How can a vendor loan or deferred consideration bridge a valuation gap between a PE buyer and a seller?

When the seller's price expectation exceeds what the buyer will pay upfront, structure can bridge the gap without the buyer overpaying in cash. A vendor loan has the seller finance part of the price — the buyer pays the rest later with interest — which reduces the day-one equity check and signals seller confidence; it usually ranks behind the bank debt, so it's quasi-equity from the lenders' view and can help leverage. Deferred consideration (or an earn-out) ties part of the price to future performance, shifting risk to the seller and aligning them with the forecast they're selling on. For the PE buyer these tools lower upfront capital (helping IRR), provide downside protection if the business underperforms, and keep the seller invested in the transition. The trade-offs are negotiating complexity, security/ranking, and disputes over earn-out measurement.
