Featured Reviews

Abeer ELADAWY - PeerSpot reviewer
Provides omnichannel AI features and has good routing capabilities
The routing capabilities are excellent. We have priority routing set up for VIP customers, disabled customers, and those with special needs, ensuring they receive prompt and efficient service. We have implemented a use case where AI helps when a customer calls and says, "My bill is high." The AI searches the customer's profile to check if the high consumption is real or just a misunderstanding. If it is high, the AI creates a notification for the backend to check the issue. The system automatically generates the bill and the notification for the agent, who then views and either submits or rejects the notification. I recommend using the solution for all the features I have mentioned before, including the excellent AI experience, omnichannel, self-service, and customer journey features. I rate it a nine.
Devan Baucom - PeerSpot reviewer
Has many features, provides good technical support, is scalable, and has no downtime
Five9 has a lot of AI tools, which I find valuable. It offers transcription services and a power dialer for outbound dialing. I like that Five9 is built for outbound and suitable for that purpose. Another valuable feature of the solution is the screen pop where, as a rep or agent, when your customer answers the phone, you'll immediately see customer details on your screen, which is helpful, especially if you have a lot of customers. Five9 also has the Intelligent Virtual Agent feature, which I find good, though there may be some legal implications. Still, I find Five9 a great solution that seamlessly helps customers engage with brands. Agent Assist is another good feature of Five9. That feature is useful because you can help agents in real-time while on the call. It's as if the manager is behind an agent, helping and telling that agent what to say and hearing what the customer says. Agent Assist lets you support every agent automatically, in a more scalable way, without listening to every call. Five9 also comes with WorkFlow Automation or Studio Flow, a nice feature because it's drag-and-drop, where even a non-engineer can build out a campaign and have different aspects to the campaign, for example, call routing. In the past, you had to be an engineer to build campaigns in Five9 or get on a call with the Five9 team and ask the team to make the changes, but nowadays, it's drag-and-drop, which is very helpful. I've also used the Workforce Optimization feature in Five9, though not as much. Still, I'm familiar with some of its capabilities, such as optimizing the time of day or days of the week when your team's the busiest, making optimizations when you don't need as many reps, or when you need more reps in place to match the bandwidth of calls coming in. Definitely, Workforce Optimization is beneficial and essential for my customers nowadays. Five9 can integrate with various CRMs, and I find that essential. The solution has an endless list of integrations for a reason, but I wasn't the guy who built the integrations. I heard that CRMs could be hard to work with, but the CRMs I've experienced with Five9, such as Salesforce and Hubspot, seem to integrate well. There was one really bad CRM built in-house on a platform called PPMS, but it's basically an internal tool, which was a little hard to work with and challenging to make changes, but it worked, though my Salesforce customers seem to be happy with the solution. The Omnichannel capability of Five9 is also essential, as the customer expects you to have chat, text, Facebook Messenger, and all other ways a customer can reach the reps. The omnichannel feature in Five9 is essential to customers.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The technical support services are good."
"It's scalable, it's fast, and it is very robust."
"Before using the WFO and its analytics, our quality teams would listen to only 5 percent of contacts a week, per employee, which is a very small part of what an employee is doing... Now, this tool does an automatic evaluation of 100 percent of their calls. It has certainly helped the QA teams in their training, and that, in turn, helps our clients."
"The product’s IVR script editor is very easy and simple to use."
"Five9 has a lot of AI tools, which I find valuable. It offers transcription services and a power dialer for outbound dialing. I like that Five9 is built for outbound and suitable for that purpose."
"Queue callback, agent skill-based routing, call reporting, and the flexibility to log in from anywhere are some of the most valuable features for our organization."
"It helped reduce costs in our organization. We've saved on staffing and we've saved on software by 10% to 15%."
"I'm interested in all the features we're using and the reporting that's needed to get them up and running."
"The most valuable feature is the simplicity of making scripts within the contact center solution itself."
"The admin platform is easy to use and navigate. That has been incredibly useful for us because it has given us the ability to self-provision in a lot of situations. The ability to create and track data elements has also been a valuable addition."
 

Cons

"The solution should be more flexible on-premises. We are currently on-premises and looking to move to the cloud."
"Its scalability means that it is not a simple 'install and forget' setup."
"During training and demos, resiliency tests failed, which was not ideal. This is a concern for stability."
"Five9 should provide free training resources for end users, including agents, supervisors, and admins."
"Five9's stability needs to be improved."
"I rate Five9 support five out of 10. My experience with Five9 support has been mixed. It's good at times but not particularly helpful sometimes."
"There are several audio issues that need attention. Whenever I disconnect a headset after connecting to the VDI, the station connection in Five9 disconnects automatically, requiring a VMware restart."
"Downtime happens occasionally, about two days a month, likely because of heavy usage by many agents, but I have not faced that issue as a supervisor."
"There are some minor issues with some of their filtering that I'd like them to handle on their back end. The only limitation I can think of is that I'm always looking backward and can't look forward. I can't see how many calls are scheduled for tomorrow based on our system."
"There have also been some challenges in being able to keep the format of an original email. The solution acts as a proxy, but it's not bringing over the full format that the email came in with... Five9's email channel isn't as good as some other vendors' email channels that I've seen. But there is an upgrade coming..."
 

Pricing and Cost Advice

"Avaya Contact Center solutions might not be the cheapest solution available (but you certainly get what you pay for)."
"Their license structure, out of the box, is better than that of other providers and their pricing is much less than other vendors we've looked at."
"The product's pricing is flexible and reasonable."
"The pricing seems reasonable. I had anticipated that whatever solution we went with would be more expensive. I was actually pleasantly surprised that the features that we had in Evolve IP, one-to-one, did not cost significantly more in Five9."
"Five9 is expensive, but most companies would find that using it is worth the cost."
"Five9 is reasonable."
"Five9 is a little expensive because of our company's size. That said, it scales pretty well. The daily usage costs and monthly fees seem about right. It's not out of line with what we'd expect from other companies. However, they seem to have a one-size-fits-all implementation fee. Most of their clients have hundreds if not thousands of seats in the call centers, so $5,000 or $10,000 is not a huge cost. It would be nice if they had a sliding scale for smaller companies."
"The product is not the most expensive, but it's not cheap."
"Five9's pricing wasn't quite as flexible as I'd hoped, but it ended up being reasonably priced overall."
