BlogGuides and tipsCustomer storiesHow teams use ZeegResearchNumbers from real bookingsChangelogNew in ZeegZeeg answers client calls around the clock and books consultations straight into your calendar. GDPR compliant, made in Germany.
Call and have it book an appointment for you, just as your clients would.
An AI phone agent answers your tax firm's calls when nobody can pick up. Zeeg's AI phone agent speaks naturally, records what the caller needs and books consultations straight into your calendar, around the clock and in 23 languages.
The AI phone agent answers every call at once, even when you are in a consultation or your team is working on the annual accounts. It records the matter and answers questions from your documents, for example about opening hours or the receipts needed for the tax return. Whatever it cannot settle, it records with a callback number.
During the call the agent checks the free times in your calendar and books the appointment at once, whether a first meeting, an annual review or advice on setting up a GmbH. The client gets a confirmation by email and can later reschedule or cancel the appointment by phone too.
No keypad menu, no hold queue. The agent speaks naturally, asks follow-up questions and addresses your clients formally. At the start it says that it is an AI assistant, as the EU AI Act requires. After every call your team gets a summary, and the full transcript is in the dashboard.
Upload a list of the clients whose documents for the tax return are still missing. The agent calls them at set times, reminds them about the receipts and books an appointment straight away if they want. If it only reaches voicemail, it leaves a message.
Decide which matter belongs in which calendar and which calls are put straight through. The agent recognises during the call whether it is about the tax return, bookkeeping or payroll, books with the person responsible and puts urgent questions through at once.
No code, no prior knowledge. Within minutes your agent answers its first calls.
Say in your own words how your firm works, which matters the agent settles itself and which it puts through. Zeeg builds the agent from that.
Talk to your agent right in the dashboard and adjust what it says before a client calls.
Forward your firm's number or take a new local number. From then on the agent answers every call.

Verified“I’ve now set up five clients with Zeeg, including law firms, media agencies and a skin clinic, and for all of them the AI voice agent matters most. It answers calls on holidays and after hours, answers callers’ questions and books the appointment straight into the business’s Google or Outlook calendar.”
Verified“Every morning, the first thing I check in Zeeg is what our AI voice agent has arranged since yesterday. It asks callers the first questions and then books the right appointment. […] The agent also calls out on its own: contacts we want to follow up with get a call with their own greeting at a set time.”
Verified“The practical, simple setup of the AI voice agent deserves a special mention. The AI voice agent also sounds authentic and helps us take customer enquiries and bookings 24/7.”
Verified“Zeeg lets us tailor scheduling to every one of our use cases. We mainly use round robin and group events with specific presets that are easy to set up.”
Verified“We used to use Calendly and have now switched to Zeeg.me completely, and honestly, I’m thrilled!”
Verified“I add the link to every email to recruiters, and they pick a free time themselves. Thanks to the two-way sync with my Google Calendar, only times when I’m not in a lecture or another call show up, so I haven’t had a single double booking.”
Verified“Round robin events and adding the link to our email signature and website are super easy. The prices are more than fair […]”
Verified“Especially when handling client data, it matters who stores the data, where and how. […] Zeeg is a very good German alternative here: easy to use, with every feature you need.”
Verified“Zeeg makes scheduling with my clients easier every day. I send my clients the link, and they can easily book a time that suits them.”
Calendars, video conferencing, CRMs, payments, analytics and single sign-on: Zeeg connects to the tools your team already works with.
Monthly minute packages, separate from your scheduling plan. The bigger the package, the lower the price per minute. Custom packages on request.
It takes enquiries from new clients, books first meetings and annual reviews, reschedules or cancels existing appointments and answers questions from your documents, for example about opening hours or the receipts needed for the tax return. It puts urgent questions through to the right number and records everything else with a callback number.
The AI phone agent runs on its own minute packs. You only pay for AI minutes, from as low as €0.11 per minute, with packs from €49 per month for 250 minutes with annual billing.
Yes. The default greeting says at the start of every call that the caller is talking to an AI assistant, as the EU AI Act has required since August 2026. You can change the wording of the greeting, but you keep the reference to AI.
Under § 62a of the German Tax Advisers Act (StBerG), you oblige service providers who process client data to confidentiality in writing. On request, Zeeg signs your firm's confidentiality undertaking and signs a data processing agreement under Art. 28 GDPR with you.
Yes. Zeeg's agent is GDPR and EU AI Act compliant. Conversation data is stored in the EU, and calls run through the Irish region of our telephony provider. Zeeg stores appointments and contacts encrypted on servers in Europe. If you switch off transcript storage, the voice service stores nothing from the call.
Yes. You forward your number to the agent or connect it via SIP trunk. Or you take a new local number directly in Zeeg.
No. Zeeg handles calls and appointment booking, and your practice software stays as it is. Zeeg has no direct DATEV connection: client files, deadlines and tax returns stay in DATEV.
Zeeg comes with its own appointment booking: clients book online on the same scheduling pages the AI phone agent books into on the phone, and round robin and routing forms spread both across the team. Fonio and smao book into connected calendars or booking tools. Fonio speaks more languages, over 60 instead of 23, and smao charges no base fee, at €0.35 per minute. As of October 2026.
