Ancillary service is a term used to describe a supplementary service that supports the delivery of a primary product or service. These services are typically optional or add-ons that enhance value, convenience, or quality for customers. The concept is widely used across industries and can encompass professional, logistical, or operational support.

In healthcare, ancillary services are supportive medical services that accompany core treatment. Common examples include diagnostic imaging (such as X-ray or MRI), laboratory testing, physical and occupational therapy, medical transportation, and pharmacy or supply services within a hospital or clinic setting.

In travel and hospitality, ancillary services are add-ons that accompany the base product. Airlines offer baggage handling, seat selection, priority boarding, on-board meals, and Wi-Fi, while hotels may provide airport transfers, spa or wellness services, tours, or late checkout.

In business and technology, ancillary services may include installation, maintenance, training, consulting, or data analytics that accompany a primary product. Ancillary revenue streams are often pursued through unbundling or bundling arrangements, pricing strategies, and targeted marketing.

The term derives from ancillary, meaning serving to assist. The scope and regulation of ancillary services vary by industry and jurisdiction, and markets increasingly include digital, on-demand, or platform-based ancillary offerings alongside traditional core products.
