Stack · Pricing
The complete consultant stack
under $100/month.
Most consultants overpay for tools they underuse, or underpay and build on tools that can't support the workflow they actually need. Here's the right stack at three stages of a solo consulting practice — with exact pricing.
The principle
Stage-appropriate tools. Not aspirational ones.
The most expensive mistake in consultant tool selection is buying for the business you're planning to have rather than the one you actually have. A consultant with 3 active clients does not need the same stack as one with 30.
Tools follow workflow
Map your workflow first — what happens between "prospect" and "paid invoice." Every tool should serve a specific step in that workflow. If you can't name the step, you don't need the tool.
Free tiers are real
HubSpot CRM, Notion, Calendly basic, Make (1,000 ops/month), Fathom meeting recorder — all genuinely free for solo operators. Under $30/month gets you a functional OS if you choose correctly.
Add when the pain is real
Upgrade tools when the current one is creating measurable friction — not when a better tool exists. Premature optimization costs money and time. The free tier is the right starting point.
Stage 1 — Starting out
0–5 active clients: $0–$29/month
At this stage the OS is about getting the basics running without over-engineering. Free tools cover everything you actually need.
| Layer | Tool | Cost | What it handles |
|---|---|---|---|
| CRM | HubSpot Free | $0 | Pipeline tracking, contact history, email tracking, meeting scheduler, follow-up tasks |
| Scheduling | Calendly Free | $0 | Discovery call booking link — 1 event type on free tier, enough for this stage |
| AI | Claude Free | $0 | Proposal drafting, email writing, research synthesis, meeting prep |
| Delivery | Notion Free | $0 | Client workspace, project tracking, SOPs, personal knowledge base |
| Meetings | Fathom Free | $0 | Unlimited Zoom recording, AI summary, transcript — feeds directly into proposal AI prompt |
| Proposals | Google Docs | $0 | Professional enough at this stage — upgrade to PandaDoc when close rate matters more than speed |
| Kit Free | $0 | Newsletter and simple broadcast emails — upgrade to ActiveCampaign when you need behavioral triggers | |
| Stage 1 Total | $0/mo | Fully functional OS for early-stage solo consultant | |
Stage 2 — Active practice
5–15 active clients: $49–$79/month
This is where automation earns its cost. Manual onboarding, follow-up, and admin at this volume consumes 10+ hours per week — worth $500–$2,000/month in billable time at almost any consultant rate.
| Layer | Tool | Cost | What it handles |
|---|---|---|---|
| CRM | HubSpot Free | $0 | Still sufficient — HubSpot's free tier handles this volume with no issues |
| Automation | Make Core | $9/mo | The most important upgrade at this stage. Automates onboarding sequence, follow-up reminders, invoice triggers. 10,000 ops/month covers a busy solo practice. |
| Scheduling | Calendly Standard | $10/mo | Multiple event types, workflows (pre-meeting reminders, post-call follow-up), Make integration trigger |
| AI | Claude Pro | $20/mo | Extended context window for long proposal drafts, priority access, 5× more usage. Worth it at 3+ proposals/month. |
| Proposals | PandaDoc Free | $0 | 5 docs/month — enough for most solo practices. Branded proposals with e-sign; significant close rate improvement over Google Docs. |
| Delivery | Notion Free | $0 | Client workspaces, project tracking, SOP library |
| ActiveCampaign Lite | $15/mo | Behavioral automation — proposal sent trigger, unopened follow-up, onboarding sequence. Justifies cost within one closed deal. | |
| Stage 2 Total | $54/mo | Full automated OS. Saves 8–12 hours/week in admin and manual follow-up. | |
Stage 3 — Scaling practice
15+ active clients: $89–$120/month
At scale, the additions are about capacity — more sophisticated proposal tools, better content systems, and team features for when you start adding contractors. The OS is already running; this stage optimizes it.
| Addition | Why | Cost added |
|---|---|---|
| PandaDoc Essentials ($19) | Unlimited documents, custom domain, payment collection, PandaDoc branding removed | +$19/mo |
| Surfer SEO ($29 Lite) | If building content for organic lead generation — worth it at 4+ articles/month | +$29/mo |
| Notion Team ($8/seat) | Only needed if adding contractors who need Notion access. Free tier covers solo operator completely. | +$8/seat |
The $0 → $97/month progression
