But every agency says they're performance.
Performance is a fee structure, not a tagline. Most performance agencies still bill a retainer of $5k–$15k a month whether revenue is up 40% or down 20%. That's a subscription with a results-flavoured wrapper. Rootline charges zero retainer, zero management fee, zero setup fee on ad management. The only money that moves between us is tied to what the campaigns actually produce: a percentage of campaign-attributed revenue for Shopify brands, a fee per qualified appointment for service businesses. If the work doesn't earn, we don't invoice. Add-on services like social management and content direction are sold separately with their own monthly pricing. That's where retainers exist, scoped to the work.
