An enterprise event management platform built in 3.5 months for £15,000

A traditional software agency would quote £995,000 and take three to four years with a team of five to seven developers. This platform was built by one person in 3.5 months for £15,000 in direct costs. That is not a typo.

The situation

The client runs roadshow events connecting NHS Trusts with healthcare technology suppliers. Medical suppliers showcase their products directly to nurses, GPs, and clinicians inside hospitals and trusts across the UK. Coordinating these events means managing a web of moving parts. Exhibitor applications and approvals. Host trust relationships and logistics. Sales partner commissions. Contracts and e-signatures. Email campaigns. Registration forms. Post-event reporting. And a database of NHS organisations that needs to stay current.

Before this platform existed, those processes ran through a patchwork of separate tools. A CRM here. A spreadsheet there. Email chains everywhere. Every event required manual coordination across multiple systems that didn't talk to each other. The team spent more time managing tools than managing events.

Commercial alternatives exist, but they're built for conferences, not healthcare roadshows. Platforms like Cvent or Bizzabo cost £75,000 to £750,000 a year in licensing. They don't understand NHS trust structures. They don't handle UK-specific requirements like VAT or BACS payments. And they certainly don't integrate with NHS data systems.

What we built

A complete event management platform with five separate portals, each designed for a different type of user.

The admin portal gives the internal team full control. Create events, manage exhibitor applications, track bookings, generate contracts, send email campaigns, run reports, and monitor the entire pipeline from a single dashboard. Two department-specific views give the accounts team and events team their own focused workspace with the KPIs that matter to them.

The exhibitor portal lets suppliers manage their own profiles, view upcoming events, submit applications, upload documents, and complete post-booking forms including logo uploads. No more chasing suppliers for information by email.

The host portal gives NHS trusts a clean view of events planned at their sites. A public version of this dashboard works without any login at all, reducing inbound admin queries from trusts who just want to check what's coming up.

The sales lead portal tracks commission partners through a full prospect pipeline. Referral codes, commission rates, conversion tracking, and performance analytics. Partners access it through a magic link with no password required.

The platform pulls live data from the NHS ODS API using the FHIR R4 standard. Over 45,000 NHS organisation and site records sync automatically, with a management interface that shows diff previews before committing changes and supports one-click rollback to any previous import. That integration alone is unique in this market.

Contracts go out through DocuSign or BoldSign with automated counter-signatures. HubSpot syncs bidirectionally so the CRM stays current without anyone copying data between systems. Email campaigns build visually through a drag-and-drop editor and send through AWS SES. Events display on interactive maps with colour-coded status markers. Everything exports to PDF, Excel, or CSV.

The platform includes role-based permissions, audit logging, feature flags, GDPR compliance tools, accessibility testing, and a guided onboarding tour for new users. A WordPress plugin with three Elementor widgets embeds event listings, registration forms, and calendar views directly into the client's existing website.

The numbers

Traditional agency Tyree Digital
Cost£995,000£15,000
Timeline3.5 to 4.5 years3.5 months
Team required5 to 7 developers1 person
Saving£980,000 (98.5%)

The platform reached 130,396 lines of production code across 921 commits. 79 major features. 93 database migrations. 29 test files covering backend logic, frontend components, and NHS API sync. 60 documentation files.

If operated as a SaaS product at £200 to £500 per month per organisation, 40 customers would generate £240,000 in annual revenue. The entire build cost pays for itself within the first month of operation at that scale.

The cost comparison against commercial licensing is equally stark. Replacing this platform's functionality with a combination of Cvent, HubSpot Sales Hub, and DocuSign would cost £175,000 to £370,000 a year. Every year.

What the client owns

A fully self-contained software asset with no vendor dependencies. The code, the infrastructure, the NHS data integrations, the CRM connections, the contract workflows, and every byte of customer data. All of it sits in the client's own AWS account.

The live NHS ODS FHIR R4 integration is a genuine technical moat. No other event management platform in this market connects directly to NHS organisational data. Combined with the five-portal architecture and the HubSpot bidirectional sync, the switching costs for any organisation using this platform increase with every event they run.

What happens next

A monthly subscription covers hosting, maintenance, and ongoing development. The remaining steps to full commercial launch are final production deployment, load testing, user acceptance testing, and a security audit.

The roadmap beyond launch includes payment processing with Stripe, mobile apps, advanced AI features, and white-label capability for licensing to other event management companies. Each of those additions builds on the existing architecture without requiring infrastructure changes.
