To plan a corporate event without surprises you need to cover five fronts in order: definition (goal, audience, budget), contracting (venue, AV, catering), invitations (outreach and accreditation), event-day operations (team, run of show, contingencies) and closing (payments, measurement, report). This checklist walks through all five, counting back in weeks from the event date, so you know what to tick off at each point and what cannot wait.
It is built for a typical corporate event of a few hundred people: a convention, a launch, a company day, a year-end dinner. If your event is smaller, you will tick things off fast; if it is bigger, each item gets deeper, not different.
12 weeks out: definition
Everything that follows depends on this stage. Skip it and the rest of the checklist becomes firefighting.
- Event goal defined in one sentence. Sell, train, build loyalty, celebrate, position the brand. If it does not fit in one sentence, it is not defined.
- Target audience and estimated headcount. Who is coming, how many, what they expect. The format comes from here.
- Tentative date checked. Against public holidays, industry events, the calendar of key guests and seasonal weather if there is an outdoor component.
- Indicative budget approved. With a contingency line of 8% to 12% included from day one. If you have never built one, this guide on how to build a realistic event budget gives you the structure.
- Production decision: in-house or with a production company. If you are going to get quotes from production companies, now is the time, not at 6 weeks.
8 weeks out: contracting
The rule at this stage: what is scarce gets booked first. Good venues, AV and catering sell out on good dates.
- Venue booked and contract signed. With licensed capacity verified, a clear catering policy and build-up times agreed in writing.
- Technical production quoted and closed. Sound, screens, lighting and streaming if there is any. Ask for the quote to include build-up, operation and teardown.
- Catering defined by format. Coffee break, lunch, cocktail or dinner, with a menu for dietary restrictions (vegetarian, gluten-free) from the start, not as a last-minute exception.
- Speakers and content confirmed. With their technical needs surveyed: presentations, interpreting, green rooms.
- Insurance and permits in progress. The ones the event needs and the ones the venue requires. Paperwork does not speed up with money: it speeds up with lead time.
Real lead times for each item vary by type of event; in how long it takes to produce an event you will find reference timelines by format.
4 weeks out: invitations and accreditation
This is where the event stops being an internal plan and starts to exist for guests.
- Invitations sent with online registration. With a form that captures what operations needs: contact details, dietary restrictions, accessibility needs.
- Accreditation system defined. QR, physical badge or both; guest categories (general, VIP, press, staff) and what each one can access. If you are torn between technologies (QR, RFID wristband or facial recognition), decide based on the event format and the expected entry flow, not on novelty. Our accreditation guide for conferences and trade shows goes deeper.
- First read of confirmations. If, at 3 weeks out, fewer than 40% of the expected guests have confirmed, it is time to push outreach, not to wait for a miracle.
- Suppliers with a purchase order or deposit. A supplier without a committed payment is a supplier who can take another job.
- Communication pieces in production. Signage, badges, screens, printed materials. Everything that gets printed has a real deadline.
1 week out: operations
The week before is not for deciding: it is for checking. Anything decided now gets paid for in stress or in money.
- Run of show closed and distributed. The minute-by-minute plan of the event, with an owner per item, shared with AV, catering, venue and staff.
- General coordination meeting held. Every area lead at the same table (or on the same call), going through the run of show end to end.
- Staff confirmed and briefed. Reception, accreditation, room coordinators, hosts. Each person knows their post, their schedule and who they report to.
- Technical rehearsal scheduled. With real content: the actual event presentations, not a test slide.
- Written contingency plan. What happens if it rains, if the power goes out, if the internet drops, if a speaker does not show up. With the name of who decides in each case.
- Final guest list loaded. With a defined cut-off: until when new registrations are accepted and who authorizes exceptions at the door.
On the day
| Moment | What to check | Typical owner |
|---|---|---|
| 4 to 6 hours before | Build-up finished, cleaning done, signage in place | Floor manager |
| 2 to 3 hours before | Full technical rehearsal with real content | Technical producer |
| 1 hour before | Accreditation running, with a backup if the internet drops | Head of access |
| Doors open | Staff at their posts, radios working, catering ready | Executive producer |
| During | Run of show to the minute, adjustments by radio, VIP care | Everyone, on channel |
| Close | Orderly egress, cloakroom, transfers | Floor manager |
One detail separates tidy events from chaotic ones: a single decision channel. When something unexpected happens, everyone knows who to escalate to, and that person can decide. Two bosses at the same event are the same as none.
After the event: the closing almost nobody does
The event does not end when the last guest leaves. A professional close has four steps:
- Teardown and returns. Equipment, furniture, staff credentials, venue keys. With a condition report if the contract requires it.
- Financial reconciliation. Invoices against budget, documented extras, contingency used or released. Undocumented extras are next month’s arguments.
- Measurement against the goal. Actual attendance against confirmations, a satisfaction survey and the indicators you defined in week one. We cover exactly what to measure in how to measure event success.
- Post-event report. Two honest pages: what worked, what did not, what to change next time. It is the cheapest document to produce and the one that saves the most money on the next edition.
An honest warning about checklists
This checklist covers order and memory, which are half the job. The other half is judgment: knowing when a “beautiful” venue will not work, how much AV is enough, which supplier delivers and which one just promises. That half cannot be ticked off: you either hire it or learn it the hard way.
If you would rather hire it, SOMOS DER produces corporate events end to end: definition, suppliers, accreditation, food service and event-day operations, with one party accountable for making all of this happen. Ask us for a quote and we will build your event plan on this same structure.
