What it is
Congressio brings conference submissions, peer review, decisions, scheduling, and attendee registration into one platform. Its drag-and-drop form builder supports conditional logic, uploads, and co-author invitations, while review tools include automatic reviewer assignment, deadlines, conflict-of-interest detection, and double-blind review. Organizers can publish a public program with attendee agendas and iCal or PDF exports. Ticket sales through Stripe support tiers, discounts, add-ons, VAT invoices, and refunds. QR passes can be stored in Apple and Google Wallet and scanned at check-in, with zones controlled by ticket tier or capacity. Virtual-event tools include live and on-demand streaming, recordings, e-posters, Q&A, and polls. Congressio also describes ORCID, institutional single sign-on, API keys, and webhooks for integrations. It says data is kept in the European Union and card details are handled by Stripe. The free plan allows one active event, 100 submissions, and three team seats. Standard costs $49 a month; a 14-day trial is listed.

Congressio in depth
Read the full write-up
Overview
Congressio is a conference-management platform that spans submissions, peer review, programming, ticketing and attendee access. It is best suited to organizers who want academic review and event operations in one system, including teams running virtual sessions. Its breadth is a strength, but the free tier is sized for small events and ticket payments cover only three currencies.
Key features
The drag-and-drop form builder supports conditional logic, file uploads and co-author invitations without code. Multiple submission types, author revisions and poster handling accommodate varied calls for papers. That flexibility is useful when organizers need different fields or processes for different submissions.
Review tools include custom workflows, scoring, automatic reviewer assignment, deadlines, conflict-of-interest detection and double-blind review. These cover the route from submission to decision; advanced review analytics require Professional, so teams that depend on analytics should account for the higher plan price.
Organizers can publish a public program with attendee agendas and iCal and PDF exports. Ticketing supports tiered sales through Stripe, discount codes, add-ons, VAT invoices and refunds. QR passes work with Apple and Google Wallet and can be scanned at check-in; access zones can be gated by ticket tier or capacity. Together, these features connect registration to event entry, but online ticket payments accept only EUR, GBP and USD.
For virtual events, Congressio supports live and on-demand streaming, recordings, an e-poster gallery, Q&A and polls. Integrations include Stripe, Apple and Google Wallet passes, ORCID, institutional single sign-on, API keys and webhooks. Congressio says data is kept in the European Union and card details are handled by Stripe rather than stored in its systems. It says support typically replies within one business day and prioritizes urgent requests during an active event.
Pricing
Congressio is freemium, with paid plans from $49 a month and a 14-day trial. The free plan costs nothing and includes one active event, 100 submissions and three team seats, with forms, review, decisions, program and email. That is a useful starting point for a small event, but the event, submission and seat limits leave little room for growth.
Standard costs $49 a month and raises capacity to five active events, 1,000 submissions and 15 team seats. It adds custom event branding, email campaigns and reminders, making it the practical step up for organizers managing several events or larger submission rounds.
Professional costs $149 a month and includes unlimited active events, submissions and team seats, plus advanced review analytics, custom event branding and priority support. It fits larger or repeat-event teams that need scale and deeper review reporting; the jump from Standard is substantial, so smaller organizers may not benefit from its uncapped quotas.
Enterprise has custom pricing and includes everything in Professional, plus SSO / SAML, custom limits, custom contracts and invoicing, and dedicated support. It is intended for organizations that need those controls or tailored terms rather than another fixed-cap plan.
Platforms
Congressio runs on the web and provides an API. Its interface is available in English, German, Spanish, French, Italian and Portuguese. The maker describes it as designed for both academic and non-academic conferences.
Who it's for
Congressio is a good fit for conference teams that need submissions, configurable review, scheduling and attendee registration together, especially when ticketing, access control or virtual sessions are part of the event. It is less suitable for organizers who need to charge attendees in currencies beyond EUR, GBP or USD, or whose event exceeds the free plan’s caps without budget for a paid tier.
Pros and cons
Pros: A broad workflow connects submission forms, peer review, published programs, ticket sales and check-in, reducing the need to separate those conference tasks.
Pros: Review options include conflict checks, double-blind review, custom workflows and scoring, which suit conferences with structured evaluation needs.
Pros: The free plan includes core forms, review, decisions and program features, giving small events a way to begin without a subscription.
Cons: Free capacity is limited to one active event, 100 submissions and three seats, so a growing event team will need to upgrade.
Cons: Online ticket payments are restricted to EUR, GBP and USD, excluding organizers who need to charge in other currencies.
Cons: Advanced review analytics and unlimited quotas start at $149 a month, which may be more than smaller teams need.
Alternatives
Browse the Event Abstract Management Software directory for more options. Choose Eventact if Android and iOS apps matter; its listed registration and website plan for under 2,000 attendees per year costs $210 a month. Fourwaves offers a free Starter plan with 25 abstract submissions per year, unlimited registrations and events, and a 3% service fee, making it an option when that submission allowance suits the event. AbstractWiz is another freemium choice: its free plan allows up to 20 submissions, while a one-time 270.00 USD Standard plan includes unlimited submissions and all features.
Indico is free, open-source and self-hosted, for teams that prefer that deployment model. ConfTool offers a free license on request for smaller non-commercial events of up to 150 participants, with local installation and no support. HotCRP has free plans for ACM- or USENIX-sponsored conferences, journals and workshops. SimplyConf has a free Core plan with unlimited events, submissions and users. OpenConf offers a Community Edition for three or fewer events and journals per calendar year.
Verdict
Choose Congressio if your conference team wants one platform for review, programming, registration and event access, with virtual-event tools as well. Its free plan makes the core workflow accessible to a small event, while Standard provides a defined growth step. Look elsewhere if your ticket sales require currencies beyond EUR, GBP and USD, or if you need substantial capacity and advanced analytics without moving to Professional.
Verdict
Congressio covers conference planning from submissions and review through ticketing and attendee access. Check its free-plan caps and supported payment currencies against the size and needs of your event.
