How to choose congress software: a buyer’s checklist

Congress software is easy to choose badly. Every tool demos well, every vendor is confident, and the gaps only show up in the busy weeks before the event — or at the registration desk on the morning. The way to avoid that is to evaluate against your own requirements and your own data, not against a polished sales call. Here is a checklist that does exactly that.

1. Write your non-negotiables first

Before you see a single demo, list what your congress genuinely cannot do without. For a scientific congress that usually includes:

• native abstract submission and peer review;
• a structured program built from accepted abstracts;
• offline check-in and badge printing;
• sponsor lead retrieval;
• group and invoice registration for institutions.

Score every tool against this list. A feature demoed beautifully but not on your list is not a reason to buy.

2. Test with your real data

This is the step that separates the tools that work from the ones that only demo. Import a past program and a batch of your actual abstracts. Watch what breaks — odd characters, multiple affiliations, parallel sessions, your specific formatting. The tool that stumbles on your content now will stumble on the day.

3. Check the attendee experience on a phone

Most of the congress happens on attendees’ phones, so judge the app as an attendee would: personal agenda, notifications, networking, offline access. A clunky attendee app undoes a great back office.

4. Prefer one dataset over stitched-together tools

A scientific congress lives or dies on data flowing between abstracts, program, check-in, and the app. An integrated platform shares one dataset; a stack of separate tools makes you move data by hand between them. We compare the two approaches in Lumina vs a generic event platform.

5. Compare total cost, not sticker price

1. Add up every tool and add-on you would actually need, not just the base license.
2. Watch pricing that scales per attendee — it punishes a successful congress.
3. Count staff time spent moving data between tools; it is a real cost.

A single flat price per congress is the easiest to budget and defend — the model behind Lumina’s pricing.

6. Confirm support during the event

Ask who you reach at 8:45 on day one if check-in fails — and how fast. Support during the sales call tells you nothing; support during the event is what you are actually buying.

The buyer’s checklist

1. Does it cover every non-negotiable natively?
2. Did it survive a test with your real program and abstracts?
3. Is the attendee app genuinely good on a phone?
4. Does data flow between modules without manual transfer?
5. Is the total cost predictable as the congress grows?
6. Is there real support during the event?
