Texting platforms usually handle users in one of two ways: a set number of users or seats, with more at added cost, or unlimited users on every plan. The model decides who on your team can text customers. If many people need access, or your team is growing, an unlimited-user plan avoids rationing logins. Sakari includes unlimited users and contacts on every plan.
User limits rarely get much attention during a software evaluation. Teams compare features, integrations, and message volume, then pick the plan that fits the people texting today. It feels like a minor detail, the kind of thing you can sort out later.
Months later, that detail has quietly shaped how the whole channel works. It decides who gets a login and who borrows one, whether a manager can see what the team is saying to customers, and whether a new department can start texting next week or has to wait for the next budget cycle. This guide looks at the two common models, how seat limits change behavior in ways nobody plans for, and the questions to ask so your plan fits the team you will have, not just the team you have now.
Consider a property management company that started texting with a single seat. The leasing manager, Jordan, used it to confirm showings and answer questions from prospective tenants. It worked so well that the maintenance coordinator asked to use it too. Then the after-hours on-call staff. Then two assistant property managers.
Adding a seat for each of them felt like a lot to justify for a few texts a day, so everyone shared Jordan's login. For a while, that seemed fine.
Then a tenant complained that someone had promised a repair date that never happened. Jordan could see the message in the history, but not who sent it. Two people thought they had replied to a different tenant's question, and neither had. And when one of the assistant managers left, the team realized the password had been written on a sticky note at the front desk for months.
Nobody made a bad decision. The plan simply did not match how the team actually worked, so the team adapted around it. That pattern is common, and it is worth understanding before you choose a plan.
Per-user (seat-based) plans include a set number of users. Adding someone means adding a seat, and sometimes moving to a different plan. The model is common across business software, so it feels familiar and easy to compare.
Unlimited-user plans give everyone who needs access a login. Instead of users, plans are usually based on other factors, such as messaging volume or features.
Neither model is wrong. A per-user plan can be a perfectly good fit for one person who texts occasionally. The right choice depends on how many people will touch customer conversations, both today and a year from now. That second part is where most teams underestimate.
When every new user adds cost, teams find ways around it. The workarounds are understandable, and each one creates a problem that is hard to see until it surfaces in front of a customer.
The most common is the shared login, the path Jordan's team took. Several people use one account, so nobody can tell who sent what, managers cannot coach individuals, and when someone leaves, the password has to change for everyone.
Not far behind is the gatekeeper: one person who relays messages for everyone else. Customers wait while their question is passed along, and during busy periods the gatekeeper becomes a bottleneck.
Then there are personal phones. When the business tool is hard to get into, people text customers from their own numbers. The conversation lives on a personal device, the customer now has an employee's personal number, and when that employee leaves, the history and the relationship leave with them.
Some teams settle for partial access. Sales gets seats, but support, scheduling, or account management does not, so customers get fast answers from one department and silence from another.
And some simply delay. A department that would benefit from texting waits because the seat math is hard to justify, and the channel never reaches its full potential.
Each workaround chips away at accountability, response time, or record keeping. Together, they can turn a useful channel into a liability.
The best way to avoid those workarounds is to count everyone who will send or answer texts, not just today's core user. The list is usually longer than people expect.
It typically starts with sales reps and SDRs following up with leads and customers, and support agents answering questions. Schedulers and coordinators need access to confirm and reschedule appointments. Account managers check in with existing customers. Field staff update customers on arrival times or job status. Managers review conversations and cover when someone is out. And in many businesses, seasonal or part-time staff join during busy periods.
A team that starts with two people texting often grows well beyond that once other departments see what texting can do. Planning for that growth up front is far easier than unwinding workarounds later.
Most teams do not decide to outgrow a texting plan. It happens gradually, and the signs are easy to miss because each one looks like a small, separate issue.
Watch for a login that several people know the password to, or a teammate who regularly asks someone else to "send this for me." Notice when customers mention texting an employee's personal number, or when a department that clearly needs texting is still waiting for access. Pay attention when a manager cannot answer a simple question like "who told this customer that?" without asking around.
Any one of these is manageable. Two or three together usually mean the plan is shaping the team, instead of the other way around. That is a good moment to revisit how your platform handles users.
Here is how the two models compare on the situations teams run into most often.
| Per-user plans | Unlimited-user plans | |
|---|---|---|
| Who can text | People with a seat | Everyone who needs access |
| Adding a teammate | Add a seat | Create a login |
| Seasonal staff | Add and remove seats | Add and remove logins |
| Accountability | Breaks down if logins are shared | Each person has their own login |
| Manager visibility | Only if managers have seats | Managers can have their own access |
| Expanding to new departments | Requires another purchase decision | Requires a setup decision |
| Best fit | One or two dedicated users | Teams and growing organizations |
Per-user plans can work well when one or two people handle all texting, the team size is stable, texting is occasional rather than part of daily work, and nobody else needs to see the conversations.
Unlimited-user plans fit better when several departments text customers, when the team is growing or changes with the seasons, when every conversation should stay on business numbers in one inbox, and when managers need visibility to coach, review, and cover. They also remove the friction of expanding, since giving a new department access becomes a setup task instead of a purchase decision.
Giving everyone a login solves the access problem, but it creates a new question: how do you keep a busy inbox organized? The user model is only half of the decision. These features decide whether team texting actually works once more people are in it.
The first is a shared inbox with assignment. When many people can see conversations, each one needs a clear owner, or two people answer the same customer while another goes unanswered. The second is control over numbers. Teams often use different numbers for sales, support, or locations, and each group should see the numbers it uses. The third is CRM logging, so history stays with the customer record instead of the person who sent the message. That is what keeps handoffs smooth when someone is out or leaves. Finally, mobile access lets field staff and managers reply from a phone without using a personal number, and after-hours coverage sets expectations when nobody is available.
Teams that expand texting smoothly tend to grow in deliberate steps rather than all at once.
They begin with the team that texts most, usually sales or scheduling, and set clear ownership rules: how conversations are assigned, and what happens when an owner is out. Numbers are organized by team so each group sees what it needs. The CRM is connected early, so every conversation logs to the customer record from the start. Shared templates give everyone consistent answers to common questions.
With that foundation in place, the next department joins. Support, account management, and field staff are common next steps. From there, a regular review of unanswered conversations and response times keeps the system healthy as it grows.
Sakari includes unlimited users and contacts on every plan, so access is never the thing holding a team back. The rest of the platform is built for what happens next. The shared inbox supports conversation assignment, so each conversation has an owner. Phone number groups give each team access to the numbers it needs. Web, iOS, and Android apps keep people away from a desk on business numbers. Native integrations with HubSpot, Pipedrive, ActiveCampaign, Intercom, and Aircall log conversations where your team already works. And Sakari AI provides automated replies and office-hours routing for messages that arrive after hours.

When Jordan's company revisited its plan, the first step was simply giving everyone their own login. Shared passwords disappeared overnight, and so did the question of who sent what.
The second step mattered just as much. Leasing, maintenance, and on-call each got their own number group, so tenants' repair requests stopped mixing with showing confirmations. Conversations were assigned to the person handling them, and history logged to each tenant's record. When the next assistant manager left, nothing left with them.
The team did not text more because it had more logins. It texted better, because the plan finally matched the way the team worked.
Whatever platform you consider, these questions will show how its user model will play out in practice:
What does unlimited users mean on a texting platform? It means everyone who needs access can have their own login without adding a per-user cost. Sakari includes unlimited users and contacts on every plan.
Why does the user model matter for team texting? Seat limits often lead to shared logins or texting from personal phones, which breaks accountability and conversation history.
Can I control which users see which numbers? In Sakari, phone number groups let you give each team access to the numbers it needs.
Can conversations be assigned to specific people? Yes. Sakari's shared inbox lets you assign conversations to specific team members.
Does Sakari limit the number of contacts? No. Sakari includes unlimited contacts on every plan.
