Frequently asked questions

How does 24-48h payment work?

As soon as your invoice is issued and your timesheet is signed and validated by the client, we pay you within 24 to 48 hours — without waiting for the client's payment. It's included in the Fast offer.

What is the between-assignment advance?

Between two assignments, we can pay you a cash advance, recovered progressively on your next assignment. The gap between assignments shouldn't be a period of financial stress.

I'm a freelancer with my own company in France — does it work?

Yes. In France, we work through B2B subcontracting with your company. In Luxembourg, we offer payroll services (portage salarial). One relationship, two countries.

What does "transparent margin" mean?

On placements, our margin is displayed: you know the client rate and your remuneration. No hidden spread.

Can I switch offers along the way?

Yes, the offers are designed as stages on the same rail: you move from Essential to Fast (or back) depending on your needs at the time.
