Transition Period

A transition period (also called a training period or seller transition) is a post-closing arrangement in which the seller agrees to remain available to the buyer for a defined period — typically 30 days to 24 months — to transfer knowledge, introduce customers and key employees, assist with operational handover, and provide continuity during the ownership change.

The transition period is a key mechanism for protecting goodwill value in a business sale. Buyers pay for customer relationships, supplier arrangements, and operational knowledge — a seller who disappears immediately after closing takes much of that value with them. Longer transition periods (6–24 months) are common when the seller holds the primary customer relationships, manages proprietary technical processes, or is the face of the brand.

Transition terms are negotiated as part of the purchase agreement and specify the duration, compensation (if any — some transitions are included in the purchase price, others are compensated separately), geographic and time availability requirements, and what happens if the seller fails to fulfil their obligations.
