How to Use runSDE to Underwrite Small-Business Deals Faster

Small-business acquisitions move quickly. A promising listing can attract multiple buyers, lenders may ask for additional documentation, sellers often want proof that a buyer is serious, and underwriting delays can cause a strong opportunity to slip away.

At the same time, speed cannot come at the expense of discipline. A buyer still needs to understand the company’s financial performance, normalize earnings, identify risks, compare deal structures, and decide whether the purchase price makes sense.

That is where a structured underwriting platform can help.

runSDE is designed to help buyers, advisors, and acquisition entrepreneurs evaluate small-business opportunities more efficiently. By organizing financial inputs, analyzing seller’s discretionary earnings, surfacing potential risks, and creating deal summaries, the platform can reduce the time spent on manual spreadsheet work and help buyers focus on the decisions that matter most.

This guide explains how to use runSDE to move from initial deal review to a more confident underwriting decision.

Why Faster Underwriting Matters in Small-Business Acquisitions

In the small-business acquisition market, speed and quality both matter.

A buyer who moves too slowly may lose access to attractive deals. A buyer who moves too quickly without proper diligence may overpay, misunderstand the cash flow, or inherit risks that were visible before closing.

The underwriting process helps answer several essential questions:

Is the business actually profitable?
Are the seller’s earnings claims supported by documentation?
What is the normalized seller’s discretionary earnings?
Does the purchase price make sense?
Can the business support debt service?
What risks could affect performance after closing?
What additional information should the buyer request?
Is this opportunity worth pursuing further?

Traditional underwriting can involve scattered documents, manual calculations, disconnected spreadsheets, email threads, and inconsistent assumptions from deal to deal. runSDE helps streamline that process by giving buyers a more organized way to evaluate financials and compare opportunities.

The result is not just faster underwriting. It is a more repeatable acquisition workflow.

Step 1: Create Your runSDE Account and Buyer Profile

The first step is to create an account and set up your profile. This gives the platform basic context about your acquisition goals, buyer background, and financial criteria.

A strong profile can help organize your activity around the types of deals you actually want to review. For example, a buyer targeting service businesses with stable cash flow may underwrite opportunities differently than a buyer focused on retail, restaurants, online businesses, or local home services.

When setting up your profile, consider adding information such as:

Target industry or business type
Preferred deal size
Available down payment capital
Financing preferences
Geographic focus
Experience level
Acquisition timeline
Risk tolerance
Desired owner involvement

This step may seem basic, but it matters. The more clearly you define your acquisition criteria, the easier it becomes to filter opportunities and avoid spending time on deals that do not fit your goals.

A buyer who knows what they are looking for can move faster without becoming careless.

Step 2: Get Comfortable With the Dashboard

Once your account is active, spend time exploring the dashboard. This is where you will manage deal information, review financial inputs, compare opportunities, and access underwriting outputs.

A well-organized dashboard can become the center of your acquisition workflow. Instead of tracking every opportunity across separate folders, emails, spreadsheets, and notes, you can use the platform to keep key deal information in one place.

Common dashboard areas may include:

Deal pipeline: A place to track active, rejected, and priority opportunities
Financial analysis tools: Inputs and models for reviewing revenue, expenses, SDE, debt service, and valuation
Reports: Summaries that can be shared with partners, lenders, or advisors
Comparison views: Side-by-side analysis of multiple acquisition targets
Resources or support: Guidance for understanding underwriting concepts and platform features

Before uploading deal data, it is helpful to understand how the platform organizes information. That way, once you begin underwriting an actual business, you can move through the process more efficiently.

Step 3: Gather the Right Documents Before Inputting Data

The quality of your underwriting depends on the quality of the information you provide. Before entering financial data into runSDE, collect as much supporting documentation as possible from the seller or broker.

At the initial stage, you may not receive every document. That is normal. But even a preliminary review should be based on more than a short listing description or seller summary.

Useful documents may include:

Profit and loss statements
Tax returns
Balance sheets
Bank statements
Payroll records
Sales reports
Accounts receivable aging
Accounts payable aging
Debt schedules
Equipment lists
Lease agreements
Inventory reports
Customer concentration details
Owner add-back explanations

For small businesses, seller-provided financials can vary widely in quality. Some businesses have clean books and professional accounting records. Others rely on informal bookkeeping, inconsistent categorization, or owner-managed spreadsheets.

runSDE can help organize the analysis, but buyers still need to verify that the source information is credible.

Step 4: Input Core Financial Data

After gathering the relevant documents, begin entering the financial data for the business you are evaluating.

The most important starting inputs typically include:

Annual revenue
Cost of goods sold
Gross profit
Operating expenses
Payroll expense
Rent or lease expense
Owner compensation
Seller’s discretionary earnings
Debt obligations
Asset values
Inventory value
Working-capital needs

When entering data, accuracy is essential. A small mistake in revenue, payroll, rent, or owner add-backs can materially change the underwriting result.

Buyers should pay special attention to seller’s discretionary earnings, often called SDE. SDE is commonly used in small-business acquisitions because it estimates the total economic benefit available to one full-time owner-operator. However, SDE can be overstated if the seller adds back expenses that are not truly discretionary, personal, or nonrecurring.

For example, a seller may add back:

Personal vehicle expenses
Travel and meals
Family-member payroll
One-time repairs
Owner salary
Legal or professional fees
Nonessential subscriptions
Discretionary benefits

Some add-backs may be valid. Others may be questionable. A buyer should review each adjustment carefully rather than accepting the final SDE figure at face value.

Step 5: Normalize Seller’s Discretionary Earnings

One of the most important parts of deal underwriting is normalizing earnings.

A business may be advertised with a certain SDE figure, but that number must be tested. The buyer needs to understand what the business is likely to produce under new ownership, not just what the seller claims it produced historically.

runSDE can help buyers organize the process of reviewing, adjusting, and documenting SDE assumptions.

When normalizing SDE, consider questions such as:

Is the owner currently working full time in the business?
Would the buyer need to replace the owner with a paid manager?
Are all payroll expenses properly included?
Are any personal expenses being added back?
Are those add-backs documented?
Are one-time expenses truly nonrecurring?
Are there underreported or missing expenses?
Have margins changed over time?
Are revenue trends stable, growing, or declining?

The goal is not to create the most favorable number. The goal is to create the most realistic number.

A deal that looks attractive at $250,000 of SDE may look far less compelling if normalized SDE is closer to $175,000. That difference can affect valuation, financing, debt service, buyer compensation, and negotiation strategy.

Step 6: Use AI-Powered Insights to Identify Risks

After the financial data is entered, runSDE can help analyze the information and surface insights that may deserve closer attention.

This is where technology can be especially useful. Instead of manually scanning every line item or rebuilding models from scratch, buyers can use AI-powered analysis to identify patterns, inconsistencies, and potential red flags.

Common risk areas may include:

Declining revenue
Rising expenses
Shrinking gross margins
Customer concentration
High owner dependency
Weak cash flow
Unclear add-backs
Large debt obligations
Unusual expense trends
Inconsistent profitability
Heavy working-capital needs
Seasonality
Lease or location risk
Technology or systems gaps

AI-powered insights should not replace buyer judgment or professional advice. Instead, they should help buyers ask better questions faster.

For example, if the platform flags declining margins, the buyer can investigate whether the cause is supplier cost increases, pricing pressure, waste, labor inefficiency, discounting, or accounting errors. If customer concentration appears high, the buyer can request customer-level revenue reports and contract details.

Good underwriting is not just about receiving answers. It is about knowing which questions to ask next.

Step 7: Review Valuation Estimates

Once the normalized financials are clearer, the next step is valuation.

Small businesses are often valued based on a multiple of SDE or EBITDA, depending on size, industry, management structure, and buyer type. Smaller owner-operated businesses are commonly evaluated using SDE, while larger businesses with management teams may be assessed using EBITDA.

runSDE can help buyers compare the asking price against the company’s earnings profile and risk level.

When reviewing valuation, consider:

The stated asking price
Normalized SDE
Implied SDE multiple
Industry norms
Revenue trends
Customer concentration
Management depth
Asset value
Growth potential
Required capital investment
Financing terms
Buyer’s target return

A low multiple does not automatically mean a good deal. Sometimes a business is cheap because it is declining, poorly documented, overly dependent on the seller, or exposed to major risks.

Likewise, a higher multiple may be justified if the business has recurring revenue, strong margins, durable customer relationships, clean financials, reliable management, and clear growth opportunities.

Valuation should reflect both performance and risk.

Step 8: Test Financing and Debt Service

A deal can look attractive from a valuation standpoint but still fail as a financed acquisition if the business cannot comfortably support debt service.

Buyers should evaluate whether the business produces enough cash flow to cover:

Loan payments
Buyer compensation
Taxes
Working capital
Maintenance expenses
Growth investments
Emergency reserves

This is especially important for buyers using SBA financing or other acquisition debt. Lenders will evaluate the company’s historical cash flow, buyer contribution, collateral, industry risk, and debt service coverage. But buyers should conduct their own analysis as well.

A responsible underwriting process should include downside scenarios.

For example:

What if revenue falls by 10 percent?
What if gross margin declines?
What if payroll costs increase?
What if a key customer leaves?
What if the buyer must hire a manager?
What if the business needs new equipment?
What if the first six months are slower than expected?

runSDE can help buyers evaluate whether the deal still works under conservative assumptions. If the transaction only makes sense under the seller’s best-case version of the future, the buyer should be cautious.

Step 9: Compare Multiple Deals Side by Side

One of the biggest advantages of using a structured underwriting platform is the ability to compare opportunities consistently.

Many buyers evaluate deals one at a time and become emotionally attached to whichever opportunity is currently in front of them. That can lead to rushed decisions or weak negotiation discipline.

By analyzing multiple deals using the same framework, buyers can better understand which opportunities actually fit their goals.

A side-by-side comparison may include:

Asking price
Revenue
SDE
Implied multiple
Revenue trend
Margin trend
Debt service coverage
Customer concentration
Seller financing availability
Industry risk
Required buyer involvement
Growth opportunities
Key diligence concerns

This type of comparison helps buyers separate “interesting” deals from truly strong acquisition candidates.

For example, one business may have higher SDE but also higher customer concentration and weaker documentation. Another may have lower current earnings but more stable recurring revenue and better systems. A structured comparison makes those tradeoffs easier to evaluate.

Step 10: Collaborate With Advisors

Even with strong software tools, buyers should not underwrite complex acquisitions alone.

Attorneys, accountants, lenders, brokers, and acquisition advisors can all provide valuable perspective. runSDE can support collaboration by giving advisors a clearer view of the buyer’s assumptions, financial inputs, and risk analysis.

Advisors may help with:

Quality of earnings review
Tax return analysis
Deal structure
SBA loan readiness
Legal due diligence
Lease review
Asset purchase agreements
Working-capital requirements
Transition planning
Seller note terms
Closing conditions

Collaboration is especially valuable when a deal becomes more complex. For example, if the seller is offering partial financing, if there are multiple owners, if the business has unusual add-backs, or if customer concentration is high, advisor input can help prevent costly mistakes.

A good platform can organize the data. Good advisors can help interpret what the data means.

Step 11: Generate Reports for Decision-Making

Once the deal has been analyzed, buyers often need to communicate their findings to lenders, investors, partners, or internal stakeholders.

runSDE can help generate reports that summarize the underwriting work in a clear and organized format. These reports can be useful for documenting assumptions, preparing financing conversations, and supporting negotiation strategy.

A strong underwriting report may include:

Business overview
Revenue and earnings summary
SDE adjustments
Valuation estimate
Financing assumptions
Debt service analysis
Risk assessment
Key diligence questions
Deal strengths
Deal concerns
Recommended next steps

Reports are also useful for maintaining discipline. When a buyer writes down the assumptions behind a deal, it becomes easier to identify gaps, challenge optimism, and compare the opportunity against other deals.

A clear report can also improve communication with lenders. Instead of presenting a vague opinion that the business “looks good,” the buyer can show how they evaluated cash flow, risks, and debt service capacity.

Step 12: Use the Analysis to Negotiate Smarter

Underwriting is not only about deciding whether to buy. It is also about deciding how to buy.

The insights from runSDE can support a more informed negotiation strategy. If the platform highlights weak documentation, declining revenue, customer concentration, or questionable add-backs, the buyer may have a basis to adjust the offer or request different terms.

Possible negotiation responses include:

Lowering the purchase price
Requesting seller financing
Adding an earnout
Requiring a transition period
Asking for customer introductions
Creating a holdback
Adjusting working-capital requirements
Requiring updated financials before closing
Adding contingencies tied to lender approval or lease assignment

A buyer should not treat risk as a reason to panic. Risk is part of every acquisition. The question is whether the risk is properly reflected in the deal structure.

A well-underwritten deal gives the buyer more confidence at the negotiation table because the offer is tied to facts rather than emotion.

Step 13: Prepare for Post-Closing Execution

A common mistake is treating underwriting as something that ends at closing. In reality, the best underwriting process also helps shape the post-closing plan.

If the analysis reveals weak margins, the buyer should plan how to improve pricing, purchasing, labor scheduling, or waste. If customer concentration is high, the buyer should prioritize relationship management. If financial reporting is poor, the buyer should upgrade accounting systems quickly. If the business depends heavily on the seller, the transition plan should focus on knowledge transfer.

The underwriting process should inform the first 30, 60, and 90 days after closing.

Important post-closing priorities may include:

Communicating with employees
Meeting key customers
Stabilizing vendor relationships
Reviewing cash flow weekly
Tracking actual results against underwriting assumptions
Confirming access to systems and accounts
Preserving what already works
Delaying unnecessary changes
Building a reporting cadence
Addressing urgent operational risks

A buyer who understands the risks before closing is better prepared to manage them after closing.

Common Mistakes to Avoid When Using Underwriting Software

runSDE can help accelerate analysis, but the buyer still needs to use the platform thoughtfully. Software is most powerful when paired with disciplined judgment.

Avoid these common mistakes:

Relying on Seller Numbers Without Verification

A seller’s financial summary is a starting point, not a conclusion. Always compare seller-provided numbers against source documents when available.

Treating AI Output as Final Advice

AI-powered insights can help identify issues and organize analysis, but buyers should still involve professional advisors for legal, tax, financing, and accounting matters.

Ignoring Qualitative Risks

Not every risk appears in the financial statements. Key-person dependency, culture, customer loyalty, lease terms, and operational complexity can all affect the success of the acquisition.

Comparing Deals With Different Assumptions

If one deal is underwritten aggressively and another conservatively, the comparison becomes misleading. Use consistent assumptions across opportunities.

Forgetting About Working Capital

A business may generate profit but still require cash to operate. Buyers should avoid using all available capital for the purchase price and closing costs.

Moving Forward Without a Transition Plan

A deal can be well-underwritten financially and still struggle operationally if the buyer does not manage the transition carefully.

The Real Benefit of runSDE: Better Decisions, Faster

The value of runSDE is not just that it can help buyers move faster. The deeper benefit is that it can help buyers make decisions with more structure, consistency, and confidence.

In a competitive acquisition market, buyers need to review opportunities efficiently. But they also need to avoid overpaying, misunderstanding earnings, or overlooking risks that could affect performance after closing.

A good underwriting workflow helps buyers:

Save time on repetitive analysis
Organize financial data
Normalize earnings
Identify risk areas
Compare multiple deals
Collaborate with advisors
Prepare lender conversations
Support negotiations
Build a stronger post-closing plan

The platform can help turn scattered deal information into a clearer decision-making process.

Conclusion: Faster Underwriting Should Still Be Disciplined Underwriting

Small-business acquisitions require both speed and caution. A buyer who takes too long may miss strong opportunities, but a buyer who skips diligence may inherit problems that were visible before closing.

runSDE can help buyers accelerate the underwriting process by organizing deal information, analyzing financials, identifying risks, comparing opportunities, and generating useful reports. For acquisition entrepreneurs, searchers, advisors, and investors, that structure can make the difference between reactive deal review and disciplined decision-making.

The best buyers do not simply chase deals. They evaluate them carefully, compare them consistently, and negotiate from a position of knowledge.

Using runSDE can make that process faster, clearer, and more repeatable.

In business acquisitions, the goal is not just to close more deals. The goal is to close the right deals with a clear understanding of the numbers, risks, and opportunities behind them.
