What SDE is

Seller discretionary earnings, or SDE, is often used in SMB acquisition analysis to estimate owner-benefit cash flow before financing.

It can be useful, but it is not proof. SDE is only as strong as the financials, adjustments, and support behind it.

Why add-backs matter

Add-backs can change the entire deal. A business that looks average on reported earnings can look attractive after adjustments.

That is exactly why buyers need an SDE sanity check. Adjusted SDE can make a weak deal look stronger than it is.

Common add-back problems

Some add-backs are reasonable. Others are wishful thinking. The buyer has to separate personal expenses, true one-time costs, market-rate replacement costs, owner compensation, and expenses that will continue after close.

A weak add-back does more than inflate earnings. It can also inflate debt support, buyer confidence, and the price a buyer is willing to defend.

Worked example: $750,000 of claimed SDE can become $560,000

Assume a listing starts with $600,000 of reported SDE and adds back $150,000 of seller expenses. The headline adjusted SDE becomes $750,000.

If outside review supports only $80,000 of those adjustments and the buyer needs $120,000 of replacement management, the practical cash-flow starting point becomes $560,000: $600,000 plus $80,000, less $120,000. That $190,000 difference can materially change DSCR, financing support, and the price a buyer can defend.

  • Reported SDE: $600,000
  • Supported add-backs: $80,000
  • Replacement management: $120,000
  • Buyer cash-flow basis: $560,000

Seller-provided vs lender-reviewed add-backs

A seller or broker can present add-backs in a CIM, teaser, or listing. That does not mean a lender, CPA, or diligence provider will accept them.

Lender-reviewed add-backs matter because debt support depends on adjustments that can survive outside review. See how those adjustments affect SBA cash flow and DSCR supportability.

How ADE flags SDE quality and add-back risk

ADE looks for signals that reported earnings, SDE, adjusted EBITDA, and add-backs need more support before the buyer trusts the output.

It can flag weak financial quality, unsupported adjustments, lender-readiness gaps, and situations where a deal only works after aggressive assumptions.

What still needs CPA and lender review

ADE is not a CPA, lender, QoE provider, or diligence report. It helps the buyer identify pressure points before LOI.

A serious buyer still needs accounting review, lender review, source documents, tax returns, bank statements, and judgment before relying on adjusted earnings.

ADE is decision-support software. It is not a lender, valuation firm, CPA, attorney, broker, or diligence provider, and it does not provide legal, tax, accounting, lending, valuation, investment, or acquisition advice.
