The everyday problems window fitters face

You can't hear the phone during a fitting

On site, the window half in its frame – the call goes nowhere and the prospect asks the next firm.

How Terminstimme solves itTerminstimme answers every call while you fit, and books the measuring appointment straight away.

Every job starts with measuring up

No measuring appointment, no quote – and a window replacement is quickly worth several thousand euros.

How Terminstimme solves itThe assistant books the measuring appointment immediately, while interest is fresh.

Funding and price questions cost time

Always the same questions about funding, lead times and materials – each one eats minutes on the phone.

How Terminstimme solves itTerminstimme answers standard questions directly and only then books the appointment.

How it works

Three steps to a booked appointment

1

A call comes in

Your customers call your existing number as usual. You answer whenever you can – only when no one picks up (busy, peak time, after hours) does Terminstimme step in automatically after a few seconds. Your number stays the same.

2

A natural conversation

The assistant greets the caller, understands their request and answers questions about services and opening hours – in fluent, natural language. It recognises emergencies and forwards them to you.

3

Booked & confirmed

Available slots are checked in real time, the appointment lands straight in your calendar – and your customer automatically receives an SMS confirmation.

Set up for you

Tailored to your business – without you touching any tech.

Terminstimme isn’t a self-service software subscription. No account, no login, no calendar you have to connect yourself. We set the phone assistant up completely for you – tailored to your services, your opening hours and the way you speak. You focus on your trade, we handle every technical detail.

What we take care of

  • Bespoke setup – tailored to your business
  • Connecting your calendar – we do it for you
  • Voice, greeting, services and opening hours configured to fit
  • Ongoing operation, monitoring and adjustments on request

What you never have to do

  • No account to create, no login, no password
  • No connecting or configuring a calendar yourself
  • No settings, no dashboards, no tech
  • A dedicated contact – not anonymous self-service
Live demo

Hear it for yourself.

The most convincing thing is simply to call. On our demo number, Terminstimme answers as the assistant of a fictitious example trade business – no sign-up needed.

Tip: just say „I'd like an appointment to measure up for new windows“ – the business is fictitious, no real appointments are created.

Frequently asked questions

What you should know

Can the assistant answer questions about funding?

Yes. Common questions – about funding programmes, lead times or materials – you set up once, and the assistant answers them in the call.

Does the assistant book a measuring appointment directly?

Yes. Free slots are checked in real time and the measuring appointment lands straight in your calendar – with an SMS confirmation for the customer.

Does my existing phone number stay the same?

Yes. Terminstimme is integrated via overflow on your existing number – your customers keep dialling the same number. On request, we'll also set up a dedicated appointment number.

Can I try Terminstimme without risk?

Yes – there is no setup fee and no minimum term. You see from real numbers in the monthly report how many calls would otherwise have been lost, and can cancel at the end of any month.
