A corporate opening is an event with high image stakes, high media exposure and high protocol expectations. You invite your premium clients, your strategic partners, your staff, the press, local elected officials and sometimes the institutions. It is one of the rare moments when these varied audiences come together in the same place and look at your company as a whole.

This guide covers the entire process of organising a professional opening, from defining the brief to media post-production. It is aimed at communications departments, managing directors, secretaries-general and event managers who take charge of this kind of milestone.

The method presented here comes from organising 80+ openings since 2018, ranging from a shop opening to the opening of a 50-hectare industrial site with a government minister present.

1. Defining the objective: why hold an opening?

Every opening serves one main objective. Identifying this objective is the first step, because it determines all the choices that follow (capacity, venue, programme, audience, budget).

Objective 1: marking a strategic milestone. You are opening a new head office, a new factory, a new site that marks a major transformation of your company. The opening celebrates this milestone and launches the new phase. Audience: premium clients, strategic partners, press, local elected officials. Format: protocol ceremony + reception.

Objective 2: building local awareness. You are opening a site in a new town and you want to become known. The opening brings together elected officials, the regional press and the local economic ecosystem. Audience: elected officials, Chamber of Commerce, professional bodies, regional press. Format: ceremony + site tour + reception.

Objective 3: demonstrating your industrial expertise. You are opening a factory or an R&D site and you want to demonstrate your command of it. The opening includes a demonstration tour. Audience: industrial clients, specialist press, technology partners. Format: guided tour + demonstrations + reception.

Objective 4: celebrating an anniversary. You are (officially) opening a site that already existed, on the occasion of a company anniversary. The event is more festive and less formal. Audience: loyal clients, staff, long-term partners. Format: celebration + retrospective + festive evening.

Be clear about the objective from the brief stage. A multi-objective opening is generally disappointing on every front.

2. The production schedule: 4 to 6 months

An opening takes 4 to 6 months to prepare for classic formats, 8 to 12 months for openings with a government minister or a leading public figure.

J-180 to J-150: strategic brief, choice of date (take into account the political calendar, school holidays, major competing events), first guest list, budget approval.

J-120: choice of event provider, choice of structure and staging, approval of the protocol programme.

J-90: sending out paper or digital invitations (depending on your level of expectation). Confirmation of the speeches (who speaks, in what order, for how long).

J-60: early follow-up with non-respondents, finalising logistics (transport, accommodation, catering), approval of the ERP safety file.

J-30: final confirmation of attendance, last adjustments to the programme, press briefing, seating plan if there is a dinner.

J-15: final site visit, rehearsal of the speeches, final approval of the technical set-up.

J-3: start of the setup of the structures and the staging.

J: opening. Full technical standby, event team on site from 6 am.

J+1 to J+5: post-production (media kit, high-definition photos, summary video, final press release), takedown, review.

3. Protocol and speeches

The protocol of an opening is a sensitive subject, particularly when elected officials or institutional figures are present.

Order of speeches: from the least important to the most important. Typically: project manager / architect (5 min), company director (10-15 min), local elected official or Chamber of Commerce president (5-10 min), national elected official if present (10-15 min). In total, do not exceed 45 minutes of combined speeches.

The opening ribbon: a strong protocol symbol. To be cut by the most important figures (usually the mayor + the director). An official photographer must capture the moment. A bespoke ribbon in the company's colours + a local element.

The opening plaque: to be unveiled by the figures during a staged moment. Engraved or printed, it remains on the site as a lasting record. Protocol wording approved in advance with the elected officials present.

The seating plan for a seated dinner: strict protocol. The most important figure to the right of the company director, the second figure to their left, alternating men / women after that, mixing internal / external guests.

Protocol gifts: to be presented to the figures at the end of the ceremony. A quality object, French-made, linked to the company (a book on the company's history, a local artisan object, a bespoke sculpture). Budget: 150-500 € per protocol gift.

4. Managing elected officials and institutional guests

Inviting and welcoming elected officials is a specific skill.

Protocol invitations: sent 4-6 months in advance, signed by the company director (and not an assistant), in paper format (and not digital). A precise postal address, official wording (Mr Mayor, Mr Prefect).

Office follow-up: for important elected officials (mayor of a large city, prefect, government minister), a follow-up with their office to confirm the diary, approve the protocol, clarify expectations. This requires 2-3 telephone exchanges.

On-site welcome: a team dedicated to welcoming the elected officials, a separate cloakroom, a premium waiting area, coffee / drinks, a quick briefing on how the ceremony will unfold.

Security plan: for government ministers, the SDLP (the high-profile protection service) imposes a specific security set-up (entry airlock, checks, perimeter). To anticipate at least 60 days in advance with the prefecture.

Official photographer: compulsory institutional photos (handshake with an elected official, plaque unveiling, signing of the guest book, ribbon). To be sent to the offices the following day for their communication.

Co-signed press release: for major openings, the release is co-signed with the local authority or the institution. Advance approval of the text, official photo jointly provided.

5. The press set-up

The press is a central player in openings. Here is how to integrate it properly.

Press kit: handed to each journalist on arrival. Contents: press release (1 page), full press pack (5-8 pages), high-definition photos (logo, director, site, products), institutional video, press contacts (communications director, press officer, director).

Targeted press invitations: not a mass mailing. Hand-picked journalists, with a personal note where relevant. For a local opening: regional press + national business press + sector press. For a major opening: add specialist international press.

Dedicated press area: an entry airlock separate from the public, a clean cloakroom, a media kit handed over, a partitioned interview area with controlled lighting, premium Wi-Fi, power for cameras. Today, this is the standard expectation of any serious journalist.

Official photo: a professional photographer who delivers the photos within J+1 at the latest (ideally overnight for the next day's print editions). Royalty-free high-definition photos for the invited journalists.

Live tweet and social media: a community management team on site, live photos, quotes from directors, backstage atmosphere. Social coverage extends the press coverage by 2-3 days.

Post-event press monitoring: a full press review at J+7, shared with the VIP guests, archived. Measuring the impact in EAV (advertising-equivalent space).

6. The staging and scenography

The opening is one of the most demanding events in terms of scenography. Here are the key elements.

The structure: for an opening on an industrial site or outdoors, a premium marquee or a transparent orangery are almost compulsory. The structure becomes the décor and shelters all the guests whatever the weather conditions. For an indoor opening, the structure is less critical but the scenography remains essential.

The signage: large-format welcome boards, protocol flags if there are elected officials, branded signage in the company's colours + a local element. Signage budget: 2 000-8 000 € depending on scale.

The ribbon and the plaque: central protocol elements, to be designed with care. A bespoke woven ribbon (200-500 €), a plaque engraved on fine metal (500-2 500 €).

Stage lighting: architectural lighting to enhance the site (illuminated façades, lit ground), stage lighting for the speeches, festive lighting for the reception. Budget: 4 000-15 000 €.

The Step & Repeat photobooth: a wall with sponsor / partner / institution logos, in front of which guests are photographed on arrival. Budget: 1 500-4 000 €.

4K video capture: essential for high-stakes openings. A 3-5 minute summary video edited and delivered within J+5 at the latest. Budget: 4 000-12 000 €.

Furniture and table settings: for an opening with lunch or dinner, careful table settings (premium tablecloths, quality tableware, floral decoration, named place cards). Furniture + table setting budget: 4 000-15 000 €.

FAQ

Vos questions, nos réponses

No, it is neither compulsory nor always relevant. Advantages of having a government minister / leading elected official: wider press coverage, institutional endorsement, prestige for the guests. Disadvantages: heavy protocol, demanding security set-up, strong diary constraints (cancellations possible at J-2), less personal speeches. For local openings (a shop, an SME site), stick to local elected officials (the mayor, a county councillor): relevant, accessible, valued. For major openings (head office, factory, national R&D), you can move up the protocol scale.

Short format (3h): welcome 30 min + ceremony 45 min + reception 1h45. Ideal for local openings and for guests with busy schedules. Standard format (4h): welcome 30 min + site tour 45 min + ceremony 30 min + standing dinner reception 2h. This is the most common format for B2B openings. Premium format (5-6h): welcome 45 min + tour 1h + ceremony 45 min + reception 1h30 + seated dinner 2h. For high-stakes openings and premium audiences. Avoid exceeding 6h: beyond that, the energy drops.

Three options. Option 1: a strictly professional invitation (no partners). The most common format in France. It simplifies management and does not double the capacity. Option 2: inviting partners for the most important guests (elected officials, partner directors). A frequent protocol practice. Marginal cost. Option 3: inviting partners across the board. The practice for very festive openings or family-style company cultures. It doubles the capacity, but creates a warmer event. If you invite partners, be clear from the invitation onwards and adapt the format (a standing dinner reception rather than a formal seated dinner).

Five rules. First rule: keep it short (8-12 minutes maximum). Your guests are standing, their attention is limited. Second rule: a clear structure (where we come from, where we are, where we are going, who to thank). Third rule: a personal message (a real-life anecdote, a personal vision, a conviction). Fourth rule: targeted thanks (not a list of 30 names: 5-7 important names, the rest go on the card handed to the guests). Fifth rule: finish on an image (a vision of the future, a strong quote, a concrete action). Prepare this speech 2 weeks in advance, and rehearse it aloud 2-3 times before the day itself.

Yes, it is almost always relevant for the opening of an industrial site, a head office or an R&D facility. Format: guided tours in sub-groups of 8-12 people, lasting 30-45 minutes, 2-3 guides briefed in advance, focusing on the structuring elements (an emblematic workstation, a signature piece of equipment, a product demonstration). For particularly sensitive sites (confidential R&D, production under industrial secrecy), plan a partial tour with « no-photo » zones and a confidentiality briefing. The tour considerably strengthens the quality of the opening and gives the guests something to talk about the next day.

Favour spring (April-May-June) or the start of the autumn season (September-October). Avoid: July-August (holidays, scattered audiences), November to mid-December (competing with end-of-year parties), January (a busy start to the year, audiences less available). If you have a strong calendar constraint (completion of works, an internal requirement), prioritise as a second choice the Thursdays and Fridays in the middle of the month (this avoids weekend departures and the start-of-month rush). Openings on a Tuesday or Wednesday also perform well for corporate audiences.

Three options. Option 1: an external opening (clients / partners / elected officials / press) then a separate internal party the same evening or the next day. This allows both audiences to be managed well, each with their own conventions. Option 2: a mixed opening (external guests + staff at the same time). This creates a strong sense of unity but requires careful management of the protocols. Option 3: a symbolic presence of staff (the opening of the director's speech in the presence of a staff delegation) then a separate internal party. Most large openings choose option 1 or 3. A dedicated internal party values your teams without diluting the external message.

Five indicators. Media coverage: number of articles, cumulative audience, EAV (advertising-equivalent space). Social media engagement: reach, mentions, hashtags. Sales pipeline: leads generated over the following 90 days among the guests present, deals advanced or signed. Partner / client sentiment: a satisfaction survey at J+30, NPS attributed to the event. HR impact: the sentiment of the staff present, spontaneous applications within 90 days, employer-brand perception. A good measurement mixes short-term indicators (media, engagement) and long-term ones (pipeline, brand equity). Document these KPIs from the brief stage so that you can measure them afterwards.
