A Five9 customer works inside a domain, the configuration space that holds users, skills, campaigns and licences. The licensing that matters in daily operation is the domain’s quantity limits: licensed agents, supervisors, inbound and outbound lines, and a set of other objects. Five9’s knowledge base explains how those limits behave, and the public pricing page says that bundle prices are per concurrent user.[6] This article describes what is documented about counting and enforcement, and where the documentation stops.
Editions
Concurrency behaves the same across the Digital, Core, Plus, Pro and Enterprise bundles, which share the per concurrent user basis described on the pricing page.[6] The administrator guide adds that Agent Desktop Plus settings are available if the domain is licensed for Agent Desktop Plus, and that chat, email and social reporting is available only when the domain is licensed for text channels.[5] See Agent Desktop Plus is a licensed domain feature and Social reports need a text-channel licence. The pricing page notes that a voice seat includes Agent Desktop Plus, so the desktop is counted within the seat on the bundle page.[6] The editions article, Five9 licensing, lists the bundles.
Metrics
Concurrent agent seat
Five9’s blog defines concurrent seat licensing as a model in which a licence can be shared in a one-to-multiple ratio, so multiple human agents can use one application licence during a 24-hour period.[7] For example, a customer with three non-overlapping shifts of 50 agents each could need roughly 50 concurrent seats rather than 150 named ones, subject to its order. The blog concludes that for stable workforces an unlimited concurrent licence is usually the most cost-effective model.[7] See Concurrent agent seat and Concurrent seat licensing lets many agents share one licence.
The count is enforced at login. Five9 gives the example of a domain with 10 licences and 10 agents logged in at the same time: the 11th agent that tries to log in receives an error message such as “The maximum agent count has been reached”, with a variant for Agent Desktop Plus.[1] The article states that the error appears when the limit set in the domain has been reached.[1] The consequence for compliance is that the platform itself prevents agents from exceeding the licensed concurrent count, so an over-deployment shows up as blocked agents, not as a later invoice. See The licence limit blocks the next agent at login.
The administrator guide adds a second control: the number of users that can be added, regardless of role, is determined by the licence.[5] See The number of users is determined by the licence. Combined with the login limit, this means both the account list and simultaneous use are bounded by the order.
Named agents
Where a customer buys on a named basis, the licence follows the person. Five9 states that it prices on concurrent users, named agents or pay per use, that WEM is offered on a named basis, and that named seats beyond the concurrent seats sold are sold as add-ons.[6] The blog adds that for part-time agents a named licence can cost more than the work warrants, so concurrent or usage-based models may fit better.[7] See Named agent and Named licences cost more for part-time agents.
Supervisor licences
Supervisors are licensed separately. Five9 says supervisor roles can be assigned to any number of users in the administration console, even beyond the licence limit, but the licence still limits the supervisors who can be logged in at once, and the error “The maximum supervisor count has been reached” is among those listed.[1] The supervisor licence is “no longer free of charge”, and additional licences are requested through the Customer Success Manager or Five9 Sales.[1] The Account tab does not show the supervisor licence count; Five9 says to ask the Customer Success Manager or Support.[2] See Supervisor licence, Supervisor roles may be assigned beyond the licence number, The supervisor licence is no longer free of charge and Supervisor licences are checked with the Customer Success Manager.
Lines
The Account tab shows “Agents licensed” and “Max Inbound/Outbound Lines” when a Partition Admin logs in to the Five9 website.[2] A Five9 moderator confirmed in the community that inbound lines are used when a caller successfully connects to the inbound campaign, even if the caller is still in the IVR, so queue and IVR time consumes line capacity as well as agent talk time.[4] The administrator guide describes the outbound side: a domain setting reserves a share of outbound lines from automated campaigns so agents can still make transfers, callbacks and manual calls. New accounts default to 95% for automated campaign calls, and the minimum possible setting is 25%.[5] See Inbound and outbound lines, Inbound lines are used while a caller is still in the IVR and New domains reserve 5% of outbound lines from automated campaigns.
Counting and floors
Measuring peak concurrency
Because enforcement is automatic, the practical question is whether the licensed number is right. Five9 documents a custom report that gives a close estimate of concurrent agent licence use. It uses a Matrix report on the Agent type, with Agent and Hour as columns, a distinct count of agents and a criterion of the Login agent state.[3]
The article cautions that the report is only an estimate. It counts every agent logged in during each hour based on agent state, so an agent who logs out at 4:02 and is replaced by another at 4:05 is still counted as logged in for the whole 4:00 hour, which overstates simultaneous use. Five9 suggests ordering by quarter hour for a closer estimate, with the same limitation within each 15-minute bin.[3] See The concurrent agent report is an estimate and Hourly reporting overcounts logged-out agents. For capacity planning the overstatement is conservative, but for true-down negotiations it may understate the case for fewer seats, so the raw agent-state data should be exported where possible.
Floors
The public page gives a minimum of 50 seats for the per concurrent user prices and says usage-based pricing may apply.[6] See Bundle prices are per concurrent user with a 50-seat minimum and Fifty-seat minimum. Five9 does not publish any right to reduce seats mid-term, term lengths or notice periods, so reductions should be negotiated into the order.
Other domain limits
The same knowledge-base article lists other limits that Five9 support can raise when reached: maximum running campaigns, call fields, skill groups, conferences, CRM fields, custom reports and scheduled reports.[1] These are configuration ceilings and not billed metrics in the public documents, but a customer that needs more should expect to raise them with its Customer Success Manager. See Support can raise other domain object limits.
Programs
Two programs affect how a customer licenses concurrency. The 50-seat minimum is a commitment floor for the published prices. Usage-based pricing, called per-minute pricing by Five9, is an alternative that the blog recommends for seasonal peaks, part-time agents and BPO billing, while recommending unlimited concurrent licences for stable multi-shift teams, for which it says usage pricing may cost about double for a full-time agent on voice calls for 80% of productive time.[7] See Usage-based pricing option and Five9 offers per-minute pricing alongside concurrent licences.
Out of scope
This article does not cover seat reduction rights, renewal terms or audit rights, which are in the unpublished customer agreement, nor the pricing of add-ons described in AI and workforce engagement licensing.
Compliance checklist
- Read “Agents licensed” and “Max Inbound/Outbound Lines” from the Account tab and compare with the order.
- Ask the Customer Success Manager for the supervisor licence count.
- Run the distinct agent login report by quarter hour for a representative busy period.
- Count blocked login events and campaign-start errors as evidence of under-licensing.
- Review the outbound line reserve setting against campaign dialing modes.
