Services

Software that brings your processes together.

What lives in spreadsheets, on paper and in five separate programs today gets one system. Built around your business, not a template. We work exclusively for companies with 5 or more employees, not for private customers.

CRM systems

Customers, contacts, quotes and follow-ups in one place. Nobody has to hunt for who last spoke to whom.

  1. 1The enquiry lands in the CRM
  2. 2The quote is ready
  3. 3The invoice goes out

ERP solutions

Orders, materials, scheduling and billing in one system that works exactly the way your business does.

Automation

Repetitive tasks run on their own: reminders, documents, forwarding and data syncs.

Customer portals

Your customers see appointments, documents, quotes and invoices themselves, without having to call.

Integrations

We connect your new software with the programs you already use, so nothing is typed in twice.

Digitalising processes

Order and quote handling, booking, planning, administration and dashboards. What runs in people's heads today gets a fixed process.

Our own software · in daily use at Schwimmschule Nemo

Reference · Natarivo for swim schools

You run the swim school. Natarivo runs the office.

Courses, online booking, waiting lists, payments and an instructor portal in one system. Built inside a working swim school, not on a drawing board. That is how we build your system too.

  • Parents book in the evening from the sofa, several children in one go
  • Waiting lists move up by themselves, nobody has to ring round
  • A class is cancelled, and every family is told in one step
  • Payments, refunds and invoices at a glance
  • Instructor portal for the poolside: attendance with one tap
  • Runs in the browser, nothing to install, hosted in Germany

The product website

Take a look at Natarivo.

Everything about courses, booking, waiting lists, payments and the instructor portal is on Natarivo's own website (in German).

Go to natarivo.de

In daily use at Schwimmschule Nemo: booking and payment online.

Waiting lists in the Natarivo admin area with waiting children and the button to offer a place

The waiting list moves up by itself

When a place frees up, the next family gets the offer automatically. Nobody has to phone.
