I run a one-person business. Here are the 70 AI prompts I actually use daily (2026 edition)

I run a one-person business. That makes me the head of sales, marketing, support, AND bookkeeping. After 6 months of trying every AI tool on the market, here's the 70-prompt kit I actually use daily.

The honest premise

When I started using AI for my business in early 2026, I went through the same arc everyone does:

  1. Excitement. "AI can do EVERYTHING!"
  2. Disappointment. "Why does it hallucinate my pricing?"
  3. Refinement. "OK, here's how to actually get value."

The refinement phase is where most people stall. They have a vague sense that AI is useful, but no specific workflows that work reliably. They prompt the AI like Google, get mediocre output, and conclude "AI is overhyped."

I went through the same. What got me to the other side was a set of 70 specific prompts that I'd tested 10+ times each, for workflows I actually run. Below are the 5 categories I use most, with example prompts.

Category 1: Customer communication (12 prompts)

The biggest time-sink in any small business is replying to customer emails. Most of them are variations on 5 themes:

  • "Where's my order?"
  • "Can I get a refund?"
  • "Do you offer [X]?"
  • "How does [feature] work?"
  • "I have a feature request"

I have one prompt for each variant. Each prompt outputs a draft reply that I review in 5 seconds, edit, and send. Average time per email: 30 seconds instead of 5 minutes.

Example prompt:

You are the support lead for a small e-commerce business selling [products]. A customer has emailed asking for a refund because they "didn't receive the item." Draft a 3-paragraph reply that:

  1. Acknowledges the frustration without being defensive
  2. Asks for the order number (if not provided) and shipping address
  3. Explains the refund process and expected timeline (3-5 business days)

Tone: warm, helpful, professional. Do not apologize excessively. Do not make promises you can't keep. If you don't know the answer to a specific question, ask for it rather than guessing.

This prompt gets me 80% of the way to a perfect reply. I edit the specific order number, hit send, move on.

Category 2: Marketing copy (18 prompts)

I used to spend 2 hours writing a single blog post intro. Now I spend 15 minutes. The prompts cover:

  • Blog post outlines
  • Email subject lines (A/B variants)
  • Social media posts (LinkedIn, Twitter, Facebook)
  • Product descriptions
  • Ad copy (Google, Meta)
  • Landing page hero text
  • Newsletter intros

Example prompt for LinkedIn posts:

Write a 200-word LinkedIn post about [topic] for [target audience]. Structure:

  • Open with a counterintuitive claim or specific number
  • Tell a brief story (1-2 sentences) that illustrates the claim
  • Explain why the conventional wisdom is wrong
  • End with a single, clear takeaway

Voice: direct, slightly contrarian, no jargon. Use line breaks between paragraphs (no bullet points). Avoid hashtags except 2-3 at the end.

This prompt gets me to a publishable LinkedIn post in ~3 minutes. I rarely edit more than a few words.

Category 3: Financial admin (10 prompts)

The category nobody talks about: bookkeeping. As a one-person business, I do my own books. AI is shockingly good at:

  • Categorizing transactions ("is this a business expense or personal?")
  • Drafting monthly financial summaries ("explain P&L to my non-finance partner")
  • Reconciling Stripe payouts against bank deposits
  • Generating invoice descriptions from work logs
  • Drafting IRS-style expense narratives

Example prompt:

I run a small consulting business. Below is my bank statement for [month]. Categorize each transaction as:

  • business_revenue (with category: services/products/passive)
  • business_expense (with category: software/marketing/travel/office/professional/other)
  • personal (ignore)

Output as a table: date | merchant | amount | category | notes

Bank statement:
[paste CSV]

This prompt saves me 2 hours/month on bookkeeping. The categorization is 95% accurate — I just review the "unsure" rows and correct them.

Category 4: Sales (15 prompts)

Selling without a sales team means YOU write every email, every proposal, every follow-up. AI is excellent at:

  • Cold email subject lines (5 variants)
  • Cold email body (4-sentence pitch with one specific question)
  • Proposal scoping (turn 30-min call notes into a 1-page doc)
  • Follow-up emails (3-day, 7-day, 14-day cadences)
  • Objection handling ("they said X, here's how to respond")
  • Pricing justification ("they want 30% off, here's how to frame the value")

Example prompt for follow-up emails:

A prospect received my proposal 7 days ago. They haven't responded. Draft a 3-sentence follow-up email that:

  1. References the specific proposal topic (not generic)
  2. Offers a specific next step (15-min call, revised quote, or answer to a likely objection)
  3. Provides an easy out ("if timing isn't right, no worries")

Tone: low-pressure, professional, human. Do not include any sales cliches ("just checking in," "circling back," "touching base").

I have 3 versions of this prompt (3-day, 7-day, 14-day cadences). They output 90% of my follow-up emails unedited.

Category 5: Operations (15 prompts)

The unsexy category that actually runs the business:

  • Meeting agenda templates
  • Project status updates ("what did I do this week?")
  • Standard operating procedures (turn tribal knowledge into doc)
  • Vendor research (compare 3 options in a table)
  • Tool comparisons ("Notion vs Obsidian vs ClickUp for my use case")
  • Process documentation ("explain this script to a junior dev")

Example prompt:

I'm a one-person business. Every Friday I need to write a status update for myself (and sometimes my accountant). Generate a template with these sections:

  1. Revenue this week (paste Stripe payout amount)
  2. New customers (count + names)
  3. Key blockers (1-3 items, with proposed resolution)
  4. Next week's priorities (3-5 items, in priority order)
  5. Total hours worked (with rough split: client work / admin / marketing / learning)

Fill in the template based on my notes below. Keep total length under 400 words. Use bullet points.

Notes from this week:
[paste stream-of-consciousness notes]

I run this every Friday. Saves me 45 minutes of staring at a blank doc.

The full kit

These are 5 of the 70 prompts in my actual kit. The full Field Kit 01 covers:

  • Customer communication (12)
  • Marketing copy (18)
  • Financial admin (10)
  • Sales (15)
  • Operations (15)
  • Personal productivity (8)
  • Hiring & HR (4)
  • Strategy (6)
  • Personal growth (4)
  • Misc / wildcard (3)

Each prompt has been tested at least 10 times in my actual business. I update them quarterly based on what works.

The full kit is $9 (one-time purchase). The free 10-prompt sampler is below.

When AI prompts DON'T work

The honest list:

  1. Anything requiring real-time data. AI doesn't know today's weather, this morning's news, or my bank balance right now. For those, use a tool with live data.

  2. Anything requiring deep context I haven't provided. If I ask AI to "draft a proposal for the Smith project" without telling it what the Smith project is, I'll get generic garbage. The prompts work because they include the relevant context inline.

  3. Anything requiring emotional nuance I can't specify. "Write a heartfelt apology to a customer who just lost their job because of our product delay" — I can prompt this, but the AI will produce something that reads like a template. Real emotional communication needs a human.

  4. Anything where the AI is overconfident about facts. AI makes up case law, medical studies, and historical events with the same confidence it states true facts. For anything factual, I always verify.

The ROI

Before using AI prompts: ~60 hours/month on admin, marketing, finance. Revenue: $4k/month.

After: ~30 hours/month on the same tasks. Revenue: $5.5k/month.

The 30 hours/month saved translates to either (a) more client work (revenue) or (b) more personal time (life quality). I split it 60/40.

For a $9 prompt pack, the payback period is one task.
