The Small Business CRM for Teams That Win Clients in Conversations

A small business needs a CRM once more than one person talks to the same clients, or once a follow-up has slipped because it lived in someone's inbox. Customermates is an open-source, AI-native CRM built in Germany for client-facing teams of roughly 1 to 50 people: consultancies, agencies, B2B service firms and founder-led companies that win work through email, LinkedIn and WhatsApp. It is a poor fit if you sell by phone, run email campaigns or need single sign-on today; the limits section names what to look at instead. Customermates publishes this page.

What changes as a small business grows

A team of 3 runs into different problems than a team of 40, and needs a different plan.

Above that size, or when IT requires single sign-on and field-level permissions, an enterprise suite is the honest recommendation.

A small-business setup in Customermates

Customermates starts with five lists, and you can add your own. This mapping of the five fits a B2B service business; field names are examples you create yourself.

A deal can link several contacts, which covers B2B work where a buyer, a decision maker and a technical reviewer all have a say. The Role in deal field on each contact tells a colleague who to call about what.

Stages and a pipeline number you can explain

A new workspace has a Stage field on deals with a win probability per option: Prospecting 10%, Qualification 20%, Demo 40%, Proposal 60%, Negotiation 80%, Won 100% and Lost 0%. Rename them to match how you sell, for example Discovery instead of Demo. A deal's value is the sum of its line items, each a service times quantity, and the pipeline shows totals and weighted totals per stage. The weighted number is your value times your own probabilities, so you can explain it to a partner or a bank. It is not a prediction.

Saved views for the weekly review

1. My open deals: deals where you are an assigned user, as a board grouped by Stage.
2. Stalled: deals in Proposal or Negotiation whose Updated at is older than 14 days.
3. Next steps: open deals sorted by Next step, earliest first.
4. New from referrals: contacts with Source Referral, created in the last 30 days.

Saved views are personal, so each colleague sets the same filters and saves their own view.

People, roles and the audit log

Deals have assigned users rather than a single owner, so two people can share an account. A custom role can set Read access to Assigned on contacts, organizations and deals, which lets a junior consultant or a freelancer see only their own clients. Permissions are per resource and action. The audit log records changes to records and workspace settings for roles that have the audit permission, on every plan and in the self-hosted edition.

Conversations on the record (Pro and above)

In Customermates Cloud, the unified inbox brings Gmail, Outlook or IMAP email together with LinkedIn, WhatsApp, Instagram and Telegram, and you reply on the original channel. A conversation shows on a contact's timeline when a participant matches that contact's email address, phone number or profile. Threads from a personal account stay private until their owner shares them. On Business, a whole connected account can be shared, so a team mailbox is visible to everyone who answers it.

Marketing handoff without a marketing platform

Customermates has no campaign object, forms, tracking or attribution model. What it can do is keep the source of each contact in a field like Source, written by hand, by import or by your website through the REST API. Your analytics or email tool stays in charge of clicks and campaigns. The CRM then answers the questions sales needs: where did this client come from, is there an open deal, and who is assigned.

A Monday routine with Mate (Customermates Cloud)

Mate is the assistant in Customermates Cloud and uses hosted AI credits included per active user on every cloud plan; reading inbox conversations needs Pro or higher. A routine runs a saved instruction on a schedule or when a record changes. Set it to repeat every week on Monday morning with an instruction like this:

List deals in Proposal or Negotiation that have not been updated for 10 days.
For each, read the latest inbox conversation with its contacts. If my last
message has no answer, save a short follow-up as a draft reply in that
conversation. Do not send anything. End with a table: deal, stage, assigned
users, days since the last update, draft saved yes or no.

Prefer your own AI? Claude, ChatGPT and other clients connect through MCP on every plan and on self-hosted installations, and your AI provider bills the model use.

What Customermates does not do for small businesses

• No calling or SMS, no email sequences and no mass email.
• No web forms, lead scoring or data enrichment.
• No quotes, invoices or time tracking. Pass won deals to your accounting tool through webhooks or the API.
• Tasks have no due dates or reminders. Use a date field and a saved view.
• No native Slack app, no mobile app and no SSO.
• Self-hosting gives you the open-source CRM with REST, webhooks and MCP, but no inbox and no Mate.

If one of these decides your purchase, look at a tool built for it. Customermates publishes this overview; vendor details were checked on 8 October 2026 on each vendor's own website.

What it costs

Prices are per user per month, billed monthly. Every plan includes REST, webhooks and MCP.

Each cloud plan adds monthly hosted AI credits per active user for Mate; the amounts are on the pricing page. Starter includes 1 routine per user and Pro 5. A self-hosted installation costs no licence fee. The CRM cost guide shows how to compare quotes that bill annually.

Moving in from a spreadsheet or another CRM

1. Save each list as an Excel workbook

   The import reads .xlsx files only. Save any other export as .xlsx first.

2. Import organizations, then contacts

   On each list, open More actions and choose Add from file. A company-name column on contacts links them to their organization.

3. Import open deals

   Include Stage and Next step, then add line items so each deal gets a value. Check for duplicates first: an import cannot be undone.

4. Connect the inbox and invite the team

   On Pro or higher, each person connects their accounts under Settings › Channels. Create roles before you invite people.

Records export the same way, one record type at a time, and the REST API reads every record your role can see. There is no whole-account export.

Data protection

In Customermates Cloud, the primary production database is configured in the AWS Frankfurt region. Hosting and other subprocessors, US providers among them, are on the subprocessors page, and a data processing agreement is available. Customermates holds no certification such as ISO 27001 or SOC 2. If you need full control over where data lives, self-host the open-source core.
