What should we spend on management fees?

Fees are usually a percentage of spend, a flat retainer, or a hybrid. What matters is whether the fee buys enough senior time and creative output to move the numbers.

Should one agency run every channel?

A single agency simplifies coordination and measurement. Specialists can outperform on individual channels. Larger budgets often justify splitting; smaller ones rarely do.

How long is a fair trial period?

Long enough to gather statistically useful data — typically one to two quarters for considered B2B purchases, less for high-volume ecommerce.
