Jonas: The All-in-One CRM & Planning App for Dutch
Entrepreneurs
Are you tired of juggling Excel files, WhatsApp messages,
loose notes, and too many different apps to manage your clients and projects? Meet Jonas, the ultimate all-in-one business planner
and CRM app, specially developed for independent Dutch
service providers. From painters and plumbers to contractors and freelancers,
Jonas is made for you.
Jonas is designed for freelancers and small teams who want an overview without
complicated software. With Jonas, you centralize your client information, schedule
appointments, and manage your project files in a simple, clear
and fully Dutch-language interface.

Why Jonas?
Because you don't need a plethora of features. You need one reliable
tool that does exactly what your business needs—nothing more, nothing less.

Key Features
Client Management, Simple and Clear
Store all your client information, contact details, and project notes in one
central environment. No more hassle with separate apps or sticky notes. With
Jonas, you have instant access to files, photos, and updates, whether you're
in the office or on the road.

Smart Appointment Scheduling
Quickly schedule new jobs, receive automatic reminders, and reduce
no-shows. Jonas syncs your calendar in real time across all your
devices, so your schedule is always up-to-date.

Dutch-Compliant Invoicing
Create invoices in seconds that are fully compliant with
Dutch tax regulations. Add your own branding with logo and colors, so your
invoices look professional and reliable.

All Project Files in One Place
Upload and manage before-and-after photos, quotes, work orders, and PDFs. Everything
is linked to your project and client, so you never have to search
through WhatsApp folders or Dropbox again.

Real-time synchronization across all your devices
Whether you're at a client's home or working on your laptop in the evening: Jonas ensures
that your files, appointments, and notes are instantly available everywhere. What you
see, your team sees too.

Built for the Dutch market
No more American templates or English menus. Jonas is
developed by and for Dutch entrepreneurs, with local language support, euros,
SEPA invoices, and Dutch-speaking customer service.
