Financial due diligence and quality of earnings for software and tech deals

Greywood CPA performs financial due diligence for buyers and investors in software and technology companies, and sell-side readiness work for founders preparing to sell. Due diligence is not an audit: it focuses on the quality and sustainability of earnings, how much working capital the business needs and what liabilities a buyer would inherit.

In software deals the biggest questions are usually revenue quality (recurring vs. one-time, churn and concentration), how deferred revenue is treated in the price, and sales tax exposure in states where SaaS is taxable.

What a quality of earnings review covers

  • Adjusted EBITDA: removing one-time items and owner expenses, and adding costs a buyer will incur
  • Revenue quality: recurring vs. non-recurring, churn, expansion and customer concentration
  • Proof of revenue and cash: billing and cash receipts tied to reported revenue
  • Cost structure: capitalized software, contractors vs. employees, hosting costs

Working capital and the deferred revenue question

Purchase agreements usually set a normal level of working capital (the "peg"), and the price adjusts if the business delivers more or less at closing. In software, deferred revenue is often the largest liability. Whether it counts in working capital, or as debt-like, can move the price significantly, so it needs analysis, not assumptions.

Sales tax exposure for SaaS

Some states tax SaaS and digital products and others don't, and economic nexus means sellers can owe tax in states where they have no office. Uncollected sales tax is a common liability buyers discover in diligence. We estimate exposure by state so it can be handled through price, escrow or a voluntary disclosure.

Sell-side readiness for founders

  • A sell-side quality of earnings so you know the numbers before the buyer does
  • Clean revenue and deferred revenue schedules
  • Sales tax and payroll tax exposure identified and fixed early

Tech due diligence FAQs

What is the difference between due diligence and an audit?

An audit gives an opinion on financial statements under auditing standards. Due diligence analyzes the quality and sustainability of earnings, working capital and liabilities for a specific transaction, and doesn't express an opinion.

What is adjusted EBITDA in a quality of earnings report?

Reported EBITDA adjusted for one-time items, owner-related expenses and costs a buyer will incur after closing, so it reflects the business's sustainable earnings.

How is deferred revenue treated in a software deal?

It depends on the purchase agreement. It may be included in working capital or treated as a debt-like item that reduces the price. The treatment can be worth a lot, so it should be analyzed and negotiated.

Can SaaS companies owe sales tax?

Yes. Some states tax SaaS, and economic nexus can create obligations without a physical presence. Uncollected sales tax is a common diligence finding.

How do your fees work?

We quote one fixed fee in writing before any work starts, based on deal size, the number of entities and the timeline.
