Bring your membership CRM, renewals, payments, events, CPD, learning, communications, community, job board and reporting together in one place. Every plan includes the staff licences your team needs to get started, with simple pricing for additional users as you grow.
30-day free trial, no credit card required. 90-Day Fit Guarantee: if we miss the agreed workflows, you leave with your data.
One plan replaces the separate membership database, event booking site, email tool, LMS and website CMS most organisations pay for today. Start with an included allowance of full staff licences, then add more only when your team needs them. Members, applicants, learners, event attendees and other portal users are not charged as staff seats.
For smaller associations and professional bodies moving away from spreadsheets or an outdated database.
For established organisations ready to manage membership, events, learning and engagement from one platform.
For larger professional bodies with complex qualifications, workflows, integrations or reporting needs.
For national, international or multi-entity organisations requiring tailored architecture and support.
Prices exclude VAT. Card payments taken through Colossus are processed by Stripe, whose processing fees are charged separately at its published rates. SMS usage, bespoke development, complex data cleansing and specialist external licences are also charged separately where required.

Not the right fit for everyone: a small club that only needs a contact list and a sign-up form will be better served by a free tool. Colossus is for associations, professional bodies and charities with a membership team and renewals, events or CPD to run.
Qualifying new Growth customers receive more licences during adoption, practical migration support and clear protection around implementation and fit.
Promotional licences become chargeable after 12 months unless removed before the promotional period ends. Standard migration scope and eligibility are confirmed during discovery.
Full licences are for day-to-day management. Contributor and read-only access keep occasional users connected without unnecessarily increasing your cost.
For administrators managing members, payments, renewals, communications, events, learning, reports or platform settings. Included quantities vary by plan.
From £29 per month for restricted access to assigned areas. Ideal for event coordinators, content editors, assessors, committees and regional teams.
Member portal accounts are included. Complimentary read-only access is available for trustees, directors and stakeholders who need visibility without editing rights.
Your implementation is shaped around agreed workflows, responsibilities, data quality and launch priorities.
We document your critical workflows, integrations, data sources and success measures before configuration begins.
Your plans, fields, forms, processes and permissions are configured before test data is imported and reviewed.
Your team completes guided training and acceptance testing, with issues resolved before the final migration.
We support go-live, monitor early use and help your organisation develop additional journeys and capabilities.
Book a tailored demonstration around your membership model, workflows and current systems. We will show the most relevant modules and provide a clear recommended plan.
No generic sales presentation. Your demonstration is shaped around the processes your team actually needs to manage. Prefer to try it first? The 30-day trial needs no card details.
