How Can Intermediation Be Distinguished From the Underlying Service?

In ISIC Rev. 5, published by the UN Statistics Division, the distinguishing question is simple to state and harder to apply in mixed businesses. If business A arranges a service and business B supplies it, A is the intermediary and B is the provider. The customer may pay through one website or one invoice, but the classification follows the work performed, not the payment route.

Who answers when the service itself goes wrong?

Start with responsibility. When a booked room is not ready, a meal never arrives, or a scheduled visit is cancelled, someone has to fix it, apologise, rebook, or refund. That someone is usually the supplier, because the supplier controls the staff, the premises, and the timetable. The intermediary may pass the message on, chase an answer, or offer an alternative, yet it cannot open another room, cook another meal, or send another carer through the door. That gap between passing a message and fixing the underlying problem is a practical way to see the boundary. Job titles and website slogans blur it, but a short description of a bad day at work tends to sharpen it again: who was expected to put the service right, and with what resources?

What would the business still have to sell if its partners disappeared overnight?

Imagine every hotel, driver, or care provider on a platform stopped trading tomorrow. What could the platform still offer a customer the next morning? An arranging business would be left with its search tools, its lists, its booking know-how, and its relationships, but it would have no room, ride, or care visit to sell. A supplying business in the same position would still hold its own rooms, vehicles, or staff, even if its bookings dried up. This thought experiment is not a formal rule in ISIC Rev. 5, published by the UN Statistics Division. It is a way of forcing a plain description of the work, before any heading is consulted, so the description is honest about what is actually produced.

Revenue language can support that description, though it never settles the matter alone. A fee charged for making a match, a commission paid when a booking completes, or a subscription for access to a marketplace all point toward arranging as the product sold. A price charged for a night, a journey, or an hour of care points the other way. Mixed income streams need care: a business can earn both kinds of money, and in that case the split of its work matters more than the label on any single invoice. Notes, contracts, and day to day tasks usually reveal that split better than a homepage does.

Why does a hotel booking make the split easy to see?

Take the travel platform example already used in this area. A guest searches, picks a hotel, pays through the platform, and later sleeps in a room the hotel owns and staffs. The platform’s staff never made the bed, checked the guest in at the desk, or fixed the shower. Their work was search, presentation, availability, payment handling, and confirmation. The hotel’s staff did the rest. Two businesses, two payrolls, two sets of daily tasks, one guest journey. Splitting the journey at the point where arranging stops and delivery starts is the whole skill this guide is trying to teach.

Where does a business that both books and hosts sit?

Some businesses genuinely do both. A company might run its own small hotel while also booking guests into other hotels, or employ its own carers while also matching families with independent carers. No single sentence in a guide can sort such a business, because the answer turns on which activity dominates its work overall. That dominance question is known as a principal activity assessment, and it belongs to the record holder, not to this guide. What a reader can do here is describe each strand separately, estimate how much of the business’s effort each strand takes, and keep those descriptions apart instead of merging them into one vague label.

What order of checks keeps the two roles apart?

Work through the UNSD Rev. 5 classification detail and the Rev. 5 publication listed in the frontmatter, reading full class descriptions rather than titles alone. Titles are short summaries; inclusions and exclusions inside the description do the real sorting. Compare each strand of work, arranging and supplying separately, against those descriptions. Then look at national guidance, which may give local examples for mixed businesses. Where a formal entry is involved, the national statistical institute or business register that holds the record is the place to confirm it.

For this guide, that last point is also the closing boundary. This is statistical classification only, and it offers a way of describing arranging work versus supplying work so readers can compare like with like. It does not settle any individual business’s code, its main activity, or its registration, and any formal question of that kind belongs with the national statistical institute or business register that holds the record.
