Budget shifting: portfolios shift budget to the accounts returning the most
Tell Pace what each kind of conversion is worth to you, once, and it compares your Google and Meta accounts on those conversion values, ROAS style (say 3.4x against 1.9x). Each day it shifts a little budget from the accounts returning less to the ones returning more that keep running out. The portfolio's total never changes.
Anything in a budgeted campaign group stays exactly as it is, and campaign minimums and maximums are always respected. Each account shifts by a small share of its own budget a day and stays within a shift limit you set. Switch off Included for any account you want left alone. If an account leaves the portfolio, Pace rebalances the rest straight away. Changed your mind? One click undoes the month's shifts.
Turn on Budget shifting in portfolio settings, on the Budget tab. It starts in Preview, which shows estimates only, so budgets don't change until you switch to Automatic. The Budget shifting card on the portfolio Overview shows what was shifted and why, and every shift appears in Changes on both accounts. Available on Pace One and Enterprise.
