common mistakes when making a budget

However, reality shows that many businesses still encounter difficulties because of basic mistakes in the process of building and managing the budget. These limitations not only reduce the efficiency of capital use but also directly affect the ability to grow.

This article will share with Bizzi 5 common mistakes when budgeting so you can identify and fix it promptly.

Unrealistic Expectations & Poor Forecasting

One of the most common mistakes in working capital management is setting targets and forecasts that are not based on facts, leading to financial planning that is far from reality. These shortcomings often stem from three main causes:

Lack of basis and subjectivity in goal setting

Many businesses set financial goals based on feelings, lacking specific data, for example "revenue increased by 10%" but without market analysis. In addition, overestimating profits and ignoring actual costs can easily lead to capital deficits. The solution is to apply the principle of SMART to ensure clear, achievable and measurable goals. In particular, the mistake of Static Budgeting often makes plans quickly become outdated. Instead, consider applying Rolling Budgeting or Flexible Budgeting to adapt to the market.

Based on old data, lacking adjustment for market fluctuations

Budgeting based solely on previous year data without updating the economic situation, customer demand or new policies will make the business less flexible. At the same time, ignoring risk factors such as inflation, taxes, and demand fluctuations will make forecasts inaccurate and difficult to control.

Lack of Scenario Planning

Many businesses do not build good – average – bad scenarios, leading to passivity when the market changes. Incorrect forecasts can cause businesses to have to borrow capital urgently, incur high costs, and even affect reputation, legality and employee morale. In addition, not applying Zero-Based Budgeting (ZBB) when necessary will miss the opportunity to re-evaluate all expenses from zero, thoroughly optimizing resources.

Lack of Flexibility & Adaptability

In a rapidly changing business landscape, one of the biggest mistakes when set a budget Finance is a lack of flexibility and adaptability. This often leaves businesses “tied up” by market fluctuations, making it difficult to take advantage of new opportunities and vulnerable to risks when costs exceed plans.

Fixed budget

Many businesses prepare their financial budgets once at the beginning of the year and keep them the same throughout the year. This practice causes budgets to quickly become outdated as the business environment, raw material prices, or tax policies change. As a result, businesses have to make decisions based on outdated data, limiting innovation and reducing competitiveness.

No frequent adjustments

In reality, income and expenses fluctuate constantly over time. If the budget is not updated periodically, businesses will have difficulty responding to fluctuations in customer demand, which can easily lead to cash flow shortages or overspending.

Budget does not match business characteristics

Some businesses apply a common budget template without considering the industry, scale or operating model. This makes the budget far from reality, not reflecting the needs and development goals of each business.

To overcome this, businesses should adopt a flexible financial budgeting model that allows for regular adjustments based on actual data. Incorporating digital tools cost management also helps automatically update and analyze, thereby supporting the management team to make decisions faster and more accurately.

Poor Data Management & Outdated Tools

One of the common mistakes that make financial budgeting ineffective is unscientific data management and the use of outdated tools. Many businesses still encounter the following problems:

  • General information, lack of details: When financial data is not analyzed in depth or only stops at summary numbers, it is difficult for management to make timely decisions, especially in the stages of approving or adjusting the budget.
  • Complex, inefficient forms: Using disjointed, confusingly designed, and non-inheritable forms results in wasted time and is prone to errors.
  • Using outdated tools:
    • Many businesses still rely heavily on traditional Excel spreadsheets. This may be fine for small volumes, but as data becomes larger and more complex, Excel can easily create a disconnect between the financial budgeting process and the overall business strategy.
    • Using Excel creates disjointed data that is not linked to the ERP System (like SAP, Odoo). This poses a Data Integrity risk, increasing the Cost of Information Retrieval for both internal and Google.

Lack of Collaboration & Communication

One of the major barriers to financial budgeting is the lack of coordination between departments. Without full participation and transparent communication, budgets can easily become “paper documents” rather than practical management tools. Common problems include:

  • Budgeting is a departmental matter.: When only the finance department is involved, the budget does not accurately reflect the actual needs of other departments.
  • Top-down targets: Goals set by leaders often lack a realistic basis, leading to unfeasible plans.
  • The bottom-up “budget game”: Departments tend to set low targets and high costs to easily achieve their goals.
  • Lack of communication between departments: Lack of transparent data makes overspending difficult to monitor effectively.
  • No clear time plan: The budget was established in a hurry and without preparation, so it was prone to errors and lacked feasibility.

Neglecting Contingencies & Irregular Expenses

A common mistake in financial budgeting is to focus only on daily expenses and ignore unexpected expenses or contingency funds. This makes businesses vulnerable to passive situations when unplanned fluctuations occur.

Forget about irregular expenses

Businesses often overlook recurring expenses that do not occur monthly such as insurance, taxes, audit fees, or machine maintenance costs. Failure to account for these in the budget results in cash flow discrepancies when they arise. In particular, businesses often forget about costs related to maintaining Legal Compliance such as fees. long-term storage of electronic invoices, audit fees as prescribed.

No reserve fund

A budget that is too “rigid” will lack the flexibility to handle emergencies such as fluctuations in raw material prices, unexpected increases in operating costs, or system failures. Not preparing a contingency fund in advance will disrupt your financial plan and affect your business progress.

Solution: Enterprises should proactively set aside a reserve fund of about 5-10% of total OPEX (Operating Expenses) annually. This amount will act as a "safety buffer" to help enterprises maintain financial stability, minimize risks and promptly respond to unexpected fluctuations. Good cost management also ensures that enterprises comply with legal aspects of electronic invoices.
