12-year-old digital product business with 18K+ PSD mockups, an 88% margin, and roughly 75% revenue growth.

The numbers: $264.5K annual revenue / $233.6K annual income, an 88% margin. At the $700K asking price, that works out to roughly 2.6x revenue and 3.0x income.

How it works: The business sells downloadable PSD mockups used by designers and agencies across apparel, packaging, billboards, and other products. The 18,000+ file catalog sells through the company's WordPress site and two additional marketplaces.

The seller situation: The two partners have worked together for more than 20 years and are stepping away after running this business for 12 years. For a business this old, I would want the longest P&L history available rather than underwriting it mainly on the recent growth period.

Worth asking: What specifically drove the roughly 75% revenue growth, and how much of the current revenue depends on a small number of marketplace channels or search rankings?
