Posted By


This article is part of our series on Lean Planning, where we will go into more detail on aspects of the Lean Planning process. Start with How to Build a Lean Business Plan Step 1: Create Your Business StrategyHow to Build a Lean Business Plan Step 2: Develop Your Tactics, and How to Build a Lean Business Plan Step 3: Set Milestones.

For a comprehensive overview of Lean Planning, check out An Introduction to Lean Planning.

This is the fourth article in my series on creating a Lean Business Plan; as a quick refresher, lean business planning is a faster, simpler way to develop and refine your business strategy. Instead of writing a long, traditional business plan, Lean Planning focuses on the basics and gives you a process that greatly increases your chances of success.

So far, I’ve discussed how to develop your strategy, define the tactics that you’ll use to implement your strategy, and come up with milestones for testing and building your business idea. You can take a look at those posts if Lean Planning is new to you, or get up-to-speed quickly by reading my Lean Planning overview.

In this post, I’ll review the last component of your Lean Plan—your business model. financial dashboard

Defining the business model

Your business model is a description of how your business is going to make money. Your business model describes where your revenue comes from and what your key expenses are.

Most business models are fairly straightforward: your company sells a product or service to your customers and you have a budget to cover your expenses. To be a profitable business, your income just needs to be greater than your expenses.

Other business models can be more complex. Take Google, for example. They give away their primary product (internet search) for free and charge advertisers to put ads on those search results. In this business model, Google has two customers: people who search and advertisers who buy ads. Google needs to please both of them to make their business work. Granted, this is a massive over-simplification of Google’s business model, but hopefully, you get the idea.

Start by describing your business model—skip the numbers

When you’re creating your Lean Plan, you can initially skip the detailed financial forecast. This makes planning faster and easier and helps you focus on what matters most—your strategy. If you don’t have a product or service that customers want, having a detailed financial forecast won’t matter.

So, focus on making sure you have a solid strategy first. You’ll get to the detailed financial forecasts later.

Start out by just describing your business model. Where does your revenue come from? If you sell different types of products and services, list them. Next, list out your key expenses. You don’t need to know exactly how much the expenses will be, just a list of what they are.

Using Garrett’s Bike Shop as an example, we might list out revenue streams for bikes, clothing, accessories, and bike maintenance. Garrett would have an expense list that would include salaries for employees, rent, marketing, utilities, and insurance.

The goal here is to document how your business works as quickly as possible while you spend time figuring out your business strategy.

Creating a financial forecast for your business model

When you’re ready and you’ve validated that your prospective customers are interested in your business idea, then it’s time to move on to create a more detailed business model.

This time, you’ll want to actually figure out and forecast your revenue and expenses, plan for purchasing assets, and figure out if your business can actually be profitable. These forecasts will also help you figure out how much money you’ll need to start your business and get through the early days.

You should create the following projections:

  • Sales forecast
  • Expense budget
  • Profit and loss
  • Cash flow
  • Balance sheet

This may sound like a lot, but it’s really not as daunting as it seems. You can make forecasting even easier if you use a tool like LivePlan, but you can also get by with spreadsheets.

When you create your forecasts, use educated guesses to guide you. Remember, no one actually knows the future, so your job is just to make good guesses at how many customers you can acquire, what they’re going to spend with you, and how much it’s going to cost you to run your business.

In previous posts, we’ve gone into more detail on forecasting sales and creating your budget. Start with these posts to learn what it takes to create the forecasts you need:

Remember, forecasting is just educated guessing, so you’ll probably go through the process a few times before you get it right. Even then, you’ll probably need to return to your forecast on monthly or quarterly basis to adjust it as your business grows. That’s what we do here at Palo Alto Software even though we’ve been in business for more than 20 years!
