About Sophie

Do you invoice, but never really know what's collected?

Quotes sent, invoices made, but unclear cash flow.
Result: stress and money lying dormant.

This is exactly where I come in.

I act as an administrative co-pilot to bring clarity to your cash flow and secure your collections.

In a few weeks, you'll finally know where you stand, and your payments will be truly tracked.

Some of my clients have already reduced their late payments quickly.


Specifically, I handle:

- Quotes and invoicing
- Payment tracking
- Client reminders
- Pre-accounting preparation

👉 Goal: clear cash flow, incoming payments, and freed-up time.

I also support my clients in the transition to electronic invoicing in 2026, to anticipate without stress.

One-off or regular, remote or on-site: simple, efficient, and sustainable organization.
