Pricing at a glance

GoNimbly

Model
Custom quote with flexible engagement models: both ongoing RevOps services (effectively retainer-style/embedded team support) and project-based engagements. Go Nimbly also uses a defined discovery/planning step called "Phase 0" ahead of complex projects.
Typical range
$50,000-$199,999 per project

Inbox Attack

Model
Hybrid fixed-fee/project pricing plus monthly retainer options, with a la carte service pricing and paid 1:1 sessions. Specifically: one-off system builds and audits sold at flat fees, channel/package builds sold as fixed-price packages, and an ongoing 3-month managed engagement sold as a monthly retainer. Not performance-based; the site explicitly says they turn down commission-based projects and appointment-setting work.
Typical range
$145-$2,650 per fixed-price service or session
