Moil writes your business plan for $25. Here is what goes in a small business plan, what it should cost you, and how to get one in an afternoon.

Who Will Write My Business Plan?

Moil writes your business plan for $25. You answer questions about your trade, your service area and your pricing, and Moil returns a lender-ready plan — market analysis, service line, three-year financial projections — in English or Spanish. A consultant charges $2,000 to $5,000 for the same document and takes three weeks. That is the short answer; the rest of this guide is what goes inside the plan, so you can judge whether what you get back is any good.

• $25Moil Plan
• $2,500Consultant
• 30%Faster Growth
• 33%Have a Plan

Only 33% of small businesses have a formal business plan, yet businesses with plans grow roughly 30% faster than those without one, according to a Journal of Management Studies analysis. If you are a contractor, plumber, landscaper or restaurant owner, the plan is not a document for investors. It is the thing that forces you to think about pricing, competition and cash flow before you learn those lessons the expensive way. Once it exists, the next thing you need is a way to market it — that is what the 30-day content calendar covers.

What Does a Business Plan Cost in 2026?

There are three price points, and they buy very different things. A consultant costs $2,000 to $5,000 and takes two to four weeks. A generic template is free and gives you blank headings you still have to fill. Moil sits in the middle on effort and at the bottom on price: $25 for the finished plan, written against your trade, your city and your numbers, with no subscription to keep it.

The 7 Essential Sections of a Business Plan

Every strong business plan — whether for a solo plumber or a 20-person HVAC company — follows the same structure. Here are the seven sections you need:

• Executive Summary: A 1-page overview of your entire business — who you are, what you do, why you will win, and what you need. Write this last.
• Company Description: Your legal structure (LLC, sole prop, S-corp), location, history, and the specific problem you solve.
• Market Analysis: Who are your customers? How big is your market? Who are your competitors and what makes you different?
• Organization & Management: Your team structure, key roles, and who does what. Even if it is just you today.
• Service Line: What exactly do you sell? Pricing tiers, packages, and how your services generate revenue.
• Marketing & Sales Strategy: How customers find you and how you close them. Online, referrals, door-to-door, partnerships.
• Financial Projections: Revenue forecasts, expense budgets, break-even analysis, and cash flow projections for 3 years.

Step 1: Start With Your Market Analysis

Most people start with the executive summary. That is backwards. Start with the market — it shapes everything else. Answer three questions: How many potential customers are within your service area? What do competitors charge? What gap exists that you can fill?

For a plumbing business in Austin, TX, that might look like: 580,000 households within 30 miles, 340 licensed plumbing companies (one per 1,700 homes), average service call $150-$350, and only a small share of competitors offering bilingual service in a market where roughly a third of residents are Hispanic.

Step 2: Define Your Service Line and Pricing

List every service you offer and price each one. Use a tiered approach: Basic, Standard and Premium. For an HVAC company that might be a diagnostic visit ($89), standard repair ($150-$450), full system replacement ($4,500-$12,000) and a maintenance agreement ($25/month). Calculate your true cost per job — materials, labor, drive time and overhead — so each tier is profitable before you write it into the plan.

Step 3: Build Your Financial Projections

This is where most people get stuck. You need three documents: a Profit & Loss projection (monthly for Year 1, quarterly for Years 2-3), a Cash Flow statement (when money actually enters and leaves your account), and a Break-Even Analysis (how many jobs per month you need to cover all expenses).

Example for a 2-person electrical company: if your monthly overhead is $8,500 (truck payment, insurance, tools, phone, software) and your average job profit is $340, you need 25 jobs a month just to break even. Everything above 25 is profit. Moil builds these three statements from the prices and costs you enter, which is the part a blank template cannot do for you.

• $8,500Monthly Overhead
• $340Avg Job Profit
• 25 JobsBreak-Even
• 40 JobsTarget

Step 4: Write the Executive Summary Last

Now that you have done the hard work, condense it into one compelling page. Include your business name and what you do (one sentence), the market opportunity (two sentences), your competitive advantage (one sentence), your financial ask or goal (one sentence), and your projected revenue for Year 1.

Can I Get the Plan in Spanish?

Yes. Every plan Moil writes comes in English and Spanish, at the same $25 — not a machine translation bolted on afterwards, but the same document written twice. That matters in two specific moments: when a bilingual owner needs to hand the numbers to an English-speaking loan officer, and when an English-speaking owner needs the operations section understood by a Spanish-speaking crew. Most plan generators do not do this at all, which is the whole reason we built for it.

Common Business Plan Mistakes to Avoid

• Being too vague: "We will do marketing" is not a plan. "We will spend $500/month on Google Ads targeting emergency plumber within 15 miles" is a plan.
• Ignoring competition: saying you have "no competition" tells a lender you have not done the research.
• Unrealistic projections: if the average plumbing company does $350k in Year 1, projecting $2M needs serious justification.
• Forgetting cash flow: profit on paper means nothing if you cannot cover payroll on the 15th because a customer has not paid yet.
• Writing it and forgetting it: review the plan quarterly. Markets change, and so does your pricing.
