Is Offrendo really free for me?

Yes. As a client you never pay anything – neither for the request nor for the quotes. Providers pay a small fee to get in touch with you.

How many providers will contact me?

No more than 3 providers receive your contact details. That gives you a real choice, but no flood of calls.

Do I have to accept a quote?

No. Your request is 100% without obligation. You decide freely whether and with whom you want to work.

How quickly will I receive quotes?

Suitable providers are notified as soon as you submit. Whether and when you receive quotes depends on the region, the service and provider availability. Up to three providers can take on your request.

How does Offrendo check providers?

When providers register, we check their company details, contact details and area of operation for plausibility. This is not a professional certification and not a guarantee of a company's quality; we block providers who receive negative feedback.
