For clients hiring on the marketplace.
On the BotPool marketplace you can buy a service package or agree a custom project. A service package is something a freelancer has already defined: fixed scope, fixed price, fixed timeline. You buy it as advertised. Good when what you need is a known quantity.
A custom project is scoped with the freelancer for your situation, usually starting with a message. Slower to agree, better when the work doesn't fit a box.
Both hold your payment in escrow (BotPool keeps it until you confirm you're satisfied), and both can be fixed-price or hourly.
