Your private ownership business plan must survive both phases. Many business owners focus only on the first review. The second phase is where most deals die due to inadequate documentation. Why does this happen? Poor preparation kills more deals than bad numbers. For your private ownership business plan, this step matters most.

Financial due diligence centers on quality of earnings as a key investment criterion. This means PE firms don't just look at income figures in your private ownership business plan.

They look at recurring vs. one-time income sources. They examine profit margins by product line or service category. They verify that earnings estimates in your private ownership business plan reflect sustainable business models.

PE firms dig deep into your customer relationships and contracts. They want to see customer retention rates, average contract lengths. Renewal percentages in your private ownership business plan.

In the lower middle market, roll-ups make up over 80% of all transactions. Your private ownership business plan should position your company as either a platform for future buys or a planned add-on.

If you're positioning as a platform, include detailed buy criteria and integration capabilities. Show how you can absorb smaller rivals or complementary businesses.

If you're an add-on candidate, clearly articulate your unique value proposition within broader industry consolidation plans. Your private ownership business plan should make the planned fit obvious to potential acquirers. What makes you the missing puzzle piece?

PE firms check cultural fit between your company and their existing portfolio companies. Your private ownership business plan should address management styles, company values, and employee satisfaction metrics.
