In short

What is Zircon CRM?

Zircon CRM is a browser-based CRM system and business management tool for agencies, IT service providers, consultancies and other B2B service businesses. It runs the whole client lifecycle in one place: lead, proposal, contract, project, tracked time, invoice, online payment, support and renewal. Hungarian companies issue official invoices through its Számlázz.hu integration.

We run on it

We work on it every day.

Zircon runs its own company on Zircon CRM. What we show you in the demo is what we use ourselves, and we don't recommend anything we wouldn't use.

Since 2015

That is how long we have been building and running systems: webshops, automations and custom business software.

17+ countries

The webshops and automations we have built serve customers in that many countries.

Hosting in three countries

We run our systems in Hungary, Germany or Finland, or on the client's own servers.

Sound familiar?

Five tools, one client, no full picture.

Most service businesses run on a patchwork. Every hand-over between two tools costs time, and something gets lost on the way.

  1. 01

    Sales can't see the invoices

    The CRM has the won deal, the invoicing service has the invoice. Whether the two match is something somebody checks by hand.

  2. 02

    The project doesn't know what the proposal promised

    The project tool gets retyped from the proposal, and the hours worked pile up in a third place.

  3. 03

    Renewals live in a spreadsheet

    Which domain expires next month, and what is the margin on that hosting plan? A spreadsheet knows, if someone kept it up to date.

  4. 04

    Support sits in a shared inbox

    The question arrives, but nobody sees the client's contract or open invoices next to it.

One system, end to end

From the first enquiry to the paid invoice.

Every step carries its data into the next one, so nothing gets typed twice.

  1. 01

    Lead

    Arrives from a website form or a monitored mailbox and moves through a Kanban pipeline.

  2. 02

    Proposal

    Built from a template, sent even to a lead, and accepted by the client online.

  3. 03

    Contract

    Signed online: the typed name, the drawn signature, a timestamp and the IP address go onto the document.

  4. 04

    Project

    Milestones, tasks and Gantt charts, and you decide per project what the client can see.

  5. 05

    Time

    Timers on tasks with rounding rules. Tracked hours can be invoiced from the project.

  6. 06

    Invoice

    Several taxes per line, discounts, currencies, recurring invoices and reminders for overdue payments.

  7. 07

    Payment

    Ten online payment gateways, including Stripe, PayPal and Mollie, with partial payments.

  8. 08

    Renewal

    Hosting, domains and SSL per client, with renewal dates, margin and renewal invoices.

Modules

Every module, by area.

The 23 bundled modules can be switched on or off without losing data, so you only use what you need. Every capability has its own page.

Administration

What is different

Six things Zircon CRM does differently.

  1. 01

    AI assistants, with rules

    Through the built-in MCP server, Claude, Cursor or VS Code work inside the system with the staff member's own permissions. Every call is logged.

  2. 02

    No retyping, end to end

    A lead becomes a client, an estimate becomes an invoice, project time becomes invoice lines. Every conversion carries the data forward.

  3. 03

    Built for Hungarian invoicing

    The Számlázz.hu integration issues the official invoice reported to the Hungarian tax authority and brings back the official number and PDF.

  4. 04

    Tools service businesses need

    Hosting and domain renewals with margins and a 12-month forecast, a Social Manager for your own channels, and a media library with permanent links.

  5. 05

    Three languages, all the way through

    The whole system is complete in English, German and Hungarian. Every staff member, client and lead gets the interface, e-mails and PDFs in their own language.

  6. 06

    On your servers, if you like

    A container-ready web application: it can run on your own server or private cloud, or on our EU servers.

AI

Your AI assistant works inside the CRM, by your rules.

The MCP server built into Zircon CRM is a standard gateway: the AI assistants your team already uses read and write through it. They suggest and carry out what you ask; the decision stays with you.

86 tools in 12 areas

Clients, leads, projects, tasks, tickets, knowledge base, calendar, to-dos, media library and Social Manager. Invoices and estimates are read-only for the assistant.

With the staff member's permissions

Sign in with the Zircon CRM account (OAuth 2.1) or a personal token. The assistant sees and does what the signed-in staff member may.

Logged and limited

Every call is logged. Administrators can switch areas off, allow 120 calls per minute per token by default, and revoke any connection.

Supported clients

Claude (web, desktop and mobile), Claude Code, Cursor, VS Code (Copilot agent mode), Codex CLI, Gemini CLI, Windsurf and n8n. The system must be reachable over HTTPS.

Customer portal

Your clients handle their business where you work.

Every contact gets their own login to the customer portal, in their own language. You decide per contact and per project what they can see.

Invoices and payment

Clients view their invoices and pay them online. Hungarian clients also see the official number and PDF that came back from Számlázz.hu.

Proposals and contracts

Clients accept estimates and proposals and sign contracts online.

Projects and tickets

Clients follow their projects, open tickets and read the public knowledge base.

Services and details

Clients see their hosting and domain services, manage their company details and colleagues, and exercise their GDPR rights.

Hungarian invoicing

Official Hungarian invoices through Számlázz.hu.

For companies invoicing in Hungary, the built-in Számlázz.hu integration issues the official invoice reported to the tax authority (NAV); the Zircon CRM invoice itself is not reported. The official number and PDF come back to Zircon CRM and the customer portal.

Issue or import

Issue an invoice in Számlázz.hu in one click, or bring invoices issued in Számlázz.hu into Zircon CRM.

Payments and reversals

Payments and reversals registered in Számlázz.hu are mirrored in Zircon CRM. Not the other way round: payments recorded in Zircon CRM are not sent to Számlázz.hu.

Buyers by tax number

Buyers are matched on the 8-digit Hungarian tax base number, and only when the match is unambiguous.

Worth knowing

You need a Számlázz.hu account and a Számla Agent key. There is no test mode, the invoice number prefix is updated once a year, and automatically created invoices have to be issued separately.

Who it is for

A CRM system for businesses that sell time and expertise.

Agencies

Many client projects at once, fixed-price and hourly work side by side, constant content production.

IT service providers and hosting resellers

Project work plus hosting, domains, SSL and servers, monthly fees and a support desk.

Consultancies

Proposals and contracts at the centre, billing by the hour or by milestone.

Support-led businesses

Lots of questions by e-mail, web and phone, where response time matters.

AI-forward teams

Claude, Cursor or Copilot are already in use and should work with real business data, safely.

Owners and managers

A personal dashboard, reports for the accountant, and access controlled per role.

Data and access

Where your data lives, and who sees what.

Your server or EU hosting

It can run on your own servers or private cloud. If we run it: in Hungary, Germany or Finland.

Daily backups

If we run the system, we back it up daily and keep the backups for 30 days by default.

Own or all

Per role and per area, you decide whether someone sees only their own records or everything.

Sign-in

Optional two-factor login for staff, reCAPTCHA and a log of sign-ins.

GDPR tools

Consent per purpose, data export and removal requests for clients and leads.

Activity log

The system logs who changed what. Administrators can clear the log, so it is worth covering that in your internal policy.

Getting started

How we get you going.

  1. 01

    Demo

    We look at how you work today and show you Zircon CRM on your own process.

  2. 02

    Fixed-price quote

    After the first call you get a written quote at a fixed price.

  3. 03

    Set-up

    Roles, templates, invoicing, and your existing clients, leads, items and expenses loaded from CSV.

  4. 04

    Operations

    If it runs on our servers, we run it. Support is on weekdays, 9–17.

Honestly

Not for everyone.

  • If your business lives on physical stock, a warehouse or production: Zircon CRM has no inventory module.

  • If you want to resell it under your own brand today: we haven't yet decided what can be fully rebranded.

  • If you are a one-person business that only needs to send invoices: Számlázz.hu on its own is enough.

Price

A fixed price, after the first call.

Fixed price, quoted after the first call. There is no public price list: the price depends on the modules you need, where the system runs and how much set-up it takes. You get a licence to use it; the code stays with Zircon.

Before you write

Fair questions. Straight answers.

  1. 01

    How is Zircon CRM different from a plain CRM system?

    A plain CRM system stops at sales. Zircon CRM carries the client on in the same system to the project, tracked time, invoice, payment, support and renewals, so nothing has to be copied between tools.

  2. 02

    Can Zircon CRM issue official invoices in Hungary?

    Yes, through the built-in Számlázz.hu integration. The Zircon CRM invoice itself is not reported to the tax authority: Számlázz.hu issues the official invoice, and the official number and PDF come back. You need a Számlázz.hu account and a Számla Agent key.

  3. 03

    Where does Zircon CRM store our data?

    Where you want it. Zircon CRM can run on your own servers or private cloud, or on our servers in Hungary, Germany or Finland.

  4. 04

    Which AI assistants work with Zircon CRM?

    Through the built-in MCP server: Claude (web, desktop, mobile), Claude Code, Cursor, VS Code in Copilot agent mode, Codex CLI, Gemini CLI, Windsurf and n8n. Each works with the signed-in staff member's permissions, and every call is logged.

  5. 05

    Do we need to install anything to use Zircon CRM?

    No. Zircon CRM runs in the browser; staff and clients don't install anything on their computers.

  6. 06

    Which languages does Zircon CRM come in?

    The whole system, every in-house module included, is complete in English, German and Hungarian. The core is available in 25 further interface languages. Every staff member, client and lead has their own language for the interface, e-mails and PDFs.

  7. 07

    What is Zircon CRM built on?

    On an established, widely used CRM core that we have extended with 14 in-house modules: the Számlázz.hu integration, hosting and domain renewals, the Social Manager, the media library, the MCP server and more.

  8. 08

    Does Zircon CRM handle stock or a warehouse?

    No. Zircon CRM is built for businesses that sell time, expertise and recurring services. If your business runs on physical stock, we will recommend a different system.

  9. 09

    Can we bring our existing data into Zircon CRM?

    Yes, from CSV files. Clients and contacts, leads, items and expenses can be imported, and a dry run shows the result before anything is saved.

  10. 10

    How much does Zircon CRM cost?

    There is no public price list. After the first call you get a fixed-price quote that fits the modules you need, where it runs and the set-up.
