If you have the "Sync estimated effort for team members"  option checked - we will sync the aggregated budget in hours for each assigned resource and set it in Harvest.

Estimated Effort for Resources in Price&Cost 

Is synced on sending the project to Harvest

In case you are syncing the estimated effort, we'll also set the project budget in Harvest to Hours per person.

Even though we set the budget as "Hours per Person", we still sync the project Total Budget (money) from Price&Cost to Project Fees in Harvest, so you can choose how you want to track your budget in Harvest.
