Best CRM for agencies running outbound for clients (2026)

An agency running outbound for clients needs a CRM that keeps each client's contacts apart, shows conversations from every channel in one place, reports meetings held per client and lets the client see only their own. This post lists what to require, four options with prices read from their own pages on 25 October 2026, and where Sellinger's built in CRM fits. We make one of the four, so we mark where our view is not neutral.

What should an agency require from a CRM?

1. Separate data per client. Each client's leads, notes and history in their own space. A shared list is how a message goes to the wrong person.
2. One inbox across channels. LinkedIn, email and WhatsApp replies in one thread per person, so nobody answers the same lead twice.
3. Meetings held, per client. The number you report. Booked is not held; see count meetings honestly.
4. Scoped client access. Clients view results or work in their own space without seeing other clients, your pricing or your other accounts.
5. Your brand. For many agencies the client should log in to the agency's name.
6. Cost that does not scale with your headcount. Per seat pricing grows when you add people to cover clients.

A CRM that is strong on pipeline stages but weak on separate clients and channel inboxes is a poor fit.

Which options are there, and what do they list?

HubSpot. The pricing page lists free tools at $0 a month, free for up to 2 users with no credit card required, and Sales Hub Starter "starting at $7/mo/seat" shown next to $20/mo/seat; the page does not say which figure applies to which billing choice (HubSpot, read 25 October 2026). A familiar CRM for clients who already use it. How an agency keeps clients apart in it is not on the page we read, so ask HubSpot.

GoHighLevel. Starter $97 a month with 3 sub-accounts, Unlimited $297 with unlimited sub-accounts and basic API access, Agency Pro $497 with SaaS Mode and automated sub-account creation. CRM and pipelines and workflow automation are listed as core features, with usage fees for phone, text message, email and AI on top, and a 14 day trial (GoHighLevel, read 25 October 2026). Built for agencies, with sub-accounts as the unit of client separation. See GoHighLevel vs a white label AI SDR.

Close. Per user a month: Solo $9, Essentials $35, Growth $99, Scale $139, each shown with a higher crossed out price ($19, $49, $109, $149) and the page does not say which billing cycle the discount applies to. Calling and texting are built in and billed by usage (Close, read 25 October 2026). The page presents calling and texting as built in; it is priced per user, so an agency adds cost with each person.

Sellinger's built in CRM. Contacts, deals and the full conversation history across channels, with a two way sync to HubSpot. It comes with the agents rather than as a separate product: LinkedIn $198 per agent, other channels from $19 to $39 a month, bundles $249 to $1,199 (pricing). For agencies, the white label program is a one time $500 setup fee, then the standard agent prices, with a portal on your own domain and unlimited clients with scoped access (partners). It is an outbound product first; it is not a general purpose CRM for a client's whole business.

How do they compare against the requirements?

"Not checked" means we did not verify it on the vendor's page and make no claim. Ask each vendor, because the answer decides the fit.

What does an agency lose or gain with each?

HubSpot gains familiarity, and clients may already use it. Whether it separates clients and covers outbound channels the way you need is for you to check with HubSpot.

GoHighLevel gains breadth. One platform for the client's CRM, funnels and automations. It loses focus: building and watching outbound sequences is your work.

Close gains a sales team CRM with built in calling and texting, per its page. It is priced per user, so cost grows with each person you add; check how it separates clients.

Sellinger gains the outbound itself: the agent researches, writes, follows up, answers and books, and the CRM stores the result. It loses if you want one platform for everything else a client does.

How should you choose?

• Outbound is your only service: an AI SDR with a built in CRM keeps the stack small.
• You sell several services and outbound is one: a platform such as GoHighLevel for the rest, and a specialised outbound tool, with one system speaking per prospect.
• Clients already live in HubSpot: use a tool that syncs with it, so meetings land where the client looks. Sellinger does this in both directions.
• You are a one person agency: start with the cheapest option that separates clients, and re-check at five clients.

A short test before you commit

1. Set up two fake clients.
2. Add five contacts to each.
3. Check that nobody on one can see the other.
4. Send a test reply on each channel you use and see where it lands.
5. Pull a "meetings held" number for each client in under five minutes.

If a tool fails any of the five, it will cost you time every week. For a wider list, see the best AI CRM tools, and for the agency launch plan, how to launch a white label AI SDR service.

What does it cost for a realistic agency?

This is a made up example to show the method, not a quote. An agency has four clients and two people. For each option, write down the monthly cost of the plan, the usage fees you expect, and the hours your people spend each month on setup and tuning for each client.

• With a per user CRM, the plan cost scales with the two people, and does not change when you add a fifth client, but your time per client stays.
• With a platform plan that includes sub-accounts, the plan cost stays flat as clients grow, usage fees grow with volume, and the time is mostly yours.
• With an AI SDR program, the plan cost is the agent prices for each client's modules, the setup fee is paid once, and the time per client falls because the agent writes and follows up.

Multiply your hours by your own hourly cost. In most agencies that number is larger than the plan price, which is why the question "who does the work?" matters more than the price on the page.

What should you ask a vendor?

• Can each client's data be kept apart, and how?
• What does a client see, and can I limit it?
• How are usage fees calculated, and where can I see them per client?
• What happens to client data if I leave?
• Can I export every conversation?

Write the answers down with the date. Vendors change their terms, and so do we.
