Financial modeling is an intricate job that focuses on building a realistic picture of a firm's financial performance, such as balance sheets, income statements, and cash flows. It involves creating a model capable of forecasting future financials based on past, current, and predictable events.
A startup is a business in its initial stages, usually until it has established itself in the market. These early businesses typically do not have stable income or flexible management teams; hence, accurate financial modeling is especially important.
This blog post will provide an overview of common mistakes made while financial modeling by startups. It will examine the causes and the remedies available to combat those mistakes.
- Understand the importance of financial modeling for startups
- Identify common errors made in financial modeling
- Develop strategies for avoiding mistakes and achieving desired outcomes
Data inconsistency is one of the most common and costly mistakes in financial modeling. Without consistent input data the output and quality of a model is compromised. Therefore, it is important to be aware of the pitfalls and strategies to avoid them.
Reasons for Inconsistent Data
Data inconsistency can arise from a variety of sources, but there are a few common causes that tend to affect startups more so than established organizations. These include manual data entry errors, format inconsistencies, duplicate records and estimations.
- Manual Data Entry Errors: When data is manually entered, human error can cause data inconsistencies from typos or other mistakes.
- Format Inconsistencies: Using different formats or sources of data can also create discrepancies. For example, financial data stored in Excel spreadsheets can become skewed if it is input into a different system and some of the formatting is not transferred.
- Duplicate Records: Duplicate records can be a source of inconsistency, especially if the data is updated in multiple places.
- Estimations: Estimations of data can also lead to inconsistency, as it is impossible to accurately predict what the data will be on an ongoing basis.
How to Make it Consistent
Fortunately, there are steps you can take to reduce the likelihood of data inconsistency.
- Double-check Data: Conducting a back-to-back check of manually entered data is one way to help ensure accuracy and consistency.
- Automation: Automating data entry and formatting wherever possible is a great way to reduce human error.
- Data Validation Rules: Utilizing data validation rules can help ensure data integrity and uncover any potential duplication or other errors.
- Keep Data in One Place: Keeping all data in one centralized location can help to ensure that data is updated in all places at once.
- Review Data: Regularly reviewing and auditing data is a crucial step in keeping data consistent.
Poor Projection Accuracy
When making any financial projections, accuracy is paramount. If a financial model isn’t based on accurate data and assumptions, then decision-makers will be operating on faulty information and possibly make uninformed decisions that could be costly to the startup. To prevent poor projection accuracy, avoiding the following mistakes can help.
Lack of Granularity in Forecasting
One common mistake for startup financial models is not having enough granularity when forecasting revenue and expenses. Startups should break their revenue and expenses down into measurable subcategories to gain a clearer picture of their overall financial picture. For example, separating revenue into “direct sales” and “indirect sales” could provide valuable insights into which sales channels are driving the most revenue. Similarly, breaking expenses down into categories such as “operational” and “marketing” expenses can help financially savvy decision-makers better understand their overall cost structure.
Another mistake related to financial modeling for startups is inconsistent assumptions. Startups should strive to utilize up-to-date assumptions based on the latest market trends and activity when forecasting future business performance. For example, if a startup is projecting revenue from a new product line, it should develop assumptions based on industry data rather than making guesses or relying on past successes. Doing so will ensure decisions are based on current market conditions, thereby helping the startup make better decisions when planning for the future.
Financial modeling is a key component to the success of a startup, and it’s important that decision-makers protract accurate and realistic representations of the business’s future financial performance. Avoiding the mistakes related to poor projection accuracy mentioned above, such as lack of granularity and inconsistent assumptions, can help ensure accurate financial models are used to make informed decisions.
Ignoring Accounts Receivable
Accounts receivable (AR) typically refers to short-term credit that’s extended to customers for goods or services. Depending on the industry, AR accounts can significantly contribute to a business’s cash flow and profitability. As such, it’s critical for startups to make sure they are properly accounting for and monitoring AR accounts.
How Calculation Can Differ by Industry
It’s important to note that calculation of AR can differ by industry. Generally, commercial accounts are those to which credit has been extended; thus, the extent to which a company extends credit to these accounts affects how much money it can generate from those customers. How long a company gives customers to pay their invoices before debt is written off or turns bad also affects AR. Industry terms for the specific period of time within which invoices are expected to be paid can also vary.
For example, in many tech companies, customers can be given up to a year before AR is written off. By contrast, in more traditional business-to-consumer (B2C) industries such as retail and restaurants, invoices are typically due within a few days or weeks. Assessing and understanding these industry-specific trends can help startups avoid costly mistakes.
Best Practices for AR Calculation
When it comes to startup financial modeling, it’s important to ensure that AR calculation is accurate. To do this, it’s best to look for ways to simplify the calculation process. Several best practices for AR calculation are identified below:
- Make sure to properly document contracts and payment terms in order to accurately track and manage receivables.
- Ensure that all AR accounts are properly classified and that any that don’t follow industry norms are identified and addressed.
- Compare current-year results with prior-year results to identify any discrepancies or shift in the types of customers being invoiced.
- Assess the creditworthiness of customers, including their ability to pay, prior to extending credit.
- Regularly compare the aging of receivables with current policy as well as industry standards.
By following these best practices, startups can ensure that their AR calculations are accurate and will not cause costly mistakes down the line.
Unclear Revenue Assumptions
When it comes to financial modeling, startups have a great need to assess their future financial position in order to make informed decisions and measure performance. However, if your assumptions about revenue are not clear, then you may be making errors that could severely impact your outcome. Here are a few common mistakes when it comes to revenue assumptions that startups make.
Accounting for Growth
One mistake that startups make when it comes to revenue assumptions is failing to account for growth. While it may be easy to make assumptions based solely on current revenue, it is important to factor in the potential for growth into any financial model. Failing to account for growth can lead to inaccurate forecasts and results.
Another common mistake is disregarding the impact that seasonality has on a startups revenue. Depending on the type of business, certain months may produce a higher or lower amount of revenue than others. Therefore, it is important to build in seasonal fluctuations into your financial model so you are accounting for any variations in revenue throughout the year.
- Account for growth in any revenue assumptions
- Factor in seasonal trends when predicting future revenue
Unrealistic Cost Estimations
Developing accurate cost estimates is an important factor in financial modeling, particularly for startups. Estimating costs accurately helps startups more accurately identify profitable customer segments and determine whether their planned operations will generate sufficient cash flow to break even. When cost assumptions in a financial model are unrealistic, it can lead to the incorrect conclusion that a business is a good investment.
Why Prevalidating Costs are Key
Validation of cost assumptions is key in creating realistic cost estimates for financial models. By collecting as much data as possible from potential vendors, existing contracts, and existing business practices, financial modelers can make educated assumptions about costs. In some cases, it may even be necessary to survey existing suppliers or potential customers to obtain accurate pricing data.
Advantages of Detailed Cost Estimation
By taking the time to accurately estimate costs for each component that goes into the financial model, startup financial modelers can make more informed decisions. Doing so provides entrepreneurs with a better understanding of their overall profitability, cash flow, and ability to secure loans or investors.
- Accurately estimate revenue/cost assumptions
- Analyze pricing dynamics
- Gain understanding of overall profitability of operations
- Determine ability to secure loans and investors
The financial modeling process can be complex and difficult, but understanding common mistakes can help startups increase their chance of success. In this blog post, we identified seven common modeling mistakes that startups should be aware of and how they can use financial modeling to their advantage.
