The Solopreneur Business Stack
Six tools that let one person deliver, automate, document, and bill like a team of five.
You are the entire company. Sales, delivery, support, and operations all land on you, and the only way that works is if the boring half runs itself.

Why These 5 Tools Work Together
The constraint in a solo business is attention, not money. Every tool here buys back hours in a specific, nameable way — or it does not belong in the stack.
Documents and records are different problems. Notion holds the thinking; Airtable holds the pipeline. Forcing one tool to do both is the most common solo-stack mistake.
Automate the handoffs, not the work. The lost hours live between steps: the proposal that never got followed up, the invoice that never got sent.
The combined workflow: Win work through proposals written in ChatGPT and hosted in Notion, track it in an Airtable pipeline, let Zapier move deals through stages and trigger Stripe invoices, and deliver updates as Loom videos instead of meetings.
Who This Stack Is For
A one-person business fails in one of two ways: you sell nothing, or you sell so much that delivery buries you. This stack is aimed at the second failure, because the first one is a positioning problem no software fixes. ChatGPT Pro is the deliberate splurge — at $200/mo it only makes sense if you are genuinely using extended reasoning for client work, analysis, or code, and if you are, it replaces a contractor. If you are not there yet, Plus at $20 runs this stack perfectly well. Notion is where the business lives: SOPs, client pages, proposals, and the wiki that means you can hand work off the day you hire. Airtable holds the structured side — pipeline, projects, inventory — because trying to run a pipeline in a Notion database eventually hurts. Zapier Professional is the difference between two-step toys and real multi-step automation with filters and paths. Stripe bills and takes payment. Loom makes you present in ten places at once. Roughly $290/mo at the top configuration, or $110 with ChatGPT Plus. Either way, less than a part-time hire.

Your Stack, Tool by Tool
A breakdown of each tool, what it does in this stack, and how to get started.
ChatGPT Pro
Analysis & Production
Extended reasoning for the work you would otherwise outsource — analysis, code, strategy documents. Plus at $20 covers everyday drafting if Pro is overkill.
Key feature: Deep reasoning modes that hold a complex problem across a long session.
In this stack: Drafts everything that lands in Notion and every client-facing document.
Notion
Company Wiki & Client Portals
SOPs, proposals, project pages, and shared client portals. The place a future hire reads to understand how the business runs.
Key feature: Shareable pages with permissions — a client portal without building one.
In this stack: Links to Airtable records and embeds Loom updates on client pages.
Airtable
Pipeline & Operations
Structured records for deals, projects, and deliverables, with automations and interfaces that make it feel like a custom internal tool.
Key feature: Interfaces turn a base into a dashboard you can show a client.
In this stack: Source of truth for Zapier automations and Stripe invoice triggers.
Zapier Professional
Automation
Multi-step Zaps with filters, paths, and error handling. This is where automation stops being a demo and starts removing real admin.
Key feature: Paths let one trigger branch by deal size, client type, or stage.
In this stack: Connects Airtable, Stripe, Notion, and email into one operating loop.
Stripe
Billing & Payments
Invoices, subscriptions, and payment links without an accounting platform. Retainers on card file end the monthly chase.
Key feature: Payment links you can drop into a proposal and get paid the same day.
In this stack: Triggered by Zapier when an Airtable deal hits Won.
Loom
Async Communication
Client updates, feedback, and onboarding as short videos. One recording replaces a recurring call that costs you an hour a week.
Key feature: Transcripts and timestamps make videos searchable later.
In this stack: Embeds directly in Notion client pages and Airtable project records.
