Client Onboarding for Fractional CFOs with Fathom
Run client onboarding on autopilot inside Fathom.
The Problem
Onboarding a new Outsourced Finance client means chasing prior-year returns, engagement letters, and a dozen document requests — and every delay pushes the first billable task further out.
What We Build in Fathom
AI drafts the engagement letter, generates a tailored document-request list for the client's Outsourced Finance profile, chases missing items across email and QuickBooks Online, and hands the partner a ready-to-work file — first billable task starts in 3 days, not 3 weeks. Purpose-built for teams running Fathom — uses the native API or agent integration so nothing leaves the system of record.
Fathom Integration Approach
Audit your Fathom configuration
We map the specific Fathom objects, custom fields, and workflows the automation needs to touch for your outsourced finance practice.
Build on the Fathom API or agent
Integration happens inside Fathom — no data leaves the system, no parallel tool for your team to learn, no license changes.
Human-in-the-loop handoff
Every automation routes exceptions back to a human in Fathom with enough context to act — AI handles the 80%, your team owns the judgment calls.
Frequently asked
Does this client onboarding automation work natively in Fathom?+
Yes — we build directly on Fathom's API or agent integration. Your data stays in Fathom, your fractional cfos keep the same login and UI, and there's no parallel system for the team to learn.
What Fathom configuration do we need before deployment?+
We work with your existing Fathom setup. During discovery we map the specific objects, custom fields, and workflows the automation touches — no rip-and-replace required for outsourced finance teams.
Can Fathom handle client onboarding on its own?+
Fathom handles configuration; AI handles judgment. Native Fathom workflows route deterministic tasks; our automation layer adds the AI judgment Fathom doesn't ship out of the box — document classification, exception triage, drafting.
Is Fathom the right tool for client onboarding for fractional cfos?+
Fathom is widely used among outsourced finance teams precisely because of its data model around client onboarding. We've deployed this workflow on Fathom for similar firms and the integration is well-trodden.
What's the typical ROI of client onboarding automation in Fathom?+
For outsourced finance firms running Fathom, automation typically pays back inside the first quarter — measured against the loaded cost of the fractional cfo hours absorbed. Higher volumes deploy faster.
