Deep dives
What each tool actually does in your business.
Claude Pro — $20/month
Best for: proposals, client emails, research synthesis, deliverable drafts
If you bill $150/hour and Claude saves you 2 hours a week on writing and research, it pays for itself in the first 40 minutes of the month. The 200K token context window means you can paste your entire project brief, previous emails, and client notes — and get a coherent, on-brand response in one shot.
Skip if...
You're not writing proposals, reports, or client communications regularly. If your work is purely operational/in-person, the ROI is lower.
HubSpot Free CRM
Best for: pipeline tracking, follow-up reminders, contact history
The free tier is genuinely powerful for solo consultants. Pipeline view, contact notes, email tracking, and deal stages — all free. The upgrade to Starter ($20/mo) only makes sense once you have consistent lead volume and need sequences or more reporting depth.
Skip if...
You have fewer than 5 active prospects at any time. A simple Notion table does the job. Don't over-engineer early.
Systeme.io — Free to $27/month
Best for: consultants who want one tool instead of five
Replaces: landing page builder + email tool + funnel builder + course platform. The free plan covers 2,000 contacts, 3 funnels, and unlimited emails — enough for most solo consultants for the first 12–18 months. If you're starting from scratch and want to minimize subscriptions, start here before adding specialist tools.
Skip if...
You already have HubSpot + Kit set up and they're working. Don't migrate a functional system to save $20/month.
