Corporate gifts in Paris: a client at Orly, a partner's office, the team
Not all corporate gifts in Paris go to an office: at Charles de Gaulle or Orly a courier can wait at the exit with a name card, by arrangement, once the route and the price are confirmed before payment. The right format then depends on where the gift changes hands: at the terminal exit, at a reception desk, or on each colleague's desk. It also depends on who is receiving it — a visiting client, a partner, or a whole team.
Met at Orly or Charles de Gaulle: a gift for a visiting client
Flowers for a visiting client don't have to wait until the office: both Paris airports take corporate orders by request. At Charles de Gaulle and at Orly the courier checks the route and confirms the price before payment, then waits with a name card so the guest can be met at the arrivals exit.
A guest wheeling a cabin case has one hand free, and that decides the format. The 25 Mixed Roses in a Box is one option, or a smaller hand-tied bouquet if someone else is there to hold it. Either way, the choice comes down to how much the guest can carry, not which looks more impressive.
When the itinerary runs straight from the airport to a hotel, the gift follows the same route. The hotel decides whether it goes up to the room or waits at reception. The order needs the surname the guest checked in under, plus the room number if it's known.

A partner's office in Paris: roses in a box or a basket for the meeting room
An office delivery in Paris needs the company's name and the floor, since reception staff rarely know every tenant in the building by name. Where the building runs access control, the gift is left at reception, and the sender gets a message naming whoever signed for it.
The format follows the setting. A box of roses suits a director's desk, while a gift basket of cheese, fruit or sweets suits a meeting room, set straight on the table with no vase needed.
French custom favours an odd number of stems in a bouquet, and chrysanthemums are kept out of gifts entirely — more on that under French flower etiquette. One more thing worth checking before ordering: La Défense, the business district across the river in Puteaux, sits outside the standard delivery zones. An address there can still be arranged for corporate gift delivery in Paris, but the route and price are confirmed before payment. Zones and terms are on the delivery page.
Spray roses or dianthus for every name on the staff list
Sending the same gift to everyone on a staff list calls for small bouquets made to one sample, rather than the kind built for a single desk. The 11 Lavender Spray Roses works at that scale, and so does the 15 Dianthus. Both can be ordered as small bouquets made to one sample.
One order can carry bouquets bound for several addresses at once, though delivery is counted separately for each address rather than once for the whole batch. The card is free with every order, so each bouquet can still carry its own name even when the flowers themselves are all the same.
Before the courier sets off, the florist sends a photo of the finished bouquets, and the sample can still be adjusted at that point if something needs changing. For the paperwork: an invoice can be raised to the company, payment taken by bank transfer, and closing documents issued on request; a running arrangement is covered by a contract.

Where to start depends on who the gift is for: roses in a box suit a single desk, gift baskets suit a shared table, and a plain stem count from roses covers everything in between.
