Hidden Costs Breakdown

1

Implementation and Onboarding Fees

high implementation

Five9 charges significant upfront implementation fees separate from monthly subscription costs. This includes system setup, configuration, and initial training.

Genesys Cloud publishes their pricing. At about $80 per seat, that will run you $5-7k per month. If it's simple... Implementation would run $30k. That's your budgetary number. Five9 costs about the same

2

System Initiation Fee

medium implementation

High upfront initiation fee required before system activation, charged on top of monthly subscription and implementation costs.

Five9 (around $250/agent/month all-in which isn't that bad, high upfront initiation fee of ~$2,500+)

Automated Texting Requires Separate Platform (Acqueon)

critical addon

Automated texting workflows are not included in Five9. Basic CSV text blasts and manual one-on-one texting are included, but any workflow automation (send text on day 1, different text on day 2) requires purchasing a completely separate phone system called Acqueon, more than doubling total costs.

trustpilot

Sales team at Five9 mislead us to believe automated texting is included with Five9. It's not! On the last day of onboarding they finally admitted that Five9 has no automated text capabilities. Only then did they explain that the texting shown in our order just gives us the ability is to upload a CSV and send a text blast or do manual one-on-one texting. That's it! Can get more features from almost any other phone system out there. Five9 cannot do even a basic workflow like, send this text on day one, this other text on day two. None of that is possible. Later they will try to sell you a whole 2nd phone system called Acqueon, which more than doubles the cost.

Premium Features Billed Separately Despite Promises

critical addon

Features promised during sales process often require additional charges or are not delivered at all. Multiple users report being billed for work never performed and features that didn't materialize.

trustpilot

Could not be worse. Most features promised didn't materialize. The ones that did were half of promised and wanted to charge more for. Never got launched and they want to charge us $80k to part ways after they never delivered.

trustpilot

We never received any of the work promised in our SOW, but they were more than happy to threaten legal action over non-payment on work never performed. Yes, you read that correctly - they want payment for work never performed.

5

Infrastructure Requirements (No WiFi Support)

medium implementation

Five9 does not support wireless connections, requiring wired ethernet infrastructure for all users, adding deployment costs for remote or flexible workspaces.

trustpilot

This has got to be the worst piece of software I've used in my 10+ years of working in IT. First of all, they don't offer support for wireless connection...i.e WIFI. What year is it where WiFi is not supported?
