Consultants talk faster than they type, but they earn from typed deliverables. The voice workflow stack fixes that: Wispr Flow to dictate client emails, Slack messages, and SOPs hands-free; Fathom to capture every client call automatically; TurboScribe to batch-process recorded audio archives; and Claude to turn all that raw voice into finished work. The whole stack runs for about $50/mo.
The services this stack enables — AI productivity installs, voice workflow onboarding, audio archive projects — bill at $1,500-$5,000. Here's what each tool does, what it costs, and what to charge when you deploy it for clients.
The tools
Wispr Flow
Wispr Flow is AI voice dictation that works in any text field on Mac, Windows, iOS, and Android — Gmail, Slack, Notion, Google Docs, your CRM, anywhere you type. Context-aware formatting means it sounds like an email in Gmail and a code comment in VS Code. Pro adds Command Mode: highlight any text, say "make this shorter" or "translate to French," and it rewrites instantly. One subscription covers all your devices.
Price: free (2,000 words/week on Mac, 1,000 on iOS); Pro $15/mo or $12/mo billed annually ($144/yr); Teams $12/user/mo monthly or $10/user/mo annual. 14-day trial, no credit card. What to charge: $500-$1,500 for a voice workflow onboarding — device setup, custom dictionary with client names and industry terms, and a 30-min live training session. More often bundled into a $2,500-$5,000 AI productivity stack where voice dictation is the highest-praise line item.
Fathom
Fathom records every discovery and client call with unlimited free recordings and transcription — plus AI summaries for your first 5 calls per month on the free plan. Scope changes, commitments, and quotable pain points stop living in your memory — they're searchable, and they feed straight into proposals and Claude Projects. Premium adds unlimited AI summaries and action items; Business adds CRM sync.
Price: free forever (5 AI summaries/mo); Premium $16/user/mo annual ($20 monthly); Team $15/user/mo annual (2+ users); Business $25/user/mo annual. What to charge: $1,500 to deploy call intelligence across a client's team, plus $300-$500/mo for the weekly digest and CRM hygiene.
TurboScribe
TurboScribe handles what live notetakers can't: async batch transcription of uploaded audio and video files. Upload podcast episodes, recorded trainings, old sales calls, or customer interviews — up to 10 hours and 5 GB per file — and get back clean DOCX, PDF, or SRT output with speaker labels and timestamps in 98+ languages. The Unlimited plan at $10/mo makes high-volume archive projects viable at any client size.
Price: free (3 transcriptions/day, up to 30 min each); Unlimited $10/mo annual ($120/yr) or $20/mo monthly. What to charge: $500-$2,000 for an initial archive batch scoped by hour count, then $200-$500/mo for ongoing processing. Your cost is $10/mo regardless of volume.
Otter.ai
Otter.ai covers live meeting transcription with a free plan that includes 300 minutes/month — the right tool when a client team needs transcription in Salesforce or HubSpot from day one. Pro ($8.33/user/mo annual) adds 1,200 min/mo and the CRM integrations; Business ($19.99/user/mo annual) removes the minute cap entirely. The per-seat price makes it the budget pick for large client teams.
Price: free (300 min/mo, 1 concurrent meeting); Pro $8.33/user/mo annual; Business $19.99/user/mo annual. What to charge: $1,200 setup + $300/mo for a CRM-hygiene retainer — Otter on every rep's seat, transcripts and summaries synced to HubSpot, monthly call-notes audit.
Claude
Claude is where voice output becomes billable deliverables. Feed it Fathom summaries, TurboScribe transcripts, and Wispr Flow dictation via a client Project, and a Skills library turns raw voice into proposals, audit reports, SOPs, and weekly digests automatically. It's also the flagship service itself: the "AI operating system install" sells for $2,500-$5,000.
Price: free tier; Pro $20/mo ($17/mo annual); Team Standard $25/seat/mo. What to charge: $2,500-$5,000 for the install (Projects, Skills library, team training), then $500-$1,500/mo to maintain it.
A workflow that sells
The voice-to-deliverable pipeline — a single operator running it solo:
- Wispr Flow dictates the day. Client emails, Slack threads, meeting prep notes, and SOP drafts all start as voice — dictated in whatever app is open. Command Mode handles edits: "make this more direct," "add a pricing section."
- Fathom captures every call. No manual notes — every discovery session, project check-in, and client update is auto-recorded, transcribed, and summarized.
- Claude turns it into deliverables. The week's Fathom summaries drop into a Claude Project. A Skill generates the audit report, a second Skill writes the proposal, a third updates the SOP library. One project call → finished client deliverable.
- TurboScribe handles the archive. When a client has 50 recorded webinars or a podcast back-catalog they've never monetized, TurboScribe batch-processes the archive overnight. Claude converts it into a content library, a knowledge base, or a course outline.
Sold as "AI productivity stack": $3,500 setup, $1,000/mo maintenance. Tool cost: $47/mo.
The money
The stack math that closes the pitch:
- Voice workflow install (Wispr Flow + Fathom setup, training, custom dict): $1,500 as a standalone. Run 2/mo = $3,000/mo at near-zero fulfillment overhead.
- AI productivity install (Claude Projects + Skills + Fathom + Wispr Flow for a full team): $2,500-$5,000 setup, then $500-$1,500/mo to maintain the Skills library.
- Audio archive project (TurboScribe batch → Claude content pipeline): $500-$2,000 per archive, $200-$500/mo for ongoing batches. Sells easily to coaches and course creators with years of unmonetized recordings.
The voice workflow is the fastest-to-close line item on the consultant menu — it pays for itself before the first deliverable lands.

FAQ
Do these tools work on Windows?
Wispr Flow works on Mac, Windows, iOS, and Android — one Pro subscription covers all devices. Fathom and Otter.ai work on Zoom, Google Meet, and Microsoft Teams across platforms. TurboScribe is web-based, so it works in any browser on any OS. The only Mac-only constraint in this stack is Wispr Flow's "Hey Flow" wake word, which requires the desktop app.
Is voice dictation HIPAA compliant for healthcare clients?
Wispr Flow is HIPAA compliant on all plans. Otter.ai offers a HIPAA add-on at the Enterprise level. TurboScribe uses OpenAI Whisper infrastructure — check their enterprise DPA before using with PHI. Fathom is not HIPAA certified at standard tiers. For healthcare work, pair Wispr Flow (HIPAA-native) with a secure, client-approved storage layer.
Can I sell voice workflow setup as a service to non-technical clients?
Yes — and non-technical clients are the best buyers. The pitch is simple: "I'll set up every device so you can dictate instead of type, and train you for 30 minutes. Most clients never look back." The friction is low, the adoption rate is near-100% after the first session, and it anchors the rest of the AI stack you sell them. See the full service packaging model at AI Tools for Consultants.
What's the difference between Fathom and Otter.ai for consultants?
Fathom's free plan is more generous for individual consultants (unlimited recordings, 5 AI summaries/mo) and the Business plan's CRM sync is best-in-class. Otter.ai's per-seat cost ($8.33/user/mo) makes it the budget pick when deploying across a large client team. Use Fathom for your own calls and Otter for client rollouts where seat count matters.
