. Acquisition Timeline

The average acquisition in the lower middle market takes 6–9 months from first contact to close. That timeline can compress to 90 days for a well-prepared buyer with committed financing — or stretch to 18 months for a buyer who's searching without a clear thesis.

Typical Deal Timeline

Months 1–3 Search & Screening

Define criteria, build sourcing pipeline, engage advisor/broker relationships, review 20–30 CIMs. Expect to pass on 90%+ of what you see.

Month 3–4 Target Identification

Narrow to 2–3 active targets. Submit IOIs. Enter management meetings. Build financial models and preliminary offer thesis for each.

Month 4–5 LOI & Exclusivity

Select one deal. Negotiate and sign LOI. Engage legal, accounting, and QoE advisor. Begin diligence data room access immediately.

Months 5–6 Due Diligence

30–60 day structured diligence process. Financial, legal, commercial, operational. QoE report confirms or adjusts normalized earnings. Renegotiate if warranted.

Month 6–7 Definitive Agreement

Purchase agreement drafted and negotiated. Reps & warranties, indemnification, closing conditions. Financing confirmed. Board/investor approvals if applicable.

Month 7–8 Close & Transition

Wire transfers, title transfers, employee announcements. Transition period begins — typically 30–90 days with the seller. Your first 90 days starts now.

The most common delay point is financing — specifically SBA approval. If you're using an SBA loan, engage your lender at the LOI stage, not after diligence. SBA processing can add 4–8 weeks to any timeline.

9. Your First 90 Days

The wire has hit. The keys are yours. Most buyers vastly underestimate how disorienting — and how critical — the first 90 days are. You've just become responsible for every employee, every customer, and every vendor relationship. What you do (and don't do) in the first three months sets the tone for everything that follows.

"The biggest mistake new owners make is moving too fast. The business got to where it is doing something right. Your job in the first 30 days is to understand what that is — before you touch anything."

Here's how to approach your first 90 days as a new owner:

Days 1–30

Stabilize

Don't change anything. Observe first.

Meet every key employee individually

Introduction to top 10 customers by the former owner

Owner transition period exMap the actual cash cycle — where does money come from, when?pected

Identify the one or two people who actually run things day-to-day

Days 30–60

Understand

Shadow every department head for at least one day

Audit your largest customer relationships firsthand

Understand your vendor terms and renegotiation opportunities

Identify your 3 biggest risks and create a mitigation plan

Baseline all key metrics: revenue, margin, churn, pipeline

Build

Communicate your 90-day plan to the team — give them certainty

Make your first hires or structural changes with full information

Set your Year 1 OKRs and financial targets

Begin vendor and customer contract renegotiations if warranted

Establish reporting cadence: weekly team, monthly board/investors

The best acquirers come in with a plan but hold it loosely. What you learn in the first 30 days will reshape what you do in months 2 and 3. The ability to stay curious, stay present, and resist the urge to prove yourself is what separates successful buyer-operators from the ones who lose key people in the first quarter.
