The Open-Source CRM for Solopreneurs That Runs Your Business With You

Why solopreneurs need a CRM

When you run a one-person business, you are the sales team, the account manager, the support desk, and the marketing department, all at once. Every inquiry, every follow-up, every proposal lands on your desk. A CRM for solopreneurs keeps warm leads from going cold and revenue from slipping through the cracks.

A solopreneur CRM replaces scattered tools with one system that tracks every contact, every conversation, and every opportunity.

Common challenges a one-person CRM solves:

• No single source of truth: Contacts live in your email, notes in your phone, deal info in a spreadsheet. Context is always missing when you need it most.
• Forgotten follow-ups: A warm lead messaged you two weeks ago and you never replied. Without a list of open follow-ups, these opportunities disappear silently.
• Hours lost to admin: Copying data between tools, updating spreadsheets, writing the same emails: time you should spend on billable work.
• No pipeline visibility: How much revenue is in play? Which deals are about to close? Without a visual pipeline, you are guessing.
• Scaling feels impossible: Moving from 20 contacts to 200 means your informal methods collapse. A CRM for solo business owners gives you the structure to grow without hiring.

If you are a freelancer, consultant, coach, or any type of solopreneur, a lightweight CRM is the difference between reactive chaos and a repeatable sales process.

How Customermates helps solopreneurs

Customermates is an open-source CRM built for people who want powerful tools without the complexity and cost of systems designed for 500-person sales teams. Setup takes minutes, not weeks.

Everything in one record

Every contact has a complete profile: notes, tasks, deals, custom data, and on Pro the linked email and chat conversations. When a prospect reaches out, you have full context in seconds through the contact management system. No more opening five tabs to piece together a conversation history.

Visual deal pipeline for one person

Track every opportunity from first contact to closed deal on a drag-and-drop Kanban board. See exactly where each deal stands: New Lead, Contacted, Proposal Sent, Negotiation, Won, Lost. When you are the only person managing the pipeline, this visual overview is the fastest way to know what needs attention today.

Follow-ups that do not depend on your memory

This is where a solopreneur CRM earns its keep. Customermates has no built-in reminders or rules engine, but it gives you three dependable ways to keep follow-ups visible:

• Saved views: a view of deals in "Proposal Sent" sorted by last update, or of contacts sorted by a custom "Next check-in" date field, is your daily follow-up list.
• Routines on Customermates Cloud: the Mate assistant runs a saved prompt on a schedule or on a CRM event, for example every Monday listing clients you have not contacted in 30 days and drafting a check-in for each one for your review. Starter includes 1 routine per user.
• External automation: webhooks and the REST API feed a separately operated n8n or another scheduler that creates tasks or sends emails from your own accounts.

No more sticky notes, no more "I meant to reply." This is how solopreneurs nurture clients without a team.

AI agents that handle the busywork

Connect Claude, ChatGPT, or another AI client through the MCP server (49 tools) and let it do the data entry. Agents draft follow-up emails, create contacts from a message, move deals between stages, and summarize your interaction history with a client. You choose and pay for the AI client. On Customermates Cloud, the Mate assistant works inside the app with monthly AI credits included in every plan, and asks for confirmation before it deletes anything or sends a message.

Client nurturing without a team

As a solopreneur, your existing clients are your most valuable asset. Repeat business and referrals drive growth, but staying in touch is hard when you are buried in project work. Customermates keeps the relationship work visible:

• A custom date field for the next check-in, and a saved view sorted by it
• A routine on Customermates Cloud that drafts check-in messages for past clients
• A "Referred by" link or single-select field to see which clients bring you new business
• Anniversary and milestone dates as custom fields, with messages sent by an external tool you operate if you want them automated

You get the consistency of a team without actually having one.

Simple setup in minutes

No implementation consultants and no 30-page configuration guides. Sign up, then add contacts manually, import them from an Excel workbook (XLSX), or create them through the REST API or an AI client over MCP.

Key features for solopreneurs

Deal pipeline with Kanban view

See every deal at a glance on a visual pipeline. Drag and drop to update status. Know instantly what to work on next. To separate service lines (consulting and retainer work, for example), add a single-select field for the service line and group or filter the board by it.

Complete contact records

Every person and company gets a full profile with activity history, notes, tasks, and deal information through contact management. You never walk into a conversation unprepared. Search across all contacts to find that one client who mentioned a referral three months ago.

Workflow automation through webhooks and n8n

Automate repetitive work with the tools you already use. Webhooks report record changes, the REST API writes back, and a separately operated n8n with the Customermates community node connects to hundreds of other apps: your calendar, email, invoicing tool, project management system, and more. n8n is not part of any Customermates plan.

AI agents that operate the CRM

Connect Claude, ChatGPT, or another AI client through the MCP server and let it draft emails, generate summaries, and keep deal stages and notes up to date. MCP access is included in every plan; the AI client is yours to choose and pay for.

Custom fields and views

Adapt the CRM to your business, not the other way around. Add the custom fields your solo business model requires, such as project type, budget range, referral source, or contract end date. Create filtered views to segment contacts by status, industry, or engagement level.

Native unified inbox

On Pro, connect email (Gmail, Outlook, or IMAP) plus WhatsApp and Instagram through the unified inbox, link each client conversation to the right contact, and answer from inside the CRM. No more digging through your inbox to find what you said to whom three weeks ago, and Mate can draft replies that you confirm before they are sent.

Full API access

Connect Customermates to your website, invoicing tool, or any other system through the REST API. The API is included in every plan, no premium tier required. Build custom integrations that fit your exact workflow.

Solopreneur CRM vs. spreadsheets vs. enterprise tools

Many solopreneurs start with a spreadsheet. It works at first, but breaks down as your business grows:

Enterprise CRMs like Salesforce and HubSpot are powerful but designed for large teams. They require configuration, training, and ongoing admin. That overhead rarely pays off for a one-person setup. Customermates gives you the features you need at a price and complexity level that fits a solo operation.

How solopreneurs actually use Customermates

The consultant workflow

You meet a prospect at a networking event and add them to Customermates from your phone browser. You send a proposal and move the deal to "Proposal Sent". Your Monday routine on Customermates Cloud lists proposals without an answer after a week and drafts a follow-up for each. The client signs, and you record the next check-in date on the contact. Three months later, that contact shows up in your saved check-in view so you can ask about additional projects. Every step is tracked and nothing depends on memory.

The online service provider workflow

Leads come in through your website contact form. A separately operated n8n workflow or your own script sends them to Customermates through the API and creates a task to respond. You qualify them using custom fields (budget, timeline, scope). Qualified leads move through your pipeline. After project delivery, your own automation or a routine drafts the request for a testimonial or referral. Your CRM becomes a client acquisition system that runs next to your service delivery.

The coach or creator workflow

You manage a mix of one-on-one clients, group programs, and digital products. Custom fields track which program each contact is in, their renewal date, and engagement level. Your own n8n instance or another external service can handle onboarding emails, session reminders, and re-enrollment campaigns through the API. In Customermates, configured stage probabilities produce deterministic weighted deal values and pipeline totals across service lines; the product does not predict future revenue.

Pricing that makes sense for solopreneurs

For a lean, one-person operation, what matters is that the cheapest plan already has what you need. In Customermates, the API, webhooks and MCP are part of every plan:

• Starter (€12 per user per month): pipeline, custom fields, dashboards, REST API, webhooks, MCP, and the Mate assistant with monthly AI credits
• Pro (€29 per user per month): adds the unified inbox for client email, WhatsApp, and Instagram
• Self-hostable: run the open-source core on your own servers with no licence cost; the inbox and Mate are cloud-only
• Data protection: the cloud database runs in the AWS Frankfurt region, a DPA is available, and subprocessors are disclosed

For a solopreneur, that is €12/month on Starter, or €29/month on Pro if you want client conversations inside the CRM, billed monthly. See our full pricing details.

For comparison, Pipedrive lists €24 to €99 per seat per month on monthly billing, or €14 to €79 on annual billing (September 2026). HubSpot lists Sales Hub Starter at €20 per seat per month (September 2026), with a free plan for up to 2 users.

Integrations for solo workflows

Customermates connects to the tools solopreneurs already use through the REST API, webhooks, and a separately operated n8n with the Customermates community node:

• Email: On Pro, connect Gmail, Outlook, or IMAP to the unified inbox so client conversations sit next to the contact
• Calendar: On Pro, see your calendar read-only; booking meetings stays in your calendar or booking tool
• Invoicing: Link to Stripe, PayPal, or your accounting tool through n8n or the API; Customermates does not create invoices
• Forms: Send leads from Typeform, your website, or landing pages into Customermates through n8n or the API
• Communication: WhatsApp, Instagram, and Telegram live in the Pro inbox; Slack or SMS messages go through n8n and a provider you operate
• Productivity: Integrate with Notion, Trello, or Asana for task management through n8n or the API

n8n offers hundreds of app connectors; you run n8n yourself or on n8n's own cloud.

Data protection and data ownership

As a solopreneur handling client data, you are responsible for GDPR compliance, especially if you work with European clients. Customermates gives you what you need to assess it:

• Cloud data location: the application database runs in the AWS Frankfurt region; hosting and other subprocessors, including US providers, are listed on the subprocessors page
• DPA: a data processing agreement under Art. 28 GDPR is available
• Open source: full transparency; audit the code yourself
• Self-hostable: run it on your own infrastructure and choose where the data lives
• Open data access: export contacts, organizations, or deals as an Excel workbook (XLSX), one record type at a time, or read records through REST
• Consent fields: record consent status and date in custom fields on the contact

Customermates holds no compliance certification. Read more about CRM best practices to get the most from your setup.
