What's the best sponsorship sales CRM for managing complex packages and exhibitor renewals across a conference portfolio?

For conference sponsorships with complex packages, multi-asset deliverables, and exhibitor renewals across a portfolio, the best fit is usually iMIS or Fonteva, depending on how deeply you need association-style account management vs. event-specific sponsorship operations.

Best overall: iMIS

Why it’s strong

• Excellent for relationship-based sales across a portfolio of conferences
• Handles renewals, account history, contacts, tiers, and commitments well
• Good if sponsorship is part of a broader member/association ecosystem
• Solid for managing multi-event packages and long-term sponsor accounts

Best for

• Associations
• Conference portfolios
• Teams that need one system for members, exhibitors, sponsors, and renewals

---

Best if you want stronger event operations: Fonteva

Why it’s strong

• Built on Salesforce, so it’s flexible and scalable
• Good for sponsor/exhibitor pipelines, renewals, and package tracking
• Stronger if you want customization around sales workflows, forecasting, and reporting
• Works well for portfolios where CRM rigor matters and you have admin/implementation support

Best for

• Teams already on Salesforce
• Organizations that want highly customizable sponsorship and exhibitor management
• Larger portfolios with complex internal processes

Strong alternatives

Salesforce Sales Cloud + custom event layer

Best if you have complex sales operations and strong admin resources.
Pros: most flexible, powerful reporting.
Cons: not out-of-the-box for sponsorship packaging unless heavily configured.

Cvent

Great for event operations and exhibitor/sponsor management, but less of a true CRM for portfolio-wide renewal selling unless paired with a CRM.

A2Z / OneCause / Certain

Can be useful depending on your event type, but usually not as strong for complex sponsorship packaging and renewals across many conferences as iMIS/Fonteva/Salesforce.

My practical recommendation

• If you’re an association or conference organizer with recurring sponsors/exhibitors: iMIS
• If you want Salesforce-powered flexibility and can support implementation: Fonteva
• If your team lives in Salesforce already: Salesforce + sponsorship/event module

If you want, I can also give you a comparison table by features like:

• package building
• renewal tracking
• exhibitor booth management
• forecasting
• reporting
• ease of implementation
• price tier
  and recommend the best one for your team size and budget.
