Frequently asked questions about selling on Otark
What does registering as a seller cost?
Nothing. Registration is free and comes without exclusivity: you decide for every tender whether you want to bid.

Which projects can I market?

How do I find out about matching tenders?
New matching demands reach you automatically by email notification and appear in your platform inbox. You bid directly and digitally, with zero cold acquisition.
How much faster do I close than in direct sales?
