Groundbase vs Close.com — the indie alternative to a sales-team CRM

Close is the CRM that sales teams reach for when phone-and-SMS outreach is the whole game. Built-in dialer, voicemail drop, automated workflows, deep call recording — it's optimized for sales reps making 50-200 calls a day.

It's also the closest competitor to Groundbase architecturally, because both products treat phone and SMS as core, not bolt-ons. The differences come down to who the product is shaped for and how the telephony economics work.

This is the honest comparison.

What Close does well

Want to be fair — Close is a legitimately well-built product for its target audience:

• The dialer experience is excellent. Power Dialer in higher tiers auto-advances through a list of contacts, saving real time for high-volume callers. The integration between contact records and the live call is smooth.
• Voicemail Drop is built in. Pre-record a voicemail, let the system drop it after the beep. Saves repeating yourself across 100 cold calls.
• Call recording + 30-90 day retention. Recordings live with the contact, searchable.
• Mature sales-team features. Roles + permissions, lead visibility controls, leaderboards, custom activities, automated workflows.
• Email + SMS in the same UI as calling. No tab-switching between tools for outreach.
• Solid AI features in higher tiers. AI email assistant, transcripts via the Call Assistant add-on.

If you're a sales team making heavy phone volume, Close is a serious tool and deserves the consideration.

The pricing structure

As of writing (verify on close.com for current numbers), Close's monthly tiers are:

| Tier | Monthly billing | Annual billing | What's notable | |---|---|---|---| | Solo | $19/seat | $9/seat | 1 user only, up to 10,000 leads, no Power Dialer, no Voicemail Drop | | Essentials | $49/seat | $35/seat | Adds team features; still no Power Dialer | | Growth | $109/seat | $99/seat | Power Dialer + Voicemail Drop unlock here | | Scale | $149/seat | $139/seat | Adds unlimited recordings, AI email assistant |

Plus optional add-ons:

• Call Assistant (AI transcripts + summaries): $50/month + $0.02 per minute of recorded calls

There's also a credit system: 500-2,000 credits per user/per month included depending on tier, with calling and SMS deducting from those credits at Close's per-message rates.

The headline gap: Power Dialer is gated to Growth+

This is the structural critique. If you're a solo operator who actually wants the Power Dialer — the feature that justifies a sales-focused CRM — the cheapest tier that includes it is Growth at $109/seat/month monthly billing.

For one user doing volume cold-call work, that's:

• Close Growth: $109/month × 12 = $1,308/year
• Groundbase: $9/month × 12 = $108/year

That's a 12x cost difference at the tier where Close's signature dialer feature actually exists.

The cheaper tiers (Solo at $19, Essentials at $49) are less interesting for the volume-calling use case Close advertises, because without the Power Dialer you're manually clicking each contact — which is exactly the workflow Close's marketing tells you to escape.

Where Close wins fair and square

I want to be honest about this, because Close has real features Groundbase doesn't:

Power Dialer

Groundbase doesn't have an auto-advance dialer yet. If you live in cold-call volume mode — 100+ dials per session — Close's Power Dialer is a real productivity unlock and Groundbase can't match it on this specific dimension. You'd manually click each contact to dial through Groundbase's softphone.

This is a real gap. I'm not going to pretend it isn't. For sales reps making 100+ dials a day, Close's dialer alone might be worth the price difference. I've parked Power Dialer as a future feature, but it's not in Groundbase today.

Voicemail Drop on every call

Close's voicemail drop is integrated into every call session for users on Growth+. Groundbase has voicemail drop but it's more limited in current scope.

Mature team features

Roles, permissions, leaderboards, lead routing — all built in. Useful if you have a sales team. Groundbase doesn't bother with these because it assumes you're alone.

Built-in telephony "just works"

You don't need to bring your own Twilio. Sign up, get a number from Close, start calling. Lower setup friction (at higher cost-per-call).

Where Groundbase wins

BYO Twilio — your cost-per-call is what Twilio charges

This is the architectural disagreement that defines the rest. Close uses bundled telephony — they're the middleman between you and the carriers. The credits system + per-minute rates include their markup.

Groundbase: you connect your own Twilio account. Your per-message cost is whatever Twilio's actual price is (about $0.0075 per SMS in the US, $0.013/min for voice). No platform markup.

For anyone running real outreach volume, this is the difference between profitable outreach and not. A solo operator sending 5,000 SMS a month pays $37.50 with Groundbase + Twilio direct, vs whatever Close marks it up to with their credits. Over a year, the spread compounds.

(I wrote about why I deliberately moved Groundbase to BYO Twilio — short version: the credits markup model carries hidden complexity that's not worth the few cents of margin per message.)

Flat $9/month, no tiers

Everything Groundbase has is in the flat plan. Drip sequences, calendar, MCP integration, custom fields, tags, contacts, deals, voice, SMS — all included. No "upgrade to Growth to unlock X" tier pressure.

MCP support — your AI can drive the CRM

Groundbase exposes itself as a Model Context Protocol server. Claude Desktop, Cursor, Windsurf, Cline, or any MCP client can read and modify your CRM data directly. Ask your AI to "draft personalized SMS to everyone tagged 'demo-requested' who hasn't been contacted in 7 days" and it'll do it via your real data. Close doesn't have this.

(Why MCP matters as a feature — full piece.)

Built for one operator, not for teams

No deal owner field cluttering every record. No lead routing setup. No team permission scaffolding to ignore. The UI assumes you're the one doing the work.

No upgrade trap

Close's pricing is structured to grow with you — more seats, more features, more cost. Groundbase has no upgrade path. $9 today, $9 forever (at one user).

The actual decision

Pick Close if:

• You're a sales team (or growing into one) doing high-volume cold calls
• The Power Dialer + Voicemail Drop combo is a workflow you live in
• You'd rather pay bundled telephony than connect your own Twilio account
• You need team features (roles, leaderboards, permissions, lead routing)
• The $109-149/seat/month cost is justified by call volume × close rate

Pick Groundbase if:

• You're solo and staying solo
• You care more about cost-per-message than auto-dial workflow
• You'd rather connect your own Twilio than pay platform markup
• You want your AI tools to talk to your CRM directly via MCP
• The flat $9/month vs per-seat-tiered pricing matters to your math

The honest middle case

Some people fall in between — solo founders who DO make a lot of cold calls and would benefit from a Power Dialer. For that user, today, Close is genuinely a better fit despite the cost. I'm not going to pretend otherwise.

The trade-off: you pay Close $109/month for the dialer convenience, or you pay Groundbase $9/month and manually click each contact while saving $1,200/year. If your volume is high enough that the dialer saves you hours per week, Close pays for itself. If not, Groundbase + manual dialing is the better economic call.

Power Dialer is on the Groundbase roadmap — but I'm building it driven by customer demand rather than competitive FOMO, so it's not in the product today.

Try it

Groundbase is $9/month flat with a 14-day trial. Card required at trial start, nothing charged until day 15.

If you're making 100+ cold calls a day and the Power Dialer is core to your workflow, Close's pricing is justified for your use case. If you're a solo operator with mixed-mode outreach (some calls, some SMS, some email, some calendar) and you'd rather pay Twilio's actual rates than a platform markup, this is the alternative.

(If you're also considering HubSpot, Pipedrive, or Zoho Bigin — I've written about each. And if you're not sure whether Groundbase actually fits your situation, here's who it's for and isn't.)
