A successful conference starts with a timeline, not a venue booking. An international event for 200–500 delegates usually needs 12–18 months of preparation; a local seminar or forum, 3–6 months. Below is the timeline we use when planning conferences in Lithuania, with concrete tasks for every stage.
12 months out: purpose, budget, dates
- Purpose and audience. Who will attend, how many people, which language, and whether the event is scientific, professional or public.
- Initial budget. Costs and income sources: registration fees, sponsors, grants or public funding. In Lithuania, remember to budget for VAT (21%) and payment provider fees.
- Dates. Check for other major events in the city at the same time and avoid public holidays and peak vacation weeks.
- Committees. A local organizing committee handles logistics and finances; a programme (scientific) committee owns the content.
The most common mistake at this stage is leaving no contingency. We recommend keeping around 10% of the budget in reserve.
9–12 months: venue and accommodation
- Venue selection. Plenary hall capacity, breakout rooms, space for coffee breaks and exhibitors, technical equipment, public transport access. Vilnius is compact: many venues, hotels and the Old Town are within walking distance of each other.
- Hotel room blocks. Negotiate room allocations for delegates with clear release dates.
- Contracts. Read the minimum guaranteed attendance, payment schedule and cancellation terms carefully.
6–9 months: website, registration, call for papers
- Event website with the programme, fees, deadlines and practical information.
- Registration system with online payment and automatic invoices – see our event registration systems.
- Abstract submission and review, if it is a scientific conference.
- First announcement and sponsorship packages with clear benefits for each level.
- Privacy policy and GDPR-compliant handling of delegate data.
3–6 months: programme, speakers, sponsors
- Final programme and speaker confirmations, including their travel and accommodation.
- Social programme: welcome reception, conference dinner, city tours or excursions.
- Catering menus and dietary requirements collected through registration.
- Technical specification: sound, video, simultaneous interpretation, streaming.
- Volunteer team recruitment – see event logistics and volunteers.
1–3 months: logistics and communication
- Early-bird deadline and reminders to delegates.
- Delegate guide: how to get there, where to register, Wi-Fi, emergency contacts.
- Name badges, signage and printed materials.
- Airport transfers if many delegates travel from abroad.
- Volunteer briefing and a shift schedule.
The final week and event days
- A minute-by-minute run sheet for the whole team and all suppliers.
- A technical rehearsal in the hall with the speakers’ slides.
- A registration desk that opens at least one hour before the start.
- One person responsible for each area and a single shared communication channel.
After the event
- Thank-you messages to delegates, speakers and sponsors within a week.
- A delegate survey while impressions are fresh.
- Certificates of attendance, presentations or proceedings.
- Financial and activity reports – especially for grant-funded events.
Five common mistakes
- Booking the venue too late. Popular conference venues and hotels are often booked more than a year ahead for spring and autumn dates.
- Registration without payment. When delegates register first and pay separately, payments arrive late and accounting becomes manual work.
- Unclear deadlines for speakers. Late abstracts and slides delay the programme and the proceedings.
- One person responsible for everything. On the day, nobody can handle registration, AV and catering at the same time.
- No plan B. A speaker cancels, the power or internet fails, it rains during an outdoor event – back-up solutions should be agreed in advance.
Frequently asked questions
How long does it take to organize a conference?
A local one-day event for up to 150 people usually needs 3–6 months. For an international multi-day conference with invited speakers, start 12–18 months ahead; large congresses often reserve their venue even earlier.
Why host a conference in Lithuania?
Lithuania is in the EU and the euro area, Vilnius is compact and walkable, and venue and hotel costs are typically lower than in many Western European capitals. A local organizer helps you with suppliers, language and practical details.
Can the conference be hybrid?
Yes, but a hybrid format needs its own budget and team: streaming equipment, a moderator for online participants and a platform for questions. Choose it when remote attendees are a real audience, not just “in case”.
When to bring in a professional conference organizer (PCO)
If you expect more than 150 delegates, many of them travel from abroad, or the organizers run the event alongside their day jobs, a professional conference organizer (PCO) takes over logistics, registration, financial administration and supplier coordination – so the committee can focus on the programme.
