Pricing models are indicative; each vendor’s packaging and rates change. Request current proposals based on your volumes.

Five9

Five9 offers a broad, packaged suite: inbound and outbound voice, digital channels, intelligent routing, workforce engagement and AI features. It suits organizations that want a complete platform with less custom development and strong outbound dialing, such as sales and collections teams.

Amazon Connect

Amazon Connect is AWS’s cloud contact center service, priced on usage, so costs scale with activity rather than seat counts. It integrates with AWS services for analytics, transcription and AI, and with Salesforce through Service Cloud Voice or integrations. It suits organizations comfortable with AWS and variable volumes.

Twilio Flex

Twilio Flex is a programmable contact center: the agent interface, routing and channels can be customized extensively with code, built on Twilio’s communications APIs. It suits companies with developer capacity that want a highly tailored experience.

How to shortlist

  1. Map your channels: voice, SMS, chat, email, social messaging.
  2. Estimate volumes and patterns, including peaks and seasonal swings.
  3. Decide how much customization you need versus out-of-the-box features.
  4. Assess your in-house skills: administrators, AWS engineers or developers.
  5. Check outbound needs, compliance requirements and reporting.
  6. Confirm the depth of integration with your CRM.

CRM integration is critical

Agents should see the customer’s record when a call arrives, and every interaction should be logged in the CRM. Evaluate screen pops, click-to-dial, call logging, recordings, transcripts and how routing can use CRM data, such as sending VIP customers to senior agents.

We integrate contact center platforms with Salesforce; see our system integration services.

A shortlisting example

A healthcare provider with steady inbound volumes, strong outbound appointment reminders and a small IT team might favor a packaged platform such as Five9. A retailer with large seasonal peaks and an AWS-savvy team might prefer Amazon Connect’s usage-based model. A technology company wanting to embed contact center features in its own product could choose Twilio Flex for its programmability.

Questions for vendor demos

  1. Show a call arriving with the customer’s Salesforce record on screen.
  2. Show how a supervisor changes routing during a spike.
  3. Show how call outcomes appear in Salesforce reports.
  4. Explain total cost for our volumes, including telephony and AI features.

Frequently asked questions

Which is cheapest?

It depends on volumes and usage patterns. Usage-based pricing suits variable volumes; per-agent pricing can be predictable for steady teams.

Do all three work with Salesforce?

Yes, through adapters, Service Cloud Voice or custom integrations, with differing depth and effort.

Do we need developers for Twilio Flex?

Flex is designed for customization, so developer capacity, in-house or through a partner, is important.
