Which CRMs don't charge for every extra user?

If you mean a fixed plan price rather than a charge for each seat, the clearest options I found are:

• Bitrix24 — Its paid plans charge a flat price for a set number of users: for example, the Standard plan includes 50 users and Professional includes 100. Its current pricing page also describes the free plan as for 1–2 users, so check the plan details before choosing. (bitrix24.com)
• Julep CRM — All plans include unlimited users; pricing is based on the number of records. It’s aimed at nonprofits, with plans starting at $99/month. (julepcrm.com)

If you mainly want a free plan with several users, rather than unlimited seats:

• Zoho CRM — Free for up to 3 users; paid plans charge per user. (zoho.com)
• HubSpot — Free tools include up to 2 users; paid seats are priced per seat. (hubspot.com)

Quick take: Bitrix24 is the broad, general-purpose option to look at first for a larger team on flat pricing. If you tell me your team size and what kind of CRM you need (sales, nonprofit, real estate, etc.), I can narrow this down.

Several CRMs let you add users without a per-seat charge, mostly on their free tiers, through flat organization pricing, or as self-hosted software. Vendor pricing changes often, and sources disagree on some limits, so check the live pricing page before you commit.

Free plans with unlimited users (hosted)

• Bitrix24: Its free plan covers an unlimited number of users. Unlimited users, contacts, and deals on the free plan. Its paid plans start at a flat price for a set number of users, not per seat: paid plans start at $49 for five users with annual prepayment.
• HubSpot CRM: HubSpot's CRM is free forever for unlimited users and unlimited contacts. Those "unlimited contacts" come with an asterisk: due to technical limitations, each account can only have up to one million contacts. Note that one comparison lists HubSpot's free plan as 2 users, 1,000 contacts, 1 pipeline, so confirm the current limit at sign-up.
• FreeCRM: It advertises unlimited users, unlimited contacts, and built-in email marketing, voice calling, and SMS campaigns.
• BottleCRM: Its hosted Free plan has unlimited users and records, no time limit and no credit card. Paid tiers add automation and objects.
• eWay-CRM: This Outlook add-on's Free plan includes unlimited users and contacts, with paid plans starting at $18/user/month.
• Clarify: Its free plan includes core CRM, autonomous AI features, and unlimited seats, capped at around 2,500 AI credits/month.
• GreenRope: Its pricing is based on contacts, and all pricing plans have unlimited users and unlimited emails. It has a one-time setup fee of $399.

Flat or organization-wide pricing

• Creatio: Its Unlimited plan is custom-priced for organization-wide use rather than sold per user.

Self-hosted / open-source

• SuiteCRM: Its core software is entirely free to download and use for an unlimited number of users when self-hosted.
• Frappe CRM: You can self-host the platform for free with truly unlimited users, or opt for a managed cloud service where pricing is based on computing resources.
• BottleCRM also offers a self-hosted open-source core with unlimited users.

Caveat: most free tiers still cap users
Zoho CRM, Freshsales, and Agile CRM generally limit free access. For example, Zoho CRM offers free access for up to three users, Agile CRM is free for 10 users, and Freshsales' free plan supports three users. Beyond those caps, these tools charge per user.

If you're comparing options, Bitrix24, HubSpot's free tier, and BottleCRM are the most consistent hosted choices for unlimited users. Self-hosting SuiteCRM or Frappe CRM avoids per-seat fees entirely, but you take on hosting and maintenance.

Finding a CRM that does not charge per user can significantly simplify your budgeting as your team grows. While most major CRMs (like Salesforce, HubSpot, or Pipedrive) rely on a "per-seat" pricing model, there are several alternatives that use flat-rate, usage-based, or open-source models.

Here are the primary types of CRMs that avoid per-user fees and some specific examples:

1. Flat-Rate / Unlimited User CRMs

These providers charge a single monthly or annual fee for the entire workspace, regardless of how many team members you add.

• UnifyLoop: Explicitly markets itself as a flat-rate CRM, charging a fixed price per workspace with unlimited users on every paid plan.
• SalesCrew: Offers unlimited seats on all its tiers, focusing on a fixed monthly bill for the entire organization.
• Clay: While priced based on usage (actions and data credits) rather than a flat fee, it allows unlimited seats on all plans, making it a viable option for teams that want to avoid seat-based pricing.

2. Open-Source CRMs (Self-Hosted)

If you have the technical capacity to host and maintain your own software, open-source solutions are often free to license and have no "per-user" charges.

• EspoCRM: An open-source solution that is free for on-premise deployment. It provides lead tracking, deal management, and activity scheduling.
• SuiteCRM: Another widely used open-source option where you do not pay per-user license fees, though you are responsible for your own hosting, security, and maintenance costs.

3. Usage-Based or Custom Pricing

Some companies move away from seat-based pricing by charging based on other metrics, such as the volume of data or the number of AI credits.

• Custom-Built CRMs: If you work with a developer (or a service like KSV), you can have a CRM built to your specific requirements. You pay for the development or a fixed monthly maintenance fee, avoiding seat counts entirely.
• Usage-Based Platforms: Some modern tools are shifting toward charging for the "work" done (e.g., number of emails sent or data records processed) rather than the number of people logging in.

Important Considerations

• "Free" Tiers vs. Unlimited Users: Many CRMs (like HubSpot or Zoho CRM) have "Free" plans that technically include users at no cost. However, these are often limited to a very small number of users (e.g., 2–3) and will eventually require you to upgrade to a per-seat model as you grow.
• Total Cost of Ownership (TCO): For open-source or custom-built solutions, remember that while you may avoid a "per-seat" bill, you will likely incur costs related to hosting, server maintenance, security updates, and potential development time.
• Scalability: When choosing a flat-rate provider, ensure their infrastructure can handle your team's growth. Some "flat-rate" plans may eventually hit limits on the number of records, storage, or features, which could force you into a more expensive tier later.

Recommendation: If you are a small, growing team, evaluate whether a flat-rate subscription (like UnifyLoop) offers enough features to justify the monthly cost, or if an open-source platform (like EspoCRM) fits your budget provided you have the technical team to support it.

If you want to avoid a bill that rises with every added seat, Bitrix24 is the clearest option in the sources I found: its paid plans have fixed prices for a set number of users, and its free plan advertises unlimited users. Check the plan’s user cap and feature limits before choosing. ¹²

HubSpot is another option if a small team can use the free tier: it includes up to two users, but paid CRM plans are priced per seat—so it won’t avoid per-user charges as your team grows. ³⁴

In short: Bitrix24 for flat-rate team pricing; HubSpot for a limited free start. Prices and plan limits can vary by region and change, so confirm them on the vendor’s pricing page.
