The steps, in order, with nothing implied that Koovira does not do.
Four or five steps, and what each one actually does.
Answered plainly, including the things Koovira does not do.
You can enter the whole requirement without an account. A Koovira account is needed at the point of submitting it, so the requirement has an owner, a booking code and a place for carrier responses to arrive.
No. Koovira does not publish a rate card. You post the requirement and transport partners respond to it; you compare what comes back.
Transport partners on Koovira see the route and cargo of open requirements so they can respond. Your contact details follow the platform access rules.
Use "Join as merchant". Drivers have their own onboarding and are not registered as merchants.
