Built around the way you actually work.
Same app, every device.
Open it in any browser. Or grab the desktop installer if you want a dedicated window. Or the Android app for when you're mobile. Same login. Same data. Real-time sync — start a text on your phone, finish it on your laptop.
A real CRM. Not a Rolodex.
Place calls. Send and receive SMS. Manage your email inbox. Track deals through a pipeline. Schedule tasks, events, and appointments. Everything tied back to the contact — no copy-pasting between four tools.
Open it. Use it.
No admin. No multi-day onboarding. No per-seat pricing. Sign up, walk through five steps of setup, and you're running your business inside Groundbase before lunch.
Everything a CRM needs.
Nothing it doesn't.
Open the tab. See everything.
Today's tasks, your open pipeline, what's overdue, what hit your inbox this week — one screen, no clicks. Built so you can answer 'where do I stand?' in five seconds, not five tabs.
The whole relationship on one page.
Every text, email, call, deal, note, and task about a contact lives on their profile. Custom fields you actually use. Tags you define. A timeline that reads like a conversation, not a spreadsheet.
Pipeline you can read at a glance.
Drag deals between stages. See total value per stage. Tag the hot ones. The board layout fits the way you actually think about a pipeline — not a sales-team SaaS dashboard with twelve required fields per row.
Text from your real number.
Bring your own number — buy a fresh one in two clicks or port your existing one. Bulk-send, schedule, attach to a contact, drop into a thread. Replies land back in the same conversation. Bill at $0.025/segment against a top-up balance — no surprise SMS bills.
Calls. Voicemail. Transcripts.
Place outbound calls from any device. Inbound rings on whatever you have open. Voicemails come with a transcript so you never play one twice. Optional call recording with full-text transcription via Whisper for the conversations worth keeping.
Your inbox, tied to your contacts.
Connect Gmail, Outlook, or any IMAP account. Every message gets attached to the right contact automatically. Send-as aliases for working under different brands. The inbox you already use, with a CRM wrapped around it.
Tasks, events, appointments. Same calendar.
Color-coded by type. Linked to the contact, deal, or company they're about. Recurrence for the weekly check-ins. Overdue lives at the top so it stops drifting. Skip the separate calendar app.
Same app. Three places to run it.
Sign in once, sync everywhere. Pick whichever fits the moment — the web app is the default, the others are extras.
Open in any browser.
No install. No download. Open app.groundbasecrm.com, sign in, you're working. The default for most users.
Windows installer.
Dedicated window. Native notifications. Works offline-tolerant — keeps reading when the wifi drops. For when the browser tab feels too crowded.

Groundbase ships a built-in Model Context Protocol server. Connect it to Claude, ChatGPT, Cursor, or any MCP-compatible AI — and your assistant can read your contacts, send texts, schedule follow-ups, and update deals on your behalf.
One connection URL, OAuth 2.1 sign-in, fine-grained revoke from Settings. Any MCP-compatible client works — we don't lock you to one vendor.
$9.99 a month.
Everything included.
Two weeks free to try it. No tier upsells. One price unlocks every feature on every device.
Try Groundbase CRM Local.
The original Groundbase — $39 one-time, runs entirely on your Windows machine, data stays in a single file you own. SMS, voice, and email all work — but you bring your own Twilio account + IMAP login, and there's no sync between devices and no mobile app. No monthly fee either.

What's the difference between the cloud version and Groundbase CRM Local?
Cloud (this page, $9.99/mo) — web app, desktop app, Android app. Sign in once, real-time sync between every device. One included phone number; SMS/voice/transcription billed against a top-up balance (we manage Twilio for you).
Local ($39 once) — Windows only, data lives in a single SQLite file on your computer. No sync between devices, no mobile app. SMS and voice work, but you bring your own Twilio account and pay Twilio directly. Email connects to any IMAP account. See the Local page →
